Abstract: An illumination unit has a light source, in particular a high-intensity discharge lamp or an ultra high performance lamp, a main reflector and a back reflector with an aperture opposite the main reflector. Light is reflected from the light source through the aperture onto the main reflector. The centers of the light source and the back reflector are located or shaped relative to each other such that a first sector angle (L 2 -L 2 ') enclosed between the light source center and the edge of the back reflector aperture is smaller than 180°. The efficiency of light emission is considerably increased. Preferred embodiments, each of which can cause a further increase in light output, relate to various shapes of the back reflector and the inner walls of the gas discharge space, as well as to the shape of the part of the glass bulb that surrounds the gas discharge space.

Abstract: The invention relates to a high-pressure gas discharge lamp which comprises at least a lamp bulb ( 1 ) hermetically enclosing a discharge space ( 21 ) filled with a gas, a functional layer ( 3 ), and a light emission opening ( 5 ), the latter two being arranged on the outer surface of the lamp bulb, wherein a second layer ( 4 ) covers further regions of the surface of the lamp bulb which do not serve the purpose of the functional layer, while the lamp can be operated at a power such that, given the power level of the lamp, a devitrification of the lamp bulb ( 1 ) and a condensation of the gas are substantially prevented.

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 discharge lamp, at least comprising a burner ( 2 ) which has a burner wall ( 25 ) and a discharge chamber ( 21 ) enclosed by said burner wall ( 25 ), wherein a region with a lowest temperature and a region with a highest temperature establish themselves at the inner and the outer contour of the burner wall ( 25 ), respectively, during operation of the lamp and in dependence on the mounting position of the lamp, and a multilayer interference filter ( 3 ) which is provided on a portion of the outer contour of the burner wall ( 25 ), which interference filter ( 3 ) reflects towards the discharge chamber ( 21 ) mainly light in that wavelength range of the IR light that has a causal relationship to the maximum emissive power of the material of the burner wall ( 25 ).

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.
