LIGHT-EMITTING DEVICE AND ELECTRONIC APPARATUS - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240347677 titled 'LIGHT-EMITTING DEVICE AND ELECTRONIC APPARATUS
Simplified Explanation: The patent application describes a light-emitting device that includes a solid-state light-emitting element, a wavelength converter with a phosphor containing a fluorescent ion, and an optical member that reflects primary light while transmitting fluorescence emitted by the fluorescent ion.
- The device has a solid-state light-emitting element emitting primary light.
- A wavelength converter with a phosphor absorbs the primary light through a forbidden transition-type electronic energy transition.
- An optical member reflects primary light and transmits fluorescence emitted by the fluorescent ion.
- The solid-state light-emitting element is on one surface of the wavelength converter, and the optical member is on the other surface.
- Fluorescence emitted by the fluorescent ion passes through the optical member and is output from the device.
Key Features and Innovation:
- Integration of a solid-state light-emitting element, a wavelength converter, and an optical member in a light-emitting device.
- Use of a phosphor with a fluorescent ion for wavelength conversion.
- Efficient reflection of primary light and transmission of fluorescence for enhanced light output.
Potential Applications:
- Lighting applications in residential, commercial, and industrial settings.
- Display technologies for televisions, monitors, and signage.
- Automotive lighting for headlights, taillights, and interior lighting.
Problems Solved:
- Enhancing light output efficiency.
- Improving color rendering and brightness.
- Providing a compact and integrated light-emitting device.
Benefits:
- Energy-efficient lighting solutions.
- Enhanced color quality and brightness.
- Compact and versatile design for various applications.
