PARUS Research and Development ?

PARUS Research − Since 2003

The future of passible
We believe new technology to change the world, starting with a small greatest idea and continuous enthusiasm been completions. These big and small ideas are leading new creation to development humanity.

In 10 years ago, PARUS predicted the future of grow light so PARUS developed LED grow lights and Plant Factory System, and have continued research and development to improve our products.

By 2050, the world population will reach about 9.5 billion, due to the global warming cultivable land will rapidly decrease, and it will cause food crisis. The global warming is irreversible and environment experts predict that 5 degrees(ºC) of temperature increase can cause 85% of lands devastated.

PARUS will continue to develop the convergence technology (IT, BT, NT, CT, ET) for agriculture that is not affected by the environmental change.

Research of the wavelength for growing plants
A comprehensive test using LED and General lights

Most of the plants photosynthetic characteristics is similar though, it is essential to research the optimal condition of growing plants in terms of productivity and energy saving.
The optimal wavelength absorbed by plant varies by its species, so it is very important to test response of a target plant to different wavelength and find appropriate wavelength for growing that plants.
PARUS R&D center developed the analyzing system, which makes comparison tests using same species with different wavelength to find out optimum and new better one.


 
 

Research of the efficiency of growing plants with LED grow light


Because of the nature of having long−wave wavelength, the Sun light or the traditional grow light such as HID, FL or Metal Halide is hard to adjust its wavelength, but LED only to the use of the plants got the necessary wavelength can be more efficient and save energy.
It is important to understand that a target plant prefers which wavelength and environmental condition to cultivate plants in a large scale of greenhouse or plant factory.
PARUS conducts the wavelength analysis of plant growth using various wavelengths and its combinations, and gets data for shortening the growing period, improving the quality, and reducing energy cost and management cost.

You can see the full data of the presented sample.

Research of mushroom growth with LED

Analysis of the optical absorption characteristics of mushroom can present a solution for efficient production and energy savings.


 
 

Research of LED wavelength use of fish light

LED fish-luring light
In response to the specific wavelength, fishes gather towards it.
A LED fish-luring light was developed through this principle, fishing boats uses fish lights to capture specific fishes.


 
 

Insect vision and sensitivity to wavelength LED Pest control

Human eyes can detect visible spectrum known as rainbow color, define the color of objects by reflection of light − mixture of wavelength.
Wavelength detection of insects:
A range of wavelength detected by insects is a little different by the kinds of insects though, most of insects can detect a certain range of wavelength: 285~580nm. Insects response to this range of light, even very low intensity, and gather to light in the distance.
For example, some lamps have lots of insets around while the lights on, but some are not. It is related to wavelength combination that each lamp has, insects are attracted and gathered to lamps which their favorite wavelength composed.
