Light apparatus capable of emitting light of multiple wavelengths using nanometer fluorescent material, light device and manufacturing method thereof

摘要

A light apparatus is capable of emitting light of multiple wavelengths using a nanometer fluorescent material. The light apparatus comprises an initial light source that emits initial color light. The initial light source is covered with a transparent film member; and the inside or the surface of the film member, or the initial light source, is coated with at least one nanometer fluorescent material. The nanometer fluorescent material absorbs the initial color light and gets excited, and in the excitement it emits fluorescent light which is different from the initial color light. The initial color light and the fluorescent light combine to form light of multiple wavelengths, and the light of multiple wavelengths is emitted by the light apparatus. Besides, a combination of nanometer fluorescent materials of various particle sizes enables the emission of multiple-wavelength light of various dominant wavelengths.
