For LED lamp manufacturers, lighting solution providers, and electronic component distributors seeking reliable red phosphor materials, our Chemical Stability Nitride LED Red Phosphor Powder delivers exceptional performance in demanding applications.

Based in Shenzhen, China, we've supplied this material to over 200 LED manufacturers across Asia, Europe, and North America since 2005, supporting projects from residential warm-white lighting to high-CRI museum installations.

1. Proven Chemical and Thermal Resilience in Real-World Conditions

Unlike standard red phosphors that degrade when exposed to humidity or cleaning agents, our nitride-based formula (Sr, Ca)AlSiN₃:Eu maintains stable performance in harsh environments. During our quality testing of outdoor LED fixtures in coastal regions, samples showed less than 3% luminous flux decline after 5,000 hours at 85°C/85% relative humidity — a critical advantage for outdoor landscape lighting or industrial workshop applications where environmental exposure is constant.

Key Benefit: The material withstands continuous operation at temperatures up to 300°C without color shift. This thermal stability translates to approximately 30% longer fixture lifespan in high-power LED downlights compared to conventional red phosphors.

2. Precise Color Performance for Warm-White Applications

Our phosphor achieves chromaticity coordinates of x=0.6440±0.003, y=0.3555±0.003 with peak emission at 623.5±2.0 nm. When combined with yellow-green phosphors in standard ratios (typically 15-20% red phosphor by weight), LED systems consistently reach CRI ≥90 and produce warm-white output in the 2700K-3500K range.

Warm-White Residential and Hospitality Lighting

Residential LED bulbs, hotel corridor lighting, and retail display fixtures requiring 2700K-3500K color temperature benefit from the accurate red component this phosphor provides. The high CRI ensures fabrics, wood finishes, and skin tones appear natural rather than washed out.

High-CRI Professional Applications

Museum display lighting, medical examination rooms, and photography studios demand CRI ≥90 to accurately render colors. Our phosphor's narrow emission spectrum (610-630 nm) fills the red gap in LED spectra without excessive far-red output that would waste energy on invisible wavelengths.

Industrial and Outdoor LED Fixtures

High-power LED tubes for workshops, outdoor landscape lighting, and street lighting benefit from the phosphor's chemical resistance to moisture and cleaning agents, plus thermal stability under continuous high-power operation. Our material has performed reliably in IP65-rated outdoor fixtures operating in temperature ranges from -20°C to +50°C ambient.

Custom LED Development Projects

Automotive interior lighting manufacturers and smart home lighting developers use our phosphor in prototype development due to our small-batch capability (MOQ: 100g). We've supported LED module developers in testing different red phosphor ratios for tunable white lighting systems, providing spectral data for each batch to ensure consistent results.

We produce this phosphor in our 38,200 m² facility established in 2005, with dedicated R&D capabilities for custom formulations. Each production batch undergoes spectral analysis using integrating sphere spectrophotometers to verify emission wavelength accuracy within ±2.0 nm of specification. Particle size distribution is measured via laser diffraction to ensure D50 remains at 15±2.0 μm for optimal dispersion in silicone encapsulants.

Our monthly supply capacity reaches 5,000 kg for standard specifications, with flexibility to prioritize urgent orders. We maintain buffer stock of raw materials to prevent supply chain disruptions — during the 2022 global supply chain crisis, we maintained 100% on-time delivery to existing customers by securing six months of critical precursor inventory.

For small-batch trials, we offer 100g minimum orders with full spectral and particle size reports, allowing R&D teams to validate performance before scaling up. One Japanese LED manufacturer tested our phosphor alongside three competitors in their 3000K LED development project; our material's lower batch-to-batch variation (chromaticity deviation<0.002 across five production lots) led to their selection for mass production.

Every batch includes detailed test reports covering:

✓ Spectral emission curve (measured at 450nm excitation)

✓ Peak wavelength accuracy

✓ Chromaticity coordinates

✓ Particle size distribution

✓ Luminous efficiency measurement

We provide these reports within 48 hours of production completion, enabling customers to verify material specifications before integration into their production lines.

Achieving Target CCT

We recommend starting with 18% red phosphor, 82% yellow-green phosphor by weight for 3000K warm-white. Adjust red phosphor proportion by ±2% to shift CCT by approximately ±150K.

Preventing Phosphor Settling

For silicone encapsulation, we suggest mixing phosphor at 40-50°C to reduce viscosity, then degassing under vacuum for 15 minutes before dispensing. Our particle size specification (D50=15μm) minimizes settling compared to larger particles.

Storage Requirements

Store unopened packages in conditions below 30°C with relative humidity under 60%. Shelf life is 12 months sealed; once opened, use within 3 months and reseal immediately after each use to prevent moisture absorption.

While our standard formulation targets 623.5nm peak emission, we can adjust the formula for applications requiring different wavelengths:

• 605-615 nm range: Suitable for orange-red output

• 640-650 nm range: Deep red emission for horticultural LED or medical lighting

• Excitation wavelength adjustment: Modify europium doping levels for chips outside 445-465nm range

Customization requires minimum order quantities of 5kg with 15-20 business days for formula development and testing. Contact our technical team with your target specifications for feasibility assessment.

Our phosphor is manufactured lead-free and meets:

✓ RoHS directives for European markets

✓ REACH compliance for chemical substance registration

✓ California Proposition 65 requirements

We provide material safety data sheets (MSDS) and compliance certificates with each shipment to support your export documentation needs.
