摘要:
A bulb including light emitting diodes is optionally used to achieve a variety of light output colors and/or intensities. In some embodiments, the inputs to a three-way bulb are configured to perform other functions, such as power a motor. In some embodiments, a bulb including light emitting diodes includes a replicable cover and/or a replicable LED. This cover may be configured to project images or support a shade made of a heat sensitive material. The bulb may include a digital signal processor and/or a timer.
摘要:
A method for increasing battery life in a lighting device powered by a battery source in which an electronic switch is caused to provide a declining power supply to a light emitting diode (“LED”) as a power profile of the battery source declines.

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.

The invention relates to a push-button arrangement with a housing, a housing opening, a press switch element, a pushbutton facing out of the housing opening, and an elastically deformable hood or cap. The hood or cap has a hood edge which engages from the rear with the opening, and has an inner wall and an insertion ring. The insertion ring has an insertion height and an angular outer ring wall which can be adapted to the inner wall of the cap, and which can be completely received in the hood between the inner hood wall and the pushbutton, and which diameter can be elastically varied section by section along the height of the insertion ring.
摘要:
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.
