Energy saving with LED lighting systems
You can get from 30% up to even 70% savings on energy consumption of LED lighting. This result is obtained by automating the switching on, dimming and switching off of lighting fixtures based on the information detected by motion and ambient light sensors, as well as through the use of any time schedules.
Likewise discontinuously occupied areas will be able to enjoy an important energy benefit if managed through motion sensors, able to limit or switch off the devices when they are not occupied.
Similarly, areas involved in a discontinuous way will enjoy of an important energy benefit if managed by motion sensors that are capable of limiting or turning off devices when they aren’t busy.
In each lighting system it can also be interesting to manage the light level based on time schedules, typically with weekly recurrence.
The estimate of the energy savings that can be obtained using automatic lighting control systems is a fundamental datum to evaluate the return time of the investment. This parameter can be calculated using the European Standard EN15193, which defines the evaluation method of the LENI (Light Energy Numeric Indicator).
