The activities of
the Photometry Laboratory of the
NTUA concern:
- Scientific
research (funded and non-funded).
- Quality assurance
tests and measurements on lighting equipment, material and apparratuses.
- Conduction of
seminars about lighting and photometry.
- Laboratory
training of NTUA students.
The
technical capabilities of the laboratory are the following:
-
Measurement of luminous flux and luminous efficiency
of every type of lamp (incadescent, fluorescent, metal hallide, etc.) with the
use of photometric arrangements and standard lamps.
-
Measurement of lamps life-time.
-
Diagrams of polar distribution of luminous
intensity.
-
Measurement of efficiency of lighting fixtures.
-
Water-tightness tests on lighting fixtures, under
artificial rain.
-
Measurement of glare characteristics of lighting
fixtures.
-
Measurement of reflectivity, absorbance and
transmittance of several materials.
-
Measurement of sun radiation (intensity and spectral
composition).
-
Luminance and illuminance measurements in road and
tunnel lighting systems
-
Illuminance measurements on lamps and lighting
fixtures.
-
Luminance measurements on surfaces, lamps and
lighting fixtures.
-
Measurements of electrical characteristics of
ballasts by means of standard ballasts.
-
Tests on lamp receptacles under controled conditions
(voltage, temperature, humidity).
-
Colorimetric measurements on lamps and lamp covers.
-
Colorimetric measurements on industrial products
(plastics, textiles, etc.).
-
Calibration of instruments and apparratuses with the
use of standard lamps.
-
Calibration of photometers with the use of standard
lamps.
