Professional LED Phosphor Supplier | 15+ Years Expertise | High-CRI Solutions |
1. Product Overview |
The Professional's Choice for High-CRI Warm White Lighting As a premier manufacturer based in Zhuhai, China, with over 15 years of material science expertise, we present the SDR631Z01 Nitride Red Phosphor. This high-performance material is engineered specifically to solve the "thermal degradation" and "color shift" issues found in traditional oxide-based phosphors. By utilizing a robust (Sr, Ca)AlSiN₃:Eu crystal structure, SDR631Z01 enables LED packagers to achieve CRI ≥90 (R9 > 50) while maintaining stability in harsh, high-temperature environments (up to 300°C). It is the ideal solution for high-end hospitality lighting, industrial fixtures, and automotive LEDs. |

3. Why Switch to Nitride Phosphor? (Performance Gap) |
1. Unmatched Thermal Stability (300°C vs 150°C) Traditional red phosphors suffer from severe thermal quenching above 150°C. SDR631Z01 remains stable up to 300°C (continuous) and withstands peaks of 500°C, making it perfect for: • Enclosed downlights with poor heat dissipation • High-power industrial high-bay lights Result: A documented 30% increase in fixture lifespan and reduced warranty claims. |
2. High Color Rendering (CRI 90+) Standard LEDs often lack red spectrum coverage. Our phosphor fills the 620-630nm gap. Retail: Makes fabrics and merchandise pop Food: Enhances the appetizing look of meat and produce Result: Achieves R9 > 50, critical for meeting Energy Star and high-end project specs. |
3. Energy Efficiency Don't sacrifice brightness for color quality. With 80-100 lm/W efficiency, you can produce a 10W bulb that rivals the brightness of a competitor's 12W bulb, saving energy while delivering superior light quality. |
4. Engineer's Guide: Integration & MixingBased on our lab data for 3030 SMD Packages. | |
Recommended Mixing Ratio (Target: 3000K Warm White, CRI 92) | |
| Component | Weight % / Role |
| Yellow Phosphor (YAG:Ce) | 65% - Provides base brightness/spectrum |
| Red Nitride (SDR631Z01) | 25% - Lowers CCT, boosts CRI & R9 |
| Green Phosphor (β-SiAlON) | 10% - Fine-tunes duv (distance from Planckian locus) |
Encapsulation Best Practices
Pre-Mixing: Disperse in silicone (15-20 wt%) using mechanical stirring (500-800 rpm, 10 mins). Process Temperature: Compatible with all standard curing profiles (e.g., 150°C x 2 hours). Particle Choice: We recommend our standard D50=15μm for most SMD applications to prevent settling. For COB, ask about our 20-25μm grade. |

7. Frequently Asked Questions (FAQ) |
Q1: Can SDR631Z01 withstand reflow soldering (260°C)? A: Yes. It is thermally stable up to 500°C (short-term). For surface mount devices, we recommend using high-temperature silicone to protect the package, but the phosphor itself will not degrade during reflow. |
Q2: What is the shelf life? A: 24 months when stored in sealed containers at room temperature (<60% RH). We recommend vacuum sealing any unused portion immediately after opening. |
Q3: Can I visit your factory? A: Absolutely. We welcome clients to visit our production facility in Zhuhai. Please contact our sales team to schedule a tour and technical audit. |
