摘要:
A single cell flashlight which comprises a barrel (76), a tailcap (78), a head assembly (77), and a semi-permanently mounted reflector (80), lens (26A) and o-ring (79) within the head assembly; which may be switched on and off by rotation of the head assembly with respect to the barrel; which may be focused upon further rotation of the head assembly with respect to the barrel; which may be used as a source of unfocused, substantially spherical illumination by removal of the head assembly from the barrel; which may be provided with a lanyard or a key ring holder positioned near the head end of the flashlight to provide for simultaneous illumination of a lock as well as its key with one-hand operation of the flashlight; and which is provided with a special tailcap insert (64A) for that a single-cell flashlight employing batteries of a "AAA", "AAAA" or special size batteries.
摘要:
A flashlight reflector assembly (1) including the substantially parabolic reflector (2) having on one surface a reflectorized material, having a hole (10) through its center as its converging end, and a plurality of support ribs (9) extending from the backside of the reflector wherein a stainless steel heat shield (3) is press fit into the back side of the reflector for protecting the reflector from over temperature conditions by reflecting heat back into the lamp and by conducting heat away from the converging portion of the reflector outward to the plurality of pins located behind the reflector reflecting surface.
摘要:
A miniature two or three cell flashlight as disclosed to comprise a barrel, a tailcap, a head assembly, and means for holding a miniature lamp bulb and for providing interruptible electrical coupling to dry cell batteries retained within the barrel and having a recharger for charging the chargeable batteries via conductors in the tailcap.
摘要:
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 light source having a subtantial point source of light, and a movable light source holder. The movable holder may be moved using an actuating member. The relector 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 light source 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 susbtantial point source of light with the reflector axis and the focal point of the reflector. Flashlights employing the combination are provided.
摘要:
A portable lighting device having a plurality of modes of operation and method of operating the portable lighting device are disclosed. One method of operating the portable lighting device is by rotating the portable lighting device along a principal axis of projection of the light source to enter into a new mode of operation. Normal, dim, motion sensitive, variable brightness, blink, right and left hand, lock out, SOS, night light, strobe, compass and signal modes are disclosed, and the modes may be adjusted. A rechargeable battery pack is disclosed that includes a housing, a rechargeable battery, and an accelerometer. A battery cassette is disclosed that provides a negative electrode at each end of the battery cassette, and a central connector that provides a positive electrode at both ends of the battery cassette.

A flashlight comprises a chamber (20) for retaining at least one battery (60), and a light source. A switch (530) selectively electrically couples said light source and said at least one battery (60) retained by said chamber (20). A reflector (440) surrounds said light source to project light from said light sources, and a head component (40) houses said reflector (440) and is rotatably secured to said chamber (20) so that said head component (40) may rotate relative to said chamber (20) without axial movement of said head component (40) relative to said chamber (20) to cause said switch (530) to selectively electrically couple said light source and said at least one battery (60). A bezel (430) is rotatably secured to said head component (40) so that said bezel (430) may rotate relative to said chamber (20) without axial movement of said bezel (430) relative to said head component (40) to cause said reflector (440) to move axially relative to said light source.

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 (82), a light source (3) having a subtantial point source of light, and a movable light source holder (90). The movable holder may be moved using an actuating member. The relector has a first open end (83) for emitting a light beam, a second end (85) and an axis (43) extending between the first and second reflector ends. The light source 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 (58) for moving the substantial point source of light relative to the axis of the reflector and aligning the susbtantial point source of light with the reflector axis and the focal point of the reflector. Flashlights employing the combination are provided.
摘要:
Une lampe-torche (10) comporte un boîtier d'interrupteur séparant le compartiment des piles et le réflecteur. Le col de ce boîtier d'interrupteur est muni d'un support de lampe (58) centré sur le réflecteur. Une rondelle placée à l'arrière du boîtier d'interrupteur obture le compartiment des piles. Le boîtier d'interrupteur peut se déplacer légèrement dans le tube de la lampe-torche (12), ce qui permet un réglage fin de la lampe (60) par rapport au réflecteur et en assure le centrage.
