LED ILLUMINATING APPARATUS

摘要

The LED lighting device in this invention comprises a light source, a first face sheet, and a reflection sheet. The light source comprises a plurality of LED chips which are configured to emit lights having wavelengths which are different from each other. The first face sheet has a rear surface. The rear surface is defined as a diffusing and reflecting surface which is being configured to diffuse and reflect the lights which are emitted from the LED chips. The first face sheet is provided with a plurality of apertures. The reflection sheet has a second reflecting surface . The second reflecting surface is configured to reflect the light which is reflected from the diffusing and reflecting surface of the first face sheet toward the first face sheet. Each the aperture is shaped to pass the light which is reflected from the second reflecting surface. Each the aperture is configured to prevent the light which is directly emitted by the light from being passed through the aperture without being subjected to any reflection.
