Maka on Boost-Buck LED Driver Topology for Low Input and Output Ripple for Low EMI by Linear Technology

Many automotive LED driver circuits require constant-current DC/DC converter topologies that can both step-up and step-down the input-to-output voltage. Out of the commonly used step-up and step-down topologies, those that produce low EMI are the most desirable. Keith Szolusha, applications engineering section leader with Linear Technology, proposes a new boost-buck (boost-then-buck-mode) floating output LED driver to satisfy these requirements.

Flicker-Free Control of Individual LEDs in Matrix Headlights

Flicker-Free Control of Individual LEDs in Matrix Headlights

LEDs combine design flexibility with practical, robust circuitry, enabling automotive designers to produce striking headlight designs matched by exceptionally long life and performance. Keith Szolusha, Sr. Design Leader for LED driver products at Linear Technology, and now part of Analog Devices explains how automobile designers are increasingly incorporating LEDs in lighting because they can be arranged in distinctive eye-catching designs - helping distinguish new models from old, or high end from economy.

“UV Power” Research Project Is Working on LED-Replacements for Conventional UV Light Sources

“UV Power” Research Project Is Working on LED-Replacements for Conventional UV Light Sources

Since February 2017, a total of five research institutes and companies have been working on “UV Power”, a collaborative project funded by the German Federal Ministry of Education and Research (BMBF). The partners have made it their goal to provide high-power UV LEDs to cover a wide variety of applications. These LEDs will eventually replace conventional UV light sources, which often contain toxic mercury, in areas such as production, disinfection, the environment, life sciences and medicine. UV LEDs are also likely to open up new areas of application.

New LRC Study Tests the Impact of Circadian Light on Alertness in Office Workers

New LRC Study Tests the Impact of Circadian Light on Alertness in Office Workers

In 2017 the Lighting Research Center (LRC) at Rensselaer Polytechnic Institute published a groundbreaking study showing that office workers who receive a robust dose of circadian-effective light experience better sleep, and lower levels of depression and stress, than those who spend their days in dim or low light levels. The team of LRC researchers, led by Dr. Mariana Figueiro and sponsored by the U.S. General Services Administration, measured existing light levels for 109 participants at five federal office buildings designed to maximize daylight availability indoors. The research team found that even in open offices with many, large windows, office workers were not receiving enough light to stimulate their circadian system during the day, due to factors such as season, cloud cover, desk orientation, and window shade position.
