Apparatus and method for aligning a substantial point source of light with a reflector feature
First Claim
1. A flashlight, combination for use in moving a light comprising:
- a portable source of energy;
a reflector including a first open end adapted to emit a light beam, a second end, and a reflector axis which extends through said first open end and said second end;
a light source within the flashlight;
a movable light source holder for holding said light source, said movable light source holder including a base and an actuation interface actuating member, wherein said actuation interface actuating member is used to move said movable light source holder and displace the light source substantially laterally relative to said reflector axis while said light source is electrically coupled to said portable source of energy;
wherein said movable light source holder includes a first electrode contact extending from said light source toward the base of said movable light source holder and a second electrode contact extending from said light source toward the side of said movable light source holder; and
wherein said first and second electrode contacts maintain electrical coupling to said portable source of energy as said light source is moved or displaced substantially laterally relative to said reflector axis.

Abstract
A combination for use in aligning a substantial point source of light with respect to an axis of a reflector is provided. The combination includes a reflector, a lamp bulb having a substantial point source of light, and a movable lamp bulb holder. The movable holder may be moved using an actuating member. The reflector has a first open end for emitting a light beam, a second end and an axis extending between the first and second reflector ends. The lamp bulb is secured to the movable holder and is disposed about the second end of the reflector. The actuating member is operatively coupled to the movable holder at an actuation interface for moving the substantial point source of light relative to the axis of the reflector and aligning the substantial point source of light with the reflector axis and the focal point of the reflector. Flashlights employing the combination are provided.

12. A handheld flashlight, comprising:
-
a portable source of energy; a holder for holding said portable source of energy; a reflector including a first open end adapted to emit light, a second end, and a reflector axis which extends through the first open end and second end; a head assembly coupled to said holder for maintaining said reflector within the handheld flashlight;
a light source positioned relative to said reflector axis and emitting light into said reflector;
said reflector and said light source emitting a light pattern when said light source is in electrical contact with said portable source of energy; anda movable light source holder for holding the light source, wherein the movable light source holder includes an actuation interface for adjusting the light pattern emitted from the handheld flashlight by moving the movable light source holder and aligning the light source substantially laterally relative to the reflector axis while the light source is electrically coupled to the portable source of energy. - View Dependent Claims (13, 14, 15, 16)
