To emulate the natural soft start of an incandescent bulb, this circuit makes use of the thermal-foldback protection built into an LED-driver IC (MAX16832). It thereby avoids the annoying and almost ...

One of the less obvious differences between incandescent light bulbs and LED-based lights is the speed at which they start up. An incandescent bulb requires some time to reach full brightness after ...

Automotive incandescent bulbs have largely given way to more efficient, reliable, stylish, and even safer light emitting diodes (LEDs). LEDs turn on in a fraction of the time and are especially useful ...

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 ...

The quest for energy efficiency has led manufacturers to investigate ways of dimming all kinds of lighting technologies, including those that usually can’t be dimmed. Consider, for example, ...

LED lighting will drastically reduce energy expenditure, significantly reduce greenhouse gases, and provide lighting designers with increasingly sophisticated options—but only with driver technology.
