COB RGBW LED strip Features：

1.) COB technology packages tiny RGBW chips directly onto a circuit board at a high density, then coats them with a uniform layer of fluorescent adhesive. When lit, this creates a continuous, uniform light strip, completely eliminating the graininess or spotting often seen with traditional discrete LED strips. This is its most intuitive and core advantage, resulting in a very high-end, soft visual effect.

2.) RGBW Four-in-One Chip: This integrates red, green, and blue primary color chips, along with a separate white chip. The RGB portion: Mixing light creates a myriad of vibrant, saturated colors. The separate white (W) portion: This is crucial! It provides high-quality, pure white light with high color rendering, independent of RGB color mixing. This means you can enjoy vibrant colors while also getting comfortable, neutral white light for everyday lighting.

3.) White light mode: Typically boasting a color rendering index exceeding 90, this mode faithfully reproduces the natural colors of objects, making furniture, decorations, and food appear more vibrant and lifelike. It is often used in museums, galleries, high-end retail, and home kitchens, where color fidelity is paramount. 4.) The COB packaging structure allows for a larger heat dissipation area and shorter heat dissipation paths for the chip. This effectively reduces light decay, resulting in a theoretical lifespan of typically over 50,000 hours. Its stability and reliability far surpass those of SMD LED strips.

5.) Traditional SMD LED strips have a beam angle of approximately 120°, while COB strips typically reach a beam angle of 180°. This results in a wider light spread and a larger illumination area, creating a very uniform, blind-angle-free light curtain.

6.) COB RGBW LED strips retain the fundamental characteristics of SMD LED strips: they are flexible and bendable, and can be cut at designated cutting points to accommodate different installation lengths.

7.) COB RGBW strips typically require a controller, which imbues them with powerful intelligent features. Dimming, color temperature adjustment (if the W is dual-color temperature), color change, and dynamic scene settings can be controlled via an app, remote control, or even voice commands, making them easily integrated into smart home systems.

 COB RGBW LED Strip VS SMD RGBW 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:

Considerations for purchasing COB RGBW LED strip:

1.) Confirm the control method: Before purchasing, consider how you'll control it. Will it require a simple remote control, or will it require control via a mobile app or smart home platform? Make sure the strip you choose is compatible with the corresponding controller.

2.) Pay attention to color variability: COB strips may vary slightly from batch to batch. If you plan to use them in multiple locations, it's recommended to purchase a sufficient quantity at once to ensure consistent color.

3.) Calculate the power supply: The power supply should exceed the total power consumption of the strip, with a margin of approximately 20%. For example, if you're using a 5-meter strip with a power rating of 19W/meter, the total power consumption is 95W, so it's best to choose a power supply with a power rating of 120W or higher.

4.) Consider the installation environment: If using the strip in a humid environment like a bathroom or kitchen, or outdoors, be sure to choose a model with an appropriate waterproof rating, such as IP65 or IP67.

COB RGBW LED Strip Installation and Use:

 1.) Clean Surface: Before installation, ensure the surface to be attached is clean, dry, and free of oil and dirt to ensure a secure adhesive bond.

 2.) Proper Cutting: The strip can be cut at designated cutting points to fit your installation length.

 3.) Connection Care: When connecting multiple strips or connecting to a controller, ensure that the positive and negative poles are aligned correctly: "+" for "+" and "-" for "-".

COB RGBW LED Strip Maintenance and FAQs:

 1.) Daily Maintenance: Gently wipe the strip surface regularly with a dry, soft cloth. Avoid using chemical solvents or scratching with hard objects.

 2.) Troubleshooting: If the strip does not light up, first check the power connection and that the controller is turned on. If a section does not light up, check for loose connectors or damage to the section.
