摘要:
A flashlight having a locking mechanism for securing a head skirt to a head assembly is disclosed. A circuit for temporarily remember the mode of operation of the flashlight is also disclosed.
摘要:
The invention concerns a flashlight with a battery housing (2), with a housing opening (6) for accommodation of flashlight batteries (3), a closure cap (7) for the housing opening (6), with an opening side (9) and an opposing cap side (10) and holders (12a and 12b) located in the closure cap (7) for a spare illuminant (13), which are shaped in such a way that a first end (13a) of the spare illuminant (13) projects on the opening side from the holders (12a and 12b), at least one contact spring (5) projecting on the opening side from the holders (12a and 12b) which can be flexibly deformed in the direction of the cap side (13) for compression retention of the flashlight batteries (3) and a fixed protective element (15) which is located on the first end (13a) of the spare illuminant (13) and which projects on the opening side at least up to the first end (13a) of the spare illuminant (13).
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 flashlight (20) includes a barrel (21) for retaining batteries (31). A reflector (51) and lens (26) located at one end is rotatable axially to vary the reflection dispersion of a light beam emanating through the lens (26) from a lamp bulb (45). An internal cylindrical sleeve (100) within the barrel (21) provides the electrical path between a tail cap (22) adjacent the one electrode end (35) of the batteries (31) and the end (101) adjacent the reflector, lens, and bulb. The sleeve (100) is a non-ferrous nickel plated material for improved conductivity between component parts.

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 (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:
A flashlight comprises a chamber (20) for retaining at least one battery (60,61), and a light source (70). A switch selectively electrically couples said light source (70) and said at least one battery (60,61) retained by said chamber (20). A reflector (440) surrounds said light source (70) to project light from said light sources (70), 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 to selectively electrically couple said light source (70) and said at least one battery (60,61). 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 (70).
