The first sliding ring is provided with a first air inlet hole, and the second sliding ring is provided with a The connected second air inlet hole, the two are switched between dislocation and connected states, the edge of the support base plate is fixed to the edge of the second sliding ring, the support base plate has a cuboid structure, and the support base plate The edge of the first sliding ring is fixed to the inner side wall of the second sliding ring, and the first sliding ring is used to make the first air inlet hole and the The second air inlet hole is connected, so that outside air enters into the inner space of the first sliding ring through the second air inlet hole and the first air inlet hole sequentially. For example, the base body is made of metal, for example, the base body is made of aluminum alloy or copper alloy. 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 installation radiator 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 flip-type heat-dissipating lighting device works and emits light, which is transferred to the heat sink installed, so that each of the shape-memory alloy ejecting springs of the heated ejecting assembly is heated, and the heat is lifted. Each of the shape memory alloy shielding sheets of the opening assembly is heated. Of course, when the heated ejection assembly is not heated, and the heated flip assembly is not heated, it refers to each of the flip-type heat dissipation lighting devices. The LED illuminant stops being powered and does not emit light.

The heated ejecting assembly includes a sliding cylinder, a limiting part, a tension spring and a shape memory alloy ejecting spring, the first end of the sliding cylinder is fixed to the supporting bottom plate, and the first end of the sliding cylinder is The two ends slide through the box and are accommodated inside the ventilation cavity, and the limiting part is located inside the ventilation cavity, so that the sliding can be prevented based on the blocking effect of the limiting part The cylinder is separated from the box, and the limiting part is fixed to the second end of the sliding cylinder, the tension spring is placed outside the sliding cylinder, and the two ends of the tension spring ends are respectively fixed to the box body and the support bottom plate, so that, based on the stretching force of the stretch elasticity, the separation of the first sliding ring and the second sliding ring can be avoided, and the The first air inlet hole and the second air inlet hole are misplaced, the tension spring is in a stretched state and is used to apply a force to the box body and the support bottom plate to move toward each other, and is used to make the The two maintain a certain balance. The shape memory alloy pushing spring is fixed to the box body and the supporting base plate respectively, the shape memory alloy pushing spring is in a compressed state, the tension spring in stretching and the shape in compression The force between the memory alloy pushing springs is balanced, so that the first air inlet hole and the second air inlet hole are misplaced, and the shape memory alloy pushing spring is in a compressed state and is used to The body and the supporting bottom plate exert an active force moving away from each other, and the shape memory alloy pushing spring is used to elongate when heated and deformed, thereby breaking the above-mentioned equilibrium state. The first air inlet hole and the second air inlet The two air inlet holes are changed from a dislocation state to a connected state, so that the outside air passes through the second air inlet hole and the first air inlet hole in sequence, and the first sliding ring is moved away from the support base plate. Direction and sliding relative to the second sliding ring is used to connect the first air inlet hole and the second air inlet hole. For example, the material of the tension spring is alloy steel, and the temperature rise caused by the heat emitted by the LED light emitter has little change in its shape; however, since the material of the shape memory alloy pushing spring is Memory alloy, which can cause a large shape change when the temperature rises caused by the heat emitted by the LED illuminant. For example, the box body is provided with a sliding installation hole communicating with the ventilation cavity, and the second end of the sliding cylinder passes through the sliding installation hole and is accommodated inside the ventilation cavity. Yes, when the shape memory alloy pushing spring is not heated, although the shape memory alloy pushing spring is also in a compressed state, the tension spring is in a stretched state. At this time, the shape memory alloy pushing spring is in a state of tension. The pushing force applied by the box body and the supporting base plate, and the tensioning force applied by the tension spring to the box body and the supporting base plate are in a balanced state, and the first sliding ring and the second sliding ring The two sliding rings maintain the stability of the motion state, and the first air inlet hole and the second air inlet hole are in a state of dislocation design. When the shape memory alloy pushing spring is heated, the shape memory alloy The pushing spring is elongated to counteract the tensile force of a part of the tension spring, so that the first sliding ring slides in a direction away from the supporting bottom plate and relative to the second sliding ring for making the first entry The air hole communicates with the second air inlet hole. For example, when the shape memory alloy pushing spring is heated, the limiting part is against the inner side wall of the box to prevent the limiting part from sliding out of the box, so as to maintain the integrity of the overall structure. stability.

The heated flip-up assembly includes a fixing strip and a memory alloy shielding sheet, the fixing strip is arranged on the box body, the memory alloy shielding sheet is connected to the fixing strip, and the memory alloy shielding sheet passes through The fixing strip is fixed to the outer wall of the box body. For example, there are multiple heated opening components, each of the heated opening components corresponds to one of the air outlets, and each of the memory alloy shielding sheets For covering the air outlet, the memory alloy shielding sheet is attached to the box body, the memory alloy shielding sheet is used to cover the air outlet correspondingly, and the memory alloy shielding sheet is used for heating When deformed, the air outlet is communicated with the outside world. 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, that is, it is in the same shape as the The surface attached to the box body is flat to play a dust-shielding effect and reduce external impurities from entering the installation radiator, that is, it has both dust-proof and convective heat dissipation effects. The memory alloy shielding sheet is used for heating when heated. Play the effect of conducting the air outlet, that is, make the air outlet communicate with the outside world. At this time, the memory alloy shielding sheet is in a bent state, so that the air outlet is opened and directly communicated with the outside world. Based on the The shape memory alloy pushing 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 connected with the outside world, as long as the LED When the illuminant emits light and generates heat, the memory alloy shielding sheet can be bent and the shape memory alloy pushing spring can be stretched, so that the following air convection path can be realized: 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 support bottom plate together form a closed cavity - the air inlet - the ventilation cavity Body-the air outlet-outside air, that is, the air flows through the second air inlet, the first air inlet, the outer wall of the box, the first sliding ring, the second The sliding ring and the supporting base plate together form a closed cavity - the air inlet, the ventilation cavity and the air outlet, thereby completing an air convection path, and when the above path is in a working state, air convection and heat dissipation can be realized effect, 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 misplaced, and the memory alloy shielding sheet covers the air outlet When, the installation radiator is isolated from the outside air, preventing external impurities from entering the installation radiator.
