     BACKGROUND OF THE PRESENT INVENTION 
     Field of the Present Invention 
     The present invention relates generally to fluid spray bottles, and, in particular, to lighting features integrated with spray nozzles. 
     Background 
     Spray bottles are well known. Common types include variable spray nozzles, trigger activated pump designs, and aerosol propellant canisters. Different variations exist to improve comfort, ease of use, and a variety of spray patterns. 
     LED lighting is a well-known technology. Different wave lengths of visible light can be used to illuminate chemical substances including those of dangerous or undesirable composition. In additional to common color shades which can be used to change observed contrast, the ultraviolet spectrum of light can particularly be utilized to illuminate contaminants and chemicals invisible to the naked eye. UV lighting is also known to be damaging to harmful bacteria, fungus, and mold under certain conditions. As such, UV lighting can be used not only to illuminate areas of concern, but also to actively sanitize the same areas utilizing exposure to the light. 
     Alternative designs have integrated motorized pumping technologies, as well as ionizing and ozonating technologies to improve cleaning effectiveness. 
     UV lighting has been used separately to illuminate harmful elements of a surface or room. UV lighting has been used in the process of neutralizing harmful properties of these elements as well. 
     Some spray bottles making use of lighting elements are known. U.S. Pat. No. 8,210,395 to Morris discloses a spray dispenser (such as a bottle of perfume) that utilizes small visible light emitters (which may be LEDs) adjacent a nozzle to help a user find the location or direction of the nozzle, but the light has to be visible so as to carry out its function, and further, the light is intended to be on only when the user is searching for the location of the nozzle, and not when actually spraying the fluid. U.S. Patent Publication No. US 2007/0189834 A1 to McKay, SR, discloses a detachable black light unit stored in the body of a sprayer, but is used separately from the spray head itself and thus does not provide the convenience of mechanically linking the direction of the black light emanating from the black light unit with the direction of spray. 
     Thus the continued need exists for improvement in the area of cleaning and sanitizing products, particularly in the area of integrated solutions and development of a symbiotic system

     DETAILED DESCRIPTION 
     As a preliminary matter, it will readily be understood by one having ordinary skill in the relevant art (“Ordinary Artisan”) that the present invention has broad utility and application. Furthermore, any embodiment discussed and identified as being “preferred” is considered to be part of a best mode contemplated for carrying out the present invention. Other embodiments also may be discussed for additional illustrative purposes in providing a full and enabling disclosure of the present invention. As should be understood, any embodiment may incorporate only one or a plurality of the above-disclosed aspects of the invention and may further incorporate only one or a plurality of the above-disclosed features. Moreover, many embodiments, such as adaptations, variations, modifications, and equivalent arrangements, will be implicitly disclosed by the embodiments described herein and fall within the scope of the present invention. 
     Accordingly, while the present invention is described herein in detail in relation to one or more embodiments, it is to be understood that this disclosure is illustrative and exemplary of the present invention, and is made merely for the purposes of providing a full and enabling disclosure of the present invention. The detailed disclosure herein of one or more embodiments is not intended, nor is to be construed, to limit the scope of patent protection afforded the present invention, which scope is to be defined by the claims and the equivalents thereof. It is not intended that the scope of patent protection afforded the present invention be defined by reading into any claim a limitation found herein that does not explicitly appear in the claim itself. 
     Thus, for example, any sequence(s) and/or temporal order of steps of various processes or methods that are described herein are illustrative and not restrictive. Accordingly, it should be understood that, although steps of various processes or methods may be shown and described as being in a sequence or temporal order, the steps of any such processes or methods are not limited to being carried out in any particular sequence or order, absent an indication otherwise. Indeed, the steps in such processes or methods generally may be carried out in various different sequences and orders while still falling within the scope of the present invention. Accordingly, it is intended that the scope of patent protection afforded the present invention is to be defined by the appended claims rather than the description set forth herein. 
     Additionally, it is important to note that each term used herein refers to that which the Ordinary Artisan would understand such term to mean based on the contextual use of such term herein. To the extent that the meaning of a term used herein—as understood by the Ordinary Artisan based on the contextual use of such term—differs in any way from any particular dictionary definition of such term, it is intended that the meaning of the term as understood by the Ordinary Artisan should prevail. 
     Regarding applicability of 35 U.S.C. §112, ¶6, no claim element is intended to be read in accordance with this statutory provision unless the explicit phrase “means for” or “step for” is actually used in such claim element, whereupon this statutory provision is intended to apply in the interpretation of such claim element. 
     Furthermore, it is important to note that, as used herein, “a” and “an” each generally denotes “at least one,” but does not exclude a plurality unless the contextual use dictates otherwise. Thus, reference to “a picnic basket having an apple” describes “a picnic basket having at least one apple” as well as “a picnic basket having apples.” In contrast, reference to “a picnic basket having a single apple” describes “a picnic basket having only one apple.” 
     When used herein to join a list of items, “or” denotes “at least one of the items,” but does not exclude a plurality of items of the list. Thus, reference to “a picnic basket having cheese or crackers” describes “a picnic basket having cheese without crackers,” “a picnic basket having crackers without cheese,” and “a picnic basket having both cheese and crackers.” Finally, when used herein to join a list of items, “and” denotes “all of the items of the list.” Thus, reference to “a picnic basket having cheese and crackers” describes “a picnic basket having cheese, wherein the picnic basket further has crackers,” as well as describes “a picnic basket having crackers, wherein the picnic basket further has cheese.” 
     Referring now to the drawings, in which like numerals represent like components throughout the several views, one or more preferred embodiments of the present invention are next described. The following description of one or more preferred embodiments is merely exemplary in nature and is in no way intended to limit the invention, its implementations, or uses. 
       FIG. 1  is a perspective view of a lighted pressure actuated fluid dispersal system  1000  in accordance with a first preferred embodiment of the present invention; and  FIG. 2  is a side cross-sectional view of the fluid dispersal system  1000  of  FIG. 1 , taken along line  2 . As shown therein and in other illustrations, the system  1000  includes a sprayer head  1100  and a reservoir  1600 , as well as various other elements, including an electrical system  1200 , described below in  FIG. 3 ; an air pressurizing pump system  1300 , described below in  FIG. 4 a    and  FIG. 4 b   ; a fluid distribution system  1400 , described below in  FIG. 5 , and enclosure components  1500 , described below in  FIG. 6 . 
     Referring to  FIG. 1 , the sprayer head  1100  includes a light fairing  1513 , a left housing  1503 , right housing  1524  and the housing contains LED light holes  1145 , and a finger hole  1140 . The sprayer also includes a pump body  1323 , a pump handle  1328 , an indicator  1408 , a turret head  1412 , a fluid valve switch  1416 , a selectable nozzle  1412 , and an electrical switch cover  1215 , all of which connect to internal systems whose parts are illustrated and described in detail below. 
       FIG. 3  is a side cross-sectional view of the electrical system  1200  in the fluid dispersal system  1000  in  FIG. 2 . As shown therein, the electrical system  1200  includes LED illuminators  1209  is powered by a battery cluster  1204 , that may be accessed through a battery door  1207  located on the left side of the sprayer head  1100 . The batteries  1204  connect to battery contacts  1206 . The battery contacts  1206  connect to a circuit-board by wire  1229  then connect to an electrical switch  1214  by wire  1227 . The LED illuminators  1209  are activated when the electrical switch  1214  is operated and the signal is returned by wire  1227 . The user can activate the LED illuminators by pressing the electrical switch cover  1215 , which in turn causes the electrical switch  1214  to move and so completes the electrical circuit between the batteries  1204  and the LED illuminators  1209 . The user may press the electrical switch cover  1215  thus turning on the LED illuminators  1209 , independently of spraying any fluid through the fluid distribution system  1400 . The user may also press the electrical switch cover  1215  simultaneously with the action of spraying the fluid through the fluid distribution system. The simultaneous action will be explained in detail below. 
     In at least some embodiments, the LED illuminators  1209  are UV lights, which have various advantages over lights in visible and other portions of the electromagnetic spectrum. However, some benefits may be realized by illuminators using other than those in the ultraviolet spectrum. 
       FIG. 4 a    is a side cross-sectional view of the fluid dispersal system  1000  of  FIG. 1  showing the air pressurizing pump system  1300  thereof, and  FIG. 4 b    is an exploded isometric view of the pump system  1300  of  FIG. 4 a   . As shown therein, the pump system  1300  includes a pump handle  1328  which is connected to a piston  1301 . The pump system is used to pump air into the reservoir  1600  thus pressurizing the fluid in the reservoir  1600 . The piston  1301  goes into the pump body  1323 . An airtight seal is created between the piston  1301  and the pump body  1323  with a piston seal  1302 . The pump body then connects to a pump valve  1322  which allows the air to enter the reservoir and pressurize the fluid. 
       FIG. 5  is a side cross-sectional view of the fluid system  1400  in the sprayer system in  FIG. 1 . As shown therein, the fluid system  1400  includes a selectable nozzle  1412  that allows the user to choose the type of spray stream and the volume of spray. In this preferred embodiment, the selectable nozzle  1412  contains four different settings. In other preferred embodiments the selectable nozzle  1412  may have less than four settings or more than four settings. In this preferred embodiment the selectable nozzle  1412  is connected to a mode indicator  1408  via an indicator linkage  1417 . The mode indicator  1408  contains writing or an icon to show the specific setting the user has chosen when they turn the selectable nozzle  1412 . In other preferred embodiments a mode indicator  1408 , may not exist. Also, in some embodiments the drawing or words may be placed directly on the selectable nozzle  1412  to indicate the setting. 
     The selectable nozzle  1412  is also connected to a fluid channel  1410  via a channel gasket  1411 . The fluid channel  1410  connects to a valve  1405  and the valve  1405  connects to a dip tube  1420 . The valve  1405  also connects to a lever  1426 , and a spring  1425 . When the lever  1426  pushes up on the spring  1425 , the valve  1405  is opened. In order to open the valve the user must push the fluid valve switch  1416 , causing the lever  1426  to push up on the spring  1425 , thus opening the valve  1405 . 
     When fluid in the reservoir is pressurized by the pump system  1300 , the pressure in the reservoir forces the fluid into the dip tube  1420 . In turn, when the user pushes on the fluid valve switch  1416 , the valve  1405  opens, and the pressure in the system forces fluid into the fluid channel and finally out the selectable nozzle  1412 . In other preferred embodiments the fluid system  1300  may be controlled by a fluid pump instead of a pressurized pump system. 
       FIG. 6  is an exploded isometric view of the enclosure components  1500  of the fluid dispersal system  1000  in  FIG. 2 . As shown herein, the sprayer head includes at least three enclosure components, including a left housing  1503 , a right housing  1524 , and a light fairing  1513 . The left and right housing  1503 , 1524  keep all of the parts of the electrical system  1200 , pump system  1300 , and fluid system  1400  in place.
