This creation system discloses a kind of light wave sterilizing device, is to have one of two wearing portions object to be sterilized using what, which includes an ontology and a light source unit. The ontology has a pedestal and two euphotic supports, which is arranged the what pedestal and has simultaneously defined an accommodating area with the pedestal, the grade euphotic supports what against what this etc. between wearings portion; The light source unit is arranged the what ontology, which includes an at least light-emitting component and a circuit board, the light-emitting component system and the circuit board electrical connection, between the light-emitting component position what equal euphotic supports simultaneously in the position what accommodating area. Thereby, the light wave sterilizing device of this creation may achieve the effect of wearing portion for object to be sterilized is sterilized and has both the placement rack as object to be sterilized.本創作係揭露一種光波殺菌裝置,係應用於具有二配戴部之一待殺菌物,該光波殺菌裝置包含一本體及一光源單元。該本體具有一基座與二透光支撐件,該等透光支撐件設置於該基座並與該基座界定有一容置區,該等透光支撐件用於抵靠於該等配戴部之間;該光源單元設置於該本體,該光源單元包含至少一發光元件與一電路板,該發光元件係與該電路板電連接,該發光元件位於該等透光支撐件之間並位於該容置區內。藉此,本創作之光波殺菌裝置,可達成針對待殺菌物之配戴部進行殺菌並兼具作為待殺菌物之放置座的功效。
