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.

A flashlight having a head assembly, a switch assembly and a removable tail cap with a spare bulb holder provided by the tail cap. The spare bulb holder includes a resilient body having an internal, U-shaped wall defining a slot configured to receive a flashlight bulb, a cylindrical wall about the slot and ribs extending between the U-shaped wall and the cylindrical peripheral wall. The slot extends through the cylindrical peripheral wall and includes a first section for receiving the plug of a flashlight bulb, a second section for receiving the flange of a flashlight bulb and a third section for receiving a lens of the flashlight bulb.
摘要:
A flashlight having features that align the light source of a lamp with the principal axis of a reflector, such flashlight having a head assembly that includes a reflector and a lens. The reflector has a central opening that surrounds the principal axis of the reflector. The light source of the flashlight is held by a lamp base and an axis of the lamp base is aligned with the light source. Particularly, the hottest portion of the light source may be aligned with the lamp base axis. The self-centering characteristic of the lamp base is configured with a non-cylindrical feature to be seated in a base receiver. The base receiver includes a receiver axis that is aligned with the principal axis of the reflector. The lamp can include a pair of electrodes and a filament light source extending between the electrodes.

A flashlight has a switch housing in between the battery compartment and reflector. The neck of the switch housing holds a lamp support at a central position within a reflector. An o-ring on the rear of the switch housing seals the battery compartment. The switch housing partially floats within the flashlight tube to allow for a slight adjustment of the lamp relative to the reflector to insure centering.
