Description
(2.0MPaにおけるaの平均値)=X×2.0(MPa)+Y
(3.0MPaにおけるaの平均値)=X×3.0(MPa)+Y
となる。切片bの方程式は、
(2.0MPaにおけるbの平均値)=X'×2.0(MPa)+Y'
(3.0MPaにおけるbの平均値)=X'×3.0(MPa)+Y'
となる。これらの方程式を解いて、X、Y、X'、Y'を求めることができる。
a=−0.38×P+1.79
b=−3.32×P+24.3
とすることができる。したがって、傾きaと、切片bと、内圧Pと、シール用ガラス部材の径Dと、発光管球面の端から封止部の先端までの距離L1との関係式は、
D=a×L1+b
=(−0.38×P+1.79)×L1+(−3.32×P+24.3)
と表すことができる。
D<(−0.38×P+1.79)×L1+(−3.32×P+24.3)
の範囲であれば、ランプは破裂しないといえる。ランプ投入電力が5〜25kWのランプに渡って、このことが確かめられたことにより、この範囲に入るすべてのランプに、この結果が適用できることは明らかである。
