Horticulture & Grow-Lights
The world’s food production systems face major challenges in meeting the demands from rising populations whilst dealing with scarcities of land, water and energy and issues of globalisation and climate. In addition to food crops, biotechnologists are increasingly looking to use plants for the development of new medicines.
Grow-lights, along with efficient horticulture procedures, enable accelerated plant development, extended growing periods and higher crop yields; they can also influence plant physiology. Around the world, an increasing range of crops is produced under grow-lights. Whilst this may have improved production, it has sometimes been at the expense of product value (eg taste). This is because some lighting technologies emit suboptimal-spectra.
It was believed that plants use only light from within the Photosynthetically Active Radiation (PAR). Research now indicates plants make use of UV-B to improve disease resistance, bio-mass, strength and leaf thickness and could be useful in plant taxa used for medicine. These factors are facilitated by HEP but are costly to implement in other technologies including LEDs.
The ionCORE™ lighting system delivers high levels of illumination from a very small source. The small source size allows design flexibility for luminaires to be compact. This enables installations to minimise the shadowing from the units and make the most effective use of any natural daylight.
In horticulture, HEP’s flexibility in features, performance, and economics provides technical and commercial advantages over other grow-light technologies and makes it a highly persuasive technology with enormous potential:
- Fewer failure mechanisms prolong life
- Highly efficient with excellent illuminance
- Dimmable with no colour shift
- More complete light spectrum, including UV-A and UV-B
- Flexibility to tailor spectra economically to suit crops and to influence plant physiology
- More energy efficient than HID grow-lights
- Excellent illuminance provides light that penetrates plant canopies more than fluorescent and LEDs
- High output maintenance factor prolongs output over time compared with HID or HPS.
Future Markets & Applications for HEP
Energy efficiency is a global driver within many markets and Ceravision’s core technology has the ability to address these markets. By exploiting the flexible nature of the core technology we are able to facilitate a variety of power levels (400 W to 2.0 kW) and spectra ranging from visible to UV light.
The following are just a few applications that are being addressed:
- UV-C Treatments for commercial non-chemical control of plant diseases on crops to reduce losses. The protective effects of UV-C treatments, which stimulate plant defence, can induce resistance against a range of pathogens pre and post-harvest on crops.
- UV-C for germicidal irradiation in Water Sterilisation: a purely physical, chemical-free process. To efficiently reduce parasites such as cryptosporidia or giardia, which are extremely resistant to chemical disinfectants, and to remove chlorine and chloramine species from water.
- UV-C for germicidal irradiation in Air Purification to reduce airborne-mediated microbial diseases such as influenza and tuberculosis which present major public health challenges.
Please contact us if you would like to discuss the possibilities of utilising HEP technology in these sectors, or indeed any other applications that you may have in mind.
Ceravision's Spectral Design Services
Ceravision welcomes the opportunity to work with interested parties to optimise spectra for different types of plant characteristics and develop bespoke grow-light solutions. The electrodeless discharge chamber has fewer of the chemical constraints imposed by the materials in traditional light sources. This allows numerous spectral ranges to be designed, which in turn could help biotechnologists to create spectra with the ability to engineer ‘designer’ plants without genetic modification or chemical usage.
Ceravision would welcome the opportunity to collaborate with companies and institutions whose expertise lies within these fields, to exploit the benefits of plasma lighting in horticulture and other specialist markets including UV-C sterilisation. Ceravision can offer tailored research plus the design and development of grow-lights tailored for a particular crop or outcome: this could include spectral development, dosing, lamp design, power options and manufacture.
