As another example, in one embodiment, the heat dissipation main component of the closed structure undertakes the main heat dissipation task, that is, the actual heat dissipation amount undertaken by the heat dissipation main component is the largest. In order to pursue better heat dissipation performance, the heat dissipation The main component is designed as a solid structure. However, the heat dissipation main component of the solid structure is too bulky, which is not conducive to transportation and handling, and wastes materials. Based on the above reasons, in order to make the heat dissipation main component have the advantages of light weight and good heat dissipation performance, Usually, a plurality of through heat dissipation holes or heat dissipation vents are opened on the heat dissipation main component, and the outside air flows from one end of the heat dissipation holes or heat dissipation vents to the other end of the heat dissipation holes or heat dissipation vents to achieve the effect of air convection heat dissipation , which in turn can improve the overall heat dissipation performance of the heat dissipation main assembly, that is, use the airflow flowing outside to take away the heat on the heat dissipation main assembly to improve the overall heat dissipation performance, and open a plurality of through heat dissipation holes or heat dissipation vents, and also It can achieve the effect of light weight. However, the design of using heat dissipation holes or heat dissipation vents to achieve convective heat dissipation still has the following problems: because the heat dissipation holes or heat dissipation vents are located inside the heat dissipation main component, external impurities are easy to enter and deposit In the heat dissipation holes or heat dissipation vents, the problem of impurity accumulation easily occurs inside the heat dissipation main component.

It should be noted that, through the ventilation cavity provided in the box, and the hollow structure of the first sliding ring and the second sliding ring, the heat dissipation main assembly can have the advantage of light weight, when the following air convection Path: external air - the second air inlet - the first air inlet - the outer wall of the box - the first sliding ring - the second sliding ring and the support base Closed cavity-the air inlet-the ventilation cavity-the air outlet-outside air, that is, the air flows through the second air inlet, the first air inlet, and the outside of the box in sequence The wall, the first sliding ring, the second sliding ring and the supporting base jointly enclose a closed cavity - the air inlet, the ventilation cavity and the air outlet, thereby completing an air convection path, When the above path is in the working state, the air convection heat dissipation effect can be realized, thereby improving the overall heat dissipation performance. When the second air inlet hole is not connected to the first air inlet hole, the first sliding ring is used to prevent external impurities from entering the outer wall of the box body, the first sliding ring, the The second sliding ring and the supporting bottom plate jointly enclose a closed cavity. It should be pointed out that each of the shape memory alloy ejecting springs of the heated ejection assembly is in a heated state, and each of the shape memory alloy shielding sheets of the heated flip assembly is in a heated state, that is, when heated, it is Refers to the heat generated when each of the LED illuminants of the closed structure is working and emitting light, is transferred to the heat dissipation main component, so that each of the shape memory alloy pushing springs of the heated pushing component is heated, and the heat is lifted to open the component. Each of the shape memory alloy shielding sheets is heated. Of course, when the heated push-off component is not heated, and the heated flip component is not heated, it means that each of the LED luminous bodies of the closed structure stops being energized. glow.
