  • Short-arc high-pressure discharge lamp for digital projection technologies
    Patent number: 6573657
    Abstract: In a short-arc high-pressure discharge lamp (1) with a xenon fill for digital projection purposes, the separation L in mm of the two mutually facing end sections (6a, 8c) of the cathode (6) and the anode (8) when the lamp is hot is given by the relationship 0.8×P≦L≦1×P+1, where P is the lamp power in kW. Further, the diameter D of the circular-cylindrical middle section (8a) of the anode (8) in mm obeys the relationship D≧2.1×L+10.

  • Induction sealed high pressure lamp bulb
    Patent number: 6566814
    Abstract: A high pressure, lamp may be made in a pressure vessel by using an induction coil to melt an edge portion of a sealing wafer pressed against the circumference of an opening in the body of the lamp envelope. The pressure vessel and the lamp envelope are filled with desired fill materials. Induction heating is carried out by the induction coil and induction receiver that presses against the wafer, the lamp envelope or both to hold the melting piece or pieces in contact. The induction receiver may be fused to the lamp body forming a functional part of the overall lamp structure. The preferred resulting lamp includes a bonded metal piece that can be conveniently used for electrical or mechanical coupling or positioning of the lamp with respect to a base.

  • Lamp reflector with a barrier coating of a plasma polymer
    Patent number: 6520650
    Abstract: A no base coat vehicle headlamp reflector can be improved with a plasma deposited layer of a siloxane material. The siloxane layer acts as an barrier layer formed directly on the vehicle reflector. The vehicle headlamp reflector with no base coat, but an barrier layer yields a resin lamp interior protected from upsets in the reflective layer and from outgasing condensate. The lamp reflector coated with plasma polymer of methanol yields a plastic lamp reflector resistant to condensation forming thereon, and resistant to attach by water vapor.

  • Electric incandescent lamp with infrared reflecting layer
    Patent number: 6424089
    Abstract: Electrical incandescent lamp, in particular a halogen incandescent lamp (4) having a lamp bulb (5) which has a coating (9) that reflects IR radiation, and having a flat luminous body (10) which defines a fictional plane of the light and is arranged inside the lamp bulb (5). The shape of the lamp bulb (5) with respect to those axes which lie in the plane of the light have no rotational symmetry, but the lamp bulb (5) in fact has a shape which differs from rotational symmetry but is matched to the flat geometry of the luminous body (10), that is to say a flattened shape, in particular the shape of an ellipsoid, whose shortest half-axis is oriented at right-angles to the fictional plane of the light of the luminous body (10).

  • Blue tinted automobile lamp capsule
    Patent number: 6369510
    Abstract: The invention involves application of a luster coating to the exterior of a glass lamp capsule envelope to obtain a blue coloration of the transmitted light. The result is a higher color temperature light source that is commercially preferred. The preferred blue luster is formed from a coating solution containing organometallic components and solvent, that is heat treated in an oxidizing atmosphere to form a gold containing bismuth-titanium oxide material. The filament is adjusted to yield the overall necessary number of lumens. The blue luster tinted automobile lamp capsule is a durable, and yields the proper number of lumens with little or no increase in glare. The blue luster tinted lamp capsule is therefore compliant with legal standards.

  • Lamp with a slip on envelope retainer and clamp ring
    Patent number: 6356009
    Abstract: A lamp, whether HID or other, can be conveniently held by with slip ring that compresses flexible arms against the lamp end. The arms are formed to conform on and inner side with and exterior portion of the lamp. On their exterior side of the arms are formed to mate in compression with a slip ring. By tapering the arms with respect the slip ring, and increasing pressure can be induced that flexes the arms to hold the lamp in place. The slip ring can be further formed to bind the slip ring with three clamp arms, and thereby resist disengagement of the structure once assembly is completed. The result is a securely held lamp accurately held by inexpensive parts adaptable to rapid machine assembly.
