Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
What is claimed is: 1. A light-emitting apparatus comprising: a light source configured to emit light; a photonic crystal configured to pass light of different wavelengths based on the light emitted from the light source; and a projector configured to project the light which passes through the photonic crystal, the photonic crystal configured to be electrically controlled to selectively pass the different wavelengths of light. 2. The light-emitting appara…
