  Vertical GaN is a power semiconductor technology where current flows vertically through a GaN-on-GaN structure rather than laterally across the surface, enabling much higher breakdown voltages, current densities, and switching speeds in a compact device. By using bulk GaN layers on native GaN substrates, it reduces defects, improves thermal handling and avalanche robustness, and [...]

  Red-green-blue-amber-lime (RGBAL) light engines are evolving toward higher spectral quality, more channels, and smarter control, with a strong push from pro‑stage, film, and architectural applications. From RGBAL to multi-spectral Manufacturers are extending beyond RGBAL into 6–8 color engines (e.g., adding royal blue, deep red, indigo) to widen gamut and fix “gappy” spectra from older [...]

  UV LEDs are increasing being used in manufacturing to replace mercury lamps for applications like UV curing and lithography. UV-A/B LED curing is production‑ready in many industrial segments, while deep UV‑C LED curing is still emerging and application‑specific rather than a drop‑in replacement for mercury sources, across the board. For UV‑A/UV‑B curing (inks, coatings, [...]

  Researchers have developed a new way to make ultra-narrow band, near‑infrared LEDs by “electrically powering” materials that normally do not conduct, using attached organic molecules that act as molecular antennas. The work opens a path to highly precise light sources for deep‑tissue medical imaging, optical communication, and chemical or biological sensing. Core scientific breakthrough [...]

  Peacock feathers contain reflective microstructures that can amplify light into laser beams when dyed and energized, representing the first example of a natural laser cavity in the animal kingdom. Discovery of Laser Potential Scientists at Florida Polytechnic University explored whether the intricate ordered structures responsible for the feathers’ well-known structural color—vivid blues and greens [...]

  Laser headlights technology and development are being abandoned by carmakers due to US automotive regulations and rapid advancements in LED technology, making lasers unnecessary and less practical for automakers. Regulatory Roadblocks The United States Federal Motor Vehicle Safety Standard (FMVSS) rule 108 has imposed strict limits on headlight brightness (150,000 candela) and beam range [...]

  In a recent research paper titled “A New Way to Understand the Color Rendition Performance of Multi-Primary Light Sources” published in Leukos, the researchers introduce a novel approach to evaluating and characterizing the color rendition performance of tunable, multi-primary light sources—a class of modern illumination technologies with significant applications in architecture, entertainment, and display [...]

  Chinese manufacturer, EXC Technology, claims to have surpassed the 250 lumens per watt (lm/W) efficiency barrier—a significant milestone in the pursuit of more energy-efficient outdoor lighting. The company, based in Shenzhen, unveiled its MYS4C/MLS6C module, reporting a luminous efficacy of 250.5 lm/W. EXC attributes this high efficiency to a combination of advanced optical design, [...]

Seaborough B.V., a Netherlands-based leader in nano-engineered downconverters, and Luminus Devices have announced a partnership to bring the world’s first LEDs with nano-engineered Eu3+-based phosphor to market, on a commercial scale. This new partnership gives Luminus Devices early access to Seaborough’s unique phosphor technology, EuroLED, which Seaborough claims to be a high quality, more sustainable, [...]
