Input voltage:
That is, the voltage value required for the normal operation of the LED lamp, according to different countries have different input voltage values, we usually refer to the civil full voltage is AC85~264V.
input power:
Input power refers to the product of the input voltage and input current of various types of electrical components, that is, the power supplied by the power supply or the power grid to various types of electrical devices. Unit - Watt (W) Pi (input power) = Vin (input voltage) * Ii (input current)
Power factor:
Also known as the power factor, the English abbreviation PF (Power Factor), is the ratio of active power to apparent power. The power factor reflects the proportion of electric energy that can be utilized to a certain extent, and is an important indicator for rational use of electricity.
Constant current accuracy:
Constant current accuracy means the ratio of the output current fluctuation value to the rated output current when the input voltage of the driving power supply varies within a certain range, usually expressed as a percentage. For example, the rated output current of an LED driving power supply is 0.45A, when the input voltage is at When the AC80~264V changes, the measured output current varies between 0.43-0.45, then the constant current accuracy = (0.45-0.43) ÷ 0.45 ≈ 0.045 = 4.5%. The higher the constant current accuracy, the better the LED works, and vice versa. There will be stroboscopic phenomena, and even more serious will lead to LED failure.
Electromagnetic Compatibility:
Electromagnetic compatibility (EMC) refers to the ability of a device or system to function properly in the electromagnetic environment in which it is located and does not constitute unacceptable electromagnetic disturbances to anything else in the environment (eg, causing the radio to fail to play properly, causing the television picture to appear And so on).
