WE-EF presents very narrow beam ‘sharp cut-off’ [EES] optics, also for colour mixing and tunable white versions of the FLC200 projector

As a pioneer of LED technology in exterior lighting, the development of LED lens systems is among the core competencies of the WE-EF brand. This technological lead is particularly evident when it comes to special requirements, such as very narrow beam optics for projectors with RGBW/RGBA colour mixing or tunable white technology; these luminaires can be used to create impressive effects, for example to accentuate and model architectural details.

Projectors are indispensable lighting tools for highlighting the fine details of large structures such as the cables of a suspension bridge or the pilasters of an ancient building. Their very narrow beam distributions provide excellent accentuation of such details, also from afar. LED projectors with a fixed single colour temperature are ideal for realising such distributions with beam angles of less than 5° – for example, with the symmetric, very narrow beam, ‘sharp cut-off’ [EES] optics that are also used in the WE-EF FLC200 series. Realising such very narrow beam distributions with colour mixing or tunable white projectors presents engineers with a very special challenge – due to the extremely focused beam, special attention must be paid to the quality of the colour mixing, for example to prevent flecks of colour, coloured edges and shadows.

WE-EF has now succeeded in solving this problem, underlining the company’s expertise in lighting technology. The FLC240-CC and FLC260-CC projectors with infinitely variable RGBW/RGBA colour mixing and the FLC240-TW and FLC260-TW projectors with tunable white are now also available with symmetric, very narrow beam, ‘sharp cut-off’ [EES] optics. To achieve this, the WE-EF lighting engineers not only modified the lenses, they also modified the entire system consisting of a diffuser, lenses and LED modules in a very specific arrangement – balancing perfectly the requirements of colour mixing, beam angle and efficiency. The light quality achieved, especially with regard to the colour mixing, corresponds as always to the usual high WE-EF standard. Accessories inside the housing, such as the linear spread lens or the honeycomb louvre, allow perfect adaptation to specific lighting situations.
