Plasma Light Engine

Ceravision's HEP plasma grow-lights can be dosed with different chemical to deliver spectral outputs tailored to suit particular plants and or  targeted outcomes. The UV-B and UV-A from the UV420 is vital for quality crops. UV enhances a crop's quality and nutritional and medicinal properties.  UV-B light can help reduce greenhouse chemical usage, organic cultivation .

The plasma technology utilises Ceravision’s patented quartz radio frequency (RF) technology.  With a compact and versatile form factor and the ability to change the combination of materials in the discharge chamber, numerous spectral outputs can be created to meet specific needs. The small light source can be accurately 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 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 light obstruction occurs over a small angle; with little change in viewing position; this means that shadows have sharp 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' plants to improve food crops and for innovative new medicines without genetic modification or chemical usage.

HEP's Light Emitting Resonator
This light emitting resonator drives the spectral output from Ceravision's new UV grow-light

The HEP plasma grow-light has a spectral output from 280-550 nm providing UV-B, UV-A and blue light using a patented chemical dose. Integrated with PAR grow-lights, this UV grow-light offers technical and commercial advantages:

  • Blue light with UV-A and UV-B influence plant physiology
  • Materials can be economically tailored to create spectra for particular crops
  • Excellent illuminance so that light penetrates plant canopies
  • High lumen maintenance compared to prolong energy intake
  • Small high intensity light source minimises luminaire shadowing
  • UV-B at 280 to 290 nm is the most efficient wavelength range to stress plants.
