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...

AI Technical Summary

Problems solved by technology

Due to the uneven distribution of light intensity in the irradiation area and irradiation range of existing LED lamps, especially the weak light intensity around the lamp, and the low light output efficiency, it is achieved by increasing the density of lamps in the direction parallel to the road. Lighting requirements, the denser the lamps are set, the higher the cost

It is also prone to high illuminance directly under the lamps and low illuminance in other areas, resulting in low average illuminance and poor uniformity on the road surface. This uneven lighting directly affects driving safety

In the existing LED lamps, radiators, circuit boards, light-transmitting mirrors and controllers are installed in the frame in the form of modules. The installation is messy, the process is complicated, the heat dissipation effect is poor, the service life of the lamps is low, and the strength of the frame is required. high, high cost
