Lamp mirror surface covering protection mechanism and lamp

The invention provides a lamp mirror surface covering protection mechanism, and relates to the technical field of lamp structures. Comprising a light-emitting assembly, and a lens is fixedly arranged above the light-emitting assembly through an upper cover; a light guide column is obliquely arranged in the upper cover, one end of the light guide column faces the area above the lens, and the other end of the light guide column is connected to a light sensor so that light reflected by a covered object above the lens can be conducted to the light sensor through the light guide column. The light sensor is electrically connected to a control system, so that when the light intensity detected by the light sensor is higher than a preset value, the light emitting assembly is controlled to be turned off through the control system. The invention further provides a lamp. By means of the LED lamp, potential safety hazards caused by large temperature rise when the lens is shielded can be prevented, and the service life of
