Abstract: A fluorescent lamp includes an external electrode and an internal electrode provided at opposite ends of a fluorescent tube. A power conductor may connect to the internal electrode extend outside the tube to provide a connection point for the internal electrode. The tube may include an internal support element at a first end of the tube and a substantially self supporting second end of the tube. A method for assembling a backlight includes obtaining a fluorescent lamp with an external electrode at a first end of a tube, an internal electrode at a second end of the tube opposite the first end, and an internal support element at the second end of the tube. The first end of the tube may be substantially self supporting. The method also connects first and second drive connectors to the first and second ends of the tube.

Abstract: A lamp is disclosed, in particular a halogen incandescent lamp which is intended for the medium-voltage or high-voltage range, having a lamp vessel which is pinched at one end and in whose interior at least one luminous element with at least two luminous element limbs is accommodated, and which is closed by means of a pump rod tip, with the luminous element being fixed in position in the lamp vessel by means of a holding element arranged in the pump rod tip. According to the invention, the holding element is held by means of a centre part in a holding section of the pump rod tip, with free end sections of the holding element being provided for holding the luminous element.

Abstract: A stem and lamp capsule are connected together as an assembly using a retainer such that the stem is clamped to one end of the retainer and the capsule is clamped to the other end of the retainer. An oxidizable fuse is connected between leads of the capsule and electrical conductors of the stem. The retainer maintains the rigidity of the assembly and keeps a constant distance between the stem and the lamp capsule so that the repeatability and failure parameters of the fuse length can be maintained within acceptable tolerance.

Abstract: A mounting structure for an arc tube within an outer envelope of an HID lamp, including an elongated frame supported at one end by a stem assembly and a stem clamp having one or more frame retaining tabs crimped around a portion of the frame.

Abstract: A lamp capsule may be formed with substantially parallelepipedial ends including alignments. A metal strap may surround one end, between the alignments, with first and second oppositely disposed affixation areas of extensions. A glass stem has tubular first portion with outside diameter D. A C-shaped clip is mounted upon the tubular first portion. The clip has height H and inside diameter D1 smaller than the outside diameter D. The clip frictionally engages the tubular first portion. A first frame member has a proximal terminus affixed to the clop and a second frame member has a proximal terminus affixed to the clip opposite the first frame member. The first frame member has a distal terminus affixed to the one affixation area and second frame member has a distal terminus affixed to the other affixation area. The first and second frame members and the metal strap provide the support for the capsule.

Abstract: A backlight unit is disposed beneath a display panel. The backlight unit includes an illumination means, which is used to provide a light source, and a diffuser positioned between the illumination means and the display panel, which is used to scatter the light generated by the illumination means. The diffuser, which is composed of liquid crystal particles and polymer, has a plurality of regions. The region thatis closer to the illumination means has greater scattering effect. In addition, the region with the greatest scattering effect has a shape corresponding to the illumination means.

Abstract: A mount assembly for a lamp has a glass stem (122) having a first portion (124) that is tubular and has an outside diameter D2 and a second portion (118) formed as a pinch seal. A blow-hole (125) is formed in the tubular first portion and is connected to an exhaust tubulation (126). A substantially C-shaped clip (100) is mounted upon the first portion (124). The C-shaped clip (10) has an inside diameter D that is smaller than the outside diameter D2 whereby the clip (100) frictionally engages the first portion (24). A pair of substantially oppositely located cutouts (102, 104) is formed in the clip (10), each providing an extending flap (106, 108) projecting away from the clip (100). This assembly accurately supports the structure and prevents rotation of the mount assembly. An upstanding tab (110) is located substantially midway between the extending flaps, i.e., opposite the open part of the clip, and angled inwardly toward the center of the C-shaped clip (100).

Abstract: A high power strobe lamp has a multi-pin base, an elongated gas-filled tube having a loop formed therein, an anode in one end of the tube and a cathode in the other end of the tube, and the ends of the gas-filled tube being mounted in the base and connected to the pins. A heat dissipating member extends through the loop and a conductive wire, having opposite ends connected to the pins, is spirally wrapped around the tube ends adjacent to the base and extends through the heat dissipating member.

Abstract: In a mounting device for electrically heated, spirally wound wire cathodes in electron guns, two mounting posts joined together by an insulator are configured as sector-shaped sections of a hollow cylinder, and have each a circumferential groove on its end remote from the insulator. The surfaces defining the grooves are parts of common circular and cylindrical surfaces, and the mounting ends of the cathodes are of a configuration approximately complementary to that of the grooves in the mounting posts. The mounting ends therefore lie in a spring-biased and form-fitting manner in the circumferential grooves.

Abstract: A cup-shaped lead-through member is sealed in the wall of a ceramic discharge vessel, and has an electrode beam passing through the end wall of the cup-shaped member and sealed thereto. Immediately adjacent the electrode beam, the cup end wall is deformed away from the discharge space and clamps around the electrode beam over a length of at most the diameter of the beam. A mass of sealing material surrounds the beam end and seals it to the lead-through member, the tight fit of the member end wall to the beam preventing flow of sealing material to the interior of the discharge space.

Abstract: A glass halogen, miniature incandescent lamp comprises at least two conductive pins for electrical contact and a molded seal area for secure mechanical contact in a socket.

Abstract: A high-pressure sodium discharge lamp has a coil electrode wound on a stem which extends axially into a metal tube whose end is sealed into the wall of the lamp envelope. Outside the envelope the tube is rolled or crimped on to the stem and sealed to the stem by brazing.

Abstract: A cup-shaped reflector has a larger open end and a smaller open end. A diffuser glass closes off the larger open end. A lamp is comprised of a lamp bulb having a fused, squashed-flat rear portion hermetically sealing the interior of the bulb, with a plurality of lamp electrodes passing through the squashed-flat rear portion of the lamp bulb and embedded within the material of the squashed-flat rear portion of the lamp bulb. A plurality of lugs is provided, each connected to one of the lamp electrodes at the rear of the lamp, in electrically conductive engagement with the electrodes. A mounting arrangement mounts the lamp bulb on the reflector in the region of the smaller open end of the reflector with at least part of the lamp bulb projecting forwardly into the interior of the reflector.
