Abstract
A single combination task lamp and flashlight, providing separate flood and spot light beams, independently controlled in a three-state sequence by simple push button switches. The two kinds of light beams are produced by separate arrays of compact light emitting devices. both arrays are driven by a single, rechargeable battery powered electrical circuit that provides separate, regulated constant currents to the respective arrays of LEDs. the optics and electronics are constructed in a single, ruggedized, compact module. The module is enclosed within a slim, rugged housing and easily field replaceable with minimal tools.
