For automobiles, especially motorcycles, auxiliary lighting that augments the headlights can be quite useful, particularly when you need to drive/ride through foggy conditions and poorly lit or unlit ...

This is a simple flashing led circuit with 2 leds and 2 NPN transistors. It illustrates the behavior of transistors and capacitors and if you use an oscilloscope it will be very easy to determine what ...

Lighting a string of LEDs at a constant brightness requires driving it with a regulated current. A boost converter is commonly used to step up the voltage to a level high enough to bias the LEDs on ...

The advent of LED lighting in the past few years has now matured to the point where sweeping changes exist in the way we think about illumination. LED lighting was once the darling of scientists and ...

INDIANAPOLIS — Welcome to Home Zone! Today, we’re upgrading outdoor lighting with an easy and modern solution — plug-in LED lights. If you’ve been dealing with old, unreliable transformer-style lights ...

[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] ...

Supertex has introduced an LED lighting chip with switch dimming. The IC, dubbed HV9801A, dims LED lamp brightness to one of four preset levels through rapid toggling of a light switch. Light levels ...

This resource provides clear explanations of how switching regulators work and how voltage boosting is achieved efficiently in practical circuits. A Joule Thief circuit is a small, energy-efficient ...

So, your company has decided that it has either found a niche market or an industrial customer(s) with a sufficiently large volume to justify a business case for some kind of LED lighting. Now what?
