Abstract

Claims (16)

1. A light module comprising:

a circuit substrate; and

a light emitter disposed on the circuit substrate, the light emitter including:

a light source configured to generate light and including a first epitaxial layer, a second epitaxial layer, and an active layer;

an insulation layer covering the light source;

a first electrode electrically connected to the first epitaxial layer;

a second electrode electrically connected to the second epitaxial layer;

a transparent material covering the light source; and

a light guide configured to guide light generated from the light source,

wherein the light guide includes a guide hole, and the transparent material is disposed on the guide hole, and

wherein a refractive index of the light guide is different from that of the insulation layer.

2. The light module of claim 1 , wherein the transparent material has a surface having a convex shape.

3. The light module of claim 1 , wherein the transparent material has a surface having a concave shape.

4. The light module of claim 1 , wherein a direction angle of light emitted from the transparent material is larger than a direction angle of light emitted from the light source.

5. The light module of claim 1 , wherein a luminance of the light emitter is controllable.

6. The light module of claim 1 , wherein at least a region of an upper surface of the transparent material is disposed at a higher elevation than an upper surface of the light guide.
