An irradiation device for guiding sun light into a plant box, where a light collector is carrier on a sun tracking light guider and they are together installed outdoors, the sun light is collected at an entrance of an optical fiber through the light collector, the sun light is guided into a plant box through the optical fiber to irradiate for a plant in the box. As such, the present invention may directly use the guided sun light, and use the light collection function to focus the sun light as a light dot at the entrance of the optical fiber to enable the sun light into the optical fiber. Thus, the device may effectively collect the sun light outsides, and guide the collected sun light through the optical fiber into the plant box to irradiate, thereby the purposes of effectively using the sun light directly on the irradiation for the plant box and energy and carbon saving may be achieved.一種引太陽光於植物箱照明裝置,利用追日引光器搭載集光器並安裝於戶外,將太陽光經由集光器聚於光纖之入口處,太陽光經由光纖導入室內而放光,作為植物箱照明。藉此,使本發明能直接引用太陽光,利用聚光功能將太陽光聚集於一光點於光纖入口處,並使太陽光進入光纖,故此裝置能有效收集屋外之太陽光,並將收集之太陽光線經由光纖導引至植物箱放光,進而可作為一種能有效運用太陽光直接應用於植物箱照明之方法,以達到節能省碳之目的。1‧‧‧追日引光器2‧‧‧追日控制器3‧‧‧集光器4‧‧‧光纖5‧‧‧放光器
