#1. 淺談影響LED元件熱阻的因素
LED 的熱阻是指LED點亮後，熱量傳導穩定時，晶片表面每1W耗散，PN結點的溫外與連線的支加或散熱基板之間的溫度差就是LED的熱阻Rth。熱阻值一般常用θ或 ...
#2. 電晶體是什麼？ 元件溫度計算方式
Rth （j-a）為250ºC/W，功耗每增加0.1W，接合處溫度則增加25ºC。功耗為0.5W時，接合處溫度則為150ºC。此例子中，可得知不會增加0.5W以上的功率。
#3. LED可靠度驗證
熱阻(Rth)與Tj估算: LED產品對於熱的敏感度很高，且環境越熱將使衰減速度加快，因此必須搭配較佳的散熱設計。熱阻量測有助於客戶尋找適當的散熱模式或者選擇適當的 ...
