PURPOSE: An LED illumination lamp is provided to implement optimum brightness by intentionally controlling the angle of a heat sink through rotation of the heat sink. CONSTITUTION: LEDs(120) are arranged in a metal PCB by a specific interval between them. A heat sink(130) emits heat to outside while accommodating the metal PCB. The diffusing plate(140) diffuses a light. A metal case(160) has the heat sink mounted therein. An angle control unit(170) intentionally controls the angle of the heat sink. |
