1. project summary

Tangshan nanhu ecotourism scenic spot is located in the center of tangshan city, with an overall planning area of 30 square kilometers, of which 5.4 square kilometers are core scenic spots. After years of ecological transformation, the lake has formed a lake surface of 11.5 square kilometers with 133 different landscapes. The south lake light show a period of public art projects around longquan bay area of 3.6 square kilometers of red phoenix in morning chaoyang square as the spindle, tang gu and amorous feelings of the garden as the two wings, in the main, wooden footway as two ring, south lake avenue and build way as two lines, the formation of one axis, two wings, two rings, two lines and the overall design of the ten architecture, south lake skyline, connect with the beautiful scene in the world water day.

2. the design concept

Her wings

The design of the biggest highlights of the light show - the phoenix wings, see red phoenix in morning sun copper mold, urban planning exhibition hall and the number one on the three are linked together, like a phoenix flying, through the deduction of stage lights, like a phoenix wings flying, longshan fengshan YunFeng island is linked together, the lake and the ground like the Milky Way stars, let all the visitors feel the hero city of tangshan grand and warm.

The most beautiful tangshan, most recall the jiangnan

The most beautiful tangshan, most recall the south lake, described as the south lake landscape space. Nanhu in the hearts of tangshan people, has a special significance. When night falls, stroll in the bank of south lake, water surface, wooden plank road, lake landscape and two mountains and an island (two mountains namely longshan, phoenix tower, an island namely yunfeng island), constitute the upper middle, far near, distinct spatial sequence. Distant mountains and water scenery scroll, through the light to get aesthetic expression. Nanhu landscape temperament, is close to the nature, into the light of life.

3. Project implementation

3.1. Construction area

The whole design cycle is nearly three months, starting from August 15, 2018. Construction area of about 5 square kilometers, with two wings, a shaft include 1 square outside the chicken feather, tangshan urban planning exhibition hall, red phoenix in morning sun, domestic garden sculpture, the longshan and longshan pavilion, a total of 31 city garden, sculpture garden, the designer, the kingdom of candy, the international garden ten ZhanYuan, ring longquan bay, YunFeng island, phoenix palace, south lake avenue, build way, etc., a total of 53 size nodes.

3.2. On-site light test

Carry out on-site lamp test for each installation method in each area, determine the practical lamp parameters in each area, carry out lamp test for several times, strive for perfect design effect, and finally determine the effect of three installation methods.

 Test lamp for installation of vertical pole

Number of lamps per pole: 6 sets of poles distance: 15m; Angle: 40 °

Color temperature: 5700K:2200K:G(1:1:2) control mode -DMX512

Hold the tree installation way to test the light

Each tree :2 sets of lamps: Angle: 40 degrees color temperature: 5700K:2200K:G(1:1:2)

Control mode: DMX512

Floor mounted test lamp

Number of lamps used: 4 sets: Angle: 25 ° c color temperature: 3000K and 5700K:2200K:G(1:1:2)

Control mode: DMX512

3.3. On-site installation

Vertical pole installation, each light pole 6 sets of lights, Angle of 40 degrees, using 5700K:2200K:G (1:2:1) color temperature ratio, DMX512 control, pole height 4 meters, step lamp spacing 15 meters.

The installation method of tree hugging adopts ourijie flexible hoop, the installation method of buckle belt is simple and easy to use, and the automatic size adjustment function does little harm to the trees. Each set of lamps is equipped with stainless steel wire safety rope, which is installed in the bionic bird's nest with beautiful and natural appearance, and high light utilization ratio. The color temperature ratio of 5700K:2200K:G (1:2:1) is adopted.

Floor installation, using the light distribution Angle of 25 degrees and 40 degrees, color temperature of 5700K:2200k:G(1:2:1) can better adapt to the needs of light distribution in various environments, floor installation and high degree of integration with the environment, convenient installation and maintenance.

3.4  Realization of power supply and control

Yunfeng island cloth grade control chart

The installation of the pole adopts the power supply mode at the bottom of the lamp pole, and the four-core control and power supply of the lamp is 3.5 meters, so as to reduce the number of outgoing wires. One power supply is used for every three lamps, and the spacing of each lamp pole is 15 meters. Floor installation power supply instead of independent junction box AC220V power supply, safe and easy to maintain, tree hugging installation adopts the method of up tree wiring, the bottom of which is not safe and reliable, the wires all use bionic cane pipe to hide the thread. Each wiring is standard operation, hot tin treatment three - layer wrap

This time, two control wiring methods are adopted. All the pole lamps are numbered before they leave the factory and are installed in sequence on the site. The signal wires are connected in parallel at the bottom of the lamp poles, and only the signal input ends are used to avoid the problem of multiple wrong connections. Tree holding installation and floor installation by hand installation, can avoid the linear installation of short distance problem. Fiber optic communication is used for fast and stable communication between sub-controllers, and then the regions are concentrated in the switch to enter the control nodes and then enter the main control room.

3.5 Effect debugging

In order to ensure the perfect design effect, the lighting Angle was precisely adjusted after the installation to ensure that the light of each set of lamps was fully utilized to reduce the glare effect. Over 10,000 sets of lamps were adjusted by five working groups and three nights overnight to ensure the progress of the project as planned.

4.effect display

After more than two months of "dressing up", the lighting ceremony was held on the evening of September 30, 2018. During the National Day period, more than 900,000 people poured into the park to visit and play, which was reported by CCTV and other major media. When night falls, music starts, lights dance and the whole nanhu is picturesque. Tangshan opens a new era of nanhu.

5. the summary

After the completion of the project, the implementation of the lights, caused a very good response, to the tangshan nanhu scenic area's popularity and tourism has brought a significant increase, has been recognized by the owner and the design and other parties, thank you for the strong support of the cooperation units, we will continue to contribute more excellent works.
