| 摘要 |
The present invention includes an illumination assembly consisting of a light source such as a light emitting diode (LED) that produces a near field image and a means of imaging and focusing the near field image. The means for imaging and focusing the near field image is a convex optical lens having a radius of curvature equal to twice the overall thickness of the lens. The optical lens is installed in fixed spaced relation to the LED such that the lens is imaging the reflector cup of the LED rather than the light on the surface clear LED housing. The lighting assembly is enclosed in a flashlight housing having a means for operating the lighting circuit, a means for retaining a power source and a key ring extension with a slidable latching mechanism.
