Additionally, it should be noted that for the convenience of description, only the parts of the structure related to the present utility model are shown in the drawings instead of the entire structure.

Therefore, it should not be construed as a limitation to the present utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meanings.
[0039] As Figures 1 - 4 shown, this embodiment provides a lamp with a heat dissipation device. The lamp includes a lighting component 200 and a heat dissipation device. The lighting component 200 can be a daily-use LED lamp, a stage lamp, a fish lamp, an engineering lamp, etc. The heat dissipation device is used to dissipate heat from the lighting component 200 to improve the service life of the lighting component 200.
[0040] Specifically, please continue to refer to Figures 1 - 4 , the lamp includes a housing 100, a heat conduction component 300, and a heat dissipation component 400. The housing 100 includes a first accommodation space 110. The lighting component 200, the heat conduction component 300, and the heat dissipation component 400 are sequentially arranged in the first accommodation space 110 along the Z direction (the first direction) to protect the lighting component 200, the heat conduction component 300, and the heat dissipation component 400 by using the housing 100, and it is convenient for assembly and use. Here, the heat conduction component 300 and the heat dissipation component 400 are partial structures of the heat dissipation device.
[0041] Furthermore, the heat conduction component 300 is disposed to fit the back surface of the lighting component 200. The heat conduction component 300 includes multiple heat pipes 310 that extend along the X direction (the second direction). The heat dissipation component 400 includes a heat absorption fin 410 and heat dissipation fins 420. The heat absorption fin 410 fits the side of the heat conduction component 300 facing away from the lighting component 200. There are multiple heat dissipation fins 420 that extend along the X direction or the Y direction (the third direction). The multiple heat dissipation fins 420 are arranged parallel and spaced apart on the side of the heat absorption fin 410 facing away from the heat conduction component 300 in the direction perpendicular to their extension direction. Along the Z direction, a first heat dissipation hole 121 is provided on the end wall 120 of the housing 100 close to the heat dissipation fins 420. By sequentially arranging the lighting component 200, the heat pipes 310, the heat conduction component 300, and the heat dissipation component 400 in the first accommodation space 110 of the housing 100, the lamp does not require an additional fixing bracket to fix the heat conduction component 300 and the heat dissipation component 400 compared with the prior art lamps, which is beneficial to improving the overall structural stability of the lamp, facilitating assembly and disassembly, and reducing the cost of the lamp. At the same time, the lamp uses the heat pipes 310 to directly fit the back surface of the lighting component 200 to absorb heat, which is beneficial to quickly extracting the heat generated during the operation of the lighting component 200, thereby improving the heat dissipation efficiency. Moreover, the structure of the heat pipes 310 is simple, and it is convenient to set the arrangement density and size of the heat pipes 310 according to the size and heat of the lighting component 200, so that the lamp can be applied to lighting components 200 of different sizes and models, which is beneficial to expanding its application range.
[0042] The setting of the first heat dissipation hole 121 is beneficial to dissipate the heat of the heat dissipation component 400 on one side of the first accommodation space 110, so as to prevent the heat of the heat dissipation component 400 from being enclosed inside the first accommodation space 110, which is beneficial to improving the heat dissipation efficiency. In order to increase the hole area on the end wall 120, the first heat dissipation hole 121 is a honeycomb hole.
[0043] Furthermore, due to the processing technology of the heat pipes 310, when their length is too large and the heat conduction distance is too far, the heat conduction effect at the end is reduced, resulting in a decrease in the heat absorption and conduction effect when applied to large-sized structures. When the lamp is tilted or vertically installed, the phenomenon of hot at the top and cold at the bottom is likely to occur. To solve the above problems, each group of heat pipes 310 has at least two, and the two heat pipes 310 are arranged end to end along the X direction, so as to use two or more heat pipes 310 to conduct heat and dissipate heat respectively, which is beneficial to reducing the temperature difference between the top and the bottom and avoiding the problem of unstable light color caused by a large temperature difference. At the same time, at least two heat pipes 310 are beneficial to ensuring the heat absorption and conduction effect of each heat pipe 310, further improving the flexibility of the setting structure of the heat pipes 310, and making it applicable to large-sized lighting components 200.
[0044] Optionally, the cross-section of the heat pipe 310 is square, so that the surfaces of the heat pipe 310 contacting the lighting component 200 and the heat absorption fin 410 are both flat surfaces, which is beneficial to increasing the contact area between the heat pipe 310 and the lighting component 200 and the heat absorption fin 410, and thus improving the heat conduction efficiency.
[0045] The forming method of the heat dissipation component 400 is extrusion molding, which is beneficial to improving the processing efficiency of the heat dissipation component 400 and reducing the processing cost.
[0046] Now in combination with Figure 4 Describe the detailed structure of the housing 100.
[0047] The housing 100 includes two first side walls 130 and two second side walls 140. Among them, along the X direction, the two first side walls 130 are parallel and spaced apart, and along the Y direction, the two second side walls 140 are parallel and spaced apart. And the two first side walls 130 and the two second side walls 140 are connected end to end at intervals to enclose. The two first side walls 130, the two second side walls 140 and the end wall 120 enclose to form a first accommodation space 110, that is, the housing 100 independently has the first side walls 130 and the second side walls 140 that enclose to form the first accommodation space 110. Here, the second heat dissipation holes 131 are provided on the first side walls 130, and the second heat dissipation holes 131 are correspondingly arranged with the gaps of the heat dissipation fins 420, which is beneficial to the heat to diffuse to both sides from the gaps of the heat dissipation fins 420, thereby improving the heat dissipation efficiency.
[0048] Furthermore, there are multiple second heat dissipation holes 131, and the multiple second heat dissipation holes 131 are spaced apart along the Y direction. While ensuring the heat dissipation efficiency, the connecting ribs between the multiple heat dissipation holes are beneficial to improving the structural strength of the first side wall 130, and thus improving the structural strength of the housing 100.
[0049] Optionally, the second heat dissipation holes 131 are strip-shaped holes, and the dimension of the second heat dissipation holes 131 along the Z direction is greater than the dimension of the second heat dissipation holes 131 along the Y direction, which is beneficial to increasing the heat dissipation area of the second heat dissipation holes 131, and thus improving the heat dissipation efficiency.
[0050] As an optional solution, at least one second accommodation space 150 is further provided on the housing 100, and the second accommodation space 150 is used to arrange structures such as control components and batteries. At the same time, the second accommodation space 150 and the first accommodation space 110 are relatively sealed independent spaces without mutual interference.
[0051] In addition, the lamp with a heat dissipation device further includes a fan 500. The fan 500 is located in the first accommodation space 110, and the fan 500 is arranged on the side of the heat dissipation component 400 away from the heat conduction component 300, that is, the fan 500 is located on the end face of the heat dissipation fin 420 far from the heat absorption fin 410. The fan 500 is used to divert the heat in the gaps of the heat dissipation fin 420, increase the heat flow velocity, and thus improve the heat dissipation efficiency.

Those skilled in the art should understand that the present utility model is not limited by the above-mentioned embodiments. The above-mentioned embodiments and the descriptions in the specification only illustrate the principles of the present utility model. Without departing from the spirit and scope of the present utility model, the present utility model will have various changes and improvements, and these changes and improvements all fall within the scope of the present utility model claimed.
