How to choose office lamps?

The office is the place where most office workers spend the longest time, which is comparable to a second home. In the office, people usually need to engage in close-range visual work for a long time. Long-term exposure to computers or copywriting will lead to excessive eye strain, so the right office lamps is important. Good lighting can make workers feel the greatest comfort and improve work efficiency. The so-called "good" lighting means sufficient lighting so that people can clearly see documents printed, handwritten or displayed, but will not cause eye discomfort due to excessive light levels. So what factors will affect the lighting of office lamps?

Three major factors affecting office lamps

1. Illuminance

Illuminance is a parameter that describes the luminous flux irradiated on a unit area of a surface. It is a unit that reflects the intensity of light, and the unit of measurement is lux (lx). According to the national standard GB50034-2013, in ordinary offices, the standard value of illumination on the work surface is 300lx, and the illumination of the background area of the work surface should generally not be lower than 1/3 of the illumination of the adjacent area of the work surface. In layman's terms, the illumination of adjacent functional areas should not differ by three times. In addition, lamps should be arranged reasonably to make the illumination uniform. The illumination uniformity of office lamp should not be less than 0.6 (illuminance uniformity refers to the ratio of the minimum illumination on the specified surface to the average illumination).

2. Brightness

Brightness refers to the luminous intensity of the light source and can be directly felt by vision. Simply put, it means "how bright a place looks". A good office lamp needs to provide appropriate adaptive brightness to ensure the comfort of the human eye. A certain uniformity must be ensured between illumination and brightness.

3. Color temperature

Color temperature is a unit of measurement that indicates the color component contained in light, and the unit of measurement is Kelvin (K). Too low color temperature will make people sleepy, while too high color temperature will make people too excited and may also cause blue light hazards. Therefore, in office lamps, it is generally recommended to use neutral light, that is, a color temperature light source of about 4000K.
