How Are LED Strip Lights Manufactured? - Lightstec

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)

The 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.

In this article, we will take a look at the production process of LED strip lights. We will start with a brief overview of the manufacturing process, then we will move on to a more detailed description of each step in the production process.

I attached a production flow chart to give you a general idea of the process.

Raw Materials be Put in Storage

After the raw materials arrive at our factory, they will be stored in our transit warehouse. After the raw materials are tested and passed, they will be transferred to our official raw material warehouse.

Raw Materials Inspection

Our raw material quality inspectors will conduct a complete inspection of the raw materials. If the raw material passes the inspection, it will be transferred to the official raw material warehouse, otherwise, it will be returned to the raw material supplier.

LED Dehumidification 

Before the LED lamp bead is used in production, it needs to be dehumidified, otherwise, the LED lamp bead will be damaged by moisture when the LED lamp bead is reflow soldering.

First Sample Confirmed  

Before mass production, we need to make a sample from raw materials. We will run various tests on this sample. Only if this sample passes these tests will this batch of raw material be used for mass order production.

Brush Tin on PCB, SMT 

We will brush solder paste on the PCB, and then attach the lamp beads, resistors, and other components to the PCB.

Reflow Soldering Through Furnace 

When the SMT is completed, the PCB with the lamp beads attached will be sent to reflow soldering. After reflow soldering, the lamp beads, resistors, and other components will be soldered to the PCB.

QC Inspection 

Our inspectors will inspect the appearance of the PCB and light up the LEDs to ensure that the LEDs, resistors, and other components are properly soldered to the PCB.

PCB Welding 

After SMT is completed, our PCB is 0.5 meters each. The regular length of our product is 5 meters, so we need to solder the PCB to make it into a 5-meter roll.

This step, for small orders, we will do it manually, otherwise, it will be done by machine.

Clean PCB and Test 

The soldering place of the PCB will be a little dirty, we need to clean the place where the PCB is soldered. Then we check and light up a 5-meter LED strip to make sure it&#;s working properly.

Paste 3M tape 

With competitive price and timely delivery, Joineonlux sincerely hope to be your supplier and partner.

In most cases, we will stick 3M double-sided tape on the back of the PCB. 

Reel Strip 

The LED strips are rolled onto a plastic reel. For non-waterproof LED strips, it is usually 5 meters rolled onto a plastic reel. If it is a waterproof product, it will be rolled onto a large reel, waiting to be transferred to the waterproofing treatment.

Waterproof Treatment

For waterproof LED strips, we use the most advanced silicone extrusion process.

Silicone integration extrusion is when the LED strip lights and solid silicone are extruded together through a mold and are shaped by high-temperature vulcanization.

Baking-Curing

After the LED strip light and the silicone are extruded together, they will pass through a high-temperature oven, and then the silicone will be cured by vulcanization.

For detailed information about silicone extrusion, please visit What is silicone integrated extrusion?

Laser Marking  

We will use a laser to mark the model, production date, CCT, Voltage, Wattage, and other information on the product.

Inspection of Appearance

Our quality inspectors will check the appearance of the products to ensure that the label information and appearance of the products are correct.

Power-on Test  

Our quality inspectors will light up each LED strip to ensure that they can work properly.

Finished Products Packed in Reel 

The finished LED strip is rolled onto a plastic reel, usually 5 meters per roll.

Packing 

Then each roll of LED strips will be packaged in an anti-static aluminum foil bag.

Paste Label 

A label is attached to the outside of each anti-static bag.

Put in Storage

These packaged LED strips will be stored in our warehouse, waiting to be shipped.

OQC Spot Check

Before the LED strips are shipped, our quality inspectors will also randomly check them for quality. Only LED strips that pass the OQC spot check will be sent.

Shipment

We will send the LED strips according to the customer&#;s shipping requirements (by express, air, or sea).

Conclusion

After reading this article, you should know about our LED strip production process. Because of this complete process, our lead time may be longer, but our product quality can be more stable.
