Welcome to EINLIGHTRED
Eindhoven Institute for Lighting Technology Research and Education
Let there be light ...
Light, energy of the highest form, has always appealed to human
imagination. This is not surprising as light makes our surroundings visible
in our daily lives. It is because the existence of light that we know what
is going on in the world around us, in the grand design of the cosmos.
At day-time there is the sun, making our surroundings visible; at night we
see twinkling stars and receive light that is already billion of years on
its way, providing us with information on Galaxies from remote outskirts of
the universe. In all these cases light is being created by the plasma. In a
plasma, movements of charged particles (electrons orbiting around ions)
constantly change in velocity, causing the radiation of light. By means of
spectroscopy, the study of colour analysis, we can learn a lot about the
objects that radiate light, the chemical position of the stars and
galaxies, and follow the evolution of the universe.
As said light is generated by means of the movement of charged particles in
plasmas, hot gases having the special feature of charged particles. The
plasma state is, following the solid, liquid and the gas state, the fourth
aggregation state of matter. It is known that more than 99,9% of the
visible matter in the universe is in the plasma state. The study of the
light of stars, nebulae and galaxies has demonstrated how rich and diverse
the plasma state is. Apart from the difference in chemical composition,
temperature and pressure, we also have a wide variety in geometrical
structures that can be realized by means of electric and magnetic fields.
But also in technology the plasma state shows a very rich diversity and
that is why so many applications exist. Apart from generating light plasmas
can be used for material treatment such as welding, cutting, etching and
deposition, and in environmental technology for the investigation of
pollution and cleaning of gases.
In the light institute EINLIGHTRED we deal with the study of fundamental
aspects of light generation and its technology. This is for an important
part plasma physics and therefore strongly related to other branches of
plasma science such as plasma chemistry.
What does EINLIGHTRED represent?
- We are in frequent interaction and close contact with technological
research institutes of ( Philips
Lighting in Eindhoven and Aachen and Philips
in Eindhoven), ASML
and Draka Comteq.
- The research methods used are both theoretical and experimental. As a
part of theory formation a simulation package is being constructed;
for the experiments many different types of diagnostics are in use in
our Poly-diagnostic Lab.
- We are part of the Eindhoven University of Technology
(Department of Applied Physics); our primary task is the
training of engineers and PhD's applied physics. At university,
EINLIGHTRED has been embedded in the Research School
CPS (Centre for
Plasma Physics en Radiatio mnTechnology), links with the research groups
ETP) have been established. Inter-departemental contacsts with
the Centre for Sustainable Development
Arranged according to technological application we have the following main
- Light for illumination; Lamps, with or without electrode.
- Light for image processing; Plasma-TV.
- Light for engraving; EUV-lithography.
- Light for environmental–analysis; Spectrochemical analysis.
- Light for disinfections; UV-generation.
- Light conduction; Plasmas for glass fibre manufacturing
- Light for acceleration: laser wake field acceleration.
