COB RGB LED strip Features：

1.) RGB COB LED light strips utilize "chip-on-board" technology, encapsulating micro-LED chips directly onto the strip's substrate and coating it with a uniform layer of fluorescent adhesive. As a result, they emit a continuous, perfectly uniform strip of light, completely free of graininess. This creates a very soft, high-end visual effect.

2.) Because their emitting surface is continuous, the red, green, and blue light is fully mixed upon emission. This results in incredibly smooth and uniform color transitions, enabling a pure, rich, and expressive color blend.

3.) RGB COB light strips typically have a beam angle of up to 180 degrees. This means their light spreads more widely, illuminating larger areas in applications like wall washing and ceiling troffer lighting. There are no noticeable dark areas when viewed from the side, resulting in a richer light effect.

4.) RGB COB light strips are extremely flexible and can be easily bent and folded, even with a tight bend radius, making them ideal for installation around complex shapes and corners. The back of the LED strip typically comes with high-quality 3M adhesive, making installation quick and easy.

5.) COB technology connects the chip directly to the substrate, shortening the heat dissipation path. This improved heat dissipation means the LED chip operates at a lower temperature, effectively slowing down light decay and extending the lifespan of the entire strip.

6.) Like SMD RGB LED strips, RGB COB strips also feature cutting marks at specific intervals, allowing them to be cut to the desired length, providing great flexibility.

RGB COB LED Strip VS  RGB SMD LED Strip

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:

COB RGB LED strip product details:

Easton Technology's RGB COB LED strips, with their core advantages of uniform, particle-free light, smooth color blending, and high visual quality, are widely used, primarily in decorative and ambient lighting applications requiring high light quality. These applications include:
1. Home Decorative Lighting (Pursuing a High-Quality Lifestyle)
This is the primary and most common application for RGB COB strips, aiming to enhance home style and comfort.

Ceiling Lighting

Ceiling Troughs (Indirect Lighting): Used in ceiling troughs in living rooms, bedrooms, and hallways. Light reflects off the ceiling, creating a soft, uniform halo, achieving a "light without lamp" effect, significantly enhancing the sense of depth and luxury in a space. COB uniformity is crucial here, eliminating the graininess often associated with standard strip lighting.

Curtain Box Lighting: Install strips in the recess above curtains, illuminating the curtains and creating a warm, romantic atmosphere while also highlighting the window area.

Background Wall and Wall Lighting

TV/Sofa Background Walls: Install RGB COB strips on the decorative shelves, grilles, or edges of the background wall. Uniform light perfectly outlines the wall and changes color to suit your mood or movie scene, becoming the visual centerpiece of your home.

Wall Washer Lighting: Install the light strip in a recessed groove at the top of the wall. The light evenly washes down the wall like water. The wide beam angle and uniformity of the COB light strip ensure consistent brightness across the wall, eliminating any unsightly flares.

Cabinet and Furniture Lighting

Under Kitchen Cabinets: As auxiliary lighting for countertops, the uniform, soft light eliminates shadows, making chopping and preparing food safer. It also creates a stylish, technological feel in the kitchen.

Inside Wardrobes/Display Cabinets: Open the cabinet door and the even light instantly illuminates clothing or collectibles, reminiscent of a high-end shopping mall display case, making it easy to access and creating a sense of formality.

Under Beds/Tatami: Installed at the base of the bed frame, it serves as a cozy night light and creates a sense of suspended technology.

Other Areas

Staircase Lighting: Installed along the edges or under the stair treads, it provides safety lighting while creating a smooth flow of movement, creating a beautiful and practical look.

Around Mirror Cabinets: Used on the back or sides of bathroom mirrors, it provides even facial illumination, avoiding shadows and is ideal for applying makeup and skincare.

II. Commercial and Public Space Lighting (Brand Enhancement)
In the commercial sector, lighting is a key tool in shaping the atmosphere of a space and attracting customers.

Retail and Display

Display Cases/Racks: Used for counter lighting of jewelry, watches, cosmetics, high-end electronics, and other products. The uniform light provided by COB strips perfectly showcases the quality and details of the products, enhancing their value.
