Traditional stadiums usually use 400W halogen or sodium lamps, although cheap, but not durable, and very power-intensive, life is not long, but also to maintain. With the development of LED lamps, many courses now use LED lamps, a 150W LED lamps can completely replace 400W halogen lamps, more than half of the energy saving. LED lamps and lanterns not only save energy, but also life up to 50000 hours, no stroboscopic when working, that is, on and on, greatly improving the enjoyment of playing.

1. MECREE Basketball Court Lighting Project
Traditional stadiums usually use 400W halogen or sodium lamps, although
cheap, but not durable, and very power-intensive, life is not long, but also
to maintain. With the development of LED lamps, many courses now use
LED lamps, a 150W LED lamps can completely replace 400W halogen
lamps, more than half of the energy saving. LED lamps and lanterns not
only save energy, but also life up to 50000 hours, no stroboscopic when
working, that is, on and on, greatly improving the enjoyment of playing.
The basketball court is a rectangular solid plane without obstacles. For the
major official matches of the FIBA, the measurement of the court must be
measured from the inner edge of the boundary. For all other matches, the
appropriate department of the FIBA has the right to approve the existing
stadium within the following dimensions: length reduced by 4 meters and
width reduced by 2 meters, provided that the changes are proportionate to
each other. Ceiling or minimum barrier production height is at least 7
meters. (According to my own experience, outdoor basketball court can be
equipped with 6 meters high) court lighting to be uniform, sufficient
luminosity. The placement of lighting equipment shall not hinder the vision
of the players. All new stadiums should be of the same size as the FIBA's
main official matches: 28 meters long and 15 meters wide.

Indoor Basketball Court Lighting Design
Indoor basketball court LED Lights should adopt the following
arrangement:
1.Direct Lighting Layout
(1) Top lamps arrangement of lamps. The arrangement of lamps at the top
is arranged above the site, and the beam is perpendicular to the layout of
the site.
(2) Side lamps arrangement of lamps. The arrangement of lamps on both
sides is arranged on both sides of the site, and the beam is not
perpendicular to the layout of the site.
(3) Mixed lamps arrangement of lamps. A combination of top arrangement
and two sides arrangement.

5. 2. The layout of lamps should meet the following requirements
(1) Symmetrical lighting fixtures should be selected for the top layout,
which are suitable for gymnasiums where low space is mainly used and the
uniformity of horizontal illumination on the ground is high and there is no
requirement for TV relay. As shown in the figure:
（2）Sides lamp arranging should select asymmetrical light distribution

6. lamps, arranged on the bridle path, suitable for high vertical illumination
requirements and television broadcasting requirements of the stadium.
When the lamp is on both sides, the aiming angle of lamps should not be
greater than 65 degrees, as shown in the figure.
(3) A variety of light distribution lamps should be chosen for the mixed
layout, which is suitable for large general gymnasium. The arrangement of
lamps and lanterns can be seen at the top and sides.
(4) Light fixtures with medium and wide beams should be used according
to the arrangement of lighting fixtures. They are suitable for building space
with low floor height, good span angle and roof conditions. They are also
suitable for gymnasiums with stricter glare restrictions and no TV
transmission requirements. They are not suitable for suspended lamps and
building structures with bridle path installation.
The arrangement of lamps in basketball hall should meet the following
requirements
1. Lights should be arranged on both sides of the court with the belt pattern
and should be 1 meters above the competition site.
2. Installation of lamps should not be less than 12 meters.
3. Lamps should not be placed above the circular area within the diameter
of the basket with a diameter of 4 meters.
4. Lamp aiming angle is as low as 65 degrees.
5. The both sides of the basketball court, lights can not be placed directly
into the stadium.
Outdoor basketball court lamps should adopt the following arrangement
(1)Sides arrangement of lamps. The lamps and lanterns on both sides are
arranged in combination with the lamp pole or the construction horse-walk,
and are arranged on both sides of the competition ground in the form of
continuous light band or cluster-like centralized form.
(2)Four corners arrangement of lamps. The lamps and lanterns arranged in
four corners are combined with lampposts, and are arranged at four

7. corners of the playing field.
(3) Mixed arrangement of lamps. The two sides of the mixed layout are
combined with four corners.
Outdoor Basketball Court Lighting Design

requirements
1. No TV broadcast is suitable for both sides of the court.
2. The lamp should not be arranged in the range of 20 degrees along the
bottom line of the ball frame, the distance between the bottom of the lamp
pole and the realization of the site should not be less than 1 meter, the
height of the lamp should meet the vertical connection between the lamp
and the center line of the site, and the angle between the lamp and the
ground plane should not be less than 25 degrees.
3. Under any lighting mode, the arrangement of lampposts should not
obstruct the audience's attention.
4.Symmetrical lighting arrangement is provided on both sides of the site to
provide the same lighting.
5. the height of the lamp should not be less than 12 meters, and the height
of the luminaire should not be less than 8 meters.

Energy efficiency calculation:
1, save electricity costs comparison
According to the calculation of 5 hours per day, 1 days and 365 days, the
electricity consumption is 1 RMB per hour.
300WLED projection light: 0.323 kw·h/pcs x 5 hours 365 days * 1 RMB *

800W metal halide lamp: 0.97 kw·h/pcs * 5 hours 365 days * 1 * 35 sets of

The above calculation shows that the 35pcs 300w LED floodlights are 1
years' electricity saving cost.
The 300wLED projection lamp saves and saves electricity 66% per year
than 800W metal halide lamp: 61958.8 RMB -20631.6 RMB =41,327.8
