Avoid a colorful light
Many office renovations use light fixtures and light sources. In order to pursue luxurious decoration effects, they often overlook the need for reasonable daylighting. The lights are designed to be colorful and sometimes seem messy. This has a great impact on health, because the light of disordered colors, in addition to endangering vision, also interferes with the function of the brain's central nervous system. People living under excessive, uncoordinated light radiation for a long time may experience symptoms such as dizziness, dizziness, insomnia, and depression, and may even have elevated blood pressure, palpitations, and fever.
Avoid two, decoration is too bright
In order to make the office decoration look more “magnificent†and to some extent make up for the lack of lighting, some offices prefer decoration with brighter colors in the decoration of the office, and even install multiple mirrors and whitewashed walls in the interior. There are also irrationalities in doing so. Under normal circumstances, the light reflection coefficient of the roof and walls should be less than 60%, and the ground should be 15% to 35%. Excessively bright decorative surface will make the reflection coefficient as high as 90%, exceeding the human body's tolerance range. Exposure to such a highly reflective and colorless environment may cause injury to the cornea and iris, resulting in decreased visual fatigue or visual acuity and increase the incidence of cataracts. At the same time, it will disrupt normal circadian rhythms, induce neurasthenia and insomnia.
For the range of light, the human eye has a certain ability to adapt, the pupil also has a regulatory role, when the light exceeds a certain amount, it will have an impact on people, this we call it "light pollution." So how do we avoid light pollution in our modern office renovation? Sichuan Junshanglin modern office decoration company introduced:
