1. Single LED has low power. In order to obtain high power, multiple parallel connections are required.
2. Low color rendering. The color displayed under the illumination of LED is not as real as that of incandescent lamp, which is a technical problem to analyze from the spectral distribution.
3. Flare. Due to the manufacturing process defects of white LED itself and the matching error with the reflector cup or lens, it is easy to cause the "yellow circle" problem.
4. LED illumination uniformity. If the secondary optical design is not carried out, the illumination of LED is relatively concentrated, so the secondary optical design must be carried out to make the light intensity distribution diagram look like a bat.
5. Light failure of LED. Compared with low-power LED, high-power LED street lamps will have much better light attenuation. However, the heat emission of low-power LED is very small. However, high-power LED has a problem that cannot be solved by cooling, and its brightness will be significantly reduced after heating, so the power cannot be increased. The largest Spark LED street lamp sold in the market is 360W.
