Light Control Sensor LSR-02

The BUS Light Control Sensor is used for the exact control of artificial light and daylight. The measured light spectrum corresponds to the lux value V-Lambda curve V(λ). It is available with and without integrated motion sensor and can also control according to presence. The sensor is mounted on the ceiling and measures the reflection of the surface below.

Digital Light Control Sensor for workplace and hall constant light control in 2 basic versions.

 

Variant 1 "Light Sensor with Motion Sensor"

 

Digital Light Sensor with double wavelength evaluation to adjust the measurement brightness to the sensation of the human eye and ultra-­miniaturised motion sensor.

The Light Sensor uses the reflected light measurement method, which delivers the standardised lux value using complex calculation algorithms and keeps it constant in the control method.

The benefits of this technology are the easy installation and commissioning, as well as the compensation of age- and contamination-related influences of the illuminants and luminaires. This ensures that the required standardised illuminance is precisely maintained with optimised energy requirements.
Master-Slave measurement evaluations are available for systems with complex lighting conditions, which guarantee the required brightness even in darker areas. Freely definable setpoints are available to the user, which can be activated as required and constantly regulated by the sensor.
For commissioning and service purposes, emergency and bypass functions are available which allow the lighting to be activated at any brightness. The Light Sensor has 2 further inputs, which can be operated either as a freely programmable input or wired with motion sensors. The internal and optional external motion sensors are freely programmable in the linkage. The parameterisation determines whether the switch-on or only the switch-off is activated, whether a timeframe after switch-off until the next switch-on is desired, with which brightness the system is started and much more.

Functions such as On/Off, central switch-on, central switch-off, enabling BW switch-on function and the interconnection of up to 3 sensors in a control zone are available via BUS linking.

 

The types also differ in the angle of detection of the Light Sensor.
