Abstract

An illuminating device is provided. The illuminating device comprises a plurality of illuminating elements, a light mixing-element and a spotlighting-element. The illuminating elements are configured in the light mixing-element or on an end of the light mixing-element to emit the light thereof into the light mixing-element, and scatter the light via the rough interface of the light mixing-element for mixing the lights, which have different color. The light, which is emitted from the light-emitting cross-section of the light mixing-element, will mix by a rough surface and present a specific color. Then the lights are focused by the spotlighting-element to a same direction. This illuminating device can mix the different color lights uniformly and improve the using efficiency of the lights.
