[0019] It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict, and the present application will be further described in detail below in combination with the drawings and specific embodiments.

[0020] As shown in the accompanying drawings, Figure 1and attached Figure 4 As shown, a heat dissipation system for a lamp includes a heat dissipation assembly mounted on a lamp body 1. The heat dissipation assembly includes a heat dissipation plate 3 whose one end face is fixedly attached to a light-emitting panel 2. The heat dissipation plate 3 and the outer shell of the lamp body 1 are integrally formed from aluminum profiles. A heat sink 4, composed of several parallel heat dissipation fins, is provided on the other end face of the heat dissipation plate 3. Adjacent heat dissipation fins are spaced apart to form a heat dissipation airflow 410. The heat sink 4 is divided into multiple segments along its length to form multiple groups of heat dissipation fins 41. A heat dissipation space 411, communicating with the heat dissipation airflow 410, is formed between adjacent groups of heat dissipation fins 41. Furthermore, a heat dissipation space is formed between adjacent groups of heat dissipation fins 41 and on both sides of the heat sink 4 in the width direction. An air outlet 412 communicates with the heat dissipation space 411. A cooling fan 5 is installed above the heat sink 4. An air guide 6 is installed in the heat dissipation space 411 to guide airflow through the air outlet 412, so that the cooling fan 5 can drive the airflow through the heat dissipation duct 410 and the heat dissipation space 411 in sequence before exiting through the air outlet 412. The heat dissipation fins of the heat sink 4 are divided into multiple segments to avoid the heat dissipation fins being too long and causing uneven heat dissipation, which would affect the working performance of the light panel 2. There is a heat dissipation space 411 with an air outlet 412 between adjacent heat dissipation fin groups 41. Each heat dissipation fin group 41 has a corresponding air outlet 412, thereby solving the problem of airflow in the middle of the heat sink 4 being unable to be discharged due to convergence and mixing. Based on this, the heat dissipation system has the advantages of high-efficiency heat dissipation and uniform heat dissipation.

[0021] As attached Figure 2 and attached Figure 3 As shown, the lamp body 1 is fixedly connected to a fixing plate 7 located above the heat sink 4. The fixing plate 7 has an air inlet 71 corresponding to each heat sink fin group 41. Multiple cooling fans 5 are provided, and the multiple cooling fans 5 are installed one-to-one at the air inlet 71 of the fixing plate 7. Each heat sink fin group 41 has an independent corresponding cooling fan 5, which further improves the heat dissipation efficiency of the heat sink 4.

[0022] As attached Figure 4 As shown, the air guide 6 is provided with an upwardly protruding, parallelogram-shaped protrusion 61. The inclined surfaces on opposite sides of the protrusion 61 are air guide surfaces 610, which guide the airflow through the air outlet 412. Specifically, the protrusion 61 has two air guide surfaces 610. The air guide surface 610 adjacent to the end of the heat dissipation fin assembly 41 and the end face of the heat dissipation fin assembly 41 that is close to it form a right-angled triangle. This facilitates the two air guide surfaces 610 to guide the airflow to the air outlets 412 at both ends of the width direction of the radiator 4, thereby realizing the discharge of the airflow after heat exchange.

[0023] In the embodiment, the height of the protruding part 61 is greater than the height of the heat dissipation fin group 41 to play a blocking role, preventing the airflow from the heat dissipation channels of adjacent heat dissipation fin groups from converging and mixing at the heat dissipation space, thereby affecting the heat dissipation effect.

[0024] As shown in the accompanying drawings Figure 1 and the accompanying drawings Figure 2 As shown in the accompanying drawings, the lamp body 1 is provided with an arc-shaped cover 8 fixedly connected with the heat dissipation plate 3 to form an internal space for mounting the heat dissipation assembly, the arc-shaped cover 8 comprises an arc-shaped part 81 and connecting parts 82 extending downward from both sides of the arc-shaped part 81, the arc-shaped cover 8 can be connected with the heat dissipation plate 3 through the connecting parts 82 on both sides, or the connecting parts 82 on both sides are connected with the heat dissipation plate 3 through the second grid plate 93; specifically, the arc-shaped cover 8 and the heat dissipation plate 3 are combined to form an installation space for accommodating the heat dissipation assembly, thereby playing a protection role.

[0025] In the embodiment, the arc-shaped part 81 is provided with a plurality of first filter screens 90 corresponding to the air inlets 71, and the connecting parts 82 on both sides are provided with a plurality of second filter screens 92 corresponding to the air outlets 412. The first filter screens 90 and the second filter screens 92 effectively prevent some dust and particulate matter from entering the internal space of the arc-shaped cover 8, thereby causing damage.

[0026] In the embodiment, at least two first filter screens 90 are integrally formed to form a first grid plate 91, and the arc-shaped part 81 is provided with a first mounting opening 810 matching the shape of the first grid plate 91; at least two second filter screens 92 are integrally formed to form a second grid plate 93, and the connecting part 82 is provided with a second mounting opening 820 matching the shape of the second grid plate 93, thereby facilitating quick positioning and installation of the first grid plate 91 and the second grid plate 93 on the arc-shaped cover 8.

[0027] Although the embodiments of the present application have been shown and described, it can be understood by those skilled in the art that various equivalent changes, modifications, replacements and variations can be made to the embodiments without departing from the principles and spirit of the present application, and the scope of the present application is defined by the appended claims and their equivalent scope.
