Light Colour/Brightness Sensor LS-04

The calibrateable Colour/Light Sensor for the ISYGLT system can be used as an outdoor Light Sensor or as an indoor sensor. Many different curves and value queries are available to use the sensor for a wide range of applications.

A special application is the regulation of light precisely to the desired light colour, e.g. in offices, schools, industry (e.g. control rooms) or museums. The direct measurement also includes daylight.

Another interesting application for biologically effective lighting control is the measurement of the outside light and transmission of the exact value into the interior.

Quick Facts

  • Colour temperature sensor
  • CCT value measurement
  • Luxmeter (V-Lambda)
  • RAW sensor red, green, blue CLEAR, IR
  • Colour temperature control
  • HCL control
  • Measurement recording for research

The digital Light and Colour Temperature Sensor LS-04 is used to measure brightness and colour temperature and can be used to optimise "Human Centric Lighting" (circadian lighting control) in schools or museums, at workplaces or in private homes. Daylight and artificial light can be evaluated with the sensor. A recording of the measurements is optionally possible very comfortably in connection with the IPMS visualisation. The measured brightness spectrum corresponds to the standardised V-Lambda curve. The colour temperature is output as a CCT value in Kelvin. In addition, information about the X- and Y-CCT coordinates and the raw values of the individual sensor chips can be called up. Thanks to extensive parameter settings, the sensor can be individually adapted to local conditions. The transmission to the master takes place with 1 to 3 digital 16 bit values. Due to its compact design, the sensor can be universally integrated into the architecture.
