WAVELENGTH CONVERSION DEVICE, PHOSPHOR WHEEL, LIGHT SOURCE DEVICE, PROJECTION DISPLAY APPARATUS, AND METHOD FOR MANUFACTURING WAVELENGTH CONVERSION DEVICE - A simplified explanation of the abstract
This abstract first appeared for US patent application 18242639 titled 'WAVELENGTH CONVERSION DEVICE, PHOSPHOR WHEEL, LIGHT SOURCE DEVICE, PROJECTION DISPLAY APPARATUS, AND METHOD FOR MANUFACTURING WAVELENGTH CONVERSION DEVICE
Simplified Explanation
The patent application describes a wavelength conversion device that can generate light with different wavelengths from an incident light source.
- The device includes a wavelength conversion element with multiple wavelength converters arranged in a specific direction.
- Each wavelength converter consists of two phosphor layers that convert the incident light into different fluorescent lights.
- The first phosphor layer converts the incident light into the second light with a different wavelength, while the second phosphor layer converts it into the third light with another different wavelength.
- The first and second phosphor layers are arranged adjacent to each other in an alternating pattern along the first direction.
Potential applications of this technology:
- Lighting systems: The wavelength conversion device can be used in LED lighting systems to generate light with different colors or color temperatures.
- Display technology: It can be applied in displays to enhance color accuracy and provide a wider color gamut.
- Medical imaging: The device can be utilized in medical imaging devices to improve image quality and enhance contrast.
Problems solved by this technology:
- Limited color options: The wavelength conversion device allows for the generation of light with different wavelengths, providing a broader range of color options.
- Inefficient light conversion: The use of multiple wavelength converters increases the efficiency of converting incident light into desired wavelengths.
- Compact design: The arrangement of the wavelength converters in a specific direction allows for a compact and space-saving design.
Benefits of this technology:
- Versatile lighting options: The device enables the creation of lighting systems with adjustable colors and color temperatures.
- Improved image quality: In medical imaging or display applications, the technology enhances color accuracy and contrast, resulting in improved image quality.
- Energy efficiency: The efficient light conversion process reduces energy consumption and increases overall energy efficiency.
Original Abstract Submitted
The wavelength conversion device includes a wavelength conversion element that generates, from incident first light, second light having a wavelength different from a wavelength of the first light and third light having a wavelength different from the wavelength of the first light and the wavelength of the second light. The wavelength conversion element includes a plurality of wavelength converters arranged adjacent to each other in a first direction. Each of the plurality of wavelength converters includes a first phosphor layer that converts the first light into fluorescent light that is the second light, and a second phosphor layer that converts the first light into fluorescent light that is the third light. The first phosphor layer and the second phosphor layer are arranged adjacent to each other to cause the plurality of first phosphor layers and the plurality of second phosphor layers to be alternately arranged in the first direction.
