Building egress lighting apparatus method and system with direction designator projection features

A building safety and security apparatus comprising:

• a support plate;
• a luminaire housing coupled to the support plate, the support plate retains a power supply, a photocell, a switch, and a processor that includes programmable circuitry;
• an egress light module that includes a lamp and a linear pattern optical lens disposed over the lamp and configured to direct light emitted by the lamp in an elongated linear pattern;
• a receptacle coupled to the luminaire housing and configured to convey at least one of power or a signal, the egress light module is electromechanically coupled to the receptacle, and horizontally positioned and rotatable about a vertical axis thereof, wherein
• power to said egress light module is switchably conveyed through the switch, and the photocell is configured to monitor a light level intensity reflected from a floor below the building safety and security apparatus, and
• the programmable circuitry of the processor is configured to receive an input from the photocell indicative of the light level intensity and control a state of the switch based on at least one pre-determined threshold, such that said processor controls the switch to:
• (a) turn on the egress light module when the monitored light level intensity falls below a predetermined low light level threshold, and (b) turn off the egress light module when the light level intensity exceeds a predetermined high light level threshold.

A building safety and security apparatus comprising:

• a support plate configured to couple to a support structure above;
• a housing coupled to said support plate;
• a power supply coupled to at least one of the housing or the support plate;
• a processor coupled to at least one of said housing or said support plate, said processor having programmable circuitry and being addressable;
• a wireless communication transceiver coupled to the processor and configured for communication with at least one remote client;
• an egress light module coupled to a bottom surface of the housing and configured to illuminate a path of egress below the building safety and security apparatus, the egress light module includes
• a lamp and a linear pattern optical lens disposed over said lamp that directs light from said lamp in a predetermined direction and in a linear light pattern, and
• a receptacle coupled to the housing that is configured to provide at least one of power or signal connectivity to the egress light module and to electromechanically couple the egress light module thereto such that the egress light module is horizontally disposed and rotatable about a vertical axis thereof, wherein
• the programmable circuitry is configured to
• process a wireless signal received via the wireless communication transceiver, the wireless signal being indicative of an environment within communication range of the building safety and security apparatus, and
• generate a visual representation of a space in the communication range based on the processed wireless signal, the generated visual representation showing at least one of an entity or object form, entity or object mobility, or whether an entity or object generates heat relative to local surroundings.
