Description

technical field

[0001] The invention belongs to the field of LED lighting and relates to an LED tunnel lamp. Background technique

[0002] Traditional tunnel lighting lamps mainly use sodium lamps, mercury lamps or metal halide lamps, but these lamps consume a lot of power, have a short lifespan, and have high maintenance costs, which are not conducive to environmental protection. Therefore, the use of LED lamps to replace traditional lamps has become a revolution in the field of lighting.

[0003] LED tunnel lights usually cover the LED with a lens to collect light, but the existing lens projects a circular light spot, and the light intensity difference between the center and the periphery is large; in addition, for some In the occasions where large-scale lighting is required in one direction, but small-scale lighting is required in another direction, such as road lighting, a wide range of illumination is required in the direction of road extension, good lighting effects, ...
