Embodiment

[0037] The present invention is a side-entry LED curved panel light structure. The curved surface can be a cylindrical surface, a spherical surface, etc., or even a cylindrical surface plus a spherical surface. The surface type can be specially designed according to the lighting area and shape.

[0038] Its structure is as Image 6 As shown, 18 is an aluminum substrate on which other components of the panel light can be installed, 19 is an LED lamp bead, nested in a compressed beam aluminum clip, 20 is a high-reflection paper, and 21 is acrylic with good light transmittance Light guide plate, 22 is diffuser plate and lampshade, and 23 is the light of total reflection. The concave and convex surface of the light guide plate is designed with inward convex points. When the light hits the convex points, the total reflection condition of the light is destroyed, part of the light is transmitted out, and part of the light enters the bottom of the panel. The high reflective paper or h...

Abstract

The invention discloses a side-in type LED curved plate lamp structure which comprises a side-in type LED with an aluminum clamping piece, a curved concave-convex surface and a light guide plate with convex points, wherein the aluminum clamping piece can compress an LED beam from 120 degrees to 40 degrees. The invention further discloses a relational expression of the curvature radius of the light guide plate and the thickness of the light guide plate, and forming the convex points on the light guide plate is a result of ray tracing which uses light rays with small angles to set convex points in the distance and uses light rays with large angles to set convex points nearby, so as to ensure uniform distribution of light intensity and maximum utilization of light energy.

Description

technical field [0001] The invention relates to LED light-emitting panel technology, in particular to a structure of a side-entry curved LED panel light. Background technique [0002] LED has the advantages of small size, low voltage direct current, environmental protection, long life, high color rendering, etc., and has broad application prospects in the field of lighting. In recent years, LED solid-state lighting technology has developed rapidly, especially panel lighting, because of its large light-emitting area, soft light, and no glare, it is rapidly replacing incandescent lamps in indoor lighting applications. [0003] Panel lights need LED modules as light sources. From the way of LED light source introduction, there are two types: direct type and side type. The top view of the flat panel light is as follows figure 1 As shown, there are only 2 aluminum shells and 1 flat light-emitting panel seen from the outside. Because it is a straight-down type, the lamp is rela...
