“…Its use today is not so advantageous in all applications, but only in specific situations where the particular characteristics of the LEDs (small size, light coloured or dynamic) are really useful. Specific areas of virtuous application of these new lamps can be identified in two broad categories, relating to the creation of performance luminaries in a position to communicate with right control systems for the management of lighting contributions and of special optical system, ad hoc, with high lighting performance and small sizes (Liu, et al, 2009). Concluding, with regard the use of this innovative lighting source, small, efficient and dynamic (colour management, the luminous flux, et.…”
