熱參數(shù)是衡量 LED性能的關(guān)鍵指標(biāo)。LED在不同溫度條件下工作，對(duì)于LED的光參數(shù)、色參數(shù)、電參數(shù)、壽命等其它參數(shù)都有重大影響。因此，對(duì)于LED生產(chǎn)廠家、應(yīng)用廠家，如何對(duì)LED進(jìn)行合理的散熱設(shè)計(jì)是至關(guān)重要的。JDS200參照相關(guān)標(biāo)準(zhǔn)，對(duì)LED的光、色、電、熱進(jìn)行綜合測(cè)試，并描繪各參數(shù)隨時(shí)間的變化曲線，使設(shè)計(jì)人員的工作變得輕輕松松。
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.
