Abstract:
1. An LED illumination device, comprising: a base including: an LED light source disposed on the bottom end of the body of the base; an optical color wheel, a part of the optical color wheel received within the connecting portion of the base and the optical color wheel directly disposed above the LED light source, and a top surface of the optical color wheel rotatably contacted with a bottom surface of the support portion of the base; thereby heat generated from the optical color wheel is conducted to the fins of the base by physically contacting the top surface of the optical color wheel with the bottom surface of the support portion, light form the LED light source passing through the optical color wheel and being converted to a colored light; a motor arranged outside of the base, wherein the motor has a shaft connected to the optical color wheel and rotated to spin the optical color wheel axially in contact with the support portion of the base; a lens disposed on the support portion of the base; and a holder having a base receiving portion for receiving the base therein and an optical color wheel receiving portion for receiving a part of the optical color wheel therein, wherein the optical color wheel receiving portion is above the base receiving portion and extended outwardly from the base receiving portion; wherein the base, the optical color wheel and the motor are received in the holder; wherein the colored light passed through the lens to form a light beam, and wherein heat generated by the light source and the optical color wheel are conducted to the fins by physically contacting with the base for dissipating thereby.
