What is CC and CV in power supply? Jun 06 ,2019
"CV" in the name of "constant voltage" and "CC" in the name of "constant current". They are usually associated with LED power supply or some kind of indicator. When using a power supply, it is normally necessary to set the required voltage and maximum current Most types of loads require a "CV" ...

What is a lamp driver? Jun 05 ,2019
Traditional incandescent and fluorescent lamps are power-driven devices that can be used directly with 240V 50Hz AC power. Today, however, these have gradually been replaced by more efficient, longer-life LEDs that typically operate at 12 volt dc led power supply. Therefore, LED lights must have a p...

How to use led driver correctly May 28 ,2019
Due to the increased use of energy regulations, most people are now familiar with the life and energy savings associated with LEDs or light-emitting diodes. However, many people do not know that these light sources require a special device to operate, that is, the LED driver. LED drivers (also known...

What causes the different colors in LEDs? May 24 ,2019
The working principle of LEDs is based on photon emission. The light emitting diode is essentially two oppositely doped semiconductors that are joined together to form a p-n junction. Doped semiconductors are used to enhance their conductivity. LED power supply can be done in two ways:The introducti...

What does a power supply consist of? May 20 ,2019
The basic unit of the power supply are: transformers, rectifiers, filters and voltage regulator circuits. The power unit uses all other electronic equipment with DC voltage as input. Its function prevents data corruption due to power failure and low voltage. Rectifiers, and filters are the three mai...

What is a regulated power supply? May 16 ,2019
The regulated power supply is a built-in circuit. With the help of a rectifier, the AC(alternating current) is transformed to DC(direct current). It has the ability to provide a regulated voltage (or lower frequency current) for circuits or devices that must operate within a certain power limit. The...
