We develop luminaires and other types of lighting that are absolutely effective. Light should only be used where it is needed – meaning not all over the place and thus wastefully throughout the complete room.
The effectiveness of a lighting installation considers the light in its application and is defined by the precision of the luminaires used. It is distinct from efficiency as an indicator of the pure energy conversion from electricity to light. The high efficiency of a luminaire alone, expressed in lumens per watt (lm/W), does not by itself make it an ideal tool for sustainable lighting concepts. ERCO considers both metrics within product development: Efficiency through the use of the best LEDs and in-house developed operating electronics for especially low energy consumption. Coupled with effectiveness from high-precision photometric systems also developed by us. The crucial factor here is the quantity of light reaching the surface to be illuminated for a given connected load – i.e. the ratio of illuminance to connected load in lux per watt (lx/W).
To make an efficient luminaire into a luminaire that is effective in its application, precise, dedicated optical systems are needed that direct the light precisely onto the target surface without light spill. Only in this way is it possible to implement effective zonal lighting concepts that, in contrast to normal planar lighting, only use light where human perception requires it. The lighting technology of almost all our luminaires is based on the principle of projecting the light via lenses. This makes them up to 20% more effective than conventional luminaires with reflector technology.
