Definitions
- the invention relates to an optical device Display of characters as well as the use of a electroluminescent filament for visual display of characters.
- the visual display of characters is known to find wide areas of application.
- characters such as groups of letters or coat of arms.
- Illuminated letters have so far been customary, specially shaped use luminous objects such as discharge tubes.
- the character to be displayed is the one to be displayed Character group by the external shape of the luminous Property.
- arrays become brighter Objects, such as light emitting diodes, are used that are arranged in this way are that by their optional activation different Characters can be represented.
- the devices for the optical representation of characters in Form of fluorescent tubes have the disadvantage that they each used only to represent a single group of characters can be, for example, with light-emitting diode arrays the disadvantages are that they are comparative are faint and to represent various Characters are operated by means of a control device have to.
- the invention is based on the object a device for the optical representation of characters create enough light intensity to achieve has optical effects and for variable optical display of characters is suitable.
- the object is also achieved by a device for optical display of characters with at least one electroluminescent Filament of a predetermined diameter and a base plate, on the surface of which the filament according to the course of the character to be displayed, for example according to the course of the lettering, the Numbers or the contours of other shapes to be displayed, is attached for example by gluing and / or by Staple or staples.
- the invention also relates to the use of a electroluminescent filament for visual display of characters.
- the device for optical display shown in Fig. 1 of characters has a base plate 1, which is made of light machinable material.
- the surface 2 of the base plate 1 has depressions in the form of grooves 3, 4.
- the groove 3 forms the letter "V"
- the shape of the groove 4 is that of the letter "B” corresponds.
- the grooves 3 and 4 serve to receive a filament 5, which has electroluminescent material.
- the grooves 3, 4 have such a width that the filament 5 is held in them.
- a cover plate 6 provided, which consists of transparent material.
- the depth and the width of the grooves 3, 4 essentially correspond the diameter of the filament 5, so that this through the grooves 3, 4 and the cover plate 6 is fixed in position.
- the filament is 5 in the part of its course that is behind the base plate 1 is shown in dashed lines. The location of the holes results itself from the transitions from solid to dashed Representation of the filament 5.
- the filament 5 is powered by a power supply (not shown) operated directly to the two Ends 7, 8 of the filament can be connected.
- a car battery can also be used as a voltage source be, so that it is possible, the device shown for the visual display of signs in motor vehicles to accommodate.
- the device can, for example by means of suction cups on the rear window of a motor vehicle be attached while the base plate 1 with any Groove shapes can be provided, in each of which a filament of the type mentioned can be inserted.
