A range of infrared controlled luminaires has been developed by Scandinavian group, Ensto Oy. These will allow electrical installersgreater flexibility in lighting control of compact fluorescent lamps while offering energy savings of up to 80 per cent according to the company.

One or more lights can be controlled by a single luminaire containing a passive infrared detector (PIR). Lights can be switched on automatically when the detector picks up movement in the area it covers, unless available daylight exceeds the level set on the light-sensitive switch. Lights go out automatically when movement has ceased for a pre-set interval.These luminaires require no separate control wiring or additional switches.

Energy saving
Peter Broberg, Export Manager at Ensto, says that, in some applications, energy savings of up 80 per cent has been achieved compared to conventional lighting solutions. In addition, PIR technology can also be used to switch lights from a constant low level lighting to a more intense level when movement is detected. This hands-free operation provides additional features of comfort and safety in building environments.
Potential applications include lighting for corridors, stairways, storage facilities, basements and toilets in commercial buildings and private dwellings. In addition, the PIR luminaires are available in a variety of fittings to give flexible design and mounting alternatives. They are also designed to meet electrical requirements in individual countries throughout Europe.PIR versions are available in the company's AVR 66,AVD 74 and AVR 1 series of luminaires.
Ensto is a Scandinavian company with a 40 year history in the electrical market with a product range from lighting fittings to components for the electronic, electrical and electricity transmission industries.
Products are sold in 50 countries world-wide with its major markets in Europe. Its turnover in 1998 was FIM 1,127 m (Euro 190m), and has around 1,900 employees.
