Abstract
【解決手段】投光構造体10は、頂点t近傍に焦点fが位置する深い凹面に形成された反射面11aを有する反射部材11と、前記焦点t及びその周辺に配置され、励起光により励起されることにより光を出射する発光部材12と、を有する。
【選択図】図1
Description
図1は、本発明の投光構造体の一例を示す概略図である。図1に示すように、本発明の投光構造体10は、頂点t近傍に焦点fが位置する深い凹面に形成された反射面11aを有する反射部材11と、焦点f及びその周辺に配置され、励起光により励起されることにより光を出射する発光部材12と、を有する。ここで、反射部材11の反射面11aは、放物面に形成されているものとする。
次に、本発明の投光構造体を用いた照明装置の実施形態を説明する。
上記実施形態の照明装置によると、白色光を略平行光として投光することが出来る。従って、移動体用の前照灯として利用価値が高い。ここでいう移動体としては、自転車、乗用車、鉄道等の車両の他、航空機、船舶、潜水艇等が含まれる。
上記の実施形態では、本発明の投光構造体に用いる反射部材は、放物面の反射面を有するものとして説明してきたが、本発明が適用される反射部材はこれには限定されず、頂点近傍に焦点を有する深い凹面の反射面を有するものであれば同様に適用が可能である。また、放物面を複合した反射面を有する反射部材を用いることも出来る。例えば、CPC(Compound Parobora Consentrator)型のミラーを用いることが出来る。
10、20、30、40、50 導光構造体
11、21、31、41、51 反射部材
12、22、32、42、52 発光部材
13、43 半導体レーザ素子(励起光源)
