[0045] Such as Figure 1 and Figure 2As shown, this embodiment provides a lighting device for grouped heat dissipation, the lighting device includes a lighting element 200, and the lighting element 200 can be a daily LED lamp, a stage lamp, a fish lamp, an engineering lamp, etc. In addition, in order to fix the lighting element 200, the lighting device also includes a housing 100, and an opening is provided on one side of the housing 100, and the lighting element 200 is arranged at the opening. The housing 100 includes a bottom wall 110 and a plurality of side walls 120 connected to the bottom wall 110, the bottom wall 110 is parallel to the opening and is located on a side away from the opening, and the plurality of side walls 120 are connected end to end, so as to form a space for accommodating the lighting element 200 inside the housing 100.

[0046] Further, please continue to participate Figure 1 and Figure 2 In order to dissipate heat from the lighting element 200 to ensure the service life of the lighting element 200, the lighting device further includes a heat pipe assembly 300 and a heat dissipation assembly 400 disposed in the housing 100. The heat pipe assembly 300 is attached to the side of the lighting element 200 facing away from the outlet, and the heat dissipation assembly 400 is attached to the side of the heat pipe assembly 300 facing away from the heat pipe assembly 300, so that the heat pipe assembly 300 absorbs heat from the lighting element 200, and the heat dissipation assembly 400 quickly dissipates heat, which is conducive to ensuring the heat dissipation efficiency of the lighting device.

[0047] Due to the following application scenarios, the working state of the lighting element 200 is usually kept at a certain angle to the horizontal plane. At this time, hot air is more likely to rise, resulting in uneven heat dissipation inside the heat dissipation component 400, which is prone to the phenomenon of upper hot and lower cold, resulting in uneven heat near the upper and lower parts of the lighting element 200, thereby affecting the service life of the lighting element 200. In order to solve this problem, Figure 2 As shown, the heat dissipation components 400 can be two groups, the two groups of heat dissipation components 400 are arranged in parallel and at intervals in the housing 100 along the Y direction (first direction). At the same time, the bottom wall 110 is provided with a first ventilation hole 111, and the side walls 120 on both sides along the Y direction are provided with a second ventilation hole 121. The lighting device also includes a partition plate 500, which extends along the Z direction (second direction) and is arranged between the two groups of heat dissipation components 400, so that the airflow entering the two groups of heat dissipation components 400 through the first ventilation hole 111 is discharged from the second ventilation holes 121 on both sides. The partition plate 500 is used to separate the heat dissipation channels of the two groups of heat dissipation components 400, and the air volume exhausted through the second ventilation holes 121 located above and below is the same, avoiding insufficient air volume in the lower part, and placing the air volume flowing upward greater than the air volume flowing downward, avoiding the phenomenon of the upper part being hot and the lower part being cold due to the interference of the upward and downward air volumes, which is conducive to improving the uniformity of heat dissipation, thereby improving the service life of the lighting element 200.

[0048] For example, the partition plate 500 here may be a simple thin plate structure with a simple structure and low cost.

[0049] Now, in combination with Figure 2 the specific structure of the heat dissipation component 400 will be described.

[0050] The heat dissipation component 400 includes a heat dissipation member 410 and a fan 420, and the heat dissipation member 410 and the fan 420 are sequentially arranged in a direction away from the heat pipe assembly 300. Among them, the heat dissipation member 410 has the effect of quickly conducting heat and dissipating heat. Through the first ventilation hole 111 and the second ventilation hole 121, the fan 420 is beneficial to improving the air flow exchange between the inside and the outside environment of the heat dissipation member 410, which is beneficial to further improving the heat dissipation effect.

[0051] More specifically, the heat dissipation member 410 includes a bottom plate 411 and a plurality of first fins 412. Among them, the bottom plate 411 is arranged in contact with the heat pipe assembly 300, and the plurality of first fins 412 are arranged parallel and spaced apart in the X direction (the third direction) on the end face of the bottom plate 411 facing away from the heat pipe assembly 300, so that the interval between two adjacent first fins 412 corresponds to the second ventilation hole 121, so that on the one hand, the interval of the first fins 412 is arranged opposite to the first ventilation hole 111, and on the other hand, it is opposite to the second ventilation hole 121, so that the air flow in the interval can circulate quickly, achieving the effect of quickly dissipating heat, which is beneficial to improving the heat dissipation efficiency of the heat dissipation component 400.

[0052] There are a plurality of fans 420, and the plurality of fans 420 are sequentially arranged in the X direction. The plurality of fans 420 enable them to be arranged according to the size of each heat dissipation member 410, which is beneficial to increasing the area of action of the fans 420, and thus improving the heat dissipation effect.

[0053] Optionally, the first ventilation hole 111 is a honeycomb hole, which is beneficial to increasing the opening area of the first ventilation hole 111, and thus improving the heat dissipation effect. Since the interval between two adjacent first fins 412 extends in the X direction, in order to increase the heat dissipation channels of the second ventilation hole 121 corresponding to this interval, the second ventilation hole 121 is a strip-shaped hole extending in the X direction.

[0054] For the heat pipe assembly 300, it includes a plurality of heat pipes 310, and the plurality of heat pipes 310 are arranged parallel and spaced apart in the Y direction, so as to realize the up-and-down penetration of a single heat pipe 310, which is beneficial to improving the temperature uniformity up and down and avoiding the phenomenon of hot at the top and cold at the bottom. At the same time, the single heat pipe 310 penetrates up and down, reducing the ineffective heat conduction length at both ends of the heat pipe 310, which is beneficial to improving the heat conduction efficiency of the heat pipe 310.

[0055] Optionally, the cross-sectional shape of the heat pipe 310 is square, which is beneficial to increasing the contact area between the heat pipe 310 and the lighting member 200 and the heat dissipation component 400, and thus improving the heat conduction effect.

[0056] In addition, the lighting device further includes an electronic control component 600, which is disposed in the housing 100 and, along the Y direction, is located below the electronic control component 600. Since hot air moves upward, disposing the electronic control component 600 below is beneficial to ensuring the operating temperature. At the same time, the setting of the intermediate partition is beneficial to preventing the upward air volume from flowing downward, which is beneficial to the heat dissipation of the lower electronic control component 600.

[0057] Furthermore, the electronic control component 600 includes a main body 610 and a plurality of second fins 620. The plurality of second fins 620 are arranged in parallel and at intervals along the X direction on the end face of the main body 610 close to the heat pipe component 300, so that the second fins 620 can dissipate heat from the main body 610. At the same time, the second fins 620 communicate between the first fins 412 and the second ventilation holes 121, avoiding the main body 610 from blocking the air duct.

[0058] The lighting device may further be provided with a mounting bracket 700. The mounting bracket 700 is rotatably connected to both sides of the housing 100, so that the lighting direction of the lighting member 200 is adjustable, which is beneficial to improving the flexibility during the use of the lighting device. Preferably, the direction in which the mounting bracket 700 is connected to the housing 100 is perpendicular to the direction in which the second ventilation holes 121 are provided, so as to avoid interference between the installation of the mounting bracket 700 and the second ventilation holes 121.

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