A led panel light

Abstract

The invention relates to an LED panel light, which includes an LED lamp board, a light guide layer and a uniform light layer. The LED lamp board includes a substrate and side-emitting LED lamp beads on the substrate, and the uniform light layer and the light guide layer are integrated through a co-extrusion process. structure, and extrude upward side grooves on at least one side of the light uniform layer, the LED lamp board is placed flat in the side grooves, and the light emitting direction of the LED lamp beads faces the light guide layer . The LED panel light provided by the present invention meets the requirements of outdoor waterproof use with a simple structure, and can achieve the effect of uniform light output from the front in a small thickness space, and at the same time improves the performance of dustproof and corrosion resistance.

Description

technical field [0001] The invention relates to the technical field of lighting, in particular to an LED panel light with thinner thickness and good waterproof performance. Background technique [0002] Among the many product series of LED lighting, there is a kind of lamp, because it has a large area of ​​light and no visible direct-viewing light source, and has excellent characteristics of uniform light output, no glare and no ghosting, it is used in places such as hospitals, halls and halls. The use is very common, and this type of light is usually called a panel light or a flat light. [0003] Traditional panel lights are usually made of aluminum extruded or aluminum die-casting structural parts to form the surrounding frame structure of the panel light. The LED light board is placed vertically in the frame structure, and its light distribution is surrounded by uniform light plates, light guide plates, reflective films and metal panels. Around the secondary optical part...

AI Technical Summary

Problems solved by technology

[0004] With such a structure, there are a large number of gaps between the frame of the main structural parts, the uniform light plate, the light guide plate, the reflective film and the metal back plate, etc., which cannot meet the requirements of waterproof and sealing, especially in outdoor or humid indoor working environments. Use requirements, and due to the upright use of the LED light board and the corresponding complex structural relationship, the thickness of the whole light is relatively thick, generally not less than 8mm, it is difficult to apply to the occasions that require a small installation height or a completely embedded installation.
