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 emitted by the auxiliary LED light emitting member, so that the light is better irradiated to the outside.

For another example, in one embodiment, the heat dissipation base of the lamp with the push-top structure undertakes a main heat dissipation task, that is, the heat dissipation base undertakes the largest actual heat dissipation amount, 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 with the solid structure is too heavy, is not favorable for 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 disposed 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 an air convection heat dissipation effect, and further improve the overall heat dissipation performance of the heat dissipation base, that is, the outside air flow is used to take away, 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..
