摘要:
A lighting device with improved optical performance and efficiency is provided. The lighting device includes a source of energy, a light source, a reflector and a holder. The reflector has a first open end, a second end, and a parabolic profile extending between the first open end and second end. The focus of the parabolic profile is located outside of the profile. The reflector may also be movable relative to the light source. The lighting device may include a circuit that delivers a pulsed or thermally compensated pulsed current to the light source. The light device may also include a heat sink housing.

A device (5) for a battery with a spacer (6) preventing direct physical contact between first and second batteries (1) arranged in physical series. A resilient conductor (7) providing an electroconductive contact between a center electrode (3) of the first battery and a terminal electrode (4) of the second battery is held by the spacer. A flashlight containing said device for a battery.
摘要:
A flashlight having a main power circuit and a barrel is disclosed. The main power circuit includes a light source and a portable power source for supporting the light source. The barrel is not within the main power circuit. The flashlight also has a ball for holding the light source. The light source is fit and in contact with the inner surface of the ball. The outer circumference of the ball has an array of fin-like protrusions for effectively dissipating heat from the light source.

摘要:
A flashlight (10) has a switch housing in between the battery compartment and reflector. The neck of the switch housing holds a lamp support (58) 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 (12) to allow for a slight adjustment of the lamp (60) relative to the reflector to insure centering.
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.
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:
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.
摘要:
One electrical lead from an LED package is soldered to an inner electrically conductive member positioned and electrically isolated from an outer electrically conductive member by electrically insulating material while a second electrical lead and a neutral lead from the LED are soldered to the outer electrically conductive member so that heat is transferred from an LED die within the LED package to the outer electrically conductive member and then to a thermally conductive outer casing with a thermal path that minimizes thermal resistance.
