LED Lighting - COBs, Engines, Modules

The CXA1304-0000-000C00C250H is one of the latest additions to a wide range of COB (Chip On Board) solutions from Cree. The CXA1304-0000-000C00C250H is designed for high lumen applications such as downlighting, architectural, retail, and commercial lighting applications. This COB provides high efficacy, excellent color consistency, and superior thermal management capabilities, making it a great choice for lighting designers.

Applications

The CXA1304-0000-000C00C250H is ideal for a variety of interior lighting applications, such as residential, commercial, retail, and alighting applications. It is has the ability to provide high quality and consistent illumination to any area with added bonus of energy efficiency. High efficiency versions of the CXA1304-0000-000C00C250H can offer up to 140lm/W efficacy with color temperature ranging from 2700K to 6500K.

The CXA1304-0000-000C00C250H is also suitable for outdoor lighting solutions. Cree\'s electrical and optical design allows the CXA1304-0000-000C00C250H to provide consistent lighting in both dry and wet conditions. Due to Cree\'s powerful thermal management, this COB is able to operate efficiently in temperatures up to 110°C.

Working Principle

The CXA1304-0000-000C00C250H is a versatile low-voltage COB that utilizes Cree\'s patent-pending CeramiCool thermal heat management technology. This COB is designed to introduce a relatively minimal incremental thermal resistance, enabling it to operate at high-temperatures and with high-efficacy. The CeramiCool technology provides the emission of heat in all directions, which allows the COB to run cooler, while eliminating any hotspots.

The CXA1304-0000-000C00C250H is compatible with most leading constant current drivers, such as Mean Well and Inventronics, and is suitable for both DC and AC currents. Cree\'s Pulse Width Modulated (PWM) driverless design is compatible with all high power implementations, allowing the COB to be used for calculations of the Phase-Cut Dimmer, and allowing for the regulation of the CRI for applications that require more subtle and pleasant lighting.

Cree\'s CXA COBs are designed for both high and low-voltage applications. The COB operates from a wide input voltages ranging from 17V to 34V, allowing for easy system integration into single sided and two sided solutions. The CXA1304-0000-000C00C250H utilizes Cree\'s proprietary chip-on-board type VII packaging technology that incorporates a single package design with multiple LED die and driver components. This packaging technology serves to lower the optical reflectance while improving thermal conduction and optimizing dimming performance. It also reduces the risk of electrical issues associated with LED bulbs and conventional drivers.

Overall, the CXA1304-0000-000C00C250H is an energy-efficient and high quality COB solution for applications such as residential, commercial and retail lighting. It offers high efficacy, excellent color consistency, and superior thermal management capabilities that make it a great choice for lighting designers.
