Abstract
The present invention relates to providing an improved dimming driver circuitry, system and a method thereof. The dimming driver circuitry is configured to enable dimming intensity of light generated by one or more light sources, the dimming driver circuitry being connected to a dimmer that provides to it an alternating current (AC) signal. The dimming driver circuitry may in some examples not include a processing unit. Additionally or alternatively, the dimming driver circuitry may in some examples apply amplitude modulation to the output current provided to the one or more light sources. In some of these examples, the dimming driver circuitry may begin to apply at substantially the same time pulse width modulation and amplitude modulation to the output current provided to the one or more light sources. Additionally or alternatively, the dimming driver circuitry may in some examples include at least one linear dimming control pin connected to at least one capacitor and/or resistor configured to fine-tune capacitance and/or resistance.
