  Alloy LED’s Radialux 5.5 COB RGBTW Tape Light represents an innovative convergence of RGBTW with COB tape. This five-channel tape light integrates dynamic RGB color-changing with tunable white light ranging from 2700K to 6500K, all within a non-pixilated Chip-on-Board (COB) construction. The result is a smooth, uninterrupted line of illumination for better looking architectural [...]

  While primarily utilized in entertainment lighting, 5-channel color mixing is beginning to be adopted in high performance architectural fixtures, as well. This includes two approaches: red-green-blue-amber-lime (RGBAL) and red-green-blue-indigo-lime (RGBIL). Here is a comparison between the two 5-channel color mixing approaches. The differences between RGBAL and RGBIL LEDs primarily involve color rendering, spectral output, and specialized application needs. [...]

  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 [...]
