A method for producing a light emitting diode device includes the steps of preparing a base board; allowing a light semiconductor layer where an electrode portion is provided at one side in a thickness direction to be disposed in opposed relation to the base board, and the electrode portion to be electrically connected to a terminal, so that the light semiconductor layer is flip-chip mounted on the base board; forming an encapsulating resin layer containing a light reflecting component at the other side of the base board so as to cover the light semiconductor layer and the electrode portion; removing the other side portion of the encapsulating resin layer so as to expose the light semiconductor layer; and forming a phosphor layer formed in a sheet state so as to be in contact with the other surface of the light semiconductor layer.

A phosphor ceramic includes at least one fluorescent layer that is capable of emitting fluorescent light; and at least one non-fluorescent layer that does not emit fluorescent light and is laminated onto the fluorescent layer.
摘要:
A reflecting resin sheet provides a reflecting resin layer at the side of a light emitting diode element and includes a first release substrate and the reflecting resin layer provided on one surface in a thickness direction of the first release substrate. In the first release substrate and the reflecting resin layer, a through hole extending therethrough in the thickness direction is formed corresponding to the light emitting diode element so as to allow an inner circumference surface of the through hole in the reflecting resin layer to be disposed in opposed relation to a side surface of the light emitting diode element.
