What is COB?
COB, or Chip on Board, is a pivotal term within the LED landscape, particularly when it comes to the world of LED strip lights. This technology represents a direct evolution in LED construction by embedding the LED chip directly onto the circuit board (PCB), a process sometimes colloquially known as a "flip-chip." The concept of flip-chip LEDs takes a streamlined approach to LED composition. Unlike the traditional Surface Mount Device (SMD) LEDs, which involve packaging the LED chip within a bead holder and a phosphor coating, the COB LED strip dispenses with extraneous elements, retaining only the LED chip, the yellow phosphor cover layer, and the connection pads. This architectural minimalism enhances the efficiency and illumination capabilities of COB LED strip lights.
By focusing on a leaner design, COB LED strips offer advanced luminosity and performance benefits. This technology's direct chip-on-board construction optimizes light output and thermal management, leading to superior brightness and durability.
What is COB LED Strip lights?
COB LED strip lights, also known as COB LED tape lights, are a revolutionary form of illumination where LED chips are directly affixed to a Flexible Printed Circuit Board (FPCB). This setup results in a seamless and dotless light strip, often referred to as a continuous or dotless LED strip light. The distinctive "COB" in COB LED strip stands for Chip On Board, signifying that multiple LED chips are integrated onto the strip. These LEDs are typically grouped together and coated with yellow phosphor, offering a uniform glow without the visible divisions seen in traditional light sources.
Key Features of COB LED Strip Lights
A COB LED strip shares similarities with conventional LED strips but boasts a pivotal distinction – it comprises multiple smaller LED chips. These chips, assembled closely, are embedded onto the circuit board itself. A layer of phosphor gel covers these closely aligned diodes, resulting in a continuous and seamless luminous effect. This innovative design also lends itself to tunable CCT and RGB color technologies, allowing users to effortlessly modify the color temperature and RGB color of their lighting through remotes or apps. Another advantage of COB LED strips is their remarkable flexibility; the compact diodes and close placement enable them to bend and conform to diverse shapes and spaces, accommodating tight corners and curvatures.
COB Continuous LED Tape: Ideal for Professional Installations
COB stands for Chip on Board, indicating that the LED diodes are directly integrated into the printed circuit board. One of the most notable benefits of this technology is its ability to eliminate visible spotting, even when utilized in shallower LED profiles and compact spaces.

How is COB LED strip lights manufactured?
Cob LED strip lights, also known as Chip-on-Board LED strip lights, are meticulously manufactured through a series of advanced processes to ensure their quality and performance. The production journey begins with the expansion of LED chips, followed by the precise die bonding process to affix these chips onto the Flexible Printed Circuit Board (FPCB). To regulate the electrical flow, resistors are skillfully added to the FPCB. The assembly then undergoes a high-temperature reflow process, where temperatures exceeding 65 degrees Celsius solidify the arrangement of chips and resistors on the PCB. The next step involves the integration of fluorescent powder glue, a critical component for light emission. An automated glue machine carefully dispenses the mixture onto the chip and resistor surfaces. After this, the glued COB LED strip enters an oven for curing. To ensure quality, rigorous quality checks are conducted post-cooling. Subsequently, the PCB is soldered into reels of up to 5 meters or tailored to customer preferences. Thorough testing, including an aging test and final QC assessment, takes place before the strips are meticulously packaged and readied for shipping. This intricate process guarantees the production of high-quality COB LED strip lights that find application in various lighting solutions.

FAQ
A COB LED strip and an SMD LED strip differ in chip arrangement and light intensity. In an SMD strip, chips are spaced on the circuit board. COB has chips closer for higher brightness. COB is brighter than SMD.
COB LEDs and regular SMD LEDs both have their advantages based on the lighting needs. COB LEDs are great for spreading light evenly over large areas, while SMD LEDs are better for focused tasks. Both types are efficient, durable, and long-lasting. COB for wide light, SMD for tasks.
LED stands for Light Emitting Diode, and it’s a type of light source. There are two main types of LED lights: LED panels and COB lights. Let’s understand the difference between them.
An LED panel is like a collection of small lights all together. It’s made using SMD LEDs, which are small lights that are mounted on a surface. These panels have fewer small lights, called diodes, and the way they’re connected is a bit complicated.
On the other hand, COB stands for Chip On Board. In a COB light, there are more diodes, but they’re arranged in a simpler way. The circuit design is less complex, which makes the light more compact. COB lights are brighter because of the many diodes packed closely.
So, to put it simply, LED panels have fewer but more complexly connected diodes, while COB lights have more diodes arranged in a simpler pattern. This makes COB lights brighter and more compact.
The main drawback of COB (Chip on Board) LED lights is their inability to create color-changing effects, unlike SMD (Surface Mounted Device) LED lights. This limitation arises from COB lights having only two contacts and a single circuit. This means that they cannot produce a wide range of colors or dynamic color changes like SMD LEDs can. If you’re looking for versatile lighting with color variation, COB lights might not be the best choice.
Pros:
Compact Design: COB LEDs have smaller LED beads packed closely together, leading to a more compact design. This helps in creating brighter and more efficient lighting solutions.
Enhanced Protection: These LEDs offer improved protection against moisture, dust, and physical damage due to their sealed construction.
Longevity: COB LEDs tend to have a longer service life compared to traditional LEDs, resulting in reduced replacement and maintenance costs.
Low Dead Light Rate: They have a lower dead light rate, which means fewer individual LEDs within the array fail, maintaining consistent brightness over time.
Cons:
Manufacturing Complexity: The manufacturing process of COB LEDs can be more complex, involving intricate assembly techniques. This complexity might lead to higher production costs.
Maintenance Challenges: If an individual LED within the COB array fails, it can be challenging to replace just that one LED. This could necessitate the replacement of the entire COB unit, increasing maintenance efforts.
In summary, COB LEDs offer benefits such as compactness, durability, and energy efficiency. However, their manufacturing intricacy and potential maintenance difficulties are important aspects to consider when choosing lighting solutions.
