Abstract
An automatic device for providing chemiluminescent light from a chemical reaction of suitable compounds in the presence of a fluorescent compound, said device being an emergency source of illumination upon failure of public utility service.
Claims9
A device for displaying emergency lighting comprising a base plate, an extension plate extending vertically from and affixed at one end to said base plate, pivot means attached to the other end of said extension plate, a metallic plate affixed at one end by said pivot means to said extension plate to allow said metallic plate to swing about said pivot means, an elongated rigid rod affixed at one end to the other end of said metallic plate opposite said pivot means, clamping means affixed to the other end of said elongated rigid rod, bias means affixed at one end to said base plate and positioned on said base plate to contact said metallic plate when said metallic plate is pivoted about said pivot means to aligned said rigid rod substantially parallel with said base plate, an electromagnetic force means affixed at one end to said base plate adjacent said bias means and disposed to contact said metallic plate when said metallic plate is pivoted about said pivot means to align said elongated rigid rod substantially parallel to said base plate, electrical power means connected to said electromagnetic force means to create an electromagnetic force so that when said metallic plate contacts said electromagnetic force means the bias means is compressed, a chemiluminescent light device comprising at least two elongated containers each container sealed on both ends and each containing a chemical component of a multicomponent chemiluminescent system, said containers comprising a translucent outer container and at least one rigid frangible inner container located within said outer container, said outer container held in the center by said clamping means, a pair of restraining means loosely encompassing each end of said outer container and affixed to said base plate so that when the electrical power fails the compressed bias means will press against said metallic plate bending said flexible outer container sufficiently to break the inner frangible container and cause the chemical components to become admixed after the ends of the outer container slip free of said restraining means to display the chemical lighting device in a position vertical to said base plate.
