The night landscape image of the city is an inseparable part of the urban landscape. The nighttime light environment in the city can be achieved not by the accumulation of some light forms, but by the combination of human and physical factors such as light, shape and color. A pleasing artistic atmosphere is a manifestation of cultural temperament. Therefore, in the design process, we grasp the moderate relationship between light and shadow, light and color according to natural, humanistic, historical and other elements, and use the language of light, light painting and light carving to edit the art, through various high-tech light means. The second aesthetic creation of the urban nightscape environment provides necessary and comfortable support for the urban people's nightlife. The improvement of the urban night landscape not only beautifies the city, changes the appearance of the city, but also enhances the quality of the night life of the urban citizens. It is very necessary and inevitable.
1 The meaning and significance of interactive urban landscape lighting design
In the process of interaction between people and the environment, “people create the environment, and the environment shapes the peopleâ€, which is the portrayal of the close relationship between the environment and people. Here, the "interaction" is proposed in response to the phenomenon of passive participation in the indifference and man-made landscape in modern society. Appealing people to start from the environment around them, to integrate people's emotions, to cause emotional resonance through communication, and finally to form an "interactive landscape" with harmonious social relations and harmonious ecological relations. This kind of communication and participation emphasizes the experience experience of the participants, emphasizes the humanization of the design personality, and mobilizes the fusion feelings of people's physiological senses and the acquisition and transformation of information, thus embodying a natural design concept of harmony between man and nature.
2 The role of urban lighting in sensory gravitational orientation and interactive design
Lighting can modify the shape and color in the landscape, enriching the original simple shape, and greatly affecting and changing people's sense of shape and color; it can also bring vitality to the space, create an atmosphere of the environment, etc. Wait. Through the projection, emphasis, reflection, contrast of light and dark, or the real, or virtual, the volume, space and texture are emphasized, emphasizing the effect of softening the space and enhancing the rhythm and rhythm of the space. The experience of engaging the senses, such as vision, touch, smell and hearing, can provoke a series of emotional reflections.
2.1 Visual interaction design
The human body's information perception of the external environment is 87% through visual perception. Therefore, the visual landscape is at the forefront of landscape modeling. The lighting landscape is the main means of presenting the night park landscape. However, at present, the most frequently reflected problems in the appreciation of night scenes, that is, too much emphasis on visual perception, neglecting the five senses of the human body and the process of psychological induction. The visual interaction is through the sense of light and color, the composition of the form, the beauty of the material will make people resonate psychologically, thus forming emotional fluctuations. Therefore, we use light and shadow interactive design, black interactive design and color interactive design to reflect the guiding and interactivity of lighting design in urban landscape lighting.
2.1.1 Light and shadow interactive design. In the minds of Westerners, the earliest they pursued was a bright world. Light has a sacred meaning for them. Therefore, more emphasis is placed on light in their architecture, and a "light aesthetics" is produced. The Orientals are more advocating nature, and the light and shadow as natural elements are considered to be “yin and yang harmony†and “the beauty of harmonyâ€, which leads to the “light and shadow aestheticsâ€.
About light and shadow, it is an art in itself. It is not only the brilliance that is the expression of art. The real art of light and shadow design is natural, human and perfect. The seat of the Harvard University campus square (Figs. 1, 2) uses its own design form to project a light and shadow effect with a design aesthetic through the sun's direct reflection and reflection of surrounding objects during the day. The lighting design in the evening is based on the premise of humanized design. Under the requirements of the site that takes into account the overall night landscape of the campus, the seat design adopts the built-in lamp and the downward illumination, which does not affect the visual and functional functions of the disordered people. Sexual lighting. Emphasizing the experience of “light and shadow-landscape-human†in landscape design, this case is to illustrate the importance of interaction between people and light and shadow, thus reflecting the deep spiritual connotation of “light and shadow aesthetics†and expressing different from modern and colorful. Lighting Design.
2.1.2 Stay in black interactive design . The blackness in the illumination, such as the white space of Chinese painting, is an important part of the picture, and the white space in literature gives people the imagination. "When the white is black, you can receive the effect that Xu is the opposite, the shape and the spirit are ready, and create an artistic realm that is not drawn."
Staying black is also an important part of urban landscape lighting design. In the night scene, the black design is a sustainable design of the space, attaching importance to the integrity and harmony of the environment, carrying out creative imagination and obtaining the refinement and sublimation of the theme. Therefore, only the dark part makes the bright part more conspicuous, and the dark part will make people feel more deep and more connotation.
2.1.3 Light color interactive design. In the visual art, there is light and color. As the first visual impression to give people, light color often has the charm of being first and foremost. When people observe objects, the visual nerves respond to color the fastest, followed by shape, and finally the texture and details of the surface, which vividly illustrates the importance of light color in art design. With the advancement of the times, people's spiritual and material life will continue to improve, and they will increasingly pursue the beauty of color. “Color landscapeâ€, focusing on color as an important component of urban landscape, through the planning and design of color factors in the environment, to represent the regional and personalized urban landscape.
2.2 Tactile interaction design
Tactile sensation plays an important role in people's understanding of things and the environment, affecting feelings and intuition. The texture of the material gives a meticulous feeling; the temperature changes bring emotional fluctuations; the convenience and comfort are pleasant. When considering the participation of the landscape, the landscape is no longer a cold facility, the touch is more real and intimate than the vision, and it gets a more real feeling by touching the target. In terms of touch, due to the difference in landscape materials, it also shows the closeness of the landscape (the closeness of the wood quality, the transparency of the glass, the toughness of the steel, etc.). For example, water is one of the most attractive tactile factors.
3 Humanities common urban landscape lighting design
Today, the design of night landscapes in most cities in China is rarely considered for the details of humanity and interactive venues. The vast majority of designs are only monotonous in function. From the plane, the composition and color on the drawings are beautiful and the landscape is similar. There is no humanity commonality in the city. As today's urban landscape lighting design, we should emphasize the improvement of urban environment, enrich urban functions, improve the relationship between people and nature, strengthen environmental awareness, and provide public interaction space for interpersonal communication through government, society and designers. Provide a platform to create a humanized lighting design that resonates emotionally.
4 Conclusion
The design of modern urban lighting environments has evolved from technical issues such as lighting intensity to designing flexible, versatile, and effective lighting to achieve specific ideas and refine specific ideas to achieve a particular atmosphere and mood. Therefore, interactive urban landscape lighting design will be one of the important development directions of future landscape design. Here, we should deeply understand and use high technology, the application of new materials and the more scientific and humanized rationality, so that people can become more conscious of the participation and interaction of the night landscape, making the urban public space more humane. Up to nature.

We are Manufacturer and Supplier to offer Modular Plugs in standard configurations to terminate modular cords for patching or work area applications. Our Modular plugs can be terminated to the exact cable length needed in order to maintain a neater, more organized installation. The modular plugs terminate twisted-pair cable with 26 - 22 AWG (0.40mm - 0.64mm) solid or 7-strand conductors with an insulated conductor diameter of 0.86 - 0.99mm (0.034 - 0.039 in.). All modular plug contacts have 50 microinches minimum of gold plating over nickel and meet TIA-968-A and IEC 60603-7 specifications.
Modular Plug is the name given to a family of electrical connectors originally used in telephone wiring and now used for many other purposes. Many applications that originally used a bulkier, more expensive connector have now migrated to modular connectors. Probably the most well known applications of modular connectors are for telephone jacks and for Ethernet jacks, both of which are nearly always Modular Connectors.
Modular Connectors were originally used with the registered jack system, which precisely describes how the connectors are wired for telecommunications. The registered jack specifications define the wiring patterns of the jacks, not the physical dimensions or geometry of the connectors of either gender. Instead, these latter aspects are covered by ISO standard 8877, first used in ISDN systems. TIA/EIA-568 is a standard for data circuits wired on Modular Plug&Connectors.
