Rapid replacing structure for spreading film of LED lamp

Abstract

A rapid replacing structure for a spreading film of an LED lamp is characterized by comprising a spreading film module and a front cover of the lamp, wherein the spreading film module and the front cover of the lamp are assembled in a covering fitting manner; the spreading film module comprises an upper cover assembly of the spreading film, the spreading film and a spreading film pressing plate; the spreading film and the spreading pressing plate are sequentially fixed to the upper cover assembly of the spreading; the upper cover assembly of the spreading film comprises a pushing button assembly and an upper cover of the spreading film; and the pushing button assembly is mounted into a groove in one side of the upper cover of the spreading film and is capable of elastically pushing in theupper cover of the spreading. According to the rapid replacing structure for the spreading film of the LED lamp; the spreading film module and the front cover of the lamp are not fixed through a screw; and the spreading film module can be integrally clamped and removed from the front cover of the lamp through the pushing button assembly.

Description

technical field [0001] The invention belongs to the field of stage and landscape lamps, in particular to the field of LED lamp diffusion film replacement structure. Background technique [0002] Diffusion film has the function of light diffusion. It is a film material that can promote the uniformity of light brightness. At present, it is more and more widely used in the field of LED lamps. By using different angles of diffusion film, different lighting effects can be presented; different angles of diffusion The use of the membrane requires the replacement of the diffusion membrane, so how to design a more beautiful, faster, and more convenient after-sales diffusion membrane replacement structure is a problem that needs to be solved at present. [0003] In the current published patent literature, the following types of diffusion membrane replacement structures are found: [0004] 1> It is mentioned in the patent document lamp with the publication number CN207741019U that ...

Problems solved by technology

"It can be seen from the above that the dot-shaped protrusions and round holes are used to match the structure, which is invisible in appearance. However, when disassembling, when the plug is moved by hand, the force on the plug is only when the plug is pressed by hand. The side on the opposite side is not stressed, and the plug at the spring end often moves, but the dot-shaped raised part does not move or the displacement is very small, that is, the plug is in a tilted state, resulting in The dot-shaped protrusion is still stuck in the round hole, and the entire replacement structure is invalid. It is often stuck and cannot be replaced in actual use.
