THE IRON AGE, September 28, = ott THE LIGHTING spite all that has been accom- plished industrial lighting dur- ing the last two decades, the conditions recently indicated the industrial lighting surveys carried jointly the Committee Industrial and School Lighting and the Commit- tee Lighting Service the nating Engineering Society are far from flattering the industries them- selves the lighting business. While there are some encouraging exceptions this average condition, quite evident that the average lighting conditions industry are much below those which should use good seeing conditions are prevail. While much knowledge ex- ists ways and means lighting various industrial processes, there lack proper standards for the sat- isfactory solution specific lighting problems. has long been recognized, for ex- ample, that the operation power presses has presented problems il- lumination that have been quite diffi- cult solution due the nature the design the press equipment, the changes these designs and the mul- tiplicity operations. investiga- tion has therefore been made the Illuminating Engineering Society determine the seeing volved the operation such equip- ment, and determine satisfactory standpoint quantity and quality light, distribution, contrast and bright- ness and safety. result this study the Committee Industrial and School Lighting has made the follow- ing recommendations Small Punch Presses The light for operations small presses should come from two sources: first, the general overhead lighting, 66—THE IRON AGE, September 28, 1939 which should illuminate the areas front the presses and also serve for the stock and material handling; sec- ond, supplementary lighting, which should used increase the levels illumination the dies.

For supplementary lighting, preferable mount the unit the back the press whenever possible. each case the supplementary light- ing unit attached directly the press frame suitable hanger that the light falls directly upon the die surface, indicated the accom- panying sketch. For mounting behind the press angle-type reflector, either circular, rectangular elliptical shape, hav- ing relatively wide, smooth tion, desired. The unit should have maximum beam candlepower the order 300 350 which should maintained over angle deg.

The mounting posi- tion should such that the filament image not reflected the eyes. the back the press will provide foot-candles some dies. This somewhat higher than mended values Table but with the high depreciation light output en- countered this type work, the il- lumination will soon reduced the recommended values. further recommended that the inside the press frames painted flat white, which helps improve the seeing condition increasing the contrast between the stampings and the background. Lighting Large Presses The lighting for the operation large power presses, with the small, should come from two sources: first, general overhead lighting, which should illuminate the areas around the presses and also serve for stock han- dling; supplementary lighting, which used build the levels the dies. The layout the general overhead system should considered the con- ditions found the pressroom. most plants large presses are located areas where the lighting units are mounted ft. above the floor permit the passage cranes. Also due the fact that the large presses are operated from both front and rear. general illumination required over the entire floor area. recom- mended that under these conditions, symmetrical layout high-bay reflec- tors installed produce level sul } > th e NCLINABLE press lighted from rear with reflector placed light die surface with light source above angle vision prevent glare. the floor not less than foot-candles. further recommended that lighting reflectors the deep-bowl type installed the underside the crane offset the blocking the overhead lighting equipment the crane. Where cranes are not used and lower mounting heights are possible, the symmetrical arrangement according bays should used, spacings and wat- tages conform with modern design practice.
