In high-end applications such as retail lighting, architectural lighting, and horticultural lighting, are you facing these challenges?
| 🎨 Insufficient Color RenderingTraditional red phosphors perform poorly in mixed white light, causing skin tone distortion and poor merchandise display effects | 🔥 High-Temperature Light DecayWhen module temperatures exceed 150°C, ordinary phosphors experience rapid brightness degradation and shortened lifespan | ⚠️ Compliance RisksExport shipments to European and American markets get held at customs due to missing SGS reports or RoHS certification |
Our 99.9% Purity Nitride Red Phosphor (Sr,Ca)AlSiN₃:Eu is engineered to solve these problems. It not only achieves precise red light emission at 629.5nm, but maintains crystal structure stability even under extreme 300°C environments—a performance level that silicate or sulfide red phosphors simply cannot match.

2. Performance Comparison & Competitive Advantages
Proven Data That Withstands Testing
Our aging laboratory conducted 5,000-hour 85/85 testing (85°C temperature, 85% humidity). Results prove: the nitride structure provides superior hydrolysis resistance that traditional materials cannot match.
| Comparison Dimension | Our Nitride Red Phosphor | Traditional Phosphors |
|---|---|---|
| Moisture & Heat Resistance | No degradation in 85/85 test ✓ Suitable for IP65+ harsh outdoor environments | Prone to moisture hydrolysis ✗ Limited outdoor use |
| High-Temperature Resistance | Stable at 300°C ✓ Extends high-power fixture lifespan by 30%+ | Rapid brightness drop >150°C ✗ Shortened lifespan |
| Color Rendering | Easily achieves R9 >50 ✓ Meets museum, medical standards | Difficult to improve R9 values ✗ Poor red rendering |
| Chemical Stability | Acid & alkali resistant ✓ Compatible with more adhesive types | Decomposes with acid/alkali ✗ Limited compatibility |
| Batch Consistency | Color coordinate deviation<0.002 ✓ Reduces production line adjustments | Large batch color variations ✗ Frequent bin adjustments needed |
3. Process Application Guidelines
Professional Guidance from Our R&D Laboratory
We don't just sell materials—we provide complete technical support. Our application engineers have over 15 years of LED packaging experience and can provide customized formulation solutions based on your specific needs.
A. Formulation Design Services
Whether your goals include:
Adjusting specific color temperatures (2700K - 6500K)
Improving color rendering index (CRI>90, R9>50)
Optimizing the balance between efficacy and color rendering
Adapting to specific chip wavelengths or packaging processes
| Precise Mixing RatiosBased on your chip and adhesive system | Measured DataSpectral graphs and color coordinate data | Verification SupportSmall-batch testing before mass production |
💡 Fine-Tuning Reference: Each 1% change in red phosphor shifts CCT by approximately 70-80K
B. Process Optimization Recommendations
| Process Step | Expert Recommendations |
|---|---|
| Adhesive Preheating | 40-50°C → Reduces silicone viscosity, prevents powder agglomeration |
| Mixing & Stirring | Vacuum planetary mixer → Must eliminate dead zones to ensure SDCM<3 |
| Vacuum Degassing | >20 minutes → Thoroughly removes micro-bubbles, prevents voids after curing |
| Anti-Settling Control | Dispense within 2 hours after mixing → High-density material settles easily |
| Curing Conditions | 150°C / 2 hours → Avoid excessive temperatures causing phosphor thermal quenching |
