COB LED Strips 101: A beginner’s Guide for Seamless Lighting

COB LED strip uses innovative “Chip on Board” technology, where LED chips are directly connected to the flexible printed circuit board (FPCB) without the need for gold wire encapsulation, unlike traditional SMD LEDs. This design greatly enhances the reliability of the strip, as the gold wire is a common potential failure point in traditional LED strips.

The PCB design of COB strips are different from traditional SMD LED Strips’. It adopt a unique method: three chips are first connected in parallel to form a group, and these groups are then connected in series to create a continuous strip. This configuration ensures that even if one or two chips in a group fail, the rest of the strip remains lit, significantly improving the overall reliability and lifespan of the LED strip light.

COB LED light strips feature a very high chip density, with up to 480 chips and more per meter. This high-density design not only ensures uniform light output but also enhances the overall performance and reliability of the strip. Even if individual chips fail, they do not significantly affect the overall effect of the light strip.

Chip on board LED strip typically has stronger anti-static capabilities, which is especially important in dry climates or certain seasons. Additionally, many COB LED strip lights are designed with corrosion-resistant materials, effectively resisting the sulfidation process and extending the lifespan of the LED strip in harsh environments.

COB LED Strip Lights could produce smooth and continuous light due to the high density of LED chips. This feature is particularly useful for applications where uniform light output is crucial, such as under-cabinet lighting, cove lighting, or any setting where the light source is visible. The seamless illumination of COB LED Strip eliminates the spotting inherent in other types of LED lighting, enhancing the aesthetic appeal of the space.

Despite the COB LED Strip’s high brightness and high density, its advanced technology enables it to save more energy compared to traditional lighting solutions. This high energy efficiency not only reduces operational costs but also meets the modern demand for eco-friendly, energy-saving options. High quality COB LED strip lights can achieve a light efficacy of more than 100 Lm/W. This combination of durability and low energy consumption makes Chip on board LED strips a cost-effective and sustainable lighting choice.

COB LED strips offer High color rendering, with a CRI (Color Rendering Index) often exceeding CRI 90. This means they can more accurately reproduce the true colors of objects. High color rendering is particularly important in certain applications, such as exhibitions, commercial displays, art galleries, and professional photography studios. By presenting colors more authentically, High CRI COB LED strip not only improves lighting quality but also provides greater opportunities for creating specific atmospheres and highlighting product features.

Another prominent advantage of COB LED strip is its high light density and High brightness. Each meter of COB strip can accommodate up to 480 LED chips and above. Such high density arrangement not only increases the brightness output per unit length but also ensures that even if individual chips fail, it does not significantly affect the overall performance of the strip. The high density makes Chip on Board LED strip an ideal choice for applications requiring high brightness, such as kitchen countertop lighting, cove lighting, or step lighting in indoor environments.

High Flexibility is a unique feature of Chip on Board LED Strips. The bending of the PCB will not damage the encapsulated LED chips. Therefore, COB LED makes it convenient to create curved LED screens, circular screens, and wavy screens. This makes them an ideal substrate for customized shaped screens in bars and nightclubs.

Chip on Board LED strips typically offer a wide beam angle of 180 degrees, ensuring that light is distributed broadly and evenly. This wide beam angle effectively reduces shadows and dark spots, creating a warmer and well-lit environment. This characteristic makes the COB LED strip particularly suitable for applications requiring uniform illumination, such as display cases, bookshelves, or artwork lighting.

The superior heat dissipation performance of COB technology is another significant advantage. Since the LED chips are directly mounted on the substrate, heat can be more effectively dissipated, which not only improves the strip’s efficiency but also extends its lifespan. Effective heat management allows the COB LED Light Strip to operate stably at higher brightness levels for extended periods without encountering overheating issues.

One significant disadvantage of COB LED strips is the difficulty in maintaining color consistency across different batches, as they do not undergo the binning process commonly used in LED manufacturing. This lack of binning can result in slight variations in color temperature and hue, which become noticeable when integrating new segments into existing setups.

However, with technology development, our COB LED Strip Series maintains an SDCM (Standard Deviation of Color Matching) of less than 3 to ensure color consistency and avoid this issue.

Compared to some high-power SMD LED strips, COB LED strips may have lower light efficiency. Our high quality COB LED strips can reach up to 140Lm/W, but they do not achieve the 190Lm/W same as our 2835 LED strip Series. They often produce less light per watt of energy consumed, which can be a drawback for applications requiring high light output. However, many users find that the superior light quality and uniformity provided by the COB LED strip outweigh this limitation.

The production of High quality COB LED Light strips is generally more expensive than traditional SMD LED Light strips. This is due to the precise manufacturing processes and additional materials required for it. As a result, COB LED strip lights tend to be less accessible for budget-sensitive projects, limiting their market potential compared to lower-cost alternatives
