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 1 |
