SAN JOSE, Ca. - Philips Lumileds today announced its new cool-white Luxeon K2 with TFFC LED. Chip and packaging advancements by the company enable extended capabilities that deliver maximum performance in any environment. Luxeon K2 with TFFC is the only LED designed, binned and tested for standard operation at 1000 mA and capable of being driven at 1500 mA. Thin Film Flip Chip (TFFC) technology contributes to overall light output improvement, excellent optical performance and improved thermal capability. New packaging advancements improve what is already the industry’s most rugged and capable package and deliver the lowest thermal resistance, 5.5 ° C/W, of any power LED; lower thermal resistance allows the LED to be driven at higher currents and lowers thermal management engineering efforts and costs. Light output performance from a Luxeon K2 with TFFC part binned and tested for 160 lumens minimum and 1A drive current can easily exceed 220 lumens at higher drive currents. Luxeon K2 with TFFC leads all LEDs in real-world applications and is designed and manufactured to operate reliably and effectively in the harshest environments.

At its rated drive current, Luxeon K2 with TFFC operates at only 66% of its maximum power rating and delivers unprecedented performance for a single 1mm2 chip. More than two dozen LED drivers available from Future Lighting Solutions are already capable of providing 1000 mA and even higher currents that will allow engineers to take advantage of Luxeon K2 with TFFC’s high drive capability.

Luxeon K2 with TFFC Specifications: (cool-white products)

  • Bin & Test Current - 1000 mA
  • Maximum Current - 1500 mA
  • Thermal Resistance 5.5 ° C/W
  • Max Junction Temperature 150 ° C

Complete specifications are available in the Luxeon K2 with TFFC datasheet (DS60).

Today, virtually every other power LED manufacturer has introduced products at 350 mA but none of these devices can be driven reliably at higher currents without sacrificing lumen maintenance or causing junction temperature to exceed published maximums. None of the other LEDs can be operated at 1A for extended periods of time. In fact, even when datasheets indicate typical values at higher drive currents, they are not achievable in actual applications.

The advantages of Luxeon K2 with TFFC’s high drive current ratings to the lighting community are many. For applications like security lighting, roadway lighting, automotive lighting architainment or spot lighting where maximum light and robustness are required while still delivering improved efficiency, Luxeon K2 with TFFC can be implemented to engineer the most cost effective solutions that consider all costs including the thermal management system, drive electronics, optics and LED count. The ability for designers to increase current without increasing thermal management size or cost to the same degree ultimately results in a lower cost of light.

“Customers are already making the move to 1000 mA drive currents and higher to take advantage of higher light output and improved efficacies,” said Erik Milz, Product Manager at Philips Lumileds. “Incorporating TFFC technology and package improvements gives us the best LED for the most demanding applications and environments such as automotive, signaling, general lighting and architectural applications. Using a single chip allows for the smallest optical source size making it easier to design optics such as reflectors, diffusers and lenses that are essential for most applications.”

Luxeon K2 with TFFC offers industry leading lifetime and reliability. This information is detailed in Philips Lumileds graphical reliability and lumen maintenance tools available on the company’s web site and in Reliability Datasheets. Luxeon K2 with TFFC is also compatible with much of the complementary infrastructure for electronics, optics and thermal solutions already in place for Luxeon K2 LEDs.

Availability

Luxeon K2 with TFFC in cool-white is available from Future Lighting Solutions (FLS) (www.futurelightingsolutions.com). Contact FLS for pricing and availability of specific flux bins. Philips Lumileds is preparing for volume production of neutral-white and warm-white to be followed by royal blue, blue, cyan and green. Future Lighting Solutions can also advise on appropriate driver and thermal management systems to ensure the most effective operation of Luxeon K2 with TFFC in any application, any environment.
