Abstract
PURPOSE: To limprove the SN ratio with increased peak value of optical pulse, by flowing the drive current to light emitting diode once at a half period with specific phase of AC power input.
CONSTITUTION: The load 3 is connected to the AC power input 4 via the full wave rectifying circuit 13 and the switching element 12. DC power is fed to the projector 1 via the full wave rectifying circuit 13' from the AC power supply 4', and the charge in the capacitor 22 illuminates the light emitting diode 6 with turning on of the thyristor 24. This light is received with the photo detection diode 7 to turn on thetransistors 45, 46 of the amplifying circuit 8 and trigger circuit 10 and to turn on the switching element 12.
