LEP Technical

I. Spectral Features: Full-Spectrum Solar Simulation to Unlock Plant Growth Potential

The plasma light source (LEP), with its unique full-spectrum coverage (290-1800 nm), stands as the artificial light source closest to natural sunlight. Its spectrum comprises 30% invisible light (21% infrared and 9% ultraviolet) and 70% visible light, with red, green, and blue light ratios (41/32/27) nearly identical to sunlight. This spectral profile provides multidimensional support for plant growth:

1. Ultraviolet (UV) Benefits: Weak UVA radiation promotes protein, sugar, and organic acid synthesis, enhances seed germination rates, and suppresses mold growth, all while remaining safe for plants and humans.

2.  Infrared (IR) Contributions: Accelerates stem elongation and flowering while regulating photoperiod responses.

3.  Visible Light Efficiency: Red and blue light account for 68% of visible light, with a color rendering index of Ra92 and a color temperature of 5000-6500K (equivalent to natural light at 10 AM–12 PM), precisely matching photosynthetic requirements.

4. Irradiation Performance: A 300W LEP achieves a power density ≥1000 W/m² (AM1.5 standard), with uniformity and stability meeting AAA-grade solar simulation standards. Its central illuminance reaches 114,100 Lux at 15 cm and maintains 28,000 Lux at 120 cm (equivalent to midday sunlight), adapting to diverse cultivation scenarios.

II. Energy Efficiency Advantages: Energy-Saving Performance with Enhanced Crop Quality

Comparative studies by the Dutch Agricultural University highlight LEP’s superior performance in plant cultivation:

1. Optimized Growth Efficiency: Compared to high-pressure sodium (HPS) lamps, ceramic metal halide lamps, and LEDs, LEP reduces growth cycles by 33% and increases biomass by 31% (e.g., lettuce), while accelerating flowering and fruiting.

2. Quality and Yield Synergy: LEP-grown tomatoes show a 38% increase in fruit solids, 21% higher single-fruit weight, richer nutritional content, and enhanced flavor (e.g., optimized sugar-acid ratio), alongside uniform appearance.

3. Resilience and Sustainability: LEP-irradiated plants exhibit no spider mite infestations, demonstrating pest resistance. Operational costs drop by 33%, radiant heat decreases by 34%, and energy efficiency aligns with low-carbon goals.

III. Application Features: Longevity, Low Maintenance, and Adaptability to Modern Agriculture

1. Stability and Cost-Effectiveness: LEP offers flicker-free lighting, stable color temperature, and >80% luminous flux retention after 50,000 hours. Its lifespan exceeds HID lamps by 34%, with 40% lower energy consumption, ensuring long-term economic benefits.

2. Thermal Management: Compared to LEDs, LEP generates less radiant heat, minimizing plant thermal stress and enabling use in enclosed environments.

3. Versatility: Ideal for multi-layer vertical farms, greenhouse supplementation, and controlled environments, particularly excelling in high-value crops (e.g., medicinal herbs, ornamental flowers).
   

Conclusion

Plasma light sources (LEP) redefine plant lighting standards through full-spectrum solar simulation, high energy efficiency, and low environmental impact. By overcoming the spectral limitations of traditional lighting, LEP prioritizes energy savings, quality enhancement, and yield optimization, offering revolutionary solutions for precision agriculture, facility horticulture, and ecological research. As photobiological studies advance, LEP’s potential to bolster global agricultural sustainability and food security will continue to expand.
