  • Emergency lighting systems and methods for solid state lighting apparatus
    Patent number: 9835691
    Abstract: An emergency lighting module for providing emergency power to a solid state luminaire. The emergency lighting module includes a first input configured to receive a DC input voltage from the solid state luminaire, a second input configured to receive a status signal indicative of the status of an AC line voltage, and a first output configured to supply a DC output voltage to the solid state luminaire. The emergency lighting module is configured to supply the DC output voltage to the solid state luminaire in response to a reduction of the AC line voltage.
    Type: Grant

  • Dimming control for emergency lighting systems
    Patent number: 9560703
    Abstract: An emergency lighting module for providing emergency power to a solid state luminaire includes a microcontroller, and a detector coupled to the microcontroller and configured to detect a status signal indicative of a status of an AC line voltage, the emergency lighting module is configured to output a dimming control signal to the solid state luminaire in response to a reduction of the AC line voltage. The microcontroller is further configured to output a select signal to the solid state luminaire to cause the solid state luminaire to dim in accordance with the dimming control signal when the dimming control signal is output.
