Abstract:
A treatment apparatus (10) is used for treatment of parts of a skin (5). The apparatus comprises a radiation source (1) emitting radiation, and a radiator (2) for guiding the emitted radiation to the parts of the skin (5). The parts of the skin (5) comprise skin cells affected by psoriasis. The radiation source (1) emits radiation in a first wavelength range of 400-460 nm, in a second wavelength range of 600-700 nm, or in a first wavelength range of 400-460 nm and a second wavelength range of 600-700 nm.
Abstract:
UV lamp for treatment of the skin, which lamp has a radiation capacity substantially entirely in the UV spectrum and in the red-light spectrum, wherein the radiation capacity of the lamp in the red light spectrum between 600 nm and 700 nm is at least 3% of the radiation capacity in the UV spectrum. In a first embodiment the lamp is a UV fluorescent lamp, having a first UV emitting phosphor and a second red light emitting phosphor, wherein the red light emitting phosphor is CeGdMgB5O10:Tb,Mn. In a second embodiment the lamp is a UV HID lamp, wherein the bulb of the lamp contains LiI and/or CaI2 as a red light radiation salt.
Abstract:
The lighting apparatus according to the invention comprises one or several light sources and a light guide including a light outcoupling structure. The lighting apparatus emits light between 280 and 800 nanometers. It is an object of the invention to provide an improved apparatus for scientific and therapeutic purposes with a light source of planar structure, which can be optimally adapted to an exposed area. This is achieved by light sources or parts of them being easily replaceable. The light sources may be fluorescent lamps based on an Hg, Ne, Xe or Xe/Ne discharge or they may also be LEDs.
Abstract:
A high-pressure gas discharge (HID, high intensity discharge) lamp is described, having a discharge vessel (1) that contains a metal that is applied at least to parts of those regions of the feedthroughs and/or walls of the discharge vessel (1) at which condensation of ingredients of the gas filling may occur as a result of a temperature sink that occurs when the lamp is in a state of operation. In this way, it is possible to at least largely prevent not only chemical interactions between ingredients of the gas filling (particularly the metal halides) and the relevant regions of the feedthroughs or walls at which, due to the lower temperature of these regions, the ingredients condense, but also losses of ingredients of this kind from the gas filling. This in turn means that there is no risk of any damage to the lamp or of any degradation of its lumen maintenance.
Abstract:
A high-pressure metal halide discharge lamp which comprises, as filling, only zinc, a halogen and a noble gas. In order to improve the color rendering index, a calcium halide may be added to the lamp filling. The coupling-in of energy preferably takes place without electrodes in the radio-frequency range or in the microwave range, but may also be carried out by means of metal electrodes.
