Abstract

The invention relates to a light guide plate type ceiling lamp with a backlight source, and the lamp comprises a ceiling disc, wherein an accommodating hole is formed in the lower end of the ceiling disc; a coupling connection terminal and a driver which are arranged in the accommodating hole; a base disc, wherein a convex ring is arranged at the upper end of the base disc; a counter bore which isformed in the lower end of the base disc; a middle hole, wherein two ends of the middle hole are respectively communicated with the counter bores and the inner holes of the convex ring in a one-to-one correspondence manner; a backlight source which is disposed at an outer side of the convex ring; a light transmitting ring which covers the backlight source and is detachably connected with the basedisc; light-reflecting paper which is connected with the upper end of the counter bore; a main light source which is arranged on the side wall of the counter bore; a light guide plate and a diffusionplate which are sequentially positioned on the lower side of the main light source and are respectively connected with the side wall of the counter bore; a light-transmitting cover which covers the diffusion plate and is detachably connected with the base disc, wherein the ceiling disc is located in an inner hole of the convex ring and detachably connected with the base disc. The light guide plate type ceiling lamp with the backlight source is provided with the backlight source, a warm atmosphere can be created for a manufacturing scene, assembling, disassembling and maintaining are convenient, emitted light is soft and uniform, and the size of the ceiling lamp is small.

Description

technical field [0001] The invention relates to the technical field of LED lamps, in particular to a light guide plate type ceiling lamp with a backlight source. Background technique [0002] The invention of Chinese patent application number: 201910969562.X discloses a ceiling lamp, including a chassis, a frame assembly and an assembly assembly; the chassis has a bonding surface for bonding to the ceiling, and the frame assembly is vertically aligned with the chassis through the assembly assembly Detachable connection. The traditional ceiling lamp has the disadvantages of not having a backlight source, which is not conducive to creating a warm atmosphere, disassembly and maintenance is not convenient enough, the light is dazzling and not uniform enough, and the ceiling lamp is thicker. Therefore, it is necessary to design a backlight that is conducive to creating a warm atmosphere. , Easy to assemble and disassemble and maintain, soft and uniform light output, and light gu...
