An LED(Light Emitting Diode) projector is provided to form a symbol image on a predetermined projection surface such as a screen, a wall, a door, or a floor with simple structure and control scheme. An LED projector comprises plural LED light sources and lens members(12). The lens members entirely encapsulates the LED light sources, and collect the light from the LED light sources on a projection surface(2) in a dot form through the front lens surfaces. The LED light sources are LED chips arranged in rows and columns and individually lighted, or light emitting cells integrated in one chip and individually lighted. |
