c, Wide voltage input DC10-30V light strip
This type of led strip is mainly used in scenes where the DC power supply voltage output is unstable.

10 30v wide voltage input led strip lights - LED Strip Lights Application Guide

For example, in small ships, because of the use of diesel silicon rectifier generators, it will cause the output voltage to fluctuate between DC10-30V. In this case, the DC10-30V wide-voltage lamp strip can be directly used.

2. High voltage AC110V~240V light strip

It uses a high voltage AC power supply. This kind of light strip is mainly used for outdoor lighting decoration, or used for temporary engineering lighting scenes. So it can be used as a flexible work light.

high voltage led strip lights - LED Strip Lights Application Guide

Because it is dangerous to use the high-voltage AC power supply, so it is used in places that are not accessible by human hands. Such as ceilings lighting, trees decorative lighting, etc.

According to the application scenes it can be divided into:

1. Auxiliary lighting strips, using conventional monochromatic lamps. Such as wardrobe cabinet lighting, bedroom background lighting, showcase shelf lighting and so on.

4. Plant growth lighting led strips, using strips made of Special wavelength LED, provide special light to promote plant growth.

5. Sterilization lamp belt for the medical germicidal lamp, using deep ultraviolet LED.

According to the light color can be divided into:

1. Monochrome led strips, such as white color, warm white, red, green, blue, yellow, orange, amber, pink, etc.
Because of the white and warm white is not accurate to describe the color of light, so it is usually replaced by color temperature in the light strip, such as 2700K, 3000K, 4000K, 6000K.

2. RGB led light strip, by synthesizing R, G, B three primary color chips into one LED, so it can separately emit three kinds of the light color red, green, blue.

rgb led strip lights - LED Strip Lights Application Guide

The color light can also be illuminated by three chips together and combined into white color light. If you add an RGB led strip controller, you can achieve a changeable light in sequence and flickers. such as red, green, blue, and white.

3.RGA light strip, similar to the RGB light strip, the only difference is that the RGB LED’s Blue Chip is replaced by the Amber chip in the RGA lamp bead.

4. Double-color light strip, by using any two colors of LED to combine the production of led light strips, the most common is white color + warm white, as well as white color + blue color, white color + red color.

5.RGBW/RGBCCT/CCT led light strip

CCT here means Control Color Temperature, which means that the color temperature of the led strip lights can be adjusted to change between warm white color and white color.

a, The CCT led strip is made from LED in both white and warm white colors. White light color temperature is 2700K, the warm white temperature is 6500K, commonly used lamp beads are 2835 single cup LED or 5050 single cups LED.

CCT led strip lights - LED Strip Lights Application Guide

The led strip light can have a color temperature adjustment range of 2700K~6500K during use, which makes the color temperature selection in the lighting application scene more flexible.

b, The RGBW led strip light is made of RGBW four-in-one LED. The RGBW led strip can not only achieve the color change effect of the RGB led strip, but also can bring another monochromatic light to meet the more demanding monochromatic lighting requirements.

rgbw led strip lights - LED Strip Lights Application Guide

c, The RGBCCT led strip light is an upgraded version of the RGBW led strip.

The RGBCCT led strip light is made of a five-in-one LED. It does not have a fixed color temperature like white color light in RGBW led strip but has two color temperature led chips: a warm white color light, usually 2700K, and a white color light, the color temperature is usually 6500K.

rgbcct led strip lights - LED Strip Lights Application Guide

It covers all the functions of both RGB and CCT led strips, giving a more flexible and friendly lighting experience.

6. The special color wavelength, Such as 390nm, 420nm, 470nm, etc, mainly used for special lighting applications.

According to whether the LED has an IC chip can be divided into:

1. Conventional IC led strip, in addition to the LED and the resistor, the FPC board of this type has a constant current IC chip on it, to control the current of each group of LED to be consistent.

Reduce the impact of plate pressure drop on led strip illumination, Keep the brightness of the head and tail of the led strip consistent.

ic led strip lights - LED Strip Lights Application Guide

This constant current IC chip can also be integrated inside the LED, which can produce another IC led strip, that is, no resistance and no IC chip.

No Resistance High Density Constant Current LED Strip Lights - LED Strip Lights Application Guide

That is, from the appearance, the led strip on the FPC board has only LED, there is no other electronic component. This solution can make the brightness of the led strip more consistent, the appearance is simpler, the LED arrangement is more flexible, and it can be used as a solution for the high-density led strip.

2. Addressable IC led strip, the IC chip on the strip is not an ordinary constant current IC, but an IC chip can be regarded as a pixel.

This IC chip has its own address and can be controlled by receiving controller signals. The signal sent to it can control the level output for different positions of the LED, such as flashing, chasing, jumping, clockwise horse racing, counterclockwise horse racing, monochrome horse racing, color-changing horse, single chasing from head to Tail, flowing water, simulated lightning and the like.

addressable led strip lights - LED Strip Lights Application Guide

The effect of the change of the light strip can be written according to the needs of the customer and can be displayed in the form of a screen, text, letters, pictures, animations, and the like. Common IC chips on the market mainly include WS2811, WS2812, SK6812, P943, Ap102, DMX512 and so on.

The LEDs used in the addressable led strip can be monochromatic LED, RGB LED, or RGBW LEDs.

According to the board material, it can be divided into the flexible led light strip and rigid led light strip

2.The manufacturing process of led strip lights PCB board

It is divided into rolled copper and electrolytic copper.
The PCB made by the rolled copper process has better integrity, better electrical conductivity, and thermal conductivity, but at a higher cost;

copper fpc - LED Strip Lights Application Guide

The PCB made by the electrolytic copper process is slightly worse in overall performance, but will not affect the normal use of the light strip.

copper pcb - LED Strip Lights Application Guide

And because of the convenience and maturity of its production process, it has won the favor of a large number of customers, and the production cost is also lower.

3. The thickness of the led light strip PCB board

The amount of current that the light strip can carry determines the width and thickness of the PCB of the light strip. When the current through the PCB increases to a certain limit, it is necessary to widen or thicken the PCB to ensure that the led light strip works normally.

The width of common light strips is 8mm, 10mm, 12mm, and the thickness of common light strips is 2oz, 3oz, 4oz.

led strip lights thickness - LED Strip Lights Application Guide

Of course, the thicker the board, the worse its flexibility, and there is a risk of pad cracking and board breakage during the winding process.

Therefore, if the working current of the lamp strip is large, it is not that only through thickening the PCB board that the led strip light can work normally. Instead, a variety of potential impact factors should be combined to rationally design the light strip circuit in order to produce a qualified light strip product that meets customer needs.

4. The chip resistor used in the light strip

The conventional lamp strip uses 1206 chip resistor (size: 3.2mmx1.6mm), the max power is 0.25w.

There are also some led light strips with relatively narrow widths. Due to the limited space of the PCB board, 0805 chip resistors (size: 2mmx1.25mm) will be used, and the max power is 0.125w.

1206 resistor - LED Strip Lights Application Guide

5. Outlet method of the led light strip

The end of the conventional monochrome light strip will use 20awg red and black wire as the power supply line, and a thin wire will cause a great safety hazard. Because the voltage of the light strip is low, usually 12V or 24V, then the current of the 12V-12W light strip will reach 1A, and the current of the 12V-120W light strip will reach 10A.

red and black wire - LED Strip Lights Application Guide

So, when choosing the connector wire of the led strip, you should make sure that the wire can carry the working current of the led strip lights. Otherwise, it may cause the power supply line of the led strip to heat up, scorch the connector, or even cause a fire.

The end of the conventional RGB light strip will use RGB-4pin as the power supply line, and the thickness of the wire is 22awg.

rgb 4pin wire - LED Strip Lights Application Guide

6. The size of the PCB pad of the lamp strip

The PCB pad is divided into LED pad, resistance pad and shear port pad
The LED pad and the resistance pad can not be designed too small, otherwise, it will lead to the unreliable LED PCB circuit, and will happen in the situation of dead light when used for a long time.

led strip lights pcb - LED Strip Lights Application Guide

The design of the PCB shear port pad is too small or too narrow, which may lead to weak welding of the power supply line of the led strip; if it is too large, or too much tin is added, the joint solder joint may be too heavy, and long-term use may cause the solder joint to fall off and affect The led light strip use.

8. The back-adhesive used for the led strip light

IP20 non-waterproof led light strips and IP54 glue-proof waterproof light strips are attached with self-adhesive tape on the back of the light strips when they leave the factory for easy installation.

Usually, the adhesive tape used for the light strips is the self-adhesive tape produced by 3M Company. The most common adhesive tape is 300lse

In addition, there are white glue, blue thermal conductive tepe, red VHB tape, etc. Each type of tape has different viscosity.

3M tape - LED Strip Lights Application Guide

Be sure to choose a tape that suits you. Otherwise, the light tape may not be enough adhesive strength because of long-term use and cause the light strip to fall off.

In addition, in order to reduce the production cost of the light belt, some businesses will choose fake 3M tape.

The appearance of this tape is not much different from the real 3M tape. If you don’t pay attention, you can’t distinguish it. This kind of tape is not sticky enough, and it will easily fall off after long time use.

3m back tape - LED Strip Lights Application Guide

Therefore, when you buy a led strip light, you must polish your eyes and distinguish carefully, not to be fooled by the manufacturer.

4. Introduction of the brightness of the LED strip

There are many factors that affect the brightness of led lights, and we will introduce them one by one.

1. The brightness of different types of lamp beads is different.

3528-0.08w-The brightness of a single lamp bead is about 7-8lm
5050-0.24w-24-26lm
2835-0.2w-24-26lm
3014-0.1w-10-12lm
2216-0.1w-10-12lm
5630-0.5w-50-55lm
2110-0.1w-10-12lm

5050 3000K LED Chip Test Report - LED Strip Lights Application Guide

2. USE the same LED chip but different resistances in same PCB circuit, the led strip light’s brightness is different

For example, the following led strips are 2835-120 LEDs/M 3000K Color, and the circuit scheme they choose is exactly the same, and the same LED Chip is also used.

However, the resistance of the first light strip is 120 ohms, and the resistance of the second light strip is 91 ohms, then the second light strip is brighter than the first.

2835 120 LED - LED Strip Lights Application Guide

Of course, it does not mean that the smaller the selected resistance, the better. Each circuit scheme corresponds to a minimum limit resistance value. If it is lower than this resistance value, the light strip will be burned due to overheating.

Therefore, according to actual needs, the purpose of adjusting the brightness of the whole lamp can be achieved by chouse the different resistance schemes.

3. The influence of the length of the light strip on the brightness

Constant voltage led strip, when the length of the light strip is greater than 5m, the voltage drop on the strip will be more obvious, then the voltage of the first LED position and end LED position of the led strip light will be inconsistent, the tail voltage will be lower than the voltage of the first LED.

led strip lights first and end voltage Compare - LED Strip Lights Application Guide

As shown in the figure below, the power voltage is 12.4V, and the tail voltage has dropped to 10.7V, which will cause the problem of inconsistent brightness at the total of the light strip.

Therefore, when the length of the light strip is greater than 5m, this problem can be solved by supplying power at both ends, as shown in the following figure.

led strip lights power input at both ends - LED Strip Lights Application Guide

4. The effect of working voltage on the brightness

Constant voltage light strips, the same number of LEDs, the same circuit scheme, using the same LED Chips, using the same resistance, if the length of the led strip is longer, the 24V led strip is brighter than the 12V led strip. This because of the higher the voltage, the smaller the voltage drop, as shown in the figure below.

The voltage at the end of the 24V led strip is 22V, and the voltage applied to each LED is 2.8V, while the voltage at the end of the 12V LED strip is 10V, and the voltage applied to each LED is 2.5V. You should know that the rated Vf value of the LED is 3V, obviously, 2.8V is closer to the 3.0V rated Vf value, so the brighter the light strip.

5. Influence of constant current IC chip on the brightness

Due to the internal resistance of the PCB board of the light strip, the constant current led strip also has a voltage drop, but the circuit scheme used by the constant current strip is different from that of the constant voltage light strip.

The figure below shows the circuit schematic diagram of the constant voltage led strip.

constant voltage led strip circuit - LED Strip Lights Application Guide

The figure below shows the schematic diagram of the constant current led strip.

constant current led strip circuit - LED Strip Lights Application Guide

There is one IC chip in each group of LEDs in the constant current Light strip. The LED will be connected in parallel with an IC chip, and to dynamically adjust the voltage applied to it. So that the LEDs of the entire group work at the rated voltage. This will keep the consistent brightness of the entire LED strip.

6. The effect of light-emitting chip size on the brightness

a. The same type of lamp beads has different sizes of LED light-emitting chips, this will resulting in different LED brightness.

LED STRIP light emitting chip - LED Strip Lights Application Guide

The difference between high-brightness and normal-brightness of the LED is caused by the different sizes of the light-emit chip used in the LED.

For example, the 5050 LED has 18-20lm, 20-22lm, 22-24lm, 24-26lm, and so on.

b. Different LED types have different brightness.

For example, the brightness of a single LED of 5050 or 2835 is basically around 20-24lm, while the brightness of 5630 LED can reach 45-55lm. This because the led chip used by 5630 LED is bigger than the chip used by other LEDs.

2835 and 5630 led chip compare - LED Strip Lights Application Guide

Of course, compared with other models of the same LED type, the larger the chip, the higher the brightness and the higher the price.

7. The effect of lamp bead density on the brightness

Use the same type of LED, if the brightness is not enough, you can increase the brightness by increasing the density of the LEDs.

For example, the led strip type of the 3528-120 LEDs/m will be much brighter than the type of the 3528-60 LEDs/m, and 5050-30 LEDs/m will be much darker than 5050-60 LEDs/m.

5. The LED density and power consumption of LED Strip Lights

We know that with the same type of LED, increasing the number of LEDs per meter can increase the brightness of the led strip light. Of course, this also increases the power of the light strip.

Therefore, the greater the density of LED strips with the same circuit structure, the greater the power.

Normally, led strip lights’s LED number is 30leds / m, 60leds / m, 90leds / m, 120leds / m, 240leds / m.

So, is it that the greater the power, the brighter the light strip?

A key parameter needs to be introduced here: Light efficiency.

led strip lights Light efficiency - LED Strip Lights Application Guide

Light efficiency is a parameter that characterizes the photoelectric conversion efficiency of a lamp. It refers to the brightness of led light that can be emitted per watt of power. The unit is lm / w. The larger the value, the higher the photoelectric conversion efficiency, and the more energy-efficient it is.

For example, there are two factories that produce the same 2835-120leds/m led light strip. We mark the light strip produced in factory one as the No. 1 light strip, and the second plant marked as the No. 2 light strip.

The No. 1 light strip

9.22w led strip lights - LED Strip Lights Application Guide

The No. 2 light strip

11.38w led strip lights - LED Strip Lights Application Guide

Through the integrating sphere test report, we can see that the brightness of the No.1 is better than the No.2 light strips, but the power of the No.1 light strip is 9.22w, it’s low more than the No.2. What happened?

The No. 2 light strip is much power than the No. 1 light strip, so it consumes more energy. As can be seen from the test report, the light effect of the No. 2 light strip is 92.43lm / w, and the No. 1 light strip is 141.01lm / w.

Therefore, it is unreasonable to judge the brightness of the light strip simply from the power level, and we must pay attention to the Light efficiency of the light strip, so as to achieve the purpose of using led lights to save energy.

6. The color temperature of the led strip light

1. Common colors have these: warm white light, the color temperature range is about 2100K-3000K. Natural white, the color temperature range is about 4000-5000K; positive white light (the color of noon sunlight), the color temperature range is about 5000K-6000K, cold white light, the color will close to blue, and the color temperature is above 6000K.

led strip colors - LED Strip Lights Application Guide

Because the color temperature corresponding to the above terms is an interval, the span of this interval is relatively large. If the led strip factory produces the light strip according to this standard, the led strip light color will be seriously inconsistent.

Therefore, an international strict regulation that the color temperature of a qualified light source must be controlled within 7 steps.

The Color Tolerance of LED Strip Lights – This article introduces in detail all the knowledge about the color tolerance of LED lights.

Usually, when we buy a light strip, we will not only tell the supplier that I want white or warm white light strips but also explain that the white color temperature is 4000K and the warm white temperature is 3000K. So that let the factory understand what led strip lights you need.

2. Choice the color temperature
Generally speaking, people in an environment with a high color temperature above 5000K are more likely to be excited, concentrate, engaged in delicate work, and also more prone to fatigue.

3000K low color temperature will be more relaxed and more secure, while moderate natural light with a color temperature of around 4000K can better reflect the color of the object itself.

So choosing which color temperature light we use depends not only on personal preference but also on the layout of the user environment.

7. The power classification of led strip lights

1. Power supply for low-voltage strip lights

According to the appearance characteristics, the power supply mainly divided into three types: desktop power supply, aluminum shell power supply, and waterproof power supply.

led strip lights power supply - LED Strip Lights Application Guide

The desktop power supply is very similar to the laptop’s external power supply, the only difference is the output voltage.

The aluminum shell power supply has more DC output terminals, which can connect more led strips in parallel to facilitate wiring. It is mainly used in permanently fixed and centralized power supply places.

The waterproof power supply is mainly used in a rainy or humid environment.

2. Power supply for high-voltage led strip lights

There are two types of power cords for the high-voltage light strips: the simple version and the customized version.

led strip lights power cord - LED Strip Lights Application Guide

Before leaving the factory, there will be equipped with a simple version power cord to every led strip light.

high voltage led strip lights power cord - LED Strip Lights Application Guide

After the user gets the strip lights, plug the power cord directly into the AC socket and the light will be working Light up.

The customized version power cord will be better than the simple version, and there will be no stroboscopic problems with the lighted light strip.

8. Dimming and color control of LED strip lights

All low-voltage monochromatic light strips support dimming. There are two main dimming methods for the light strips: dimmable power supply dimming and low-voltage dimmer dimming.

Dimmable power supply dimming requires the use of AC wall control dimmer and dimmable power supply.

The main dimming methods of dimmable power supply are TRIAC Dimming / DALI Dimming / 0 / 1-10V Dimming / ZigBee Dimming.

The wiring diagram is as follows

The wiring diagram of led strip lights - LED Strip Lights Application Guide

For low-voltage dimmer dimming, a DC dimmer is needed. The dimmer needs DC12V or DC24V power supply, and then connect the positive and negative poles of the led strip to the positive and negative poles of the dimmer output end.

The wiring diagram is as follows

9. The heats dissipation device of the LED strip light

Aluminum profiles, as accessories for led strips, have pushed linear lighting applications to a new level.

Aluminum profiles for led strip lights - LED Strip Lights Application Guide

The application of led strips is no longer limited to the field of auxiliary lighting or decorative lighting. More main lighting products are coming one after another.

For example, the following main lighting products have been widely praised by customers once they are put on the market. The emergence of aluminum grooves makes LED light strips more popular in the field of linear lighting.
