2020 LED Cricket Ground Stadium Light Layout Considerations

51 Published by admin 04 29,2020

How to light up the ICC Cricket World Cup Stadiums? Lighting fixtures are one of the paramount facilities for night cricket game. Especially for the international tournament, the lighting requirement is of highest standard. As one of the ICC World Cup Stadium lighting supplier, we fully understand the lighting design principle and standard. Let’s explore what we need to consider before we light up the magnificent stadiums.

Light tower or pole locations

For the large majority of community cricket grounds, the typical design will include a 4 pole design. 6 pole designs are recommended for televised play conditions. They may also be required to improve spill lighting control. A 5m clearance (run-off) zone shall be provided from the playing area or boundary line to any light pole.  As per the Football (All Codes) Standard, placement can be immediately behind a permitted boundary fence.

Pole heights

Adequate pole height is important to ensure good seeing conditions for participants which minimize glare to within prescribed levels and allow light to uniformly distribute throughout the playing area. Pole heights are recommended based on the distance d determined as per the above diagrams.

Non-Televised Venues

For non-televised venues the mounting height is recommended as h = 0.36 x d where:

h = height of the lowest floodlight above the field surface (which may differ from the height above the base of the pole).

d = horizontal distance between floodlight oval centre or major axis through the centre of the oval.

The above corresponds to an angle of 20 degrees to the lowest floodlight from the centre of the oval (4 pole system) or oval major axis (6 pole system)

In any case pole heights less than 25m are not recommended for the lighting of outdoor cricket playing fields.

Class I venues

For Class I venues, consideration should in any case be given to increasing the pole heights to obtain 25 degrees to the lowest floodlight from the centre of the oval and thus h = 0.47 x d
(tan25°=0.47).

This greater height would also be required should a venue wish to upgrade for television broadcast at a subsequent time and would also be required if the venue wished to accommodate football code professional play standards.

Floodlighting aiming

Floodlight aiming angle is generally recommended to not exceed 65°. The aiming angle is the angle in the vertical plane between the line of peak intensity and a downward vertical line connecting the centre of the floodlight to the ground below. Floodlighting designs will often refer to this as the floodlight ‘tilt’.

What are the specifications of stadium lights used during cricket matches?

In general, lighting for outdoor practice or training facilities should follow similar principles as outlined for outdoor cricket field lighting.

Brightness (Lux) Standard

As a fast moving ball sport the lighting illuminance requirements for cricket are generally comparatively higher than for the ball sports of Australian Rules Football, Rugby codes and Football (Soccer) – the seasonal sports that cricket typically shares venues with.

For general practice and recreational cricket stadiums, we need 250 to 350 lux, which is sufficient for players to have mild competition between the team members. Then, 500 to 750 lux is needed for professional matches. If designed for televised watches, the lux requirement of the cricket stadium is approx 2000lux horizontal and 1500lux vertical. Plus, there is a uniformity requirement of 0.65, even 0.7-0,8.

To product such a higher level of lighting, we will need hundreds of 1000W,1200W or 1500W Cricket lights. If for large sports fields with corner poles, do you find it is very difficult to have enough light in the middle of the field or will need more number of lights but exceed the pole bearing weight?

MECREE Cricket lights with high central light intensity will solve the problem for you:

Still gets 1.2lux at the distance of 1000M, good to use for high mast of 25M-100M.

Glare Control

From above content, we know that the glare can be controlled by adjusting the pole position, pole heights and flood light aiming angle, but also select from types of lamp that well control the distribution of light to the playing surface.

MECREE Cricket ground stadium light is with optical reflective cup+ Secondary Optical Lenses and High permeability reinforced tempered glass protection. The secondary light distribution design is adopted to minimize the spill light and glare, The linear light is used many times to effectively reduce the residual light while enhance the central light intensity more than 5 times.

Uniformity

Uniform lighting ensures the eye is not forced to compensate for marked changes in lighting levels through perceived light and dark patches in the field of view during play and is thus able to adequately gauge the trajectory and position of the ball and that of other participants.

MECREE LED stadium lights with different lens angle of 10D, 20D, 30D, 45D, 60D can be mixed angles to adjust to the best uniformity.

High CRI 90

Adopt LED chips with high digital, high color fidelity and no stroboscopic features, which can meet the requirements of 4K, 6K, 8K and HDTV broadcast, greatly improving the audience's experience of watching games and the quality of TV broadcast.
