Patent ID: 8324790

Claim:
A high illumination LED bulb comprising, in combination: a transparent lamp holder including spaced lower and upper ends, with a bulb socket mounted to the lower end of the transparent lamp holder, with an opening formed in the upper end of the transparent lamp holder; a transparent reflective envelope connected to the upper end of the transparent lamp holder and covering the opening of the transparent lamp holder, with a chamber formed between the transparent lamp holder and the transparent reflective envelope, with an actuator installed in the chamber, with the transparent reflective envelope including an inner surface coated with a reflective membrane having light transmittance characteristic; a radiator received in the chamber and including an upper surface facing the transparent reflective envelope and a lower surface facing the bulb socket; and a light emitting module including a substrate located on the upper surface of the radiator and at least one LED disposed on the substrate, with the light emitting module electrically connected to the actuator so that the LED can be driven to radiate a light beam, and with the light beam radiated from the LED being transmitted to produce a superior projection beam by the transparent reflective envelope and being reflected to produce a inferior projection beam by the reflective membrane of the transparent reflective envelope.
