[0037] like Figures 1 to 3As shown, the embodiment of the present invention provides a photographic lamp for supplementing the light brightness of a photography location. The photographic lamp provided in this embodiment has multiple waterproof designs, which improves the waterproof performance of the photographic lamp. The following is an explanation of the specific implementation method:

[0038] The photographic lighting device of this embodiment includes:

[0039] A shell body 1, a first cover body 2 and a second cover body 3 arranged on the shell body 1, the shell body 1, the first cover body 2 and the second cover body 3 enclose a cavity; a heat dissipation component 4 and a circuit board 5 are provided inside the shell body 1, a light source component through hole 21 and a light source component 22 arranged in the light source component through hole 21 are provided on the first cover body 2, and a light source component cavity 10 is formed between the light source component 22 and the heat dissipation component 4; wherein, a first waterproof structure 23 is provided between the hole wall of the light source component through hole 21 and the light source component 22; a second waterproof structure 24 for sealing the light source component cavity 10 is provided between the light source component 22 and the heat dissipation component 4.

[0041] The first cover body 2 refers to a part of the protective structure used as a photographic lamp. The first cover body 2 is used to cover the shell body 1 so that a cavity can be enclosed between the first cover body 2 and the shell body 1; the first cover body 2 is provided with a light source component through hole 21 and a light source component 22. The shape and size of the light source component through hole 21 match the shape and size of the light source component 22, so that the light source component 22 can be just installed in the light source component through hole 21. There is a gap between the hole wall of the light source component through hole 21 and the light source component 22, so there is a first waterproof structure 23 between the two. The first waterproof structure 23 is used to seal the gap so that the light source component through hole 21 is sealed; the light source component 22 is also used to enclose a light source component cavity 10 with the surface of the heat dissipation component 4. The light source component cavity 10 is communicated with the light source component through hole 21. The light source component 22 extends into the light source component cavity 10 through the light source component through hole 21, that is, the light source component cavity 10 is used to accommodate part of the light source component 22. A second waterproof structure 24 for sealing the light source component cavity 10 is provided between the light source component 22 and the heat dissipation component 4;

[0042] The second cover 3 is a part of the protective structure of the photographic lamp. The second cover 3 is used to cover the shell 1 so that a cavity can be formed between the second cover 3 and the shell 1.

[0043] The waterproof principle of the photographic lighting provided in this embodiment is as follows:

[0044] The photographic lamp includes a shell 1 and a first cover 2 and a second cover 3 provided on the shell 1.

The shape of the portion of the second waterproof structure 24 is columnar, and the second waterproof structure 24 is elastic and is used to seal the light source component cavity through hole 25.

[0059] Here, it can be understood that the light source component cavity through hole 25 is used to install a power cable electrically connected to the light source component 22. The power cable is installed in the light source component cavity through hole 25 and is electrically connected to the light source component 22. A second waterproof structure 24 is provided in the light source component cavity through hole 25. The shape and size of the second waterproof structure 24 match the shape and size of the light source component cavity through hole 25, so that the second waterproof structure 24 can be precisely installed in the light source component cavity through hole 25. The second waterproof structure 24 is elastic, so that the hole wall of the light source component cavity through hole 25 can exert a force on the second waterproof structure 24, causing it to deform, thereby achieving an interference fit between the second waterproof structure 24 and the light source component cavity through hole 25. By adopting the above technical solution, the waterproof performance of the second waterproof structure 24 is further improved.
