The Choice of Light Poles and Lamps in the Olympic Central Area

As a part of municipal transportation facilities, road lighting plays a pivotal role in improving transportation efficiency, lighting urban roads, beautifying the city’s night scene and enhancing the image of the city. The road lighting in the Olympic central area bears more responsibilities. In addition to the road lighting system must meet the corresponding international standards and meet the requirements of society and traffic safety, it is also responsible for the mission of Olympic messengers, the mission of propagating the Olympic concept and carrying forward the Olympic spirit.

Design principles of road lighting in the Olympic central area

Three Olympic Philosophies

Green Olympics–

Regard environmental protection as the primary condition for the planning and construction of Olympic facilities, and formulate strict ecological environmental standards and a systematic guarantee system. Extensive use of environmental protection technologies and methods to promote environmental governance, urban and rural greening and beautification, and the development of environmental protection industries on a large scale and in multiple directions. Strengthen the environmental protection awareness of the whole society, encourage the public to consciously choose green consumption, actively participate in various activities to improve the ecological environment, greatly improve the quality of the urban environment, and build a livable city.

Hi-tech Olympics–

Closely integrate the latest developments in world science and technology, integrate the national scientific and technological innovation achievements, and hold a high-tech sports event. Improve the city’s scientific and technological innovation capabilities, promote the industrialization of high-tech achievements and their widespread application in people’s lives, and make the Olympics a window to showcase new technological achievements and innovative strength.

Humanistic Olympics–

Spread modern Olympic ideas, show the splendid culture of the country, show the city’s historical and cultural features and the good spirit of the citizens. Promote cultural exchanges between countries and deepen the understanding and friendship between peoples of all countries. Promote the harmonious development between man and nature, individual and society, and human spirit and physique. Highlight the “people-oriented” thinking, center on athletes, provide high-quality services, and strive to build a natural and humanistic environment that satisfies Olympic participants.

Design Principles

1) The road lighting design conforms to the three major Olympic themes of Green Olympics, High-tech Olympics, and Humanistic Olympics.

2) The road lighting design meets the requirements of the “Urban Road Lighting Design Standard”.

3) Combine the shape of the lamp with the environment.

The choice of lamps and fixtures

There are also many factors to consider when judging whether a lamp is suitable for the road to be designed. The first thing to consider is the optical performance of the luminaire, and secondly, the installation and maintenance performance of the luminaire, and the material and cost of the luminaire. In addition, the appearance of the luminaire is also an element that is often considered.

Each road lighting fixture has its unique optical properties, including its optical efficiency, light distribution (light distribution curve), light attenuation (utilization coefficient), etc. When evaluating the optical performance of a luminaire, the efficiency of the luminaire is closely related to the efficiency of the reflector in the luminaire used in conjunction. The efficiency of the reflector depends on the reflector’s design shape, material characteristics, production technology, etc., and must be able to accurately match the light source.

The common material of reflector is aluminum plate. After aluminum is formed, electrolytic polishing and anode oxidation treatment are required (a mechanical polishing process is added when the requirements are higher) to improve its reflection coefficient, corrosion resistance, wear resistance and erasability. Sometimes in order to improve the reflective performance of the reflector, high-purity aluminum (aluminum purity of 99.8% or more) can be used to make the reflector, but it is relatively soft. In order to improve its strength, sometimes a layer of ordinary aluminum is covered on the high-purity aluminum. At present, high-purity aluminum is rarely used to make reflectors in Asia, but it is very common in Europe.

In addition to aluminum, a layer of aluminum can be plated on glass fiber reinforced plastic, plastic or other metals as a reflector, but it is not economical. Aluminized FRP is rarely used as a reflector.

At present, the translucent covers of conventional street lamps are mostly made of heat-resistant plexiglass. The reason for choosing it is that it has the following characteristics:

①Good light transmission performance,

②It is not easy to change color under the action of the sun or the ultraviolet radiation of the lamp,

③Good chemical resistance,

④ It has reasonable impact strength.

The translucent cover of floodlights mostly uses toughened glass, because the wattage of the light source generally used in floodlights is relatively large, the size of the lamp is limited, the light is often too concentrated, the temperature of the inner surface of the cover is high, and the organic glass generally cannot withstand it. Therefore, only tempered glass with good heat resistance can be used. Another feature of tempered glass is that the fragments formed when it breaks are not easy to hurt people.

In addition, glass is also used as a translucent cover for floodlights. The advantage is that the price is cheap and does not change color, but the disadvantage is that it is heavy and easy to break. In some places, polycarbonate can also be used as a light-transmitting cover. Its greatest advantage is high mechanical strength and good heat resistance. The disadvantage is that it will change the color under the action of ultraviolet radiation, the price is high, and the light transmittance is low.

In order to make the luminaire well sealed and achieve a higher level of dust and water resistance, the contact surface of the shell and the translucent cover must be processed finely to ensure that no obvious gaps are left, but also of good quality (that is, good elasticity and not easy to aging) The sealing rubber ring, such as neoprene, etc. In addition, the connection buckle (buckle) between the translucent cover and the shell is also very important, and its quality will directly affect the sealing performance of the lamp.

Through the above comprehensive consideration, in order to adapt to the pavement width of different roads in the Olympic central area, according to the characteristics of different roads, it is necessary to select the most appropriate light source. This requires the lamps to be able to cooperate with more types of light source power and power while ensuring a uniform appearance. Light distribution type.

The selected lamps are mature and reliable products, and are self-contained series, which can meet the needs of different roads.

Lamp selection requirements: All lamps used for road lighting in the Olympic central area adopt light-cutting products to reduce glare. The dustproof and waterproof grade reaches IP65. The reflectance efficiency of the lamp reaches 70%~72%.

The choice of light pole

Light pole shape selection

The Olympic Games is a grand event in the world. The choice of lamppost shape should be a fusion of the aesthetics of various nationalities, an abstract, comprehensive, and international aesthetic, rather than just a country’s own. We can add some of our own elements in the details, but the overall style should be concise and generous, abstract, simple, dynamic and full of youthfulness, modern and cultural, and should be fully integrated with the environment and highlight the Olympic theme. The lamp shape must be coordinated and consistent. It must show the enthusiasm and courage of the World Olympics, as well as the solemnity, stability and introspection in the traditional culture of the host country. Only in this way can it reflect the cultural connotation of the humanistic concept of the Olympics, which is our own and even the world.

According to the overall design concept of street lights in the Olympic central area, the main road and branch street lamp series are suitable for 8 longitudinal arterial roads and 9 horizontal arterial roads. The lamp type of each road must be consistent, and the overall style of all road lamp types must be consistent.

The stadium modeling series are street lights specially designed for the roads around the stadium, which are suitable for planning the entrance and exit of the 3 stadiums: No. 1, No. 2, and No. 5 roads.

The main road and branch street lights are mainly simple lights, which not only reflect the modern atmosphere and sense of movement, but also include the stability and restraint of the traditional culture of the country. According to the characteristics of the surrounding buildings, abstraction makes it fully integrated with the environment.

 

The stadium styling series is divided into the National Stadium Bird’s Nest series and the National Swimming Pool-Water Cube series. According to the structural characteristics of the stadium, it is not advisable to choose too complex lamp-shaped structure. To match the shape of the stadium, the main choice is simple and distinctive lamp-shaped structure, which is in harmony with the surrounding landscape and can reflect the Olympic characteristics.

According to the comparison of the characteristics of light poles of different materials, aluminum alloy light poles and patterned steel poles are more suitable for use in the Olympic central area. The aluminum alloy pole has the characteristics of corrosion resistance, high strength, light weight, good ductility, good surface coloring effect and high color durability, but the height of the aluminum alloy pole is only suitable for less than 10 meters. For street light poles over 10 meters, it can be used with patterned steel poles. The pattern lamp pole is currently at the world’s leading technical level. The finished main rod has a clear pattern, no obvious welds, small and very uniform opening gaps, high-quality steel, high strength, and material saving.

The material of the light pole should be further selected according to the shape of the light pole.

 

The details reflect the humanistic concept

A removable aluminum alloy hand-hole door protective cover is set at the bottom of the street light pole, and the surface can be sprayed with various colors, which is functional and has a strong decorative effect.

Pre-set holes and slots on the light pole, with specially designed fasteners, signs, advertisements and decorations can be hung at any time during the meeting, which has convenient and fast functions.

In addition to the street light cables, a separate 24-hour power supply is provided to facilitate the power supply during special circumstances during the Olympics.

Carrier function of street light

While the street lamp realizes its lighting function, it can also become the carrier of other public facilities.

In addition to hanging signs and decorations, you can also install signal lights, monitoring equipment and other facilities. This reduces the impact on the overall beauty of the environment due to the establishment of monitoring and other facilities, and increases the monitoring range of the security system, thereby ensuring the safety of the surrounding area of ​​the venue.
