As shown in FIG. 5, in the second state, the first movable end 222 of the flexible reflective sheet 220 is adjacent to the frame 230, and the flexible light guide plate 250 is unfolded and the second movable end 252 and the light source L are away from the frame. 230. In the second state, the illumination device 20 exhibits the double-sided illumination Lds, because at this time, the reflective sheet is not disposed under the flexible light guide plate 250, and the light source L located on one side of the flexible light guide plate 250 generates the light Lo to enter the flexible state. The light guide plate 250, and the light beam Lo passes through the transmission path Lw in the flexible light guide plate 250 to emit the upper surface and the lower surface of the flexible light guide plate 250 to generate the double-sided light emission Lds. As shown in FIG. 6 , in the third state, the flexible light guide plate 250 is unfolded and the second movable end 252 and the light source L are away from the frame 230 , and the flexible reflective sheet 220 is also deployed on the flexible light guide plate 250 . The first movable end 222 is away from the frame 230 and is fixed to the reflective cover 260 of the second movable end 252. In the third state, the illumination device 20 exhibits a single-sided illumination Lss because the flexible reflective sheet 220 is unfolded under the flexible light guide plate 250, and the light source L located on one side of the flexible light guide plate 250 is generated. Light Lo, and The light ray Lo advances through the transmission path Lw in the flexible light guide plate 250 and is reflected by the flexible reflective sheet 220 to the upper surface of the flexible light guide plate 250 to generate a single-sided light emission Lss. In this embodiment, the first shaft 210a and the second shaft 210b may be a manual shaft or an automatic shaft, but are not limited thereto. The manual shaft winds the flexible reflection sheet 220 and the flexible light guide plate 250 on the first shaft 210a and the second shaft 210b, respectively, by using a manual rotation shaft. The automatic shaft sets a motor switch assembly (not shown) on the first shaft 210a and the second shaft 210b, and provides a power drive switch to control the deployment of the flexible reflector 220 and the flexible light guide plate 250. With the volume, but not limited to this.
如上述所述，本發明之第一實施例及第二實施例係分別利用導光板與可撓式反射片以及可撓式導光板與可撓式反射片之組合，使得照明裝置兼具單面發光以及雙面發光之特性，亦提升照明裝置之應用範圍。舉例而言，將本發明第一實施例之照明裝置設置於屋頂之天窗，白天時，在照明裝置之第一狀態下且光源關閉，係利用太陽光之光線透過導光板之折射提供室內足夠的光線；夜晚時，在照明裝置之第一狀態下且光源開啟，係利用單面發光之照明裝置提供室內照明的光線，但不限於此。As described above, the first embodiment and the second embodiment of the present invention respectively use a light guide plate and a flexible reflection sheet, and a combination of the flexible light guide plate and the flexible reflection sheet, so that the illumination device has a single side The characteristics of illumination and double-sided illumination also enhance the application range of the lighting device. For example, the illuminating device of the first embodiment of the present invention is disposed on the roof skylight, and during the daytime, in the first state of the illuminating device and the light source is turned off, the illuminating light passing through the light guide plate is used to provide sufficient indoor space. Light; at night, in the first state of the illumination device and the light source is turned on, the illumination of the indoor illumination is provided by the illumination device with single-sided illumination, but is not limited thereto.
以上所述僅為本發明之較佳實施例，凡依本發明申請專利範圍所做之均等變化與修飾，皆應屬本發明之涵蓋範圍。The above are only the preferred embodiments of the present invention, and all changes and modifications made to the scope of the present invention should be within the scope of the present invention.
