Abstract
A light source apparatus according to an embodiment of the present technology includes a plurality of light source portions, a plurality of temperature adjustment units, and a drive control unit. The plurality of temperature adjustment units are capable of respectively adjusting temperatures of the plurality of light source portions. The drive control unit is capable of controlling a drive timing of each of the plurality of temperature adjustment units.
Claims12
A system for controlling temperatures of a plurality of light source portions, the system comprising:
- the plurality of light source portions;
- a plurality of temperature adjustment units configured to adjust the temperatures of the plurality of light source portions;
- and
- a drive control unit configured to:
- adjust a temperature of a first light source portion of the plurality of light source portions;
- and
- adjust a temperature of a second light source portion of the plurality of light source portions that is different from the first light source portion based on the temperature of the first light source portion that is within a threshold range.
A system for controlling temperatures of a plurality of light source portions, the system comprising:
- the plurality of light source portions;
- a plurality of temperature adjustment units configured to adjust the temperatures of the plurality of light source portions;
- a temperature detection unit configured to detect a temperature of each of the plurality of light source portions;
- and
- a drive control unit configured to control, by a Proportional Integral Derivative (PID) process, each of the plurality of temperature adjustment units based on the temperature detected by the temperature detection unit.
A method for controlling temperatures of a plurality of light source portions, the method comprising:
- detecting a temperature of each of a plurality of temperature adjustment units configured to adjust the temperatures of the plurality of light source portions;
- and
- controlling, by Proportional Integral Derivative (PID) process, each of the plurality of temperature adjustment units based on the detected temperature of each of the plurality of temperature adjustment units.
