摘要： A LED illumination device includes a tapered light guiding member, a LED, a reflective polarizer and a quarter-wave retarder. The light guiding member includes a light input surface and an opposite light output surface. The LED includes a LED chip and a reflective substrate on which the LED chip is mounted. The LED chip faces toward the light input surface. The reflective polarizer faces toward the light output surface, and allows a first polarization light to pass therethrough and reflects a second polarization light back into the light guiding member. The quarter-wave retarder is provided between the LED and the reflective polarizer. The reflective substrate reflects the second polarization light reflected by the reflective polarizer so as to make the second polarization light convert into the first polarization light after the light passes through the quarter-wave retarder a plurality of times.

The sleeve includes a threaded section formed on an internal wall thereof. When the sleeve is sleeved onto the tubular member, the threaded section is located between the first and second threaded portions and stopped against the first threaded portion; meanwhile, the positioning ring can be pushed against the sleeve to fasten the sleeve onto the tubular member. Accordingly, the sleeve can be accurately, rapidly, and conveniently positioned onto the tubular member.
