LSG-1800: Rotation Luminaire Goniophotometer

Function of this light measurement:

According to the requirements of the National Standards, CIE, IESNA, through the rotating lamps and lanterns, to realize many measurement methods such as B-β, A-a and C-γ, etc. These methods are used for light intensity measurement and many other photometric parameters of indoor lighting lamps and lanterns, throwing light lamps and lanterns, road lighting lamps and lanterns, including: space light intensity distribution, the light luminous intensity distribution curve of any section (which can use right angle coordinate system or polar coordinate to display), space light intensity curve, plane illumination distribution curve, brightness limit curve, band flux, glare grade, lamps and lanterns efficiency, effective emitting angle, upward flux rate, downward flux rate, total flux of lamps and lanterns, effective flux, utilization fact, the whole space chromaticity unevenness of LED lamps and lanterns and electrical parameters (voltage, current, power, power factor), etc. It can do double column or single pillar work.


LSG-1800 performance index:

High precision temperature photometric detector: strictness V (λ), correction, CIE-f1 is less than 0.015.

Luminosity sensitivity: 0.00001 lx, 0.0001 lx, 0.001 lx (optional)

Precision: 0.1 °

Angle resolution: 0.002 °

The maximum specification of the testing lamps:

1) power source: AC/DC 600 V /10 Ax 6

2) weight:50 kg

3) size:1.4 mx1.6 m

Wireless photometric detector can compensate the light wave in the process o measuring

The U.S. Government issued her LED test standards IESNA-LM-79-08. This approved method is a guide developed for the measurement of Solid State Lighting (SSL) products such as LED Street Light, LED Flood Light, LED Down Light, LED Ceiling Light, LED Par Light, LED Tube, LED Module and so on. The most of LED fixtures manufactory use the Integrating Sphere to do the color and photo parameters test. But considering to the SSL’s feature is not like a light source, it requests a goniophotometer to do the test. According to CIE121-1996, the LSG-1800 is recommend.
