Once we have it, the calculation is very simple. We multiply the meters of our LED strip by the power of said strip, and then multiply by 1.20 in order not to overload the power supply.

How to know the number of volts that an LED strip needs?

1. Voltage: LED strips with SMD chips work with direct current, the most common voltages being 12, 24 or 230 volts. Therefore, we will need an AC-DC power supply, which converts alternating current to direct current, and which in turn transforms it to the working voltage of the strip.

How to know the amperage of an LED strip?

A continuous voltage of 2 -3.6 Volts must be applied to each LED for correct operation, which will achieve a current of the order of 0.02-0.03 Amperes. In these average conditions, the light emitted by each chip will be of the order of 5.5 lumens.

How much does a 1 meter LED strip consume?

Consumption (Depends on the type and number of Leds)

– 60 SMD 3528 LEDs per meter – 5 W each meter of strip. – 120 SMD 3528 LEDs per meter – 9 W each meter of strip. – 60 SMD 5050 LEDs per meter – 14.4 W each meter of strip. – 72 SMD 5050 LEDs per meter – 17.3 W each meter of strip.

How much does a 5 meter LED strip consume?

A common RGB LED strip of 5 meters usually consumes about 24 W with a voltage of 12 volts. After reviewing many of the LED strips that are sold on Amazon Spain, we can ensure that almost all of them have exactly the same energy consumption.

How much does LED strip spend?

A 1.3W/m strip uses 6.5 watts for a 5 meter strip, but 13 watts for a 10 meter version. So to answer the question: how much energy do LED strips use? It depends on the length of the strip and the power consumption, depending on the light density and the size of the diode.

How much does each LED strip consume?

Its light efficiency is high, around 60 lumens per watt. The most common are 3528, which are small and low power, with a consumption of 5w per meter, used when it comes to LED strips for decorative lighting.

What is the difference between 3528 or 5050 LEDs?

The SMD 5050 LED strips have a size of 50mm x 50mm, being larger than the SMD3528 strips. It is a type of LED strip with higher power and consumption, which also implies a higher luminous flux than SMD 3528 LED strips.

Which LED is better 5050 or 2835?

Benefits of SMD 2835 LEDs

The novelty in strips is the development of the new SMD 2835 LED, which makes better use of the chip space and provides the same brightness as the SMD 5050 but with lower consumption, which is why it turns out to be one of the most efficient products on the market.

How many volts does an LED lamp need?

LED voltage drop, it is the necessary voltage for the operation of the LED, it is generally between 1.7 and 3.3 volts, it depends on the color of the diode and the composition of metals.

How many volts is an LED?

LEDs are relatively tolerant in terms of current, so it can be varied between 5mA and 15mA for indicator LEDs and between 15mA and 30mA for high brightness LEDs (between the latter, white and blue).

What voltage do LED lamps use?

The LEDs integrated in any type of LED Strip generally work with very low voltages, commonly from 2.5 to 3.5v. For the LEDs to work at 12v, they are grouped in series of 3 to divide the voltage for each led (12v/3= 4v).

What does 2835 mean in LED lights?

SMD 2835 is the newest SMD configuration and offers the best cost/performance. It is significantly smaller than the SMD5050 and has better heat dissipation. Oversized light-emitting surface improves light rate up to 90%. The ultra-thin structure solves the problem of 3528.

What does 2835 LED strip mean?

SMD 2835 LED strips

They are single-core chips and therefore capable of reproducing only 1 color per LED (white, blue, red, yellow, green).

How many lumens does a 2835 LED give?

It offers a brightness of 22 lumens per LED, so the SMD2835 LED strip is the most suitable for installations with high brightness requirements since its cost per lumen is lower.

What does 5050 LED type mean?

What do these numbers mean? Fortunately, they are not randomly assigned digits, but determine the size of the LED diode, for example, 5050 LEDs measure 5.0mm x 5.0mm, while a 3528 measures 3.5 x 2.8mm respectively.

What do you mean 5050 LED strip?

Led strips 5050

These led strips are called SMD 5050 because the chip dimensions are 5.0mm x 5.0mm. These led chips contain 3 led chips in one frame (sometimes called tri-chips) and are much brighter than 3528 led strips.

What voltage does SMD 2835 LED have?

SMD 2835 0.5W high voltage led 6v 9v 18v with datasheet.

How many LEDs can be connected to 12V?

THE MOST USED CONNECTION IS 3, 4 or 5 LEDs IN SERIES PLUS A RESISTOR, AND A 12VDC OR 24VDC CONNECTION.

How much does a 12V LED consume?

How much energy does an LED strip consume? A common RGB LED strip of 5 meters usually consumes about 24 W with a voltage of 12 volts.

What is the voltage of a lamp?

Volt or voltage indicates the electrical voltage of a lamp. The power supplied to your home is 220/230 volts as standard. Most lamps just work on this. However, there are exceptions, such as recessed spotlights, some of which run on 12 volts.

How to connect leds in parallel to 5V?

If the LEDs are white or blue, we must connect them in parallel because by putting them in series, the sum of the voltages of each one would exceed the 5V of the USB port and therefore they would not light up. The best way to connect them in parallel is by adding a series resistor for each LED that we put.

How many watts should a lamp have?

Incandescent: 60 W. Low consumption: between 13 and 15 W. LED: between 10 and 15 W.

How many watts bedside lamp?

For the nightstand, you can use the 8 or 12W Mini Twister lamps, which also have a useful life of 8,000 hours.
