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 ...

Abstract

The invention discloses a LED tunnel light. It includes shell and lighting module. The former includes lamp body fixed structure. The latter includes lens shade formed by lens array which formed by astigmatism convex and condense edge. The astigmatism includes light incidence and emergent planes. The lamp body fixed structure includes fixed frame and fixed plated surface. The invention can control the light distribution to make faculae form rectangle, have even illumination in effective area, little or no parasitic light out the area.

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, ...
