[Peter] needed to drive a high power LED for his microscope. Rather than pick up a commercial LED driver, he built a simple constant current LED driver and fan control. We’ve featured [Peter’s] ...

Santa Clara, Calif. — National Semiconductor Corp. has designed a Boomer light emitting diode (LED) driver that provides audio synchronization without real-time software processing. The LM4970 LED ...

A white LED delivers a wide color spectrum and better visibility than do monochromatic LEDs. However, a white LED presents a higher forward-voltage drop than do its colorful counterparts and thus ...

Tagging wildlife is never straightforward in the best of times, but it becomes a great deal more complicated when you’re trying to track flying insects. Instead of trying to use a sensor package, ...

Supertex, Inc. has introduced the HV9910, which it describes as the industry's first universal, high brightness (HB) LED driver IC. The HV9910 is a highly flexible and simple LED driver IC that ...

ZHUHAI, GUANGDONG, CHINA, January 21, 2026 /EINPresswire.com/ -- As intelligent lighting rapidly becomes the core of ...

This idea describes a white- LED (WLED) driver circuit controlled by a simple ambient light sensor (ALS). A typical application would be a brightness control for cell-phone backlighting. On a very ...

How hard could it be to turn on an LED? Connect the LED in series with an appropriate resistor and hook it up to a dc source with the correct polarity and voilà, instant LED light. Of course, you can ...

Light emitting diodes (LEDs) are low-voltage light sources that require a constant DC voltage or current to operate optimally. Because they operate on a low-voltage DC power supply, they easily adapt ...
