How to design LED streetlamp driver circuits In many consumer applications for lighting the cost of existing technology – namely incandescent light bulbs or fluorescent tubes – is so low that LED ...

Circuit Protection Requirements All LED drivers need various devices in multiple locations (Fig.2) to protect the circuitry from overvoltage and overcurrent events. Today, there are a few key industry ...

Inspired by printed circuit boards, the building block of all electronics, a Dutch designer has created an LED-based light installation that draws upon the familiar etching pattern inside most ...

The Fig. 1 example includes LED loads D1 + D2, D3 + D4, D5 + D6 and a power-supply output voltage, with a constant output current, providing the circuit input voltage (V IN).

In the industry, I have found that an LED ballast circuit is really more like an AC/DC power supply than like a traditional fluorescent ballast circuit. Today in fluorescent lighting, one need ...

If the LED’s turn-on voltage is lower than the battery voltage, as would be the case with a 6V sealed-lead-acid battery, then you can use a buck converter. Read the associated Circuit Design Idea – ...

Discover the step-by-step process of creating a powerful music reactive LED strip circuit in this comprehensive tutorial.

Suppose we want to drive an LED string with 400 mA. Drivers U1 and U2 (MAX16803) are good for automotive use because they have a high input-voltage range, excellent thermal qualities, and the ...
