Abstract:
A single combination task lamp and flashlight instrument, 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 an elongated handle that positions the center of mass for optimum balance of the instrument and the control switches for convenient operation according to the sense of touch.
