Abstract
Description
発光装置の高さが固定値である時に、斜面172A1の傾斜角度(θ)が小さいほど、発光装置の厚み(Y方向)が大きい。発光装置のサイズが大きくなるため、幾つかの分野に応用されにくくなる可能性がある。よって、斜面172A1の傾斜角度を設計する時に、その応用を考慮する必要があり、つまり、任意の角度でも良いとは言えない。
表2から分かるように、D3がD4よりも小さいとき、ΔDの絶対値が大きいほど、発光装置1100の発光角度が大きい。発光装置1100の発光角度は、透光体12を覆わない発光構造11の発光角度に接近することができる。第19図との相違点は、第22B及び第22C図では、斜面172Cの上方が透光体12により覆われ、且つ、第19図における平面172A2を含む部分を有しないことにある。第22B図に示すように、斜面172Cを含む部分が、発光構造11よりも大きい高さを有する時に、発光装置1000が発する光は、斜面172Cを経由して透光体12の上方へ反射されて、発光装置1000を離れることができる。発光構造11の発光角度(例えば、140度)は、斜面172Cにより、発光装置1000の発光角度を小さくさせることができる(例えば、120度)。一方、第22C図に示すように、斜面172Cが、発光構造11よりも小さい高さを有する時に、発光構造11が発する一部の光は、斜面172Cで反射されず、発光装置1100を直接離れるので、発光装置1100の発光角度は、発光装置1000の発光角度よりも大きいが、発光構造11の発光角度よりも小さい(例えば、120度よりも大きく、140度よりも小さい)。斜面のところの部分の高さの設計により、発光装置が異なる発光角度を有すようにさせることができ、これにより、発光装置の応用分野を広げることができる。
