PURPOSE: An LED illumination device is provided to prevent reduction of illuminance by controlling a shape of distribution pattern of light by controlling reflectivity of light. CONSTITUTION: A substrate(10) mounts a plurality of LEDs. A substrate support unit(20) supports and fixes the substrate. A reflective unit(30) forms distribution pattern of light by reflecting light of the LED. The reflective unit does not distribute light to the rear side of the substrate support unit. A plurality of heat sink pins(40) radiate heat of the LED. |
