Claim 0:
1. A light module comprising:
a first light emitter configured to emit a first light having a first peak wavelength in a visible range;
a second light emitter configured to emit a second light having a waveform having a second peak wavelength higher than the first peak wavelength;
a third light emitter 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 first light emitter, the second light emitter, and the third light emitter such that a first light pattern and a second light pattern are generated,
wherein each of the first light emitter, the second light emitter, and the third light emitter 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 the controller controls the third light emitter to turn off when the second light emitter turns on.
