From soccerstadiums to fit-ness centres –sports andleisure amenities are a big investment, costly

to build and costly to run

investment hinges on how

just architectural allure to

ensure acceptance,

comfortable, especially

recreational users, most of

whom only have time for

sport in the evenings, i.e

when it is usually dark That

is where lighting comes in

Sports halls

Most sports halls are

suit-able for many different

sports Some are also used

for non-sporting events,

e.g events staged by local

clubs and associations

And sports hall lighting has

to cater to all the visual

re-quirements of these diverse

forms of use So before

any move is made to

de-sign a lighting system for

a sports hall, it has to be

established which sports

are going to take place in

it and what other forms of

use are anticipated (see

“Supplementary lighting for

multi-purpose halls”, Page

5) One thing that must

al-ways be ensured is a level

of lighting high enough to

meet the requirements of

the sport presenting the

most demanding visual

task

Good general lighting

alone cannot meet all

re-quirements

Special-pur-pose sports halls which are

custom-built for specific

sports, such as tennis,

squash, riding or shooting,

need supplementary

light-ing This is essential for

performance of the visual

tasks presented by the

sport in question

lighting requirements setout in the European stan-dard DIN EN 12193 and onthe specific geometry of thehall A regular luminairearrangement is customary

Whether luminaires are cessed, surface-mounted orsuspended depends on theheight of the hall and thenature of the ceiling Lumi-naires for 26 mm or 16 mmdiameter three-band fluo-rescent lamps and round orrectangular spots for metalhalide lamps are a suitablechoice Luminaires used insports halls need to beimpact-resistant

be mounted as high aspossible so that playersare not dazzled when theylook up at a high-flyingball The arrangement andlighting characteristics ofthe luminaires determinethe glare situation for play-ers and spectators, whosevisual requirements mustalways be considered inany appraisal of the light-

Lighting requirements

On the following pages are

tables showing the key

minimum lighting

require-ments of individual sports

The data are taken from

DIN EN 12193 This

stan-dard sets out requirements

for other lighting quality

features, too, such as

maintained at all times.Design values should be

at least 25 % higher thanservice values

Lighting uniformityFor good vision, it is im-portant to ensure not onlythe requisite level of light-ing but also an even distri-bution of lighting: pro-nounced patches of lightand shade overtax the hu-man eye because of theneed for constant adapta-tion Uniformity of illumi-nance (horizontal and ver-tical) is expressed as the

illuminance

Lighting classes

Lighting requirements for a

youth team soccer match

are not as high as those

for a national team game

To meet these diverse

re-quirements for players and

spectators, DIN EN 12193

sets out three lighting

classes with different

light-ing criteria The values

stated are minimum

re-quirements The higher the

competition level and the

farther spectators are away

from the action, the higher

the lighting class required

(see table)

Lighting class I:

Top-level competition

events, top-level training

Lighting class II:

Medium-level competition

events, power training

Lighting class III:

Simple competition events

(usually no spectators),

general training, general

school and leisure sport

Supplementary lighting

for multi-purpose halls

For economic reasons, it

may make sense to design

a new building – or

re-equip an existing one – as

a multi-purpose hall from

the outset, rather than have

just a sports hall It will

then have various possible

uses: as a lecture hall or

general lighting should be

dimmable and backed by

supplementary lighting

systems on separate

cir-cuits with a lighting control

system customised to

meet requirements

Important: All

multi-pur-pose halls are also sports

halls, so all luminaires

must be impact-resistant

Luminaires which do not

meet this requirement, e.g

spots for stage-lighting

in-stalled less than 5 metres

above floor level, need to

be removed for sporting

activities

In boxing, the speed and

force of movements in the

ring necessitate horizontal

illuminance values from

500 to 2,000 lx In addition,

to ensure visual comfort

for boxers, referee and

spectators, DIN EN 12193

requires lamps with good

colour rendering is also a

prerequisite for video and

Lighting for squash courts

needs to meet very high

requirements, especially in

terms of uniformity of

light-ing The rubber ball is

much smaller than a tennis

ball, frequently shoots

up-wards at angles close to

the vertical and travels at

speeds up to 200

kilome-tres an hour for most of

the game Because the

vertical surfaces of the

court permit complex ball

trajectories, players have to

change positions and lines

of vision very fast, whilst

always keeping track of

their opponent’s

move-ments

An effective solution here

is a single row of

lumi-naires parallel to the front

wall and two rows of

lumi-naires parallel to the side

walls The front wall

lumi-naires should have an

asymmetrical beam angled

towards the wall and need

to be well shielded on the

players’ side to avoid

di-rect glare Reflected glare

is prevented by positioning

the luminaires at least a

metre from all walls

A horse’s twilight vision isvery highly developed and

it is more sensitive to ferences in light than ahuman being So to avoidconfusing and upsettingthe animals, marked lumi-nance fluctuations need to

dif-be avoided Owing to dustand heightened humidity,all luminaires used in in-door riding arenas should

be designed to a higherdegree of protection

When track riders getgoing, they can’t stop fast– especially since theirbikes don’t have brakes

Even so, they stay as close

as possible to the riderahead to get maximumbenefit from his slipstream

To avoid collisions andpainful falls, riders need to

be able to gauge preciselywhat their opponents arelikely to do, even at highspeed And that calls forgood visual conditions

The illuminance values quired by DIN EN 12193apply to the surface of thetrack The 1000 lx verticalilluminance required addi-tionally at the finish facili-tates the visual task of thejudges and plays a signifi-cant role in determiningthe quality of photo-finishpictures

Indoor ice rinks enable skaters to train whateverthe weather And as mostrinks are used for all thedifferent skating sports –ice hockey, speed skatingand figure skating – thelighting needs to be de-signed for the most de-manding: ice hockey andspeed skating Any lightingmeeting the requirements

ice-of these two sports is alsoright for recreational iceskating, for which most in-door rinks are used on aregular basis

Ceiling luminaires should

be arranged in a uniformpattern over the surface ofthe rink To raise the illumi-nance in goal areas forice hockey, luminaires caneither be more closelyspaced in these areas orfitted with more powerfullamps

Because of the speed andsize of the puck used in icehockey, it is not always easyfor spectators to follow itsmovements The percepti-bility of a flying puck can

be significantly improved byraising the luminance of thebackground and creatingbetter contrast conditions

The rink surroundings –including the spectatorstands – should therefore

be bright

As in other sports halls, theluminaires used in ice rinksneed to be impact-resistant

Basically, lighting hereneeds to make safe use

of all apparatus possible

In workout areas, this callsfor at least 300 lx horizontalilluminance The arrange-ment of luminaires should

be defined by the tus Care must be taken,for example, to ensure thatinformation on displays andmonitors is not obscured

appara-by excessive reflected glare

Also, as direct eye contactwith luminaires can dazzle,asymmetrical beam lumi-naires mounted outside thedirect glare zone on theceiling are a sensible solu-tion where exercises areperformed face-up

Special lighting comfort isachieved where ceiling lu-minaires can be dimmedfor zonal lighting control.The lighting can thus bebetter tuned to the needs

of those training Being ferentiated, it also creates

dif-a more dif-attrdif-active scene.Supplementary accentlighting with wall lumi-naires, for instance, makesfor a more interesting andinformal atmosphere The lighting concept forworkout areas can also

be adopted for spinning,power step, stretchingand back-muscle trainingrooms In at least one ofthe rooms, the light colour

In the water, athletes of

different disciplines have

different lighting

require-ments For water polo

players, for example,

ambi-ent brightness is more

im-portant than for

competi-tive swimmers, whose

attention is focused on their

lanes Swimming

instruc-tors, coaches and pool

attendants need a good

view of the water from the

pool edge At competitions,

spectators need to be able

to see what is happening

in the pool from a distance

Experience shows that

good visual conditions for

outsiders generally mean

good visibility for athletes,

whatever the discipline

Lighting requirements can

differ widely, however, from

one indoor pool to another

Because water reflects

direct incident light so

in-tensely, ceiling luminaires

should be mounted at the

perimeter of pools Where

this is not possible,

reflec-tions can be reduced by

mounting asymmetrical

beam luminaires over the

water For small pools,

luminaires installed above

High degree of protection and protection against

corrosion

Because of humid, chlorinated, even salty air, luminaires

for indoor swimming pools need to meet high standards

of electrical reliability and protection against corrosion

Operational reliability calls for luminaires designed to

high degrees of protection, at least IP 44 for lamp and

ballast compartment The high degree of protection and

corrosion-proofing of quality luminaires designed for

such applications ensures long years of service

Impor-tant note: luminaire fastening elements must also be

cor-rosion-resistant; the most reliable are fastenings made of

austenitic stainless steel

to perform their visual taskproperly

As in all damp interiors,luminaires installed inshowers and lavatoriesneed to be designed to anappropriate degree of pro-tection Where spraywater

is a hazard, this is IP X4

Where shower heads inthe wet zone of showerrooms are not mounted infixed positions, the higher
