ILLUMINATOR AND PROJECTOR - A simplified explanation of the abstract
This abstract first appeared for US patent application 18605990 titled 'ILLUMINATOR AND PROJECTOR
The abstract describes an illuminator that combines light from two different sources, diffuses it, collects it, parallelizes it, homogenizes it, vibrates it, and superimposes the light fluxes.
- First light source outputs light in a first wavelength band
- Second light source outputs light in a second wavelength band
- Light combining member combines the two lights
- Diffuser diffuses the combined light
- Light collector collects and directs the light towards the diffuser
- Collimator parallelizes the light outputted from the diffuser
- Light homogenizer integrates two lens array surfaces to homogenize the light
- Vibration generator vibrates the light homogenizer
- Superimposing lens superimposes the light fluxes
Potential Applications: - Medical imaging - Microscopy - Photography lighting - Industrial inspection - Display technology
Problems Solved: - Achieving uniform lighting - Enhancing image quality - Improving light efficiency - Reducing glare and shadows - Enhancing color accuracy
Benefits: - Improved lighting uniformity - Enhanced image quality - Increased light efficiency - Reduced glare and shadows - Enhanced color reproduction
Commercial Applications: Title: Advanced Illumination Technology for Various Industries This technology can be used in medical imaging devices, microscopy equipment, photography studios, industrial inspection tools, and display technology, offering improved lighting quality and efficiency for a wide range of commercial applications.
Questions about Illuminator Technology: 1. How does the vibration generator contribute to the performance of the illuminator? 2. What are the advantages of using a superimposing lens in this illuminator system?
Original Abstract Submitted
An illuminator includes a first light source that outputs first light having a first wavelength band, a second light source that outputs second light having a second wavelength band different from the first wavelength band, a light combining member that combines the first light and the second light with each other and outputs combined light, a diffuser that diffuses the combined light incident thereon, a light collector that collects the combined light and directs collected combined light toward the diffuser, a collimator that parallelizes the combined light outputted from the diffuser, a light homogenizer having a first lens array surface on which the combined light outputted from the collimator is incident and a second lens array surface integrated with the first lens array surface, a vibration generator that vibrates the light homogenizer, and a superimposing lens that superimposes light fluxes outputted from the light homogenizer on one another.
