Typical Wiring Schematic



110V/220V led strip VS 12V/24V led strip lights

LED strip is very hot all over the world. It mains included high voltage led strip and low voltage led strip:

1) 110V or 220V LED strip(High voltage strip)

2) 12V or 24V led strip

What is the difference?

1, Input voltage

High voltage led strip can be plug in wall socket directly, low voltage need 120v/220v to 12v/24 voltage converter.

2, cutting

High voltage led strip cut by every one meter or 0.5 meter, low voltage led strip cut by every led or 3 leds.

3, installation

High voltage led strip just use mounting clips and screws, low voltage led strip use double side tape, mounting clips and screws.

4, safety

Low voltage led strip is more safe. It can be touch when powered on, as to high voltage led strip, people must powered off when you want to touch.

5, running length

Running length is high voltage advantage, they can run 100M Max. continue, but low voltage just can run 5M or 10M max.

6, waterproof

All high voltage led strip is waterproof, but low voltage have IP22,IP65 and IP68 waterproof rate difference.

7, control

For RGB led strip, high voltage it is hard to control the color change, but low voltage will be easy more by general controller, DMX system, DALI system, amplifier controller, etc…..

8, brightness

Because high voltage led strip’s silicon protection cover, the lumen will be discounted.


Calculate the suitable transformer for RGB LED Strip

The power supply you need will depend on the TYPE of the LED flex strip light you are using for your project. The correct power supply needed for your LED lighting project is easy to calculate.

Step 1 Which LED strip light brand will you use?

The first step is to choose which flexible LED strip light you are going to use for your project.

Step 2- What length of LED strip light do you need ?

The power source needed depends on the length that you cut the LED strip. Let’s use the 150 LED RGB strip light as an example: Each meter uses 7.2 watts. Add the amount of lenght together, multiply by 7.2, and you have the wattage used. You should add 20% more room in the power supply so take the wattage, and divide by .8 to get the power supply needed.

Example. 8 meter of RGB LED strip light. 8 X 7.2 watts = 57.6 total watts used. 57.6/.8= 72 watts. You need a power supply that will handle 72 watts.

Price different between the LED lights

In recent years,the led market is very fast developing.However, the price of all kinds of LED lights are have some distance,and the quality is different too.

Now the led light is nearly has the same market as the energy saving lamp.And more and more customers will buy LED light more than the energy saving lamp.LED is new technology,compared with energy saving lamp,the light is better,more power and longer lifespan. For example,the brightness of a  20-watt LED lights will better than 40-watt energy-saving lamps,and power consumption can save more than half.

Each led company will have different led brand chips for selling,and also there is a big difference in price between different products.For example,the price of the 5W LED spotlight, the ranging from 2USD to 8 USD, some even up to more than 13USD.Why there is some big different?The reason is quality,material,the light effect and life span are different.When you compared the led spots,you will feel the expensive one will much heavy,the led driver is not the same too,you also can see the different on the appearance.And the light of the expensive spot will much soft and with good lighting.About the cheap spot,you will find the light dim after a half year using.

But now almost all the led suppliers said the lifespan of the led lights are 30000-50000hours,but when do the guarantee is only 1-3years.The lifespan of LED lighting seems to be a “concept” for the customers.It is hard for the customers to choose a good led product.But pls trust us,we will be your reliable led partner.

PWLED-RGB systems

White light can be produced by mixing differently colored light, the most common method is to use red, green and blue (RGB).
Hence the method is called multi-colored white LEDs (sometimes referred to as RGB LEDs). Because its mechanism is involved
with electro-optical devices to control the blending and diffusion of different colors, this approach is little used to produce white
lighting. Nevertheless this method is particularly interesting in many applications because of the flexibilityof mixing different colors,
[55] and, in principle,this mechanism also has higher quantum efficiency in producing white.

There are several types of multi-colored white LEDs: di-, tri-, and tetrachromatic white LEDs. Several key factors that play among these different approaches include color stability, color rendering capability, and luminous efficacy. Often higher efficiency will mean lower color rendering, presenting a trade off between the luminous efficiency and color rendering. For example, the dichromatic white LEDs have the best luminous efficacy (120 lm/W), but the lowest color rendering capability. Conversely, although tetrachromatic white LEDs have excellent color rendering capability, they often have poor luminous efficiency. Trichromatic white LEDs are in between, having both good luminous efficacy (>70 lm/W) and fair color rendering capability.

What multi-color LEDs offer is not merely another solution of producing white light, but is a whole new technique of producing light of different colors. In principle, most perceivable colors can be produced by mixing different amounts of three primary colors, and this makes it possible to produce precise dynamic color control as well. As more effort is devoted to investigating this technique, multi-color LEDs should have profound influence on the fundamental method which we use to produce and control light color. However, before this type of LED can truly play a role on the market, several technical problems need to be solved. These certainly include that this type of LED’s emission power decays exponentially with increasing temperature,[56] resulting in a substantial change in color stability. Such problems are not acceptable for industrial usage. Therefore, many new package designs aimed at solving this problem have been proposed and their results are now being reproduced by researchers and scientists.
