Light emitting device for transmission of communications information
A light emitting device 1 is adapted, with a distributed power supply voltage, to turn on a light emitter 7, while timing a continuous conduction time with a pulse generating circuit 2, a frequency dividing circuit 3, and a counting memory circuit 4, to flash the light emitter 7 on and off with an on-off pattern depending on a result of the timing, signaling out information on the continuous conduction time.
