Office lighting emphasizes comfort
Compared with other office design elements, lighting is often the most overlooked. However, the use of lighting has a vital impact on the working status and efficiency of employees. What kind of office can meet the requirements of the visual environment?
"It used to be bright, but now it is comfortable," said the trend of lighting development today.
Non-reflective
The first condition for comfort is that there is no glare (also known as reflection). You can place a small mirror in front of the computer screen and sit in a normal posture. If you can see a brighter object or light source from the mirror, it means that there is reflection.
In addition, all light sources should be shielded and glare protected to avoid direct or indirect eye contact with the strong light of the lamp tube or bulb.
Many offices will use strip-shaped or grid-shaped metal reflective partitions to improve, but the lamps are all visible. "A good lamp should be lit, the table is on, but you can’t see the lamp when you look up. Any dazzling light is an unqualified design." For example, a rectangular lamp covered with a fine grid-shaped reflector, the lamp tube is not visible, and the light is softly spilled from the top.
Sitting by the window is often disturbed by the strong light during the day. Put down the blinds and feel that the room is too dark. You can make a small curtain or screen on the lower part of the curtain. The sunlight can shine in from the window without letting the window. The people on the side are disturbed.
Uniform and suitable illumination
Those who have done office lighting research have found that Chinese people particularly prefer a "bright and calm" atmosphere. As a result of the large-scale use of daylight-colored fluorescent tubes, the general illuminance usually exceeds actual needs.
A study in the United States shows that high illuminance can cause discomfort, especially illuminance above 1000 Lux (International Unit of Illuminance), 23% complained that they have been troubled by reflection; the American Society of Illumination Engineering recommends that the average illuminance of general office work surface is 750 Lux. Passing standards.
Some people like to turn off the ceiling headlights and leave only one table lamp to work, which is wrong. "Only fun occasionally, not often," because when the work environment and the visual target have a strong contrast between light and darkness, the pupil dilator muscles of the eyes will contract frequently and tire easily. Therefore, comprehensive lighting and work lighting must be used together during reading to avoid strong Compared.
Experts suggest that the overall lighting of the office ceiling usually does not need to be too bright (more than 500 Lux is enough). Individuals can add desk lamps or desk lamps to increase the illuminance according to their needs. This is a more flexible design.
The light source is stable and does not flicker
Whether the light source is stable or not is maintained on a "ballast" in a white plastic shell.
The ballast is the heart of the fluorescent lamp, and it is also a necessary device. Traditional low-frequency ballasts are easy to flicker and bulky, but because of their low price, they are still often used in office lighting.
The new electronic ballast can improve the flicker problem of the lamp. The lamp can save 30% of the electricity and has a longer service life. Although the price is 2 to 3 times higher than the general price, it is still cost-effective in the long run.
Choose the light brightness according to the suitable place
According to different locations, choosing the brightness ratio of the light source is the trend of indoor lighting. Because ages have different needs for light and shade, it is best to have a switch for each independent space, and the large office area can be divided into several areas to facilitate individual control.
Using natural lighting can save more than 30% of summer electricity consumption. The multiple lighting design used in many meeting rooms nowadays is also in response to the use of multi-functional meeting rooms.
