LED electrical power over duty cycle (PWM). a. Power recording of a 4 LED system using the TLC5947 (solid lines) and their expected brightness if directly controlled by a microcontroller (dashed lines). All LEDs have been set up to the same power (40 nW), with equal maximal intensity values in the Arduino code (c.f. 6.3). b. as a. but with LEDs set up at different maximal intensities in the Arduino code. Here the linearity of the LED intensity output remains constant. |
