Patent ID: 8047677

Claim:
A light emitting diode illuminator comprising: a reflecting shell comprising a plurality of hollow tapered bodies, each body having a taper angle being different from that of the other bodies, cooperatively the bodies forming a receiving space therein; a light emitting diode light source installed at an end of the receiving space of the reflecting shell, the light emitting diode light source comprising a column-shaped base and a plurality of light emitting diode arrays, each light emitting diode array comprising a plurality of light emitting diodes being arranged linearly, the light emitting diode arrays being evenly arranged on a curved outer surface of the base; a transparent cover disposed at an opposite end of the reflecting shell away from the light emitting diode light source and configured for directing light emitted from the light emitting diode light source out from the light emitting diode illuminator; and an outer shell mounted around the reflecting shell, two opposing ends of the outer shell being connected to two opposing ends of the reflecting shell, respectively; wherein the reflecting shell is made of translucent reflecting material.
