Cree Inc, a global leader in the lighting-class LEDs, lighting products, and power and radio frequency semiconductors, has announced the enhancements to its industry-leading XLamp CXA2 family of chip-on-board (COB) LEDs. The product comes in new premium colour options, higher light output levels and the longest lifetimes published for this type of LED, the company has said.
According to the company, the premium colour quality options include high fidelity (98 CRI) and specialty colour points for the 9 mm to 19 mm LES sizes with up to 50% 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 US-headquartered company has also informed that the CXA2 Standard Density LEDs now deliver up to 10% higher light output levels across all CRIs and light emitting surface (LES) sizes, providing the highest COB LED efficacy for all applications.
“With these enhancements to the CXA2 family, Cree continues to set the benchmark for high-power LEDs through constant focus on improvement,” says 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. The CXA2 LEDs are 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 105°C test conditions.” The company has also informed that product samples are available and production quantities are available with standard lead times.
