The role of the square illumination light at night, light makeup points every corner of human activities, it is one of the elements of human life, bringing joy to people and beautifying the night. From the perspective of people's requirements for lighting, it can be roughly divided into the following 7 points: Visibility: sufficient illuminance must be provided to provide the basic needs of people's vision; security: lighting is a powerful means of crime prevention at night, poor lighting Places are often high-risk areas of crime rate, people have a sense of security in a well-lit environment; orientation: at night, people tend to have light; therefore, light guides people's direction of action; value: lighting can improve The image of a city and a building is a very effective means of advertising; iconic: buildings have their own unique personality, lighting helps to show the structural characteristics of the building, and even the inherent functional connotation; it also helps people The determination of its location at night; ambient atmosphere: the light attracts people's attention at night, through the lighting arrangement, can produce the desired environment; entertainment: lighting can create a variety of shapes, colors, to give people a joy.
In the outdoor space lighting concerned in this paper, the lighting requirements of each area can be summarized: basic lighting elements (1) average illuminance: in general, the average illuminance of the square should not be too high, too high illuminance choice will lead people In the visual excitement and tension, it is impossible to achieve physical and mental relaxation. Internationally, there is a recommended illumination for square lighting. Considering that Chinese people have strong requirements for lighting, the design illumination should be slightly higher than the recommended value; the horizontal illumination recommended by the square and the horizontal illumination (lx) recommended by the actual illumination (lx) Floor plaza, grassland 510 avenue 1020 main entrance 2050 (2) brightness (illuminance) distribution: at night, due to people's line of sight is constrained, the original layout of the square and the environment often become less clear. In addition to providing the illuminance that people need, the lighting has a stronger role in attracting people's attention. Therefore, the distribution and variation of brightness is very important, it can interpret the layout and atmosphere of the original landscape, while also creating its own landscape effect. According to the layout of the square, the key and targeted lighting is selected to produce effects such as 'light island', 'aperture' or even 'light dot matrix', which can express the landscape design requirements; (3) color temperature: color temperature mainly affects people's Subjective feelings, such as warm and cold, far and near, size and other feelings; in general, in the square lighting, lighting should be the most suitable for warm light source, in some key lighting, a small amount of concentrated use of cool colors; (4) display Color: In the place where there are many people, the color rendering of the light source should be greater than 80, in order to give people a good visual experience; (5) glare: the light source should be hidden as much as possible or the diffused light should be selected to eliminate glare; (6) Color and dynamics: Colors and dynamics can create a festive atmosphere, but it will destroy the calm and peaceful atmosphere, so in the square lighting, in addition to the fountain, it should not be used.
Basic lighting indicators (1) Illuminance and illuminance distribution: The average illuminance is about 20lx, the central fountain is focused on illumination, the illumination is greater than 500lx (2) color temperature and color rendering: Hongqiao central square lighting source mainly has PAR lamp, energy saving lamp, QL lamp And miniature metal halide lamp CDM-T, the color temperature is not more than 3000K, the color rendering is greater than 80; (3) glare: the illuminant of the lamp basically adopts diffuse transmission and diffuse reflection light to avoid glare; (4) color and dynamics: The optical fiber was selected for color change only in the small nozzle portion of the fountain.
The regional lighting layout of the Hongqiao Central Square is a semi-circular square space with the arc-shaped building on the northmost side and the greenery on the south side of Xingyi Road. From the main entrance of Xingyi Road, the first sight is a large three-dimensional fountain combination in the center of the square; the square is divided into two parts: the inner paving plaza and the edge green belt. All the two parts are arranged to diverge outwards from the fountain; the outer side of the green belt is a low shrub, which gives the square space a natural end, and the paving plaza naturally extends to the inside of the building on the center line, avoiding the completeness. The circular arc gives a visual sense of closure; the outermost part of the square is a human walkway, which is laid through floor tiles of different shapes and colors, guiding people towards the buildings on both sides of the entrance and passing through the avenues outside the green belt to the interior of the building.
The central bridge of Hongqiao has been carefully designed in the layout process. In the process of dividing the environmental area, the dimension of time is better integrated into the whole pattern, which makes the whole square appear to be quiet and static. The lighting design relies on the layout style of the square. Through the reasonable combination of light and shadow, the image of the square in the night is created, and the effect of moving the scene is created, leaving the viewer with a constantly changing and harmonious space impression.
Specifically analyzing the two parts of the green belt, the semi-circular side green belt is leaning against the building, and its own scale is slightly larger at night. Therefore, in lighting design, the main consideration is to use the light to achieve the scale on the semicircular edge. The division of the building reduces the subjective scale of the building; the low-column garden light KGS100 is used for the lighting, which breaks the routine design of the ordinary garden light, and adopts the ground embedded lighting installation method, so that the light fixture is simple and light in shape, and integrates with the environment, avoiding Unnatural area separation occurs due to discontinuities in the visual space due to the arrangement of the luminaires. The electrical parts such as the light source of the luminaire are embedded in the underground, and the upper illuminating beam emitted by the light source is reflected by the diffuse reflection surface of the top to obtain soft and natural, non-glare light. The light source adopts Philips QL lamp, which has high light efficiency and good color rendering.
