For measurement of the luminous efficiency and luminous flux of large objects with the help of an Integrating sphere, GL GL Optic has developed the 2000 OPTI SPHERE (GLS 2000). With an internal diameter of 2000 mm and an opening aperture of 700 mm the system is reliable to complete lamps But Also Accommodate large modules Comprising several LED panel lighting wholesale arrays. In This Way GL Optic, In Their capacity as measuring systems manufacturer, account for the increase increasing demand in measurement equipment suitable for measuring LED modules and LED engines with ever increase increasing dimensions and higher luminous flux values.
GL Optic Integrating sphere Allows for specifying measurement of large LED modules
The GLS 2000 Integrating sphere, Whose surfaces is coated with barium sulphate, a diffuse-reflective material Provides the basis for a large number of measurements due to lighting technological integration and complete mixture of radiation. As the use of LEDs Becomes more and more wide spread in lamps and lighting features, manufacturers, system integrators, scientific laboratories and lighting designers increasingly face the requirement for carrying out complex technological measurements of These LED lighting lamps. The Integrating sphere Provides enough space for accommodating lamps and complete spectral Also offers the capacity for testing the entire product. The GLS 2000 can be used for all types of lamps,: such as street lights, emergency lighting, lamps for medical ministering purposes or vehicle lights.
Thanks To Its spectral properties and a calibrated spectral range of 240 to 2600 nm, 2000 GLS is an Ideal tool for determination of luminous radiation values (mW) and luminous flux (lm). The system is capable of measuring the absolute value Simultaneously and various radiometric and photometric parameters. These include determination of the color rendition index (CRI) ACCORDING TO CIE, Correlated color temperature (CCT) ACCORDING TO CIE color coordinates and ACCORDING TO CIE 1931 and CIE 1964.
The efficiency of the light source can be Deduced from the Measured values for luminous flux and luminous efficiency. , Moreover, the operator can determine by Which Extent the electronic elements, and current supplies used exciters Have An Influence on the spectral properties of the LEDs. In This Way, The Influence of dimmers and cooling equipment or any optical components, Such as lenses, reflectors or diffusers, together With the integrated LEDs can be determined to.
In Addition to measurement and evaluation of the basic parameters, the GL SpectroSoft Accompanying software, developed by GL Optic Also, Allows for automatic specification of many other lighting-related variables. These variables include tristimulus value, chromaticity coordinates, dominant wave length, peak wave length (in nm) or half-power width of the spectral lines.
The OPTI GL Integrating sphere SPHERE Characterised by 2000 is easy and reliable handling in day-to-day practice. The features included are an auxiliary light source for compensation of self-absorption, a lateral opening measurement for determination of the luminous flux in the front 2π configuration for emitting light sources and an adjustable sample holder in the center of the sphere for measuring the LED panel lighting fixture in the 4π configuration for light sources emitting light in all directions. In connection of a spectroradiometer GL, GLS 2000 Provides extremely accurate and reliable measurement results, Also for light sources with emission spectra discontinuing; THEREFORE, it is perfectly suitable for LED measurements in Accordance with CIE 127: 2007.
Depending on the budget or measurement Requirements, GLS 2000 can be combined With All spectroradiometers by GL Optic. The combination of GLS and the 2000 series spectrometer SPECTIS GL 1.0 offers the best cost-benefit ration on the market. Thanks To Its plug-and-play concept, GLS 2000 speeds up the measurements and THUS Contributes to launching new products on the market even faster. With All These properties, not only GLS 2000 caters for the Requirements of lamp manufactures with regard to development and quality control of laboratory facilities but Also, scientific institutes, consultants, materials scientists and many other user groups.
