Plant Lighting Core Pain Points
Targeted solutions for key technical challenges in plant lighting
Spectrum Mismatch
Ordinary light sources lack critical photosynthetic wavelengths, resulting in low efficiency and slow growth
Poor Stability
Continuous operation causes spectrum drift and light decay, affecting growth consistency
High Energy Cost
Low light utilization increases cultivation costs significantly
Process Compatibility
Must work with SMD, COB, high-power packaging while balancing flowability and stability
Weak Crop Specificity
Different crops need different spectrums; generic solutions fail customization needs
LDE-660 Deep Red Phosphor
665nm peak wavelength precisely matches Chlorophyll a absorption peak
Nitride-Based Deep Red Phosphor
112nm ultra-wide FWHM covers 600-700nm critical photosynthetic range. Nitride matrix ensures excellent thermal/humidity stability for 12-16h/day continuous greenhouse operation.
| Parameter | Specification | Significance |
|---|---|---|
| Peak Wavelength | 665±1nm | Matches Chlorophyll a absorption peak |
| FWHM | 112nm | Covers 600-700nm critical range |
| Particle Size D50 | 13μm | Balances flowability and stability |
| Relative Brightness | ≥100% | Ensures light output performance |
| 1000h Light Decay | <3% | Long-term stable operation |
LDE-660 uses nitride matrix with excellent thermal/humidity stability, supporting 12-16h/day continuous operation in high-humidity greenhouses (≥95%RH) with <15% light decay over 5 years. The 665nm peak precisely targets Chlorophyll a, while 112nm FWHM extends to Chlorophyll b region for maximum photosynthetic efficiency.

| Crop Type | Stage | Light Recipe | Effect |
|---|---|---|---|
| Leafy Vegetables | Full Cycle | 60-70% + 20-30% + White | 7-10 days shorter cycle |
| Fruiting Vegetables | Vegetative | 50-60% + 30-40% + White | Robust plants |
| Fruiting Vegetables | Flowering | 55-65% + 15-25% + Far Red | Higher yield |
| Flowering Plants | Bloom | 50-60% + 20% + Far Red | Extended flowering |
| Seedlings | Nursery | 50-60% + 30-40% + White | 30% better survival |
Pair LDE-660 with 450-460nm blue chips. Leafy vegetables: Red:Blue = 3:1~4:1. Fruiting vegetables (flowering): 5:1~6:1. Each batch includes spectrum reports with ±0.003 color coordinate precision.
