  • Assembling apparatus for a light tunnel
    Patent number: 9405059
    Abstract: A fabricating apparatus for a light tunnel is provided, which comprises a core rod, a fixing block and a moving block. The light tunnel comprises a plurality of reflecting sheets, and each reflecting sheet leans on both a plurality of first bumps of the fixing block and a plurality of second bumps of the moving block to define a first inner profile and a second inner profile of the light tunnel, respectively. Thereby, the fabricating apparatus defines the inner scope of the light tunnel, and the inner scope of the light tunnel can be easily and stably controlled. Furthermore, a fabricating method for fabricating the light tunnel is also provided.
