Cree enhances XLamp CXA2 LEDs
Flagship chip-on-board LED family delivers higher reliability, efficacy and new premium colours
Cree has announced enhancements to its XLampCXA2 family of chip-on-board (COB) LEDs, including new premium colour options, higher light output levels and the longest lifetimes published for this type of LED.
The premium colour quality options include high fidelity (98 CRI) and specialty colour points for the 9 to 19 mm LES sizes with up to 50 percent higher efficacy than LEDs of similar sizes and light quality. These enhancements to the CXA2 family LEDs give Cree's customers the ability to upgrade the performance of existing designs and to sell their products into lighting applications where colour quality is important, such as museum, retail and medical lighting.
"The leading efficacy and excellent reliability of Cree's CXA2 LEDs allow us to create a complete portfolio of high quality, energy efficient LED track lights," said Eric Lin, general manager, Westport International. "With the new premium colours, the CXA2 family will allow us to bring these same advantages to more customers and applications while still leveraging the same, easy-to-use platform."
The CXA2 Standard Density LEDs now deliver up to 10 percent higher light output levels across all CRIs and light emitting surface (LES) sizes, providing the highest COB LED efficacy for all applications. The CXA2 LEDs are claimed to be the only COB LEDs in the industry to have more than 11,000 hours of LM-80 data available. Based on this data, the CXA2 LEDs provide L90 lifetimes well beyond 60,000 hours, even at extreme 105degC test conditions.
"With these enhancements to the CXA2 family, Cree continues to set the benchmark for high-power LEDs through constant focus on improvement," said Dave Emerson, Cree LEDs senior vice president and general manager. "With the industry's best lifetime and the new premium colour offerings, we're giving lighting manufacturers the ability to deliver better light and industry-leading performance to more applications than ever before."
