Moving Mirror Goniophotometer Introduction

Lisun LSG-2000 Moving Mirror Goniophotometer System adapts the solution of rotating mirror in the center, it is widely applied in road lamp, room lamp, spot lights, stage lights, Mining lamp, Automobile lamp, traffic signal lamp and LED lamp etc. all kinds of luminaries for light distribution performance(light distribution curve) measurement, it can also test total flux, luminaries efficiency for all types of lighting sources. It can realize CIEA-α，CIEB-β，CIEC-γ measurement solution with different software. The test result can be directly used as the input data of the international lighting design software, and comply with the requirements of CIE, IESNA and other international and domestic standards.

Lisun LSG-2000 Moving Mirror Goniophotometer System can test spatial luminous intensity distribution, luminance intensity data, zonal luminance flux, luminance efficiency, coefficient of Utilization, luminance limitation curves glare, maximum ratio of distance to height, efficient luminescence angle, upper luminous flux, lower luminous flux, available average illuminance curve, Isocandela diagrams etc. photometry parameters, and voltage, current, power, power factor etc. electrical parameters.

Accuracy of angle: Class A.f1’<3% (Standard Class) or Class L.f1’<1.5%.

C angle: 1) Rotating Range: 0°~360°; 2) Angle accuracy: 0.1°; 3) Angular Resolution: 0.001°.

γ angle: 1) Rotating Range: -180°～180°; 2) Angle accuracy: 0.1°; 3) Angular Resolution: 0.001°.

This system has 3 rotating axis. Main axis drives the reflective mirror rotate around the center point, reflect the light of the lamp to the detector. At the same time, auxiliary axis reverse rotates synchronously, always keeps the lamp bracket in the vertical position, to ensure the test lamp in normal ignite position in the measurement process, and achieve the lamp in the main axis direction measurement.

Lisun LSG-2000 Moving Mirror Goniophotometer System can work with a CCD spectroradiometer with USB interface to test spatial CCT distribution and other spectral color parameters. The rotation motor is from Japan MITSUBISHI MOTORS to make the system rotate very smoothly and stably. And it uses Germanic Angle decode system to ensure the system accuracy. It adapts RS-232 standard interface, it can be connected to PC.

Lisun LSG-2000 Moving Mirror Goniophotometer System is widely applied to Luminaries manufacturing enterprise and lab, such as Sharp Electronics in Memphis TN(USA), CS TECH MEXICO, S.A. DE C.V. (Mexico), DORADO Praha s.r.o. (Poland) etc. The reason why Lisun can win some many customers is because we always practice the motto of right products, right price and right service. Lisun will continue feedback good quality products and superior service in the feature.
