Abstract
Abstract The invention relates to an improved chemiluminescent lighting construction. The new construction affords a highly substantial increase in light intensity and an increase in the workable temperature range for the light reaction, with a correspondingly small increase in material and dimensionality over prior constructions. The construction contemplates disposing a plurality of light producing layered elements within a transparent or translucent encapsulating envelope. The elements are separated by mesh-fabric spacers which allow an activating fluid to flow through the spacers to activate a chemiluminescent substance contained within the layered elements and thereby cause the layered elements to luminesce.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
92 words
A chemiluminescent lighting construction comprising: a plurality of light generating and light transmitting layered elements containing a chemiluminescent substance designed to luminesce upon contact with an activating fluid; light-transmitting fluid pervious spacers respectively disposed between the individual layered elements for providing separation between said layered elements and for allowing said activating fluid to pass therethrough to said layered elements; a sealed light transmitting envelope encapsulating said layered elements with spacers therebetween; and means for admitting the activating fluid to said envelope to cause the chemiluminescent substance within the layered elements to luminesce.
Claim 2
Dependent Claim
92 words
A chemiluminescent lighting construction comprising: a plurality of light generating and light transmitting layered elements containing a chemiluminescent substance designed to luminesce upon contact with an activating fluid; light-transmitting fluid pervious spacers respectively disposed between the individual layered elements for providing separation between said layered elements and for allowing said activating fluid to pass therethrough to said layered elements; a sealed light transmitting envelope encapsulating said layered elements with spacers therebetween; and means for admitting the activating fluid to said envelope to cause the chemiluminescent substance within the layered elements to luminesce.
Claim 3
Dependent Claim
38 words
The chemiluminescent lighting construction of claim 1, wherein the spacers are of a mesh construction for allowing the activating fluid to pass through said spacers to the layered elements and contact the chemiluminescent substance causing it to luminesce.
Claim 4
Dependent Claim
45 words
The chemiluminescent lighting construction of claim 1, further comprising: a light-transmitting non-adherent element disposed between the layered elements and the encapsulating envelope to provide a non-adhering effect between said layered elements and the encapsulating envelope, whereby the layered elements separate from the envelope upon inflation.
Claim 5
Dependent Claim
16 words
The chemiluminescent lighting construction of claim 1, wherein the chemiluminescent substance is an oxygen activated substance.
Claim 6
Dependent Claim
88 words
The chemiluminescent lighting construction of claim 4, wherein the chemiluminescent substance is a tetrakis (disubstituted-amino) ethylene of the formula: (R2N)2C C(NR2)2 wherein the R''s, which need not be the same, are selected from the group consisting of monovalent alkyl of up to 10 carbons, monovalent cycloalkyl of up to 10 carbons, divalent alkylene joined to an R attached to the same nitrogen to form a 3-5 membered monoaza heterocycle, and divalent alkylene joined to an R attached to the other nitrogen to form a 3-7 membered diaza heterocycle.
Claim 7
Dependent Claim
16 words
The chemiluminescent lighting construction of claim 4, wherein the chemiluminescent substance is in an inert carrier.
Claim 8
Dependent Claim
15 words
The chemiluminescent lighting construction of claim 4, wherein the chemiluminescent substance is tetrakis (dimethyl-amino) ethylene.
Claim 9
Dependent Claim
56 words
The chemiluminescent lighting construction of claim 7, wherein the tetrakis (dimethyl-amino) ethylene is in a mineral oil carrier to form a mixture and the ratio of the volume of the mixture of tetrakis (dimethyl-amino) ethylene and mineral oil to the unit volume of any layered element within the construction falls between the range: 0.5:1 and 3.0:1.
Claim 10
Dependent Claim
14 words
The chemiluminescent lighting construction of claim 1, wherein the envelope is a polyamide film.
Claim 11
Dependent Claim
22 words
The chemiluminescent lighting construction of claim 9, wherein the polyamide film is selected from the class consisting of polycaprolactam, poly(hexamethyleneadipamide), and poly(hexamethylensebacamide).
