En fonction de leurs spécifications, certains pilotes de LED peuvent également faciliter la gradation et/ou le séquençage des couleurs. Whether the LED lighting can be dimmed is usually marked on the box. The LED dimming function has the advantages of saving energy, improving the quality of life, improving the efficiency of the light source, etc..
Depending on the type of LED driver we select, their dimming skill can cover the full range. The driver dims the LEDs by either shortening the amount of leading current going through it, or by a method called pulse width modulation (PWM). Most drivers that offer dimming use PWM. This allows dimming without flickering and with usually very little color change in the LEDs.
It is good to note that dimming does not affect an LED’s competence. It also will not have a negative impact on how long it lasts. En fait, dimming can potentially help LEDs last longer as it will reduce the heat it creates when lit.
With color sequencing or changing, many times an LED string or product may have LEDs of different colors. En fait, many times a “blanc” colored LED lamp is actually not using “blanc” colored LEDs. Plutôt, it uses different colors that when shown together produce white light. So with a driver with this capability, you would be able to control the
