Abstract
A method of fabricating a light-emitting device including the steps of forming a first resin including a phosphor on a light-emitting diode chip mounted on a package body, measuring color coordinates of light emitted by combination of the light-emitting diode chip and the phosphor, correcting the color coordinates by forming a second resin on the first resin, and curing the first resin and the second resin after correcting the color coordinates, in which the first resin is not fully cured before measuring and correcting the color coordinates.
Claims18
A method of fabricating a light-emitting device, the method comprising:
- forming a first resin comprising a phosphor on a light-emitting diode chip mounted on a package body;
- measuring color coordinates of light emitted by combination of the light-emitting diode chip and the phosphor;
- correcting the color coordinates by forming a second resin on the first resin;
- and
- curing the first resin and the second resin after correcting the color coordinates,
- wherein the first resin is not fully cured before measuring and correcting the color coordinates.
The method of claim 11, wherein the second resin is formed on the first resin in the cavity such that a molding section becomes coplanar with an upper surface of the cavity.
A method of fabricating a light-emitting device, the method comprising:
- depositing a first resin comprising a phosphor on a light-emitting diode chip mounted on a package body;
- allowing the phosphor of the first resin to settle around the light-emitting diode chip after depositing the first resin on the light-emitting diode chip;
- measuring color coordinates of light emitted by combination of the light emitting diode chip and the phosphor;
- and
- correcting the color coordinates by forming a second resin on the first resin,
- wherein the concentration of the phosphor gradually decreases towards an upper surface of the first resin.
A method of fabricating a light-emitting device, the method comprising:
- forming a first resin comprising a phosphor on a light-emitting diode chip mounted on a package body;
- measuring color coordinates of light emitted by combination of the light-emitting diode chip and the phosphor;
- and
- correcting the color coordinates by mixing a phosphor-containing or phosphor-free second resin with the first resin,
- wherein the first resin is not fully cured before measuring and correcting the color coordinates.
