An LED(Light Emitting Diode) lamp is provided to minimize the loss of the light by irradiating the light of the LED installed at a screw-type receptacle to a downwardly inclined direction. An LED lamp(1) includes an optical source unit(10), a heat sink(30), and a housing(50). The optical source unit includes one or more LEDs(11) and a printed circuit board(13). The heat sink is coupled to the PCB. The heat sink discharges the heat of the optical source. The housing supports the heat sink. The housing supports the heat sink. The housing has a thread connection type power supply connector(51). The LED lamp is combined in the thread connection type receptacle. The LED of the optical source unit irradiates the light to the downwardly inclined direction. |
