摘　　要：针对光源与温控电路匹配问题,开展了光源组件特性的理论和试验研究,分析了影响两者匹配的原因及解决办法。研究结果表明:光源内部组件——半导体制冷器等效内阻RTEC、温控电流ITEC、TEC制冷/加热效率ε和热敏电阻温度系数β,是影响光源与温控电路匹配的主要因素;光源内部各组件特性受自身特性、工艺、散热条件和环境温度等多种因素影响,导致光源与温控电路的匹配也受相应因素影响;当散热充分时,光源与温控电路的匹配特征可近似用RTEC、β、SLD功率PSLD和ITEC表征;在接近光源实际散热条件下进行匹配测试,可提高光源与温控电路的匹配度,减少后期不匹配几率;不同批次、不同厂家生产的光源的组件特性差异较大,重新匹配和调整温控电路参数,可大幅提高光源利用率。Aim at the poor matching between SLD and its temperature control cucuits,the theoretical and experimental investigations on SLD characteristics were done.The factors affecting the matching and the resolvents were also analyzed.Results indicate that：（1） the main factors are the equivalent resistence of TEC（RTEC）,cooling/heating efficiency of TEC（ε）,temperature control current（ITEC）and temperature coefficient of thermistor（β）;（2） the above parameters are affected by the SLD characteristics,process,cooling conditions,ambient temperature,etc.（3） the matching properties can be characterized by RTEC,β,power of SLD（PSLD）,and ITEC;（4） If SLDs are tested under approximate practical conditions,the matching between SLD and its temperature control cucuits can be improved;（5） For the SLDs from different batches or manufactories,adjustments of the paramaters of the temperature control cucuits may greatly improve SLD＇s using efficiency.
