Abstract

In order in a built-in ceiling lamp for high-pressure discharge lamps, in particular metal halide lamps having a clear bulb and compact arc to project onto the working surface a colour spread of the lamp burner without colour location differences even in the event of different colour locations in the burner, freedom from glare being assumed, the built-in ceiling lamp according to the invention is formed with a reflector consisting of a parabolic reflector or spherical reflector, which accommodates the lamp and is provided with a diffusing surface, and of a reflector tube joined to said reflector and provided with a smooth surface. A uniform light distribution is obtained on the working surface without colour location differences and free from glare owing to this combination of two different reflectors. The reflector tube is particularly arranged rotatably in the lamp housing and carries permanently installed slats for deflecting and/or dimming light. A cover plate is inserted between the parabolic reflector and the reflector tube.

Such differences in color location consist of light rings in the area of the usable area that glow red or green The invention is based on the object of a recessed ceiling light the generic type for high pressure discharge lamps, in particular metal halide lamps with clear glass bulb and short arc to create a scattering of the color of the burner of the lamp can project onto the usable surface without differences in color location, with a Glare-free when looking into the luminaire is required. The solution is this The task arises from the characterizing features of claim 1. Through the diffusing, structured surface of the parabolic reflector, which is also a spherical one Can be reflector, the different color spectra of the lamp are mixed so that the burner can spread the color of the burner with no differences in color location on the usable area can be projected through the smooth, especially highly polished surface the reflector tube, which is a truncated cone with a certain cut-off angle, the light radiation is glare-free and without the formation of colored rings on the usable area projected. By combining the parabolic reflector with the reflector tube This results in a uniform light distribution on the usable area without differences in color location and preserved glare-free The parabolic reflector and the reflector tube can be made in one piece be trained. In a particularly preferred manner, the parabolic reflector and The reflector tube, however, has two components that are placed under the cover plate are connected to each other. In this way, the one with the structured, scattering surface provided parabolic reflector by means of the cover plate Protected from dust deposits, whereas the one with smooth, in particular highly polished Surface provided reflector tube the light radiation unaltered by itself In the course of time, sandblast the cover panel, which changes the dust deposits can . The highly polished smooth surface is glare-free, even in the immediate area View into the luminaire at an angle from below. The reflector tube can be rotated in the housing and held on the parabolic reflector firmly inserted in the housing. Thus, the reflector tube be provided with permanently inserted slats for light deflection and light dimming . Resilient retaining elements are provided for easy insertion of the reflector tube into the housing Provided on the reflector tube.
