Specific implementation

[0023] In order to make the technical means, creation features, purposes and effects realized by the utility model easy to understand, the utility model is further described below in combination with specific drawings.

[0024] Reference Figures 1-4The utility model provides a kind of low-noise high-efficiency heat dissipation's camera light, its outside includes a shell with opening and a panel 2 (translucent material) capable of being installed in shell opening position, shell and panel 2 are enclosed and constitute an internal mounting space, wherein panel 2 has first through-hole 201 for realizing that external atmosphere is communicated with the inside of mounting space, the inside of its camera light includes lamp panel 3 in the inside of mounting space, lamp panel 3 has second through-hole 302 in addition to having luminous element 301 (lamp pearl or lamp sheet), lamp panel 3 divides the inside of mounting space into first space 5 and second space 6, the first space 5 and the second space 6 of mounting space are only communicated by second through-hole 302, the camera light also has an aerodynamic device, mainly for realizing the air interaction inside and outside shell, realizes heat dissipation, specifically can adopt turbine fan 4, turbine fan 4 is used to realize that pressure difference is continuously generated between first space 5 and second space 6, due to the existence of continuous pressure difference, first space 5 and second space 6 will have continuous air flow through second through-hole 302, to realize the heat dissipation of lamp panel 3, the utility model is opened second through-hole 302 on lamp panel 3, can make the air flow of both sides of lamp panel 3, especially for the front of lamp panel 3, it is installed as heat source lamp pearl or lamp sheet, and direct contact with flowing air, and the effect of heat dissipation is better, simultaneously due to the existence of second through-hole 302, air is contacted with the side wall of second through-hole 302, also increase the heat dissipation area of lamp panel 3, further improve the effect of heat dissipation.

[0025] Further, the turbine fan 4 of the utility model is acted on the second space 6, so that pressure difference is generated between the first space 5 and the second space 6, and air flow is promoted in the mounting space. Specifically, the turbine fan 4 can blow air to the second space 6 or extract air in the second space 6, so that the first space 5 and the second space 6 have pressure difference.

[0026] Further, referring to Figure 2 and Figure 3 In the above scheme, a more preferred way is that the turbine fan 4 extracts air in the second space 6. Specifically, the input end of the turbine fan 4 is aligned with the third through-hole 101 on the shell 1. The input end of the turbine fan 4 is in the second space 6, so that the first space 5 and the second space 6 continuously have pressure difference. The air flow direction is as shown in Figure 2The external atmosphere enters the inside of the first space 5 through the first through hole 201 on the panel 2 to radiate the front surface of the lamp panel 3, then due to the existence of the pressure difference, the air in the first space 5 enters the inside of the second space 6 through the second through hole 302 on the lamp panel 3 to radiate the back surface of the lamp panel 3, the air absorbing heat is extracted by the input end of the turbine fan 4, and then is discharged to the external atmosphere through the output end of the turbine fan 4, in the scheme, the turbine fan 4 extracts the air in the second space 6 as a relatively preferred mode, because the external air first absorbs heat through the lamp panel 3 and then contacts the turbine fan 4, better heat radiation of the lamp panel 3 is realized, and if the air blowing mode is adopted, the external air first contacts the turbine fan 4, absorbs the heat of the turbine fan 4, and then contacts the lamp panel 3, so that the heat radiation of the lamp panel 3 is poor.
