Abstract
A rotational emergency egress light module is coupled by a universal receptacle to an ambient lighting luminaire. The rotational emergency egress light module includes a lamp and an optical lens. The optical lens directs light from the lamp in a predetermined direction. The emergency egress light module is configured to rotate such that the direction of the light from the optical lens illuminate a path of egress in a building.
Claims23
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.

A method of operating an ambient lighting luminaire, the method comprising:
- connecting an emergency egress light module to a first receptacle of a luminaire housing installed above a designated egress path;
- controllably powering an ambient light source coupled to a second receptacle of the luminaire housing with power from a primary building power source;
- controllably powering a secondary power source interface of the luminaire housing to a secondary power source;
- rotating the emergency egress light module about its vertical axis to align a center beam of the emergency egress light module in proximity to the central longitudinal axis of the designated path of egress below;
- and
- under a condition the primary building power of the ambient lighting luminaire is interrupted, automatically switching the emergency lighting light module to be electrically powered by the secondary power source and illuminating the path of egress below the ambient lighting luminaire during operation of the emergency egress light module.
