PROBLEM TO BE SOLVED: To provide a simple device capable of radiating a mixed electromagnetic wave of an ultraviolet ray and a visible ray to solve the problem that if there are compared the case of using only an ultraviolet ray and the case of using both an ultraviolet lamp and a visible light lamp, an insect-attracting effect is higher in the case using both although there is no device for emitting both the ultraviolet ray and the visible ray, and the arrangement of the devices would only enlarge the size.SOLUTION: There are used a plurality of luminous bodies having one or more LEDs for irradiating an electromagnetic wave of a specific wavelength. Of these, the radiation electromagnetic waves of an LED of at least one kind belong to an ultraviolet region. The luminous bodies of a plurality of kinds are arranged in a predetermined rule, and are covered with a cover having an electromagnetic wave diffusing ability.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2017,JPO&INPIT【課題】 紫外線のみの場合と、紫外線ランプと可視光ランプの両方を用いた場合を比べると、両方を用いた場合の方が誘虫効果が大きい。しかし、このように紫外線と可視光の両方を放射する装置はなく、また単に装置を並べても大きくなるだけである。簡単な装置で、紫外線と可視光の混合電磁波を放射できるものを提供する。【解決手段】 特定波長の電磁波を放射するLEDを1又は複数設けた発光体を複数種用い、そのうちの少なくとも1種のLEDの放射電磁波が紫外線領域であり、複数種の発光体は一定の規則で配置され、更にそれらを電磁波拡散能を有するカバーでカバーしたもの。【選択図】 図1
