An LED lamp includes a lamp base (2), a heat-dissipating unit (6), a reflecting unit (3), aboard (4), and at least one LED (51) mounted on one side (411) of the board (4) facing toward the lamp base (2). The heat-dissipating unit (6) includes a plurality of heat-dissipating fins (62) disposed spacedly along a periphery of the lamp base (2). The reflecting unit (3) has a reflector portion (31) and is connected in a thermal-conducting manner to a side of the heat-dissipating fins (62) opposite to the lamp base (2). The board (4) is connected to the reflecting unit (3) in a manner that the board (4) is spaced apart from the reflector portion (31), and is formed with at least one light-transmissive portion (415). The LED (51) has a light exit side (511) facing toward the reflector portion. Light emitted by the LED (51) is reflected by the reflector portion (31) and exits the LED lamp via the light-transmissive portion (415) of the board (4). |
