What is the Size of COB Modules?
As a prominent supplier in the COB (Chip-on-Board) Modules industry, I often encounter inquiries regarding the size specifications of our COB modules. The dimensions of COB modules can vary significantly based on a multitude of factors, and understanding these variations is crucial for both new and seasoned users in determining the suitability of a module for their specific applications.

Factors Influencing the Size of COB Modules
The size of a COB module is primarily dictated by the intended application. For instance, in the field of general lighting, COB modules are commonly used in downlights, spotlights, and track lights. These lighting fixtures typically require smaller-sized COB modules to fit within the compact housing. The compact size allows for greater flexibility in fixture design and installation. On the other hand, large-scale industrial lighting or outdoor lighting applications may demand larger COB modules to achieve higher luminous flux and better illumination over a wider area.
Another significant factor is the number of chips integrated into the COB module. A COB module is essentially a cluster of LED chips bonded directly onto a substrate. When more chips are incorporated, the module will naturally have a larger footprint. The number of chips is directly related to the module’s light output, color temperature, and color rendering index (CRI). For applications that require high-intensity and high-quality lighting, such as in photography studios or art galleries, COB modules with a larger number of chips and thus a larger size are often preferred.
The manufacturing process also plays a role in determining the size of COB modules. Advanced manufacturing techniques allow for more precise placement of chips and better utilization of the substrate space. This can result in smaller-sized modules with the same or even better performance compared to those produced using traditional methods. Additionally, the choice of substrate material affects the module’s size. Some substrates have better thermal conductivity, which can help dissipate heat more efficiently. This allows for the design of smaller modules as less space is required for heat dissipation components.
Common Size Ranges of COB Modules
In the market, COB modules come in a wide range of sizes. For small-scale lighting applications, such as decorative lighting or indicator lights, the diameter of COB modules can be as small as 3 – 5 mm. These tiny modules are ideal for applications where space is extremely limited and a low level of illumination is sufficient.
In the residential and commercial lighting sectors, COB modules with diameters ranging from 10 – 30 mm are very popular. These mid – sized modules can provide a good balance between light output and size. They are commonly used in downlights, where a compact size is required to fit into ceiling fixtures while still delivering adequate illumination to the room.
For large – scale lighting applications, COB modules with diameters greater than 30 mm are available. Some industrial – grade COB modules can have diameters of up to 50 mm or even larger. These large modules are designed to produce a high luminous flux, making them suitable for lighting large warehouses, sports stadiums, and outdoor parking lots.
Custom – sized COB Modules
One of the advantages of being a COB module supplier is the ability to offer custom – sized modules. Many customers have unique requirements that cannot be met by standard – sized modules. For example, in some architectural lighting projects, the lighting fixtures are designed with specific dimensions, and the COB modules need to be customized to fit perfectly.
Our company has a team of experienced engineers who can work closely with customers to design and manufacture custom – sized COB modules. We first understand the customer’s application requirements, including the desired light output, color temperature, and installation space. Based on this information, we can optimize the chip arrangement and substrate design to create a module that meets the exact size and performance specifications.
Custom – sized COB modules also provide flexibility in terms of design innovation. Customers can explore new lighting concepts and create unique lighting solutions that stand out in the market. Whether it’s a complex-shaped lighting fixture or a lighting system with specific beam angles, our custom – sized COB modules can help bring these ideas to life.
Importance of Correct Size Selection
Selecting the right size of COB module is of utmost importance. If the module is too small for the intended application, it may not provide sufficient light output, resulting in poor illumination. This can be a major drawback, especially in settings where proper lighting is crucial for safety, productivity, or visual enjoyment.
Conversely, using an oversized module can lead to inefficiencies. A larger module may consume more energy than necessary, increasing operating costs. It may also generate more heat, which can shorten the lifespan of the module and require additional heat dissipation measures.
Moreover, the size of the COB module impacts the overall aesthetics of the lighting fixture. An ill – fitting module can make the fixture look bulky or unbalanced. By choosing the correct size, designers can create lighting fixtures that are both functional and visually appealing.
How to Determine the Right Size
When determining the appropriate size of a COB module, customers should first consider the lighting requirements of the application. Calculate the required luminous flux based on the area to be illuminated and the desired illuminance level. This can provide a starting point for selecting a module with the right light output capacity.
Next, evaluate the available installation space. Consider the dimensions of the lighting fixture, including the height, width, and depth. Ensure that the selected COB module can fit comfortably within the fixture without any clearance issues.
It’s also advisable to consult with a professional lighting designer or a COB module supplier. We have extensive experience in the field and can offer valuable advice based on our knowledge of different applications and module capabilities. We can help customers analyze their specific needs and recommend the most suitable module size.
