Emergency Lighting Optics
The provision of Emergency lighting is required in public spaces for both large areas and corridors. Conventional circular distributions of light from luminaires are inefficient at filling both types of area. Polymer Optics has developed optics to efficiently collect the light output from a Lambertian output LED and produce both rectangular and square beams with uniform illuminance optimized for this application. Our 290 optic is designed for corridor emergency lighting but also has other uses such as high bay lighting for walkways. Mounted at 2.5m it produces a 2m x 10m evenly illuminated rectangle of light that allows the minimum 1 Lux emergency lighting requirement for corridors to be met using a single LED that outputs just 25 lumens of light. Our 532, 535 & 536 Optics produce square areas of light with widths of 2.4x, 3.5x and 6.6x the mounting height respectively allowing large areas to be efficiently lit with square patterns of ceiling mounted luminaires.
