熱參數是衡量 LED性能的關鍵指標。LED在不同溫度條件下工作,對于LED的光參數、色參數、電參數、壽命等其它參數都有重大影響。因此,對于LED生產廠家、應用廠家,如何對LED進行合理的散熱設計是至關重要的。JDS200參照國際相關標準,對LED的光、色、電、熱進行綜合測試,并描繪各參數隨時間的變化曲線,使設計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.
