The work content of the lighting designer: 1. Collect relevant materials and conduct research and analysis on the spot; Collecting data is the layout, function, and requirements of the owner of the lighting design, analyzing the lighting requirements, such as the illumination of general lighting, Key lighting, local lighting, and safety lighting. If it is office lighting, the uniformity of illumination is more important; and the clothing store requires the layering of lighting. The key lighting is more important. The lighting guides the walking route of the customer and displays the material of the clothing. The exhibition hall should choose different color temperature and color rendering according to the material of the exhibition to prevent excessive temperature and ultraviolet radiation. The contour lighting, landscape lighting, road lighting and night lighting of the building should study the cultural orientation of the city. Planning, overall layout, starting from the whole. Therefore, research and analysis is very important, basically determines the form of lighting, the choice of illumination, the application environment of the lighting; Second, establish a computer model of the design environment, draw a sketch of the design; draw the plane and elevation map with CAD, because CAD can accurately control the size Use 3DMAXS, photoshop to build a preliminary model of the renderings, analyze them in the model, and analyze those areas that need to be highlighted. For example: clothing store, it is necessary to establish a model model, analyze the angle of the light source, form a contrast, the location of the key lighting, the prominent position, the illumination distribution. Establish a model of the room, window, and display cabinet to analyze how the light source is illuminated to get the best results. Third, carry out creative design, draw renderings and lighting design analysis diagrams; to carry out creative design, you need a certain artistic accomplishment and talent, grasp the art of light in place, use light as pen and ink, use light source reasonably, and write beautiful pictures. Analyze the principle of light, master the characteristics of light, and draw renderings in 3DMAXS, photoshop, DIALUX and other software in the computer. This effect is only a simulation effect, and the light of the computer is different from the actual one. Only after the creative lighting effect is satisfied, the arrangement of the light fixture and the choice of the light source can be grasped in the design. Analyze the renderings and analyze how to use the actual lighting to achieve real results. And combine lighting and decoration to achieve functional and aesthetic requirements. 4. Technical design of lighting engineering; Lighting engineering technology design main lighting calculation, lighting selection, light source selection, electrical selection, lighting arrangement and distance. In the lighting design, it is necessary to choose reasonable, suitable and comfortable illumination. According to different occasions, different illumination design can be carried out. If necessary, you can personally investigate, select the same function room, test illumination, compare and analog, you will get the most satisfaction. Degree effect. According to the relationship between illuminance and satisfaction, when the illuminance is below 500LX, the slope of the relationship line is the largest. Above 500LX, the increase of illuminance is slower for the satisfaction, while the person who feels the most comfortable at 1000~3000LX. The national illuminance standard is a comprehensive value, mainly for reference and control. The luminaire is selected to have high luminous efficiency, and the color temperature and color rendering of the light source are selected according to different occasions. Ballasts need to be based on on-site and energy-saving aspects. Electronic ballasts are more efficient than inductors, harmonics are also corrected, but electron lifetimes are relatively short, and they are selected based on their advantages. Selecting the appropriate aspect ratio of the illuminator, the unit installation power also needs to be controlled. Five pairs of lighting electrical products; the choice of lighting appliances should be compatible with the use environment, conditions of use, and priority to energy-saving. The illumination source first satisfies the illumination requirements (illuminance and color rendering requirements), the ignition time, and is selected according to the environmental conditions, and finally considers the investment cost. The ballast is energy-efficient and efficient according to the cost performance and use occasions. 6. Formulate the installation, power distribution and lighting control system design scheme of the lighting facilities; The installation of the lamps should be coordinated with the use occasions. It is also required to prevent glare, reflect glare, and control the aspect ratio of the illuminator. The distance between the illuminator and the wall is not more than (1/2 to 1/3) L (L is the distance between the illuminators), and the installation of the illuminator considers electrical safety. It should not be lower than 2.4m. Select the fixing method according to the weight of the illuminator. General lighting fixtures are arranged in a geometric shape. It can also be grouped according to the style of the building ceiling, formed into a group, and arranged in a surrounding style to form a decorative pattern. Power supply and distribution design: 1. Analyze its load level, reasonably determine the lighting load level, and correctly select the power supply plan according to its level.
2. Calculate the load calculation when using the required coefficient method when calculating the main line and the main line. The corresponding lighting electrical requirement factor of the branch circuit is 1.
3. The distribution of each phase of the three-phase lighting line should be balanced. The end current of the single-phase loop should not exceed 16A, and the luminaire should not exceed 25 when it is a separate circuit. Lighting control, can be combined with natural light source, using group control, zone control, according to different requirements, for the purpose of convenience and energy saving. Seven technical guidance for construction, installation, commissioning and acceptance of the project; During the construction process, it is necessary to go to the site to guide the installation, circuit installation, laying method, control method to meet the design requirements, commissioning, acceptance, if the actual effect is not achieved, Take certain measures to achieve the best results. Eight suggestions for the daily maintenance of lighting projects as lighting designers are to design a reasonable, comfortable, energy-saving and environmentally friendly lighting art. Meet everyone's needs and get a comfortable light environment. It is necessary to continuously improve professional standards and artistic accomplishment, to achieve the best combination of lighting technology and art, to design a light environment that meets the needs of society, to illuminate the world with light, and to illuminate one's own life.
