Spectral conversion film


Light-conversion greenhouse film, also known as a spectral conversion film. This is a special type of functional plastic film used in agriculture to convert less-usable parts of sunlight (like UV) into more photosynthetically active light, typically red or blue light, which plants can use more efficiently.


Details Description

Light-conversion greenhouse film, also known as a spectral conversion film. This is a special type of functional plastic film used in agriculture to convert less-usable parts of sunlight (like UV) into more photosynthetically active light, typically red or blue light, which plants can use more efficiently.

Here’s an overview:

Light Conversion Greenhouse Film (Spectral Conversion Film)

Item

Details

Name

Light Conversion Greenhouse Film / Spectral Conversion Film

Material Base

Usually PE (Polyethylene) with light-converting additives

Main Function

Converts UV or violet light into red or blue light to enhance photosynthesis and plant growth

Light Conversion Types

UV → Red light / UV → Blue light / UV → Red + Blue

Common Additives

Rare-earth luminescent materials (Europium, Terbium compounds), organic luminescent dyes

Target Wavelengths

Converts <400 nm UV into ~450 nm (blue) or ~660 nm (red) light

Benefits

 

→ Enhanced Photosynthesis

Red and blue lights are most effective for photosynthesis

→ Faster Plant Growth

Promotes biomass accumulation and flower/fruit formation

→ Better Light Utilization

Makes use of UV light that is otherwise not used by plants

→ Potential Pest Reduction

UV conversion reduces UV attraction to pests like whiteflies

Usage Areas

High-tech greenhouses, vegetable production, flower cultivation, fruit crops

Working Principle

These films contain light-conversion pigments or phosphors that absorb high-energy UV or violet light, and then re-emit it as lower-energy visible light (red or blue). This process is called photoluminescence.

Example Applications

Tomatoes / Peppers / Strawberries – respond well to red light.

Leafy Greens (Lettuce, Spinach) – benefit from both red and blue light.

Flowers (Chrysanthemums, Roses) – flowering and color development can be improved.

The exact conversion efficiency depends on the film quality and additive type.

Film cost is typically higher than standard PE, but yields and quality improvements can offset that.

Some films also retain other functions (anti-drip, anti-fog, anti-dust, IR-blocking, etc.)

Agricultural Technology

Which crops are suitable for using reflective film?

Light-transmitting mulch film is a functional mulch film that can convert part of the spectrum of natural light into a spectrum beneficial to crop growth. It has the functions of increasing temperature, retaining moisture, and improving light conditions. The following are the main types of crops suitable for using light-transmitting mulch film and the reasons for analysis:
