Abstract
A method of manufacturing a fluorescent silicone film contains: steps of: A. mixing optical silicone and fluorescent powders so as to produce a mixture, and adding liquid to the mixture; B. vacuuming, degassing and feeding the mixture into an accommodation cavity of a mold; C. placing the mold into a planetary centrifugal mixer so as to centrifuge the mixture; D. forming the fluorescent silicone film in the accommodation cavity; and E. solidifying and removing the fluorescent silicone film from the mold. In the step of A, the optical silicone and the fluorescent powders are mixed at a ratio of 100:10 to 100:25. In the step of B, the accommodation cavity is closed after feeding the mixture. In the step of D, the fluorescent silicone film has a silicone layer and a fluorescent powder layer which are formed in the accommodation cavity in a chemical vapor deposition (CVD) manner.
