Abstract:
1. A lighting device comprising: an inorganic first light emitting diode (LED) having a first top LED conducting surface and a first bottom LED conducting surface, the first LED being a vertical first LED, the first LED having an epitaxially grown n-type layer and an eptiaxially grown p-type layer between the first top LED conducting surface and the first bottom LED conducting surface; and a vertical first transistor in series with the first LED, the first transistor having a first terminal, a second terminal, and a third terminal, the first terminal being a bottom conducting surface of the first transistor, the bottom conducting surface of the first transistor opposing the first top LED conducting surface and being electrically and mechanically bonded to the first top LED conducting surface, the first transistor having a top surface, wherein the second terminal and third terminal are formed on the top surface, the bonded first LED and vertical first transistor being singulated together such that the first transistor is substantially the same size as the first LED, the first LED being configured to emit light when a first voltage is applied to the first bottom LED conducting surface, a second voltage is applied to the second terminal, and a first control voltage is applied to the third terminal.
