Abstract

A method for producing a light-emitting diode device includes a step of preparing a sealing layer by sealing in a light-emitting diode with a sealing material; a step of preparing a fluorescent layer by allowing a phosphor-containing resin composition containing phosphor and silicone resin to reach its B-stage; and a step of bonding the fluorescent layer to the surface of the sealing layer.

Claims (3)

1. A method for producing a light-emitting diode device, the method comprising the steps of: embedding a light-emitting diode with a sealing material, to form a sealing layer, applying a phosphor-containing resin composition containing phosphor and silicon resin to a release substrate, then heating the phosphor-containing resin composition to reach B-stage to form a B-stage fluorescent layer, and after performing both the step of forming the sealing layer and the step of preparing forming the B-stage state fluorescent layer, bonding the B-stage state fluorescent layer to the surface of the sealing layer containing the light-emitting diode.

2. The method for producing a light-emitting diode device according to claim 1 , wherein in the step of forming the sealing layer, a housing is placed so as to surround the light-emitting diode, and an interior of the housing is charged with the sealing material, and

in the step of bonding the B-stage fluorescent layer to the surface of the sealing layer, the B-stage fluorescent layer is bonded to both of the surface of the sealing layer and the surface of the housing.
