The air outlet, the memory alloy shielding sheet body is used to connect the air outlet with the outside world when it is deformed by heat. It should be noted that the memory alloy shielding sheet is used to shield the air outlet when it is not heated, that is, when the memory alloy shielding sheet is heated, its shape is a cuboid, which is the same as the The surface on which the box is attached is a flat surface, so as to have a dust-shielding effect and reduce the entry of external impurities into the heat-dissipating base, that is, both dust-proof and convection heat-dissipating effects. To the effect of conducting the air outlet, that is, the air outlet is communicated with the outside world. At this time, the memory alloy shielding sheet is in a bent state, so that the air outlet is open and directly communicated with the outside world. Based on the shape The memory alloy push spring is also in a heated state, which can make the first air inlet and the second air inlet communicate with each other. Since the second air inlet is also communicated with the outside world, as long as the LED light source When the component emits light and generates heat, the memory alloy shielding sheet can be bent and the shape memory alloy push spring can be elongated, so that the following air convection path can be realized: outside air-the second air inlet hole-so The first air inlet hole - the outer side wall of the box body - the first sliding ring - the second sliding ring and the support bottom plate together form a closed cavity - the air inlet - the ventilation cavity -The air outlet-outside air, that is, the air flows through the second air inlet hole, the first air inlet hole, the outer side wall of the box, the first sliding ring, the second sliding ring in sequence The ring and the support bottom plate together form a closed cavity - the air inlet, the ventilation cavity and the air outlet, so as to complete an air convection path. When the above path is in the working state, the air convection heat dissipation effect can be achieved. , so that the overall heat dissipation performance can be improved, thereby achieving the effect of convective heat transfer. When the first air outlet and the second air outlet are dislocated, and the memory alloy shielding sheet shields the air outlet , the heat dissipation base is isolated from the outside air to prevent external impurities from entering the heat dissipation base.

The heat dissipation base of the above-mentioned detachable light source device is provided with a base body, a heated push-up assembly, and a heated open assembly, in order to reduce the problem of accumulation of impurities in the heat dissipation base, and to have both light weight and heat dissipation performance. good advantage.

It should be particularly pointed out that when the shape memory alloy shielding body is heated and the shape memory alloy push spring is heated, it means that each of the LED light source components of the detachable light source device emits light when working. The generated heat is transferred to the box body, the first sliding ring, the second sliding ring and the supporting bottom plate of the heat dissipation base, so that the shape memory alloy shielding sheet and the shape memory alloy are pushed. The top spring is heated. Of course, when the shape memory alloy shielding body and the shape memory alloy push spring are not heated, it means when each of the LED light source components of the detachable light source device stops energizing and does not emit light. That is, the LED light source assembly does not additionally transmit heat to the box body, the first sliding ring, the second sliding ring and the supporting bottom plate of the heat dissipation base, that is, the shape memory alloy shielding sheet body and the shape memory alloy push spring is in an unheated state. In addition, the material of the shape memory alloy shielding sheet is the shape memory alloy of the existing material, as long as the thermal deformation can be ensured. Of course, those skilled in the art can flexibly use the existing shape memory alloy according to the concept of the present invention material to choose from. Among them, Shape Memory Alloys (SMA) is an alloy material that can completely eliminate its deformation at a lower temperature after heating and restore its original shape before deformation, that is, restore the initial state, that is, it has Alloys with "memory" effect; of course, considering that the shape memory alloy push spring and the shape memory alloy shielding sheet are made of shape memory alloy, the cost is relatively high. Therefore, in the current field of use, the above The design is extremely suitable for some high-end lamps and lanterns that are extremely sensitive to external impurities or have other requirements. Of course, the above design is also suitable for the field of ordinary lamps and lanterns. After the cost of shape memory alloys is reduced, the lamps and lanterns based on the concept of this application will be more widely used. and more favored by consumers.

The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity, all possible combinations of the technical features in the above-described embodiments are not described. However, as long as there is no contradiction between the combinations of these technical features, All should be regarded as the scope described in this specification.

The above-mentioned embodiments only represent several embodiments of the present invention, and the descriptions thereof are specific and detailed, but should not be construed as limiting the scope of the patent of the present invention. It should be pointed out that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can also be made, which all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention should be subject to the appended claims.
