Editor's Note: Quality lighting quality includes five main factors: proper illumination level, comfortable brightness distribution, pleasant light color and good color rendering, minimal glare interference, correct projection direction and perfect shape. Three-dimensional. (I) The purpose of interior design In the interior lighting design, in order to create a reasonable and perfect design that can meet people's visual and psychological aesthetic needs, and has a functional indoor environment. That is to say, the interior design should make the indoor environment have the use value and appreciation value, meet the needs of people's life, and achieve the unity of the use function and the aesthetic function. (2) Interior design requires that the interior design is limited by time and space, and requires a clear time and space. This time and space restriction is mainly represented by modern architectural style, antique architectural style, local architectural style and foreign architectural style. The trend in interior lighting design is to innovate and reflect contemporary real life. Indoor lighting design must first have practical value, and its content depends on factors such as building type, scale, function of use and indoor environment. The indoor environment is restricted by physical environments such as light, color, acoustic, and thermal environments. (III) The stage of interior design The first stage of interior lighting design is to listen to the requirements of the owners and discuss with the professional staff to fully study the factors affecting the lighting design; the second stage is to make some basic design choices. First determine whether to choose a lighting system or an auxiliary lighting system. The main lighting system includes general lighting and partial lighting, the auxiliary lighting system includes accent lighting and effect lighting, the main lighting system is more functional, the auxiliary lighting system focuses on decoration; the third stage of lighting design is the average illumination of the room. The illuminance uniformity and the illuminance on the work surface are calculated to meet the requirements of the lighting standard. If necessary, the brightness distribution in the room, the contrast on the work surface, and the glare can be calculated and checked. (4) The artistic role of lighting 1. Satisfy the use of functional indoor space due to different sizes and functions, when organizing space according to functional requirements, generally by the level of filial piety, transition, open, closed and flexible processing, but arbitrary The indoor space requires certain conditions of clear vision. In addition to natural light, artificial light can provide lighting conditions with light functions such as luminous flux, illuminance and color rendering, thereby satisfying visual effects and improving work efficiency. In public buildings, commercial buildings, etc., even use lighting as auxiliary lighting during the day, or use the lighting to beautify the indoor environment to achieve decorative effects. The lights set in various parts of the indoor space can also become a composition factor of the interior, and play the role of lighting composition to reproduce the decorative effect. The lighting composition uses the color and color rendering of the artificial light source, the shape of the lamp and the shape of the arrangement to achieve the decorative effect and create a corresponding atmosphere. 2, create the atmosphere of the atmosphere, the color, strength, position, direction and level of changes can be creatively used to express the use of indoor space, structural characteristics and architectural style, especially in line with the requirements of the indoor atmosphere, which is conducive to Achieve the purpose of designing lighting functions. (5) The embodiment of the light art According to the function of the indoor space, determine the arrangement of the light, the type of the light source and the light distribution curve of the light, and make a lighting design. In the plan, the entire space is required to balance the light, and the requirements for individual space are strong and weak. The lighting design unit should not be too much, and many are mixed, which can not reflect the role of lighting art. The art of lighting is embodied by a number of processing techniques, such as the use of light, transmission, reflection and refraction to produce a combination of light and shadow. The light distribution and direction of the luminaire can produce light and shadow effects and three-dimensionality of the light. The form of the luminaire creates an artistic style and an atmosphere of the interior space. The color of each surface in the indoor space is displayed by light. The contrast of the hue, illumination and color of the surface color itself can create an indoor atmosphere. Under the illumination of the light, the surface color will have various changes. (6) The expressive power of lighting The expressive power of lighting is an important factor in the creation of lighting art. The space effect manifested by the light, the use of the light to shape the person and the object, the sculpture or the painting made by the light can have attractive expression and can exert the artistic effect. Due to the shape of the light source, the color of the filial piety, the position and direction, the shape of the indoor space is different, and the shape, surface state and color of the indoor object are different. When these factors are changed, the appearance of the indoor space will change accordingly. Different spatial effects. Under the illumination of light, people and objects not only have a light-receiving surface and a backlight surface, but also have a change from the light-receiving surface to the backlight surface, which can naturally exhibit light and shadow effects.
