Background:
LuminaLED Technologies is mainly supplied high-performance LED for various lighting applications. They specialize in producing energy-efficient, long-lasting LED chips that deliver superior brightness and color accuracy. And be aimed to provide lighting solutions that meet the evolving needs of the market and contribute to energy conservation efforts.
Now they faced a significant challenge in optimizing the performance and reliability of their LED chips. Conventional packaging materials used for LED chips, such as FR4, had limitations in terms of thermal management, electrical conductivity, and miniaturization. These limitations resulted in reduced brightness, increased thermal stress, and limited design flexibility for them.
Solution:
Due to the LED requiring very good heat dissipation, the size also needs to be small to match the LED, we recommended DPC ceramic PCB for them because DPC ceramic circuit boards enable precise miniaturization of LED chip packaging, allowing for compact designs and greater flexibility in product development. This feature enabled LuminaLED Technologies to create smaller, more versatile LED chip packages, expanding their range of lighting applications.
Result and Benefits:
LuminaLED Technologies expressed high satisfaction with the implementation of DPC ceramic circuit boards in their LED chip packaging and introduced two new customers for us.
