Disclosed is a light fixture having mirrored surfaces angularly related one to the other and about a light source. The mirrors are either all two-way mirrors or a combination of two-way and one-way mirrors. The arrangement of the mirrors about the light source presents a three-dimensional multiple light source effect, particularly a series of discrete light sources which diminish in intensity and size with depth. Variations of the light fixtures hereof include multisided fixtures, for example fi...

An optical system adapted to direct a plane of light in a 360.degree. pattern. This is accomplished by directing a beam of light from a laser onto and normal with a bundle of fiber optics. The beam is reflected and refracted by the optical elements sufficiently to produce an essentially continuous amplitude plane of light over a 360.degree. pattern.

An improved light trap for use in conjunction with photographic equipment consisting of a frame and an exposure-controlling slide slideably mounted between two longitudinal edges of the frame, the light trap comprising in combination a first flat spring member disposed in a recess in the frame arranged both to bias the slide against a portion of the frame and, upon removal of the slide, to contact an opposite portion of the frame; and a second flat spring member disposed in a recess in the frame...

A signal light, which optionally may be combined with an ashtray base, having a quick-flip switch and a light conducting rod at the top so that when a patron of a restaurant or bar wishes immediate service the switch actuator is flipped and the light comes on to signal the desirability for service. The device comprises a tubular housing in which housing there is a spring for supporting batteries and the housing is mounted on a large circular base which may serve as an ashtray. The switch compris...

A strobe light for use in photography having a low voltage d-c source of energy which is used to provide a charging of high voltage capacitors and with the discharge of the high voltage capacitors through a xenon light producing the output strobe light. The capacitors are charged in steps, such as a first step of one-half of the maximum voltage, and with a second step at the full maximum voltage to increase the efficiency of the charging and the speed of the charging and with a particular switch...

A light unit for attachment to an item of headwear such as a fireman's helmet or a hard hat, and which includes a light source, and a current source for energizing the light source and for actuating electrically driven mechanical means for changing the direction of the light beam from the light source in response to movements of the head of the wearer of the headwear, enabling the beam of light to be directed either in a forward or a downward direction.

A trailer light assembly for use on boat trailers, which assembly is capable of maintaining a light fixture component of the assembly at such a height that the light fixture is not brought into contact with the water when the trailer is being used to launch or retrieve a boat. Maintenance of the desirable height is achieved by having the light fixture move upward or away from the water in response to a flotation device which is attached to the light fixture. The trailer light assembly may also f...

A light fixture comprises a central support body of circular shape presenting on its periphery a plurality of angularly equispaced sockets. Projecting at the interior of each socket cavity there are arranged vertically superposed electrical contacts in the form of male or pin contacts, which are connected to an electric circuit leading to the network. Inside each socket there can be inserted or "nested" a plug made of electrically insulating material, which carries a series of electrical contact...

A method and apparatus for recovering energy from light, such as sunlight, wherein a luminescent fluid is employed in conjunction with photovoltaic means, heat is recovered from the luminescent fluid, and electricity is recovered from the photovoltaic means.

An improved night light structure is arranged to be received directly in an electrical wall outlet and supported by the plug blades received in the outlet socket. The night light itself includes a capacitor in series with a miniature light bulb such that the voltage from the outlet is dropped in value by the capacitor so that the voltage across the bulb is substantially less than its normal voltage rating. As a result, the bulb can last for long periods in excess of ten years. Further, by utiliz...
