Folder with detachable illumination device

Abstract

A folder has a detachable illumination device disposed on an upper cover of the folder so that the illumination device, such as a lamp, can be momentarily inserted into a specific power socket to provide illumination, or can be detached and placed in a predetermined slot formed on an inner surface of the folder to facilitate the carrying. Thus, the folder can break the limitation in use in various occasions where no sufficient light source is provided, and can thus enhance the utility and the convenience thereof.
