HEP Lighting Technology
Ceravision’s High Efficiency Plasma (HEP) light is particularly suited to medium and high power applications. HEP technology is a new and unique genre of electrodeless, radio frequency (RF) driven lighting invented by Ceravision. The unique design of Ceravision's proprietary plasma burner allows the efficient collection and distribution of the light produced. This proprietary technology uses radio frequency in the microwave range to create a high intensity plasma discharge. It comprises four integrated elements:
- Quartz RF resonator/plasma burner (the ‘lamp’).
- Transition unit (the system that couples the RF energy from the source into the resonator).
- RF microwave source.
- AC/DC power supply.
The resonator/burner contains an inert gas and metal halide salts. RF microwave energy resonating within the lamp ionizes the gas to form a plasma that combines vaporises the metal halide salts, emitting an intense, bright light. This method of producing light has proved to be extremely efficient, using less energy to make more light of a better quality and with the flexibility to tailor spectra.
The light is emitted from a very small source, which enables the light to be accurately focussed and distributed and provide greater optical performance.The absence of electrodes, or filaments, enables the use of a wide range of chemicals; chemicals, which if used in electrode lamps, would react with electrode materials. HEP can deliver intense radiation throughout the spectrum by careful selection of the components of the chemical dose. The resulting radiation is a combination of atomic and molecular emissions.
The technology lends itself particularly to high-output applications including ultra-violet (UV) for water sterilisation and grow lighting for horticulture.
Light is now a value added utility in many sectors. Offering a wide spectral range and energy efficiency, Ceravision's HEP lighting technology has the flexibility to offer economic solutions in high value global markets.
