For example, a reflective layer is provided on the side of the sealed upper cover facing the heat dissipation cup, and the reflective layer reflects the light emitted by the auxiliary LED illuminant so that it can better irradiate to the outside.

As another example, in one embodiment, the main heat dissipation box of the lighting box is responsible for the main heat dissipation task, that is, the actual heat dissipation capacity undertaken by the main heat dissipation box is the largest. In order to pursue better heat dissipation performance, usually the The heat dissipation main box is designed as a solid structure. However, the solid structure of the heat dissipation main box 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 box have the advantages of light weight and good heat dissipation performance Usually, a plurality of through cooling holes or cooling vents are opened on the cooling main box, and the outside air flows from one end of the cooling holes or cooling vents to the other end of the cooling holes or cooling vents to achieve air convection heat dissipation. effect, which can improve the overall heat dissipation performance of the heat dissipation main box, that is, use the airflow flowing outside to take away the heat on the heat dissipation main box to improve the overall heat dissipation performance, and open a plurality of through heat dissipation holes or heat dissipation vents, It can also achieve the effect of light weight. However, the following problems still exist in the design of providing heat dissipation holes or heat dissipation vents to realize convection heat dissipation: since the heat dissipation holes or heat dissipation vents are located inside the heat dissipation main box, external impurities are easy to enter and Deposits in the heat dissipation holes or heat dissipation vents lead to the problem of accumulation of impurities in the heat dissipation main box. For example, impurities include dust, water vapor, and insects. For example, the accumulation of impurities is dust, water droplets, and/or insect shells, etc. .

Wherein, 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 box can have the advantage of light weight, when the following air convection path: outside Air-the second air inlet hole-the first air inlet hole-the outer wall of the box, the first sliding ring, the second sliding ring and the supporting bottom plate together form a closed cavity - the air inlet-the ventilation cavity-the air outlet-outside air, when in the working state, can achieve the effect of convection heat dissipation, thereby improving the overall heat dissipation performance, the second air inlet and the first When the first air inlet hole is not connected, the first sliding ring is used to prevent external impurities from entering into the outer wall of the box body, the first sliding ring, the second sliding ring and the supporting bottom plate are jointly surrounded. into 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 the LED illuminants of the lighting box work and emit light, which is transferred to the heat dissipation main box, so that the shape memory alloy ejector springs of the heated ejector components are heated, and the heated ejector components are opened. Each of the shape memory alloy shielding sheets is heated. Of course, when the heated push-up assembly and the heated flip assembly are not heated, it means that each of the LED luminous bodies of the lighting box stops. There is no light when powered on.
