A Digital Dimming Color and Intensity Method of Three-channel LED
heating seriously and poor adaptability. Accordingly
a digital dimming method of light source was proposed based on PWM technology
which was divided into eight situations. The limitation of this model was pointed out and the principals of the digital light-source was declared from three aspects:dimming theory
control theory as well as driving theory. In the meanwhile
four representative experiments were showed out. The results show that this method can satisfy most proportion of the mixed light models
and realize the adjustment of color as well as the change of illumination. With the function of trigger control
the above problems can be solved properly
at the same time
postponing aging of light-source and energy saving can be achieve as well.
