A lighting system comprises one or more illuminants and a control device for adjusting light parameters of the illuminants during operation. The control device is arranged to adjust the light parameters time-dependently according to a predetermined course of the light parameters. The control device is further adapted to receive a one-dimensional user setting and to change the course of the light parameters according to the one-dimensional user setting.

Lighting system for dynamic lighting control

A lighting system for illuminating an environment is provided. The lighting system comprises at least one controllable light source for generating a light with at least one controllable light parameter, at least one light sensor for detecting a current lighting level in the environment, and a control unit for controlling the at least one light source, wherein the control unit is configured to evaluate sensor data received from the at least one light sensor to determine a current daylight level and to control the at least one controllable light source using a predefined HCL target curve and based on the determined current daylight level. Furthermore, a method for illuminating an environment is provided.

HCL daylight harvesting with dynamic target for light intensity

A lighting system has at least one light fixture and a control device. The at least one light fixture has light parameters. The control device is in communication with the at least one light fixture. The control device has a plurality of one-dimensional user setting, a predetermined sequence of light parameters as a function of time, and an adjustment to the predetermined sequence as a function of a selected one-dimensional user setting.

A luminous means comprising a substrate having a first main surface, to which a first electrode is applied, a second electrode, an organic layer stack within an active region of the substrate between the first and the second electrode, wherein the organic layer stack comprises at least one organic layer which is suitable for generating light, and at least one reflective element, which is formed along a main plane of the luminous means, wherein the luminous means has two operating states, such that the luminous means is an illumination source in a first operating state and the luminous means is a mirror in a second operating state.

Organic lighting device and lighting equipment

A glazing comprising a luminous means with a substrate having a first main surface, to which a first electrode is applied, a second electrode, and an organic layer stack within an active region of the substrate between the first and the second electrode, wherein the organic layer stack comprises at least one organic layer which is suitable for generating light, wherein the luminous means is arranged between two glass plates of the glazing of a window. Also, storage furniture is disclosed comprising a storage element shaped in planar fashion and having at least one storage surface and at least one radiation-emitting component, and at least one holding apparatus for holding the storage element.

An organic luminous means and an illumination device comprising such a luminous means are specified. An optical display apparatus, emergency lighting, motor vehicle interior lighting, an item of furniture, a construction material, a glazing and a display comprising such a luminous means and, respectively, comprising an illumination device having such a luminous means are furthermore specified.

An organic luminous means and an illumination device comprising such a luminous means are described. An optical display apparatus, emergency lighting, motor vehicle interior lighting, an item of furniture, a construction material, a glazing and a display comprising such a luminous means and, respectively, comprising an illumination device having such a luminous means are also described.

A method of producing a ceramic metal halide discharge lamp having a monolithic seal between a sapphire (single crystal alumina) arc tube and a polycrystalline alumina (PCA) end cap. The method includes the steps of providing an arc tube of fully dense sapphire and providing an end cap made of unsintered compressed polycrystalline alumina powder doped with magnesium oxide and yttrium oxide. The end cap is heated until it is presintered to remove organic binder material at a low temperature relative to the sintering temperature. The presintered end cap is placed on an end portion of the arc tube to form a close interface between the two. The presintered end cap and adjacent arc tube are then heated to until the end cap is fully sintered onto the arc tube and the sapphire tube grows into the end cap. A monolithic seal is formed along the interface between the end cap and the arc tube as the sapphire tube grows into the polycrystalline alumina end cap. The yttrium oxide promotes increased growth between sapphire tube and the PCA end cap and is not detrimental to the metal halide chemistry, nor subject to erosion by the metal halide chemistry.

Monolithic seal for a sapphire metal halide lamp

A ceramic metal halide discharge lamp may be made having a monolithic seal between a sapphire arc tube and a polycrystalline alumina cap. The lamp is made by providing an arc tube of fully dense sapphire and providing a cap made of unsintered compressed polycrystalline alumina doped with magnesium oxide and yttrium oxide. The cap is presintered to remove binder material at a low temperature. The presintered cap is placed on an end of the arc tube to form a close interface. The presintered cap and arc tube are then heated to until the cap is fully sintered onto the arc tube and the sapphire tube grows into the cap. A monolithic seal is formed along the interface as the sapphire grows into the polycrystalline alumina.

At least at one end of a discharge lamp, for example a metal-halide discharge lamp or a sodium high-pressure discharge lamp, which has a ceramic discharge vessel (,), a feed-through (,) is provided which includes a cermet. The cermet may be in pin or capillary tube form, and has a metal content which is so high that it can be welded like a metal. The cermet can be directly sintered into an end plug (,) or into an end portion (,) of the vessel itself. The seal thus is effected by a sealing arrangement (,) devoid of glass melt, which would be degraded by attack of corrosive fills within the lamp, while additionally having the capability of withstanding higher operating temperatures.

Lighting system, comprising a mercury-free metal halide lamp with a light yield of at least 75 lm/W and a color rendition index of at least 75 and an electronic ballast, the electronic ballast impressing a square-wave power supply on the lamp and keeping the power constant. The filling comprises the following components:

Mercury-free metal halide lamp

A ceramic discharge vessel for a high-pressure discharge lamp is formed of a cylindrical central part and two hemispherical end pieces, whereby the length of the central part is smaller than or equal to the radius of the end pieces. In this way, the isothermy of the discharge vessel is improved.
