Application of Visual Modeling Theory in Night Scene Lighting of Chongqing Xiexin Garden Club
Application of Visual Modeling Theory of Lighting Engineering Journal in Yixing Lighting of Chongqing Xiexin Garden Club Li Jiancha Department of Investment, Central University of Finance and Economics, Beijing 100081, China Institute of Architecture Science, Institute of Physics, Beijing 100044, China The club is located in Jiangbei District, Chongqing, with a quiet environment. The entire club is made up of a circular wall, with a large area of ​​3 glazed walls as the outer wall, which has a unique appearance. The shape is beautiful and modern. The roof is exposed by large-span trusses and colored steel roof trusses. It reflects the strength and appeal of the building; the entrance to the building is nearly 8 meters wide. , the layout of the decorative door structure of nearly 14 meters and the night lighting design of the swimming pool. In this engineering design, we mainly introduce the visual modeling theory to guide the night scene design. 2 The visual modeling theory analyzes the relationship between the object scale and the line-of-sight perspective. People look at the buildings at night, and the object scale is from the line of sight and perspective. Judging together, the angle of view is different, there will be differences in distance. Considering the imposing manner, the top shape is also changing, adding vitality to the building. The night lighting decoration of the building not only greatly enriches the nighttime power of the building, but also makes it radiant at night, and can give people a pleasant feeling. The project's night lighting design includes the club's floodlighting design and garden lighting design. The two-part floodlighting design includes the facade lighting design and the roof lighting design; the difference and + change the scale of the object. But people feel that there is a change in size. In general, when the human eye does not move. Ten heart water, 觇, is 60, with the center as 0, the upward vertical field of view is 27; when the eye is moving, the horizontal field of view is 2 vertical field of view 3, down 03.
The ideal vertical viewing angle is 27, and when it is greater than 45, the object image is prone to deformation or perspective exaggeration.
The court asked for lighting. The arrangement of the garden lamp was arranged at night. The vertical angle of view of the plant illumination lamp was 45 valence 0 = 1. Observe the detail.
The vertical viewing angle 27 takes 0=12 to observe the main body of the building. The vertical viewing angle 18 is taken as 0=13, and the overall building is observed.
The vertical viewing angle 14 takes 0=14 to observe the outline of the building. Vertical viewing angle 20 HD = l5, observe the relationship between architecture and the environment.
When taking 15 points, the target is dispersed in the field of view, and there are many interference factors, and only the general momentum of the building can be studied. It is usually used in the study of environmental landscapes, with a focus on moving fields.
When taking 01, it is easy to produce perspective distortion when observing the building, and visual correction is required.
The horizontal viewing angle is theoretically twice the vertical viewing angle. According to the size of the vertical viewing angle, the horizontal viewing angle is suitable for observation as follows. At 1 o'clock, the horizontal viewing angle 90, the horizontal viewing angle is too large, and it is observed in the dynamic; at 012, the horizontal viewing angle 54 is ideal for observing the building main body, and within the gaze center 60 When taking 0=13, the horizontal viewing angle 36, observe the overall building; when taking 0=14, the horizontal viewing angle 28, in the gaze center 30, the definition is higher; take, 15 o'clock, the horizontal viewing angle 2040, the horizontal viewing angle is too small, The vision is more dispersed, and from a horizontal perspective, the research landscape is better.
2.2 Visual Center Analysis The visual center of a building in night lighting is the main part that constrains and dominates the observation object. Due to the different time and order of observation, the similar cohesion and grouping of the objects sometimes form different visual centers. Among the visual centers, the most eye-catching place, commonly known as the eye-catching area, is visually called the fun center, which is the focus of vision. According to the field of view, 50 is the edge of the eyelash in the vertical direction within the gaze range, and 60 is the most conspicuous under the eyelid and horizontally. 2. If the total height is 56 or 13 of the total height, the position is Due to the reciprocal nature of the vision, the center of the field of view is the most sensitive. However, due to environmental influences, the visual gathering is attracted to the center, and the visual space is often stimulated by the volume of light and shadow, enhancing its appeal to form a temporary static, to achieve the purpose of strengthening the present.
3 Visual modeling theory guiding design concept 3.1 Sight line analysis of design concept Sight line analysis is the first step and the most critical step in design concept. Determining the Chongqing Xiexin Garden, the main line of sight and the secondary line of sight on the pedestrian flow route are the basis and premise of applying visual modeling theory.
We mainly rely on this primary and secondary line of sight to determine the visual modeling analysis in light environment analysis and lighting design.
3.2 Design of the light environment analysis In order to reflect and strengthen the Chongqing Xiexin Garden, the music department's distinctive personality characteristics, based on the bottom theory and the right, the visual analysis of the music department, the design uses Chongqing Xiexin Garden, the music department and the surrounding buildings in the night scene According to the previous theory and the distribution law of the fun center, the overall lighting scheme is as follows. The visual focus of the club is the entrance façade and the top surface of the plaque; the visual center is the entrance façade and the top surface joint. 4.
The overall building facade illuminance trends from high to low are on both sides of the entrance façade; the dome top surface is the lower wall. This light distribution can highlight the visual focus and visual center of the building, making the club feel like flying at night.
A contrast between the main body of the building and the ambient lighting is formed in terms of intensity and light color.
The application of lighting design to the light reflects the Chongqing Xiexin Garden, and the music department gives the impression that the people are stable and harmonious, beautiful and calm.
3.3 Club and environment night lighting design According to the above theoretical analysis, the difference between the object size and the visual line distance of the visual line and the line of sight of the visual line does not change the scale of the object, but people have a change in size. Based on this principle, based on the analysis of the light environment of the music department, the following specific lighting design methods are adopted. The entrance façade and the external wall surface contour lighting design take into account the large-area glass curtain wall of the building exterior wall. Therefore, it is not possible to use external floodlighting, and only use internal light-transmitting lighting and contour lighting to deal with it. Considering the actual situation of the building, it is considered to illuminate the white gusset along the upper part of the building to form a white light strip at night. However, in order to prevent the exposure of the luminaire to the daytime landscape, the white gusset is used to cover the luminaire, while the interior is painted white to obtain maximum reflection efficiency, and during the daytime, there is no influence on the landscape. For the treatment of the entrance, two sets of color gussets and a white gusset on the upper part of the entrance are used, and the illuminance is designed to be 300 lux. The high illumination of the entrance highlights the magnificent momentum of the entrance.
In the arrangement of the lamps, the lamps and columns in the garden are combined with two FYML609 buried lights, which are installed obliquely to illuminate the columns to form a white light column, which adds a nighttime rhythm to the whole building. .
According to the unique shape of the roof of the building, the roof lighting design adopts Ding 330400 and 01330250 white wide light distribution metal halide lamps on the front and side façades respectively. The lamps are arranged on the roof and the 5 ç› 701000 floodlights are used on the back. , placed on the ground to evenly illuminate the entire roof truss and the lower edge of the roof, so that the roof produces an upward momentum to reflect the characteristics of the building. Since the night illumination of the entire building focuses on the entrance of the building and the chord and roof truss of the roof, the same illuminance 3001 is used, and the luminaires are arranged on the roof platform, completely avoiding the influence of the luminaires on the daytime landscape of the building.
Lighting design of the Garden Square From the functional point of view, the Association, the music department and the garden are casual places, so the lighting should be designed to meet the needs of the people who stay here during the emotional and activity space. Should pay attention to strictly limit the impact of glare on pedestrians and vehicles. This square is Wuxi Square, so two groups of 3 floodlights are used to illuminate the roadway, and 4 sets of floodlights are used in the parking square. The lights are used to evenly illuminate the ground, while the exposed light stand is designed with a combination of light box advertisements. In addition, lawn lamps are arranged on the lawn, and 1 and 102 lamps with diffuse reflectors are used to reduce the brightness of the lamps to avoid the influence of uncomfortable glare on people.
At night, the plant is illuminated, and the plants are illuminated with buried lights on the roadside, and 1609 lamps are used. The light source is a green gold lamp. Make the plants more mysterious and enchanting pool lighting at night. Called, 13531501 from the outside set the floodlights to the pool surface. It creates a nighttime view of the sparkling light.
The total power consumption of the whole scheme is about 25. The energy consumption is low. 4 Conclusion The implementation of this scheme not only satisfies the expected design effect well, but also brings a brand-new nighttime landscape effect to the Club Garden Club. The landscape during the day was basically not destructive, and received a good visual effect of more than one group. Architectural visual modeling. City University of Science and Technology. 1992.
