The lighting configuration in commercial display is designed in the store, and it is the goods he sees that affect the customer's purchase decision, and this visual impression is often determined by the lighting configuration. Then, how can designers create a distinctive, attractive, pleasant and secure commercial space environment through the clever configuration of lighting? First, as a designer, we must first make clear the purpose of lighting design as follows: 1. Improve customers' mood and stimulate their interest in exploration; 2. Different treatments of ambient lighting and exhibits lighting; 3. Try to keep the characteristics of goods in natural light; 4. Use lighting to adjust the imperfect architectural space; 5. Avoid glare and make shoppers feel comfortable and safe in it; 6. Avoid dullness and singleness, and make all kinds of lamps and lanterns apply in a balanced way. 7. Improve the configuration efficiency of lamps and reduce waste. Second, the basic functional requirements 1. Attract customers' attention; 2. Create interesting and dramatic displays; 3. Create a positive shopping environment; 4. Lighting should provide guidance for customers; 5. Make the display plane flexible; 6. The lighting configuration should be coordinated with the plane layout and material application; 7. Comparison between the overall lighting environment and the lighting of key exhibition areas. Thirdly, as the ambient light to illuminate the whole space, we need to consider the illumination of light, the expressive force and decoration of color, the illumination of decorative light, the expressive force and decoration of color and the amount of decorative light. Generally speaking, the more expensive the goods are, the lower the commercial ambient light illumination, the better the expressive force and decoration of the colors of the displayed items, and the more decorative lights there are (see table 1). The customer's first impression is very important. Before the brain has made any decision, the sight has been attracted, and the vivid impression, bright or dark, is the result of customers' comparison of their brightness with the surrounding environment: recommended illuminance (Lux) for specialty stores: extremely low 150, high-end shopping malls: low 150-300, and general stores: generally 300-300. For example, red and orange can stimulate people's appetite, so they are often used in front of food stores. Color plays a very important role in shaping spatial characteristics. As decorative lighting, from gorgeous chandeliers to luminous lamp troughs, they are more eye-catching than their own lighting functions, thus becoming a decorative means to attract customers, making the articles in this environmental space more competitive than the surrounding areas. IV. Technical methods of environmental lighting design 1. In a narrow space, try to hide the lamps in the ceiling; In a spacious space, you should take out the lamp and let it shine to 360 o.2. Emphasizing the wall and ceiling with light will make the small space bigger; If you want to make the big space smaller and get a sense of privacy, you can use chandeliers, or darken the surrounding walls and set off the exhibits with spotlights. 3. Emphasize the ceiling. Illuminating upward light on a light-colored surface will make a lower space appear higher; On the contrary, if you use a chandelier to project downward, the higher space will be lower. 4. Using light to emphasize the light-colored anti-wall will visually extend a wall, thus making the narrow space more spacious; However, using dark walls and lighting the exhibits with spotlights will reduce the sense of spaciousness. 5. Local lighting Local lighting usually includes the lighting of windows, display racks and counters. Local lighting is to emphasize customers' impression on the structure, texture and color of goods. The more expensive the store is, the higher the contrast and requirements for this local lighting are. Because of its flexibility, spotlight is often regarded as the main lamp to complete this kind of lighting. Different angles of the light beams of spotlights will produce different effects. Generally speaking, the light on one side can better reflect the structure, texture and color of an object than the light on the front or back. 6. In short, according to different color requirements, the position (wall or ceiling) and illuminance of lamps, it is the most important task for designers to choose the appropriate lamps. Successful lighting design of commercial exhibition depends on good communication between designers and owners, and various technical methods to ensure safety, visibility, high quality, sufficient and reasonable energy consumption. On the composition of light environment art I. The artistic function of light (I) The origin of light art Sunshine, moonlight, starlight and firelight accompanied the life of primitive people, and the rising sun and the setting sun alternated day and night, and primitive people were born, developed and multiplied under the bath of light. The invention and use of fire brought mankind into a new stage of civilization. Fire is not only used for lighting, heating and barbecue food. At night, primitive people danced around the fire and held torches. Piles of flames reflect happy faces, and strings of dancing torches form the fire snake dragon, which is the prototype of the original light art composed of light in early human beings. With the invention of artificial light sources such as fire, candle, oil lamp, steam lamp and electric lamp, human beings have crossed one civilization stage after another and entered the high-tech era of lighting. Due to the rapid development of artificial lighting technology and the popularity of artificial light sources, people's nightlife has become more and more colorful. As a new visual art form, lighting art decorates people's living space more beautifully. Lighting art has been widely used in modern environmental art design, stage art design, interior decoration and other fields. (2) The artistic charm of light The role of lighting is extremely important to people's visual function, because without light, there is no sense of light and shade and color, and everything can't be seen. Lighting is not only a physiological need for people to see the shape, space and color of objects clearly, but also an indispensable material condition for beautifying the environment. Light can form space and change space; It can beautify the space and destroy it. Different lights can not only illuminate all kinds of spaces, but also create different artistic conception and atmosphere of spaces. In the same space, if we use different lighting methods, different positions, different angles, different lamp shapes and different lighting intensities and colors, we can get various visual space effects: for example, sometimes it is bright and spacious, sometimes it is dark and depressing; Sometimes warm and comfortable, sometimes fidgety; Sometimes it is festive and cheerful, and sometimes it is gloomy and horrible; Sometimes enthusiastic, sometimes indifferent; Sometimes romantic, sometimes mysterious and so on, the charm of light can be described as unpredictable. Under the illumination, people and things will change the light-dark interface and shadow level, giving the vision a three-dimensional sense. If the spectral composition, luminous flux, light intensity, projection position and direction of the light source are changed, there will be various changes in hue, light and shade, shadow, virtual reality, outline interface and so on, which is an important means to use lighting art to render the artistic atmosphere of the environment and set off the character. Just like portrait photography, if the dome light is used for direct illumination, the human face will feel cold, serious and gloomy. If you take the inclined upper half side lighting, then the face is well defined, giving people the feeling of extroversion and shrewdness; If multi-source astigmatism lighting is adopted, it gives people an easy-going and pleasant feeling; If directed by direct light, it will give people a feeling of terror, cruelty and anger. Light sculpture is a new form of modern plastic arts. Some artists use transparent materials such as glass, ice cubes and transparent plastics to make various shapes and lamps. Light comes in from the inside or outside, and through giving full play to the physical characteristics such as transmission, refraction and reflection of the projected light, a gorgeous three-dimensional art is formed. Some artists also directly form colorful light patterns by using lamp materials such as colored light bulbs, light beads, neon lights and optical fibers. The comprehensive art created by combining lighting and music is very popular in modern performing arts and environmental arts. For example, when modern rock stars perform, they use the brightness, color and intensity of lights to make the colors of the whole stage change rapidly, thus making fans intoxicated in a fast-paced dreamlike surreal world. For another example, the combination of lighting and music is also used to render the artistic atmosphere of music fountains, open-air squares, dance halls, skating rinks and commercial buildings. Designers use computers to control the programming of lighting and music, so that the rhythm of music is synchronized with the intensity and swaying of lighting, thus obtaining the comprehensive artistic effect of sound, light and color. Second, the composition principle of light (1) and the three laws of color and light mixing. The human eye can not only produce color vision for monochromatic light, but also produce the same color vision for mixed light. For example, 520 nm monochromatic light can stimulate human eyes to feel green, and 5 10 nm and 530 nm monochromatic light can also stimulate human eyes to feel green; For example, 580 nm monochromatic light can stimulate human eyes to feel yellow, 700 nm red light and 5 10 nm green light can also stimulate human eyes to feel yellow, and human eyes can't feel any difference between them. Color-light mixing in spectrum is an additive mixing. White light or any light in the spectrum can be composed of three primary colors of light: red (R), green (G) and blue (B) in a certain proportion. Grassmann summarized the phenomenon of color-light mixing into three laws: complementary light law, intermediate color law and substitution law. Complementary color law-each color of light has another color mixed with it to produce white light. These two colors are called complementary color light. For example, blue light and yellow light, green light and purple light, red light and blue light can all be mixed to produce white light. The law of the middle-two kinds of non-complementary colors cannot produce white light, and the result of mixing is the middle color light between them. For example, red light and green light can be mixed with orange, yellow, yellow-orange and other colors in different mixing ratios. Substitution law-the same color can be composed of different spectra. As long as they feel similar in color, they can replace each other. For example, color light A= color light B, color light C= color light D, then A+C = B+D; For example, A+B=C and X+Y=B, then A+(X+Y)=C, for example, A (yellow light) =B (red light+green light), C (cyan light) =D (blue light+green light), and A (yellow light) +C (cyan light) =B (red light). This is the law of substitution. It is a very important law in color optics, on which modern colorimetry is based. The mixing law of color and light belongs to additive mixing, which is contrary to the mixing of dyes and pigments, while the latter is subtractive mixing, and its mixing law is completely opposite. (2) The additive mixing theory in the physical theory of three-color light mixing proves that red, green and blue light are mixed in equal amounts to produce white light; Red light and green light are mixed in equal amounts to produce yellow light; Red light and blue light are mixed in equal amounts to produce magenta; Green light and blue light are mixed in equal amounts to produce green light. If the letters R, G, B, Y, M, C and W represent red, green, blue, yellow, magenta, cyan and white respectively, the mixing result can be obtained from the following formula: green light (2G)+ red light (2r) → yellow light (Y)+ red light (2R)→ magenta light (M)+ blue light (2B)→ So it can also be expressed as: 2R+Y=2R+(2R+2G)=4R+2G→2R+G (orange) 2G+Y=2G+(2R+2G)=4G+2R→2G+R (yellowish green) 2r+m = 2r+(2b+2r) = 4r+2b. 4G+2B→2G+B (emerald green) 2B+C=2B+(2B+2G)=4B+2G→2B+G (sky blue) As shown in Figure 45, the two colors facing each other through the center of an equilateral triangle are complementary. The results of mixing are as follows: blue light (2B)+ yellow light (2G+2R)=2B+2G+2R→ daytime blue (2B+G)+ orange light (r+g) → white light cyan light (2B+2G)+ red light (2R)=2B+2G+2R→ white light. G+2R→ white light yellow green (2G+R)+ purple red (2B+R)=2B+2G+2R→ white light word limit of 65438+100000 words, which can't be finished. Contact me if you are interested.
