How Are LED Strip Lights Manufactured?

LED STRIP SMT PROCESSLED lights are more and more used in our everyday life. They can be seen everywhere, such as indoor decorations, Christmas decorations,s and so on. They are replaced by traditional lamps gradually. But do you know how to make the led strip light in the factory? Although the LED is a kind of new product, the making process is still the same as other regular products. So how do we make the LED lights?

What is a LED Strip Light?

LED STRIP LIGHT SIZELED Strip Lights are a great way to add bright and colorful illumination to any project. They come in flexible strips and can be cut to fit any length. They can be cut with a sharp knife or scissors, but they're the best cut with a pair of scissors that have been heated up with a lighter or match. The heat helps soften the plastic making it easier to cut cleanly.

LED Strips come in many different sizes, colors, and shapes. Our LED Strips are available in 12-volt models (for use with our Power Supplies) or 24-volt models (for use with our 24V Power Supplies).

LED Strips are basically long lines of super-tiny LED's (Light Emitting Diodes) that emit light when current flows through them from an external power source such as one of our Power Supplies (either 12V DC or 24V AC).

The advantages of using LED strip lights over conventional light bulbs include:
Efficiency - LEDs use very little power so you can get more light for less money. In fact, for every watt of electricity used by an incandescent bulb, an equivalent LED will use only 1/10th of that wattage!

Where can we use the LED strip light?

Custom-Outdoor-Strip-LightingLED Strip Light is extremely versatile and can be used in many different applications. Some popular uses include:

Outdoor lighting – Whether you’re looking for decorative lighting or security lighting, LED Strip Lights are a great choice. They are waterproof and durable, so they will last for years without any maintenance required. They can also be installed anywhere outdoors without worrying about water damage or corrosion.

Indoor decorating – Use LED Strip Lights indoors to create unique designs that will draw attention to your home or business. You can use them in rooms like kitchens, bathrooms, bedrooms, and more! The possibilities are endless when it comes to indoor decorating with LED Strip Light!

LED Strip Lights Manufacturing Process

Step 1: SMD LED Production

smd-led-chipsThe first step in the manufacturing process is the production of SMD LEDs. These are small, surface-mounted devices that emit light when voltage is applied to them. The SMD LEDs are then mounted onto an aluminum substrate and encased in a transparent epoxy resin to protect them from damage during transportation.

Step 2: Solder Paste Printing

LED STRIP LIGHT Reflow-SolderingThe next step in the manufacturing process involves printing solder paste onto both sides of the PCB boards using a computer-controlled printer (screen printer). The solder paste helps to provide electrical connections between components on the PCBs and wires.

Step 3: Component Placement (SMT)

The SMDs are then placed on the respective pads on each side of the PCBs using automated machines known as pick-and-place machines. These machines do not require human assistance and can place hundreds of components per minute, giving manufacturers an efficient way of producing large numbers of LED strip lights without sacrificing quality or precision.

Step 4: Reflow Soldering

The next step involves reflow soldering all of the components together by applying heat until they melt into each other and form solid connections between PCB and LED.

Step 5: Soldering

The LEDs in an LED strip are soldered onto a PCB (Printed Circuit Board). This is done with special machines that heat up the surface of the board and then apply solder to it.

Step 6: Aging and Waterproofing

This step is important as it makes sure that your LED strip lights will last for a long time. It also ensures that they are waterproof, however, not all strips go through this step so make sure yours do!

Step 7: Tape Pasting and Packaging

Your LED strip lights will be packaged in boxes or wrapped in plastic depending on how they are being shipped out to customers or retailers.

Which factors affect the quality of led strip lights?

The quality of a led strip light is determined by the following factors:

Copper in PCB (Printed Circuit Board)

led-strip-light-single-side-pcb-vs-double-side-pcbThe copper in the PCB is an important part of the circuit design. It helps to transfer electricity from one place to another. If it is not done properly, then it will create problems with your circuit and you may end up with faulty lights.

Quality of CCT in LED (Color Changing Technology)

This refers to how well your led strip lights can change colors. In order to ensure that this happens properly, you need to check on how well-made they are and whether they have any issues with heat or electricity leakage. These things can cause problems with the quality of the product and ruin your experience completely.

Component Placement

The placement of each component matters a lot when it comes to manufacturing these lights. Each component needs to be placed at its right location so that it performs its function without any issues or problems while also making sure that there is no overloading or under loading happening at any point during use. This ensures that everything runs smoothly and there are no chances of failure during operation as well as after installation.

Component Quality

The quality of all components used for manufacturing these led strip lights is very important. LEDs are the most important component in these lights, as they determine how bright and efficient the light will be. In addition, there should be proper insulation between each LED bulb, so that they don’t overheat and burn out.

Silicone Covering

LEDs must be covered with silicone as this helps protect them from moisture and dust accumulation which can cause corrosion inside the device itself. The silicone covering should also prevent any electric shock or fire hazard due to accidental contact with live wires or water droplets falling on them during installation or use.

Heat Dissipation System

LEDs generate heat while they are working and this heat must be dissipated away from the device surface so it doesn’t cause damage or malfunctioning of electrical components inside it like transistors etc. This is done by using an aluminum heat sink that absorbs.


LED strip lights are an excellent alternative to other light sources available in the market. But it is smart to know how these are made? After knowing the manufacturing process, one can have a better idea of how these strip lights are made to shine brightly, and the right factor which affects the quality of these lamps.
