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..
