Combination task lamp and flash light
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.
1. A portable flood lamp, comprising:
a housing having a first end and a second end, said first end having a longitudinal axis;
a plurality of lens/LED assemblies disposed in an array in said first end, each said lens/LED assembly providing a focused beam along a defined illumination axis; and wherein
each lens/LED assembly in the array is oriented such that its defined illumination axis forms the same diverging non-zero angle of substantially 5 degrees+/−3 degrees relative to a reference line centrally disposed within said array and substantially normal to said longitudinal axis, resulting in emission of a uniform flood light beam pattern from an array of focused beam lens/LED assemblies disposed in said first end of said portable flood lamp.
2. The portable flood lamp of claim 1 , wherein the lens/LED assemblies are disposed in a substantially straight line substantially parallel to the longitudinal axis.
3. The portable flood lamp of claim 1 , wherein the lens/LED assemblies are disposed along the perimeter of a polygon substantially centered on said normal reference line and substantially perpendicular to said longitudinal axis.
