COLOR FILTERING DBR FOR MICRO-LEDS - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240243225 titled 'COLOR FILTERING DBR FOR MICRO-LEDS
The abstract describes a device that includes a light emitting diode (LED) that emits light with a peak wavelength, a lower wavelength band, and a higher wavelength band. The device also includes a reflector positioned in one direction from the LED and a distributed Bragg reflector (DBR) positioned in the opposite direction from the LED, with a lower reflectance than the reflector, and configured to block light within a stopband that overlaps with a portion of the lower or higher wavelength bands but not the peak wavelength.
- LED emits light with peak, lower, and higher wavelength bands
- Reflector and DBR positioned in opposite directions from the LED
- DBR has lower reflectance than the reflector
- DBR blocks light within a stopband overlapping with lower or higher wavelength bands but not the peak wavelength
- DBR propagates filtered light in the opposite direction from the LED
Potential Applications: - Lighting applications - Optical communication systems - Display technologies
Problems Solved: - Filtering specific wavelengths of light - Directing light in a controlled manner
Benefits: - Enhanced light control - Improved efficiency in light emission - Potential for new lighting designs
Commercial Applications: Title: "Advanced LED Lighting Technology for Enhanced Control" This technology could be used in various commercial applications such as: - Smart lighting systems for homes and offices - Automotive lighting systems - Entertainment lighting for theaters and events
Questions about the technology: 1. How does the distributed Bragg reflector enhance the performance of the LED device?
The DBR blocks specific wavelengths of light, allowing for more precise control over the emitted light.
2. What are the potential cost implications of implementing this technology in commercial products?
The cost may vary depending on the scale of production and the specific requirements of the application.
Original Abstract Submitted
a device includes a light emitting diode (led) configured to emit light characterized by a peak wavelength, a lower wavelength band extending across lower wavelengths than the peak wavelength, and a higher wavelength band extending across higher wavelengths than the peak wavelength. the device also includes a reflector positioned in a first direction from the led. the device also includes a distributed bragg reflector (dbr) having a lower reflectance than the reflector, positioned in a second direction from the led opposite the first direction, and configured to block light within a stopband overlapping a portion of the lower wavelength band or a portion of the higher wavelength band but not overlapping the peak wavelength, such that the dbr propagates filtered light in the second direction.
