Description

LED panel lamp

Technical Field

The invention relates to an LED flat lamp.

Background

The structure of the existing LED flat lamp is as follows: the LED lamp panel comprises a diffusion plate, a light guide plate, a reflective film, EVA sponge and a bottom cover plate which are sequentially arranged from bottom to top, and is provided with two LED lamp strips positioned on two sides of the LED lamp panel or four LED lamp strips positioned around the LED lamp panel; four section bars enclose into a square frame, and the medial surface at square frame is established to the LED lamp strip, and the side top of LED lamp plate supports the LED lamp strip, LED lamp plate and square frame fixed connection, this kind of structure, the light that the LED lamp pearl on the LED lamp plate of side sent is through LED lamp plate leaded light diffusion back, and is all shone downwards. When a larger light-emitting surface is required, the LED lamp with the structure cannot meet the requirement, because the diffusion plate and the light guide plate with the diameter of more than 2 meters are basically not available in the current market, and even if the LED lamp can be manufactured with a huge weight, the LED lamp is difficult to mount after being manufactured into a flat lamp.

Disclosure of Invention

The invention provides an LED flat lamp, which aims to solve the defects of the prior art and enable a large-size LED flat lamp to be possible.

The technical scheme adopted by the invention for solving the technical problems is as follows: an LED flat lamp comprises a shell, an LED light source module, a power supply and a lampshade, wherein an air extractor is arranged on the shell, a plurality of first ventilation holes communicated with a lampshade cabin are uniformly distributed on the side edge of the shell, a second ventilation hole communicated with the lampshade cabin is arranged at the top of the shell, the second ventilation hole is connected with the air extractor, a heat dissipation and air extraction channel is formed by the second ventilation hole, the lampshade and the first ventilation hole, the lampshade is made of a light-transmitting flexible material, the light-transmitting flexible material can be made of textile fabric or plastic film material, a switch valve capable of adjusting the air volume is arranged in the first ventilation hole, filter screens capable of filtering mosquitoes are arranged in the first ventilation hole and the second ventilation hole, filter cotton capable of filtering dust is further arranged in the first ventilation hole, a radar sensing module capable of detecting distance is arranged in the middle position of the top of the shell, and the flexible material is used as the lampshade, the area of all flat lamps can be done very big, and also can splice even the textile material area is not enough, and the area of concatenation department can be done enough little, the weight of the big area lamp shade of like this again can not be very big yet, in addition because flat lamp generally all is hoist and mount and use, certain protruding phenomenon can appear in the middle part of the lamp shade under the great condition of lamp shade area, the air exhaust device that sets up at the lamp body top makes flat lamp during operation lamp shade inner space be in a negative pressure state all the time and offsets the protruding phenomenon because gravity produces, the adjustment of negative pressure volume is adjusted the rotational speed of radar response module according to the deflection adjustment air exhaust device fan of lamp shade by setting up at casing top intermediate position, in addition also can adjust the degree of opening and shutting of the ooff valve that sets up in first ventilation hole.

The invention has the advantages that:

the invention has simple assembly, can realize the light weight of the large-size flat lamp, reduces the installation cost due to the whole weight reduction of the flat lamp, and improves the safety.
