Abstract
A semiconductor indicating arrangement comprises a structured contact strip on which are mounted a plurality of luminescent semiconductor elements connected by one electrode to the contact strip and connected by their other electrode to another part of the contact strip, a homogeneous plastic substance embedding the semiconductor element and the contact strip except for outer connecting parts thereof and forming a base and a light conductor above each semiconductor element and a covering casing surrounding the base of the light conductors.
Claims19
A semiconductor arrangement for indicating digits by means of semiconductor illuminating components, characterized in that the illuminating components are arranged on a structured contact strip and are electrically connected to parts of said contact strip;
- that said contact strip is embedded in a homogeneous plastic substance with the exception of the outer connecting parts, said plastic substance forming a baseplate having plate-shaped extensions running perpendicular to the baseplate, wherein said plate-shaped extensions acting as light conductors are arranged over said illuminating components;
- that a casing hood is provided for terminating the whole arrangement, said casing hood being provided with a filter plate as a covering plate;
- and that said covering hood has separating webs running perpendicular to the baseplate on the inside, the separating webs being constructed so that they screen the light conductors from one another.
A semiconductor arrangement for indicating digits by means of semiconductor illuminating elements, characterized in that the illuminating elements are arranged on a structured contact strip and are electrically connected to parts of said contact strip;
- that said contact strip is embedded in a homogeneous plastic substance with the exception of the outer connecting parts, said plastic substance forming a baseplate having plate-shaped extensions running perpendicular to the baseplate, wherein said plate-shaped extensions acting as light conductors are arranged over said illuminating elements;
- that narrow webs running along said supported base plate for supporting said light conductors on their inner side with respect to one another are provided;
- and that a casing hood is provided for terminating the whole arrangement, said casing hood being provided with a filter plate as a covering plate.
A semiconductor arrangement for producing illuminated characters comprising:
- a structured contact strip;
- a plurality of liminescent semiconductor elements mounted on the strip for electrical connection therewith by first electrodes;
- means connecting second electrodes of said semiconductor elements to another part of said strip;
- a homogeneous plastic material embedding said contact strip and said semiconductor elements, but leaving outer connecting parts protruding, and forming a common base plate and a separate light conductor above each said semiconductor element, with each said light conductor extending substantially perpendicular to said base plate;
- and a casing hood surrounding said base plate and said light conductors, said casing hood having a plurality of inner webs which extend perpendicular to said base plate between said light conductors to screen same from one another.
