PROBLEM TO BE SOLVED: To provide a wide-angle illumination device which amplifies an illumination range of a light emitting diode, is achieved in a wider-angle illumination effect, high in luminance, and is improved in a light uniformity effect.SOLUTION: A wide-angle illumination device includes at least a base, a pyramid structural body, a fixing structure, at least one light emitting diode, and an illumination cover. The fixing structure fixes the pyramid structural body on the base, the pyramid structural body has at least three triangle side faces and one uppermost face, and the light emitting diodes are positioned on the uppermost face and the side faces, respectively. There are formed projection faces on which the uppermost face and the respective side faces have different angles toward different directions. |
