An introduction to the precautions of office decoration lighting design.
Precautions for the overall lighting design of office decoration Introduction The overall lighting of decoration is often used comprehensively in various occasions to achieve the overall artistic effect. It is beneficial to improve efficiency. For example, in a large room, a combination of a reflective ceiling and a chandelier is often used. The chandelier is hung in the middle of the room to supplement the lack of light in the center of the ceiling. Part of the direct light can also be used to enhance the three-dimensionality of various decorative patterns in the room. feel. An introduction to the precautions of office decoration lighting design.
1. When designing lighting for office decoration, it is necessary to fully consider the wall color, material and space orientation of the office space to determine the lighting waste and light color. The design of light is closely related to the decoration of the three major indoor interfaces. If the decorative materials of the wall and ceiling are light-absorbing materials, the illuminance design of the light should be adjusted and improved. If the interior interface decoration is made of reflective materials. Appropriate adjustment to reduce light waste. To make the light environment more comfortable. The formation of the overall sense of indoor office space does not involve people's perception. People's overall impression of the indoor office space environment is a comprehensive process of movement.
2. The luminous ceiling is developed from the duplex skylight. In order to maintain stable lighting conditions and imitate the effect of natural lighting, lights are installed in the interlayer between the glass ceiling and the skylight to form a luminous ceiling. In a large multi-storey building, the equipment layer is often set up. It is a space formed by combining ventilation, water supply, communication and other pipes with lighting devices, arranged under the floor, and divided by the ceiling and the room. There are two construction methods. One is to install the lamp directly under the flat floor, then use the steel frame as the skeleton of the ceiling, and spread some kind of diffused light-transmitting material on it. to the light-transmitting surface of the luminous ceiling. The other type is to divide the equipment layer into several small spaces, which itself becomes the reflector for lighting, and also serves as the air supply or return air outlet of the air-conditioning equipment, which is conducive to the effective use of reflected light. The conditions to be met are: luminous efficiency. It should be high, the brightness of the luminous surface is uniform, it can be repaired during use, and it is easy to clean.
3. Light beams and light strips, which reduce the broadband of the light-emitting ceiling into a linear light-emitting surface. The light-emitting surface of the light-belt is flat with the ceiling surface, and the light beam is protruding from the ceiling surface. The axis of the light-belt is preferably parallel to the outer wall. , and make the first row of light strips as close to the window as possible, so that the direction of lighting and natural light is consistent, reducing the chance of unfavorable shadows and uncomfortable glare, the spacing between light strips should not exceed 1.2 of the height of the light-emitting surface to the working surface It is appropriate to keep the illuminance distribution uniform. As for the luminous uniformity of the luminous surface, like the luminous ceiling, it is determined by the ratio of the distance L between the lamps and the height h of the bulb to the glass surface. The L/h value of an incandescent bulb is about 2.5 for fluorescent lamps; 2.0 for fluorescent lamps. Due to the small space of the light-emitting belt, lamps are generally not used. Due to the small area of the light strip and the density of the lights, the surface brightness is easier to achieve uniformity. From the point of view of light efficiency, it is hoped to reduce the section height as much as possible, and make the section into a smooth curve. The coefficients are also required to be high.
4. Grid-type light-emitting ceilings, the light-emitting ceilings, light strips, and light beams described above all have the problem of large surface brightness. Compared with the point light source at the same illuminance, the surface brightness of the above methods is relatively low, but if the illuminance of several hundred lux is to be achieved, the luminous surface will inevitably form glare. In order to solve this contradiction, the use of There are many methods, the most commonly used is the grid-type luminous ceiling.
