Spotlights, floodlights and wallwashers are flexible and efficient lighting tools for the effective presentation of art. The quality of lighting technology is not only important for the precise distribution of light and a qualitative art experience, but also for the long-term cost-efficiency of the lighting installation.
Luminaires are efficient if the energy deployed reaches the target plane in the form of light. For this reason ERCO uses individually arranged LEDs and an in-house developed lens system consisting of collimators and interchangeable Spherolit lenses. Conventional optical systems however consist of chip-on-board (COB) LED modules and a reflector. Here several LEDs are arranged below a phosphor layer and form a large luminous surface. Not all light beams can be directed with this construction – this creates spill light (the red lines). The result - the optical system has less efficiency and precision.
