[0012] Furthermore, the seat includes a main body and end plates; the main body is provided with a first through groove and a second through groove, both of which are arranged through each other along a first horizontal direction; the first horizontal direction and the second horizontal direction are perpendicular to each other; the first through groove is located above the second through groove, and the first through groove and the second through groove are separated; two end plates are provided, and are respectively arranged on both sides of the main body along the first horizontal direction, covering the openings of the first through groove and the second through groove, the two end plates and the main body forming the first cavity and the second cavity; the air intake assembly is connected to the end plates.

[0015] Compared with the prior art, the present invention has the following advantages:
[0016] 1. The light-emitting component is disposed on the bottom wall of the first cavity. The light-emitting component can emit light, which can be emitted outward through the light outlet on the top wall of the first cavity and through the diffuser plate. The surface of the diffuser plate is the surface of the light-emitting area of the air-cooled light source of the self-cleaning light-emitting area. The light-emitting component is disposed on the bottom wall of the first cavity so that the heat emitted by the light-emitting component can be conducted to the base. A heat sink is disposed on the inner wall of the second cavity. The heat sink can conduct heat to the air in the second cavity to reduce the temperature of the base and provide heat dissipation for the light-emitting component.
[0017] 2. The air intake component is connected to the second cavity, allowing it to input gas into the second cavity. The gas in the second cavity then flows from the second outlet into the exhaust channel and exits from the first outlet. This allows the high-temperature gas in the second cavity to be expelled, lowering the air temperature and cooling the base, thus dissipating heat from the light-emitting component. Since the two ends of the exhaust channel are connected to the first and second outlets respectively, and the first outlet faces the top of the diffuser plate, the gas exiting the exhaust channel flows towards and past the top of the diffuser plate, blowing away small foreign objects adhering to the top of the diffuser plate and cleaning its surface. This allows the air intake component to continuously clean the surface of the self-cleaning light-emitting area of the air-cooled light source while simultaneously dissipating heat from the light-emitting component, reducing labor costs.

[0028] Furthermore, if the embodiments of this utility model involve descriptions such as "first" or "second", such descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated.
[0029] Please see Figures 1 to 5This utility model provides an air-cooled light source with a self-cleaning surface for the light-emitting area. The air-cooled light source includes a mounting assembly, a light-emitting component 400, and an air intake assembly 500. The mounting assembly includes a base 100, a diffuser plate 200, and a heat sink 300. The base 100 is provided with a first cavity 101, a second cavity 102, an exhaust channel 103, a first air outlet 104, and a second air outlet 105. The first cavity 101 is located above the second cavity 102, and the first cavity 101 and the second cavity 102 are separated. The top wall of the first cavity 101 is provided with a light outlet 106. A diffuser plate 200 is disposed at a light outlet 106; a first air outlet 104 is located at the top of the base 100 and is connected to one end of an exhaust channel 103; the first air outlet 104 is disposed facing the top of the diffuser plate 200; a second air outlet 105 is disposed on the side wall of the second cavity 102 and is connected to the other end of the exhaust channel 103; a heat sink 300 is disposed on the inner wall of the second cavity 102; a light-emitting component 400 is disposed on the bottom wall of the first cavity 101; an air intake component 500 is connected to the second cavity 102; the air intake component 500 can input gas into the second cavity 102.
[0030] 1. The light-emitting component 400 is disposed on the bottom wall of the first cavity 101. The light-emitting component 400 can emit light, which can be emitted outward through the light outlet 106 on the top wall of the first cavity 101 and through the diffuser plate 200. The surface of the diffuser plate 200 is the surface of the light-emitting area of the air-cooled light source of the self-cleaning light-emitting area. The light-emitting component 400 is disposed on the bottom wall of the first cavity 101 so that the heat emitted by the light-emitting component 400 can be conducted to the base 100. A heat sink 300 is disposed on the inner wall of the second cavity 102. The heat sink 300 can conduct heat to the air in the second cavity 102 to reduce the temperature of the base 100 and provide heat dissipation for the light-emitting component 400.
[0031] 2. The air intake assembly 500 is connected to the second cavity 102, allowing the air intake assembly 500 to input gas into the second cavity 102. This allows the gas in the second cavity 102 to flow from the second air outlet 105 into the exhaust channel 103, and then out through the first air outlet 104. This allows the high-temperature gas in the second cavity 102 to be discharged, thereby lowering the air temperature inside the second cavity 102 and cooling the base 100, thus providing a heat dissipation effect for the light-emitting component 400. Since both ends of the exhaust channel 103 are connected to the first air outlet... 104 is connected to the second air outlet 105, and the first air outlet 104 is set towards the top of the diffuser plate 200, so that after the gas in the exhaust channel 103 is discharged from the first air outlet 104, the gas will flow towards the top of the diffuser plate 200 and pass through the top of the diffuser plate 200, so as to blow away the small foreign objects attached to the top of the diffuser plate 200, thereby cleaning the surface of the diffuser plate 200. This allows the air intake component 500 to continuously clean the surface of the light-emitting area of the air-cooled light source while dissipating heat for the light-emitting component 400, and can reduce labor costs.
[0032] Specifically, the air outlet 104 is arranged parallel to the top surface of the diffuser plate 200, so that the air blown out of the first air outlet 104 can pass through the top surface of the diffuser plate 200.
[0033] Specifically, the first horizontal direction is aligned with the length direction of the base 100, the second horizontal direction is aligned with the width direction of the base 100, and the vertical direction is aligned with the height direction of the base 100. The first horizontal direction, the second horizontal direction, and the vertical direction are all perpendicular to each other.
[0034] Reference Figure 2 and Figure 5 In some embodiments of this utility model, multiple heat sinks 300 are provided, and are respectively provided on the top wall, bottom wall and opposite side walls of the second cavity 102; adjacent heat sinks 300 are spaced apart.
[0035] The heat emitted by the light-emitting component 400 will be conducted to the base 110. By setting multiple heat sinks 300, the heat dissipation efficiency of the base 110 can be improved, thereby improving the heat dissipation efficiency of the light-emitting component 400.
[0036] Specifically, heat dissipation plates 300 are provided on the top wall, bottom wall and opposite side walls of the second cavity 102 to further dissipate heat evenly on the seat 110.

[0038] Multiple heat sinks 300 are arranged to extend along the first horizontal direction, and adjacent heat sinks 300 are spaced apart, so that air can flow smoothly between two adjacent heat sinks 300, thereby improving heat dissipation efficiency.
[0039] Specifically, the second cavity 102 is provided with multiple heat dissipation plates 300 on both opposite side walls along the second horizontal direction, and the air flow direction of the air input by the air intake assembly 500 is the first horizontal direction, so as to cooperate with the heat dissipation plates 300 for heat dissipation.
[0040] Reference Figure 2 In some embodiments of this utility model, among the multiple heat dissipation plates 300 disposed on the same wall of the second cavity 102, at least some of the heat dissipation plates 300 have different heights, so as to improve the smoothness of gas flow between adjacent heat dissipation plates 300, thereby further improving the heat dissipation efficiency.
[0041] Specifically, among the multiple heat dissipation plates 300 disposed on the same wall of the second cavity 102, the heat dissipation plates 300 located at both ends of the multiple heat dissipation plates 300 are smaller in height, and the height of the heat dissipation plates 300 arranged one by one towards the middle gradually increases, forming a triangular structure as a whole.
[0042] Reference Figure 2 In some embodiments of this utility model, there are two exhaust channels 103, two first air outlets 104 and two second air outlets 105. The two second air outlets 105 are respectively disposed on the opposite side walls of the second cavity 102. The two ends of the two exhaust channels 103 are respectively connected to the two first air outlets 104 and two second air outlets 105.
[0043] By setting two exhaust channels 103, a first air outlet 104 and a second air outlet 105, the efficiency of gas discharge in the second cavity 102 can be improved, and the cleaning efficiency can be improved by simultaneously cleaning the top of the diffuser plate 200 through the two first air outlets 104.
[0044] Specifically, the two second air outlets 105 are arranged opposite each other so that the gas discharged from the second cavity 102 does not interfere with each other, thereby improving exhaust efficiency; the two first air outlets 104 are arranged opposite each other so that the top of the diffuser plate 200 can be cleaned from both sides through the two first air outlets 104.
[0045] Reference Figures 1 to 4In some embodiments of this utility model, the base 100 includes a seat body 110 and an air guide plate 120; the first cavity 101 and the second cavity 102 are both disposed inside the seat body 110; the light outlet 106 is disposed at the top of the seat body 110; two second air outlets 105 are respectively disposed at the two ends of the seat body 110 along the second horizontal direction; two air guide plates 120 are provided, and are respectively disposed at opposite sides of the seat body 110 along the second horizontal direction; the top of the air guide plate 120 is higher than the top of the seat body 110 in the vertical direction, and an air guide groove 121 is provided on the end face of the air guide plate 120 opposite to the seat body 110. The wall surface of the air guide groove 121 is disposed opposite to the second air outlet 105, and an exhaust channel 103 and a first air outlet 104 are formed between the air guide groove 121 and the outer wall of the seat body 110.
[0046] The air guide plate 120 is provided with an air guide groove 121. The air guide plate 120 is provided with an air guide groove 121 on its end face relative to the base 110. An exhaust channel 103 is defined between the side end face of the base 110 and the groove wall of the air guide groove 121. The top of the air guide plate 120 is higher than the top of the base 110 in the vertical direction, so that the top part of the air guide plate 120 and the top part of the base 110 define a first air outlet 104. The direction of the gas discharged from the first air outlet 104 is horizontal, so as to smoothly blow away small foreign objects on the top of the diffuser plate 200. Of course, depending on the specific situation, the angle between the air discharge direction of the first air outlet 104 and the top of the diffuser plate 200 can be 0° to 45°.
[0047] Two air guide plates 120 are respectively disposed on both sides of the base 110 to form two exhaust channels 103 and a first air outlet 104; wherein, the air guide groove 121 is located in the upper half of the air guide plate 120, and the lower half of the air guide plate 120 abuts against the lower half of the base 110 to improve the gas concentration.
[0048] Specifically, the exhaust channel 103 is located on one side of the first cavity 101 in the second horizontal direction, so as to remove the heat dissipated from the first cavity 101 and further improve the heat dissipation efficiency.
[0049] Specifically, the first horizontal direction is aligned with the length direction of the seat 110, the second horizontal direction is aligned with the width direction of the seat 110, and the vertical direction is aligned with the height direction of the seat 110.
[0050] Reference Figure 3 In some embodiments of this utility model, an air guide slope 122 is provided on the inner wall of the air guide groove 121.
[0051] By setting the air guide slope 122, the airflow through the exhaust channel 103 can be guided, thereby improving the smoothness of the airflow.
[0052] Specifically, the air guide slope 122 is set at the side end of the seat body 110 in a vertical direction.

[0054] The first through groove 113 and the second through groove 114 are both through-connected along the first horizontal direction, so as to form a groove structure at both ends of the main body 111 along the first horizontal direction. The end plate 112 is attached to both ends of the main body 111 along the first horizontal direction, so as to close the first through groove 113 and the second through groove 114, thereby defining the formation of the first cavity 101 and the second cavity 102.
