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, ...

Examples

Embodiment Construction

[0030] The invention provides an LED tunnel light. The tunnel light includes a housing and at least one lighting module mounted on the housing. The casing includes a lamp body fixing structure; the lighting module includes a lens covered on the LED lamp. The lens includes a pillow-shaped astigmatism protrusion located in the middle of the lens and light-gathering edges located on both sides of the astigmatism protrusion. The astigmatism protrusion includes a light incident surface on the inner wall surface and a light exit surface on the outer wall surface. The lamp body fixing structure includes a fixing frame and a fixing plate surface of the LED lamp housing. In order to have good light extraction efficiency and light output angle, the present invention optimizes the light-gathering edge so that the light-gathering edge is in the shape of a raised peak.

[0031] The preferred mode of the present invention is: the inner side of the astigmatism protrusion is provided with ...
