Govee announced new ceiling lighting products at CES 2026, including the Sky Ceiling Light that mimics daylight for windowless spaces and the Ceiling Light Ultra, a highly customizable LED canvas with AI-driven lighting effects, expanding their innovative smart lighting lineup.
LG has announced its first flagship Micro RGB evo TV featuring micro-RGB LEDs for exceptional color accuracy, powered by an AI-enhanced chipset, with support for multiple color gamuts and over a thousand dimming zones, available in three sizes ahead of CES 2026.
LG announced a new Micro RGB Evo TV to be unveiled at CES 2026, available in 75, 86, and 100-inch sizes, offering high contrast, wide color gamut, and brightness advantages over OLEDs, with prices likely higher than typical consumer TVs but potentially more affordable than Samsung's and Hisense's ultra-large models.
Samsung has introduced the world's first Micro RGB display technology in a 115-inch TV, featuring sub-100 micrometer RGB LEDs that offer superior contrast, color accuracy, and energy efficiency, with AI-driven optimizations and enhanced security features, initially launched in South Korea and set to expand globally.
Nanlite has introduced the Pico, a compact, pocket-sized RGBW LED light weighing just 4.6 ounces, designed for content creators and mobile filmmakers. It features a powerful Nebula C4 engine with full RGBW output, a wide CCT range, high color fidelity, and versatile mounting options. The Pico offers up to 6.5 hours of battery life, built-in effects, and smart controls via Bluetooth app, all at an affordable price of $35.
Indicator lights on household electronics, often brighter and more numerous than before, can disrupt sleep by interfering with the natural darkness needed for slumber. While some manufacturers argue that these lights serve practical and aesthetic purposes, many people find them to be a nuisance. Solutions range from using blackout stickers to covering the lights with tape or clothing. LED lights, particularly blue ones, are commonly used for indicators due to their energy efficiency and long lifespan, but their disruptive effect on sleep has led to debate over their necessity.
Nanoleaf has introduced the Skylight, a set of smart ceiling light panels that mimic a skylight and offer customizable lighting options. The panels can be expanded beyond the original fixture without additional wiring, and they integrate with smart home systems and offer various color schemes and motion effects. While installation may be more complicated than traditional fixtures, the product has received positive feedback, although connectivity issues have been reported. Despite this, Nanoleaf is known for proactive updates and potential future improvements.
When shopping for a new TV, it's important to understand the different types available. LCD and LED TVs are based on LCD technology, with LEDs used to enhance picture quality. OLED TVs, on the other hand, use Organic Light Emitting Diodes to create images at the pixel level, resulting in near-perfect blacks. LED TVs with local dimming offer superior contrast, while OLED TVs may have lower brightness and potential burn-in issues. Understanding these distinctions can help buyers make an informed decision when choosing a new TV.
Researchers from Cornell University and Ben-Gurion University of the Negev have developed a method of stealing encrypted keys by analysing the brightness and colour of a device's power light. The team showed the effectiveness of the method by hijacking an internet-connected security camera and capturing footage of the power LED of a smart card reader 16 metres away. After processing and analysing the footage, the team was able to recover the 256-bit key. The method is a form of side-channel attack, which exploits information gleaned from a fundamental or physical characteristic of a system, inadvertently leaking information to hackers.
The increased use of light-emitting diodes (LED) and other forms of lighting are now brightening the night sky at a dramatic rate, scientists have found. In 2016, astronomers reported that the Milky Way was no longer visible to a third of humanity and light pollution has worsened considerably since then. At its current rate most of the major constellations will be indecipherable in 20 years, it is estimated. Light pollution is having serious ecological consequences, including confusing sea turtles and migrating birds, and killing insects. It is also having health implications, as the bluish emissions of LEDs are almost entirely lacking any red or near infrared light, which stimulates mechanisms that break down high levels of sugar in the blood or boost melatonin production.
The assumption that the internal quantum efficiency (IQE) of blue light-emitting diodes (LEDs) is always 100% is wrong, according to a new study from University of Illinois Urbana-Champaign Electrical and Computer Engineering researchers. The IQE of an LED can be as low as 27.5%. To meet the efficiency standards laid out by the DOE, it will be increasingly important to properly quantify the efficiency of LEDs.
Researchers in Singapore have developed the world's smallest LED that enables the conversion of existing mobile phone cameras into high-resolution microscopes. The LED was used to build the world's smallest holographic microscope, paving the way for existing cameras in everyday devices such as mobile phones to be converted into microscopes via only modifications to the silicon chip and software. The researchers also developed a revolutionary neural networking algorithm that is able to reconstruct objects measured by the holographic microscope, thus enabling enhanced examination of microscopic objects such as cells and bacteria without the need for bulky conventional microscopes or additional optics.
Researchers at Sandia National Laboratories have demonstrated the ability to dynamically steer light pulses from incoherent light sources using artificially structured materials called metasurfaces, made from tiny building blocks of semiconductors called meta-atoms that can be designed to reflect light very efficiently. This breakthrough could allow low-power, relatively inexpensive sources like LEDs or flashlight bulbs to replace more powerful laser beams in new technologies such as holograms, remote sensing, self-driving cars, and high-speed communication.
