A lamp includes a housing (1), a heat sink (2, 6), a cooling fan (3, 7) and a light-emitting module (4). The housing (1) has an assembling opening (11) and an electrical connection member (12) on two ends thereof, wherein the housing (1) further comprises an inner wall and a portion of the inner wall adjacent to the assembling opening (11) is an air-guiding wall (13). The heat sink (2, 6) has a base plate (21, 61) disposed at the assembling opening (11) of the housing (1), wherein the base plate (21, 61) has at least one partitioning board (22, 62) defining an air channel (221, 621) of the heat sink (2, 6). A first air-guiding opening (C1) is formed between the air-guiding wall (13) and the at least one partitioning board (22, 62), and a second air-guiding opening (C2) is formed between the air channel (221, 621) and the air-guiding wall (13). The cooling fan (3, 7) is coupled with the heat sink (2, 6) and has an impeller (31, 71). The light-emitting module (4) is coupled with the base plate (21, 61) of the heat sink (2, 6). |
