`ABSTRACT
`[57]
`A method of producing a composite beam of uniform
`light from a plurality of defined beam, high-intensity,
`luminaires mounted on a luminaire assembly, adapted
`for use with a mobile mounting pole. By determining
`the characteristics of the defined beam produced by
`each luminaire, the area to be lighted, and the place-
`ment and numberof luminaires to be used, the individ-
`ual luminaire fixtures can be aligned to form a compos-
`ite photometric beam, meeting the predeterminedlight-
`ing requirements. The luminaire assembly is adjustably
`designed as a composite unit for a mathematically de-
`rived model of light energy configuration required to
`illuminate various shaped andsized target areas, such as
`football fields, etc.

`COMPOSITE PHOTOMETRIC METHOD
`
`BACKGROUND OF THE INVENTION
`1. Field of Invention.
`. This invention relates to the composite aiming of a
`plurality of individual luminaires, more particularly to
`‘the aligning of a plurality of defined beam, high-inten-
`‘sity luminaires to.produce a composite beam of uniform
`light for use with mobile lighting systems.
`2. Description of the Problemsin Art.
`Traditional methods of providing uniform light from
`a plurality of luminaries have relied on structures which
`are erected on-site, at which time individual luminaire
`fixtrues are aimed with respectto different points on the
`targeted area. Target areas as large as baseball diamonds
`or football fields require very substantial time and effort
`for post-erection, on-site aiming to produce the desired
`lighting effect. Literally each lamp of eachlighting unit
`holding a plurality of luminaire fixtures mustbe individ-
`ually aimed upon the selected target site (playing field)
`by utilizing at least one person atthetop of the lighting
`unit support pole and one person at the targetsite.
`Attempts have been made to reduce this on-site ad-
`justment and aiming time by predetermining the light-
`ing requirements of the targeted area, and then design-
`ing the make-up ofthelighting fixtures to best solve the
`lighting requirements, taking into account efficiency,
`economy and limited interference with the events hap-
`‘pening on the targeted area. Examples of this “pre-
`designing” are Neely, U.S. Pat. No. 4,141,056 a tennis
`court floodlighting system (and Neely Reissue No.
`26,588). However, on-site manual aiming of the lumi-
`naire fixtures is still required, though the process is
`simplified by the pre-designing.
`All the above mentioned problems are further ampli-
`fied when applied to mobile lighting systems. With the
`proliferation of color TV, there is a real need for a
`mobile lighting system which is not only easily assem-
`bled, dissembled, and moved from location to location,
`but also produces a uniform, beam to promote repro-
`duction. In one particular application of the invention,
`there is a desire to broadcast sports activities, such as
`football games, at night, so that the game may be more
`freely scheduled for television convenience rather than
`on the basis of whether or not the playing field has
`permanentlights. This, of course, cannot be done with-
`out lighting whichis sufficient for quality transmission
`of the event by television. Significantly the expense of
`installing permanent lights when the numberofnight-
`ime televised events will be very small, comparedto the
`cost of the ighting,
`is not cost-efficient for many
`schools. Additionally,
`the aiming and maintenance
`problemsdiscussed above, coupled with theinitial high
`expense, render. permanentlighting installations often
`impractical.
`Asearlier mentioned, nightime television broadcast-
`ing also presents the problem of scheduling flexibility.
`Many times a network may desire to show a gameat
`nightso it will not conflict with other scheduled events.
`Currently this cannot be done unless the schools in-
`volved have permanentlights. However, since nightime
`television lighting would be needed for only a handfull
`of games(usually only one) for each particular stadium
`in a year, permanentinstallation of lighting for such an
`occasional happeningis not justified.
`Therefore, there is a real need for mobile lighting
`systems which are efficient, economical, easily trans-
`
`2
`portable, and can produce the strict defined lighting
`standards needed for television broadcasts.
`Performance standards for lighting level are mea-
`sured in foot candles(fc), the common measurement of
`light levels. The needed foot candles are determined by
`the sport being played,thesize ofthe field, the shape of
`the stadium, its location, etc. The following are exam-
`ples of standards used for different sports:
`.
`1. Baseball —recreationalskill level; greater than 320
`foot field radius 50 fc infield/30 fc outfield.
`University —100 fc infield/70 fc outfield.
`Major league —200 fc infield/150 fc outfield.
`2. Football -University —100 fc.
`Professional —200 fc.
`Another performance standard for the lighting sys-
`tems is the maintenance of the minimum standard for
`uniformity oflighting throughoutthe playing area. This
`is important not only for television coverage, but also
`for the sport being played. The evennessof the lighting
`is called “uniformity” and expresses a ratio between the
`maximum and minimum foot candles on the area. Uni-
`formity of light is just as important as absolute level of
`light. Objects such as baseballs will appear to change
`speeds as they pass from dark to light areas in a non-
`uniform light, thus making them difficult to follow.
`The minimum standard for unifomity for most sport-
`ing events is three to one. This means that no spot on the
`field should be less than one-third ofthe brightest illum-
`ination of another spot on the field: Uniformity is as
`important on a 30 foot candle recreational softball field
`as it is on a major league ball field lighted to 200 foot
`candles, since the lack ofit will have an adverse effect
`on player performance.
`Uniformity is directly related to aiming of the lights,
`and again, becomes an amplified problem when dealing
`with mobile. lighting.
`Pre-aiming of a plurality of luminaires contained in
`one lighting unit, has been attempted for permanent
`lights. By determining and organizing the lighting prop-
`erties of the individual luminaires and applying this to
`the targeted area, lighting units have been designed
`wherein the individual fixtures are preset to produce a
`cetain beam pattern. Hayakawa, U.S. Pat. No.
`4,025,777, a clinical illumination apparatus, presets a
`plurality of luminaires to produce a pinpoint, high inten-
`sity light for use in medical applications. Cahill, U.S.
`Pat. No. 1,235,527, an illuminating system for baseball
`and other games, predesigns a light pattern for the il-
`lumination of a playing surface, based on a numberof
`lighting units. Van Dusen, J., U.S. Pat. No. 3,660,650,
`utilizes ‘a plurality of luminaires that are adjustable so
`that several pre-selected lighting patterns can be uti-
`lized.
`However, none of these prior art attempts show or
`contemplate the factory aligning of a plurality of lumi-
`naire fixtrues with respect to one another as measured
`against a fixed cross-beam reference to present a com-
`posite, uniform photometric beam which can be usedin
`combination with an adjustable mobile rigging to allow
`numerical adjustmentoflighting quality and quantity to
`' match predetermined computer derived models. Also,
`as a result of this invention, only one aimingofa single
`fixtrue is needed on-site to effectively aim the entire
`lighting unit. While some of the referenced patents do
`show a predetermined beam pattern formed from a
`number of luminaires, these patterns are not afjustable
`for different fields by simple movement of a mobile

`rigging unit and on-site aiming of a single luminaire for
`each unit assembly, resulting in the capability of light-
`ing quality and quantity.
`“Thepriorart has not solved the problem ofefficiently
`and ‘economically designing and implementing lighting
`systems which can be pre-aligned, transported tosite,
`used, then removed from the site to be transported to a
`different site and realigned by adjusting only a single
`luminaire to meet the defined lighting standards re-
`quired for an entirely different field.
`Finally, the prior art has not surrmounted the inevita-
`ble problem of inadvertent or acdidental misalignment
`of a lighting unit.
`If prior art lighting units are misaligned because of
`wind, shock, or other calamity, there is no easy method
`to re-aim the unit without re-aiming all luminaires. This
`is especially critical if the misalignment occurs during
`an athletic event which is in progress.
`Therefore, it is an object of this invention to provide
`a method of aligning a composite photometric beam
`from a plurality of defined single beam high-intensity
`luminaires for use with a mobile lighting system.
`A further object of this invention is to provide a
`method for the aligning of a composite photometric
`beam for different sized athletic field target areas and
`uses.
`A further object of this invention is to provide a
`composite photometric partially prealigned beam
`wherein only one aiming point on the targeted athletic
`field area is needed for one luminaire to align the entire
`composite beam for all the luminaires of cross-beam
`assebly.
`Another object of this invention is to provide a
`method wherein corrections in aiming can be made
`continuously and remotely while in use, and on-site.
`A further object of this invention is to provide a
`method wherein a pre-aligned composite photometric
`beam can beintentionally moved to illuminate another
`object, then immediately re-aimed on the original target
`area, to again give the defined field lighting.
`A still further object of this invention is to provide a
`method wherein the targeted area(i.e., a selected out-
`doorfield) is analyzed to determine how many lumi-
`naires and composite photometric beamsare to beused,
`and to determine the location of mounting poles, or
`other mounting structure, to provide a uniform target
`area lighting.
`These and other objects of the invention will become
`apparent with reference to the accompanying specifica-
`tion, drawings and claims.
`SUMMARYOF THE INVENTION
`
`According to the method ofthis invention, a plurality
`of defined beam, high-intensity luminaires are mounted
`on a cross-arm assembly. The cross-arm assembly is
`adjustably mounted on the end of a mobile mounting
`structure, for convenience referred to herein as a
`“pole”. The plurality of luminaires are pre-aligned, for
`example at the factory, to produce a composite photo-
`metric beam of uniform light. The cross-arm assemblyis
`mounted to the mounting pole in such a mannerthat it
`’ canbe adjustably tilted by remote control.
`Aligning of the luminaires is accomplished by first
`determining the dimension characteristices of the field
`to be lighted. The number of mounting pole locations
`and individual luminaires on each cross-arm assembly
`are then. determined. One then determines the light
`characteristics needed for the target area. For example,

`knowingthat for good light beam efficiency for athletic
`fields an intensity brightness of light areas to dark
`should not vary any greater than three to one(lightest
`to darkest), one can determine the required intensity of
`light needed overthe field area. Since one also knows
`the entire field characteristics of the individual lumi-
`naires, one can determine how each luminaire should be
`aligned with respect to the vertical and horizontal coor-
`dinates of the cross-arm or luminaire assembly unit.
`The resulting aligned plurality of luminaire fixtures,
`will thus produce the desired uniform intensity in the
`target area. Using the adjustable cross-arm assembly’s
`vertical and horizontal armsas fixed reference points,
`allows the whole lighting unit to be aimed on site by
`utilizing just one aiming point on thefield, and adjusting
`a single luminaire to the field aiming point.

`DETAILED DESCRIPTION OF THE
`PREFERRED EMBODIMENT
`
`In accordance with the invention and with reference
`to the drawings, in particular FIG. 1, there is shown a
`mobile lighting array 10 including a lighting rack frame-
`work 12 holding a plurality of aligned luminaires 14
`along the horizontal cross-bars 16 of framework 12.
`Framwork 12is tiltable by means of remotely controlla-
`ble hydraulic cylinder 18 which is connectedto vertical
`support bars 20 at one end and boom jib 22 at the other.
`A video camera 24 is mounted upon framework 12 to
`facilitate remote aiming of the array 10.
`Byutilizing the parallel nature of horizontal crossbars
`16, luminaires 14 can be factory aligned to produce a
`composite high intensity beam from the fifteen individ-
`ual defined beam lamps 14.
`With reference to FIG.2, it can be seen how lighting
`array 10 is mounted upon extensible and collapsible
`boom 26 which is in turn 360° pivotal aboutits attach-
`ment point to V-shaped boom jib 22 is attachedat its
`lower ends to the upper end of boom 26, as shown in
`FIG. 3. The upper end of V-shaped boom jib 22 is at-
`tached to vertical support bars 20 by hinge bolts 36
`which extend transversely through vertical support
`bars 20 and horizontal tubes 38, which are rigidly at-
`tached to the ends of boom jib 22. Hydraulic cylinder 18
`attaches at its lower end to cross member 40 which
`extends between opposite sides of boom jib 22, and
`attaches at its upper end to pivot bar 42. Pivot bar 42is
`attached at opposite endsto ears 44 ofvertical support
`bars 20. The exact structure of mobile lighting array 10,
`boom jib 22 and boom 26 are set out more specifically in

`center of the field, coordinates (— 165, 70) being ap-
`proximately the upperleft corner ofthe field, and (165,
`—70) being approximately the lower right hand corner
`of the field. The positions of the trucks 28 are desig-
`nated by “Pole 31 135, 360” and so on. The numbers
`located on thefield itself represent location of the 96
`aiming points and the computer derivedintensity in foot
`candles for each of those aiming points.
`~
`From the above requirements specifications, the fol-
`lowing information is ascertained. The numberof lumi-
`naires to be used is 180; the number ‘of target points on
`the field are 96; the average intensity in foot candles
`across the field in 111.194; the maximum intensity in
`foot candles is 148.372; the minimum intensity in foot
`candles is 49.548; the ratio of the average intensity to
`minimum inténsity is 2.244; and the uniformity of inten-
`sity ratio is 2.994.
`The computer, knowing the aboveinput information,
`then determines the exact aiming points for the individ-
`ual luminaires 14 to create composite beams for each
`lighting array 10 to meet intensity specifications out-
`lined above. An example of the aiming points for one
`lighting array 10 would be those associated with the
`point marked pole —105, —350. By knowing that this
`lighting array 10 will be held 165 feet in the air, the
`followingX and Y coordinates on the schematic map
`are determined to be the desired aiming points for the
`luminaires 14:
`
`—150, 50; -
`— 130, 40;
`—75, 50
`—70, 40;
`
`—150, —40;
`_ —100, 50;
`—90, —40;
`25, 50;
`
`—125, 50;
`—110, — 140;
`—50, 50;
`—50, 40.
`
`Knowingthe exact aiming points for each luminaire 14,
`along with the height. the lighting array will be. raised
`abovethe field, the exact angular horizontal and verti-
`cal attitude of each fixture can be selected. Thus, the
`thirty luminaires 14 for the lighting array designated as
`pole —105, —350 are to be pre-aimed byutilizing pro-
`tractors 52 and 53'in both the horizontal and vertical
`planes as follows. For each respective aiming point
`listed above, the numberof luminaires set out in the left
`
`30
`
`35
`
`45
`
`50
`
`35
`
`65
`
`Thus, the above table directs the factory pre-aimers to
`tilt three luminaires 14 of the array to be placed in the
`position — 105, —350, 26° to the right and 20.3° verti-
`cally downward with respect to horizontal crossbar 16
`and vertical support bars 20, so that they will corre-
`spond with aiming point (90, 50). By following this
`procedure with all six lighting arrays 10, six composite
`photometric beams will be formed which will fulfill the
`uniform lighting requirements of the football field for a
`color televised nightime football game.
`Thus, it can be seen the invention meetsat least all of
`its stated objectives. It is to be understood that changes
`and modifications can be made in the method while
`staying within the boundaries of the invention.
`I claim:
`1. A method of producing a composite beam of uni-
`form light from a plurality of luminaires, each having
`defined beams, and each mounted on a luminaire assem-
`bly adapted for use with a mobile mounting structure,
`said method comprising:
`determining thefield size and description, the number
`of pole locations, and the fixture configuration for
`each pole;
`ascertaining the required light intensity needed over
`said field to provide the pre-selected, defined illum-
`ination model;
`ascertaining the individual beam characteristics of the
`defined single beam projected by each fixture of
`said total fixture configuration;
`determining the horizintal and vertical coordinates of
`each such fixture relative to the luminaire cross
`arm assembly upon which it is mounted;
`aligning each of said individual fixtures of said total
`fixture configuration in accordance with the pre-
`determined horizontal and vertical coordinates
`such that whenlit, they combine to form a compos-
`ite photometric beam; and
`moving said mobile luminaire assemnly to said field
`and placing it in location, and aligning said mobile
`cross arm assebmly by aiming one ofsaid fixtures to
`a preselected aiming point, and
`thereafter locking said cross-arm assembly to said
`pre-aimed position.
