AC COB Modules: Revolutionising Lighting Solutions

Introduction

In the world of lighting technology, AC COB (chip-on-board) modules have emerged as a game-changer. These modules offer a wide range of applications and advantages over traditional lighting solutions. In this blog post, we will explore the various aspects of AC COB modules, including their working principles, applications, benefits, and future trends.

What is an AC COB module?

An AC COB module is a compact lighting module that integrates multiple LED chips directly onto a single circuit board. Unlike DC COB modules that require an external driver, AC COB modules can be directly connected to an AC power source, eliminating the need for additional components.

Applications of AC COB Modules

AC COB modules find applications in various fields, including:

Indoor lighting: They are widely used in residential, commercial, and industrial settings for general lighting purposes.

Outdoor lighting: AC COB modules are suitable for street lighting, floodlights, and architectural lighting due to their high brightness and efficiency.

Automotive lighting: They are used in headlights, taillights, and interior lighting in vehicles.

Display lighting: AC COB modules provide uniform and high-quality lighting for signage, retail displays, and exhibition booths.

Difference Between AC COB and DC COB Modules

The main difference between AC COB and DC COB modules lies in their power supply requirements. AC COB modules can directly operate on AC power, while DC COB modules require an external driver to convert AC power to DC power for operation.

Working Principles of AC COB Modules

AC COB modules utilise a series-parallel configuration of LED chips on a single circuit board. They incorporate a rectifier circuit that converts the incoming AC power to DC power, which is then distributed to the LED chips. This design ensures stable and efficient operation of the module.

Advantages of AC COB Modules

AC COB modules offer several advantages, including:

Simplified design: The integration of multiple LED chips onto a single board simplifies the overall lighting system design.

Cost-effective: AC COB modules eliminate the need for external drivers, reducing the cost of the lighting system.

High efficiency: AC COB modules provide high luminous efficacy, resulting in energy savings and reduced environmental impact.

Compact size: The compact size of AC COB modules allows for versatile installation options in various lighting fixtures.

Long lifespan: AC COB modules are designed for long-term operation, ensuring a reliable and durable lighting solution.

Choosing the Right AC COB Module

When selecting an AC COB module, consider factors such as the required brightness, colour temperature, beam angle, and compatibility with the lighting fixture. Additionally, ensure that the module meets safety standards and has the necessary certifications.

Installation and Usage Considerations

Proper installation and usage of AC COB modules are crucial for optimal performance and safety. Follow the manufacturer’s guidelines and recommendations for installation, thermal management, and electrical connections. Ensure that the module is adequately cooled to prevent overheating.

Lifespan and Reliability of AC COB Modules

AC COB modules are designed to have a long lifespan, typically ranging from 50,000 to 100,000 hours. However, the actual lifespan depends on various factors such as operating conditions, thermal management, and the quality of the components used.

Price Range of AC COB Modules

The price of AC COB modules varies depending on factors such as power output, brand, and additional features. Generally, higher power output and advanced features result in higher prices.

Future Trends of AC COB Modules

The future of AC COB modules looks promising, with ongoing advancements in efficiency, colour rendering, and smart lighting capabilities. Integration with IoT (Internet of Things) technology and the development of tunable white and RGBW (Red, Green, Blue, and White) options are expected to drive the growth of AC COB modules in the coming years.

Conclusion

AC COB modules have revolutionised the lighting industry with their compact design, high efficiency, and simplified installation. Their wide range of applications, cost-effectiveness, and long lifespan make them an attractive choice for various lighting projects. As technology continues to advance, AC COB modules are expected to play a significant role in shaping the future of lighting solutions.
