A few innovations
Lighting Systems based on LEDs LED components

Since 2015, innovations in LED chips have become increasingly rare.

Although in 2017, Cree announced XLamp XP-G3 Royal Blue, an LED with an overall energy efficiency of 81% , LED performance is stabilizing. So, when it comes to the evolution of luminous efficacy of white phosphor LEDs (pc-LEDs), the main limitation is the efficiency of the phosphor conversion. Today, for a luminophore at 3,000 K and CRI 80, the theoretical limit is around 265 lm · W ^–1 , and the theoretical limit for a mixture of...
