ILLUMINATION DEVICE AND PROJECTOR - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240329508 titled 'ILLUMINATION DEVICE AND PROJECTOR
The abstract describes an illumination device that combines light from two sources and reflects it diffusely using a rotating diffusion device.
- First light source emits first light
- Second light source emits second light
- Light combining member merges the two lights to emit illumination light
- Rotary diffusion device with diffusing surface reflects the illumination light
- Driver rotates the substrate on a rotational axis
- Condenser condenses the light towards the diffusion device
- Collimator collimates the diffusion light
Potential Applications: - Architectural lighting - Automotive lighting - Stage lighting - Display lighting
Problems Solved: - Efficient light diffusion - Enhanced illumination coverage - Dynamic light control
Benefits: - Improved light quality - Energy efficiency - Versatile lighting options
Commercial Applications: Title: Innovative Illumination Device for Diverse Lighting Needs This technology can be used in various commercial settings such as: - Theatres - Restaurants - Retail stores - Offices
Questions about the technology: 1. How does the rotating diffusion device improve light diffusion?
- The rotating diffusion device ensures even distribution of light by reflecting it diffusely across a surface.
2. What are the advantages of using multiple light sources in this illumination device?
- Using multiple light sources allows for a wider range of lighting options and enhances the overall quality of illumination.
Original Abstract Submitted
an illumination device includes a first light source configured to emit first light, a second light source configured to emit second light, a light combining member configured to combine the first light and the second light with each other to emit illumination light, a rotary diffusion device having a substrate including a diffusing surface configured to diffusely reflect the illumination light, and a driver configured to rotate the substrate centering on a rotational axis, a condenser disposed between the light combining member and the rotary diffusion device, and configured to condense the illumination light toward the rotary diffusion device, and a collimator configured to collimate diffusion light of the illumination light. the diffusing surface of the substrate includes a first area where a first uneven structure is disposed, and a second area where a second uneven structure different from the first uneven structure is disposed.
