According to the LED display after the power of the current direction, the overall loss and the voltage of the electrical components of the sum of just 4.5V, this voltage to LED display normal work, laid the use of 4.5V power supply theoretical basis.
4.5V power supply, with the carrier remains unchanged
Furthermore, it is decided that the number of loads is current, not voltage. Power supply voltage can guarantee the normal operation of the screen case, the constant current drive product is the current control type of product, so the product only depends on the size of the power supply current, the use of 4.5V power supply, From the actual use of 4.5V power supply proved the practicality.
With 4.5V power supply, the screen runs more stable
Because the LED display normal operating voltage only 4.5V, the extra 0.5V voltage will be driven by the IC drive, so that the working temperature increased by 15-35%, reducing the service life. At the same time, these heat conduction through the PCB board to the lamp, so that the temperature of the screen body lamp will be increased, thereby speeding up the display in the course of the lamp failure time. We through the hot and cold impact and high and low temperature cycle test practice test, demonstrated the use of 4.5V power supply LED display reliability and stability of the upgrade.
4.5V power more energy efficient, 1 year province 10%
In addition to product reliability and stability of the upgrade, in terms of energy efficiency is also a substantial increase. According to the electrical power calculation formula: power (P) = voltage (U) × current (I), in the current constant, the voltage becomes smaller, the power also becomes smaller. 4.5V power supply than the 5V power supply 10% lower voltage, power is also reduced by 10%, the province of 10% of electricity consumption.
LED display 4.5V power supply, more energy efficient, more protective power supply voltage, the future of LED display power supply new standard. In this, strong giant appeal to the whole industry action, unified power supply standards, continuous improvement of the end consumer confidence in the use of the product experience.
