Patent Images
1. A method for manufacturing a light emitting apparatus, the method comprising steps of:
- mounting a plurality of light emitting elements on a substrate;
applying a resin containing phosphors to form wavelength conversion units covering the plurality of light emitting elements on the substrate;
removing portions of the wavelength conversion unit between the plurality of light emitting elements; and
dicing regions of the substrate, from which the portions of the wavelength conversion unit have been removed, to separate the plurality of light emitting elements into individual light emitting elements.

Abstract
The present application provides for a method for manufacturing a light emitting apparatus. The method includes mounting light emitting elements on a substrate and applying a resin containing phosphors to form wavelength conversion units covering the light emitting elements on the substrate. Portions of the wavelength conversion unit are removed between the light emitting elements. Regions of the substrate are diced, from which the wavelength conversion unit have been removed, to separate the plurality light emitting elements into individual light emitting elements.
