Latest Patents
One of his latest patents is titled "Etendue-conserving illumination-optics for backlights and frontlights." This invention provides luminance-preserving non-imaging backlights that utilize a luminous source emitting light. The design includes an input port that receives the light, an injector, and a beam-expanding ejector. The injector is defined by a surface of revolution, ensuring that the x-y angular width of the source image remains inversely proportional to its luminance. The beam-expanding ejector features a planar waveguide that is optically coupled to the output port of the injector, enhancing the overall efficiency of the lighting system.
Another notable patent is the "Neon-tube substitute using light-emitting diodes." This invention efficiently utilizes high-brightness unlensed LEDs to replicate the homogeneous appearance of a neon tube. The transparent tube is designed with an annular cross-section, allowing for cost-effective manufacturing. The LEDs are strategically mounted on a circuit board, which can be positioned inside or outside the tube. The design ensures that the light is reflected laterally, creating a homogenous glow that mimics traditional neon lighting.
