Integrating Sphere Enables Precise Measurements for Large LED Modules

13 JUNE 2012

The rising popularity of LED light sources is making it more important for manufacturers, system integrators, illumination designers and scientific laboratories to carry out complex measurements for LED lamps, whereby the measuring equipment used must also accommodate LED modules and engines of increasing physical dimensions. GL Optic has responded to this need by deve­loping the GLS 1100 integrating sphere. The GLS 1100 provides the basis for taking a wide variety of photometric measurements and can be used for entire mo­dules and engines. Discussion surrounding the introduction of LED lighting equipment is frequently characterized by the question of energy efficiency, which is determined by quantifying the spectral characteristics of the respective luminous element and comparing them to conventional light sources. Key measurements are those required to assess the luminous flux and radiant power. Spectrally calibrated, the GLS 1100 is the ideal tool for this task and enables absolute measurement of radiant power and its spectral distribution. The absolute value and various photometric parameters can be measured simultaneously and include color coordinates, color temperature and the color rendering index (CRI) determined in accordance with CIE standards.
