Abstract: A fluorescent lamp has a bulb, a phosphor layer and a base. The bulb has a tubular portion and an axially-opposed end portions to each of which a stem mount is welded. Each stem mount has an electrode. Each end portion has a ring-shaped end wall and a portion for welding the stem mount located radially inward from an inner edge of the end wall. The phosphor layer is formed on an inner surface of the tubular portion. The base is provided to cover the stem mount. The base, in outside diameter, is smaller than the bulb and larger than the stem mount such that the end wall of the bulb is exposed.

Abstract: Apparatus and methods for an environmentally resistant germicidal lamp are disclosed. A cover may have a material resistant to at least one of dripping, light splashing, light spraying of liquid and condensation. The cover may have a first section having an opening for receiving a base of a lamp, and an inner surface for encompassing and being slightly larger than an outer cross section of the base when the first section receives the base. The cover may have a second section having an opening for receiving a socket of an electric discharge lamp fixture, and an inner surface for encompassing and being slightly larger than an outer cross section of the socket when the second section receives the socket. The cover may shield and partially enclose electrical contacts of either the base or the socket from at least one of dripping, light splashing, light spraying of liquid and condensation.

Abstract: A lamp receiver includes a first member, and a datum structure having a plurality of first reference surfaces for alignment with respect in a first direction, a plurality of second reference surfaces for alignment in a second direction, and at least one third surface for alignment in a third direction. The first reference surfaces are formed on the first member.

Abstract: A mechanical device that allows for changing a lamp that, when in its operating position, is surrounded by an optical system that is close to the lamp and therefore restricts access for lamp removal and accurate replacement within the optical system. This mechanical device may be used in any lighting product with or without an optical system to facilitate lamp/bulb changes. This mechanical device can be integrated into the structure of various lighting products such as table and floor lamps, ceiling fixtures and pendants, and outdoor poles. A lighting product which has been integrated with this lamp change device has the means to radiate light for desired illumination: a lamp (bulb) surrounded by said light radiator, said bulb is connected to a socket which is further connected to a socket mounting means.

Abstract: A lighting system comprising a reflector and an arc lamp designed for illuminating a wide area with an even light distribution. The reflector has a cap that is generally parabolic in shape except perhaps at its top where it supports an arc lamp. The arc lamp is preferably a high intensity sodium or mercury vapor lamp with a vertical arc tube mounted so that the lowermost part of the arc tube is positioned to be even with the lowermost edge of the cap. The glass bulb housing the arc tube may extend below the lowermost edge. In an alternative embodiment, the lowermost edge of the cap has an extended portion and a short portion. In this embodiment, the lowermost part of the arc tube is even with the short portion.

Abstract: An arc lamp system comprises a power supply coupled to a xenon arc lamp through an interface constructed on a heavy printed circuit board. Such plugs directly into an igniter printed circuit board. In turn, a xenon arc lamp module with heatsinks plugs directly onto banana plugs bolted on the interface printed circuit board. Copper traces buried on inner layers of the interface printed circuit board are very wide and heavy, and kept as short as possible.

Abstract: A mount assembly for supporting the arc tube of a lamp within an outer envelope has first and second axially aligned banding straps. Each of the straps has a closed crimp section and an open crimp section. The straps are positioned so that an open crimp section of one strap overlies a closed crimp section of the other strap, thereby equalizing tensions when the crimps are closed. The mount assembly includes also a mount frame comprised of two elongated rods which are affixed to the banding straps. The straps are mounted upon the glass stem of the lamp.

Abstract: An illumination device is provided and associated with the gas tank of a motorcycle to help illuminate the area in front and to the sides of the motorcycle. The device includes a light panel and a light housing. The light housing is provided with a reflective surface area which reflects light received from a light bulb in the direction in front of the motorcycle and to the side of the motorcycle corresponding to the side of the motorcycle to which the tank is attached.

Abstract: An improved fluorescent lamp is provided with two conductive poles formed at two ends of the lamp. Each conductive pole is contained in a the the lamp tube and includes a a extending contact pin perpendicularly from a conductive pole and extending outwardly from the end portion of the lamp for associating with a contact socket. In start operation, a voltage is supplied to the conductive pole via the contact pin and the contact socket to ionize and start the lamp. The socket is composed of an end cover, a contact plate, and a spring positioned between the end cover and the contact plate, so that the contact pin of the fluorescent lamp may securely engage with the contact socket. The contact plate of the socket further has a concave portion formed at its central portion to securely receive the contact pin of the lamp.

Abstract: This invention relates to a fluorescent lamp unit which comprises a fluorescent lamp, and fluorescent-lamp mounting members mounted at end portions of the fluorescent lamp and for fixing the fluorescent lamp to other members. Between the fluorescent-lamp mounting members and the end portions of the fluorescent lamp, there are provided elastic means mounted so that the fluorescent-lamp mounting members can rotate by an angle not less than 1.degree. relative to the fluorescent lamp, or elastic means mounted so that the fluorescent-lamp mounting means can deflect by not less than 0.1 mm in a longitudinal direction of the fluorescent lamp. The elastic means may be layers of an adhesive. The fluorescent-lamp mounting members may also include screwing means.

Abstract: A tungsten-halogen exposure lamp having a tubular envelope of quartz or high silica glass has a pinch seal at each end with a pair of stiff lead-in wires respectively extending therefrom. Attached to each lead-in wire is an open ended spade lug having a U-shaped portion laying in a plane parallel to the lamp axis. The spade lugs can be coaxially crimped about the lead-in wires. In a light source having an elongated holder with projecting mounting studs spaced from opposite ends of a cylindrical reflector, the tubular lamp is disposed along the vertex of the reflector with the pinch seals projecting through access clearances at opposite ends of the reflector with the spade lugs engaging the mounting studs.

Abstract: A lamp holder that compensates for thermally induced expansion of an arcuate lamp is disclosed. Each end of the arcuate lamp is secured to a relatively flexable lamp support. In the preferred embodiment the lamp support at one end is moveable generally in a plane containing the arcuate lamp, while the lamp support at the other end is moveable generally in a plane that intersects the plane of the lamp. The resulting horizontal and vertical freedom of movement compensates for thermal expansion of the lamp during lamp operation. Both lamp supports are mounted on a lamp holder base, having a plurality of locator pin apertures therein that are cooperatively operative with locator pins positioned on the base of a lamp holder housing. The locator pins and locator pin apertures accurately position the arcuate lamp with respect to an optical system. Forced fluid cooling of the lamp is provided through the lamp holder housing.
