With the continuous development of urban construction, people’s economic, cultural, and material living standards have rapidly increased. People are not satisfied with merely understanding light as a functional lighting and using it to improve their own living and working environment. Specifically speaking, on the one hand, we must satisfy people's basic living and work needs, that is, the light environment reaches a certain degree of illumination, brightness distribution, and color display and other necessary conditions; on the other hand, people also demand to create a more comfortable and beautiful living space.
In modern cities, artificial lighting has created a magical "night city" for our lives. Artificial lighting not only meets the lighting at night, but also plays an important role in the interior and exterior environment of modern architecture. Shopping malls, hotels, stadiums, stage or other public places, from indoor to outdoor, from shops, restaurants, homes to landscaped streetscapes, brilliant, colorful "artificial lighting" everywhere is showing its charming charm for our Life depicts a picturesque mood.
However, compared to inexhaustible natural lighting, artificial lighting needs to be consumed at the expense of energy. Nowadays, the city has implemented a large-scale lighting lighting project in order to display its own image, create a good light environment for people's lives, promote the development of commerce and tourism, and so on. The use of lighting fixtures is increasing, and the proportion of electricity used in the city's total consumption is also increasing. Rapid economic development requires more and more abundant power supply and consumption, which makes power supply and demand contradictory. The shortage of power supply is difficult to ease in the short term, and both development and savings have become an inevitable direction of economic development. At this point, energy conservation and emission reduction have also become our inevitable choice.
But it does not mean that lighting efficiency is ignored and lighting fixtures are blindly reduced. Nowadays, the status and role of urban lighting is more and more important. Artificial lighting is an important means to expand the architectural aesthetic connotation and improve people's lives and work environment. Faced with the contradiction between lighting effects and lighting energy saving, we must find out their balance points. Conflicts are the unity of opposites. As long as the two parties are in balance, coordination, and cooperation, things will show a harmonious state. The same is true for lighting applications. Only when the effect and energy saving reach a proper balance can the true harmony of beauty and environmental protection be achieved.
To achieve a balance between lighting effects and lighting energy conservation, we must pay attention to the role of lighting design. Appropriate lighting design can make the project reflect a good effect, while achieving the goal of avoiding the waste of “light†energy.
In the lighting design of a project, it is first necessary to determine what kind of effect or theme the project should exhibit, and then consider the illumination design or brightness standard of the lighting design, and strictly follow the relevant standards for design.
Second, we must choose the best lighting. Night scene lighting has contour lighting, flood lighting, internal lighting and other ways. The most appropriate lighting method should be selected according to different subjects to be illuminated, so as to effectively improve the quality of lighting and avoid unnecessary waste of energy. For example, if cast lighting is used in the facade of glass curtain walls, not only energy is wasted, but also there is no lighting effect. On the other hand, if the interior lighting is properly used for lighting, it not only reflects the structural characteristics of the building, but also achieves corresponding The energy-saving effect.
Again, use appropriate lighting products. The selection of high-efficiency energy-saving light sources and high-reflectance lamps is the core of reducing lighting power. There are many light source products, and different product types will have their advantages and disadvantages. For example, the high light output and low color rendering properties of high pressure sodium lamps, the high color rendering and low light output characteristics of incandescent lamps are the key in lighting design. Only by combining the characteristics of lighting products and using them reasonably can they be effective. The best balance in energy saving.
In addition, a reasonable lighting distribution system should be selected to provide a more stable voltage, reduce the voltage offset, ensure good visual conditions, increase the life of the light source, save power, increase the power of the lighting circuit, and reduce the power grid lighting circuit. Power loss.
Vision is the first person's ability to perceive, and the origin of vision is the reflection of light by objects and the reception and analysis of light by visual organs. In terms of human vision, there is no light and nothing. The American architectural designer Louis Kang said: There is emotion, it creates a field that can be united with people, and associates people with eternity. It can create a form that cannot be obtained using general styling methods. In the current shortage of power supply, we must find the balance between lighting effects and lighting energy saving. Only in this way can we continue our colorful lighting.
