Light-emitting apparatus capable of adjusting a color of a projected light thereof

A light-emitting apparatus includes a light source to emit light, a photonic crystal to pass light of different wavelengths based on the light from the light source, and a projector to project the light passing through the photonic crystal. The photonic crystal may be electrically or mechanically co...

More Information
Summary:A light-emitting apparatus includes a light source to emit light, a photonic crystal to pass light of different wavelengths based on the light from the light source, and a projector to project the light passing through the photonic crystal. The photonic crystal may be electrically or mechanically controlled to pass the different wavelengths of light.
