Cree (NASDAQ: CREE) has recently introduced the XLamp High Current CMA series, a groundbreaking advancement in metal-based COB technology. This new line offers enhanced lumen density and efficiency, making it ideal for high-power lighting applications. The CMA series is designed to deliver superior performance while maintaining compatibility with existing systems, enabling manufacturers to boost output without major design overhauls.
The CMA Series COB devices are specifically optimized for large drive currents, delivering up to 2.5 times the lumen density of the standard density CXB series. This means more light output in the same space, which is particularly beneficial for designers looking to create brighter, more efficient lighting solutions. Additionally, the CMA series is fully compatible with current fixed couplings and optical packages used in the CXB series, allowing for seamless integration into existing product lines.
Andrea Gallucci, head of the optical and electronics division at Artemide, praised Cree's commitment to innovation, stating, “Cree is a highly innovative partner in the LED lighting industry, always focused on meeting customer needs. The compatibility of the high-current CMA series with the standard-density CXB series makes it easy for us to provide greater visual impact while maintaining the same optical options and color quality that our customers expect. The new CMA series will bring significant performance improvements to our signature and innovative luminaire designs.â€
What sets the CMA series apart is its use of advanced metal-based COB technology, which provides improved reliability compared to other competitive options. Furthermore, the ability to mount these components directly onto heatsinks simplifies the manufacturing process and reduces overall system costs, offering both performance and cost benefits.
Dave Emerson, Executive Vice President and General Manager of Cree LED, highlighted the technological advancements behind the CMA series: “Through continuous innovation, our scientists have achieved fundamental breakthroughs that significantly enhance the light output and lumen maintenance of the CMA series beyond current metal-based COB technologies. Cree’s ceramic-based and metal-based COB solutions offer superior lumen density and reliability, tailored to meet the evolving demands of our customers.â€
The CMA series currently includes five COB devices, with luminescent surface sizes ranging from 9mm to 23mm, ensuring flexibility across various applications. It features Cree EasyWhite binning, a wide color temperature range from 2,700K to 6,500K, and standard CRI options of 70, 80, and 90. For those requiring exceptional color accuracy, the series also includes high color fidelity (98 CRI) and premium color options for special color points.
Samples of the CMA series are now available, and mass production can be arranged according to standard lead times. Whether you're designing commercial lighting or high-performance luminaires, the CMA series offers a powerful and flexible solution that combines innovation with practicality.
