Light culture, light culture, imagination

introduction

In order to conscientiously implement the spirit of Lichang’s “Integration of Urban Night Lighting Construction into Light Culture”, “China (Tianjin) First Modern Urban Light Culture Forum” was held in 2004, and two years later, “China (Tianjin) Second” was held. Under the new situation, the Modern Urban Light Culture Forum will re-understand the profound meaning of the "light culture" concept, further interpret the "light culture", and explore the profound connotation of "light culture" and expand it.
The extension of Guangguang's Guangbo has far-reaching significance.
The theoretical research and practical application of "light culture" should be the subject of our long-term research and exploration.
On this occasion, the author re-recognizes the "light culture", imagines the "light culture", and interprets the "light culture". If it is not appropriate, please criticize and correct the experts in the industry.

First, "light"

1. Definition of light
Light is an important natural phenomenon. When a beam of light is projected onto an object, reflection, refraction, interference, and diffraction occur. The reason why we can see the variegated and rapidly changing scene in the objective world is because the eye can receive the light emitted, reflected or scattered by the object. Light is essentially an electromagnetic wave that covers a relatively wide range of electromagnetic spectrum (from X-rays to far-infrared), but with shorter wavelengths than ordinary radio waves. The visible light visible to the human eye is only part of the entire electromagnetic spectrum. Light has wave-particle duality, that is, it can be regarded as a kind of high-frequency electromagnetic wave (10 12 ~ 10 15 Hz), or as a particle, that is, light quantum, referred to as photon.
It is well known that light is produced by light sources such as the sun, candles and electric lights. The sun is a natural light source, and the candles and lights are artificial light sources. Since the natural light source available produces only a small fraction of the entire light family, humans have been working hard to develop and utilize a wide variety of artificial light sources. The invention and utilization of any new artificial light source marks a new advancement in human civilization. Born in 1879, American inventor Thomas Edison succeeded in creating the first available incandescent light bulb, creating a new era of human electrical lighting. In 1905, the first successful production of tungsten incandescent bulbs by the Austrian Uster and Hanaman in a backlog was also an important milestone.
2. The meaning of light
Light has a close relationship with human life and social practice. Light is one of the sources of life on earth, the basis of human life, the tool for human beings to understand the outside world, and the ideal carrier or medium for information.
Ever since Prometheus sowed the fire, light has given mankind unlimited hope! In the long history of the river, the sun feeds the earth, and human life is accompanied by light every day. The natural light alternates and controls the human body clock, keeping our life rhythm balanced. Sunlight produces vitamins and many of the so-called unknown nutrients that keep our bodies healthy and healthy. Light stimulates vision, allowing us to see and recognize the surrounding environment and the colorful, colorful world, and get 90% of the outside world information. Bright, warm, active light and invigorating spirit make us psychologically satisfied and happy. When the sun sets and the night falls, people still have a crush on the light brought by daylight. From ancient times, the people of the ancient people took fire, illuminate the caves, the grass sheds, and the high-rise buildings in the modern city. The people never interrupted the search for light in the dark, and walked a long road of "light". . Humans have always pursued the use of artificial light sources to continue their activities, expand the space of their activities, feel their own five-life life, and create the value of their own lives. Light has become an object pursued by mankind. Mankind pursues light, light represents life; light represents hope; light represents advanced; light represents all good yearning.
Therefore, light is a material form and a rich gift from nature to human beings. She satisfies the needs of human existence, life, production and development, and greatly promotes human family life, economic development, technological progress and historical evolution. effect.
Light is a testimony to the development of human history. She coexists with human beings while sharing resources. Through his cultural landscapes of architecture, bridges, villages, factories and mines, urban landscapes, natural scenery, fields, vehicles and roads, she shows her existence and beauty, bringing infinite imagination and spiritual touch to human beings, and creating a “light culture”. .
Light and shadow accompany, inseparable; light and color follow, harmony echoes. Light is a language, the soul of architectural art. Light tells us about the architect's design philosophy and artistic pursuit, and light and architecture and the city symbiosis. It is a design tool and a building material. Architects can use it to create ideals and showcase their talents. Light is another vast world outside the three-dimensional creation of architecture - "Light is the fourth dimension of architecture."
