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.

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.

Recommended Mixing Ratio (Target: 3000K Warm White, CRI 92)

We ensure batch-to-batch consistency through rigorous testing:

✓ Optical Check: Wavelength tolerance ±1.5nm

✓ Physical Check: Laser diffraction for particle size

✓ Reliability: 1000-hour aging test at 300°C

✓ Chemical: ICP-MS purity verification (99% min)

Detailed COA (Certificate of Analysis) and spectral reports are provided with every shipment.

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.
