Abstract: A rear window stop lamp for a motor vehicle, which is energizable when the brake of the motor vehicle is applied, has a resin-molded body attached to the interior side of a rear window glass sheet. The resin-molded body has at least one cavity having a curved reflecting surface. An LED chip is disposed in the cavity substantially at a focal point of the curved reflecting surface. A transparent resin-molded body surrounds the LED chip. A light distribution lens plate covers an opening of the cavity for directing rearwardly a light beam emitted from the LED chip and reflected by the curved reflecting surface. The light distribution lens plate comprises a Fresnel lens. A printed electric wire board is embedded in the resin-molded body for energizing LED units. The printed electric wire board is made of a material having a coefficient of thermal expansion which is closer to that of the rear window glass sheet than to that of the resin-molded body.

Abstract: A lamp assembly particularly for a luminaire comprising a lamp having a light emitting member of generally torroidal shape and a reflector positioned and shaped to reflect light received from the light emitting member through the central opening. The light emitting member is preferably a filament of an incandescent lamp. The reflector has a cross-section comprising first and second arcs which are substantially symmetrical with respect to a line joining the center of the reflector and a point substantially at the centre of the torroidal member and the shape of the reflector is that described by rotating said arcs about said line. The arcs may be elliptical or circular for example with their foci or centers positioned to achieve the required effect.

Abstract: A compact and highly efficient warning light for producing high intensity light pulses which are radiated in accordance with a desired directional pattern includes a light source and at least a first reflector disposed within a lens cover. The reflector is coaxial with the lens cover, includes plural parabolic reflective surfaces arranged in a symmetrical pattern and having a common focal point located on the axis of the lens cover, and reflects light in directions which are generally transverse to the lens cover axis. The lens cover is provided with internal optics which redirects light emitted by the source which is not reflected, such redirected light also being radiated in directions generally transverse to the lens cover axis.

Abstract: The invention pertains to a fiber optic lamp system such as those employed in medical diagnostic systems using a cabinet containing a power supply having a front extendible drawer containing a 250 watt focused beam metal halide arc lamp mounted in a removable bracket which includes a sensing tab extension. The bracket sensing tab operates an electrical interlock switch when the proper lamp is properly installed. The interlock switch controls power to the system whose circuit includes pin and floating sleeve electrical connectors which automatically directly completes the circuit to the arc lamp upon the drawer being closed. The amount of light transferred to the fiber optic cable is optimized by offsetting the axis of focused light with respect to the optic cable axis at the cable interface.

Abstract: A headlight lens is fabricated from photochromic glass so that the headlight is not noticeable during daylight hours when subjected to ultraviolet light. At night, in the absence of ultraviolet light, the lens is transparent and emits the light from inside the headlight.

Abstract: An elevator car has a passenger space bounded by a pair of side walls and a ceiling with a fluorescent tube attached to the ceiling and a ceiling frame suspended from the ceiling and supporting translucent filler panels. An opaque middle ceiling strip is attached to the ceiling frame between two of the filler panels and below and in longitudinal alignment with the fluorescent tube. A pair of spot lamps are attached to an upper surface of the middle ceiling strip and are exposed through holes in the strip to illuminate predetermined areas of the side walls containing destination floor actuating elements and information panels for the floors. The middle ceiling strip has one side rotatably attached to the ceiling frame by a hinge connector for providing access to change the fluorescent tube and the spot lamps. The strip also is releasably retained by a locking bar on the other side thereof which engages the ceiling frame and can be released with the aid of a simple tool.

Abstract: A hand held search light includes a miniaturized electronic control circuit for igniting and operating an arc lamp in the light. A lamp mounting arrangement is disclosed for shock mounting the arc lamp, including arrangement to center and focus the light beam emitted by the search light. The search light is modularized for ease of field maintenance by unskilled personnel.

Abstract: A safe light set of the type used for decorative light strings is provided. Each light socket of the set includes a parallel hook having an inner surface with a gripping surface contour formed therein. The hook is formed on the cap of the light socket for engagement with support from which it is hung. The socket includes a short vertical conductor dimensioned to just contact with the threaded metal portion of the bulb when fully engaged within the socket, and to be electrically separated from the metal portion of the bulb when loosening the bulb, at the point at which the metal portion emerges from the socket.

Abstract: A hollow housing which may be flat or in the shape of a sphere has a map extending over at least part of its outer surface representing at least some of the topographical features of the Earth's surface. The map is formed at least partially by openings in the surface, and a light source inside the housing illuminates the openings so that they will stand out in a darkened room. The openings may be holes at the locations of major cities, cuts extending along the continents and rivers separated by bridges, and cut-outs representing major lakes and inland seas.

Abstract: A decorative lighting device for Christmas trees having a rigid branch and a set of flexible branches all made of light conductive material. The flexible branches are attached to the rigid branch at a position intermediate their top and bottom ends. The flexible branches are sized accordingly so that at least a portion of the branch will self supportingly project laterally from the rigid branch. A light source projects light onto the bottom end of the branches. The branches have a diameter such that light travelling through them will substantially diffuse radially along their entire length as well as diffuse axially at the top end. A colored disc positioned between the light source and the branches is adapted to create light color patterns.

Abstract: A flashlight having a main body with a light emitting source at a distal end thereof powered by a battery power source within the main body and a switch at an opposite proximal end encapsulated within a resilient switch jacket defining an oral grasping portion adapted to be held between a user's upper and lower front teeth such that a biting force exerted thereon serves to operate the switch between an open position and a closed position. The proximal end of the main body is sized and configured to prevent accidental, forced entry of the flashlight into the user's oral cavity during use. A neck strap attached at opposite ends to the main body allows the flashlight to be hung about the user's neck in a readily accessible orientation.
