Plasma Light Engine

Ceravision's plasma grow-lights can be dosed with different chemicals to tailor spectral outputs for particular plants or targeted outcomes. The UV-B and UV-A from the UV420 is vital for quality - enhancing a crop's nutritional and medicinal properties; the UV-B helps to reduce hazardous chemical usage for a more enviornmentally friendly organic cultivation.

The grow-lights use our patented quartz radio frequency (RF) technology.  With a compact and versatile form factor and the ability to change material combinations in the discharge chamber, we can create various spectral outputs. And the small light source can be positioned accurately in a precisely designed optical environment to deliver as much light as possible to a target area.

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 so 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 the variables of dose, spectra, power, reflector materials and optics, to deliver light that economically enhances crop production efficiencies and yields and really adds 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

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:
 - Create bespoke spectra for particular crops
 - High illuminance to penetrate plant canopies
 - Good lumen maintenance prolongs benefits
 - Minimises luminaire shadowing
 - UV-B is the most efficient range to stress plants.

Further Information

Future Applications

Delivering flexible spectral outputs, plasma lighting offers practical economic solutions in horticulture and other applications requiring natural solar levels of UV-A and UV-B, or UV-C for sterilisation.

Plasma Light Technology

Ceravision’s plasma grow-lights, with a spectrum providing UV-B, UV-A and blue herald a new scientific future in horticulture lighting and UV-B is beneficial for humans producing the vitamin D essential for health.
