Classification: CPC A  H  F  Y | IPC A  F

Claim 6:
7. A light module comprising:
a plurality of first light emitters configured to emit a first light having a first peak wavelength in a visible range;
a plurality of second light emitters configured to emit a second light having a waveform having a second peak wavelength higher than the first peak wavelength;
a plurality of third light emitters configured to emit a third light having a third peak wavelength that is shorter than the first peak wavelength; and
a controller configured to control the plurality of first light emitters, the plurality of second light emitters, and the plurality of third light emitters such that a first light pattern and a second light pattern are generated,
wherein each of the plurality of first light emitters, the plurality of second light emitters, and the plurality of third light emitters comprises:
a first semiconductor layer;
a second semiconductor layer, and
an active layer, the active layer being disposed on the first semiconductor layer to emit a light having a specific wavelength due to a band gap difference in an energy band depending on a material used to form the active layer,

wherein the first light pattern comprises a first light spectrum and the second light pattern comprises a second light spectrum including at least one more peak wavelength than the first light spectrum, and
wherein a composition ratio of the plurality of first light emitters and the plurality of second light emitters differ.
