ionCORE Plasma Light Engine

Ceravision's HEP plasma grow lights use a light engine that has the flexibility to deliver spectral outputs tailored to suit particular plants and targeted outcomes.  These spectra can enhance a crop's visual appearance, nutritional and medicinal properties, and reduce greenhouse costs.

The ionCORE plasma light engine utilises Ceravision’s patented Quartz Radio Frequency (RF) luminaire technology along with ultra-reliable magnetrons.  With a compact and versatile form factor and the ability to change the combination of materials in the discharge chamber, ionCORE™ can create specific spectral power distributions to meet highly specific lighting needs.  The small light source can be accurately and reproducibly positioned in a precisely designed optical environment to deliver as much light as possible to a target area.  

HEP Plasma Point Source Light

The plasma light point source is a single identifiable localised source The small capsule in HEP Plasma light can be dosed with different chemicals to tailor spectra for horticulture grow lights.10mm diameter and 20mm length, the size of the end of a little finger.  There are three main benefits of single point source lighting:

  1. Supports the design of efficient compact luminaires;
  2. The obstruction of the light occurs over a small angle; with little change in viewing position; this means that shadows cast have sharply defined boundaries;
  3. Directional strength; enables optically efficient reflectors to be designed to precisely and efficiently redirect light to achieve desired distributions eg wide grow-light reflectors suitable for large growing areas, or narrow reflectors for growing tables.

Lamp Doses Tailored to Suit Applications

Lamp doses can be accurately specified, which in horticulture and Agri-Tech applications can be crop specific.  Our scientists are able to optimise HEP’s variables of dose, spectra, power, reflector materials and optics, to deliver light that economically enhances crop production efficiencies and yields and really add value. 

This ability to design tailored spectra will help scientists create 'designer' plants for innovative new medicines without genetic modification or chemical usage.

The HEP plasma grow-light has a spectral output from 280 to 550 nm with blue-light, UV-A and UV-B, and green light using a patented chemical dose.  Ceravision's HEP plasma grow-light source.Compared with other grow-light technologies, the plasma grow-light offers technical and commercial advantages:

  • Blue light with UV-A and UV-B to influence plant physiology
  • Green light to mediate seed germination and improve photosynthesis, flowering and growth 
  • Materials can be economically tailored to create spectra for particular crops
  • Excellent illuminance so that light penetrates plant canopies more than fluorescent and LEDs
  • High lumen maintenance compared to HID or HPS
  • Small high intensity light source minimises luminaire shadowing
  • More energy efficient than HID grow-lights.
