Specifications:
LSG-2000 goniophotometer is

1. An automatic light distribution testing system;
2. Test distance from 5m to 30m is adjustable;
3. Measure all type of lighting sources and luminaires, such as indoor and outdoor luminaires, roadway luminaires, and flood lights with high accuracy;
4. Achieve the testing program of CIE C-γ, CIE B- βand CIE A-α;
5. Testing results can be used as international lighting Design software, and meets the requirements of CIE and IESNA standards.

Measure parameters:

• luminous intensity data,
• luminous intensity distribution,
• zonal luminous flux,
• luminaries efficiency,
• luminance distribution,
• coefficient of utilization,
• luminance limitation curves glare,
• maximum ratio of distance to height,
• equal illuminance diagrams,
• curves of luminaires vs lighting area,
• lsocandela diagrams,
• efficient luminescence angle etc.

Rotation features:

1. The tested luminaire rotates around the mirror with an angle of (γ)±180°°(or 0-360°),
2. The tested luminaire rotates around itself with an angle of (C)±180°(or 0-360°).
3. Using technical and high level redirector which is made up by special metal fiber, no winding, interllective startup and stop ,keep stable rotating continuous testing and low noise.
4. The position and working state remain the same as it is under working.

• Special collimation device with laser cross line, convenient and accurately fix the position of the tested luminaries.

• The accuracy of angle: 0.1° , Resolution of angle : 0.01°.
• Accuracy of photometry: CIE class A (standard class).
• The tested data meets the international and national standard requirements.

IESNA file format output can be transfered by other illumination and luminaire design software.

• RS-232C standard interface and windows operating boundary surface with both Chinese and English, convenient to connect with all kinds of computers
