Abstract: A light fixture includes a driver for driving a light engine based on control signals received from a controller coupled to the driver. The driver is further connected to an AC power source and is configured for detecting a power loss from the AC power source and generating a power loss signal. Upon detecting the power loss, the driver sends the power loss signal to the controller. Based on the power loss signal, the controller sends an emergency egress mode control signal to the driver which drives the light engine in the emergency egress mode, i.e. at its full intensity for an emergency time period. Upon expiration of the emergency time period or upon the recovery of the AC power, the controller exits the emergency egress mode by sending a normal control signal to the driver.

Abstract: A lighting system for and method of commissioning LED light fixtures is disclosed. The LED light fixtures include a controller unit that is programmed with lighting firmware and an on-board 5 light sensor that is responsive to visible light signals from a light source. In operation, the light sensor is irradiated visible light signals and/or visible light sequences that instruct the LED light fixture via the controller unit to join a group, be locked into a group, run lighting programs and/or become un-locked from a group.
