The unit price of 1W white LED is 8 ~ 10 yuan, and the unit price of 3W white LED is 20 ~ 25 yuan (related to the quality and brand of LED), and the driving circuit and structural parts are also required. Considering the profit of the manufacturer and commercial profit, the unit price may be more than 120 yuan. The promotion and popularization of white LED lighting is of great significance, but there is still a lot of work to be done in our country. The promotion and popularization of white LED lighting is a systematic engineering and major project, which needs national planning, guidance and support, as well as policy and economic support. What’s more, using sensors, leds have the ability to “feel” and adjust their brightness according to their surroundings.
