Innovation Summary:
This invention presents a high-efficiency light source that integrates a solid-state emitter—such as an LED or laser diode—with a down-conversion material and an optical feedback system. The design captures both forward and backward emitted light from the down-conversion layer and redirects it to enhance overall luminous output. This configuration significantly improves light extraction and spectral control, resulting in a more efficient and tunable lighting system. The technology is ideal for applications requiring high brightness, energy efficiency, and compact form factors.
Challenges / Opportunities:
Conventional solid-state lighting systems often lose a portion of emitted light due to backward scattering and limited spectral conversion. This invention addresses those inefficiencies by incorporating an optical element that recycles backward-emitted light, increasing usable output. It opens opportunities in advanced lighting, display technologies, and energy-saving illumination systems where performance and efficiency are paramount.
Key Benefits / Advantages:
✔ Increased luminous efficiency through light recycling
✔ Tunable emission spectrum using down-conversion materials
✔ Compact, thermally stable design
✔ Compatible with a range of solid-state emitters
Applications:
• Energy-efficient lighting systems
• High-performance displays and projectors
