Optimised for non-directional and small LED replacement lamps such as B10 candelabra, E17, GU10 and A19 bulbs, Cree XLamp® XT-E and XM-L High Voltage White LEDs deliver both high lumen output and high efficacy in a small footprint. Unlike other high voltage LEDs in the market, you do not have to compromise between size and efficacy.
The image below shows the difference in size between the driver circuit for high voltage and standard voltage LEDs. The high voltage LED driver circuit on the left is much smaller than the low voltage LED driver circuit on the right.
Less Power Wasted = More Lumen Output!
In a shared heatsink system, heat from the power supply can lower the LED lumen output. A cooler system can enable higher lumen output. All of these system optimisations can lead to more efficient, better and cost-effective LED lamps and luminaires, allowing you to provide better and cheaper products to your customers.
Peter Vaughan, Director of Applications Engineering at Power Integrations said: "Maximising the LED voltage, as Cree has done in the new XM-L High Voltage and XT-E High Voltage LEDs, is a very effective way to minimise current through the LED driver output rectifier. This reduces losses and heat dissipation in the driver and increases the overall system luminous efficacy by several percentage points."
