Description

technical field

[0001] The invention relates to the field of lighting equipment, in particular to a street lamp with a light-emitting diode light source. Background technique

[0002] With the construction of urbanization, street lamps can be seen everywhere. Street lighting not only accelerates the pace of urbanization, but also promotes the rapid development of municipal construction. As a window of urban image, landscape lighting, road lighting construction and management have also achieved unprecedented development. Street lights provide a safe and orderly environment for residents to travel at night.

[0003] Compared with traditional street lights, LED street lights not only have the advantages of good chromaticity, maintenance-free, and long life, but more importantly, they are more energy-efficient than traditional street lights. At present, the light-emitting diode light source and power driver of LED street lamps are mostly separated, and some of them are driven ...
