What are the 6 main disadvantages of LED street lights? What are the 6 major disadvantages?
Light LEDAfter a period of illumination, the light intensity of LED will be lower than that of the original light
Compared to small power LED, high power LED lamp light will be much better.But small power LED emits little heat. And high-power LED is the problem of heat dissipation can not solve, and after heating brightness will be significantly reduced, so power can not be bigger.
LED irradiation uniformity problemIf we do not carry out the two optical design, the illumination of LED lighting products is relatively concentrated, so we must carry out two optical design, so that the light intensity distribution pattern is bat shaped.
Facula。Because of the defect of the manufacturing process of white LED, and the matching error with the reflecting cup or lens, it is easy to cause the "yellow circle" problem.
1 single LED power low. In order to obtain high power, more than one parallel connection is needed.TwoLow color rendering index.It is a technical problem that the color displayed by LED radiation is not true of incandescent lamp, and it should be analyzed from the spectral distribution.
