    摘要： An emergency light includes a lighting module configured for emitting lights, an input unit configured for receiving a power supply voltage from a home power supply, a normal driving module connected to the input unit to receive the power supply voltage and configured to output a first driving signal to drive the lighting module emit lights when the home power supply is normal; and an emergency control and battery module connected to the two input terminals and the lighting module. The emergency control and battery module is configured for detecting the alternating voltage of the input unit and a resistance value between the two input terminals to determine whether the home power supply failure occurs. When the home power supply failure occurs, the emergency control and battery module provides a second driving signal to drive the lighting module emit lights.

    摘要： An emergency luminaire includes an emergency luminaire light source to emit emergency illumination lighting. The emergency luminaire also includes an emergency luminaire power supply configured to be driven by an emergency power line. The emergency luminaire further includes emergency luminaire programming, wherein execution of the emergency luminaire programming configures the emergency luminaire to implement the following functions. The emergency luminaire tracks an active message gap time. In response to receiving a normal power active message from a respective member device of a plurality of member devices of a lighting control group before the tracked active message gap time exceeds an active message timeout, the emergency luminaire resets the active message gap time. In response to the tracked active message gap time exceeding the active message timeout, the emergency luminaire enters an emergency mode (EM) active state by controlling the emergency luminaire light source to emit the emergency illumination lighting.

    摘要： The present disclosure provides an LED straight light including a light tube with two pins at both ends, an LED installed in the light tube and a driving circuit. The driving circuit includes a mains branch and a signal branch. The mains branch is coupled to the pins at one end of the light tube for transmitting power to the LED for power supply. The signal branch is coupled to the pins at the other end of the light tube for transmitting external driving signals to control the on/off of the mains branch. The LED straight light of the present disclosure is powered by two ends, one of the two ends supplies power to the LED through the mains branch, and the other end receives driving signals to control the on/off of the mains branch.

    摘要： The subject disclosure relates to solutions for testing lighting systems and in particular, for verifying lighting system operability in the event of a power failure. A process of the disclosed technology can include steps for receiving an interrupt command, toggling an interrupt relay in response to the interrupt command, and measuring one or more lighting characteristics of the lighting array to determine if the second power supply can power the lighting array. Systems and machine-readable media are also provided.

    摘要： Unsafe restoration of normal lighting is prevented using a reset control communicating with an emergency condition detector and emergency lighting controller in a lighting system. The reset control can be integrated into other system components, like the emergency condition detector, or retrofit into an existing lighting system and configured to work with different types of emergency condition detectors and lighting controllers.
