Title: Light output stabilizer
Inventor: SHIBAGAKI TARO
IPC: H01S5/068
Filed: 1986-01-27
Abstract: PURPOSE:To accurately control the light output of a semiconductor laser against a temperature variation and to obtain a stable light output by controlling a bias current IB and a pulse width IP on the basis of an error signal of an output of a monitoring photodetector and an input pulse through a low pass filter. CONSTITUTION:A pulse current amplitude control regulator 11 controls the amplitude of an input pulse signal IP to generate a driving pulse. A variable bias current source 12 controls a bias current IB. An LD 13 receives the current IB and the driving pulse IP and outputs a light, which is received by a monitor PD 14. After the output signal of the PD 14 is amplified by an amplifier 15, it is applied to one input of a subtractor 16. An input pulse signal IP is amplified, limited in its band by a low pass filter 18, further delayed by a circuit 19, matched in phase with the output signal of the amplifier 15, and applied to the other input of the subtractor 16. Since the current IB and the pulse width IP are controlled by the error signal of the subtractor 15, and the integrated value of the product signal of a weight function of the presence or absence of the pulse, sufficiently accurate control can be performed.

Abstract: PURPOSE:To provide an automatic vending machine illuminating device preventing an illuminator from being turned off even when strong light is temporarily made incident. CONSTITUTION:In the lighting state of the illuminator 8, a period switching part 11 samples illuminance detected by a photoelectric sensor at a sampling period T2 longer than a sampling period T1 for an OFF state and a comparing part 12 compares plural sampling values with a single threshold and decides the switching to the ON state and the OFF state of the illuminator 8. Although the threshold of the comparing part 12 for deciding the ON/OFF state of the illuminator 8 is a single value, switching sensitivity from the ON state to the OFF state can be reduced as compared with the switching sensitivity from the OFF state to the ON state by setting up the sampling period of the ON state longer than that of the OFF state, and even at the time of incidence of temporarily strong light, the illuminator 8 can be maintained at the ON state.
