In this post, two LED blinking circuits are given below. First one is dancing bi-color LEDs (two different color LEDs) where the two color LED will run in sequence. In the second circuit, we will ...

Due to the advantages like low voltages, long life, cheap, reliable, fast on-off switching etc, the LED’s are used in many applications. The various applications of LED are, All kinds of visual ...

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 ...

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 ...

LED-driver circuits can be dimmed by applying a variable duty cycle (pulse-width modulation, or PWM) to the LED. PWM exploits LED behavior: At higher current levels, the LED’s light output is higher ...

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?

Guest columnist Faraz Hasan, marketing and business development manager at Tyco Electronics Circuit Protection Products says that LEDs can require overcurrent protection despite built-in safety ...

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 ...

Businesses, municipalities, and universities from coast to coast have embraced the long-term benefits of LED lighting. However, many organizations miss out on additional ...

This simple 4093-based audio peak detector from December 2004 monitors music and turns on a small light when the sound gets ...
