PROBLEM TO BE SOLVED: To sufficiently reduce a time required for precipitation of fluorescent material irrespective of whether or not the fluorescent material has electric charge, and reduce costs.SOLUTION: A light-emitting diode module 10 is formed by precipitating fluorescent material R and fluorescent material G by dielectrophoresis using an electric field around an LED element 1, and depositing the fluorescent material R and the fluorescent material G on the LED element 1. |
