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.
