The light fixture of the present invention includes an open frame, a mounting plate covering one side of the frame, and a lens covering the opposite side of the frame. The mounting plate is a metal stamping which has an integrally formed bracket that is adapted to carry and support a pair of light bulbs, a first light bulb for normal illumination, and a second light bulb for reduced illumination during the night. The light bulbs are disposed in a pair of side-by-side openings in the bracket, and...

A light toy which may be used as a science fiction light ray or as a signalling, marking or illumination device is disclosed. A light source sends a beam of light into a nonopaque tube along its axis. The beam is reflected back into the tube by a reflective surface on the inner side of the cap at the other end. The light emitting device emanates a glow through the walls of the tube making the device highly visible. A kit for converting an ordinary flashlight into a light toy is also disclosed.

Unitary light-handle structure attaches to underwater camera to serve as a properly directed strobe light source structure for the camera and as a handle structure by which the camera can be pointed and controlled. The handle contains the strobe light source, as well as its charging and firing electronics and its power supply batteries.

A fixture for a plurality of tubular electric lamps comprises an elongated insulating angle bar-frame having two flat mutually perpendicular flanges joined by a flat central web at 45.degree. to the flanges. Flat conductors on the inner faces of the flanges carry alternately-disposed pairs of L-shaped brackets which support the lamps in axial alignment. The frame can be secured by self-adhesive bands on the outer faces of the flanges, or by screws passing through the central web.

To permit a portable light meter to operate without zero adjustment and without excessive battery drain, a chopper-stabilized amplifier amplifies the DC signal from the light sensor of the light meter. The chopper in the chopper-stabilized amplifier is an FET circuit having a high impedance compensating circuit to avoid battery drain while compensating for interelectrode capacitance. The power supply obtains the ground level potential from the output of an operational amplifier with negative and...

A camera-mounted illuminating device particularly useful for motion picture photography to provide relatively constant lighting of close-up scenes in motion pictures despite movement of the camera toward and away from the scene.

A light source arranged to be illuminated automatically upon failure of the normal electricity supply to a room, building or the like. The light source comprises a lamp housing containing a bulb, batteries and switch, and a base on which the lamp housing can be mounted. One part of an electromagnet including an energizing winding is mounted in the base and the other part is mounted in the torch housing such that when the housing is mounted on the base and an a.c. supply is made to the base, the ...

A light guard is disclosed adapted to enclose a lamp and the like comprising a reflector section and a cage section which are preferably molded from electrically non-conducting synthetic resins. The light guard is characterized by the manner of detachably securing the two sections together, both for relative pivoting with respect to each other and for latching together. The pivoting structure includes a shaft and slotted sleeve for easy assembly and disassembly and optionally has restraining mea...

A lighting fixture of square, rectangular or triangular shape consisting of a completely enclosed metal box within which the wiring and ballast transformers are contained, with integral portions of the box providing supports for one or more fluorescent lamps and thereby completely eliminating the need to secure to the body of the fixture separate support clips for the lamps. Reductions in material and manufacturing costs as well as shipping costs are realized because of reductions in material us...

Disclosed is a multi-faceted light reflector and a method of manufacturing the reflector. Planar facets are arranged in tiers, or in some other order, tangent to the surface of a spheroid to form the reflector. The size and location of the facets are correlated to the size and location of the illuminated plane. A light source is located at one focus and the illuminated plane is located at the other focus where the illuminated plane is perpendicular to the major axis of the spheroid. The facets a...
