- W2562770670 abstract "An ac or dc GaP LED array has been designed and fabricated which has potential as a direct replacement for several tungsten filament lamps and as an illuminator for new design considerations. In designing such an LED for high voltage application, series light emitting junctions rather than series resistors are used as a voltage divider to maximize the light output/power input ratio. A figure of merit is modeled and calculated which provides a measure of total light output for a given applied current and voltage as a function of the number of series diodes. P-n junctions on the same chip were electrically isolated utilizing either proton bombardment or chemically etched trenches. A Au metallization scheme provides the series-parallel interconnection required for ac or dc operation while maintaining junction isolation. The light emitting junction areas are mesas, with edges shaped to redirect internally generated light out to the viewer." @default.
