Description

Technical Field

[0001] The utility model relates to the technical field of floodlights, in particular to a replaceable floodlight luminous component. Background Art

[0002] A floodlight is a lamp with a higher illumination on the designated illuminated surface than the surrounding environment. Usually, it can be aimed in any direction and has a structure that is not affected by climatic conditions. It is mainly used in large-area work sites and mines, building outlines, stadiums, overpasses, monuments, parks and flower beds, etc. Therefore, almost all large-area lighting fixtures used outdoors can be regarded as floodlights.

[0003] The existing protective cover of the floodlight is usually fixed to the lamp housing by screws or expansion bolts. Such an installation process is relatively complicated and it is inconvenient to disassemble and assemble the light source, which brings great inconvenience to the user.

[0004] In order to facilitate the disassembly and assembly of the protective cover, after searching, a utility model patent with announcement number CN215411542U in the prior art is found, which discloses a floodlight with easy light source replacement, including a lamp housing, a retaining ring is provided on the inner side of the lamp housing, a protective cover is provided on the surface of the retaining ring, a receiving groove is opened on the inner side of the lamp housing, a sealing gasket is provided on the receiving groove, and a fixed structure with a buffer function is provided on the side of the lamp housing, the fixed structure includes a mounting seat, and a fixed shaft is provided between the two mounting seats.

[0005] The above-mentioned prior art can press the edge of the protective cover through a pressing block during use, so that the protective cover is pressed onto the retaining ring, and the limiting assembly fixes the rotating block to achieve fixed installation between the protective cover and the lamp housing. The operation is simple and convenient for disassembly and assembly of the light source. However, the pressing plate is pressed onto the surface of the protective cover under the action of the first spring. When the lamp housing is subjected to strong vibration, the protective cover will have the risk of overcoming the elastic force of the first spring and escaping from the retaining ring, thereby affecting the stability of the floodlight during use. Therefore, we propose a replaceable floodlight light-emitting component. Utility Model Content
