Summary:
1. At present, the power of a single LED street lamp is low. In order to obtain high power, multiple parallel connections are required.
2. Low color
1. At present, the power of a single LED street lamp is low. In order to obtain high power, multiple parallel connections are required.
2. Low color rendering rate. The color displayed under the illumination of LED street lamp is not as true as that of incandescent lamp, which needs to be analyzed from the spectral distribution, which is a technical problem.
3. Is the light spot. Due to defects in the manufacturing process of the white LED street lamp itself and the matching error with the reflector or lens, it is easy to cause the yellow circle problem.
4. The uniformity of light-emitting diode street lamp illumination. If the secondary optical design is not carried out, the light-emitting diodes are relatively concentrated, and the secondary optical design must be carried out to make the light intensity distribution map look like a bat.
5. The light attenuation of current LED street lamps. Compared with low-power LEDs, the light attenuation of high-power LED street lamps is much better. However, low-power light-emitting diodes emit very little heat. In addition, high-power light-emitting diodes have problems that cannot be solved by heat dissipation, and the brightness will be significantly reduced after heating, so the power cannot be increased. At present, the largest Spark LED street lamp sold on the market is 360W.
