The present invention relates to an illumination device. The illumination device comprises; multiple light sources mounted on a printed circuit board; and a sealing cover which is formed of a transparent or opaque synthetic resin so that a plane corresponding to a substrate has a flat and vertical side. The sealing cover covers the printed circuit board so that the multiple light sources are located in the inner side. The illumination device comprises; a heat radiation plate which is installed to be touched with the lower side of the printed circuit and discharges heats generated from the multiple light sources; a rotary unit in which a warm gear is vertically interlocked with a warm; and a combination unit which sets the rotary unit in the inner side and is fixated on an attachment type bracket. The rotary unit rotates a main body including a lens and the heat radiation plate with a rotary shaft of the warm as the center by rotating the warm. The rotary unit maintains an initial state of an irradiation direction of light outputted to the outside. Therefore, the present invention prevents the main body including the lens and the heat radiation plate from being rotated by wind or impacts when the illumination device is used indoors or outdoors, thereby preventing the generation of light loss and pollution. Also, the present invention prevents the generation of the light loss by preventing the light radiated from the multiple light sources from being reflected to the rear side of the heat radiation plate from the side of the sealing cover. |
