Abstract:
Lighting of buildings is costly in terms of electric power, and in view of this, disclosure is made of apparatus and method for comparison of electric power usage with incandescent or HID, high intensity discharge, lighting source compared to an alternate lighting source, such as fluorescent tube lights, to give the same or adequate light reading on a light meter as attained by an incandescent or HID, high intensity discharge light source then measuring the ampere reading at the same voltage of each lighting source to determine the KW demand to further determine lowest lighting cost, which then in effect will equate to a virtual power plant, which can be a considerable saving of cost and reduction of atmospheric pollution.

     DETAILED DESCRIPTION OF THE INVENTION 
     In all of the following discussion the term “incandescent” is to include as an alternate HID “high intensity discharge”, or other light source, for comparison of electric power efficiency, and this invention is to describe and claim both apparatus and method for comparison of lighting sources, to provide for the most efficient based on electric power demand for equal or adequate lighting at the work plane, and to thus save electric power to provide a virtual power plant through savings in electric power for lighting of the work place. 
     Referring now to FIG. 1 showing elevation view of single point incandescent light source  25 , with electric power line  35 , to an incandescent or HID light bulb  41 . FIG. 2 is a plan view of the single point incandescent or HID light source of FIG.  1 . 
     FIG. 3 is an elevation view of area fluorescent light source  26  with electric power line  34  to this light source  26 . FIG. 4 is a plan view of this fluorescent light source  26 , and fluorescent light tubes  42 . 
     FIG. 5 is an assembly, of the apparatus and computer, for and method of comparing electric power demand of different lighting sources, and FIGS. 6 and 7 are enlarged segments of the apparatus, with FIG. 6, identified as “A” —circuit A lighting standard and FIG. 7, identified as “B” —circuit B light for comparison to standard light in circuit A. The light source in circuit A is an incandescent or HID light  41 , in lighting fixture  25 , at a distance “d” from light meter  23 , and on closing switch  29 , in electric power line  35  the light intensity is indicated in light meter  23 , and the amperage as indicated in circuit A by clamp-on ammeter  27 , and the amperage is shown in window  31 , in panel mount board  17  of the computer  43 . 
     Referring now to circuit B shown in FIGS. 5 and 7, the light source in circuit B may be fluorescent tubes  42  in light fixture  26 , and this light source is at a distance “d” from light meter  24 , and on closing switch  30 , in circuit B power line  34  the light meter  24  shows the light intensity, and this light intensity in circuit B is adjusted to be the same as attained in circuit A, and on equal light intensity to circuit A, clamp-on ammeter  28  shows the amperage of circuit B in window  21 , on panel mount board  17  of the computer  43 . 
     Again referring to FIG. 5 the clamp-on ammeters are plugged into opening  14 , in panel mount  17 , on computer  43 , and select switch  16  for scanning; hours  1 , volts  2 , circuit B or sample  3 ; total system  4 ; rate  5 ; annual hours  39 ; % ratio  6 ; kilowatts saved  7 ; amperes saved  8 ; and each of the scanner stops have an LED light, and data will show in window  13 . 
     The volts may be set by reset switch  18 , switch  19  goes to higher voltage, and switch  20  to lower voltage. On reading the amperage of circuit A the power cost will be shown in window  9 , and the amperage of circuit B power cost will be shown in window  10 . Toggle switch  11  can be switched “up”  12 , to show total KW of circuit B, in window  10 . Total KW of circuit A shows on moving toggle  11  “down” to  40 , to show KW display in window  9 . Electric power entrance  15  to computer is via electric power line  33  and male plug-in  32 . Female opening  22  for communication plug-in. Clamp-on ammeter  27 , of circuit A plugs into computer  43  via line  37 , to probe opening  14  and clamp-on ammeter  28  of circuit B, plugs into computer  43  via line  36  to probe opening  14 . 
     Electric power line  38  connects to both circuit A and circuit B, and line  37  from clamp-on ammeter  27 , in circuit A connects to the computer through female opening  14 . Clamp-on ammeter  28  in circuit B connects to the computer via line  36  through female opening  14 , which is an opening for probes of the clamp-on ammeters  27  and  28 . 
     Circuit “B” can be considered a “sample” in which any other light source can be evaluated by comparison to the standard “incandescent” or “HID” light source of circuit A. 
     Referring now to the clamp-on ammeters  27  and  28 , the clamp-on portion can be opened to allow surrounding of the power lines  35  and  34  respectively, then closing the clamp around the respective power line to get the ampere reading which will show in windows  31  and  21  respectively. 
     Method of metering separate electric lighting circuits for comparative electric power usage, to provide a virtual power plant in electric power savings, an electric power line  35  to a light source  25  in a circuit A and a switch  29  in the electric power line  35  to the light source in circuit A, and closing the switch  29  on the electric power line  35 , and an electric power line  34  to a light source  26  in circuit B and a switch  30  in the electric power line  34  to the light source in said circuit B, and closing the switch  30  in the electric power line  34 .

     A clamp-on ammeter  27  and clamp of the ammeter surrounding the electric power line  35  to the light source  25  of the circuit A, the clamp-on ammeter  27  connected into a computer  43  through a female opening  14  in the panel of the computer  43 . A clamp-on ammeter  28  and clamp of the ammeter  28  surrounding the electric power line  34  to the light source  26  of the circuit B, and the clamp-on ammeter, of circuit B, connected into the computer through a female opening  14  in the panel  17  of the computer  43 . 
     A circuit A amperage reading window  31  in the panel  17  of the computer, and a circuit B amperage reading window  21  in the panel  17  of the computer  43 . 
     A select switch  16  in the panel  17  of the computer  43 , and the select switch  16  scans the selections of hours  1 , volts  2 , sample system circuit B amperes  3 , total system amperes  4 , KWH rate  5 , annual hours  39 , % ratio  6 , KW saved  7 , amperes saved  8 , and each selection made is indicated by a light emitting diode (LED) at its site, and the data may be shown, by LED light in one of the windows  9 , 10 , 13 , 21  or  31 .

     A voltage reset switch  18  to switch to higher voltage switch  19  and a switch  20  to lower voltage, in the panel  17  of the computer  43 . 
     A window  9  to display power cost of the circuit A. A window  10  to display power cost of the circuit B. 
     A toggle switch  11  in “up” position  12  to show power cost of the circuit B in total light fixtures and the toggle switch  11  in “down” position  40  to show power cost of the circuit A in total fixtures, and an electric power supply plug  32  and power line  33  in the panel  17  of the computer  43 , and a female opening  22  for communication plug-in on the panel  17  of the computer. 
     It is further to be pointed out that “LED” stands for light emitting diode, in the above description, and that “HID” identifies and stands for “high intensity discharge” light source.
