Understanding COB LED Technology

COB LED, an acronym for "Chip On Board" LED, represents a remarkable stride in LED lighting innovation, outshining various other LED types with its unique advantages. Unlike traditional LEDs, COB LEDs boast an arrangement of LED chips meticulously arranged in proximity on a silicon carbide base. This configuration results in exceptionally uniform and intense illumination, making it a preferred choice not only for filmmakers but also for photographers seeking impeccable lighting conditions.

The distinguishing feature of COB technology lies in its incorporation of nine or more diodes, all operating within a single circuit supported by two contacts. This design, irrespective of the number of diodes, ensures consistent performance. Larger COB chips, capable of emitting up to 250 lumens, offer even brighter lighting output, granting a distinctive panel-like aspect. However, it's worth noting that COB LEDs are primarily designed for consistent lighting rather than color-changing effects due to their utilization of a singular circuit.

In a COB LED lighting system, the core component comprises numerous LED chips arranged in close proximity on a ceramic or metal surface. Emitting light photons as semiconductors, these LEDs collectively create a powerful illumination source. What sets COB technology apart is its ability to achieve high brightness levels while consuming significantly lower wattage. This innovation challenges the traditional notion that brightness and battery runtime are inversely proportional, presenting a more energy-efficient solution.

In comparison to the more common SMD LEDs, COB LEDs demonstrate an exceptional balance between brightness and energy consumption. While SMD LEDs are individual diodes packaged closely together, COB LEDs incorporate multiple chips within a singular unit, resulting in a concentrated light source. This advancement not only defies the conventional trade-off between brightness and battery life but also provides a more compact and efficient lighting solution.

In essence, COB LED technology represents a significant advancement in the world of illumination. Its ability to provide uniform and intense lighting through densely packed LED chips, coupled with its energy efficiency, positions it as a versatile choice across various applications, from professional filmmaking to everyday photography and beyond. As lighting technology continues to evolve, COB LEDs stand at the forefront, illuminating a brighter and more efficient path forward.

What Is SMD LED?

SMD LED, or Surface Mounted Device Light Emitting Diode, is a cutting-edge technology in the realm of LED lighting. These tiny wonders have transformed the way we illuminate spaces. SMD LEDs are manufactured using a technique where components are directly mounted onto circuit boards, eliminating the need for traditional pins and leads. This innovation has streamlined production, allowing automated assembly machinery to take the lead over human labor. Notably absent is the hemispherical epoxy casing found in other LEDs, which broadens the viewing angle and enhances the overall lighting experience.

These LEDs boast impressive efficiency, emitting bright and even illumination while consuming minimal wattage. One of their remarkable features is the integration of three primary colors within a single encapsulation, revolutionizing the quality of light output. The assembly of SMD LEDs involves a polarization process, demanding high-quality equipment and precision. This meticulous approach conquers issues that plagued earlier LED technologies, preventing non-functional LEDs and enhancing the reliability of lighting systems.

SMD technology, a true successor to its wire-leaded predecessor, is grounded in LED advancement. Departing from the past's wire leads, SMD technology thrives on mounting minute components, efficiently utilizing space—ideal for compact electronic devices. Beyond size, it revolutionizes the manufacturing process, enabling automated assembly of Printed Circuit Boards (PCBs). The ripple effect? Heightened device reliability, efficiency, and performance.

In a world where lighting requirements span from sleek LED strip profiles to versatile linear pendant lights, SMD LEDs have emerged as a cornerstone. These LEDs harmonize seamlessly with various lighting solutions, from versatile LED profile applications to efficient linear pendant lights, and even dynamic LED panel lights. They're a force to reckon with in the domains of ceiling lights, downlights, spotlights, floodlights, and high bay LED lights. Even track lighting and tube lights benefit from SMD LED's compact prowess.

Brightening Up the Future

In summary, SMD LED technology isn't merely about lighting up spaces; it's about igniting innovation. From its compact size and versatile compatibility with different lighting profiles to its automated assembly prowess, SMD LEDs have changed the game. With a focus on simplicity, these LEDs have transcended the technical jargon, making them accessible to everyone, from curious minds to elementary-level learners. As the UK and beyond embrace the future of lighting, SMD LEDs stand as a testament to progress, efficiency, and brilliance.

Key Differences Between COB LED and SMD LED

In the realm of LED lighting, understanding the disparities between COB LED and SMD LED is crucial in selecting the ideal lighting solution. These two LED types diverge in several essential aspects, guiding our preference for specific applications.

LED Type:

COB LED (Chip on Board) and SMD LED (Surface Mount Device) stand as the representatives of these technologies. COB integrates multiple LED chips on a single module, while SMD employs individual LEDs mounted onto a circuit board.

Brightness and Energy Efficiency:

COB LEDs shine brighter than SMD LEDs due to their unique design, offering approximately 80 lumens per watt compared to SMD's range of 50 to 100 lumens per watt. In terms of energy efficiency, COB emerges as the winner, with its high production efficiency making it an excellent choice for various lighting needs. Both COB and SMD LEDs outperform traditional filament bulbs in terms of energy efficiency.

Color and Color Temperature:

SMD LEDs outshine COB LEDs in terms of color versatility. SMD's use of RGB (Red, Green, Blue) primary colors allows for a broader color spectrum and adjustable color temperature. On the contrary, COB LEDs emit a single color, resulting in stable lighting. This trade-off between versatility and stability defines the choice between these two technologies.

Quality of Light:

COB and SMD LEDs offer varying qualities of light due to their differing diode arrangements. SMD's multiple diodes yield glare-prone light, suited for point lighting. COB technology, however, generates uniform and glare-free light, creating a wide-angle beam ideal for surface illumination.

Manufacturing Cost:

When considering manufacturing costs, COB LEDs have an edge over SMD LEDs. The production process of SMD LEDs involves higher costs due to factors like labor and materials. COB LEDs, with a simpler manufacturing process, prove more cost-effective.


The choice between COB and SMD LED depends on the application. SMD LEDs find favor in commercial spaces like restaurants, clubs, hotels, and retail shops due to their versatile color options. COB LEDs, with their powerful and wide-angle beams, excel in industrial and security settings.

In conclusion, the choice between COB and SMD LEDs boils down to specific lighting requirements. COB LEDs offer higher brightness and energy efficiency, making them optimal for industrial applications. Meanwhile, SMD LEDs provide greater color flexibility, catering to commercial spaces. Understanding these distinctions empowers us to make informed decisions when seeking the perfect lighting solution.
