SPI WS2814 RGBW COB LED strip

Product Description:

The SPI WS2814 RGBW COB LED strip is an addressable RGBW continuous-light strip with an independent control chip. It combines three key technical features:
1.) WS2814 intelligent control chip
2.) COB (Chip on Board) continuous-lighting process: the chip is directly attached to the PCB and then coated with phosphor adhesive, creating a particle-free, continuous-light effect.
3.) RGBW four-color output (including an independent white light channel): red (R) + green (G) + blue (B) + white (W). This provides an additional independent white light channel compared to standard RGB strips, enabling a more natural neutral white or mixed light.

Easton Technology Co., Ltd.'s COB RGB  LED Strip products include 840leds/m. These products are available in 24V specifications. They can also provide multiple protection levels such as IP20/IP65/IP67/IP68, and can be used in different application scenarios. Easton Technology can also provide power supplies, controllers, aluminum profiles and other related accessories. In addition, Easton Technology also provides customized services, including wire length, PCB width, LED QTY, connector specifications, logo, packaging, LED light strip length, etc.

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

The differences between COB led strip products and SMT LED strip products of Easton Technology Co., Ltd. are as follows:

Key Points for Purchasing and Using SPI WS2814 RGBW COB LED Strips:

Applications: Thanks to its seamless light pattern, it's ideal for applications requiring high-quality, uniform illumination, such as cabinet lighting, display case lighting, interior contouring, wall lighting, and commercial spaces requiring creative lighting.

Purchasing Considerations:

Confirm the IP rating: The most common WS2814 COB strips are IP20 rated, meaning they're not waterproof and are primarily designed for use in dry, indoor environments. If you plan to use them in humid or outdoor environments, look for products with a higher IP rating (such as IP65/IP67).

Compatible Controller: You'll need a dedicated controller compatible with the WS2814 protocol and SPI signals to fully utilize its programmable addressing capabilities.

Compatible Power Supply: Because it operates on a 12V/24V power supply and draws a high power draw, ensure you have a sufficient 12V/24V DC power supply for the planned strip length and ensure safe wiring.

SPI WS2814 RGBW COB LED Strip Applications

1. )High-end Commercial and Product Display Lighting

Museums, Art Galleries, and Galleries: Utilizing their high color rendering index (typically CRI >90) and uniform light, COB strips accurately reproduce the true colors of artworks and artifacts, minimize glare, and create a solemn and professional exhibition atmosphere.

Luxury Stores, Cosmetics Counters, and Clothing Stores: Uniform light perfectly showcases the texture and color of merchandise. Independent white light can be used for basic lighting, while dynamic colored light creates eye-catching window displays and focal points, enhancing brand image.

Commercial Windows and Showrooms: SPI programming enables the creation of complex dynamic light shows, such as flowing colors and flashing in sync with music, greatly enhancing visual impact and appeal.

2. )High-quality Home and Interior Decorative Lighting

No-Main Light Design and Atmosphere Creation: Installed in living room ceilings, TV walls, bedside tables, or baseboards in bedrooms, COB strips' uniform light output creates a comfortable, glare-free indirect lighting environment, effectively enhancing the sense of luxury and comfort in a home. Kitchen and Functional Area Lighting: Installed under cabinets, this light provides supplemental countertop lighting. Its high-color-rendering white light makes food colors appear more realistic, ensuring safer chopping. It can also be used as a decorative accent in bookcases and alcoves.

Smart Home Scenario Linkage: You can program the lighting to work with your home's smart system. For example, it can automatically adjust to a soft blue light in movie mode, brighten to a warm white light when meeting guests, and simulate the gradual effect of morning light when waking up.

3.) Creative Design and Architectural Outlining

Indoor and Outdoor Architectural Outlining: Because the light strips are narrow (typically 10mm or 12mm) and flexible, they are ideal for concealed installation. They can be used to outline ceiling lines, door frames, stair railings, or building facades, achieving a clean, modern design style.

Furniture and Creative Installations: They can be embedded into custom furniture, such as bookshelves, bar counters, and table edges, making the furniture itself a light source, creating a futuristic and artistic visual piece. 4. Professional Entertainment and Atmosphere Creation

Home Theaters: Through SPI control, background lighting can be synchronized with the movie screen, greatly enhancing the sense of immersion.

Bars, Cafés, Restaurants, and Hotel Lobbies: Utilizing rich colors and dynamic effects, a diverse atmosphere can be easily created, ranging from exciting and dynamic to tranquil and romantic, adapting to the needs of different time periods and events.

Stage Designs and Wedding Banquets: As background lighting strips on stages or decorative moldings at banquets, these strips can be programmed to create a variety of dynamic lighting effects that match the theme, effectively adjusting the atmosphere.

Notes on Using the SPI WS2814 RGBW COB LED Strip:

1.) Control System: This strip requires a dedicated controller that supports the SPI protocol (such as certain FPGA or MCU solutions). Not all common LED controllers are compatible. You will need advanced programming and debugging skills to realize its full potential.

2.) Power Supply Requirements: This strip is powered by 12V/24V and requires a 12V/24V power supply. For long-distance installations, calculate the total power consumption based on the total length and power consumption, and consider multiple power points to prevent voltage drops at the end that could cause dimming.

3.) Installation Details: The LEDs have minimum cutouts (usually a few dozen LEDs or a few centimeters), so be mindful when cutting. Although the back of the LEDs has adhesive, ensure the surface is clean before installation. For special surfaces, we recommend using clips or glue to secure the LEDs.
