热参数是衡量 LED性能的关键指标。LED在不同温度条件下工作，对于LED的光参数、色参数、电参数、寿命等其它参数都有重大影响。因此，对于LED生产厂家、应用厂家，如何对LED进行合理的散热设计是至关重要的。JDS200参照国际相关标准，对LED的光、色、电、热进行综合测试，并描绘各参数随时间的变化曲线，使设计人员的工作变得轻轻松松。
Thermal parameter is the key index to evaluate the quality of LED. Different temperature will have significant different effects on optical parameters, color parameters, electricity parameters and life of LED.Therefore,design and control of the thermal dissipation are the most important thing for the manufacturers and users, referring to the relative international standard,JDS200 could conduct integration testing on optic,color,electricity and thermal,meanwhile record the changing curve of the parameters with time.
