6.5
Driver efficiency at nominal load
The LED driver efficiency is up to 89%.
Figure 15. Efficiency vs. AC line voltage at nominal load
Efficiency at Japanese range is around 87% and increases to 88% at European voltage.
6.6
LED driver performance varying the number of LEDs
The performance of the LED driver has been collected varying the LED number and as
consequence the string voltage drops after a thermal warm-up (T = 1 h). In Table 2 are
shown the descriptions of the loads applied and corresponding to a total voltage drop after
a warm-up:
