The reflection cover assembly is provided with multiple reflection piece components, the reflection piece components together form the reflection cover assembly with the profile being round in the radial direction of the reflection cover assembly, the fixing plate assembly is combined with the reflection cover assembly, the switching assembly is combined with the reflection cover assembly, and light emitted by the lamp is uniform by means of flaky structures of the reflection piece components. Besides, on the premise that illuminance is maintained to be the same as that of a lamp in the prior art, a lamp shell or a light uniformizing plate subjected to shot blasting does not need to be used so that glare and dazzling can be avoided, and accordingly a low-power bulb can be adopted when the lamp is assembled to meet the requirement of electricity saving, energy conservation and environment protection spirit.
