The full name of EN13032-1 is Light and lighting Measurement and Presentation of photometric data of lamps and luminaires. It is edited by CEN in 2004. This standard is a guide to procedures referring where necessary to the relevant CIE, ISO and CEN publications . We will introduce the clause 184.108.40.206 Goniophotometer type 3 in this article.
The following is the original content of EN 13032-1 220.127.116.11 Goniophotometer type 3.
18.104.22.168 Goniophotometer type 3
The light source is rotated around a vertical axis, a mirror arrangement around a horizontal axis. The photometer head is fixed.
The mirror shall not limit the view of the light source from the photometer head and to be plane. They should have a spectrally constant reflectance or their spectral reflectance shall be considered for the V(λ) correction of the used photometer head. Attention shall be paid to the polarization of the radiation due to reflection by the mirrors and the local situation of the reflection.
The goniophotometer of type 3 can be distinguished as follows:
1) Type 3.1:
a ) centre of mirror in rotation center;
b ) light source is rotated around the mirror on a fixed radius.
2) Type 3.2:
a ) light source in rotation center;
b ) the mirror is rotated around the light source on a fixed radius.
3) Type 3.3:
Light source and mirror are led on two oppositely orientated fixed radius around the rotation center.
LISUN designed the LSG-5000 Moving detector goniophotometer according to the EN 13032-1 Clause 22.214.171.124 standard. The measuring distance is from 5m to 30m. It can measure all types lighting sources, LED or HID luminaries such as indoor and outdoor luminaries. Roadway luminaries, street lamps, flood lights and other kinds of luminaries. And we also designed different kinds of dimension goniophotometer according to different sizes of tested samples. We will update the software and testing parameters according to the updating of the EN 13032-1 standard.
