Abstract: The present disclosure relates to a lamp. The lamp comprising a light source module and a shell module. The light source module comprising a circuit board provided with a plurality of light-emitting elements and a fixing ring. The fixing ring comprising an annular substrate, a sidewall connected to an outer edge of the annular substrate, and at least two flanges disposed on an outer surface of the sidewall. The circuit board is disposed on the annular substrate and surrounded by the sidewall. The shell module comprising a base. The base comprising a first surface, a second surface on an opposite side of the first surface, a receiving cavity formed on the first surface, and at least two sliding slots defined on an inner wall of the receiving cavity. The at least two flanges are received in the at least two sliding slots.
