BXRC-35G10K0-D-73 Application Field and Working Principle

The BXRC-35G10K0-D-73 module is one of the newer members of the Cree family of ceramic packages offered in differing sizes and dimensions. This model is a 35W surface-mount package designed for optimal thermal management and performance in lighting applications. It functions entirely as a constant-current source, with no additional components or circuitry in its electrical schematics.

This module is commonly used in commercial and industrial lighting applications, with its high power making it ideal for lighting projects with intensive energy requirements. These include streetlights, ornamental lighting, and other large-scale public lighting installations. It is also used in floodlighting, parking lot lighting, and other applications requiring high intensity source of light. Its various features and benefits further enhance its viability in many diverse lighting projects.

Working Principle of BXRC-35G10K0-D-73

The module operates on the principle of constant-current operation. This means that the output current of the module does not change, regardless of the load applied or environmental conditions. This is due to the presence of a feedback system that keeps the output current constant despite changing conditions. This also helps ensure longer hours of reliable lighting, even in harsh climates.

The module works by using a current regulation circuit to detect the output current, and then modify the current through the feedback control loop. The feedback loop consists of two important components: an optocoupler, to detect the current; and a series-connected MOSFET, to change the current level.

The current detected by the optocoupler is routed to the MOSFET, driving the current through the device until the set current level is achieved. This high-precision regulation circuit ensures that the current is always kept at the optimum level, regardless of load or environmental conditions.

The module also features over-temperature, under-voltage, over-voltage, and open-circuit protection for added safety and reliability. These safeguards help ensure that even if the module is subject to incorrect inputs or environmental conditions, its operation is not affected.
