Abstract: The quality requirements of modern office space lighting are high. This paper expounds the problems that should be paid attention to when designing office lighting from the aspects of controlling glare, selecting light source, lighting arrangement and control, and lighting power distribution design.

Modern office space is a work environment composed of a variety of visual operations. Reading, drafting documents, operating computer and other office equipment require comfortable, relatively glare-free and effective lighting conditions. Office lighting has become one of the main factors directly affecting office efficiency, and it has attracted more and more people's attention. Therefore, lighting design is an important part of modern office space decoration engineering.
Lighting quality
1. Determination of illuminance level
The level of illumination depends primarily on the needs of the visual work and the economic conditions. China's "Civil Building Lighting Design Standards" stipulates that the general office illumination value is 100 ~ 200lx, and the corridor illumination value is about 50lx. The illuminance value of offices in international developed countries is much higher than that in China. The illuminance recommended by the British Lighting Engineering Society for office lighting is 500-750lx, and the illumination standard for Japanese office buildings is 500-1500lx. The office building of Aoyu Building is a medium-to-high-end office space. For office lighting design, please refer to the English and Japanese standard values. Combined with the national conditions, the office design level is determined to be 350-400 lx, and the illuminance level of the public area of ​​the corridor is 100-150 lx. When the design was completed and the balance was made with Party A, it was raised that the corridor lamps were arranged densely, the illumination was too high, and the problem of energy saving was inconvenient. Since the ceiling height of the corridor is less than 2.1 meters, from the perspective of decoration, the illumination can be visually increased relative to the height of the space, reducing the sense of oppression of the space. For energy saving problems, it can be solved from two aspects: light source selection and lighting control. After the actual simulation of the site of Party A, and looking at the problem from a development perspective, it was finally determined to maintain the original design.
2. Glare control
Glare is the most important factor affecting the quality of lighting. Modern office environments must strictly control glare, otherwise it will obviously affect people's work.
Glare includes direct glare and reflected glare. Limiting direct glare is generally considered in terms of factors such as brightness of the light source, background brightness, and lamp mounting position. The first method to limit the reflection glare is to make the worker not within the specular reflection angle of the illumination source and the eye, and the second is to use a luminaire with a large illuminating surface area and low brightness, or a special illuminating light in the visual direction. Light distribution lamps (such as batwing light fixtures, etc.).
In addition to adjusting the installation position of the lamps according to the station arrangement, the decoration project of Beijing Aoyu Building mainly controls the uncomfortable glare from the selection of lamps. Philips glare-free OA M5 lamp recommended by this design, unique parabolic aluminum baffle fog surface light guide, bat air distribution curve, shading angle 33°, brightness above 67° is less than 20000cd/m, will not cause The glare of the VDT screen protects vision and increases productivity.
