PARK LIGHTING 



803 



roque and horseshoe-pitching courts are examples 

 of definitely bounded playing areas. 



In the lighting of large fields, or areas on which 

 activities are not confined within definite bounds, 

 the problem becomes more difficult and oftentimes is 

 peculiar to each individual project. The lighting of 

 fields for football and track meets, and the lighting 

 of playgrounds and bathing beaches fall in this cate- 

 gory. 



The problem of lighting for outdoor sports clearly 

 resolves itself into one of so choosing and locating 

 the lighting units that ample illumination is obtained 

 at the place or places where it is needed, with the 

 minimum of shadows and spottiness on the playing 

 area. At the same time the supporting standards 

 must be located well out of the way of the players 

 and so arranged that glaring light sources do not 

 defeat the purpose of the installation. 



THE LIGHTING EQUIPMENT 



The choice of suitable equipment for outdoor 

 lighting depends upon the characteristics of the light- 

 ing fixture and how well it meets the requirements of 

 any particular application. There are four types of 

 lighting equipment generally used for outdoor light- 

 ing. These are discussed briefly here: 



RLM standard dome reflectors. The reflector 

 shown in Plate 294 is widely used for industrial 

 lighting, and is recommended for many outdoor 

 applications because of its high efficiency and design 

 which give a favorable distribution of light downward 

 at useful angles. It is made of enameled steel, is 

 durable and rugged. This type of reflector is recom- 

 mended in most cases for overhead lighting of areas, 

 where the reflectors can be mounted on poles or sus- 

 pended from cables at frequent intervals. RLM 

 reflectors give a high degree of illumination on hori- 

 zontal surfaces. White bowl lamps should be used 

 with the RLM reflectors so as to prevent excessive 

 glare from the bright lamp filaments. 



Deep bowl reflectors. Deep bowl reflectors, such
