| 英文摘要 | PURPOSE:To prevent a semiconductor laser light source from being abnormally heated and to protect the light source by interrupting a heat source for heating the semiconductor laser light source by means of a protective circuit when the value of a detected electric resistance exceeds a predetermined reference value. CONSTITUTION:The environmental temperature of a semiconductor laser light source 1 during operation is continuously detected, and fed to a temperature detector 1 The detector 11 generates a detection signal on the basis of a detected value, and fed together with a reference signal set to a predetermined value, generated from a temperature reference signal generator 12 to a comparator 13. The detection signal is compared with the reference signal, and when the environmental temperature of the source 1 indicated by the detection signal becomes lower than the desired temperature of the source 1 indicated by the reference signal, a signal for operating a heater driver 14 is generated from the comparator 13. Thus, when the source 1 is heated by a heater 7 so that the temperature of the source 1 is raised to a predetermined temperature, the comparator 13 stops generating the signal, and the heater 7 is stopped in its operation. |
