摘要:
A flashlight is operable by a power source. The flashlight includes a body having a first end and a second end. The body is configured to support the power source. The flashlight also includes a first light source positioned adjacent the first end. The first light source is electrically coupled to the power source and fixed relative to the body. The flashlight further includes a second light source coupled to the body. The second light source is movable relative to the first light source about a hinge defining a pivot axis.

Die vorliegende Erfindung betrifft eine Taschenlampe mit einem Gehäuse, einer Lichtquelle und einem Lampenkopf mit einer Vorsatzoptik, der zur Fokussierung des abgestrahlten Lichtkegels relativ zur Lichtquelle längsaxial verschiebbar ist. Die Aufgabe der vorliegenden Erfindung ist es, eine Taschenlampe zu schaffen, die einerseits eine leichtgängige Verschiebung des Reflektors relativ zu der Lichtquelle ermöglicht und andererseits ein ungewolltes Verstellen der eingestellten Fokussierung verhindert. Erfindungsgemäß besitzt die Taschenlampe eine Klemmvorrichtung zur Fixierung des Lampenkopfes in einer wählbaren längsaxialen Position.

A portable light apparatus includes a light housing (23) with a light source (75) and a separate battery case (10) connected to the light housing with a cable (22). The light apparatus can be configured and used in several different ways: as a miner light or flashlight, with the light housing secured to an end of the battery case via a snap-in connection (14); as a bicycle light, with the battery case secured to a handlebar stem and the light housing secured to the handlebar or stem; a helmet light, with the battery case attached at the back of the helmet and the light housing at front; and as a headstrap light, with the light housing attached to the headstrap (60) at a front position and the battery casing at a different position, preferably at rear. Clips, brackets and straps are included for adapting the light and battery case to the various purposes, without tools. Preferably the light housing is capable of pivoting on a base, so the user can adjust aim of the light beam.

A portable light intended for mounting on a garment as support includes two LED light sources spaced apart towards the rear of the portable light. A clipped base below on anchor facilitates locating a garment between the anchor and the base , and a spring action urges the base toward the anchor. A hingedly movable head for the LEDs is mounted on the housing to move to and from the housing. An opening of the housing causes a switch in the housing to move between an opened and closed position such that a circuit actives or deactivates the LED lights when the head opens or closes relative to the housing.

A lamp (10) has a base (12) including a longitudinal axis (14) extending in a first direction (16) and a transverse axis (18) extending in a second direction (20) normal to the longitudinal axis (14). A pivot arm (22) is mounted on the base (12) for rotation through 180 degrees about the transverse axis (18) and at least one LED (24) is mounted with the pivot arm (22). Electrical means (26) are enclosed in the base (12) and pivot arm (22) for supplying electrical energy to the at least one LED (24). A cover (13) is mounted with the base (12) and is rotational about the longitudinal axis (14).

A battery life extender for a portable lighting device (10) employs a reconfigurable mechanism (12) operable to selectively electrically isolate one or more batteries (20) from a circuit having a parasitic power drain. For example, a lighting device includes a light generating element (14), at least one battery (20), a user operated switch configured to control delivery of electrical power from the at least one battery to the light generating element, and a housing assembly (18) supporting the at least one battery and the light generating element. The user operated switch can impart a parasitic power drain. The housing assembly is reconfigurable to: (a) a first configuration in which the user operated switch is electrically connected to the at least one battery, and (b) a second configuration in which the at least one battery is electrically isolated and the at least one battery is retained by the housing assembly.

The invention relates to a safety torch. The torch comprises a housing; a light source arranged in a head of the housing, wherein an end of the housing opposite the head forms a handle in which at least one battery system is arranged; and an at least partly translucent light source cover for at least partly covering the light source. The cover is adjustable between a retracted position in which said cover is at least partly retracted in the head of the housing, to emit in use a beam of light, and a protruding position in which the cover is protruding from the housing, at least protruding further from said housing than in said retracted position. The cover is adjustable between said positions by means of an adjusting mechanism comprising two substantially parallel guides arranged in the longitudinal direction of the housing, for adjusting the cover along the guides.
