At-home use of red light therapy masks requires a purposeful, consistent approach. These are the steps for the best results.

Littelfuse, Inc. announced the launch of the TPSMB Asymmetrical Series TVS Diodes (TPSMB2412CA, TPSMB2616CA, TPSMB2818CA, TPSMB3018CA). These first-to-market devices are specifically designed for 12V ...

Discover how to build a simple device that converts light into electricity using LEDs and diodes. This step-by-step guide demonstrates assembling an LED-diode cluster, connecting it to a capacitor for ...

The LED, or light-emitting diode, is very unlikely to fail, and if it does, it goes out slowly over the years. Instead, it's the other electrical bits in LED bulbs that fail and cut off the bulb's ...

WASHINGTON — The Board of Directors of Optica, Advancing Optics and Photonics Worldwide, recently elected 121 members from 23 countries to the Society’s 2026 Fellow Class. Optica Fellows are selected ...

Engineers in Switzerland have built light-emitting diodes so small that hundreds could line up across the width of a single human cell, shrinking a core component of modern electronics to a scale that ...

Now's the time to get in on some great deals on RGB home lighting in preparation for the holidays. For Black Friday, Amazon is offering up to 40% off Govee's popular lineup of Outdoor Lights Pro ...

Our expert staff answers frequently asked questions in their areas of expertise and defines common terms so you can be a smarter shopper. Read more here. Red LED face masks have dominated the ...

The LED Volume is derived from the concept of Image-Based Lighting (IBL) invented by Paul Debevec in 1998, which refers to mapping an HDR image onto a photosphere enveloped around a subject to serve ...

Abstract: This study proposes a novel light-emitting diode (LED) driver circuit that stabilizes the lighting output without a photodiode. The LED driver circuit is composed of a self-alignment circuit ...

Abstract: This paper proposes a novel single-stage ac-to-dc light-emitting-diode (LED) driver circuit. A buck-boost power factor (PF) corrector is integrated with a flyback converter. A recycling path ...
