Description
Q=F・ε・σ・(T2 4−T3 4)・A (1)
但し、Fは形態係数であって、0<F<1、
εは光源1もしくは放熱基板2の放射率であって、0<ε<1、
σはステファン・ボルツマン定数(W/m2・K4)、
T2は光源1もしくは放熱基板2の絶対温度(K)、
T3は光学レンズ3の絶対温度(K)、
Aは伝熱面積(m2)
である。尚、形態係数Fは放射熱の計算において放射熱をやり取りする2つの面間の幾何学的位置関係を表す量であって、たとえば、2つの面の向きが平行平面のときにはF=1に近づき、他方、2つの面の向きが直角に近く、2つの面の投影面積が小さい程F=0に近づく。従って、図1においては、光源1、放熱基板2と光学レンズ3とが平行であり、互いの干渉が大きくなり、この結果、光源1、放熱基板2と光学レンズ3との間の形態係数Fは1に近づく。
