There is much interest in LED-based lighting due to the availability of high-power, high-efficiency white—and other-color—LEDs (Reference 1). Because an LED is a current-controlled device, typical ...

Light-emitting diodes (LEDs) used in lighting products and systems have become a global revolution, leading to significant changes to how designers build lighting into their automotive lighting, ...

Infrastructure projects like the Tokyo Gate Bridge are now turning to LED lighting because of its economical and environmental advantages. But these devices still need the right current-limiting ...

It seems deceptively simple to establish galvanic isolation with the help of optocouplers between circuits that operate at different ground potentials. Optocouplers draw power from the isolated ...

Automotive lighting growth is driven by natural LED cost erosion, increasing the LED penetration rate. Standardization of LED modules and their optimization are key factors behind decreasing costs.
