This article presents basic metrological properties of selected integrated color sensor models. The study involved MTCSiCS and MMCS6 sensors, produced by MAZeT. Describes electronic circuits necessary for reading data from the color sensor. The analysis shows the relative characteristics of spectral sensitivity of the detectors, the linearity characteristics of the output signal as well as the useful range.
LED modules emitting a luminous flux, implement near-field luminance distribution or colorimetric distribution depending on emitters location. In the far field there is complete mixing of luminous flux, both in terms of quantity as well as because of distribution color parameters. To achieve these mixing light in a short distance of the LEDs is necessary to use optical elements. The article presents the results of creating light distribution and luminance by using the ring optical elements with truncated outer surfaces.
