COBs (chip on board) and GU2PCBN (Global Uniform Power Converter Board-emitter) are two popular light engine applications in the LED lighting industry. Both have a significant role in providing a level of efficiency, performance, and cost savings that can make a big impact in the lighting industry. It is important to understand the differences between the two to determine what is most suitable for any particular application.

What is GU2PCBN?

GU2PCBN is an advanced chip-on-board (COB) design that uses a global uniform power conversion technology to provide a higher level of efficiency than traditional COBs. It utilizes a homogeneously spread out power conversion board that feeds a separate light engine in order to maximize the efficiency of the LED light fixture. GU2PCBN technology has been found to provide a 20-40% greater efficiency when compared to traditional COB technology.

What is a COB?

A COB (chip on board) is a popular light engine application in which multiple LED chips are mounted directly to a circuit board. This allows for lower cost, better thermal properties, and improved performance. COBs are used in many different applications, from commercial and industrial lighting to medical and home lighting. In addition, COB technology is also well-suited for applications that require a high level of control and flexibility.

GU2PCBN vs. COB?

When comparing the two technologies, the advantages and disadvantages must be weighed. GU2PCBN is a much more efficient technology and is capable of producing a greater level of luminance than traditional COBs. However, due to the complexity of GU2PCBN design, it can be more expensive and difficult to set up than a COB, especially when working with a large number of LEDs. Additionally, GU2PCBN may require additional components, such as power conversion and thermal interface materials, that can increase the cost.

On the other hand, COBs are much easier to set up and require fewer components, which makes them a good choice for low-cost applications. They also offer lower thermal resistance, which can be beneficial for applications that require a longer life span or higher performance. However, COBs are not as efficient as GU2PCBN and typically offer a lower level of luminance.

GU2PCBN Working Principle

The GU2PCBN technology utilizes a global uniform power conversion board to deliver a significantly improved efficiency. This is accomplished by spreading out the LED power conversion, which maximizes the amount of power delivered to each LED chip, while still maintaining a uniform light spectrum across the board. The power conversion board is typically placed below the LED chips and is connected to each individual LED via a separate circuit.

The GU2PCBN technology also utilizes a heat-management system that efficiently dissipates heat to ensure maximum brightness and efficiency. Heat is removed from the LED chips and transferred through the power conversion board and into a heat-sink or other cooling system. This helps to reduce the risk of thermal failure and helps to ensure that the LED light fixture works as efficiently as possible.

GU2PCBN Application Fields

The GU2PCBN technology is suitable for a variety of applications. It can be used for residential, commercial, and industrial lighting, as well as for architectural, automotive, and medical applications. In addition, the technology is well-suited for applications that require a high level of control, such as dimming, color changing, and motion sensing. The ability to spread out the power conversion board over a larger surface area can also help to minimize glare and increase the light output of the LED fixture.

Conclusion

As LED lighting continues to evolve, new technology such as GU2PCBN are gaining more traction in the industry. GU2PCBN offers a significant level of efficiency and performance, as well as cost savings, that can make a big impact in the LED lighting industry. By understanding the differences between COBs and GU2PCBN and weighing the advantages and disadvantages, it is possible to make the right decision for any particular application.
