Light-emitting diode with different light output levels for vehicle rear braking light - uses integrated resistance with different resistance terminals providing respective resistance values for controlling light level

摘要

The light-emitting diode has integrated resistances for obtaining the different light outputs formed on a single semiconductor chip. The diode has a single or double heterostructure formed in the clip surface (2), the thin-film resistance (5b) having a number of resistance terminals (8, 9, 10) for providing a corresponding series of resistance values, used to obtain the different light output levels. ADVANTAGE - Normal single or double heterostructure and etching processes are used to produce resistor regions.
