Light-emitting module

A light emitting module comprising:

• a driving unit disposed on the substrate to be adjacent to one side of the substrate;
• a first light emitting unit disposed adjacent to another side of the substrate and disposed on one surface of the substrate;
• a second light emitting unit disposed adjacent to the other side of the substrate, disposed on another surface of the substrate, and configured to emit light having a wavelength different from that of the first light emitting unit;
• and
• a reflecting portion configured to surround the first emitting unit and the second light emitting unit and including a first region and a second region facing the first emitting unit and the second light emitting unit,
• wherein each of the first emitting unit and the second light emitting unit includes at least one light emitting chip,
• wherein the first region and the second region include a plurality of sub regions having a parabolic curve with respect to the light emitting chip of each of the first emitting unit and the second light emitting unit,
• wherein the reflecting portion inch ides a plurality of facets,
• wherein the reflecting portion includes an emission surface through which light is emitted, and has a width which gradually increases in a direction of the emission surface,
• wherein the plurality of facets are disclosed in each of the plurality of sub regions, wherein the facets adjacent to each other have different inclination angles with respect to a first direction which is perpendicular to or parallel to the one surface of the substrate.
