The improvement of the solar energy LED lighting
The rapid improvement of the efficiency of solar energy led lighting and led street light is not only the seeds but also grace
US government regulate to ban 100W incandescent compact fluorescent lamps in 2012. But people want to know that the only reasons for using compact fluorescent. Consumers do not completely change.
In fact, because of all kinds of reasons, a large percentage of consumers have rejected the compact fluorescent lamps, these reasons include flashing lights, color rendering, reliability and cost comparison, the slow start. The small fluorescent light on these issues have been resolved, but in the eyes of many consumers , small fluorescent light is not they wanted. The short term, if used 100W incandescent lamps are burned, many of these consumers will switch to the halogen incandescent lamp.
This will pose a problem: solar energy led lighting can enter the neutral and the consumer will choose the options? So far, there is no commercially available LED lamps to replace the 100W A19 incandescent. The reason is that the passive cooling 1500lm(100W typical lighting the lamp output) LED is still not on the output in the physical level.
The white LED is a very efficient light source, about one-third of the input power is converted to light, the remaining two-thirds of the power is converted to LED in the heat. So 100lm / W, or about 100W power must be continuous and quickly consumed. If the heat has not been removed, the LED lamp will quickly heat up to 120 ¡æ of the maximum working temperature.
This problem may eventually be resolved through the LED luminous efficiency. Last year, the best of cool white LED obtained the lighting efficiency of 100lm / W. This year, a lots of white solar energy led lighting get the efficiency of 120 ~ 130lm / W range. This trend in the foreseeable future will not be decayed.
With the improvement of LED high bay conversion efficiency, the thermal management of improvement is about the square of the efficiency. Because the total power of LED power supply is decreased and the percentage of heat generated by the input power also reduce the number of the corresponding.
