Emits in the 610–640 nm range with narrow spectral width, enabling:

  • High-CRI warm white LEDs (Ra ≥ 90)

  • Deep red display pixels for enhanced contrast

  • Color consistency across batches (Δx, Δy < 0.005)

2. High Energy Efficiency

Converts blue chip light (450–460 nm) to red output at up to 100 lm/W, enhancing total system efficacy and reducing power loss.

3. Process Compatibility

  • Ready for integration into existing 450nm blue LED chip lines

  • Uniform D50 = 15μm option ensures smooth phosphor-silicone dispersion

  • Fully compatible with COB, SMD, CSP packaging workflows

4. Long-Term Stability in Harsh Environments

  • Heat resistance up to 300°C

  • Chemically inert in silicone binders and LED encapsulants

Blended with YAG yellow and green phosphors, this red phosphor corrects spectral deficiency in warm white LEDs, achieving:

  • High CRI (Ra > 90)

  • Low color temperature (2700K–3500K)

  • Enhanced color fidelity in home, museum, and commercial lighting

2. Industrial & Specialty Lighting

  • Industrial tubes, task lights, and spotlights in warehouses/factories

  • Enhanced visibility in low-light or red-sensitive environments

  • Stable for long-hour use in high-temperature enclosures

3. Decorative & Stage Lighting

  • High-saturation red effect for architectural highlights, concerts, exhibitions

  • Works with RGB systems for full-spectrum stage applications

4. Display Backlight & Pixels (Mini/Micro-LED)

Frequently Asked Questions (FAQ)

Q1: What makes this red phosphor better for warm white LED production?

A1: It compensates for the lack of red emission in blue/yellow phosphor mixes, improving CRI (Ra ≥ 90) and supporting warmer light tones (2700K–3500K).

Q2: Is it compatible with 450nm chips?

A2: Yes. This red phosphor is optimized for 445–465 nm chips, especially 450–460 nm where excitation is most efficient.

Q3: What’s the benefit of the high-density version?

A3: Better heat dissipation and improved mechanical strength, recommended for high-power LEDs or applications with thermal cycling.

Q4: Can I test before bulk purchase?

A4: Absolutely. We offer 100g sample units for testing under your production conditions.

Q5: What's the typical lead time for large orders?

A5: For bulk contracts, production capacity can scale to 5000kg/month, with lead times typically 7–15 days including shipping.
