Referring to
As above, compared with the prior art, the present invention has, at least advantages as follows.
1. A manner of providing the photo-luminescence material is adopted, and the at least two independently-distinguished light-emitting regions and the at least two independently-controlled circuit structures are cooperatively adopted, so light having two wavelengths may be emitted at least.
2. By independently controlling the at least two circuit structures, light intensities of the light having two wavelengths can be further slightly adjusted to adjust color temperatures so as to make wavelengths consistent.
3. The circuit structures are provided on the single wafer substrate, processing and manufacturing can be completed at the same time, miniaturization can be achieved, manufacturing costs can be reduced, and demands in use can be met.
