Gholographics Company

GONIO PHOTOMETER

Gholographic Company can offers Goniophotometer that can measure almost all types of light sources and luminaires including various kinds of lamps, LED luminaires, indoor and outdoor luminaires,and flood lights. It can achieve CIE A, CIE B, CIE C solutions with different software.

GHGO-CS CENTRIC MOVING MIRROR GONIOPHOTOMTER

Goniophotometer rotates the tested light source in the prescribed burning position around the vertical axis and a reflecting mirror rotates around the horizontal axis(Main axis). A auxiliary axis will rotate toward the opposite direction simultaneously. The combined motion of the luminaire and mirror permit luminous measurement at the direction of any horizontal or vertical angle without tilting the luminare and without disturbing the luminous intensity during measurement.The photometer head is located at a fixed position of the limiting photometric distance in front of the reflecting mirror to gather the light in each direction.



Powerful measuring functions

Luminous intensity data, luminous intensity distribution curve, efficient luminescence angle, spread angle, zonal luminous flux, luminaires efficiency, total luminous flux, upper luminous flux, lower luminous flux, available average illuminance curve, coefficient of utilization, luminance limitation curves, glare, maximum ratio of distance to height, iso-Illuminance diagrams, curves of luminaires vs lighting area, Isocandela diagrams etc.
