PT-54-R-C21-MPC application field and working principle：

PT-54-R-C21-MPC is a high-power single-output LED COB which is developed for high density, high luminous flux applications. It provides excellent light quality and wide compatibility with industry standard color temperatures, CRI，efficiency, luminous flux and chromaticity. PT-54-R-C21-MPC is applicable to commercial lighting, downlights, troffers, accent lighting and linear lighting. This LED COB with its WLED module reaches 230 lm/W.

The working principle of PT-54-R-C21-MPC is to use low voltage-high current LED driver and constant current LED driver.Low voltage LED Driver is a LED drive that is powered or driven by the low mains voltage,whereas Constant Current LED Driver is a device that helps maintain a constant current passing through the LED.

The PT-54-R-C21-MPC’s low-voltage high-current LED driver operates by increasing the voltage to create a high current that is then transferred to the LED. The current is actively reduced by a current sink, which compensates for changes in either applied voltage or temperature. This type of driver is not affected by changes in the capacitance of the driving circuit.

The constant current LED Driver monitors the current passing through the LEDs. When a change in voltage is detected, the driver compensates by adjusting the output current. This helps to ensure consistent operation of the LEDs over the entire input voltage range.

The PT-54-R-C21-MPC also utilizes advanced thermal design for efficient heat dissipation and long life. The aluminum pcb helps to ensure sufficient heat exchange, and the special design of the heatsink and body eaned that the COB is highly reliable and light efficient. The unique hybrid construction benefits from both thermal conductivity and electrical isolation.
