KEY ADVANTAGES
Ceramiclite LED Material Applications
Fluorescent Transparent Ceramics (FTC) represent the next-generation replacement for traditional phosphor materials that mix phosphor powder with silicone. This innovation enables the development of high-quality, high-power LED and laser diode (LD) light sources with exceptional reliability, efficiency, and thermal stability — meeting the demands of industrial, automotive, and outdoor lighting applications.
Advantages:
Material Performance Highlights:
1). High Internal Quantum Efficiency (IQE): >98%
2). Superior Luminescence Thermal Stability: Maintains brightness under extreme temperatures
3). High Transmittance: Ensures minimal optical loss
4). Excellent Physical and Chemical Stability: Outstanding resistance to corrosion and aging
5). High Thermal Conductivity: Up to 10 W/m·K, enabling efficient heat dissipation for long-term reliability
LED/LD Light Source Performance:
1). Power Range: 150 W – 2000 W
2). High Power Density: Up to 60 W/mm²
3). Reliability: Luminous attenuation <5% over 100,000 hours (LM-80 verified)
4). Long Lifetime: More than 10 years with minimal depreciation
FTC enables consistent performance under high power and high thermal load, making it ideal for industrial-grade LED and LD systems.
Excellent luminescence thermal stability
The internal quantum efficiency (IQE) of fluorescent transparent ceramic at 150℃, 200°C and 250℃ is 1%, 7% and 15% of that at room temperature respectively. While the lQE for the phosphor powder is 22%, 35% and 45% in sequence.
According to LM-80 testing, luminous attenuation of FTC-based LED light source within 100,000 hours operation is below 5%.
