ABSTRACT:
FIELD OF THE INVENTION
The present invention relates to a control and signaling unit or to a signaling unit having a light-emitting element.
RELATED TECHNOLOGY
German Patent Document No. 298 00 780 describes a functional element for a signaling unit having a light-emitting element, the signaling unit being made of a front element and a mounting adapter for locking the functional elements into place. The functional element has a luminous means including a bayonet-catch type mount fixture. An incandescent lamp is used as a luminous means. However, it has the drawback of a service life that is shorter than that of other luminous means, such as of light-emitting diodes. The insulating enclosure is provided with circuit conductors, which are arranged using the (two-component injection molding) production method of MID [molded interconnected device] technology, as described in German Patent Document No. 298 0078.
Furthermore, circuit conductors have been applied using the heat-embossing method, as described in the company prospectus of the 3-D MID e.V. Forschungsvereinigung [Research Association] “Räumliche Elektronische Baugruppen” [Three-Dimensional Electronic Modules] May 1998 , page 13.
It is generally known in signaling units, to use light-emitting diodes. Due to the lower luminosity in comparison to incandescent lamps, it has been necessary to use several, however, at least two light-emitting diodes.
SUMMARY OF THE INVENTION
An object of the present invention is to devise a control and signaling unit, or a signaling unit, having a light-emitting element, which is inexpensive and uncomplicated to manufacture.
The present invention provides a control and signaling unit or a signaling unit having a light-emitting element, comprised of a front element and a mounting adapter for locking the functional elements into place, characterized in that only one light-emitting diode (
3
), including a diode crown (
5
) and connecting wires (
4
), is intergrated in the functional element (
2
), the diode crown (
5
) being embedded and retained in a receptacle (
6
), that the light-emitting diode (
3
) has an angle of radiation of 30-45°, that the light-emitting diode (
3
) has a luminosity of at least 0.5 candela, and that an electronic circuit is arranged on circuit conductors (
11
) secured to the inner housing wall of a housing half (
1
) and applied using a foil heat-embossing process.
