3-TERMINAL LIGHT EMITTING DEVICE AND LIGHTING CIRCUIT OF USING THE SAME

摘要

PURPOSE: A three-terminal light emitting device and a lighting circuit using the same are provided to form an efficient lighting circuit. CONSTITUTION: Two anodes(160,180) are arranged to face in opposite direction around a common cathode(170). Two light emitting bodies are arranged in a reverse direction between the two anodes while facing each other. The light emitting bodies are connected to the common cathode which is one electrode. Forward current is applied to at least one light emitting body which is connected to the common cathode.
