IOWA CITY - The City of Iowa City and MidAmerican Energy have signed an agreement to convert the city's roughly 4,000 street and pedestrian lights to light-emitting diode, or LED, units over the next ...

This application note describes the LED driving system using a half-bridge LLC resonant converter for high power LED lighting applications, such as outdoor or street lighting. Due to the existence of ...

It’s of course true that LED headlights on luxury cars and other new cars definitely look better than traditional halogen headlights, but the benefits reach far beyond looks — they’re also much safer ...

Controlling the brightness of LEDs requires a driver that provides a constant, regulated current. To achieve this goal, the driver topology must be able to generate a large enough output voltage to ...

Due to their light output and long life, high-brightness LEDs are well-suited for use in flashlights. Typically, the LEDs are driven with a constant current. So when the battery voltage drops, the ...

ON Semiconductor's CAT4106 is a 6 W LED driver with an integrated, high-power dc-dc boost converter and on-chip diagnostics to maximize efficiency in larger, general purpose LCD panel backlighting ...

Catalyst Semiconductor, a supplier of analog, mixed-signal and non-volatile memory semiconductors, has expanded its line of high-power LED drivers with a new device optimised for the mid-size LCD ...
