Optical signaling device for switch panels, feedback panels or control panels

When setting up control panels, feedback panels and control consoles; Efforts are being made to make the dimensions of the visible equipment and operating elements smaller and smaller in order to be able to accommodate a large number of control and monitoring devices on a narrow tree. The reduction in size does not allow you to go arbitrarily far, because below a certain limit the price for the components shows relatively quickly. tfele Si component-© such * as signal lamps and Bückmelder, ■ take Mnter the board significantly eelfcet bigger than on the blackboard.

The invention relates to a control panel, a feedback panel or a control panel with a variety of optical to signal! Yawing states »According to the invention end at the ^ b ^ ■ St-el-l-ea- the control panel» the feedback panel or the control panel optical fibers or bundles of optical fibers that lead to a separately arranged light control device »that from one or more common light sources and electrically operated screens that interrupt the light path of the individual optical fibers or Liohtleitfaeerbttndel.

The invention is based on an exemplary embodiment according to Drawing explained

Hit 1 is a logging board which, in addition to a loan of anseigeinstrumenten 2 has lines 3, which are interrupted by a plurality of light signal generators 4. In the case of known devices, all light signal cloisters are used. In the subject matter of the invention, these light signal generators are replaced by the light exit surfaces on Lichtlöitfaeörbündeln 5. Each Lichtleitiaserbiinäel consists of a large number of Crlaefaeern from yorsugaweisö 10 - 70 / U are such devices The term "glass fiber optics" has been used. For each signaling one uses a bundle of fibers with a diameter of 3 - 4 mm. Tucked bundles of fibers and gum protection against mechanical damage are surrounded by hoses made of WO, silicone, (kuami or QJeflcn. The length can be a few cm . All Idehtleitfaeerbündel 5 are guided zn a separately arranged from the Sückmeldetafel Lichtsteuergsrät. 6 ip ends, the bundle of optical fibers, one each electrically actuated aperture? · This diaphragm toxuxen on the type of electrical relays from a stromdurchfloosenen coil, a magnetic circuit and a mobile Anchors exist that carries a cover flag. In the light control device 7 öasentladungslampen 8 are arranged below the electrically operated diaphragms, which a uniformly; create diffuse light »The lamps around the blsndea have been placed at such a distance from«

arranged one to the other so that all apertures and thus light 1 or 4 fiber bundles receive an approximately equal luminous flux. When the shutters are closed, the light signal generator 4 remains dark. As soon as a shutter releases the light path through a bundle of fibers, the incoming light is passed on practically without loss by repeated total reflection in the optical fibers χιηά exits at the assigned light signal generator.

The ends of the optical fiber bundle may be in a crystal-clear or transparent colored plastic, for example polyester resin are _t embedded. The Liehtsignalgeber may also consist of a tube, comprising a device aum Ii ¹ Sabklemmen the light eitfaserbündel 1 and at the top with a glass "or plastic lens is completed,

A particularly useful embodiment of the light control device is obtained by arranging all the diaphragms on a cylinder jacket and placing a gas discharge lamp in this cylinder brings in, the axis of which coincides with the cylinder axis. This arrangement results in a optimal © luminous efficiency. In addition, it goes without saying possible to increase the incidence of light in the diaphragms by arranging mirrors or converging lenses »The diameter the fiber optic bundle and / or the light exit surface preferably less than 4 mm.

In the framework of the invention, instead of the optical fiber bundles made of glass fibers also light guides made of a transparent and flexible plastic wire with a diameter of several mm be used"

Bi & light signal generators can be controlled * so that they give continuous light or flickering light.

The main advantage of the invention is that the reliability the signaling is increased extraordinarily. In addition, any compact design is possible and
