Patent ID: 7322703

Claim:
A light emitting apparatus which illuminates an illumination area, comprising: a first light source which emits a first light; a second light source which emits a second light; a wheel which is provided with a transmission filter area which transmits the first light, and a reflection area which reflects the second light; a wheel driving unit which controls a rotation of the wheel, and drives the wheel; and a light emitting optical unit which leads the first light which transmits the transmission filter area, or the second light which is reflected by the reflection area to the illumination area, wherein the light which is led to the illumination area by the light emitting optical unit is at least two colors of light which are successively changed over in a time series; wherein the second light source comprises a plurality of light emitting diodes which are arranged on the circumference of a circle, a light emitting diode lighting unit which makes the plurality of light emitting diodes light in order of being arranged on the circumference of the circle during different period in a time series, a rotation optical unit which is rotatably arranged with a rotation center which is a center of the circumference of the circle, in which each light which is emitted from the plurality of light emitting diodes is entered from the light entering end while rotating, and the light thereof is emitted from the light emitting end, and wherein the wheel driving unit and the rotation optical unit are controlled so that the wheel driving unit and the rotation optical unit rotate in synchrony.
