COB RGB WS2811 Pixel LED strip

Product Description:

COB RGB WS2811 Pixel LED strip is an addressable COB (Chip on Board) strip with a built-in intelligent control chip. It combines traditional COB continuous light technology with pixel-level control chip technology (similar to the WS2811/WS2812 series) to achieve a variety of dynamic lighting effects.

COB RGB WS2811 Pixel  LED strip Features：

1. Providing uniform, soft light without graininess, the WS2811 RGB COB LED strip emits a continuous, uniform light strip, completely eliminating the individual LEDs and light spots of traditional LED strips. The visual effect is extremely comfortable, high-end, and glare-free, making it ideal for scenes requiring high-quality ambient lighting.

2. Fully addressable and independently programmable, the integrated WS2811 controller chip allows each LED group on the strip to be individually controlled. Through programming (using Arduino or Raspberry Pi), you can create any dynamic effect you can imagine, such as rainbow gradients, color chases, flowing lights, and rhythm synchronization, rather than relying on a single color for the entire strip.

3. Wide beam angle and wide illumination range. The COB package creates a continuous, flat surface instead of discrete points, resulting in a beam angle of 180 degrees or more. This allows for more comprehensive illumination of the mounting surface. In applications such as light troughs and background walls, the light is dispersed more evenly, eliminating noticeable light-dark boundaries. 4. Flexible and easy to install. Using a flexible FPC circuit board, it can be easily bent and folded, and typically features 3M adhesive backing. It can conform to various curved and irregular mounting surfaces, such as round pillars and artistic shapes, making installation very convenient.

5. Highly reliable and durable. COB technology directly packages the LED chips onto the board, eliminating the solder pins of traditional SMD lamp beads, resulting in a more robust structure. It is more resistant to vibration and impact, reducing the risk of physical damage and extending its service life.

The production process of COB led strip products of Easton Technology Co., Ltd. is:

1.) First coat the PCB pads with solder paste through an automatic solder paste machine. The coating uniformity and thickness of the solder paste determine the quality and flatness of the soldered chips, as well as the quality of the soldered chips; Apply solder paste

2.) Load the PCB board coated with solder paste on the carrier, input and set the die-bonding program of the chip through computer programming, adjust the direction and height of the die-bonding, and confirm the electrode direction of the chip;

3.) Do a small-batch die-bonding test first, and inspect the appearance quality of the solid-bonded PCB to determine the direction of the die-bonding, whether there is solder paste connected, and whether the position of the die-bonding is correct, and the inspected product will flow into the next process. ;

4.) Put the solid crystal PCB board and wafer into reflow soldering, set the temperature and speed of reflow soldering, solder the LED chip firmly in the reflow soldering, and conduct an electrical test after being released to test whether the LED chip emits normally. ;

5.) After testing the LED chip on the PCB board, carry out the powder mixing process of silica gel and phosphor powder, according to the photoelectric parameters such as color temperature and brightness specified by the customer, carry out different proportions of configuration, and carry out positive air defoaming of the prepared glue

6.) Fix the PCB board on the glue dispenser carrier for the glue dispensing process. The glue dispensing process is the most critical process for the success of the light strip. After dispensing, put the PCB board into the oven for baking. The glue from different manufacturers If the baking conditions are inconsistent, you must refer to the manufacturer's requirements for verification before setting the appropriate baking temperature.

7.) After the glue is dispensed, test the photoelectric parameters of the light strip to see if the test data meets the customer's requirements.

8.) After welding the 0.5-meter PCB board, connect it to the requirements ranging from 5-10 meters;

9.) Aging detection

10.) Pack the light strip with a reel after testing the adhesive;

11.) Check again after the reel, put it in an electrostatic bag, and pack it into a box

Notes on WS2811 COB RGB LED light strips:

1. Controller and programming knowledge are required. As a digitally addressable light strip, it cannot be directly connected to a regular power source. It must be connected to a smart controller (such as the ESP8266 or Arduino) to utilize its programmable features. Users must have a basic programming foundation or be willing to learn and use existing control software.

2. High power requirements, especially for long-distance, high-brightness, full-white light applications, require high current. A power adapter with sufficient power and voltage is essential. When used over long distances, it may be necessary to inject power from multiple points to prevent the LEDs at the end from dimming or discoloring due to voltage drops.

3. Heat management: COB light strips emit dense light and generate heat when running at high power. It is recommended that the light strips be affixed to aluminum profile slots. The aluminum slots not only provide a professional light output (like a lens), but more importantly, they also play a crucial role in heat dissipation, effectively extending the life of the light strip.

COB RGB WS2811 Pixel  LED strips have a wide range of applications. Their perfect combination of programmable dynamic effects and uniform, soft, high-quality lighting makes them an ideal choice for projects seeking an exceptional visual experience.
