Abstract: A moisture resistant lighting tube comprising a flexible, transparent tube of plastic polymeric material housing miniature lamps within the tube interior. Electrical connectors are encased in a hardened thermoplastic potting compound at each end of the tube. The hardened potting compound serves as a dust barrier and strain relief. Moisture free gas such as dried nitrogen is injected in the tube interior under pressure via an opening in the tube wall. The gas displaces moisture laden air within the tube. The air is expelled via another opening in the tube wall. Sealant compound is injected in both wall openings to form sealant plugs which seal the openings from the tube interior, trap the moisture free gas in the tube interior and prevent moisture from entering therein.

Abstract: A matrix lamp bank display utilizes individually removable light filtering assemblies that are composed of a rectangular tinted lens and a supporting frame. Each frame is removably mounted to the display at the front of the lamps provided within it. Each lens is inclined from the vertical to reduce sun or external lighting glare. Provision is made to accommodate thermal expansion of the lens and its supporting frame, as well as ventilation of each lens during lamp operation. Multicolored displays can be achieved by grouping two or more lens colors and operating multiple lamps in combination to project a desired color mix about the matrix.

Further, a flash controlling unit is connected to the lamp-string device to control the flashing of the lamp-string.

Abstract: A series-parallel lighting string having a cord with three wires separated by insulation and a series of cutouts severing the center wire of the cord, and lampholders positioned at each of the cutouts to hold a miniature push-in type light bulb. Each of the lampholders has a pair of contact plates between which a bulb is inserted with its lead wires in contact with the plates. The contact plates are positioned within the housing of the lampholder, and the housing has a snap-fitting cap hingedly attached thereto to define a wireway. Each of the contact plates has an insulation-piercing contact finger positioned to engage one of the end portions of the severed wire to each side of the cutout in the cord. The first and last lampholders in each series set has a second cord-piercing contact finger which contacts one or the other of the outer non-severed wires. The cap or lampholder housing has an insulating divider which projects through the cutout to keep the severed end portions of the central wire separated.

Abstract: A light is provided which includes a first, forwardly concave reflector member, a first, forward lamp spaced ahead of the reflector member, and a second rearwardly concave reflector member spaced forward of the lamp. The rear reflector member has a generally parabolic surface and the forward member has a generally arcuate surface. When the lamp is activated, its rays generally travel forward, are reflected off the second reflector member rearward onto the first reflector member, and thence forward in a substantially parallel array to provide a spot light. A second lamp is located axially rearward of the first lamp and forward of the first reflector. When this lamp is activated, its rays travel generally laterally, strike the first reflector member, and thence are reflected forward in generally random array to provide a flood light. Means are provided to selectively activate either or both of said lamps.

Abstract: Ceiling lights have recessed cans with sockets mounted centrally on a resilient, usually cantilevered, support. A lamp with an integrally connected reflector and external trim ring are connected to the socket. The resilient support pulls the trim ring up against an area of the ceiling surrounding the recessed can, causing the trim ring to act as a self-leveling device for the lamp, while functioning in the manner as a suitable trim for covering the unsightly hole in the ceiling which accommodates the recessed can or fixture. This arrangement allows the near-maximum use of the diametrical width of the opening provided by the recessed fixture as a means of projecting more usable light downward.

Abstract: A solar simulator includes a lamp array of solar lamps pivotally connected to an array frame. The array frame is rotatably and pivotally mounted on a gantry crane, the elevation and lateral position of which are adjustable relative to the position of a solar collector to be tested. The solar simulator maintains the plane of the lamp array parallel to the plane of the test device for all elevations, lateral positions and rotational positions of the lamp array, and controls tilting of the lamps relative to the array frame to any desired angle of incidence. The solar simulator is operated to control the angle of incidence of radiation received by the solar collector to be tested and to vary the distance from the array of lamps to the solar collector in such a manner that the intensity of received radiation along the surface of the test device is uniform, thereby avoiding undesirable lateral gradients in temperature along the surface of the test device.

Abstract: A flexible lighting strip comprises an elongate section of a plastics material having a portion formed as a cylindrical duct which houses a chain of electric lamps. At the rear of that portion is a hollow portion which contains a pair of conductors for feeding the lamps, and which is filled with a translucent polymerizable compound. Between those portions is a portion which has a longitudinal triangular slit, the apex of which opens into the duct so that connections from the conductors to the lamps pass transversely through the slit and are gripped at the apex. A thin metallic sheet covers the filling of translucent compound and is adhered thereto by polymerization of the compound. A double-sided adhesive tape is preferably attached to the metallic sheet for attachment of the lighting strip to a support such as a showcase.
