Abstract:
A reflector lamp is described which consist essentially of a light source, in particular in the form of a high-pressure gas discharge lamp (HID [high intensity discharge] lamp or UHP [ultra high performance] lamp), as well as a main or secondary reflector ( 12 ), and a primary reflector ( 25 ) by means of which light from the light source ( 22 ) can be reflected through the light source ( 22 ) onto the main reflector ( 12 ). The primary reflector ( 25 ) is arranged such that those regions of the main reflector ( 12 ) are obscured which are optically inactivated regions, for example because of a lead-through and/or a fastening device for the lamp, which have no reflection properties, or which have reflection properties that adversely affect the radiation characteristic of the reflector lamp. The reflector lamp is particularly suitable for projection applications because of its high luminous efficacy. Furthermore, a substantially automated and accordingly cost-effective assembly of the lamp is possible.

Abstract:
The invention relates to a lamp, e.g. a UHP-Lamp, comprising a burner with an ionizable filling and an amount of mercury contained therein, having at least one closing means ( 40, 50 ) which closes immediately and/or hermetically and/or irreversibly all in- and/or outlets of the lamp to enclose the mercury in the lamp upon detection of an explosion of the burner.
Abstract:
The invention relates to a high-pressure gas discharge lamp which has at least a lamp bulb (2) which hermetically seals off a gas-filled discharge space (21), which lamp bulb (2) has at least a region (3) which does not and/or does not directly serve for the desired light emission of the high-pressure gas discharge lamp, wherein a thermally conducting material is provided which has a higher thermal conductivity than the material Of the lamp bulb (2).
Abstract:
A method of manufacturing partial layers on lamp bulbs, in which method functional layers are provided in thin-film technology, and which method includes at least providing a temporary layer on that region of the lamp bulb which will have no functional layer in the operational state of the lamp, subsequently providing the functional layer on the entire surface of the lamp bulb, and detaching the temporary layer together with the functional layer present thereon.
Abstract:
The present invention prefers to an optical device with a channel waveguide structure as well as a method of fabrication. A thin waveguide layer (2) of a fluoride glass, in particular a Zirkonium fluoride glass, especially ZBLAN, is applied on a substrate (1) and structured to form waveguide channels (7) by pressing a stamp (3) onto said layer (2). The stamp (3) is designed having cutting edges (4) formed according to desired contours of channels (7) of the waveguide structure and providing free space for displacement of material of the waveguide layer (2). The stamp (3) and/or the waveguide layer (2) are preheated to a temperature allowing the displacement of the material of the waveguide layer (2) by the cutting edges (4). The invention allows a fast and cheep production of a channel waveguide structure.

Abstract:
The invention relates to a holder device for manufacturing partial coatings on at least the burner (4) of a lamp bulb (3), comprising at least a retaining element, an adjustment element, and a screen element, wherein the device has a basic body (1) comprising at least one component, which body comprises at least a hollow space (12) in which a portion of the lamp bulb (3) that is not to be coated can be accommodated with clearance, at least a reference region (11) against which a region of the portion of the burner (4) that is not to be coated can be laid in a defined manner substantially without clearance, and at least. a screen (5) that is connected to the basic body (1).
Abstract:
Transparent, temperature-stable coatings based on titanium oxide with a high refractive index and improved thermal and mechanical properties comprise titanium oxide with at least one additive from the group comprising aluminum and/or aluminum oxide, whereby the proportion of A1 atoms in the coating, with reference to the total number of metal atoms in the coating is in the range from 2 to 4%.
