Ultra-thin panel lamp for built-in power supply

Abstract

The invention provides an ultra-thin panel lamp for a built-in power supply. The lamp comprises an outer frame, a diffusion plate and a back cover, wherein the outer frame and the diffusion plate are arranged under the back cover; a pearl cotton, reflecting paper and a light guiding plate are sequentially mounted between the back cover and the diffusion plate from top to bottom; an inner end of the outer frame is L-shaped; the diffusion plate is arranged on a transverse surface of an L-shaped inner end of the outer frame; a PCB board is arranged on a vertical surface of the L-shaped inner end of the outer frame; an LED lamp strip is arranged on the PCB board; a luminous surface of the LED lamp strip is irradiated on the side surface of the light guiding plate; a hollow groove is formed in the middle part of the outer frame; a power supply is arranged in the hollow groove; heat conductive glue are filled withe the periphery and bottom of the power supply; and waterproof glue is filled between the power supply and the back cover. When the ultra-thin panel lamp for the built-in power supply disclosed by the invention is used for a long time, good heat radiation effect and waterproof effects can be achieved, so that the service life is prolonged.

Description

technical field [0001] The invention relates to the technical field of lighting, in particular to an ultra-thin panel light with a built-in power supply. Background technique [0002] As the main trend of light source, LED lights are becoming more and more popular and widely used in lighting, outdoor advertising and other fields. Most of the panel lights on the market have external power supplies, and the power supply is exposed in the air, so the installation is easy to drop, or the wiring is not strong, and it may even cause an electric shock hazard. In addition, the external power supply is not conducive to product packaging and transportation, and increases transportation costs. Some power supplies are built-in, which takes up a lot of space, thereby increasing the thickness of the panel light, and the existing built-in power supply panel lights are not waterproof, and the heat dissipation effect is not good. Long-term use will reduce the service life of the power suppl...

AI Technical Summary

Problems solved by technology

Most of the panel lamps in the market have external power supply, and the power supply is exposed in the air, so the installation is easy to fall off, or the wiring is not strong, and it may even cause an electric shock hazard

In addition, the external power supply is not conducive to product packaging and transportation, and increases transportation costs

Some power supplies are built-in, which takes up a lot of space, thereby increasing the thickness of the panel light, and the existing built-in power supply panel lights are not waterproof, and the heat dissipation effect is not good. Long-term use will reduce the service life of the power supply due to moisture. If the power supply If used for a long time, the heat will not be dissipated, which will also cause damage to the power supply. The existing waterproof measures are to install foamed silicone strips in the outer frame. In the case of high temperature, once it is aged, the lamp is no different from the ordinary surface lamp
