ABSTRACT:
A light emitting device1is adapted, with a distributed power supply voltage, to turn on a light emitter7, while timing a continuous conduction time with a pulse generating circuit2, a frequency dividing circuit3, and a counting memory circuit4, to flash the light emitter7on and off with an on-off pattern depending on a result of the timing, signaling out information on the continuous conduction time.
