Abstract

An LED light source device includes an LED light source dot at least emitting light of one color and a light emission portion emitting light of different colors. The light emission portion includes a light emission portion for a main illumination and for emitting a white light and a light emission portion for a scene illumination and for emitting a colored light. The light emission portion for the main illumination emits the white light and the light emission portion for the scene illumination emits the colored light simultaneously. The LED light source device is a bulb lamp, a candle lamp or other lamps of which a front side and a lateral side both emits light.
