(5) ОСВЕТИТЕЛЬНОЕ УСТРОЙСТВО(5) LIGHTING DEVICE

II

Изобретение относитс к o6flact 4 светотехники, в частности к осветиI тельным устройствам с регулируемой кривизной отражател и может быть использовано в устройствах дл просмотра и обработки видеоинформационных планок, например аэрофотопленок, рентгеновских пленок и т.д.The invention relates to o6flact 4 lighting engineering, in particular to lighting devices with adjustable reflector curvature and can be used in devices for viewing and processing video information strips, such as aerial films, X-ray films, etc.

Известно осветительное устройство , которое имеет корпус с размещенными в нем газоразр дными лампами и поджигающим электродом-отражателем tn.A lighting device is known which has a housing with gas discharge lamps placed in it and a reflector-igniting ignition electrode tn.

Однако в известной конструкции не предусмотрена регулировка светораспределител осветительного устройства , что не.дает возможности добитьс необходимой равномерности освещенности , рабочей поверхности.However, in the known construction, an adjustment of the light distributor of the lighting device is not provided, which does not make it possible to achieve the necessary uniformity of illumination, the working surface.

Цель изобретени - обеспечение возможности регулировани светораспределени .The purpose of the invention is to provide the ability to control the light distribution.

Указанна цель достигаетс тем, что в осветительном устройстве.This goal is achieved by the fact that the lighting device.

имеющем корпус с размещенными в нем газоразр дными лампами и поджигающим электродом-отражателем, также имеютс стержни, торцовые стенки корпуса имеют поперечные пазы, а стержни закреплены в них с возможностью перемещени , при этом газоразр дные лампы .размещены поочередно со стержн ми , а электрод-отражатель выпол д нен в виде гибкой ленты с пружинными нат жител ми, поочередно охватывающей газоразр дные лампы и стержни и св занной с корпусом посредством пружинных нат жителей.having a case with gas-discharge lamps placed in it and a firing reflector electrode, there are also rods, the end walls of the case have transverse grooves, and the rods are fixed in them with the possibility of movement, while the gas-discharge lamps are placed alternately with the rods, and the electrode is The reflector is made in the form of a flexible tape with spring tension, alternately covering gas discharge lamps and rods and connected to the housing by means of spring tension residents.

IJ На фиг. 1 схематично изображено осветительное устройство, вид сверxyi на фиг. 2 - разрез А-А на фиг. 1.IJ FIG. 1 shows schematically an illumination device, the type of cxyxy in FIG. 2 shows section A-A in FIG. one.

Claims

2Q The illumination device comprises a housing 1, gas discharge lamps 2, an electrode-reflector 3i rods i fixed to move in transverse grooves 5 of the end 39 of the housing 1, spring tensioners 6. The rods are cylindrical in shape and fixed in the housing grooves by nuts 7. The springs 8, screws 9 and nuts 10 provide the necessary force to press the flexible tape of the reflector 3 to the gas discharge lamps.

2. The nuts 7 are weakened and the rods in the slots 5 of the housing 1 can be moved to vary the coverage angle t of the flare of the reflecting electrode 3 of the gas-discharge lamps 2 and, consequently, to change the light distribution of the entire lighting device. Prevent Sagging or overloading of the tape of the electrode-reflector 3 is provided by spring-loaded straps consisting of springs 8, screws 9 and nuts 10. The presence of rods fixed end walls in transverse grooves allows changing the angle of coverage dU the electrode-reflector of gas-discharge lamps, which in turn leads to a change in the shape of the light beam from each lamp and the light distribution of the lighting device as a whole. Claims of the invention A lighting device comprising a housing with gas-discharge lamps placed in it and a firing reflector electrode, characterized in that, in order to provide the possibility of controlling the light distribution, it has rods, the end walls of the housing have transverse grooves, and the rods are fixed in them displacement, while the gas discharge lamps are placed alternately with the rods, and the reflector electrode is made in the form of a flexible tape with spring tension, alternately covering the gas discharge e and rods and the lamp associated with the housing by means of spring tension residents.
