The lens is especially designed to intercept 100% of the flux emitted by the LED and control it with minimum dispersion so as to ensure more than 90% effciency. The lens is the primary optical system that collects and redirects the flux without intercepting the geometry of the cell in which it is inserted, thus avoiding a deterioration in performance in terms of quantity and quality of light emission.
The small cells (louvres), in which the LEDs and lenses are inserted, act only as screens to avoid direct viewing of the LED from certain angles but do not affect the flux emitted, leaving a clean, pure light, whose characteristics are de$ned solely by the primary optics.
