A portable illumination device, including a main body, an illumination unit movably disposed on at least a portion of the main body to emit a beam of light and illuminate a surrounding area, at least one sensor disposed on at least a portion of the main body to turn on the illumination unit in response to detecting an external condition, and a surface fastener disposed on at least a portion of the main body to removably connect the main body to an external surface.

A switch includes magnet for biasing a contact arm into a close position, the contact arm forced into an open position when an actuating force is applied to an extending portion of the arm. The switch can be operatively coupled to a zipper system of a container such that a zipper slider, when moved to a closed position of the zipper system, contact the extending portion of the arm to provide the actuating force. A circuit is formed by electrically connecting the switch to a battery and light source. The light source illuminates the interior of the container when the zipper slider is moved from a closed zipper system position.

A hand-held spotlight, having: a housing provided with an accommodating cavity; a power supply box detachably disposed in the accommodating cavity; a switch base connected to the housing and provided with a first clamping block; and a cover body hinged with the housing, wherein the cover body is capable of covering an opening of the accommodating cavity to confine the power supply box within the accommodating cavity, and the cover body is provided with a second clamping block, which is clamped with the first clamping block when the cover body covers the opening of the accommodating cavity, thereby restricting the flipping of the cover body.

A system suitable for use as a restaurant and nightclub receipt reader is provided. The system includes a translucent plate. The system also includes a light emitting diode (LED) configured to provide illuminating light into the translucent plate. The system further includes a battery designed to provide power to the LED. The system includes an on/off switch arranged to turn the LED on and off. The system also includes a clip positionable on a top upper front side of the translucent plate and structured to be utilized to retain a receipt against the front side of the translucent plate allowing a user of the system to effectively view the receipt in low ambient light conditions. Additionally, the system is configured wherein the LED, the battery, the on/off switch, and associated control circuitry for controlling the LED are located under a bottom surface of the clip.

A non-lethal dazzling device includes a laser operable in the visible spectrum. The laser can be a relatively low-powered laser, such as a laser having a maximum output power of 2.5 mW, or it can be a higher-powered laser with a drive circuit that lowers the maximum output power to a safe level based on the range of the hostile target from the laser. In certain embodiments, the disclosed non-lethal dazzling device can be coupled to the bridge of a binocular device.

A utility light mountable to a workpiece including a main body having a first end, a second end opposite the first end, and a length extending between the first end and the second end. A light assembly is coupled to the main body and has a light housing and a light source disposed within the light housing. The light housing is pivotable and rotatable relative to the main body. The utility light further includes a battery support portion configured to selectively receive a battery. The battery support portion disposed at the first end of the main body. A handle assembly is coupled to the second end of the main body. The handle assembly has a first member configured to be grasped for carrying and maneuvering the utility light and a second member that is moveable relative to the first member.

A lighting device for attachment to a handheld electrosurgical instrument is disclosed, which includes an elongated housing having opposed proximal and distal end portions and defining an interior chamber containing a battery powered light assembly for illuminating a surgical site, the housing having at least one smoke evacuation passage that extends from an inlet located adjacent to or near the distal end portion of the housing to an outlet located adjacent to or near the proximal end portion of the housing for removing smoke generated at the surgical site.

An illumination device for a firearm may include a housing supporting multiple lamps. A switch actuator of the device is rotationally coupled to a rear end of the housing. A cam is coupled to the switch actuator, such that the cam rotates with the actuator, the cam having a first end including a magnet and a second end having a shaped cam surface configured to interface with a cam follower. The actuator and the cam are biased toward a neutral position. Selective rotation of the cam causes a magnet of the cam to operate one or more magnetic switches. The cam is transitionable between a plurality of discrete positions, e.g., including a pair of toggle positions in the first rotational direction from the neutral position, and a pair of momentary positions disposed on the cam in the second rotational direction from the neutral position.

A portable lighting device includes a housing, a light source supported by the housing, and an alkaline battery positioned within the housing and coupled to the light source. The alkaline battery is configured to provide a drive current to the light source, and an intensity of the light source is dependent on the drive current. The portable lighting device also includes an electronic processor positioned within the housing and coupled to the light source and the alkaline battery. The electronic processor is configured to monitor a voltage of the alkaline battery, and execute a ramp-up algorithm to control the drive current based on the voltage of the alkaline battery.

In one aspect, a user-wearable illumination assembly includes eyeglass frames and a headlamp removably coupled to the eyeglass frames. Electrical circuitry may be integrated with the eyeglass frames. The headlamp and the eyeglass frames have mounting structure that cooperate to removably support the headlamp thereon. A light source is disposed within the headlamp and electrical communication between the light source and the electrical circuitry of the eyeglass frames is provided by electrical contacts associated with the mounting structures of the headlamp and eyeglass frames. In another aspect, a user-wearable illumination assembly for use with eyeglass frames includes a clip assembly that is selectively removably couplable to a bridge portion of the eyeglass frames, and a headlamp coupled to the clip assembly. The illumination assembly further includes a battery that is selectively removably couplable to the eyeglass frames and at least one electrical conductor coupling the battery to the headlamp.
