Description

Technical Field

[0001] The utility model relates to the technical field of lamp boards of LED light sources, in particular to a lamp board fixing structure of an LED light source. Background Art

[0002] LED lighting products have become widespread, and cost competition is fierce. Housings are made of various materials, including plastic-coated aluminum, all-plastic, die-cast, glass, and profile processing. Due to cost constraints, low-power LED light sources are increasingly using all-plastic lamp bodies. For example, application number 201220694392.2 describes an embedded LED plastic-shell downlight. This all-plastic lamp body has the disadvantages of being easily deformed and having poor dimensional stability. Conventional lamp panels utilize a circular design around the periphery, secured to the all-plastic lamp body through an interference fit. This friction-based fixation method, which relies on an interference fit at the edges, is prone to falling off when subjected to mechanical vibration, necessitating additional assembly processes to address the problem of falling off between the lamp cup and the lamp panel. For example, auxiliary processes such as gluing and screwing are used to secure the lamp panel and body together.

[0003] Therefore, the utility model designs a lamp board fixing structure of an LED light source, which can effectively solve the problem of falling off between the lamp cup and the lamp board without adding additional processes. Utility Model Content

[0004] In response to the shortcomings of the existing technology, the purpose of the present utility model is to provide a lamp board fixing structure for an LED light source. The fixing structure changes the outer contour of the lamp board, and the outer periphery of the lamp board has a serrated structure. When the lamp board body and the inner cavity of the lamp body are interference fit, the serrated structure presses against the inner cavity wall of the lamp body, so that the lamp board and the inner cavity of the lamp body are firmly assembled and not easy to fall off, thereby effectively solving the problem of falling off between the lamp cup and the lamp board.

[0005] In order to achieve the above purpose, the present invention provides the following technical solutions:

[0006] A lamp board fixing structure for an LED light source includes a lamp board main body. A serration structure extending outward is provided on the circumference of the lamp board main body so that when the lamp board main body is interference-fitted with the inner cavity of the lamp body, the serration structure pierces the inner cavity wall of the lamp body.

[0007] Preferably, the sawtooth structure includes several groups of sawteeth, and the distance from each group of sawteeth to the center of the lamp board is greater than the radius of the lamp body.

[0008] Preferably, the plurality of groups of saw teeth are distributed at equal intervals along the circumference of the main body of the light panel.

[0009] Compared with the prior art, the beneficial effects of the present invention are:

[0010] (1) This fixing structure changes the outer contour of the lamp panel, and the outer periphery of the lamp panel is serrated. When the main body of the lamp panel is interference-fitted with the inner cavity of the lamp body, the serrated structure presses against the inner cavity wall of the lamp body, so that the lamp panel and the inner cavity of the lamp body are firmly assembled and not easy to fall off, thereby effectively solving the problem of falling off between the lamp cup and the lamp panel.

[0011] (2) This product does not require any additional processes, is easy to produce, and has a price advantage. BRIEF DESCRIPTION OF THE DRAWINGS

The lamp panel body 1 is interference-fitted with the inner cavity of the lamp body 2. Existing LED light sources have the problem of the lamp cup and the lamp panel falling off. Therefore, the lamp panel fixing structure of the LED light source designed in this invention changes the outer contour of the lamp panel, and the outer periphery of the lamp panel has a serrated structure. When the lamp panel body and the inner cavity of the lamp body are interference-fitted, the serrated structure pierces the inner cavity wall of the lamp body, so that the lamp panel and the inner cavity of the lamp body are firmly assembled and not easy to fall off, thereby effectively solving the problem of the lamp cup and the lamp panel falling off.
