Comfort is what is emphasized in office lighting
Compared with other office design elements, lighting is often the most overlooked. However, the use of lighting has a crucial impact on the working status and efficiency of employees. What kind of office can meet the needs of the visual environment?
"It was good to be bright in the past, but now it is comfortable," said the trend of today's lighting development.
non-reflective
The first condition for comfort is that there is no dazzling glare (also known as reflection). You can put 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 a reflection phenomenon.
In addition, all light sources should be shielded and protected from glare to avoid direct or indirect eye contact with the strong light of lamps or bulbs.
Many offices will use strip or lattice-shaped metal reflective partitions to improve, but the lamps are all visible, "a good lamp should be, when the lamp is on, the table is on, but you can't see the lamp when you look up. As long as you see Any dazzling light is an unqualified design.” For example, a rectangular lamp covered with a thin lattice reflector, the lamp tube cannot be seen, and the light is softly sprinkled from above.
Sitting by the window is often disturbed by the strong light during the day, and when you put down the blinds and feel that the room is too dark, you can make a small curtain or screen in the lower part of the curtain, so that the sun can shine in from the window without letting the window People on the side are disturbed.
Uniform and suitable illumination
People who have done office lighting research have found that Chinese people especially prefer a "bright and calm" atmosphere. As a result of using a large number of daylight color fluorescent tubes, the general illuminance usually exceeds the actual need.
A study in the United States shows that high illuminance will cause discomfort, especially if the illuminance is above 1000Lux (international unit of illuminance), and 23% complain that they have been troubled by reflection; the American Society of Illuminating Engineering recommends that the average illuminance of the general office work surface is 750Lux as the passing standard.
Some people like to turn off the ceiling headlights and leave only one table lamp working, it is wrong. "It can only be played occasionally, not often." Because the contrast between the working environment and the visual target is strong, the pupil dilator sphincter of the eyes will contract frequently, and it is easy to get tired. Therefore, full lighting and task lighting must be used together when 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 500Lux), and individuals can add desk lamps or desk lamps to increase the illuminance as needed, which 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" with a white plastic casing.
The ballast is the heart of the fluorescent lamp and a necessary device. Traditional low-frequency ballasts are prone to flickering and bulky, but they are still widely used in office lighting due to their low price.
The new electronic ballast can improve the problem of lamp flicker, the lamp can save 30% of electricity, and the service life is longer.
Choose the brightness of the light according to the location
According to different locations, choosing the brightness ratio of the light source is the trend of indoor lighting. Because age has different needs for light and shade, it is best to have a switch in each independent space, and the large office area can be divided into several areas for individual control.
Utilize natural lighting to save more than 30% of summer electricity consumption. The multiple lighting design used in many conference rooms today is also for multi-functional conference rooms.
