The CMA module is Cree's advanced COB solution with higher flux density and improved thermal performance compared to the CMB series. The CMA series incorporates newer LED technology with enhanced efficacy and luminous density, making it suitable for applications requiring maximum light output in a compact form factor. It also features an improved thermal design for better heat dissipation.
CMA modules require careful attention to thermal management and electrical connections. The module must be mounted to a suitable heatsink using thermal interface material with low thermal resistance. Proper cleaning of surfaces and correct mounting pressure are critical for optimal thermal performance. Electrical connections must be made with appropriate wire gauge and connectors rated for the operating current.
Yes, CMA modules can be used in outdoor applications when properly integrated into a luminaire with appropriate environmental protection. The modules themselves are designed for harsh environments, but the overall system design must provide adequate protection against moisture, dust, and temperature extremes. Proper sealing and IP-rated enclosures are essential for reliable outdoor operation.
