Goniophotometer for lamps
and small luminaire |
The goniophotometer type RIGO
801 utilizes a new image-resolving CCD measuring technique for
determining
ray data and luminous intensity distributions. The correct
determination of the luminous intensity distributions (LVK) of lamps
and luminaries is performed far within their photometric limiting
distance on the basis of image resolved measurements of luminous
intensity distributions. A CCD-camera is moved by a goniometer
around the measuring object at rest on a spherical surface, with the
radius of this sphere being fixed only by the field angle of the
camera. Thus, the goniometer can also be installed in small
laboratories |

Feature |
-
Correct determination of the
luminous intensity distributions
(LID) of lamps and luminaries far
within their photometric near-field
range
-
Output of lid data in all common
file formats (EULUM-DAT, TM14, IES,
Calculux, ...)
-
Capture of ray data
-
Saving in various standard formats
(ASAP, Speos, Zemax, LightTools,
LucidShape, TracePro)
-
Small dimensions of the set-up
-
Measuring in normal position, no
movement of the measuring object
photometric database(LumCAT)

Application |
- LIDs, spectral characterization;
object assumed to be a point
- luminance distributions
- 4D-luminance distribution, ray
distribution in the space
-
Efficiency ratio, power input,
temperature behavior

Specification |
|
Size of measuring object |
20 x 20 x 20 mm³ ~ 300 x 300 x 300 mm³ |
| Space required |
1300 x 1300 x 1900 mm³ |
|
Movement |
The measuring camera and the illuminance meter are moved
on a sphere around the lamp (two independent axes
arranged vertically
to each other (θ, Φ)). |
|
Travel path |
Φ = -2° ~ 362°, θ = 0° ~ 360° |
|
Measuring position of the luminaire |
Normal position, no movement of the measuring object.
The whole goniometer can be swivelled, which permits
different measuring positions to be realized. |
| Measuring width |
270 mm |
|
Positioning accuracy |
Φ < 0.02°, θ < 0.05° |
|
Repetitive accuracy |
Φ < 0.01°, θ < 0.02° |
