    Goniophotometer with Rotating Luminaire

    Be utilized to measure photometric parameters of luminaires for LED road lighting fixture, room lighting fixture and projecting lighting fixture, such as spatial intensity distribution curve, spatial iso-intensity curve, intensity distribution curve on each section (represent by right-angled coordinates or polar coordinates), iso-illuminance distribution curve on the plain surface, luminance limitation curve, luminaire efficiency, glare grade, effective beam angle, upward luminous flux ratio, downward luminous flux ratio, total luminous flux, effective luminous flux, utilization factor and electric parameters(voltage, current, wattage, power factor) and etc.
  • Type-C Luminaire Goniophotometer

    Type-C Luminaire Goniophotometer

    This is an automatic goniophotometric instrumentation for luminous intensity distribution measurements with facility for turning the luminaire. It belongs to the Type 3 geometrical construction (C-γ). It was designed for cost-effective configuration for industrial laboratory to perform the photometric measurement of indoor and outdoor lighting fixture.
  • Miniature Luminaire Goniophotometer

    Miniature Luminaire Goniophotometer

    This goniophotometer is satisfied to CIE C-r test requirement of CIE127 standard, 1.0 or 3.16m dark room should be integrated. It automatically draws the curve of luminous intensity distribution curve and measures the angle of light beam. The test system supports IESNA file which is able to be input to other lighting design software.
  • Luminaire Goniophotometer with rotating mirror

    Luminaire Goniophotometer with rotating mirror

    It belongs to LM-79 measurement condition for light intensity distribution measurement. It can realize the CIE B-Β, A-Α and C-Γ conditions and the test results can be sued as internatinal lighting desgin software with IESNA standards. Its adjustable measuring distance from 5m to 30m for measuring all types of luminaires, such as indoor & outdoor luminaires, roadway lighting, street lighting.
