Abstract
【解決手段】紫外線発光装置1は、実装基板2と、複数個の紫外LEDチップ3と、枠体4と、窓材5とを備える。紫外線発光装置1は、光軸に対する紫外線の放射角度をθ、放射角度θの方向の放射光強度をIθとし、放射角度θの範囲を、−90°〜90°のうち0°を含む第1規定範囲、絶対値が前記第1規定範囲内の値よりも大きい第2規定範囲とに分けたときに、放射光強度Iθの放射角度依存性が、cosnθ(nは1以上の実数)を同一出力の基準として、前記第1規定範囲ではcosnθよりも小さくなり、前記第2規定範囲ではcosnθよりも大きくなるように、前記複数個の紫外LEDチップ3が、実装基板2の一表面のうち平面視で枠体4により囲まれた領域2aにおいて、領域2aの中心2aaを避けて且つ中心2aaを囲んで配置されている。
