  • Dimming control of lighting modules
    Patent number: 10728973
    Abstract: A lighting fixture includes a voltage source circuit and a first light module comprising a first current source circuit and a first light emitting diode (LED) light source. The lighting fixture further includes a second light module that includes a second current source circuit and a second LED light source. The voltage source circuit is configured to provide a voltage source output voltage to the first current source circuit and to the second current source circuit. The first current source circuit is configured to provide a first current to the first LED light source. The second current source circuit is configured to provide a second current to the second LED light source. A voltage level of the voltage source output voltage depends on a waveform of a line dimmer output voltage that is provided to the voltage source circuit.
