Description

technical field

[0001] The invention relates to an LED lighting device, in particular to an LED street lamp. Background technique

[0002] Because LED street lamps have the characteristics of long life, high light source, no radiation, and low power consumption, LED semiconductor light sources have been widely used in the lighting field in recent years. In the prior art LED street lamp, the body of the LED street lamp is only provided with one group of LED light-emitting diodes. When the LED street lamp is working, the group of LED light-emitting diodes is lit at the same time. For street lamps, the temperature inside LED street lamps is also relatively high, which affects the service life of each LED light-emitting diode, and the LED light-emitting diodes are also easy to burn out.

[0003] Therefore, there are defects in the prior art and need to be improved. Contents of the invention

[0004] The technical problem to be solved by the present invention is to provide an...
