Urban lighting: a mirror of urban civilization"

With the emergence of electric and electric light sources, with the increasingly rich lighting products and lighting technology, urban lighting, especially urban landscape lighting has been an unprecedented development.

Urban lighting is the conscious use of light, the use of light began to fire, the use of today is the lightning. The use of fire and fire is one of the symbols of human from the animal, and the city of human by the brutal era into the era of civilization, so that there is a close relationship between human civilization and lighting. In the era of the long flame, the main function of lighting is to eliminate the darkness to meet the security needs of people, there is no systematic, large and stable urban lighting, not to mention the landscape lighting. With the appearance of the electric and electric light sources, with the increasing of the lighting products and the progress of the lighting technology, the urban lighting, especially the urban landscape lighting has been developed unprecedentedly.

Today, city lighting has not only the function to maximize the people get rid of the darkness, the effective extension of life cycle, and in the beautification of the city, is playing an increasingly important role in improving the quality of life and city grade. With the development of lighting technology, the increase of the light source and the increase of control means, we can control the lighting more powerful. We can use the art of art, the light as a language to express his feelings for the city; we can use the light as a universal tool to sculpture their own city. In people under the control of light can shape the image, rendering the atmosphere, focus, reconstruction of space, decorative environment, so, under the light of the beauty of the city, is not a simple continuation of the sunshine city beauty, but it is the sublimation and re creation.

Urban lighting can show people the beauty of the city that can't be expressed in the sunlight. As a result, the level of urban lighting directly reflects and reflects the degree of civilization of the city.

Problems of urban landscape lighting

At present, there are some problems in the urban landscape lighting, such as LED abuse, light pollution, and other psychological problems:

First, some landscape lighting obviously did not follow or even deviate from the basic principles of aesthetics.

Landscape lighting design is a kind of artistic behavior, its ultimate appeal is to make the audience and the formation of physical and mental pleasure of the United states. Due to the ability to accept and absorb information is limited, so, people in the perception of objects, will transfer to the object according to their own experience of information choice, only when the object information in the information acceptance range, and in their experience, talent desire to perceive and accept, or reject. We see some of the city landscape lighting, or too many bright spots, the focus or the central point is not prominent or even, or show the pattern, color inexplicable, so it failed;

Second, landscape lighting is not systematic enough.

System is a collection of elements that influence and restrict each other. City landscape is a picture of the system, a relationship of mutual influence and restriction between the elements of the picture such as streets, squares, buildings, green belt, Waterscape, sculpture, landscape lighting task is to dig and the performance of these relationships can cause pleasure by special means. Unfortunately, we see quite a few landscape lighting is not the case. For example, the optional cut a square into isolated parts, not any acceptable explanation part, let in the audience, or at a loss. The evaluation is: Yes, it was very dark, and now very bright; before there is no light, and now not only a lamp, but also a color lamp. This is probably the most ironic evaluation made to the city landscape lighting;

Third, the landscape lighting activities are putting the cart before the horse, the means and the purpose of confusion.

Illumination is the use of the characteristics of light to illuminate the object, in order to facilitate the identification of objects, therefore, lighting is a means to identify the object is the purpose. But in some landscape lighting, we can not see, can not see the face of the object, only to see the lights and the various changes in the lights, landscape lighting on the alienation of the lights and lantern show.

On the art of road lighting

In the field of urban lighting, there is a misunderstanding or blind spots, that is, the relative neglect of a specific area, a specific road exterior appearance. We have the feeling of the current city, thousands of city side, in fact, this feeling is not only from the convergence of all the city's night scene, but also specifically from all the city's road lamp shape serious convergence. Our city, no matter where it is, and whether it is large or small, stands on the road, from the structural form to the material color are extremely simple and the same. The logic behind this phenomenon is two:

First, economic logic. The logic that the standardization and scale of the production cost is low, high efficiency, the simpler the better;

Second, the functional logic of street lights, the logic that the street lamp is simply a functional lighting tools.

In fact, the street lamp is one of the important elements of the city, when we think that the essence of the beauty of the city lies in its unique culture, we should not neglect the art of street lamps. The people living in the city, most of the street and undoubtedly every day they look simple convergence street also cannot meet the needs of beautifying the city, can not meet the psychological needs of the public increasingly enhanced. The artistic level of street lamp modeling reflects and reflects the respect and satisfaction of urban managers to the psychological needs of citizens.

In fact, there are certain cultural connotation street, can not only increase the beauty of the city, also can enhance the city's sense of belonging pride, some also became the city name card, so we should not only ignore the art of street lamp. And should be highly concerned and valued.
