The smart LED device 300D of FIG. 13 may be implemented to include an LED driver 310D, an RGB LED array 321E, an IR LED array 322E, a UV LED array 323E, and a VCSEL array 324E.

In this case, the RGB LED array 321E, the IR LED array 322E, the UV LED array 323E, and the VCSEL array 324E may be variously spaced apart so as not to interfere with each other. For example, the RGB LED array 321E, the IR LED array 322E, the UV LED array 323E, and the VCSEL array 324E are spaced apart in a cylindrical shape or a grid pattern so that the emitted light does not interfere with each other. I can.

Although the present application has been described with reference to the exemplary embodiment illustrated in the drawings, this is only exemplary, and those of ordinary skill in the art will appreciate that various modifications and equivalent other exemplary embodiments are possible therefrom. Therefore, the true technical protection scope of the present application should be determined by the technical idea of the attached registration claims.
