1. An ambient lighting luminaire comprising:
an emergency egress light module;
a housing configured to be positioned above a designated egress path, the housing includes
a first receptacle configured to receive and couple the emergency egress light module thereto, and, under a condition the emergency egress light module is coupled to the first receptacle, the emergency egress light module is configured to rotate horizontally about a vertical axis thereof to align a center beam of the emergency egress light module in proximity to a central longitudinal axis of the designated path of egress below; and
a second receptacle configured to receive and couple an ambient light source thereto;
a primary building power source interface configured to power the ambient lighting source;
a secondary power source interface configured to controllably power the emergency egress light module; and
a power management module configured to electrically couple the secondary power source interface to power the emergency egress lighting light module under a condition that the primary building power of the ambient lighting luminaire is interrupted, wherein
the designated egress path is illuminated to form an illuminated path of egress during operation of the emergency egress light module, and
the emergency egress light module includes a dedicated optical lens covering and is configured to retain at least one lamp, the dedicated optical lens of the emergency egress light module providing directionality to light that passes therethrough.
