A new type of outdoor indirect lighting luminaire, which provides an increased downward light output ratio (DLOR) whilst reducing light pollution, has been developed by Thorn:
This new outdoor indirect lighting luminaire range, known as Aviso, incorporates innovative reflector technology to deliver strong aesthetic values and high performance.
High efficiency and ultra-low light pollution:
Indirect fittings project light upwards onto a reflective plate, which in turn directs the light back down again. Thorn's Aviso is said to be a considerable technical advance due to its innovative top plate with Mosaique reflector (patent, pending). Each reflector comprises of 24 tiles, configured together in a choice of arrangements to throw more light towards the longitudinal or transverse direction. Each tile comprises of nine cells and has three layers: a coat of protection paint, a metallised coat and a transparent PMMA skin to protect it. The result is 97% containment of light on the top plate giving better efficiency and ultra-low light pollution, whilst maintaining outstanding visual comfort. The DLOR is around 50% and a typical scheme has a threshold increment (TI) lower than 4%.
The 'rectangular light' projector uses a 70W or 150W ceramic metal halide lamp and connects to the top plate by the luminaire body /arm. There is a choice of two, tiltable arm shapes with a further selection of dedicated columns (3.2m and 5.2m high).
