Abstract
An LED with an internal bypass transistor, particularly suited for use in a series wired LED string to keep the string lit in the event of a failure of an LED. In one embodiment, the collector and/or base of the bypass transistor is used as one terminal of the shunt and the emitter is used as the opposite terminal. The preferred embodiment is to use the collector and emitter terminals only with the base terminal open.
