Large Scale Measurement Systems For LED Module And SSL Light Source

The LGS 1000 is ideal for the analysis of angle-dependent spatial radiation characteristics of large LED modules, solid-state lighting (SSL) products and conventional lamps and luminaires. It can be operated together with a photometer as a conventional goniophotometer or with a spectrometer as a high-quality goniospectroradiometer. This allows all important performance characteristics such as luminous intensity distribution curves, luminous flux, color coordinates and even color rendering index to be measured with maximum precision.

The LGS-1000 Goniophotometer is a high-precision instrument designed by Instrument Systems for measuring the light distribution properties of lamps, luminaires, and other lighting products. It is a versatile and reliable tool that enables lighting manufacturers to evaluate and optimize the performance of their products.

The LGS-1000 Goniophotometer measures the angular distribution of light emitted by a source, enabling users to analyze key parameters such as luminous flux, luminous intensity, and color. The instrument is capable of measuring light at angles ranging from -165 to +165 degrees at y-axis and -90 to +270 degrees at C-axis, with a resolution of 0.01 degrees.

Instrument Systems LGS 1000 goniophotometer accommodates samples up to a diameter of 2 m and a maximum weight of 50 kg. The sample table measures 210 mm x 210 mm and can easily be reached using accessible steps on the goniometer. It is fitted with 3 x 3 size 6 grooves. Different thread inserts and fitting bushes facilitate  reproducible and safe fixing of the test specimen. This allows easy and quick mounting of customer-specific sample holders.

The goniophotometer system from Instrument Systems includes a comprehensive range of  accessories such as the luminous flux integrator which measures test objects up to a diameter of 200 mm in their required burning position in conformance with standards CIE S 025, EN 13032-4 and IES LM-79-2008. An additional burning position correction enables the characterization of larger probes. 

Overall, the LGS-1000 Goniophotometer is a powerful and reliable tool for lighting manufacturers and researchers, providing precise and accurate measurements of light distribution properties. Its flexibility, accuracy, and ease of use make it a valuable tool for a wide range of applications in the lighting industry.
