Use [challenge] phosphorescent material, it is possible to more long-term phosphorescent by the brightness of the release, insect traps effect even in the absence of a power supply is to provide a light source device obtained longer. An LED element that emits visible light An ultraviolet LED element emitting ultraviolet rays having a wavelength of 300 nm to 400 nm and the wavelength 440nm~660nm to one or plural combination light source, transmitted through the ultraviolet, was contained phosphorescent material characterized in that the covered cover the polycarbonate resin cover to the light source unit. .FIELD 1【課題】蓄光材を使用して、より長時間の蓄光による明るさの放出が可能となり、無電源下でも捕虫効果がより長く得られる光源装置を提供する。【解決手段】波長300nm~400nmの紫外線を発光する紫外線LED素子と波長440nm~660nmの可視光を発光するLED素子を単数または複数個組み合わせた光源に、紫外線を透過し、蓄光材を含有させたポリカーボネート樹脂カバーを光源部に覆いかぶせたことを特徴とする。【選択図】図1
