Communications and energy measurement is the key to intelligent lighting systems

  • PDF

How LED will play its enormous potential ? Undoubtedly, the first hurdle is price. LED current cost is much higher than existing lighting solutions. Saving often enough to convince price-sensitive businesses and consumers to buy more expensive products. Over time, large-scale production may reduce the price , but the cost is able to drop low enough price to satisfy user expectations of speed ? These are uncertainties , questionable . Of course, these problems are beyond the scope of this article. If we just find two hardware stores, try looking for the same LED lights , which may be very difficult. Many retailers are not just to attract consumers with sparse enough variety or number of stocks , and why ? This relates to price and inventory turns . So this case for those of us engineers, innovators concerned, what does it mean ? How do we make LED lighting their potential ? How to win this marathon victory ?

If we give LED " head" , so intelligent, these lights mounted on the eyes , throat and counting . In the field of lighting design valuable semiconductor materials that will optimize energy efficiency and prolong the life of the lighting and reduce maintenance costs. This will help LED finish the entire race , stick to the end , with the wisdom to win the game .

Ambient light detection , communication and power measurement is a key element of the intelligent lighting system. By ambient light detection, you can dim the lights in the other light sources have provided ample illumination ; Also, by detecting ambient light color , it is possible to adjust the color RGB LED lighting system advanced . Communication function allows remote control and small and large lighting device is connected to a central network . Measuring accurately calculate the energy consumption of the power system to provide insight into predictive maintenance . All of these features - ambient light sensing , communications, energy measurement - will further save energy and reduce operating costs. This article explores the LED lighting system to increase the ambient light detection , communications ( including wireless and powerline ) and energy measurement function key design considerations. Provides a reference design example .

Ambient light sensor (ALS) in the vicinity of the sensor detecting the amount of light . These simple devices LED lighting systems become the "eyes ", is the key to saving energy . When the room has plenty of light, completely unnecessary lighting , lighting can be dimmed or completely shut down , reducing power consumption and extend the lamp life. Key features of ALS include power, lumen scope of monitoring , as well as IR and UV filters . These sensors must stay quiet system , you can not consume too much energy, thereby undermining the system energy savings in mind. ALS consumption good flow reached 1μA or less. Typical detection range must reach the lumen lumen range outdoor environments. 0.1lx to 100,000 lx generally meet most application requirements. Taking into account the reliability of the system , it may be necessary to use a slightly larger range. IR and UV filter system does not actually eliminate the visible spectrum.
