Specification for design of Gymnasium lighting

The new technology international sports lighting

Change 1 standard

1.1 football field lighting standards

2011 International Football Federation FIFA the promulgation of the new "football" [1] standard, which is the ninth chapter of sports lighting.

The illuminance value to maintain illuminance value;

.

Ev is the vertical illuminance in the direction of a fixed camera or a field camera, and a hand-held camera and a rocking arm camera are collectively referred to as a field camera;

Each grade in the field of glare value should be GR less than or equal to 50;

The maintenance coefficient of not less than 0.7;

The recommended constant lumen technology.

Need to show that the standard has been involved in the preparation of football developed countries, these countries football game level and the system is very perfect. The "domestic competition" in the table III is close to the "professional competition" in our country, and the "League and club competition" in the second level is similar to that of the amateur competition and professional training in china.

1.2 track and field lighting standards

The new standard international Athletics Federation IAAF promulgated in 2008, namely "the IAAF athletics facilities manual" 2008 edition of [2], the 5.1 section is about the sports lighting.

The level in the field of glare value should be GR less than or equal to 50;

The camera end point, end point line before and after the range of 5m U1 and U2 should not be less than 0.9;

The in the table is the minimum illuminance value maintained average illumination value of illuminance value should not be less than 1.25 times in the table of illuminance value.

And football is similar to that of the international standard track and field is compiled by developed countries, the track and field grade game perfect. Table 2 the third grade of "domestic and international games" although not televised, but it is a professional game, and our "professional game" grade II level "approach; club" is a low level of competition, which belongs to the amateur game, and China's "amateur competition, professional training level of similar.

The new standard for lighting 1.3 International Lighting Commission

CIE CIE 169th [3] - "technical documents for practical design standards" sports events and TV photography lighting promulgated in 2005, Document No. 169 document should be issued in 1989 and [4] [7] combined with CIE83 file read, file No. 83 of many technical content is still valid. 169 document pointed out that the CIE83-1989 file shows the level of lighting suitable for modern CCD-HDTV camera system.

North American Lighting Engineering Association IES IESNA in 2009

RP-6-01 file, the relevant parameters of sports TV relay lighting and country CIE

169 file is consistent, which shows that due to high definition TV, CIE

83 the relevant parameters of the file still apply.

1.4 baseball and softball field lighting standards

American baseball and softball is relatively developed, occupation level is high, the baseball field lighting is a leading international standard. 2009 revised "sports and entertainment venue lighting" [5] standard IESNA

According to RP-6-01 R2009, the general color rendering index, whether it is on standard TV or high definition TV

Ra = 65, temperature

Tc=3000K~6000K.

2 new requirements of lighting layout

2.1 football field lighting luminaire-distribution-style

International Football Federation FIFA 2011 edition of the "football" standard of football field lighting layout adjustments, the main change is the addition of many lamps can not be arranged in order to protect the region, players and referees, to avoid the glare effect, in particular the following parts can not be arranged lamps:

The bottom line to midpoint as the center, when there is space on both sides of the bottom line of 15 degrees within the scope of the TV; when there is no television at the bottom line on both sides of the 10 degree angle range space.

The center of the site behind 25 degrees elevation goal space.

Taking as the baseline, the area outside the 75 degree elevation and area extending outward to the short side line angle of 20 degrees and the enclosed space, of course, for the comprehensive sports is football sports, first, 2, 3 in the range of lamps can be arranged, but should not be on the football mode.

2.2 way light cloth baseball and softball field lighting

Rod softball field lighting layout has the following requirements:

The baseball field is 6 or 8 lamp rod rod arrangement, softball field lighting should be used not less than 4 bar layout. When the canopy can meet the requirements, it is appropriate to use the canopy installed lamps.

The pole should be arranged in the shadow area outside of figure 2.

The height of the luminaire shall comply with the following provisions:

Minimum installation A1 and A2 lamps on a pole height should be calculated according to formula 1.

Ha = 27.43+0.5d1

1) type, ha, A1, A2 on the installation height of pole lamp, m;

D1 - A1, A2 Pole away from the ground line distance, m;

) 2 B1, B2 minimum installation pole lamp height should be calculated according to formula 2.

HB = d2/3 type, Hb, B1, B2 on the installation height of pole lamp, m;

- D2 by B1 (B2) pole as a line parallel to the straight line, the line and field intersecting line, the intersection with B1 (B2) pole horizontal distance of M D2;

3) C1~C4 lighting lamp minimum installation height should be calculated according to formula 3.

HC = d3/2, HC, C1~C4 pole lamp mounting height, m;

D3 - C1~C4 lighting poles on the farthest distance projection unit, m;

4) lamp post the lowest installation height should not be less than 21.3m.

2.3 other changes

2.3.1 constant lumen Technology

"Constant lumen" early in the 2007 version of the FIFA standard has been recommended as "Constant, English

Illumination lamp technology ", also known as" constant illumination". FIFA 2011 version of the standard continues to recommend the use of the technology. The meaning of the constant lumen is in the light source life cycle, the light source of the light source remains unchanged or in a very small range change.

Therefore, constant lumen is actually light flux unchanged phenomenon. Needless to say, the use of constant lumen technology lamps, can keep the venue illumination unchanged.

2.3.2 light pollution control requirements

Football field lighting often appear light overflow phenomenon, high power field lighting irradiation to the stadium, not only cause energy waste, light pollution and produce objectionable, therefore FIFA on site lighting overflow light proposed to limit the indicator light in the sports field overflow

50m and re outward

200m as a calculation point and measurement point, both the level of illumination, but also to assess the vertical illuminance.
