Abstract: A reflector lamp, in particular a halogen reflector lamp, has a light-transmitting lamp vessel, in which at least one luminous member is accommodated, at least one vessel section of the lamp vessel being provided with a reflective coating. According to the invention, the reflective coating has an interference filter, which is substantially impervious to light in the visible wavelength range and has defined transmission and reflection properties for light in the infrared wavelength range.

Abstract: A method and apparatus for producing a lamp in the case of which a lamp bulb closed at one end is filled through a feed opening for a luminous means are disclosed together with a lamp produced using this method. A dome of the lamp bulb can thereby be of smooth design without a pumping tip.

Abstract: Disclosed is a halogen incandescent lamp having a lamp vessel, which is sealed at one end and in which at least one luminous element is accommodated, a vessel section 42 being in the form of a side reflector which extends only over a subregion of the lamp vessel circumference. A light-exit window 40 adjoins this vessel section 42 in the circumferential direction. According to the invention, the light-exit window 40 is comparatively slightly curved in cross section, the vessel section 42 forming the side reflector bulging out away from the light-exit window 40. This bulged-out region is preferably provided with a kidney-shaped constriction 46.

Abstract: A reflector lamp whose lamp receptacle (1) is provided in part with a reflective coating (6) as well as a reflector contour. The coating is composed of at least two layers of highly heat-resistant metals. One of the layers reflects as well as possible while the superimposed layer absorbs as well as possible.

Abstract: A spiral-wound filament (110) for an incandescent lamp, includes two lead-in wires (1102, 1103), the lead-in wires (1102, 1103) having one bent limb (11021, 11031) each which are arranged in a joint plane that extends off-set in parallel to the winding axis (1104) of the spiral-wound filament (110). An incandescent lamp that has an axially symmetric lamp base (100) and a spiral-wound filament (110) that is off-set in parallel to the lamp base axis (A-A) is also disclosed.

Abstract: The invention relates to a reflector for an electric lamp, and a reflector lamp having an improved fastening of the electric contacts. The reflector body consists of an electrically insulating plastic and, for the purpose of making electric contact with the lamp, has contact lugs that are fixed at least two different locations on the outer side of the reflector body with the aid of claws or barbs integrally formed on the contact lugs.
