Exemplarily, assuming that the lighting device 100 includes 29 light emitting modules, wherein the 29 light emitting modules may be divided into 6 light emitting groups, a first light emitting group includes 4 light emitting modules arranged in a two-dimensional matrix of 2 × 2, a second light emitting group includes 4 light emitting modules arranged in a two-dimensional matrix of 2 × 2, a third light emitting group includes 4 light emitting modules arranged in a two-dimensional matrix of 2 × 2, a fourth light emitting group includes 4 light emitting modules arranged in a two-dimensional matrix of 2 × 2, a fifth light emitting group includes 4 light emitting modules arranged in a two-dimensional matrix of 2 × 2, and a sixth light emitting group includes 9 light emitting modules arranged in a two-dimensional matrix of 3 × 3.
Thus, by providing a light emitting group including a plurality of light emitting modules arranged in a two-dimensional matrix form, the number of times of replacement of the light barrier of the illumination device can be reduced, so that the usability of the illumination device can be improved. In addition, the adaptability of the light emitting set and the light barrier can be enhanced.

Therefore, the light guide component is arranged, so that the light emitted by the light emitting module can be adjusted to be better irradiated to the outside of the lighting device, and the position configuration of the light emitting module and the light barrier is more flexible.
In one implementation, the control unit 150 adjusts the chromaticity and/or the color temperature of the lighted light emitting module 130 according to an instruction from the external device 120.
For example, the control module 150 may store information including a smart illumination curve, and instruct the illuminated light emitting module 130 to perform an illumination display according to the smart illumination curve through a command transmitted to the illuminated light emitting module 130.
