A fan comprises a housing, a fan, a heat sink, and a light emitting element. The housing has a compartment and forms an opening. The fan is mounted inside the compartment of the housing and has a frame and an impeller mounted inside the frame. A first air-guiding channel is formed between a peripheral surface of the frame and an inner peripheral surface of the housing. The heat sink is coupled to the fan and has a first surface and a second surface, with the first surface facing the impeller. Also, a second air-guiding channel is formed between an outer periphery of the heat sink and an inner surface of the frame. The light-emitting element is disposed on the second surface of the heat sink. In such arrangement, used components and structural complexity of the lamp can be significantly reduced so as to be convenient in assemblage.
