Scientists have long known that bright light can change the internal clock of the brain, while the internal clock of the brain can control the sleep. A recent research shows that ordinary indoor light can also affect human body clock.Long term use of indoor lighting, the invisible to disrupt the ancestors for people to dial a good biological clock, so that changes in the body's inherent physiological model. This will not only make the human mature at an earlier age, still can make human circadian rhythm disorders, and heart palpitations, chest tightness, spirit is dispirited wait for a phenomenon. Another researcher believes that the intense light emitted by the interior lighting, can lead to a large number of cells in the human body genetic degeneration, so that abnormal cells increased, normal cell death.

Long time in the light of work, not only easy to cause eye fatigue, but also reduce the body's absorption of calcium. Because there is a big difference between the light and the sun in nature and intensity. Natural light contains a lot of color and wavelength, and indoor lighting only yellow, orange, red three color, and lack of sunlight in the ultraviolet, so that people on the absorption of calcium greatly reduced. In addition, the light emitted by the fluorescent lamp with blue and invisible ultraviolet, which is absorbed by the human body after the ultraviolet, it is likely to make people's skin cancer.Therefore, the expert suggested that during the day and the best use of natural light, to often open the windows and let the sunshine into the room; day in office working at his desk, to draw attention to the time to outdoor activities, in order to avoid contracting the modern lighting disease.

When must use indoor lighting fixtures, should grasp the following five principles: the use of a wide range of lighting, such as reading on the desk, lighting should be illuminated to the entire desktop; the use of uniform lighting, this is the place, each part of the lighting should be consistent; to maintain a stable lighting, light source not when the light, and to maintain adequate lighting, which has no uniform standards, that is, the more sophisticated work, the higher the degree of illumination.
