For example, a side surface of the sealing upper cover facing the heat dissipation cup is provided with a reflection layer, and the reflection layer reflects light rays emitted by the auxiliary LED light emitting body, so that the light rays are better irradiated to the outside.

For another example, in one embodiment, the heat dissipation base of the windmill lamp undertakes a main heat dissipation task, that is, the actual heat dissipation amount undertaken by the heat dissipation base is the largest, in order to pursue better heat dissipation performance, the heat dissipation base is usually designed to be a solid structure, however, the heat dissipation base of the solid structure is too heavy, which is not conducive to transportation and handling, and wastes more materials, and for the above reasons, in order to make the heat dissipation base have the advantages of light weight and good heat dissipation performance, a plurality of through heat dissipation holes or heat dissipation vents are usually provided on the heat dissipation base, 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, so as to achieve the effect of convection heat dissipation, and thus the overall heat dissipation performance of the heat dissipation base can be improved, that is, the outside, 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 the heat dissipation base, 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 base, for example, impurity includes dust, steam and insect etc. if again, impurity accumulations are dust, drop of water and/or insect shell etc..

The heating and opening assembly is used for sealing the internal space in the heat dissipation body structure and avoiding external impurities from entering, and the heating and opening assembly is automatically opened when being heated, namely, when the partial structure of the heating and opening assembly is separated from the heat dissipation body structure, the internal space in the heat dissipation body structure is opened, so that the internal space in the heat dissipation body structure is communicated with the outside, and the convection and heat transfer effect is achieved. The heat dissipation body structure comprises a box body, a first sliding ring, a second sliding ring and a supporting bottom plate, wherein the box body is of a hollow structure, a ventilation cavity is arranged in the box body, an air inlet and an air outlet are arranged on the box body, the air inlet and the air outlet are respectively communicated with the ventilation cavity, the air inlet is aligned with the air outlet, the first sliding ring is arranged around the edge of the box body, the air inlet is communicated with the inner space of the first sliding ring, the second sliding ring is sleeved outside the first sliding ring in a sliding manner, the first sliding ring is provided with a first air inlet hole, the second sliding ring is provided with a second air inlet hole communicated with the outside, the edge of the supporting bottom plate is fixed with the edge of the second sliding ring, and the first sliding ring is used for communicating the first air inlet hole and the second air inlet hole when moving away from the supporting bottom plate and sliding relative to the second sliding ring. Wherein, through set up the ventilation cavity in the box, and first sliding ring reaches the hollow out construction of second sliding ring can make the heat dissipation base has the advantage that the quality is light, works as following air convection route: 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, the first sliding ring, the second sliding ring and the supporting bottom plate to form a closed cavity. It should be noted that, each shape memory alloy ejection spring of the heated ejection assembly is in a heated state, and each shape memory alloy shielding sheet of the heated opening assembly is in a heated state, that is, when heated, heat generated when each LED illuminant of the windmill lamp works and emits light is transferred to the heat dissipation base, so that each shape memory alloy ejection spring of the heated ejection assembly is heated, and each shape memory alloy shielding sheet of the heated opening assembly is heated, of course, when the heated ejection assembly is not heated, and when the heated opening assembly is not heated, each LED illuminant of the windmill lamp stops being powered on and does not emit light.

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. Wherein when the shape memory alloy ejection spring is not heated, the shape memory alloy ejection spring is in a compressed state, but the extension spring is in a stretching state, at the moment, the shape memory alloy ejection spring applies ejection acting force to the box body and the supporting bottom plate, and the tensioning acting force exerted by the extension spring on the box body and the supporting bottom plate is in a balanced state, the first sliding ring and the second sliding ring keep 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 counteract a part of the extension force of the extension spring, the first sliding ring slides towards the direction far away from the supporting bottom plate and relative to the second sliding ring, so that the first air inlet hole and the second air inlet hole are communicated.
