A lamp includes a housing (1), a cooling module (2) and a light emitting diode(3). The housing (1) has an assembling opening (11) and an electrical connection member (12) on two ends of the housing (1), wherein an inner surface of the housing (1) defines a receiving room, and a part of the inner surface of the housing (1) adjacent to the assembling opening (11) is an air-guiding wall (13). The cooling module (2) is disposed at the assembling opening (11) of the housing (1) to form at least one air channel (4) between the cooling module (2) and the air-guiding wall (13), wherein the cooling module (2) has an air-guiding passage (221a) communicating with the receiving room of the housing (1). The light emitting diode (3) is coupled with the cooling module (2). Therefore, there is no air inlet or outlet formed on the housing (1) of the LED lamp, so as to provide a simplified structure and to maintain the exterior integrity of the LED lamp. |
