These recommendations relate to the lighting
of indoor and outdoor tennis courts, that is,
all buildings or areas specifically designed
for the sport of tennis.
Whilst the dimensions and marking of tennis
courts are standardised, the design of lighting
both natural and artificial will depend on the
individual site conditions. For this reason,
indoor and outdoor courts are dealt with separately.
This dimensions of tennis courts are shown in
Figs. 1 and 2. The height of the net is 0.91
to 1.06 m. The diameter of the tennis ball is
6 . 3 cm to 6.6 cm. The ball can be white, offwhite
orcolouredand has a matt finish. Grass,
shales, asphalt or an concrete ar.e the most
common surfaces used for outdoor courts, whilst
indoor courts can use painted wood, plastic,
rubber or synthetic fibre carpets. Inflatable
structures can use all the above surfaces except
grass. It is not possible to draw up a comprehensive
list of court surfaces as this is the subject
of constant experiment within tennis clubs.
The general requirements for lighting of sports
events for colour television are given in CIE
Publication No. 28 "The Lighting of sports events
for colour TV broadcasting", 1975. It should be
noted that unlike most of the sports areas described
in that publication, the teleuision cameras for
tennis are positioned at the ends of the court.
As floodlights behind the cameras would cause
unacceptable glare to players, the television
lighting must be positioned at the sides of
the court. With this system it is still possible
to obtain good quality television pictures.
