Calculating Power Supplies for LED Strip Lights



When you are organizing on installing LED strip lights (also known as LED tape) you have to be able to accurately calculate the power expected. Obtaining insufficient power provide will bring about only some (or none) of your LEDs illuminating, or can cause irritation flicker. An over specified power supply will cost additional to get, and will also be harder to fit as they are bigger. Get much more details about LED Driver

To calculate the power provide needed for the new LED strip lights, you should know:

Length with the strip or tape
Number of LEDs per metre
Power consumption per LED

To calculate the size of power provide (in Amps) you need to multiply the length of the LED tape by the amount of the LEDs per metre and then multiply this by the power with the LED (0.08w to 0.24w per LED are common values). Then divide the value by 12 volts to calculate the expected Amperage in the power supply.

(Length of LED Strip x LEDs per Metre x LED Power) / 12

We propose you add a minimum of 10% to the calculated value to permit for resistance and losses in the cables. You would also need to have to allow for any doable expansions or additions inside the future. Most LED Strip Lights can have more sections added using joining cables.

Calculation Examples:

Example 1: A 5m roll of SMD3528 (0.08w) with 60LED/m could be: (5m x 60 x 0.08) / 12 = 2amps +10% = 2.2Amps.

Example 2: A 5m roll of SMD5050 with 60LED/m could be: (5m x 60 x 0.24) / 12 = 6amps +10% = 6.6Amps.

For any LED strips over two metres in length you may deliver a 12volt feed to both ends on the strip or one particular feed in the middle, by cutting the strip into two and connecting the power supply to each strips. This offers a far more even power distribution and ought to supply a extra consistent illumination.

LED Strip Light Utilizes

There are actually two most important factors for working with LED strips. One particular is efficiency - LED lights are extremely effective, with most of the power going to generate light, not heat. Their particularly extended life (20,000 hours is standard) implies that in addition they usually do not want replaced pretty normally, major to vastly reduced lifetime charges.
