Energy efficiency can look as good as this
These days, outdoor lights with integrated sensor technology are part and parcel of contemporary lighting planning. These intelligent lights combine the greatest possible energy savings with maximum convenience and enhanced security throughout the building.
SensorLights from STEINEL are just as quick to install as conventional lights and are available in many attractive designs and configurations. This is where STEINEL innovations, like the mini-sensor, permit design solutions with perfectly integrated IR-System, improved detection properties and optimum user convenience.
All benefits at a glance:
Light 'ON' and 'OFF' ...automatically
How does an infrared motion detector work?
Any object with a temperature that lies above absolute zero (-273° C) gives off electromagnetic radiation. Given the temperature range of the human body, this radiation lies in the infrared portion of the spectrum.
Passive infrared (PIR) motion detectors use this fact. These units are equipped with highly sensitive infrared detectors that respond to the slightest fluctuation in the heat they detect by changing their voltage output. The area covered is divided up into active and passive zones by segment lenses. The sensor perceives any movement by a person or warm object across a zone boundary as a fluctuation in heat radiation and emits a signal. This signal is used for controlling light or other electrical loads.
STEINEL sensors generally provide a max. reach of 12 m that may be shorter walking in a radial direction.
Coverage angles of multi-lenses
As a result of their wide coverage angles of 180° to 360°, STEINEL sensors with multi-lenses are also suitable for keeping large areas under perfect surveillance.
Aperture angles of multi-lenses
Depending on the model, multilenses come with an aperture angle of between 90° and 180° with precision coverage of the sneak-by zone.
All sensors come with shrouds that can be cut to size for limiting detection zones (e.g. next to neighbouring property / roads).
Photoelectric lighting controllers measure ambient brightness to prevent lights from being switched 'ON' in broad daylight. A control dial is used to set the brightness threshold at which the lightswitching signal is released.
All STEINEL sensors and SensorLights are equipped with a timer that makes sure the light stays switched 'ON' for a selectable period of time even after a temporary movement occurs in the detection zone.
If light is required at full power over a prolonged period, many STEINEL sensors and SensorLights can be set to stay 'ON' all the time (4 h) by actuating the power switch twice in brief succession.
STEINEL Watt-o-matic provides permanent night-time lighting with a basic brightness that can be set to between 0 – 50%. When movement is detected, the light switches to full power for the time selected.
Soft light start and soft end
The innovative soft light start function from STEINEL gently and elegantly takes light bulbs to full power and turns them 'OFF' in the same way too. This is kind on the eyes and prolongs bulb life.
Hi-tech in forward-pointing design
The facade, garden and driveway say everything about a house. Lighting plays a crucial part in shaping this impression. Many customers are particularly fastidious when it comes to choosing suitable lights. The unavoidable sensor lens in PIR systems is often felt to spoil their look.This why STEINEL was quick to search for ways of integrating the sensor system in the design of a light and keep it out of sight as far as possible without having to compromise on functionality. Development of the STEINEL mini-sensors was a milestone in this direction. The system is so small that is perfectly integrates in the design of the light.
This miniaturisation is made possible by combining an extremely efficient sensor chip with precision mirror optics that take in the infrared radiation through a narrow, hardly visible ring window within a 360° radius and guide it onto the chip.
The module also accommodates the entire light control system that uses a microchip. The programmes provided can be conveniently set at buttons with the module removed.
The new operating concept
To permit rapid, intuitive adjustability of the sensor electronics to individual user needs, the entire sensor module can be taken out of the light, set in your own time, put back in again and made theftproof.
While settings are being made, the light switches itself 'ON' as soon as the sensor is removed. This is practical at twilight or during the night. All of the information you need to know is printed in the sensor module itself, obviating the need for any operating instructions.
Soft light start and soft end
The innovative soft light start function from STEINEL gently and elegantly takes light bulbs to 100 % output and switches them down to 0 % output in the same way too. This not only looks good, it prolongs bulb life.
Basic brightness function
All STEINEL lights with the mini -sensor can be set to operate with a basic brightness of approx. 25% (Watt-o-matic) until midnight (programme 1) or right through the night (programme 2). When movement is detected, the light switches to full power for the time selected.
