High Precision Rotation Luminaire Goniophotometer

What is goniophotometer definition?
LSG-1890B/LSG-1800A goniophotometer is automatic goniophotometric instrument
for luminous intensity distribution measurements with facility for rotating the
light source. The LSG-1890B/LSG-1800A uses a constant temperature detector,
Japanese motor and German precision angle coder which keep the test results
with high accuracy. It is for industrial laboratory photometric data
measurement of all kinds of luminaries such as LED luminaries, HID lamps,
fluorescent lamps and so on.

Standard:
Full meet the EN13032-1 clause 6.1.1.3 goniophotometer type 1, COMMISSION
DELEGATED REGULATION (EU) 2019/2015, CIE-70, CIE-121, IES LM-79, IES LM-75, IES
LM-80 and ect.

Measurement:
Luminous Intensity Data, Luminous Intensity Distribution, Zonal Luminous Flux,
Luminaries Efficiency(Option),Luminance Distribution,Coefficient Of
Utilization, Luminance Limitation Curves Glare, Maximum Ratio of Distance to
Height, Equal Illuminance Diagrams, Curves of Luminaires VS Lighting Area,
Isocandela Diagrams, Efficient Luminescence Angle, EEI, UGR, etc.

Specification:
• The goniophotometric instrument can do the B-β test with two pillars and the
C-γ test with single pillar & multi-function jigs
• Test Max Luminaires size and weight: LSG-1890B is 2000mm/60kg and LSG-1800A
is 1600mm/50kg
• The tested luminaries rotates around an angle of (γ)±180°(or 0-360°) and
the tested luminaries rotates around itself with an angle of (C)±180°(or 0-
360°)
• Luminosity Testing Range: Illuminance 0.01lx~99,999lx; Light Intensity
1.0cd~10^7cd (detector)
• Angle accuracy: LSG-1890B is 0.1°, LSG-1800A is 0.2°
• Photometry Accuracy: CIE Class A (Class L is option)
• Testing Accuracy: 2%(Under Standard lamp); Stray Light: less than 0.1%
• English version software can run in Win7, Win8 or Win10, Win11
• LISUN goniophotometer software can export CIE, IES, LDT and other format
files. These kinds of format files can be transferred by other illumination and
luminaire design software such as DiaLux.

What are the types of goniophotometer?
The types of Goniophotometers can be basically divided into Type A, Type B and
Type C. For a detailed description, please refer to the 1987 edition of CIE 70.
The difference between them lies in the way the lighting equipment rotates
during the measurement and the photometric data obtained during this
measurement.

How does goniophotometer measures?
Goniophotometer is a device used to measure the light distribution performance
of lamps. Goniophotometer measures the spatial light intensity distribution of
lamps or light sources, total luminous flux and lamp efficiency and other
parameters.

Goniophotometer need to work in larger darkroom. Use low-reflectivity materials
in the room to avoid reflected light from entering the probe. Depending on the
arrangement of the measuring light path, two measurement schemes can be used to
measure the luminous flux: the illuminance integral method and the luminous
intensity integral method.
