Abstract
A method of manufacturing a light emitting module according to the present disclosure includes: preparing a light guide plate that comprises a first main surface serving as a light-emitting surface and a second main surface opposite to the first main surface; respectively providing light emitting elements on the second main surface so as to correspond to each of a plurality of optically functional portions provided on the first main surface of the light guide plate; and forming wires electrically connecting the plurality of light emitting elements.
Claims26
A light emitting module comprising:
- a light guide plate comprising a first main surface serving as a light-emitting surface and a second main surface opposite to the first main surface, the first main surface comprising optically functional portions each consisting of a concave portion with an inclined surface;
- a light diffusing portion or a wavelength conversion portion disposed in the concave portion and having a width smaller than a diameter of an opening of each of the optically functional portions;
- a plurality of light emitting elements, each being joined to the light diffusion portion or a wavelength conversion portion;
- and
- a sealing member sealing each of the light emitting elements and the second main surface of the light guide plate.
