How to design lighting in modern interior decoration?

The so-called indoor lighting design is relative to the natural lighting of the indoor environment. It is a design method to correctly choose the lighting mode and the type of lamps according to the illumination required by different indoor space environments, so as to provide good lighting conditions for people, so that people can get the best visual effect in the indoor space environment of buildings, at the same time, they can also get a certain atmosphere and artistic conception, and enhance the performance effect and aesthetic feeling of their indoor space. 1. Characteristics of lighting design 1. 1 artistry means that different lighting techniques and colors will produce various psychological effects. The display of various shapes, three-dimensional sense, depth of environment and different architectural styles all need to produce different effects through lighting design. 1.2 Functionality means that there are different functions in different types of buildings, and different lamps and illuminance need to be selected according to the physiological needs of users. For example, when we read and rest, the lighting is different. At home and abroad, there are recommended illumination standards for various application places and activities based on visual health, brightness distribution values of various workplaces, evaluation grades of various glare, and research data with stroboscopic effect. , for our enquiry. 2. Key points of lighting design 2. 1 Appropriate brightness Human vision is very dependent on the brightness of the surrounding horizon. When the brightness of the environment increases, people's motivation and overall vision also increase relatively; And the possibility of errors is also reduced.

2.2 The distribution of light is distributed in the soft lighting of different planes in the room, which can give the space a sense of comfort. On the contrary, improper or excessive lighting will cause vision damage and fatigue. 2.3 Appropriate reflection control indoor reflection will not cause visual impairment, but it may cause irritation and damage to vision. 2.4 Good contrast correction The importance of contrast lies in enabling eyes to distinguish real objects from the background. In the lighting system, good contrast correction will not cause reflection, even for shiny planes and documents. Even smooth paper will not affect reading. 2.5 Correcting the position of the projection direction of the projection direction lamp is very important for contrast correction. It also affects the distribution of light and shadow. 2.6 Proper shadow state shadow can strengthen stereoscopic vision and guidance functions. The effective combination of scattered light and direct light can produce a good shadow state. 2.7 The light from natural light sources will change when it presents a suitable color during the day. Therefore, artificial light sources can present different colors and light properties to support different lighting functions and situations. 2.8 Natural color correction Only the spectral color in the incident light can be reflected by the object and perceived by the naked eye. Color correction is a measure of the ability of artificial light source to express the natural color of an object. 2.9 Effective lighting environment can affect people's mood and feeling. The feeling of interior and lighting is a subjective and unconscious impression. In recent years, the public has paid more and more attention to the importance of a positive lighting environment in the workplace.

2. 10 Effective control of energy consumption The basic requirement of modern lamp design is energy reuse and saving. At present, there are many solutions to the installation of lamps and the transformation and reorganization of old inefficient systems. 3. Lighting Art Design 3. 1 Lighting Art Design Principles When designing lighting effects, we must not violate the relevant national electrical design and installation codes and fire safety codes. At present, most of the fire accidents in some building decoration places are caused by electrical fires. The main reason is that the lighting effect is overemphasized in decoration design and construction, and lamps are randomly installed to increase the capacitance, which makes the wires seriously overloaded and the temperature rise is too high, leading to electrical fires. In addition, the selection of light sources did not meet the electrical and fire regulations, and some light sources with too high temperature were selected and directly installed on flammable materials without any heat insulation protection measures, which led to the ignition of flammable materials. Therefore, when designing decorative lighting, we must strictly abide by the relevant national electrical and fire regulations, and achieve three principles: reasonable electrical design, guaranteed fire prevention measures and perfect lighting effect. Only in this way can our design be scientific, reasonable, safe and feasible. 3.2 Lighting and Space Environment Art The indoor space environment design is the design of the internal space of the building, which is redefined on the basis of the existing building space scale. Lighting design is an integral part of indoor space environment design. It is based on the actual situation and nature of the object space, using lighting technology and artistic treatment means, which can not only make the indoor space colorful and distinct, but also give the indoor space integrity.

In indoor lighting design, using lighting techniques, such as strong light, weak light, astigmatism, full light, looming, virtual reality, dynamic and static combination, controlling the projection angle can greatly render the changing effect of space. In the simple living room space, use the projection angle of light to highlight the exquisiteness and beauty of furnishings, make full use of light to emphasize the picture and pay attention to personalized ornaments. Clever use of lighting design can change the space proportion, limit the space field, increase the space level and make the space orientation clear. Using the irradiation range of light source, the indoor space with different use functions is divided, and the whole and local, main and secondary parts in the indoor space are reasonably defined. Two points are emphasized here: First, the shape, texture and arrangement of lamps play a role in embellishing or strengthening the artistic beauty of space. Second, the decorative function of lighting is not only related to the shape of lighting lamps, but also integrated with the shape, color and quality of indoor space. When the light shines on the shapes, structures and materials in the room, the beauty of the shapes, structures and materials is expressed through the light and shadow effect.

3.3 Art Lighting Design and Physiology, Psychology and Aesthetics The purpose of establishing interior design functionality is to focus on people's psychology, physiology and aesthetics. Evaluating and measuring the quality of interior design is often determined by the use function of various indoor objects, while evaluating and measuring the artistic level of interior design is determined by function, form and aesthetic feeling. Indoor lighting design and artistic aesthetic design are the main contents of creating a beautiful light environment. Interior aesthetics includes various factors, psychological processes and their complex relationships in aesthetic feeling. Generally speaking, feeling, perception, imagination and thinking are indispensable basic psychological factors in aesthetic feeling. The light source, lighting means and power distribution facilities of indoor lighting should meet people's psychological, physiological and aesthetic requirements. If it violates people's physiological and psychological requirements, even the best technology and function can't be said to conform to humanized design. As the main medium of people and space, light has psychological, physiological and aesthetic functions. The change of light affects the reaction of human cerebral cortex, and visible light has an effect on immune and allergic reactions [3]. If lighting is used, it must conform to the illumination of indoor use area and space. Room area1318m2, and illumination must be 2030Ix. If the illumination is too low, people will feel visual fatigue and even myopia. The solution can be to adjust the lighting mode, change from direct lighting to local lighting, redistribute light, use covered desk lamps, adjust the angle of lamps, rationally arrange lamps, improve the utilization rate of light and ensure the health of eyesight. Especially under the light source of direct illumination, it is easy to produce reflected, direct and flashing glare. Measures such as lampshade and soft light should be taken to eliminate the physiological and psychological effects of improper light. Attention should be paid to limiting the generation of glare. Indirect lighting should be given priority to in lighting, goods can be illuminated by appropriate projection lights, and sidewalks are guided by lights, so that the light environment in shopping malls is well-defined and easy for people to accept physically and psychologically. This fast-paced art form also meets the aesthetic requirements. The color perception of light is not only the working ability of vision, but also an important emotional factor. The physiological function of color lies in its influence on vision itself and its adaptability to visual changes caused by color stimulation. Indoor colors should not be colors with too high or too low hue, purity and lightness. For example, red and green should not be used in the living room. Red will speed up the blood circulation. If you live here for a long time, people will feel hot-headed, nervous and tired. If you live in a green room with low purity, it is like living in a virgin forest. Excessive loneliness and tranquility can make people feel depressed. Therefore, the indoor color should choose the color relationship suitable for people, and you can use the color relationship of middle tone, medium and low purity and medium and high brightness. Therefore, how to determine the quantity and quality index of light environment in indoor color design is very important for grasping the objective object. Rhythm and rhythm, proportion and proportion, harmony and unity, harmony and contrast are formed in accordance with the law of design aesthetics and are in line with people's aesthetic psychology. Similarly, lighting also needs artistic beauty. The distribution of brightness, space, color and shadow around the room is completed in the form of artistic design on the basis of satisfying people's functions. Therefore, lighting design must analyze people's psychological, physiological and aesthetic feelings, make the design closer to real life, and better meet people's physiological, psychological and aesthetic requirements.

With the rapid development of information science, people will have more time to live and work indoors. The focus of aesthetic consciousness of contemporary indoor environment design has also developed from architectural space to space-time environment, that is, the traditional three-dimensional space plus time has become a four-dimensional space, emphasizing people's participation and experience. The status of artistic lighting design in interior design is also increasing. It not only provides good visual conditions for people's work, study and life, but also embodies a certain artistic spirit by using the harmony between the art of "light" and its modeling, color and spatial environment, enhances the artistic aesthetic feeling, and makes the environmental space more in line with people's psychological and physiological pursuits, thus obtaining the enjoyment of beauty and psychological balance, and satisfying the psychological function of vision.
