Abstract:
An illumination device for a video presenter includes a light source and an optical lens. The light source radiates light beams incident on a stage where an object to be photographed is placed and arranged inclined at an acute angle with respect to a surface of the stage. The optical lens is arranged between the light source and the stage and inclined to be more parallel to the stage than the light source.
