摘要： A method and apparatus for controlling the power of laser diodes are provided. The apparatus includes an output voltage sensor, which senses output voltages of at least two laser diodes and outputs the output voltages to an optical power controller. The optical power controller generates control voltages for controlling the at least two laser diodes by performing proportional-integral (PI) control on error voltages between reference voltages and the output voltages received from the output voltage sensor.

摘要： A control method to control a lamp, which is used as a heat generator, including detecting a temperature of lamp, comparing the detected temperature of the lamp with a predetermined reference temperature, turning off a power supply to the lamp when the detected temperature of the lamp exceeds the predetermined reference temperature, and when the lamp stays in a turned-off state for more than a first time amount, supplying a half wavelength pulse to the lamp at intervals according to a second time amount. According to the lamp control method, reducing the inrush of current to the lamp is possible without requiring additional hardware. When applied to electronic apparatuses, the lamp control method reduces maximum value of the inrush of current in the stand-by mode.
