C-γ LED Luminous Intensity Test Goniophotometer Single Pillar for Streetlight and Spot Light

1. Introduction

Sinlge Pillar Goniophotometer Test System (Luminous Intensity Distribution Test System) is designed according to LM-79 and CIE standard regarding C-γ test solution, widely applied to test LED,HID,CFL and other luminaire, like floodlight, dowlight, panel light, streetlight and so on. The measuring parameters includes spatial intensity distribution curve, cross section spatial intensity distribution curve, isolux distribution curve, luminance limitation curve,area luminous flux,luminaries efficiency, UGR glare class, total luminous flux,effective luminous flux,utilization factor and etc. All the test data can be saved as IES file which can input to Dialux directly, also the data can be output as PDF and excel files for analysis purpose.

1)For Indoor Lighting fixture: upward light ratio, downward light ratio, max allowable spacing height ratio, luminaire limitation curve, utilization factor,budgetary estimate table.

2)For floodlight: half peak side angle, type B luminous intensity distribution data, zonal luminous flux distribution data, space luminous intensity curve.

3) For streetlight: max allowable spacing height ratio, upward light ratio, downward light ratio, zonal flux, luminous intensity, utilization factor.

2. Application

LED luminiare includes: downlight, spotlight, streetlight

6. Lab requirement

1) Dark room dimension: 3m(H)*2.5m(W)*8m(L) above, or designed according to lamp size and lab size. The rotating console and detector are put in dark room. Dark room (includes wall, ceiling and floor) should be coated with dull dark paint, or be covered with black carpet or black cloth.

2) Control room: 2.5m(H)*3m(W)*3m(L). The control cabinet, computer and printer are put in control room.

3) The temperature of dark room should be controlled by air conditioner according to CIE requirement.

4) Pego will provide lab design support according to actual conditions after order confirmed.
