LED power supply provide some method of voltage division to meet LED Strip Lights/Neon LED Flex needs.
Filter pulsating dc voltage to a pure dc steady voltage for LED Strip Lights/Neon LED Flex use. Change ac voltage to pulsating dc voltage by either half-wave or full-wave rectification. Regulate power supply output in proportion to the applied load.
A power supply is an electronic circuit that converts the voltage of an alternating current (AC) into a direct current (DC) voltage. It is basically consisting of the following elements: transformer, rectifier, filter and regulator circuits.
Whether you are building your own LED Strip Lights, fixing and retrofitting existing LED fixtures, or purchasing new Neon LED lights, you need to find the correct power source for your LED Products.
It not difficult to choose led lights power supply.
The LED Strip or Neon LED Flex usually with input of DC5V, DC12V or DC24V, it very important not make wrong voltage. When building an LED fixture or replacing a bad power supply, it is important to first verify that the output voltage is compatible with the LEDs voltage. LED products with built in current regulators will usually be pretty good about specifying what input voltage should be used.
Or the LED Fixture will not work, sometimes will be destroy.
After confirm the Voltage, find out how many watts your light will consume. Make sure to have a large enough power supply by giving yourself a 20% cushion over the total wattage you calculate from your LEDs. If you hope to run more than one light off of one power supply, you must sum the wattages up to find the total watts used. This can easily be done by multiplying your total wattage by 1.2 and then finding a power supply rated for that wattage.
For example, 80w indoor LED Strip need 1pcs 100w power supply
If your LEDs are dimmable and you would like to adjust their brightness, make sure you choose a power supply that has dimming capabilities. Power supply specifications should list whether a power source is dimmable or not and what dimmer control type it uses.
The solution for Normal Power Supply + Dimmer Controller will make a better dimming function. Because Dimming Power Supply always control the brightness by Adjust Current which are not accurate.
