Description

Technical Field

[0001] This utility model relates to the field of lighting technology, and in particular to a high-sealing floodlight. Background Technology

[0002] A floodlight is a lighting fixture designed to provide illumination on a surface higher than the surrounding environment. It is also known as a spotlight. Typically, it can be aimed in any direction and has a structure unaffected by weather conditions. It is mainly used for large-area work sites, building outlines, stadiums, overpasses, monuments, parks, and flower beds. Therefore, almost all large-area outdoor lighting fixtures can be considered floodlights.

[0003] Floodlights typically consist of a housing, a panel, and a shade. Since floodlights are usually installed outdoors, they need to have good waterproof performance and ensure a tight seal between the housing and the shade. However, existing floodlights have poor sealing performance, allowing rainwater to enter the housing through gaps at the edges between the housing and the shade, or at the gaps at the connecting bolts, thus affecting the lifespan of the panel.

[0039] The beneficial effects of this utility model are as follows: the setting of the first sealing ring 400 and the second sealing ring 500 greatly improves the sealing performance between the lamp housing 100 and the lamp cover 300, which can prevent rainwater from entering through the gap at the edge between the lamp housing 100 and the lamp cover 300, and also prevent rainwater from entering the lamp housing 100 through the gap at the fastening bolt, which is conducive to improving the service life of the lamp board 200.

[0040] Please refer to Figure 3 In one possible implementation, a limiting groove 301 is provided on the lampshade 300, and the first sealing ring 400 is disposed within the limiting groove 301. It should be noted that the limiting groove 301 is provided along the four edges of the lampshade 300, and the limiting groove 301 can limit the first sealing ring 400 to improve the stability of the first sealing ring 400.

[0041] Please refer to Figure 3 In one possible implementation, a positioning stud 302 is provided in the middle of the lampshade 300, and the lower end of the positioning stud 302 abuts against the second sealing ring 500. It should be noted that the fastening bolt passes through the lampshade 300 and is fixedly connected to the lamp housing 100 through the positioning stud 302, and the fastening bolt is embedded within the positioning stud 302. Furthermore, the lower end of the positioning stud 302 protrudes from the inner surface of the lampshade 300, thereby making the positioning stud 302 and the second sealing ring 500 fit more tightly, thus improving the sealing performance between the positioning stud 302 and the second sealing ring 500.

[0042] Please refer to Figure 4 In one possible implementation, a plurality of heat dissipation fins 102 are evenly spaced on the back of the lamp housing 100. It should be noted that the heat dissipation fins 102 can improve the heat dissipation efficiency of the light-emitting module, and the heat dissipation fins 102 and the housing are an integral structure. Both the housing and the heat dissipation fins 102 are made of die-cast aluminum alloy, which has good heat dissipation performance and structural strength, and can further enhance the heat dissipation effect.

[0043] Please refer to Figure 2 and Figure 3 In one possible implementation, the lampshade 300 has multiple focusing slots 303 arranged in an array, and the lamp board 200 has multiple LED beads 202 arranged in an array, with each LED bead 202 corresponding to one of the focusing slots 303. It should be noted that the lamp board 200 is a PCB board, the LED beads 202 are LED beads, and the focusing slots 303 can focus the light on the LED beads 202, thereby increasing their brightness.

[0044] Please refer to Figure 1In one possible implementation, a mounting bracket 600 is also included, which is fixedly connected to the back of the lamp housing 100.
