Abstract:
A flashlight that utilizes an array of one or more light-emitting diodes (LEDs) as a light source, and a light pipe as a light homogenizer to generate a light beam capable of forming a uniformized light distribution at a given distance from the flashlight is disclosed. The LEDs may be all the same color, or some or all may be different colors. A switch, coupled to switching electronics coupled to the LED array, is used to change the state of the LED array to create a variety of different types of light beams, each of which provides relatively uniform and bright illumination at a given distance from the flashlight, wherein the given distance is selectable by adjusting an adjustable imaging lens.
