How to arrange lighting

Identify our needs. How to arrange lighting depends on our lifestyle. So, we need to develop a home lighting plan to meet what our family need. When planning our lighting, we need to analyze the type of activity in each room, the atmosphere we want to create (light and dark, light and shadow, modern and traditional and so on), the decor elements we want to emphasize. Remember, the light will be absorbed and wasted in a dark room, which is differently for a light colored room, the light is reflected and wasted. In addition, I want to emphasize is that if there are a variety of activities in a room，for example, the living room，a variety of ways need to be set to meet different lighting illumination.

The first way of lighting: general lighting

   

General lighting provides an area with overall illumination，which is ambient lighting mentioned by the designers，general lighting provides a comfortable brightness, ensuring the safety of walking so that we can see the objects. Which light we should use? Don’t worry, we can use ceiling lights, wall lamps, embedded lamps, track lighting, and even adopted the use outdoor lighting. General illumination is the most basic lighting we layout.

The second way of lighting: task lighting

   

Task lighting is to help us to complete specific tasks, such as reading in the library, and washing clothes in the laundry room, cooking in the kitchen, playing video games and so on. We can use the embedded lamps, track lamps, ceiling lamps, portable lamps. In addition we shall avoid glare and shadows when using these lamps, but there must be bright enough to avoid visual fatigue.

A third way of lighting: accent lighting

   

Accent lighting give the room to increase dramatic effect to create excitement. As an element of decoration, we can not only use it to light up paintings, sculptures, and other decorations, but also stress the material of walls or fabric (such as curtains)，which can also be used for outdoor scene lighting. For the accent lighting mode, the central illumination required is three times more than the surrounding. We can use track lighting, recessed light fixtures or wall lamp to meet these.

What do LED grow lighting make effect on plants

1. Different wavelengths of light make different effect on the photosynthesis, plants are different, the wavelength of light the plant need to photosynthesis is about 400-700nm. 400-500nm (blue) and（610-720nm (red)，which makes the greatest contribution to photosynthesis.

2.The light emitted by LED grow lighting is a combination of two colors. For the visual effect, the combination of red and blue lights shows pink.

3 blue light promote leaf growth; red light helps to prolong flowering and fruiting and flowering!

4 When LED grow lighting pour light to a plant，the gap between the leaves and LED grow lighting is generally about 0.5 meters, which continuously illuminating for 12-16 hours a day can completely replace the sun.

        

The advantages of LED grow lighting:

· Reduce cultivation costs, extend the flowering period

· Promote plant precocity, increase production, improve the quality of fruits

• Ensure the taste of greenhouse vegetables, to achieve in-season cultivation

· Inhibit bacteria and pests breeding, reduce the amount of pesticides, green and no pollution

What are the other five questions for the design of the LED tube light

1.What is the  relationship between PFC power factor and wide voltage of LED series-parallel?

There are currently three kinds of PFC power supply on the market: one is dedicated circuit without PFC, the PFC is generally about 0.65; one is with a passive PFC circuit, the light board match well, the PFC is generally about 0.92; there is PFC power supply with an active 7527/6561 circuit, which can reach 0.99, but the cost of this program as twice expensive as the second solution. So as The secondary program. For passive PFC circuit，which is also called a valley-fill PFC circuit, the operating voltage range is half of the peak voltage of the AC input. If the input is 180V, the peak is 180 * 1.414 = 254V, the half of the peak voltage is 127V, a step-down pressure minus is 30V, the maximum output is 90V, so the maximum number of series LED lamp is 28 strings. Therefore, to get relatively large power factor, the number of lamp beads series should be not too much, otherwise, it can not reach the low voltage requirements.

   

2, how much current precision of power supply of LED tube T5 and T8 would be the most appropriate?

some of precision constant current of power supply on the market is too bad, such as the popularity of the constant program, including PT4107/HV9910/BP2808/SMD802 programs whose deviation is ± 8% or ± 10%, the constant deviation is too large. General requirements is ± 3%. Deviation is 3%, for the 6 parallel, each of the deviation is about ± 0.5%, if the 12-way parallel, each of the error is about ± 0.25%, the accuracy is sufficient. Accuracy is too high, the cost will be greatly increased. And, 17 mA and 17.5 mA make little effect on LED.

3, isolated / non-isolated

The transformer of 15W isolated power placed inside LED tube T5 and T8 is generally bulky, it is difficult to put into the tube. Especially for T5/T8 lamp, so the LED tube T5 and T8 with isolated power is generally 15W, those exceeding15W are rarely, and the price is very expensive. So the cost of LED tube T5 and T8 with isolation power is not high, the non-isolated is generally more mainstream, the volume can be smaller, the minimum height is 8 mm.

4, power efficiency of LED fluorescent lamp

Output power (output LED voltage * Output current / input power). This parameter is particularly important，low inefficient means a large amount of the input power is converted into heat; If the power supply is installed in the lamp，which will produce a very high temperature, the temperature will be higher superposed. And the lifespan of electronic components inside the LED tube T5 and T8 will be shortened with increasing temperature. So efficiency is the most fundamental factor, deciding the life，the efficiency can not be too low, or the heat generated by power in too much.

5, power of LED tube T5 and T8

Height is the main limiting factor, the power generally used for T5 tube / T8 can not be too highly, which is ≤ 9 mm.Browsing http://www.lead-lighting.com/led-tube/t5-tube-smd-3014-series.htm for more information about LED tube T5.

What are the three key factors affecting the price of LED lighting products

1, the domestic enterprises without core technology

The vast majority of core patents of LED upstream industry lies in the hands of foreigners, China mainland lighting companies specializing in commercial LED lighting including RGB LED flood light and household LED lighting have not mastered the core technology, although the manufacturing capacity and share of China’s RGB LED flood light and other commercial and industrial and household LED lighting application products nearly account for 50% in the world, yet it does at least profits.

The main cost of RGB LED flood light and other commercial and outdoor  and indoor LED lighting mainly lies in LED chip, as long as chip prices decline, The price of LED lumen unit can be reduced considerably with that of energy-saving lamps. Because the LED chip uses larger wafers while the production process and the number are growing, which will continue to reduce costs, the lower rate is 20% annually in recent years, the decline in the price include the enhancing efficiency of LED chip, for the better product at the same price，there is still a great price cut for the LED chip.

    

2, it is difficult to dissipate heat for LED RGB LED flood light and other commercial and industrial and household LED lighting application

The effective cooling design is very simple to maintain the 5% cooling cost, there are always two directions: First, the shorter the path of LED chip and the heat sink, the better the thermal design; Second, heat resistance , that is to have enough heat spread path while must also have sufficient “cooling path.” The main cost of this part is structure, which accounts about 20% of the  cost of luminaire，and there is not much costs for cooling. The biggest problem now is how to design more creatively and more reasonable RGB LED flood light and other commercial and industrial and household LED lighting.

3, LED power supply applications

Power is weakest link of led lighting, which restricts the development of LED lighting. The costs of design account for about 20% of that of RGB LED flood light and other commercial and industrial and household LED lighting now, with the technology development of power，about 5-10% cost is the most reasonable.

The cost of RGB LED flood light and other commercial and outdoor and indoor LED lighting is not high contrast with other lighting source，in fact, especially LED lighting is known as environmental protection, energy saving, no mercury, and the price of LED lighting are sliding down at every quarter, The price of RGB LED flood light and other commercial and industrial and household LED lighting will be able to reach an acceptable level of people in a relatively short period of time.Browsing http://www.lead-lighting.com/led-flood-light/led-flood-light-rgb-series.htm for more information about RGB LED flood light.
