摘要	A light source device 100 includes: multiple semiconductor laser light sources 101; a base plate 102 having thereon an installation area on which the multiple semiconductor laser light sources 101 are installed and which is divided into multiple areas, thus dividing the multiple semiconductor laser light sources 101 on the installation area into the multiple groups such that each of the groups includes one of the multiple semiconductor laser light sources 101 or at least two of the semiconductor laser light sources 101 that are electrically connected in series; and a current control section 109 configured to conduct temperature control of the semiconductor laser light sources 101 by independently controlling a value of current flowing in each of the groups of the multiple semiconductor laser light sources 101 on the installation area.
其他摘要	光源装置100包括：多个半导体激光光源101;底板102上具有安装区域，在该安装区域上安装有多个半导体激光光源101并且该底板102被分成多个区域，从而将安装区域上的多个半导体激光光源101分成多个组，使得每个这些组包括多个半导体激光光源101中的一个或者至少两个串联电连接的半导体激光光源101;电流控制部分109，用于通过独立地控制在安装区域上的多个半导体激光光源101的每组中流动的电流值来进行半导体激光光源101的温度控制。
