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 ...

Part 2: A 60V buck-boost controller drives high power LEDs, charges batteries and regulates voltage with up to 98.5% efficiency at 100W and higher. Part 3: Offline LED lighting simplified: A high ...

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 ...

Pivotal design areas are the driver and its power converter. These sections of an LED lighting assembly have the greatest influence on achieving performance objectives. Similarly, protective devices ...

The design of luminaires for solid-state lighting is still part black art. The best approach starts with the light output and an artistic arrangement of LEDs.

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).

It delivers a scalable, efficient, and reliable solution for rear vehicle LED lighting, featuring fault detection, thermal ...

A Simple Over-Voltage Protection Circuit for LED Drivers This boost circuit implements current mode control and senses the LED current via resistor R14. The output voltage is boosted to just over 30V ...

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 ...

As the LED lighting market continues to grow across application segments, the demand for high-reliability in the lighting industry, and return on investment continues to increase. Given those ...
