Engineering Service Detailed recommendations for the use of Ivanhoe reflectors are given in the Engineering Section V, at the back of this book. For special problems, the services of our Commercial Engineering Department are at the command of buyers. 3 Ivanhoe Industrial Line Schedule R HE reflectors listed in the following pages are designed to give those definite distributions of light which have been determined by previous ex- periment to be most satisfactory for the varied re- quirements of industrial plant, store front, bill-board, and similar lighting installations to which metal reflectors are best adapted. Light distribution may seem at first to be a highly technical subject, but it is very easily understood when the action of the reflector on light is thought of as a similar process to the action of a hose nozzle on the water that passes through it. Just as the nozzle is adjusted to throw the water in a fine spray over a broad area with a small quantity per square foot, or to concentrate the water into a powerful stream, so is the Reflector by proper design made to distribute the light broadly over an extended area, to concentrate it into a brilliant beam, or to give whatever intermediate distributions are desirable. Following is an index showing the types of light distribution for which IVANHOE Reflectors are designed and the pages on which the Reflectors are Mageeh INDEX Extensive Distribution “Cleanezy’”” Aluminum Reflectors, page 12. Porcelain Enameled Reflectors, page 11. In the Extensive Distribution the light rays are brought to a maximum at approximately 45°. For uniform illumination space these reflectors at a distance apart equal to two times the mounting height above the plane to be lighted. Figure 1 Intensive Distribution “Cleanezy’’ Aluminum Reflectors, page 13. Intensive Reflectors are especially designed for lighting large factory areas. For uniform illumination, they should be spaced at a distance apart equal to 1% times the mounting height above the plane to be lighted. They are also used for lighting groups of machines such as looms, warpers, lathes, shapers and knitting machines. Figure 2 Focusing Distribution “‘Cleanezy’’ Aluminum Reflectors, page 13. Focusing type reflectors are used for lighting work which requires local illumination of high intensity over a small area. The smaller units may be used over vises, watchmakers’ benches, and similar locations. The larger units, mounted pendant on the ceiling, furnish an excellent unit for the lighting of inspection tables and of high and narrow show windows. The large units also may be used to provide uniform general illumination when they should be spaced 34 as far apart as the height above the plane to be lighted. Distributing Distribution Porcelain Enameled Reflectors, page 14. White Paint Enameled Reflectors, page 15. The Distributing Distribution corresponds to the fine spray from an adjustable nozzle. The light covers a broad area with a low in- tensity. Distributing Reflectors are usually used in warehouses and similar spaces where they are spaced at from two to three times the mounting height. Figure 3 Angle Distribution “Cleanezy’’ Aluminum Reflectors, page 17. Porcelain Enameled Reflec- tors, page 18. Angle typereflectors are used in small single units for the lighting of such machine tools as speed drills, milling machines, shapers and other ma- chines requiring a bright illumination over a small area from a light unit which cannot be placed directly above Figure 4 the work. The larger units may be used for the general illumination of large bays in steel mill buildings where the illumination is provided from large lamps hung from the side columns and for bill-board lighting. Cleanezy Aluminum Reflectors give the distribution of light shown { in Figure 5. Porcelain Enameled Reflectors give the distribution shown in Figure 6. Figure 6 Figure 5 or Sec. I. IVANHOE INDUSTRIAL LINE Catalog Numbering System The LETTERS and NUMBERS of catalog num- bers have the following meaning: The letters designate in order: 1. Type of holder (B or D). Note—Reflectors furnished with the Clip Spring Holder have only two letters in their stock numbers. The first letter gives the finish of the reflector and the second gives the light distribution obtained. 2. Kind of finish (A, for Cleanezy aluminum; E, for porcelain enamel; P, for paint enamel). 3. Distribution of Light (E, extensive; I, intensive; F, focusing; D, distributing; L, angle and MM, Mazda Mill distribution). The number gives the size of the MAZDA lamp with which the reflector should be used to obtain the best results. EXAMPLE—No. BED 60 (See page 14) = 2% inch heel. = Porcelain enamel finish. Distributing light distribution. = Size of Mazpa lamp to be used. EXAMPLE—No. AE-60 (See page 12) Som | Clip Spring Holder. A = “Cleanezy”’ aluminum finish. E = Extensive light distribution. 60 = Size of Mazpa lamp to be used. Sec. I. IVANHOE INDUSTRIAL LINE Holders For Reflectors B, D, and clip spring holders are furnished as a part of the reflector. They are not to be ordered separately. While nearly every holder can be fitted to any reflector, orders should be confined as far as possible to the standard com- binations shown in bold faced type, and must be limited to the combinations listed in this book. The only holder supplied on the 400, 500 and 1000 watt sizes is the B Type, 3% inch heel. B denotes 214 inch and 3% inch heel. The 21% inch heel is supplied on all reflectors below the 300 watt size. The 3% inch heel is supplied on reflect- ors for 300 watt lamps and larger. With the 24 inch heel use the Form O holder, never Form H or holders Nos. 822, 823, 824, 826. With the 3% inch heel use holders Nos. 622, 635 or 672. 2% in.and 3% in. Heel (B Type) The Clip Spring Holder has no letter designation. It provides a quick and dependable method of attaching a metal reflector to a socket. When attaching the clip spring holder to the socket, place the socket shell over the reflector at a small angle. A slight pressure is sufficient to expand the Clip Spring to let the bead of the socket shell slip into the beaded ring of the holder. The tension of the Clip Spring holds the reflector firm- ly in place. This holder is the product of an automatic machine operation, and it is always uniform in size and tension. It is easy to use, substantial in construction, and positive in operation. Clip Spring Holder (Standard) D denotes clamp strap added to clip spring. Used on heavy reflectors and reflectors subjected to strong vibration, Clamp Strap (D Type) Sec. I. IVANHOE INDUSTRIAL LINE Schedule R Finishes on Reflectors The Reflectors listed under Schedule R are supplied in three standard finishes. The finish designated by the letter ‘‘A’’ (see catalog numbering system, page 6) is the ‘‘Cleanezy’’ Aluminum finish. The finish designated by the letter ‘‘E"’ is porcelain enamel. The finish designated by the letter ‘‘P”’ is paint enamel. The standard color of the outside finish of all Reflectors is green. “Cleanezy” Aluminum Finish A—Transparent, washable, pro- tective coating. B—High efficiency reflecting coat of matte aluminum. C—High temperature, white re- flecting base. D—Special open-hearth deep drawing steel. E—High temperature, non-ab- sorbent coating. F—Smooth green exterior finish coat. The ‘“‘Cleanezy”’ Aluminum finish is applied in five coats as shown in the illustration. The metal shell is first treated in acid and scrubbed in hot water until it is perfectly clean. It is then quickly dried to prevent any rust formation. The dry steel is cleaned to remove all dust particles. Coat “‘E”’ is first applied and baked in indirect heating ovens. Coat “C" is next applied and baked. Then in order, Coat F, Coat B and Coat A are applied, each coating being baked separately: At the lower edge of the reflector v~ the coatings are lapped over. This gives five protective thick- nesses at the point where in ordinary reflectors rust formation begins. Reflectors with the ordinary aluminum finish show a marked depreciation in efficiency after a short service. This is caused by dirt particles, which it is almost impossible to remove, lodging in the pores of the aluminum coating. In the ‘‘Cleanezy’’ finish the transparent coating ‘‘A’’ forms a smooth protective surface over the aluminum. This surface does not collect dirt readily. And it can be cleaned easily by washing with a pure soap lather, or with a solution of four parts warm water and one part ammonia. Never use scouring materials, lye, or soaps and cleaners having a gritty substance. Porcelain Enamel Finish Our porcelain enamel finish is applied in three coats. The first is a binding coat. The next two are of the best quality of pure white porcelain for the interior, and of a dark green porcelain for the exterior. Porcelain surfaces will not deteriorate under ordinary service. They are easily cleaned, but porcelain is a form of glass and is therefore liable to chipping if subjected to sharp blows. Paint Enamel Finish The painted finish is applied smoothly to the steel surface and is baked on at a high temperature. The finish is tough, durable, and permanent in color. 8 Sec. I.

ENGINEERING SECTION Recommendations for the Use of Ivanhoe Industrial Line Reflectors (Section I). Ans could be written on the use of Ivanhoe reflectors in factory lighting. Only generalities will be touched on here. For detailed recommenda- tions for any particular class of factory, write our Commercial Engineering Department. Factory spaces may be illuminated by General lighting Local lighting Group lighting depending on the character of the space. General Lighting With general lighting, the room is lighted as a whole, without reference to the work done at any particular point in the room. The light at every point, with this system, should be good for the character of work performed in the room. This type of light- ing is used for foundries, boiler-shops, paint-shops, assembly- rooms, shipping-rooms, warehouses, etc. The distributed unit- system, in which the lights are arranged in squares or rectangles nearly square, is employed. Where coarse work is performed the squares may be large; where fine work is performed they should be small. A size of square and mounting height such as to use the Intensive reflector at its correct spacing, is usually the best, but for fine work or very high ceilings, Focusing reflectors, correctly spaced should be used. For coarse work, the Extensive reflector and spacing is suitable, and for such places as ware- houses even wider spacings are desirable with Distributing reflec- tors. The large sizes of Mazpa C lamps with Ivanhoe metal reflectors are especially good for general lighting in factories. Local Lighting Local lighting is the lighting of any individual machine or oper- ation, usually with a single lamp and reflector. Local lighting ‘s used for bench work, and for lathes, punch-presses, drawing- presses, etc.—any kind of work where light may be needed from a nearly horizontal direction or where a high intensity of illumina- tion is required over a small area. Usually angle or focusing reflectors with small lamps are employed for this work. No. 634, page 23, is a small reflector used with 10 or 15-watt MaAzpa or 30-watt Gem lamps. It is primarily for sewing machine lighting, but may be used for any similar class of work where local lighting is required. AL-40, AL-60, AF-40, and AF-60 are good reflectors for local lighting with their corresponding sizes of lamps. Fig. 1 shows a good example of local lighting. Local lighting is usually used as supplementary to general lighting of a low intensity. 28 Sec. V. ENGINEERING SECTION Bigne. Group Lighting Group lighting, or as it is often called, localized general light- ing, consists in lighting a particular group of machines or a particular area worked on, by general lighting, but with light- units placed with reference to the work so as to obtain light on the work from the best directions. This type of lighting is particularly suitable for large rooms with many machines of the same type, covering for example such operations as weaving, cotton spinning, buffing, metal spinning, small printing-press work, etc. Fig. 2 ENGINEERING SECTION shows a cotton spinning room lighted by group lighting.

ENGINEERING SECTION Wlumination Chart On account of the small effect of ceiling and wall reflection in lighting systems using metal reflectors, it is possible to present a chart (Fig. 3) which will show at a glance the size lamp at a given spacing or the spacing for a given size lamp to obtain any desired intensity of illumination. This chart assumes rooms of average size with average surroundings. In small installations (6 lights or less) especially if the walls are dark, it is well to allow 5 to 15% more light than that shown by the chart. In very large installations, especially if the walls are light, the efficiency will be somewhat better than the chart indicates. Use of the Chart For general illumination which is to be supplemented by local lights at the various machines or work benches, allow 1% foot- candles. For general illumination not supplemented by local lights, allow 3% foot-candles for ordinary work (assembling, painting, packing, etc.) running up to 6 foot-candles for fine work and even 8 or 10 foot-candles for fine work on dark goods. For warehouses, stock-rooms, etc., allow about 1 foot-candle. The room to be lighted by general illumination should be divided into squares or rectangles as nearly square as possible, placing a light at the center of each square. Knowing the area of the square or rectangle and the foot-candle intensity of illumina- tion desired, reference to the chart will show what size lamp to use. Select the lamp whose curve is next above the point of meet- ing of the horizontal line representing area and the vertical line representing foot-candles. If the point does not fall near a lamp curve, the size of square or rectangle may be increased or de- creased. If it is desired to use a certain size of lamp, the problem may be worked the other way; starting with the size lamp and foot-candle intensity desired, the area which the lamp will illuminate can be determined from the chart. The selection of the best size of square or rectangle is important. See the remarks above under general illumination and those below under selection and spacing of reflectors. Selection and Spacing of Reflectors The type of reflector to use, the mounting height and spacing should be determined from the spacing diagram—Fig. 4. In general reflectors should be mounted high to place them out of 31 Sec. V. ENGINEERING SECTION the range of ordinary vision. This means that when there is a choice between two reflectors, the more concentrating is ordinari- ly the more desirable. For example, if the choice lie: between extensive reflectors at an 8 foot mounting height and intensive reflectors at an 11 foot mounting height, the intensive type is the better one to select.

ENGINEERING SECTION Intensive and focusing reflectors are best where fine or exacting work is performed; extensive reflectors for rougher work. The intensive spacing is the best for the great majority of cases. In general, therefore, it is best to select a size of square or rectangle such that intensive reflectors can be used at their correct spacing and obtain a reasonable mounting height. For fine or exacting work, the squares should be such that intensive or focusing re- flectors can be used. Distributing reflectors are not designed for installations in which uniform illumination is desired. They are usually used for warehouses, stock-rooms, etc., where the spacing would be 2 to 4 times the mounting height. For uniform illumination, the reflector giving the widest distribution is the extensive which is spaced 2 times the mounting height. Distributing reflectors give some light at higher angles than extensive but not enough to produce uniform illumination. Some engineers recommend dis- tributing reflectors in work-rooms spaced at about 1.6 times the mounting height above the plane to be lighted. In many cases there is a slight efficiency advantage to be gained by this, but, in general, we consider it better practice to use deep bowl reflec- tors for work-rooms as they shield the lamp filament better than the shallower distributing type. This shielding is especially important with Mazpa C lamps. 33 NUMERICAL INDEX Catalog No. of Standard Reflectors and Fittings Page OYA Nese 6 nO Me ME CR RO Ace 0, 00 10 QOL 2 Toe sebeibiace 5 atecerdie ayers 3g erenarele 10 QOS Sikiever rei teecrtrr css tcesos shancretaents 10 O65 Dida i cicteceeete eis elena Oe evevasa eisgonerete 10 Q660 oe a ceenteemenerette x < Gye Sate tenenats 10 O662S, co ree tersre tines ter soe weet 10 06603. e rin nee hatemtore textes ein aaeueee 10 OGL 2 ete mc rsncre eae isiens asi saciens. eters 10 ODT Sia er aycieiae meen teat eee et note 10 AGO). rarotes sree Riana eRe Reel acre! as 5/Pa tence 2%} OL Sxeccte hele terete ev Nokes isi'ehsine'= 23 CP ey ae mtiatiere. 1 ooo 6 DCO Ge ROO 9 GVH Perr ainm on o.% Seetro.o em crOrrC Aton 20 G29 5 coat No Arteore oer eaeLemcn vis risa coger 20 (KR Hn leita ticwo fc cis CORR 23 634.5 te chloe Cota eens Seema 23 635), Foclaneicadertaasce ae Soe oie 9 CY Ma peep cena en nici yon 5 dora 9 1A Pree 8 Cap OREO oc tI a CeCe 26 TD Bicnetevacaccvereho, ole ole re) ele leeek teehee t's .=¥s 26 (PA ER ene PO re cu 2A O oa 26 TA Motels or Hex toteee eter al conalcaiets Chepeanietey © 26 TAQ) occ tot keris, Seen nibh s Sea 27 VEL) De sence crite Toro orad O 6 choke ai T51 rok eleh caskite tet sto eerermecteters 2s TS BS icbate othalclatate Peta ote ate Shoe 26 Pit: Ran cre ere eho noe to eo 27 VS ees eae cick HORS ee eh eer ao 27 (EV Qari tek gt Or Gene ORS sant, 27 (RY Ep oet AIRE CRO aa ae toickris Ser 5.0 27 7 [SG Cea PRE ROI RID LTC EITC 27 (HES eRete mon ior enon 25, 26, 27 YU er th to OEE OO THOS 25, 26, 27 TSO oaeer ui cae aute 257) 26527 hy A PO otitis, MUO RS Pots eae SS ce 26 NEA oye Pata he he eS OF OOO eon ots 27 TL DO eerniraiard ete ser ett ensl at ia te vcstacel =i 26 (AO) Ue eae eh, Sean Corner On cau tyns toe: 26 1 SAR pee craic. to akere mae tone 23 BOQ ie cet m wat erctanenstsNers 0 cepars te Wyvieyevmts 25 BOS. ots Monee he ee aha 25 SOA Sictes ee rtoe outa xeon ou stista atari te 25 BOS eter atietire oe iva reas cue Sore 25 $062 2 xatetcmie scat cereinereraeste 25 SOT sedin leah ocr eis Oa ote 25 SOS: acer eee» Sie ee ee oe 25 B09. hans Wraith area awe Saksherateesises 25 Catalog No. of Standard Reflectors and Fittings Page BQ isc alive «Gays ture moka anape ee yt 9 B23 a Ssieisst sale iaveus, Sleueun aiahere eee 9 BQA.
