Abstract
Description
透明光源
K/(A-hK) となり、そこではAは線状光源604に進行するパワーで、Kはそれぞれの素子の線状照射で、均一照明には定常数となる。線状光源の全高がHの場合、H x KはAに満たない。すなわち、総放出パワーは導光体へ進行する総パワーより少なくなるのである。導光体へ進行する完全なパワーが照明に使用される場合、H x K = Aである。例示光源では、吸光係数量が限定される限り、少量のパワーの消費で済むように、H x K は僅かにAに満たない状態が保たれる。
q = 1/sqrt ((h-H)^2 + D/K^2) であり、そこでは D = 4 A (A-HK) である。
