Goniophotometer

Integrated Darkroom Design Accurate Measurement for Spatial Luminous Intensity & Color Distribution of Luminaires

Suitable for all kinds of indoor lamps, flood lamps, road lighting lamps and all kinds of light distribution performance test, total luminous flux, luminaire efficiency and electrical parameters (voltage, current, power, power factor) measurement.Test data can be saved as IESNA(*.ies), CIBSE(*.CIB), EULUMDAT(*.LDT), CIE(*.cie), CEN(*.cEN) and other formats, which can be directly used as the input data of international general lighting design software.

Features

• Integrated Darkroom
  The system adopts a unique design scheme combining low stray obscural and extinction cylinder. Users do not have to build a special dark room for optical testing, and can achieve light distribution measurement of light sources and lamps under office conditions.
• Mutual Data Correction
  The combined design of spectroradiometer and special precision photometer match and correct the spectral data during photometric measurement, so that the photometric measurement accuracy can be achieved.
• Comprehensive Testing Capabilities
  The system integrates the functions of spatial luminous intensity distribution curve, total luminous flux and spatial color distribution (average color and spatial color non-uniformity), truly realizing the comprehensive test of the spatial characteristics of luminaires.
• Highly Integrated System with Easy Operation
  The test system is highly integrated and easy to use, which integrates two rotation axes, AC-DC power supply, measuring unit and measuring and control software.
