LED power supply is a power converter that converts the power supply to a specific voltage and current to drive the LED light-emitting. For example, 48V LED power supply is an LED power supply with an output voltage of 48V.
Usually, the input of LED driver power includes high voltage power frequency AC (i.e. power supply), low voltage DC, high voltage DC, low voltage high frequency AC (e.g. output of electronic transformer), etc.
The LED power supply represented by 48V LED power supply has the following characteristics
1. High Reliability
48V LED power supply waterproof aluminium shell, good quality, not easy to damage, reduce maintenance times.
2. High efficiency
LED is an energy saving product, 48V LED power supply is efficient.It is especially important for the 48V LED power supply to be installed in the luminaire.Because the luminous efficiency of the LED decreases with the increase of the temperature of the LED, the cooling of the LED is very important.The higher the efficiency of 48V LED power supply, the less power it consumes and the less heat it generates inside the lamp, which also reduces the temperature rise of the lamp.It is good for delaying the light decay of LED.
3. High Power Factor
Power factor is the load requirement of power network.There is no mandatory indicator for electrical appliances below 70W in general.Although the low power factor of a single electrical appliance with small power has little effect on the power network.For 48V LED power supply, there is a certain requirement for the size of the power factor.
4. Driving method of LED power supply such as 48v LED power supply
There are two common ways
One is a constant voltage source for multiple constant current sources, each of which supplies power to each LED separately.This way, the combination is flexible and the LED fails all the way, without affecting the work of other LEDs, but at a slightly higher cost.
Second, it is a direct constant current power supply, LED running in series or in parallel.It has the advantage of low cost, but poor flexibility. It also has to solve one LED failure, which will affect the operation of other LEDs.These two forms coexist for a period of time.Multi-way constant current output power supply will be better in cost and performance.This is the mainstream driving mode for LED power supply such as 48V LED power supply in the future.
