Light-Conversion Film

Product Overview

Light-conversion film is a functional greenhouse film developed to meet the needs of facility agriculture. By adding a specialized light-conversion agent during production and leveraging the principle of light conversion, it optimizes the spectral quality of sunlight. It converts ultraviolet and green light—wavelengths that contribute little to plant photosynthesis—into blue-violet and red-orange light required for plant growth, effectively enhancing light energy utilization within the greenhouse and boosting crop yields. This product also features temperature-adaptive regulation, resistance to UV-induced aging, and insect-attracting pest-repelling functions, fully meeting the production requirements of pollution-free vegetable cultivation. It is an ideal配套 greenhouse film for facility planting, seedling raising, and cultivation during low-light seasons. Customized inquiries are supported, with one-on-one solution quoting services available from the manufacturer to meet the配套 needs of various planting scenarios.

Working Principle

The core functionality of light-conversion film relies on its built-in light-conversion agent, with the light conversion process following fundamental principles of optics and plant physiology. First, ultraviolet and green light in sunlight contribute little to the photosynthesis of most vegetable crops; not only can they not be fully utilized by the crops, but they also accelerate material aging of the greenhouse film and attract certain pests. The light-conversion agent specifically absorbs these two wavelength bands and, through molecular energy-level transitions, re-emits the absorbed energy as red-orange and blue-violet light—the wavelengths with the highest photosynthetic efficiency for plants—directly increasing the total amount of effective photosynthetically active radiation inside the greenhouse. Second, the conversion efficiency of the light-conversion agent exhibits temperature adaptability: in low-temperature environments, conversion efficiency increases, allowing more light energy to be converted into heat absorbed by crops and air inside the greenhouse, achieving a warming effect; in high-temperature environments, conversion efficiency decreases, reducing excess heat release to prevent overheating and enabling dynamic temperature regulation. Additionally, the agent's absorption of ultraviolet light directly reduces the degradation rate of the greenhouse film's polymer materials, extending its service life. At the same time, pests exhibit visual preferences for short-wavelength light; after the light-conversion film filters out these attracting wavelengths, it guides pests to escape outside the greenhouse, reducing the incidence of indoor pests and diseases, decreasing pesticide use, and aligning with the requirements of pollution-free cultivation.

Core Functions

1. Light Conversion for Efficiency and Yield Increase: The light-conversion agent transforms ineffective ultraviolet and green light into red-orange and blue-violet light needed by crops, increasing the total amount of effective photosynthetically active radiation inside the greenhouse, improving light energy utilization, and supporting dry matter accumulation in crops.
2. Temperature-Adaptive Regulation: In low-temperature environments, conversion efficiency increases, releasing more heat to warm the greenhouse; in high-temperature environments, conversion efficiency decreases, reducing heat release to regulate the greenhouse temperature, adapting to seasonal temperature demands.
3. Resistance to UV-Induced Aging: The light-conversion agent absorbs ultraviolet light, reducing its degradative effects on greenhouse film materials and extending the film's service life.
4. Insect Attraction and Pest Avoidance: By filtering out short-wavelength light that attracts pests, it guides pests to escape outside the greenhouse, reducing indoor pest and disease occurrence and lowering pesticide usage.
5. Adaptation to Pollution-Free Cultivation: With no additional harmful additives and reduced pesticide use, this product fully complies with production standards for pollution-free vegetables.

Field Trial Results

According to publicly available field trial data from domestic and international research teams, using this light-conversion film to grow common facility vegetables such as cucumbers and tomatoes can increase yields by 10–20% or more. It should be noted that these trial results were obtained under specific environmental conditions; actual yield improvements will be influenced by local lighting conditions, crop varieties, cultivation management levels, and other factors. Specific outcomes should be determined based on local field test data.
