An exit sign comprising a housing and a plurality of red and green
color LEDs having the capability of being selectively activated
to produce either red light or green light. The plurality of LEDs
are mounted in a mutual lighting association in the housing. A switch
is manually operable to selectively activate the plurality of red
color LEDs to produce the red light and in the alternative, to selectively
activate of the plurality of the green color LEDs to produce the
green light. Means for passing light from the selected red light
or selected green light in the form of indicia symbolizing an exit
enables viewing by an observer, such means include a stencil having
four independent letters forming the word EXIT. DC circuitry is
in operative electrical connection with the plurality of LEDs. A
source of DC electrical power activates the DC circuitry. The plurality
of LEDs can be monochrome red LEDs and monochrome green LEDs or
in the alternative, the plurality of LEDs can be bicolor LEDs having
the capability of producing red light or green light. Red light
and green light can be simultaneously emitted so as to produce yellow
light. An emergency power backup battery is connected to the plurality
of color LEDS. Means for producing emergency light is optional.
An emergency exit sign includes a support assembly which permits
rotation of lighting heads, about an upright axis, through an angle
greater than 180.degree.. A freely rotatable joint element is used
to maintain the lighting heads, in cooperation with mating facets,
in various positions without the need for mechanical fasteners.
The lighting heads are also attached to a snap connector which,
enables the lighting head to be shifted about an arcuate axis, as
well as rotated about a still further axis which is substantially
perpendicular to the upright axis.
An emergency exit sign is incorporated directly into the floor
adjacent an emergency exit door. The emergency exit sign includes
visual and tactile properties that allow the sign to be read on
a day to day basis by those walking through the doorway. The tactile
properties of the sign also allow the sign to be read by those on
the floor in an emergency situation such as when the room or hallway
is filled with smoke. The tactile properties of the sign may also
be used by those trying to find the doorway in a dark room. Further,
the tactile properties of the sign are used on a day to day basis
as people walk over the sign to reinforce the person's memory of
the location of the emergency exit door.
