Liquid cooling is taking off as a critical thermal management technology for the booming AI data center industry. Liquid cooling protects AI servers from damaging heat, and also reduces energy consumption for cooling AI data centers. Can liquid cooling help with LED luminaire thermal management? In the early days of LED technology, LEDs were inefficient [...]

Mojo Vision, a California-based company, has been developing smart augmented reality (AR) contact lenses since 2015. In June 2022, they successfully demonstrated a functioning prototype of their “Mojo Lens,” marking a significant milestone in the development of AR contact lens technology. The Mojo Lens features an impressive array of miniaturized components: A Micro LED display [...]

In commercial and industrial LED lighting, drivers historically were isolated using transformers to step-down voltage, however there is increasing use of non-isolated drivers. Understanding Isolated Drivers An isolated driver is an electrical device that employs a transformer to step down high voltage to a lower one, which is then rectified into DC output. The term [...]

I’ve previously written about predictions for color-mixed white LED’s (CM-LEDs) to eventually surpass phosphor-converted LEDs (PC-LEDs) in both efficacy and spectral tuning capabilities. More on this is available here. But what is it going to take to bring about all of the advantages of CM-LEDs for general lighting? The primary technical barrier is the very [...]

  For a couple years, OLEDWorks has been developing and supplying cutting edge OLED tail lights to Audi. These tail lights go beyond indicating breaking. They also provide symbols alerting drivers behind the tail lights of accidents, construction, other road hazards, and personalization of the tail lights, by the owner. More information on the latest [...]

By: Kevin Green, Global Commercial Director, BrightView Technologies There is a fundamental demand uniting lighting objectives across outdoor and indoor architectural environments. Whether it’s spotlighting specific design features or illuminating a room with unique light patterns, precision is the name of the game in bringing innovative concepts to life. As architectural demands have grown more [...]

Utility programs in four Northeast states have evaluated LED linear ambient market share. The utility consulting firm, DNV, performed all four rebate program evaluation reports for Rhode Island, Massachusetts, Connecticut, and New Jersey. Projected LED linear ambient market share for 2023 ranges from 83% to 94%. Market shares this high may eventually make it difficult [...]

The December issue of designing lighting (dl) magazine has an interesting story about recent research into running infrared (IR) LEDs in reverse polarity to create active cooling. One caveat for this approach to work is that the object to be cooled has to be incredibly close to the IR LED — less than 1 wavelength’s [...]

Quantum-dot LEDs (QD-LEDs) are based on quantum dots (QDs), semiconductor particles just a few nanometers in size. Because of their extremely small size, their behaviour is governed by quantum mechanics. By ‘exciting’ quantum dots with electricity or driving radiation, they can be induced to emit light, the color of which is determined by the size [...]
