Problems solved by technology

[0002] Existing LED lamp panels generally adopt direct lighting, which is prone to glare and insufficient uniformity. In order to better dissipate heat, stripes or waves are added to the outer surface of the aluminum frame, which seriously affects the appearance, especially at the corners. Lots of flash, easy to scratch hands and poor consistency

Embodiment Construction

[0023] The LED lamp panel of the present invention will be described in further detail below in conjunction with specific embodiments and drawings.

[0024] Such as Figure 1 to Figure 8 As shown, in a preferred embodiment, the LED lamp panel of the present invention mainly includes a substantially square frame 9 and a bottom cover 5, a reflective sheet 19, a light guide plate 7 and a diffusion plate 8 fixed in the frame 9 in sequence. At least one (two in this embodiment) elongated LED light bar 11 is arranged on the side of the light guide plate 7 and fixed inside the frame 9.

[0025] Please also refer to image 3 , The frame 9 is composed of four sides. Each side includes a substrate 91 that is substantially parallel to the diffuser plate 8 and a first wall 93 extending from the back of the substrate 91 (herein, the back refers to the side facing away from the direction of the LED lamp panel) substantially perpendicular to the substrate. And the second wall 92. The first wal...

Abstract

The invention relates to a light emitting diode (LED) lamp disk which comprises a frame, a bottom cover, a reflection sheet, a light guide plate and a diffusion plate, wherein the bottom cover, the reflection sheet, the light guide plate and the diffusion plate are sequentially fixed in the frame. At least one strip-shaped LED lamp bar is arranged on the side edge of the light guide plate and fixed on the inner side of the frame. The LED lamp disk is characterized in that the frame comprises a base plate generally parallel to the diffusion plate and a first wall and a second wall, wherein the first wall and the second wall integrally extend out from the back of the base plate and are generally perpendicular to the base plate. The first wall and the second wall are parallel, a platform for accommodating at least the edge of the diffusion plate is formed between the edge of the base plate close to the center of the LED lamp disk and the second wall, the LED lamp bar is fixed on the second wall, and opposite surfaces of the first wall and the second wall are wave-shaped. The LED lamp disk adopts a side entering type, utilizes the light guide plate to generate an even lighting surface, raised grains are not arranged on the outer surface of the frame, and the LED lamp disk is attractive in appearance, small in corner trimming and strong in consistency. The raised grains are arranged on the inner surface of the frame, and heat dissipation of the frame can be guaranteed.

Description

Technical field [0001] The invention relates to an LED lamp panel. Background technique [0002] The existing LED lamp panels are generally direct-lit, which is prone to glare and insufficient uniformity. In order to better heat dissipation, stripes or waves are added to the outer surface of the aluminum frame, which seriously affects the appearance, especially at the corners. There are many flashes, easy to scratch the hands and poor consistency. Summary of the invention [0003] The purpose of the present invention is to provide an LED lamp panel that is not easy to produce glare, good heat dissipation and smooth appearance. [0004] An LED lamp panel includes a frame and a bottom cover, a reflective sheet, a light guide plate and a diffuser which are sequentially fixed in the frame. At least one elongated LED light bar is arranged on the side of the light guide plate and fixed inside the frame. The frame includes a substrate arranged substantially parallel to the diffuser plat...
