Abstract

A lens arrangement for a telescopic illuminator includes a reflector 1 having a cavity 11 defined therein. An inner periphery of the cavity is annularly formed with a conical surface 111. The conical surface is inwardly inclined. A convex lens 112 is disposed in the cavity and positioned in a middle part of the reflector. A tapered portion 12 is annularly disposed on an outer periphery of the reflector and inclined toward the inner end of the reflector. A flat surface 121 is formed on the inner end of the reflector. The flat surface 121 has a receiving hole 122 centrally defined therein and passing therethrough. A lamp 2 movably is disposed adjacent to the reflector 1. The lamp 2 is borne on aluminium board for dissipating heat. The receiving hole may have a tapered inner periphery. The illuminator may be a flashlight and the lamp may be a LED.
