Abstract
A method of manufacturing a light emitting module includes: providing an intermediate that includes a light guide having a first principal face and a second principal face opposing the first principal face, a plurality of light sources disposed on the second principal face of the light guide, and a wiring layer disposed on the second principal face and electrically connected to the plurality of light sources; allowing the plurality of light sources to emit light and measuring optical characteristics of the emitted light; and forming an optical characteristic correcting element in the intermediate based on the measured optical characteristics.

A method of manufacturing a light emitting module comprising:
- providing an intermediate, the intermediate including:
- a light guide having a first principal face and a second principal face opposing the first principal face,
- a plurality of light sources disposed on the second principal face of the light guide, and
- a wiring layer disposed on the second principal face and electrically connected to the plurality of light sources;
- allowing the plurality of light sources to emit light and measuring optical characteristics of the emitted light;
- and
- forming an optical characteristic correcting element in the intermediate based on the measured optical characteristics.
A method of manufacturing a light emitting module comprising:
- providing an intermediate, the intermediate including:
- a wiring substrate,
- a light guide having a first principal face and a second principal face opposing the first principal face, wherein the light guide is disposed so as to face the wiring substrate, and in the light guide, a plurality of first holes extend through from the first principal face to the second principal face, and
- a plurality of light sources disposed on the wiring substrate in the first holes;
- allowing the plurality of light sources to emit light and measuring the optical characteristics of the emitted light;
- and
- replacing, based on the measured optical characteristics, one of the plurality of light sources with other one of the plurality of light sources on the wiring substrate.
