LIGHT SOURCE DEVICE AND PROJECTOR |
| 摘要 |
A light source device includes a laser element, a temperature sensor adapted to measure the temperature of the laser element, and a control device adapted to control a value of a current supplied to the laser element based on the measurement value obtained by the temperature sensor. Assuming that a maximum value of an output of a laser beam which the laser element can emit without being damaged is a maximum output, the control device controls the current value in accordance with the measurement value so that the output of the laser element does not exceed the maximum output. |

1. A light source device comprising:
a laser element; a temperature sensor adapted to one of directly and indirectly measure the temperature of the laser element; and a control device adapted to control a value of a current supplied to the laser element based on the measurement value obtained by the temperature sensor, wherein assuming that a maximum value of an output of a laser beam which the laser element can emit without being damaged is a maximum output, the control device controls the current value in accordance with the measurement value so that the output of the laser element is one of equal to and lower than the maximum output. |
