LSG-1900B goniofotometr is near field type C automatic goniophotometric instrument for luminous intensity distribution measurement. The LSG-1900B uses a constant temperature detector. It is used for industrial laboratory photometric data measurements of small luminaires, such as down light, bulb light, etc.

Near Field Goniophotometer Measurement:

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.

Specyfikacja:
• It meets the requirements of CIE, IEC, LM-79 – miesięczna opłata za użytkowanie i standardy GB
• It can do C-γ and B-β measurement
• The luminaires under test will keep the burning point from moving
• The luminaries under test rotates around an angle of (γ) ±180° (or 0-360°) and the luminaries rotates around itself with an angle of (C) ±180°  (or 0-360°)
• Maximum size of luminaires under test: Φ300mm (diameter)×550mm (height); Weight: 20kg; Current: 10A
• Distance from lamp to detector: 1250mm
• Luminosity Testing Range: Light Intensity 0.015cd～10^7cd (detector)
• The accuracy of angle: 0.2°; The resolution of angle: 0.01°
• Accuracy of photometry: Class A
