发明名称 Three color led bulb
摘要 The multi-color light lamp (10) has a base (12) divided into a plurality of segments (14). The three segments are spaced at 120 degrees. More or less segments can be used. An LED (16) is positioned in each segment, the LED in each segment emits a color distinct from the light emitted by the LEDs in the other segments. If the lamp is to be used for automotive purposes, the LED in a first segment emits red light as a taillight and a stop light, the LED in a second segment emits yellow light a turn signal lamp, and the LED in the third segment emits white light as a backup light. A light pipe (18) is operatively associated with the LEDs in each segment for directing emitted light away from the base. The LEDs (preferably two per segment) are mounted upon a thermally efficient printed circuit board (20) such as a flex-on aluminum board.
