The unique LED earrings

Want to be the most dazzling queen in the party? An engineer named Bertho Stoltiens shared his shiny earrings Blinkring, The earrings have a diameter of about 31mm eardrop，the total number of 12 LED were set in a circle above. This concept of the earrings is based on standard Cr2032 button-type battery with a slightly larger circular printed circuit board (PCB), the operation of the LED parts required is a small circle on the board outside the battery.

Stoltiens came across a number of challenges when carrying out the design case，because he did not have to think a method of boosting the battery appearance, but also installing a switch, so that the wearer can easily operate. Clamp-like battery holder is made of a paperclip, Stoltiens said the very small arc on the battery holder can provide sufficient spring effect to make the battery and battery holder close bonding; other side of the circuit board is the user interface to switch , as which the paperclip structure was used, both sides seem very elegant shape.

Stoltiens said in his personal blog that the existing switching device will be used as the next version of the earring design. It is a very hard to build up the Switch light adopted now.

In addition to the challenges of the physical PCB architecture, Stoltiens also encountered some difficulties in chip programming; the Microchip's PIC12LF1552 microcontroller is used，which can not be programmed by Blinkring’s PICKit2 tools being used，the next step may be carried out by using PICKit2 Device Data File Editor . There is also a problem, PIC12LF1552 has no standard ISP head for programming.

Stoltiens thought a very simple solution that is five contacts were added on the back of the PCB and made a customized programming dock (dock), the earrings can be held when needing to be updated. The spacing is 100mi on the PCB pad (pad) , therefore by using the contacts on the vertoboard be used as the programming base.

Blinkring circuit board programming method

The LED was distributed in six points on the earrings, each point has red and green LED; Stoltiens was originally hoping to achieve the unity brightness through hardware method, but finally using the software to make LED glow to reach a satisfactory. The method adopted is to maintain that the shiny time of the green LED light is twice longer than of the red .

There are several kinds of LED light mode for the earrings, just press the switch button can be switched; And the LED light can’t be turn off until you push the button for long time, and then gently press once to start. Stoltiens expressed, Blinkring battery life can reach 100 to 200 hours, while you can sustain more than 1 year if in the sleep state.

LED lighting is designed in the earrings, which is a particularly novel and unique method that can add highlights for many ladies to make them become the focus of attention，apparently LED lighting is closely connected to design to bring us the extraordinary experience and unique enjoyment. Nowadays, LED light is to provide daily lighting, along with the popularity of LED lighting, its design will be updated to enter our lives, the LED flood light and LED tube light represent the outdoor decorative lighting and indoor lighting,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 need higher brightness lighting to illuminate, 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 LED tube light  and LED flood light use low voltage constant current driver, which current the alternating into direct current so that improve energy efficiency and reduce the waste heat energy and stroboscopic effect excite 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.
