Abstract

A method for manufacturing a light-emitting device includes: providing first and second substrates each including a plurality of packages, the packages each having a recess and a light-emitting element mounted in the recess; performing potting by supplying a resin member containing particles of a fluorescent material into the recess of each of the packages of the first substrate; spreading the resin member in the recess of each of the packages of the first substrate; measuring a height of an upper surface of the resin member spread in the recess of at least one of the packages of the first substrate; and adjusting a quantity of the resin member to be supplied into the recess of each of the packages of the second substrate depending on the measured height of the upper surface of the resin member.

Claims (14)

1. A method for manufacturing a light-emitting device, the method comprising:

providing a first substrate and a second substrate each including a plurality of packages, the packages each having a recess and a light-emitting element mounted in the recess;

performing potting by supplying a resin member containing particles of a fluorescent material into the recess of each of the packages of the first substrate;

heating the resin member at a temperature of about 30° C. to 50° C. to lower a viscosity of the resin member so that the resin member spreads in the recess of each of the packages of the first substrate;

measuring a height of an upper surface of the resin member spread in the recess of at least one of the packages of the first substrate; and

adjusting a quantity of the resin member to be supplied into the recess of each of the packages of the second substrate depending on the measured height of the upper surface of the resin member spread in the recess of the at least one of the packages of the first substrate.

2. The method for manufacturing a light-emitting device according to claim 1 , wherein

the resin member includes a silicone resin composition.

3. The method for manufacturing a light-emitting device according to claim 1 , wherein

the resin member includes 1 part by weight to 200 parts by weight of the fluorescent material.

4. The method for manufacturing a light-emitting device according to claim 1 , wherein

the measuring of the height of the upper surface of the resin member being performed by using a measuring part disposed above the recess.

5. The method for manufacturing a light-emitting device according to claim 4 , wherein

the measuring of the height of the upper surface of the resin member includes measuring a distance between the upper surface of the resin member and the measuring part as the height of the upper surface of the resin member.
