Japanese take advantage of the LED lights to communicate underwater

Previously want to talk underwater, we mostly use the ultrasound to send dialogue, but this method is very expensive. Divers are generally expressed in gestures, but which only can pass a simple meaning, but also for the beginners, they may not remember clearly, they would be confused in the crisis and affect communication.

In order to solve the problem of underwater communication, with the help of the LED lights Okinawa, Japan, researchers have developed a set of system, which is used to transmit voice. The Principle is that the sound waves is converted into the LED lights, and then emit to the sensor received by the other and then the light is turn into the sound waves. If the light is blocked, leaving only noise.

The researchers said that the system can only communicate in one meter range at the early stage of development,. But then they took into account the volume, transmission speed, sound, and the diving depth and other factors, finally broaden the scope of application of the system.

Currently, even the distance between the two divers is 30 meters, this underwater communication tools still can be used, either at a depth of 30 meters underwater to communicate. Fully charged, then it can be used for four hours, the system can not only be used underwater, there is no problem that those who are on the shore talk with the divers underwater.

The researchers said that the current system is of large volume, they will be committed to developing a smaller mask to facilitate people to use in different industries.

There is no doubt that LED lighting technology as the third generation of the semiconductor applications also can be perfectly combined with the communication.Nowadays，the LED flood light and LED tube light is most widely used as the representatives of the decorative lighting  and the home lighting in daily life，the LED tube light enjoys a great popularity in our corridor, restaurants, shopping, leisure and entertainment, galleries, exhibition halls and other indoor environments everywhere, the LED flood light is mainly used in city squares, parks, stadiums, the facades of large commercial buildings and hotel, stage, waiting rooms, airports etc. where the higher brightness is needed to illuminate,meanwhile，there a large number of factory engaging in developing and producing the LED light，Lead Lighting is just one of them，which adopts high brightness SMD as the light source of the LED tube and highly integrated and high brightness COB as the light source of the LED flood light so that fully guaranteed stabe and soft light of the LED tube light and octahedron breadth and brightness irradiation range of the LED flood light, while  low voltage constant current driver ensure the AC can be converted into the DC to improve energy efficiency of the LED tube light and LED flood light and reduce the waste heat energy and stroboscopic effect exciting the human eye, the most important is that the LED lighting without adding mercury and other heavy metals harmful to our body and pollution the environment, that’s why the LED light is Known as energy-saving and environmental protection ，login http://www.ledclan.com to learn more features and uses of the LED tube light and surf www.lead-lighting.com to know more awesome LED floodlights and other LED lighting.

What's the LED lighting requirements for low-voltage driver chip

LED lighting requirements for low-voltage driver chip

The input voltage range of the nominal DC of the driver chip should satisfy 8 ~ 40V, which is to cover a wider application needs. Pressure capacity is preferably greater than 45V. When the input is AC 12V or 24V, the output voltage of the simple bridge rectifier will fluctuate with the grid voltage, especially when the voltage is high, the output DC voltage will be high. If there is not wide input voltage range for the driver IC, which tends to be

breakdown when the grid voltage rises, thereby burning the LED light source.

2 the nominal output current of the driver chips required is greater than 1.2 ~ 1.5A. For the LED light source used for lighting, the nominal operating current of 1W LED light source is 350mA, 3W LED light source nominal operating current is 700mA. Power LED light source needs more current, the LED lighting driver IC selected must have enough current output, the driving IC must also be operated at the optimum working area that is 70 to 90% of the full load output when the product is designed. There is poor heat dissipation when the driver IC is used in the small spaces at the full-load output current, which easily lead to fatigue and early failure.

3 the output current of the driver chip must be kept constant, so to stabilize the LED light, no flash. When the Same batch driver chip is used under the same conditions, the output current should be as consistent as possible, which is discrete to be small, so that ensure the effectiveness and orderliness on the high-volume automated production line. For the drive chip whose output current has certain discrete, required the sub-file selection before the factory or production line, adjust the size of the resistor set by the current on the PCB, so that LED constant current driver of LED lamps board produced is consistent with the emission luminance of the similar light source in order to maintain the consistency of the final product.

4 the package of the driver chip should facilitate rapid cooling of the die of the driver chip, such as the die is directly bind on the copper, and there is a direct extension of the pin outside of the package, in order to that the copper foil directly soldered on the PCB rapidly transfer the heat. If the chip that is similar to the 4X4mm through 300 ~ 1,000 mA current for long time, the power consumption and heat is inevitably generated, therefore, the physical and thermal structure of the chip itself is also very important.

5 driver chip anti-EMI, noise and high pressure capability is also related to that whether the entire LED lighting products can pass CE, UL certification, so the advanced topology structure and high-pressure production process should be used when the driver chip is designed.

6 driver chip's own power requirements is less than 0.5W, the switching frequency is greater than 120Hz, in order to avoid visible flicker produced by the frequency interference.

 

In short, LED driver chip urge the green lighting to the development of innovative design. LED lighting without driver chip, requiring multi-functional LED light source driver IC. If the power supply that is less than 36V AC is used for the LED lamps, the non-isolated power supply can be considered; if the choice is 220V and 100V AC power, you should consider the isolating power supply. For the AC 100 ~ 220V drive chip directly used, because the application excessively depends on the volume demanding, there is higher demand, the greater difficulty on the technically, the countries are currently making efforts to develop. The Massive demand for LED lighting market gives the chances of success to all the IC design company again, if rapid transformation and pushing the product as early as possible, then there is a lot chances to win.

What's the main features and working characteristics of the LED light

The correct choice of LED driver IC is essential to reflect the characteristics of energy saving and long life of the LED lights In the field of LED lighting. The advantage of LED lighting can not be reflected without a good driver IC matched,.

LED lighting has been a leap in the recent developments, LED as the green and cleaning light is widely recognized. LED light source is known as long life, energy saving, easy application, low cost, and thus it will receive a flood of applications in home lighting, OSRAM optical semiconductor company surveyed that the global annual shipments of the home lighting lamp was about 50 billion in 2008,.

LED light source technology matures, the lumens per watt LED grow rapidly, prompting its diminishing prices. Taking the 1WLED light, for example, the price in the spring of 2008 is one-third of the price of the spring of 2006, the spring of 2009 has be reduced to one quarter of 2006.

The mass market and a steady growth in demand of the LED green lighting for several years will be super tsunami of the IC industry following VCD, DVD, mobile phones, MP3 on the consumer electronics market!

 

The superiority of high energy saving, long life and good for  environmental protection of the LED lamps is being universally recognized.

1.LED High energy: DC drive, ultra-low power consumption (single tube is 0.03 ~ 1W) the electro-optical power conversion is close to 30%, the same lighting effects is 10% more than that of the traditional energy sources.

2.LED Long life: LED light source is called as longevity lamps. It is the solid cold light source, epoxy resin, there is nearly no loose parts in the light body, and there is no filament that is easy to burn, heat deposition, the fast light fades and other shortcomings, the service life is up to 50,000 hours, the life is 5 times longer than that of the conventional light sources.

3.LED is good for environmental protection: LED is a green light, the environmental benefits is better. The spectra contains no ultraviolet and infrared, low in calories and no flicker, no radiation, and recyclable waste, no pollution, no mercury elements, cold light source, safe touch, typical of the green lighting.

The work characteristics of the LED light

The VF used for lighting of the LED lighting source is of low voltages, which is normally 2.75 ~ 3.8V, IF is generally 15 ~ 1,400 mA. Therefore, the output voltage of the LED driver IC is VFxN or VFx1, IF keep the constant that is at 15 ~ 1,400 mA. There are two kinds of power that are the small power (IF is 15 ~ 20mA) and high power (IF is greater than 200mA) used for the LED light source. The Small power LED is mostly used to produce LED tube light, decorative lights, grille light. The big Power LED is used for household lighting, LED flood light, underwater lights, wall lights, street lamps, tunnel lights, car lights. Power of the LED light source is the device that is suitable for the low voltage, high current drive, the luminous intensity is determined by the current flowing through the LED. the LED light attenuation is caused by the General Assembly Current, the too small current will affect LED luminous intensity. Therefore, LED driver needs to provide constant current power to ensure the safety of high power LED, and to achieve the desired luminous intensity. In the field of LED lighting, the correct choice of LED driver IC is essential to reflect the characteristics of energy saving and long life of LED lights,. Not a good driver IC matched, LED lighting advantage can not be reflected.

LED Light Conversion ecological glass can convert the sunlight or LED lighting in laminated into blue and red to meet the needs of different plants.

Having this magic glass, we are no longer consider whether the light is adequate in the home balcony, kitchen and so anywhere , we can open a "family farm", casually planting their favorite vegetables, fruits, herbs or valuable agricultural plants.

LED Light Conversion ecological glass reduce plant growth cycle, improves that plant growth rate and survival rate is 50% or more by adjusting the LED light and the conversion function of the sunlight light spectrum, while you can save energy so that better use the resources.

The LED light has been applied to the agriculture，which proves that the lighting characteristics of the Semiconductor and practical performance of the LED light has perfectly matched with the agriculture that is closely related to our daily life . Indeed，the LED light as the third generation of energy saving lighting, in addition to present the unique design to associates with the agriculture , but also combine with medicine, art, technology and many other areas to bring us the extraordinary experience and more convenient. Nowadays，the LED flood light and LED tube light is most widely used as the representatives of the home lighting and decorative lighting in daily life，the LED tube light enjoys a great popularity in our corridor, restaurants, shopping,  galleries, exhibition halls and other indoor environments, the LED flood light is mainly used in city squares, parks, stadiums, the facades of large commercial buildings and hotel, stage, waiting rooms, airports etc. where the higher brightness need lighting is needed to illuminate.Meanwhile，there are a large number of manufacturer engaging in manufacturing and researching the LED light，of which the lead lighting is just one，lead Lighting adopts high brightness SMD as the light source of the LED tube and highly integrated and high brightness COB as the light source of the LED flood light, which fully guaranteed stability and soft light of the LED tube light and octahedron breadth and brightness irradiation range of the LED flood light, while the low voltage constant current driver convert the AC  into DC so that improve energy efficiency of the LED tube light and LED flood light and reduce the waste heat energy and stroboscopic effect exciting the human eye, the most important is that the LED lighting wthout adding mercury and other heavy metals harmful to our body and pollution the environment, that’s why the LED light is famous for energy-saving and environmental protection ，login www.ledclan.com to learn more features and uses of the LED tube light and surf www.lead-lighting.com to know more awesome LED floodlights and other LED lighting.

How to choose the heat sink of the LED light and material of the LED lamp shell

In the LED lamps, the heat is directly related to the quality and life，the radiator's main role is that heat generated by the LED chip is continuously exported and distributed to the environment, so that the chip temperature is maintained within the required range , thus ensuring LED lights properly  work. The quality of the heat sink mainly depends on thermal resistance the radiator, the smaller the thermal resistance，the lower the junction temperature of the LED light under the same conditions , the longer the service life of the chip. Under the certain environmental conditions, the heat resistance depends on the sink area of the heat sink, the greater the area of the heat dissipation, the higher the coefficient of the radiation, the smaller the heat resistance, the better the heat dissipation. Thus, LED lamps radiator must have a certain cooling area, while the material making the radiator must have a certain degree of thermal conductivity and high thermal emissivity, the heat conduction is essentially impossible to go outside when LED work. temperature of the air inside the LED beads has reached the 101 degree, the highest temperature is the fifties degrees on the surface of the lamp, a difference of several tens of degrees.

Some lighting designers almost entirely don’t understand the material properties, parrot; because their supervisor or boss also completely don’t know. What the Boss is concern about is the inexpensive and lowest cost. However, if the heat sink material is not applicable, which can not play a real cooling effect, the end result is that the brightness and life of LED beads is reduced, beyond doubt，and thus the overall service life of LED lighting products are also damaged

The material of the Lamp shell

The transparent PVC ,acrylic is adopted for the Low-end products, the PC material is used for the slightly better.

Low-grade goods: PVC, PE, transparent or frosted acrylic.

Mid-range products: PC. Luxury goods: special polymer plastic material. As for the quality of these materials, we all know.

Now many companies do not have their own design, but there is not creativity at all. Most think that as long as the use of LED lamp fixtures, saying he is what the LED industry, especially  some large companies is more so. Instead, I would think that many small exported companies pour a lot of thought on the quality and design of the LED, but having no government support, those big company combining some officials and sexy and inferior products cheat subsidies. This is Market field, many manufacturers seem to be experts no mater what lamps they do, and now those good chips, good technology are hold by the hands of all foreign manufacturers.

Chinese LED industry is generally lack of core technology, experienced excess capacity, product prices, small business failures and other problems and crisis. Today, in terms of policy support funds， may ushering in a good stage of development, but if the core technology and technological innovation do not be improved, it is likely recommit the same error, again facing the overcapacity crisis of LED industry. So many LED manufacturers are desperately looking for such LED lamps whose cost is low to manufacture, there is a reason.

However, LED lighting manufacturers deceive consumers in the way, the consequences are very serious, look, last month, the scale of a billion dollars, "Hung Kee Lighting boss on foot incident" caused many LED lighting manufacturers concerned, I believe that many LED lighting manufacturers will change from the perspective of technological innovation.

Fortunately，there are still a large number of excellent manufacturer engaging in manufacturing and researching the LED light，of which the lead lighting is just one，lead Lighting adopts high brightness SMD as the light source of the LED tube and highly integrated and high brightness COB as the light source of the LED flood light, which fully guaranteed stability and soft light of the LED tube light and octahedron breadth and brightness irradiation range of the LED flood light, while the low voltage constant current driver convert the AC  into DC so that improve energy efficiency of the LED tube light and LED flood light and reduce the waste heat energy and stroboscopic effect exciting the human eye, the most important is that the LED lighting without adding mercury and other heavy metals harmful to our body and pollution the environment, that’s why the LED light is famous for energy-saving and environmental protection ，login www.ledclan.com to learn more features and uses of the LED tube light and surf www.lead-lighting.com to know more awesome LED floodlights and other LED lighting.

What‘s the notes of the life and light decay of the LED lamp

LED light lamp beads

1.LED lamp life

Many LED lighting manufacturers conceal the life, even on the color page of their product catalog, at the nonsensical: casually LED lighting product life can be up to 100,000 hours, or even 150,000, 20 million hours. This is indeed a lot.

2. the light decay of LED lamp beads

As the LED light up, P / N junction and the entire device is immediately aged due to high temperature, so that the luminous efficiency will be gradually reduced, which is a normal phenomenon, and there are so few the factors that affect the LED light failure: ①, the use of inferior LED lamp, the packaging process of the LED lamp beads is flawed, chip cooling can not well be exported from the PIN feet, resulting in that the excessive die temperature makes the chip attenuation is intensified. Brightness decay rapidly. ②, LED constant current driver, there are some LED voltage lead to the LED attenuation. ③, drive current is greater than the rated drive.

If the bottom glue and the white glue of LED lamp is made of poor epoxy resin and the LED lamp beads packaged by the packaging glue, the single light up at 30 degrees, after 1000 hours, the attenuation data is 70% of the light fades， while the light volume will be drastically reduced after the lamp beads is decayed 70%,. Currently the latest international standards infinite the node that the light of the LED lamps is 70%. The ordinary SMD fades of the LED tube light manufactured by the regular large brands is generally is within 5% in 1000 hours.

However，there are still a large number of excellent manufacturer engaging in manufacturing and researching the LED light，of which the lead lighting is just one，lead Lighting adopts high brightness SMD as the light source of the LED tube and highly integrated and high brightness COB as the light source of the LED flood light, which fully guaranteed stability and soft light of the LED tube light and octahedron breadth and brightness irradiation range of the LED flood light, while the low voltage constant current driver convert the AC  into DC so that improve energy efficiency of the LED tube light and LED flood light and reduce the waste heat energy and stroboscopic effect exciting the human eye, the most important is that the LED lighting without adding mercury and other heavy metals harmful to our body and pollution the environment, that’s why the LED light is famous for energy-saving and environmental protection ，login www.ledclan.com to learn more features and uses of the LED tube light and surf www.lead-lighting.com to know more awesome LED floodlights and other LED lighting.

How to choose the power supply and the drive of the LED light

The using problem of the electrolytic capacitor: as far as the use of electrolytic capacitors is concerned, the manufacturers are using electrolytic capacitors as almost 99% of the power of the LED lighting products, the life of the Electrolytic capacitor is completely unable to over 30,000 hours.

The aluminum electrolytic capacitors was generally 105 ℃ / 200 hours 10 years ago,. Which means that life is only 84 days under the conditions of the temperature at 105 ℃! Even down to 85 ℃, life is only 332 days, less than a year! Continue to reduce to 75 ℃, the life will not exceed two years .

Relative to 100,000 hours life and the semiconductor devices and passive components of semi-permanent life, the aluminum electrolytic capacitor is mainly the key components that lead to that the life of the LED is not performing up to the mark

Even if using the latest high-temperature electrolytic capacitors  whose life is 8,000 hours at 105 ℃, according to the estimation formula of the prevailing life of the electrolytic capacitors "temperature decreasing by 10 degrees, doubling the life," then the working life is 16,000 hours at 95 degrees, the working life is 32,000 hours at 85 degrees， the working life is 64000 hours at 75 degrees, if the actual operating temperature is lower, then life will be longer!

The LED driver technology with no electrolytic capacitor, if from the perspective of the technology of the aluminum electrolytic capacitors  ten years ago, aluminum electrolytic capacitors are not capable of LED and other life. Workaround is generally no electrolytic capacitors technology, which is the underlying causes that the technology of no electrolytic capacitors LED driver was popular in previous years,. But the question that can not be said is that what the consequence that the no consequences electrolytic capacitors is adopted is that the performance of LED driver circuit is degradation, indirectly causing  the serious shortage of LED life.

Because the design of the drive and power of no electrolytic capacitor supply is to enhance the power and power efficiency， no general electronics designers can achieve. The most important consideration is cost.

Currently, the Japan ruby ​​capacitor aluminum electrolytic is the manufacturers of the aluminum electrolytic capacitor whose life is exceeded 10,000 hours at 105 ℃ temperature. Those who understand the Electronic devices all know, not for the particularly high-tech products, there are few manufacturers of LED power afford so expensive capacitors.

2 power factor and efficiency: If the power factor can not be improved to 95% and the power efficiency is more than 85%, it is meaningless that LED lighting products is used to replace the traditional lighting.

Therefore, the current 99% of LED lighting products manufacturer (even including all Japanese brand) is totally not up to the so-called basic required standards of the LED lamp.

Low-grade products is purely the power supply that can convert the AC to DC， a little better is those that raises the power factor to between 70 and 85 percent, but the power efficiency is only 70% or even less than 65%. This shows the actual power consumption is that the marked value of the product watts must plus 50 to 60% of power consumption. As for the life of the LED road light even without looking up. Because of its drive，the power life is not 10,000 hours (but at the same time how its cooling effect have to be considered, or even worse ).

3 Because the bipolar power devices is cheaper than the MOSFET，which is generally about 2 cents/pcs, so some designers use the bipolar power devices in order to reduce the cost of the LED drivers, which will seriously affect the reliability of the circuit, as the temperature of the circuit board of the LED drive increases，the effective operating range of the bipolar devices will rapidly reduce, which will lead to the malfunction when the temperature of the device rises so that the reliability of LED lamps is affected, the correct approach is to use MOSFET devices, the life of the MOSFET device is much longer than bipolar devices.

However，there are still a large number of excellent manufacturer engaging in manufacturing and researching the LED light，of which the lead lighting is just one，lead Lighting adopts high brightness SMD as the light source of the LED tube and highly integrated and high brightness COB as the light source of the LED flood light, which fully guaranteed stability and soft light of the LED tube light and octahedron breadth and brightness irradiation range of the LED flood light, while the low voltage constant current driver convert the AC  into DC so that improve energy efficiency of the LED tube light and LED flood light and reduce the waste heat energy and stroboscopic effect exciting the human eye, the most important is that the LED lighting without adding mercury and other heavy metals harmful to our body and pollution the environment, that’s why the LED light is famous for energy-saving and environmental protection ，login www.ledclan.com to learn more features and uses of the LED tube light and surf www.lead-lighting.com to know more awesome LED floodlights and other LED lighting.

How to maintain the LED automotive light

What the acronym of the LED in English is Light Emitting Diode, as early as the 1960s, it has already started to been produced and has been widely used in household products in 1980, such as audio volume indicator, switch instructions. In the 1990s, the LED has been used in some of the new domestic automobile instrument, mainly used for charging instructions, and later also shows engine speed conditions, such as a combination of instruments produced in Xiangfan Hubei China, a row of LED were erected next to the odometer, When the driver stepped on the gas，the LED bar lights were bottom-up lit, when off the accelerator，LED bar lights bottom-up go out, quite eye-catching and beautiful. In 1990s, China used LED brake light to install in the car, the LED lights up quickly, so that the driver trailing the behind car know what the condition in front of the vehicle to reduce rear-end collision accidents as early as possible.

The Category of LED auto-lights: mainly divided into external and internal lighting fixtures. Common lamps are: headlight, turn signals, taillights, fog lights, rear lamps and so on. The following describes what’s the main maintenance and use of the light.

Lighting repair

In general, as long as not bright, it shows that the lamp has been burned, which must be replaced. But if not completely broken, but decrease in brightness, the lighting is redness and dim, it must not be taken lightly, because this could be a precursor to failure, the ability of the lighting that has been reduced also major risks of the drive safely.

There are several reasons for the decrease brightness, the most common is that there is a plot of dirt on astigmatism lamp glass or the mirror, then what need to do is that use cloth or lens paper to clean the dirt. Another reason is that the capacity of battery charge is decreased, electricity shortages lead to that the bright isn’t enough, so the batteries need to be replaced. Another possibility is that the lines has aged or wires is too small, resulting in that the resistance is increased and thus affect the power supply, this situation affects not only the bulbs work, serious that even lead a fire.

【Maintenance】 various lights

Headlamp:

Generally speaking, the friend who often burn the midnight oil should consider replacing one pair of headlights whose brightness is higher, so that the enough bright help you see all the details on the road and allows you to see farther when it comes to playing away at the dark night. If conditions permit, you can even replace one pair of LED headlamps, which not only ensure the bright, long life, but also has a feature: Color temperature is very high, the color temperature that is close to daylight is kind of protection on the driver's eyes.

Taillights:

Do not underestimate the taillights, if the taillights is broken, which can easily lead to rear-end accidents. Generally speaking, if not failure, n addition to the installation of the transparent lamp to increase the ornamental, replacing the bulbs with the led light is a good choice, led not only increase the brightness, response time has been shortened over that of the traditional light bulb, which means that when you depress the brake pedal, led brake lights can be much earlier lighted up than ordinary light bulbs, so that the trailing vehicle have more preparation time.

Fog light:

Fog light is often said as the spotlights. As the name implies, the main purpose of the fog light is to ensure the driver's view in bad weather, and to ensure that others can see you, but now for many companies, the purpose of installing fog lights is just to make the front bumper more beautiful, so the quality of the Fog light chosen is relatively poor. As the same as the headlamp, beside replace the fog lights whose bright is enough, choosing a hid xenon fog lamps are also a good choice.

Rear lamps:

Reversing is really a headache at night, especially the drivers whose eyesight is not good, there is actually not much help for the faint light of the original reversing lights. Then you need a reversing lamps, which is a independent lamps that is installed in the rear protection bar or at the bottom, it automatically light up after you hang down the reverse gear, its strong brightness makes you are no longer nervously when reversing at night.

The LED light has been applied to the car，which proves that delicate appearance and practical performance of the LED light has perfectly matched with the world's most hottest vehicle. Indeed，the LED light as the third generation of energy saving lighting, in addition to present the unique design to associates with the car , but also combine with medicine, art, agriculture and many other areas to bring us the extraordinary experience and more convenient. Nowadays，the LED flood light and LED tube light is most widely used as the representatives of the home lighting and decorative lighting in daily life，the LED tube light enjoys a great popularity in our corridor, restaurants, shopping,  galleries, exhibition halls and other indoor environments, the LED flood light is mainly used in city squares, parks, stadiums, the facades of large commercial buildings and hotel, stage, waiting rooms, airports etc. where the higher brightness need lighting is needed to illuminate.Meanwhile，there are a large number of manufacturer engaging in manufacturing and researching the LED light，of which the lead lighting is just one，lead Lighting adopts high brightness SMD as the light source of the LED tube and highly integrated and high brightness COB as the light source of the LED flood light, which fully guaranteed stability and soft light of the LED tube light and octahedron breadth and brightness irradiation range of the LED flood light, while the low voltage constant current driver convert the AC  into DC so that improve energy efficiency of the LED tube light and LED flood light and reduce the waste heat energy and stroboscopic effect exciting the human eye, the most important is that the LED lighting without adding mercury and other heavy metals harmful to our body and pollution the environment, that’s why the LED light is famous for energy-saving and environmental protection ，login www.ledclan.com to learn more features and uses of the LED tube light and surf www.lead-lighting.com to know more awesome LED floodlights and other LED lighting.
