Our Red Nitride Phosphor Powder is a high-performance fluorescent material specifically engineered for industrial LED tube manufacturing. Designed for demanding environments like factory workshops, warehouses, and underground garages, this phosphor delivers exceptional brightness, thermal stability, and production efficiency—enabling manufacturers to produce industrial-grade LED tubes that operate reliably for 50,000+ hours under harsh conditions.
By combining 101 lm/W luminous efficiency with 300°C thermal resistance and 99.9% purity, this phosphor addresses the core challenges of industrial lighting: energy efficiency, durability in extreme environments, and batch-to-batch consistency for large-scale production.
Product Advantages
Optimized for High-Speed Industrial LED Tube Production
With a flexible particle size range of 5-20 microns (typical 7-15μm), this phosphor ensures uniform mixing with blue LED chips in SMD and imitation lumen packaging processes. This adaptability minimizes production defects and material waste—critical for manufacturers running high-volume assembly lines producing industrial LED tubes at scale.
Superior Energy Efficiency for Long-Hour Industrial Operations
At 101 lm/W luminous efficiency, this phosphor outperforms standard silicate phosphors (typically 85-90 lm/W) by 12-18%. For industrial facilities operating LED tubes 12-24 hours daily, this higher efficiency directly translates to reduced electricity consumption over the 50,000+ hour lifespan of the LED tubes.
Extreme Environmental Durability
Engineered to withstand temperatures up to 300°C (compared to 200°C for typical silicate alternatives), this nitride-based phosphor maintains stable performance in poorly ventilated industrial spaces where heat accumulation is common. Combined with excellent acid/alkali resistance and moisture-proof properties, it extends LED tube operational life in challenging environments like food processing plants or underground parking facilities where humidity and temperature fluctuations are frequent.
Batch Consistency for Quality Assurance
99.9% purity eliminates impurity-related defects such as uneven light emission or color shift—ensuring every industrial LED tube meets brightness and color standards required for large-scale factory projects. This consistency is backed by a 2-year shelf life when stored properly, supporting long-term inventory planning without material degradation.
Global Compliance and Safety
Fully RoHS and CE compliant with lead-free formulation, ensuring safe integration into international supply chains and meeting regulatory requirements for industrial lighting projects across global markets.

Application Scenarios
Our red nitride phosphor is widely adopted across multiple industrial and commercial lighting applications:
Industrial LED Tube Lighting
Primary use case for factory workshops, warehouses, logistics centers, and underground garages requiring 12-24 hour continuous operation. The 300°C thermal stability ensures reliable performance in heat-intensive environments, while 101 lm/W efficiency addresses the energy consumption concerns of large facilities with extensive LED tube installations.
Traffic & Safety Lighting
Ideal for traffic signals, warning lights, and emergency indicators where bright red emission (659.2 nm peak) ensures high visibility in harsh weather conditions including rain, fog, and extreme temperatures. The phosphor's moisture resistance prevents performance degradation in outdoor installations.
Commercial Decorative Lighting
Suitable for stage lighting, architectural accent lights, and retail displays requiring vibrant red color with extended operational durability. The stable chromaticity coordinates (x=0.6815, y=0.3196) ensure consistent color appearance throughout the product lifespan.
Particle Size Recommendations
Based on common industrial LED tube packaging methods:
SMD Packaging (Surface-Mount LED Tubes): 7-10 μm range for optimal chip adhesion and uniform light distribution
Imitation Lumen Packaging: 10-15 μm range for higher brightness density requirements
Custom Applications: Ultra-fine (<7 μm) or coarse (15-20 μm) grades available upon request
Production & Integration Guidelines
To maximize performance and ensure seamless integration into industrial LED tube manufacturing:
Mixing Ratio
Combine red nitride phosphor with yellow phosphor (e.g., YAG:Ce³⁺) in ratios adjusted based on target correlated color temperature (CCT) and brightness requirements for specific industrial lighting applications. Contact our technical team for formulation recommendations based on your LED tube specifications.
Dispersion Process
Apply vacuum degassing and controlled stirring to maintain uniform phosphor distribution in silicone matrix. Avoid high-shear mixing that may damage particle structure and affect luminous efficiency.
Curing Temperature
Use silicone encapsulants with curing profiles ≤150°C to prevent thermal stress on phosphor particles. Compatible with major LED-grade silicones including DOW SYLGARD and Shin-Etsu KER series.
Quality Control Checkpoints
Particle size distribution verification (laser diffraction method)
Luminous flux measurement at specified drive current
Color consistency testing (CIE 1931 chromaticity diagram)
Thermal cycling test for industrial environment simulation
