Abstract
Description
RθJ・Ref =(TJ−TRef)/P (式1)
ここで、Pは紫外線発光ダイオード11bの消費電力である。使用する市販のUV−LEDのRθJ・Refが150℃/Wであったとする。0.13WのUV−LEDを80℃以下に保つように冷却するには、上記式1を適用して、
150℃/W=(80℃−TRef)/0.13W
から、TRef=60.5℃となり、よって、ケース表面温度TRefが60.5℃以下になるように冷却する必要がある。
(TRef−TW)/TRef =0.9L (式2)
ここで、L [cm]は冷却棒の長さであり、底「0.9」に対するべき指数となっている。なお、「0.9」は、放熱部12の放熱特性を示す、当該材質に固有の値を例示している。式2の場合、水温が25℃のとき、L=5.06 [cm]となる。この「0.9」の実際値を、放熱部12として使用する金属の材質ごとに実験で求めれば、その放熱部12の長さLを容易に設計できる。
