       low  LED Street Light   is not only power, also known as the "green light." LED semiconductor lighting technology is developing rapidly in recent years, compared with traditional lighting sources, it has numerous advantages, such as long life, small size, green, more good modulation performance, response and high sensitivity.          LED using this feature can be used for illumination, it is also possible to modulate the signal to the LED visible light beam for data transmission, to achieve a new kind of optical wireless communication technology. Optical communication is a communication with the carrier wave, i.e., a baseband signal with light modulation. Select power street light led street light, street light supports supporting the PWM dimming input drive power. Optical communications controller directly from Shenzhen single light controller, which supports PWM dimming output, LED Lights can be collected in real time voltage, current, active power, power factor, temperature and other real-time status data.          Visible light communication at home and abroad and is still in the initial exploratory stage, but its prospects are very promising. By using the appropriate modulation and demodulation techniques, borrowed from the existing technology and equipment conditions, quickly verify the feasibility of led street light to achieve visible light communication and optical communication accomplished through real-time data transmission LED lights work for the state, as Streetlights intelligent management provides a new way of thinking and reference. The same time as technology advances and optimization solutions, LED lights will realize the significance of optical communications is not limited to this, it would completely subvert the value of the original definition of lights, street lights will not be limited to the provision of road lighting functions, and will serve as an all over communication access point of the city exists to provide new direction and impetus to the development of intelligent transportation, realize the wisdom of the city, this longing to believe all expectations in the near future will certainly be achieved.
