LED MODULE AND LIGHTING APPARATUS - A simplified explanation of the abstract
This abstract first appeared for US patent application 18158207 titled 'LED MODULE AND LIGHTING APPARATUS
Simplified Explanation
The abstract describes a patent application for a LED module that emits white light. The module consists of a blue LED that emits light in the range of 420 nm to 465 nm, and a near-infrared wavelength conversion material that is excited by the blue light to emit additional light in the range of 740 nm to 900 nm, with a narrow bandwidth of 120 nm or less.
- The LED module emits white light by combining blue light and near-infrared light.
- The blue LED emits light in the range of 420 nm to 465 nm.
- The near-infrared wavelength conversion material is excited by the blue light and emits light in the range of 740 nm to 900 nm.
- The emitted near-infrared light has a narrow bandwidth of 120 nm or less.
- The near-infrared wavelength conversion material used is Ca(Al,Ga)O:xCr, where 0≤x≤1 and 0≤y≤6.
Potential Applications
- Lighting applications where white light is required, such as indoor and outdoor lighting.
- Display applications, such as backlighting for LCD screens.
- Automotive lighting, including headlights and taillights.
- Medical applications, such as phototherapy and diagnostic imaging.
Problems Solved
- Provides a solution for generating white light using a combination of blue and near-infrared light.
- Offers a narrow bandwidth of near-infrared light, improving the quality and efficiency of the emitted white light.
Benefits
- Energy-efficient lighting solution with improved color rendering.
- Versatile application in various industries, including lighting, displays, automotive, and healthcare.
- Enhanced performance and durability compared to traditional lighting technologies.
Original Abstract Submitted
A light emitting diode (LED) module that is configured to emit white light is provided. The LED module includes: a blue light emitting diode configured to emit blue light having a first peak wavelength of 420 nm to 465 nm; and a near-infrared wavelength conversion material that is configured to be excited by the blue light to emit additional light having a peak wavelength in a range of 740 nm to 900 nm, and further having a full width at half maximum (FWHM) of 120 nm or less. The near-infrared wavelength conversion material includes Ca(Al,Ga)O:xCr (0≤x≤1, 0≤y≤6).
