The guide to sports lighting -take tennis court for example

The stadium lighting market is growing fast in these years. One of common factors enhancing the growth of the market is replacing traditional light with LED light. In addition ,there are many new stadiums being constructed which also contribute to speed the pace of the growth. When talking about sports no matter what participants or spectators all desire to have a good visual effect when in the stadium or on sports field. This requires suitable lighting fixtures to light up sports facility with bright and comfortable environment. What should you think of and what should you know before started your project? Is it confused you? Follow these steps may you have a clearer idea that how to begin.

Step 1: Two kinds of common tennis court

Outside tennis court (Class III)

Indoor tennis court  (Class III)

Step 2: The reason we need tennis court lights 

To meet people’s desires that playing tennis at anytime they expect and not be effected by day or night, indoor or outside and what is the weather like that day. Without lights you can image that you need to rely on the daylight. Otherwise you are impossible to play tennis at night. Even if in the daytime when the illumination of indoor tennis court is insufficient, It would be have a bad influence on the visual effect and may affect players’ mood. That also is another reason why we need extra light source to replenish lighting.

Step3: The factors we need to considerate 

• Dimension of the court

It is necessary that having a clear mind of the scale of on-hand project. 

• Illumination level

Good visibility enabling both players and spectators to follow the progress of a game.

• Uniformity

Good illumination levels and even distribution of light across the playing field surface.

• Relevant government regulations

As what you see at other essay, of course, may not as well, there are regulations about sports lighting level that lay down by government and any other authorities. It would be a effective way as a gist for us to refer that how to undertake own project.

• Cost

Include lights cost, shipping cost, installation cost, running cost and maintenance cost etc.

• Spill light

The potential impact on the environment of light spill from outdoor lighting installations should be considered during design of installations.

Step 4: Refer to the guideline by government or any other relevant authorities

Reference to the Europe sports lighting standard EN12193:2008

Sports field standard

Sports field standard
Class I	Top-level national and international competitions (non-television broadcast)	Big-sized numbers of spectators. Require long viewing distances for spectators.
Class II	Mid-level competition,regional or local club competitions	Medium-sized numbers of spectators. Sports field is smaller than the Class I field.  Viewing distances is shorter than Class I stadium, medium distance. High-level training may also be included in this class.
ClassIII	Low-level competition, local or small club competitions	Meet the private recreation demand. Few spectators. General training, school sports and recreational activities.

Lighting parameters for outdoor tennis courts  

Lighting parameters for outdoor courts
	Horizontal illuminance	Uniformity of illuminance	Glare	Light colour temperature	Light colour rendering
	Eh average (lux)	Emin/Eh ave	GR	(K)	Ra
Class I	> 500*	> 0.7	< 50	> 4000	> 80
Class II	> 300*	> 0.7	< 50	> 4000	> 65
Class III	> 200*	> 0.6	< 55	> 2000	> 20

Lighting parameters for indoor tennis courts

Lighting parameters for indoor courts
	Horizontal illuminance	Uniformity of Illuminance	Glare	Lamp Colour Temperature	Lamp Colour Rendering
	Eh average (lux)	Emin/Eh ave	GR	(K)	Ra
Class I	> 750*	> 0.7	< 50	> 4000	> 80
Class II	> 500*	> 0.7	< 50	> 4000	> 65
Class III	> 300*	> 0.5	< 55	> 2000	> 20

Step 5: Choose suitable lighting fixtures to get appropriate illuminance on the sports field according to the relevant standard and any other data of project

• meet the required standard of relevant government or any other authorities.
• participants do not suffer from disability glare when playing.
• spectators can own a clear visual viewing and not affected by illumination
• calculate the demand quantity based on the scale of your project, include the size of sports field, the lay out of the pole and the height of the lighting fixtures
• generally the mounting height of a single court is between 8 and 12 m   
• focus on the surrounding environment and choose the appropriate installation method. In general, pole mounting and wall mounting is familiar in the outdoor tennis court project. Hook mounting and bracket mounting is common in the interior project.
• Fully consider the potential lighting pollution

Other products property analysis

The property estimation of various lights on the market
Lamp type	Range of suitable wattanges	Efficacy lm/W	Advantages	Disadvantages
Metal halide	400 to 2000	60 - 100	White light with good colour rendering，High efficiency，Low running costs，Relatively long lifetime	High replacement cost ，Length of time to reach full strength (10-15 minutes)
High-pressure sodium	250 to 1000	90-130	Very high efficiency, low running cost, Long lifetime	Poor colour rendering，Length of time to reach full strength (10-15 minutes)
Fluorescent	55-60	60 - 100	Good colour rendering and low glare, High efficiency, Suitable for use with time clocks	Inefficient at low temperatures，Require deflectors to enable light to diffuse in correct direction, Noisy, therefore distracting to players，Low lumen package
Tungsten halogen	500-2000	20-25	Good colour rendering ，Low initial cost，Suitable for use with time clocks，Relatively small fixtures	Short lifetime，Low efficiency，High maintenance and operating costs

Our AGC lighting fixtures analysis

Our AGC lighting product
Light Type	Application	Range of Suitable Wattages	Efficacy lm/W	Work temp	CRI	Superiority
LED	indoor tennis court	180w-600w	135-155	-30℃~+50℃	Ra70, Ra80	Compare to the Metal halide and High-pressure sodium etc, we could provide higher lighting effeciency at smaller wattage , save more energy. The work temperature of our lights rang from -30℃to 50℃, you don't worry about the fixtures will be insufficient when at the low temperature. Good colour rendering. Lower running cost, long lifetime, turn on immediately
	outdoor tennis court	450w-600w	160	-30℃~+50℃	Ra70, Ra80

Step 6: Apply to your project

for example,Poles mounting on a common tennis court field

Generally our lighting poles are set up the either side of the Total Playing Area .That is the white colour area of long side . There are 3 kinds of layouts of pole that we see everywhere in life

 

① 4 poles mounting

② 6 poles mounting

③ 8 poles mounting
