Abstract

The invention relates to a method for producing a high-efficiency light-emitting device and a high-efficiency light-emitting device. The method for producing the light-emitting device (100) consists of installing a light-emitting element (20) on the bottom surface of the defined cavity (15) of the package (10); forming the first reflective layer (30) by the first plastic layer containing the first reflective material to cover the side surface of the defined cavity (15); forming the second reflective layer (40) by the second plastic layer containing the second reflective material to cover the bottom surface of the defined cavity (15); and arrange the light-transmitting layer (50), in which the third plastic layer contains phosphorus, on the second reflective layer (40) and the light-emitting element (20), in which at the step of forming the second reflective layer (40), the layer containing (40a) the second reflective material and the light-transmitting layer (40b) are formed on the bottom surface of the determined cavity (15) according to the method of moving the second reflective material in the second plastic layer by centrifugal force while forming the second reflective layer (40) so that the layer containing (40a)
