The limits of powering LEDs

Limits of powering LEDs

Large-video displays present a power design challenge; how best to develop an efficient solution that reduces energy losses, minimizes heat generation and is easily scalable. Heat can be a big problem with LEDs. More heat results in excessive temperatures, which rapidly degrades LED luster and longevity.

Delivering brighter LEDs that last longer

Driving thousands of LEDs in a large-scale video display requires an efficient power system to produce the low-voltage, high-current supply needed. Traditionally designers have turned to a PoL solution that uses 24V as the intermediate DC voltage. Increasing the voltage to 48V though reaps numerous benefits that 24V just can’t deliver including reduced heat generation, reduced cabling, size and weight, increased LED performance, longer panel life and higher power efficiency.

Application examples

Video wall display

The challenge of installing a display of enormous size and weight, with its associated cabling, only became feasible with a move to a Vicor component-enabled, higher voltage bus.

Passenger bus LED display

High efficiency over a wider input range and mounted on the same board as the LEDs, Vicor ZVS buck regulators eliminated hot spots around the power supply thereby correcting color variances of the LED display.
