Two Decades of Innovation: The COC Breakthrough

Since pioneering ceramic-based heat dissipation in the early 2000s to solve LED thermal management challenges, Sansi has perfected its proprietary Ceramic-on-Chip (COC) technology – eliminating traditional PCB layers to enable shorter thermal paths, 30% faster heat dissipation, and superior reliability. The newly upgraded COC streetlights are the culmination of:

106+ ceramic structural designs
496+ material formula refinements
2,117+ firing process trials
10,825+ optical simulations
41,344+ performance tests

"COC represents a fundamental reengineering of LED architecture," said Song, the marketing director of Sansi. "By directly bonding chips to ceramic substrates, we achieve unmatched efficiency and lifespan – protected by global IP portfolios."

Performance That Powers Sustainable Cities

The C0820-QR series combines 214.7 lm/W system efficacy with adaptive long-life power systems and precision optics, delivering:

67.4% energy savings vs. conventional HID fixtures

Equivalent to the amount of carbon dioxide absorbed by about 160 trees in one day Near-zero maintenance costs for municipal operators.

Already deployed in Hong Kong-Zhuhai-Macao Bridge, Beijing-Xiong’an Smart Highway, and Shenzhen-Zhongshan Link, Sansi’s ceramic lighting solutions are proven at scale.

Full-Stack R&D: A Rare Industry Advantage

Sansi’s vertically integrated R&D ecosystem (16 Research Institutes) – spanning materials science, IC microelectronics, optics, and industrial design – enables complete control over COC technology. With,

500+ researchers
880+ patents
Leadership in China’s 863 Program and National Key R&D Projects

Global Recognition & Availability

Honored as a National High-Tech Enterprise and "Little Giant" Specialist Innovator, Sansi’s technologies illuminate iconic venues from New York’s Times Square to Asian Games venues.
