英文摘要 | Disclosed is a laser driving device which enables to reduce unnecessary power consumption. The laser driving device comprises a laser driving unit for supplying a driving current for having a semiconductor laser emit a light, a temperature sensing unit for sensing the temperature of the semiconductor laser, and a voltage controlling unit for supplying a power supply voltage to the laser driving unit which outputs a voltage changed according to the temperature sensed by the temperature sensing unit. With this structure, unnecessary power consumption can be reduced. An apparatus employing such a laser driving device can achieve energy-saving and can suppress increase in temperature of the apparatus. |
