Claim 15:
16. A lighting device for plant cultivation, comprising:
a light module comprising a substrate and a light source unit, the light source unit comprising:
a first light source unit comprising two or more first light sources;
a second light source unit comprising two or more second light sources; and
a third light source unit comprising two or more third light sources; and
wherein the light sources of each light source unit include at least one light source that emits a first type of light and at least one light source that emits a second type of light, the first and second types of light having peak wavelengths in different wavelength bands;

a controller controlling operation of the first light source unit, the second light source unit, the third light source unit, individually or in combination;
an input unit through which a signal for controlling the light source unit is input;
a storage unit storing data with respect to operation of the light source unit in response to the signal input through the input unit; and
wherein the controller controls operation of the light source unit by obtaining the data with respect to operation of the light source unit from the storage unit in response to the signal input through the input unit, wherein the data with respect to operation of the light source unit for at least one signal causes the controller to operate the light source unit to irradiate the target plant with the first type of light to reduce damage in the target plant due to irradiation with the second type of light.
