Exit sign illuminated by selective color leds

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.

Exit sign with rotatable lighting heads

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.

Emergency exit sign

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.
