Nitride system: heat & humidity resistant
Concentrated spectrum, high signal recognition
Recommended headlight phosphor LD-4453 features broad-spectrum emission (115.9 nm FWHM) to effectively reduce glare, with a dual particle-size design for high-power packages. FL-Y04MB delivers 112% relative brightness for long-distance illumination; its aluminate system is heat-resistant and suitable for engine-bay environments. For interior lighting, HB-5049 provides 128.4 nm broad-spectrum emission with no harsh glare; 2700 K warm white is suitable for long-duration use. For instrument backlight, LD-2762 offers concentrated green emission; its silicate system is stable and reliable. For signal lamps, FL-5841/FL-6040 provide orange-red light with strong penetration; the nitride system resists heat and humidity.
For headlight applications, an LD-4453 + FL-5841 blend can improve color rendering and visibility in rain and fog. All recommended products are specified with “sealed storage 24 months” and “temperature rating ≤85°C”, with lumen depreciation ≤20% @ 50,000 h—fully matching a 5–10 year vehicle service cycle. Multiple particle-size options (e.g., 7 μm / 12 μm) support SMD, DIP, and high-power automotive LED packages with no extra process changes.
Automotive-grade vs general lighting phosphor
Key Performance Comparison
| Performance Metrics | Automotive-grade Phosphor | General Lighting Phosphor |

| Lumen Depreciation Control | Very low (≤20% @ 50,000 h; matches vehicle lifetime) | High (≥30% / 20,000 h) |
| Chromaticity Accuracy | Extremely high (tolerance ±0.003, meets automotive spec) | Average (tolerance ±0.008) |
| Lot-to-lot Consistency | Very high (ensures mass-production consistency, reduces rework) | Average (large lot variation) |
| Package Compatibility | Strong (supports SMD/DIP/high-power packages) | Limited (only standard packages) |
