Description

1. Technical field:

[0001] The invention relates to the field of LED lighting, in particular to an LED street lamp. 2. Background technology:

[0002] Existing street lamps use mercury lamps, sodium lamps, metal halide lamps or energy-saving lamps, and their energy comes from 220v alternating current, which not only consumes a lot of power, but also has a short service life and high maintenance costs, which is not conducive to energy saving and environmental protection . Therefore, replacing traditional lamps with LED lamps has become a revolution in the field of lighting.

[0003] Existing LED street lamps are generally formed by arranging multiple LEDs on a circuit board, and then setting a plane light-transmitting mirror on the outside. The irradiation area of ​​each LED is a circular spot, and the light intensity between the center and the periphery The difference is large, even after passing through the plane light-transmitting mirror, the original illumination method...
