The Application Of Diamond in The Field Of Lighting

In today's rapidly changing LED lighting technology, heat dissipation has always been a key factor restricting its performance improvement. As LED technology continues to move towards high light efficiency and high power, high-power LED packaging technology has a direct impact on the performance and lifespan of LEDs due to its complex structure and process. Especially in high-power application scenarios such as car headlights, outdoor strong light lighting, stage lighting, etc., the problems of worsening light attenuation and decreased stability caused by poor heat dissipation have become urgent challenges for the industry to solve. Recently, Chinese companies have successfully developed diamond based ultra-high power density packaging technology, providing a new solution to this problem.

 

 

1 Excellent heat dissipation performance, breaking through traditional limitations

Traditional high-power LED packaging technology often uses ceramics and other materials as substrates. However, in high-power application scenarios such as car headlights and outdoor strong light lighting, the heat dissipation performance of ceramic materials is limited, which can easily lead to problems such as increased light decay, shortened lifespan, and even burning. Diamond materials, with their excellent thermal conductivity, have become the key to solving this problem. It is reported that the thermal conductivity of the new diamond based ultra-high power density packaging technology can reach up to 1800W/(m • K), which is more than 10 times that of ceramic materials. This breakthrough in heat dissipation performance enables LED chips to operate stably at higher power, achieving continuous improvement in brightness and greatly extending the service life of LEDs.

2 Compact size, efficient lighting effect

In addition to excellent heat dissipation performance, this new product also offers a variety of specifications to choose from, with the minimum size of a single lamp reaching 5 * 5mm, perfectly compatible with mainstream market specifications. This compact size design not only facilitates installation and maintenance, but also greatly reduces maintenance costs. At the same time, the new product has excellent light efficiency, which can meet various high light efficiency requirements, especially suitable for applications such as street lamps that require high brightness and long-term lighting.

 

3 Powerful power, excellent optical performance

In terms of optical performance, the new diamond based ultra-high power density packaging technology also performs well. By optimizing the packaging structure design, the loss of light during propagation has been significantly reduced. A single lamp can achieve a power of 60W, with a luminous flux of over 6500lm, and a brighter and more uniform light distribution. This feature makes the new product perform well in high brightness and high uniformity requirements such as projectors, providing users with a clearer and more delicate visual experience.

 

4 Advanced packaging technology enhances reliability

Diamond materials not only have high thermal conductivity, but also have a small coefficient of thermal expansion, which helps to reduce thermal stress caused by temperature changes and prevent problems such as cracking or peeling. The new product of diamond based ultra-high power density packaging technology adopts its own advanced packaging technology, which further enhances the reliability, stability, and service life of the device. This feature is particularly important in professional lighting scenarios such as stage lights, ensuring that the equipment maintains excellent performance even under high-intensity operation and meets the needs of professional users.

 

5 Innovation leads the future and showcases enormous potential

The launch of the new diamond based ultra-high power density packaging technology not only brings significant performance leaps to the lighting field, but also opens up new paths for the development of high-end lighting applications. This technology has shown great potential for applications in various fields such as outdoor lighting, automotive lighting, drone lighting, projectors, and stage lighting. At the same time, it once again confirms that diamond, as an excellent extreme material, has great potential that scientists and scholars should explore and explore in depth.
