For another example, in one embodiment, the heat dissipation body assembly of the closed structure undertakes a main heat dissipation task, that is, the actual heat dissipation amount undertaken by the heat dissipation body assembly is the largest, in order to pursue better heat dissipation performance, the heat dissipation body assembly is usually designed to be a solid structure, however, the heat dissipation body assembly of the solid structure is too heavy, which is not favorable for transportation and handling, and wastes more materials, and for the above reasons, in order to make the heat dissipation body assembly have the advantages of light weight and good heat dissipation performance, a plurality of through heat dissipation holes or heat dissipation vents are usually disposed on the heat dissipation body assembly, and outside air flows from one end of the heat dissipation holes or the heat dissipation vents to the other end of the heat dissipation holes or the heat dissipation vents to achieve an air convection heat dissipation effect, so that the overall heat dissipation performance of the heat dissipation body assembly can be improved, that is, the outside air flow is, with improving whole heat dispersion to set up a plurality of louvres or heat dissipation vent that link up, can also play the light effect of realization quality, however, adopt to set up louvre or heat dissipation vent in order to realize convection heat dissipation's design still to have following problem: because louvre or heat dissipation vent are located inside heat dissipation main part subassembly, the easy entering of external impurity and deposit in louvre or heat dissipation vent lead to the inside problem that appears impurity accumulations easily of heat dissipation main part subassembly, for example, impurity includes dust, steam and insect etc. if again, impurity accumulations are dust, drop of water and/or insect shell etc..

When the second air inlet hole is not communicated with the first air inlet hole, the first sliding ring is used for preventing external impurities from entering the outer side wall of the box body, and the first sliding ring, the second sliding ring and the supporting bottom plate jointly enclose a closed cavity. It should be noted that, each of the shape memory alloy ejection springs of the heated ejection assembly is in a heated state, and each of the shape memory alloy shielding sheet bodies of the heated opening assembly is in a heated state, that is, when heated, heat generated when each of the LED light emitting bodies of the closed structure works and emits light is transferred to the heat dissipation main body assembly, so that each of the shape memory alloy ejection springs of the heated ejection assembly is heated, and each of the shape memory alloy shielding sheet bodies of the heated opening assembly is heated, and of course, when the heated ejection assembly is not heated, and when the heated opening assembly is not heated, each of the LED light emitting bodies of the closed structure stops being energized and does not emit light.

The heated ejection assembly comprises a sliding cylinder body, a limiting part, an extension spring and a shape memory alloy ejection spring, wherein a first end of the sliding cylinder body is fixed with the supporting bottom plate, a second end of the sliding cylinder body penetrates through the box body in a sliding mode and is contained in the ventilation cavity, the limiting part is located in the ventilation cavity, therefore, the sliding cylinder body can be prevented from being separated from the box body based on the blocking effect of the limiting part, the limiting part is fixed with a second end of the sliding cylinder body, the extension spring is sleeved outside the sliding cylinder body, the two ends of the extension spring are respectively fixed with the box body and the supporting bottom plate, and therefore, based on the extension force of the extension elasticity, the first sliding ring and the second sliding ring can be prevented from being separated, and the first air inlet hole and the second air inlet hole can be arranged in a staggered mode, the extension spring is in a stretching state and is used for applying acting force to the box body and the supporting bottom plate to move towards each other so as to enable the box body and the supporting bottom plate to maintain a certain balance state.

For example, the extension spring is made of alloy steel, and the shape of the extension spring is changed little by the temperature rise caused by the heat emitted by the LED luminous body; however, since the shape memory alloy urging spring is made of a memory alloy, a large shape change is caused when the temperature is increased by the heat generated from the LED light emitter. For example, the box body is provided with a sliding installation hole communicated with the ventilation cavity, the second end of the sliding column body penetrates through the sliding installation hole and is accommodated in the ventilation cavity, it should be noted that when the shape memory alloy ejection spring is not heated, the shape memory alloy ejection spring is also in a compressed state, but the extension spring is in an extended state, at this time, the ejection acting force exerted by the shape memory alloy ejection spring on the box body and the support base plate and the tensioning acting force exerted by the extension spring on the box body and the support base plate are in a balanced state, the first sliding ring and the second sliding ring maintain the stability of the motion state, and the first air inlet hole and the second air inlet hole are in a staggered design state, when the shape memory alloy ejection spring is heated, the shape memory alloy ejection spring extends to offset a part of the stretching acting force of the stretching spring, so that the first sliding ring slides towards the direction far away from the supporting bottom plate and relative to the second sliding ring to enable the first air inlet hole and the second air inlet hole to be communicated. For example, when the shape memory alloy ejection spring is heated, the limiting part abuts against the inner side wall of the box body, so that the limiting part is prevented from sliding out of the box body, and the stability of the whole structure is kept.

The heating and opening assembly comprises a fixing strip and a memory alloy shielding sheet body, the fixing strip is arranged on the box body, the memory alloy shielding sheet body is connected with the fixing strip, the memory alloy shielding sheet body is fixed with the outer wall of the box body through the fixing strip, for example, the heating and opening assembly is multiple, each heating and opening assembly corresponds to one air outlet, each memory alloy shielding sheet body is used for shielding one air outlet, the memory alloy shielding sheet body is attached to the box body, the memory alloy shielding sheet body is used for correspondingly shielding the air outlet, and the memory alloy shielding sheet body is used for communicating the air outlet with the outside when being subjected to thermal deformation.
