PROBLEM TO BE SOLVED: To provide a light source device which is an LED light source device emitting ultraviolet rays, and uses a diffusion part subjected to a treatment for diffusing ultraviolet rays to a light source side for a bug to perceive the light source as a sufficiently bright light source.SOLUTION: The light source device using an LED element for the light source discharges ultraviolet rays through the diffusion part subjected to a diffusion treatment for ultraviolet rays emitted from the LED element. The light source device includes a light source part mounted with a single LED element or a plurality of LED elements of different wavelengths in combination, a control part for controlling the output of the LED elements of the light source part independently, and a power supply part for supplying power to the light source part and the control part. The LED elements include an LED element emitting at least one or more ultraviolet rays. The LED element that emits ultraviolet rays has wavelength characteristics of a wavelength of 320-420 nm or less. The light source device is subjected to a diffusion treatment for diffusing ultraviolet rays, and performs either linear emission or planar emission.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2016,JPO&INPIT【課題】紫外線を発光するLED光源装置であって、虫にとって十分に明るい光源として認識できるよう、光源側に紫外線を拡散させるための処理を施した拡散部を用いた光源装置を提供する。【解決手段】LED素子を光源に使用した光源装置であって、当該LED素子から発光される紫外線の拡散処理を施した拡散部を通して、紫外線を放出する光源装置。波長の異なるLED素子を単数もしくは複数個組み合わせて実装した光源部と、前記光源部のLED素子をそれぞれ独立して出力を制御する制御部と、当該光源部及び制御部に電力を供給する電源部とを備え、前記LED素子には少なくとも1つ以上の紫外線を発光するLED素子が含まれており、当該紫外線発光LED素子の波長は320nmから420nm以下の波長特性を有している光源装置でかつその光源装置に紫外線を拡散させる拡散処理が施し線発光もしくは面発光を特徴とする。【選択図】図1
