MAZeT GmbH Announces an OEM Sensor with Smart Color Control

MAZeT GmbH, a leading provider of Electronic Design and Manufacturing Services, will present their new JENCOLOR color sensor solutions for lighting applications during the trade show "electronica" in Munich from November 13th to 16th at booth 520 in hall A2.

The sensor board MTCS-INT-AB3 is based on two new IC solutions, which are specially developed to solve tasks in LED lighting control - for example: feedback color control of LED light sources. The True Color sensors IC in implemented on the board performs color measurements based on the standard CIE 1931 - the human eye perception. It is possible to directly process the data as XYZ values or within the Lab/Luv color space. The XYZ filters of the sensor show no temperature or aging drift effects and are long-term stable throughout the entire lifecycle of a product.

The on-board signal converter IC MCDC04 consists of an ADC with high bandwidth and I2C output. The IC processes via charge-balance method and converts lowest photocurrents at high accuracy (16 bit). Its full-scale range can be customized to the specific application forehand and during operation via programming. Therefore it is possible to realize a sensitivity of 20fA/LSB at a dynamic of 1 to 1.000.000. The IC is temperature compensated and features the possibility of external measurement synchronization.

The board is an ideal OEM color sensor solution within the Luv/Lab color space with simple implementation based on the two modules on the board in addition with a power supply and I2C interface. Together with a µC or FPGA it is possible to directly implement the XYZ sensor values within algorithms for measurement or control tasks at an accuracy of Delta u'v' <0,003. Therefore the OEM sensor is an ideal addition to all applications that require a high accuracy and stability of colors, even in harsh environmental conditions like temperature shifts. Examples are the calibration of cabin lights in airplanes, or the color management of backlights in displays or video walls.
