People's physical and mental feelings about the living environment mainly include visual environment, auditory environment and tactile environment, that is, people's physiological and psychological feelings about the environment. For the design of the room, people are the main body of service, which puts forward the concept of green design. At present, the fast pace of society has led to more and more people working around the clock; at the same time, in many homes, indoor lighting is often used even during the day. In this case, the harm of the light to the human body must be paid enough attention.
Scientists have long known that bright light can change the brain's internal clock, while the brain's internal clock can control people's sleep. A recent study has shown that ordinary indoor light can also affect the body's biological clock. Therefore, the “green lighting design†of the home can alleviate people's nervousness and adjust people's nervousness. This is a very beneficial measure. The decoration and environmental protection should start from the design.
Beware of the dangers of indoor lighting
The long-term use of indoor lighting has invisibly disturbed people's biological clocks, thus changing the inherent physiological patterns of the human body. This will not only advance the mature age of human beings, but also make people's circadian rhythm disorder, and then there will be palpitations, chest tightness, and mental wilting. Other researchers believe that the intense light emitted by indoor lighting can cause genetic degeneration of a large number of cells in the human body, causing abnormal cells to increase and normal cells to die.
Working under the light for a long time will not only cause eye fatigue, but also reduce the body's ability to absorb calcium. Because there is a big difference in the nature and intensity of light and sunlight. Natural light contains many colors and wavelengths, while indoor lighting is only yellow, orange, red, and lacks the beneficial ultraviolet light in the sun, so the absorption of calcium is greatly reduced. In addition, the light emitted by the fluorescent lamp has blue and invisible ultraviolet rays, which are likely to cause cancer of the human skin after being excessively absorbed by the human body. To this end, experts recommend that it is best to use natural light during the day, always open the window and let the sun enter the room.
Promote "light health"
Glare often appears in home lighting. It not only exists on the reflection of TV and computer screens, but also causes glare in the placement and selection of various lighting fixtures. Glare, also known as glare, is a poor illumination phenomenon that produces glare when the brightness of the light source is extremely high or the difference in brightness between the background and the center of the field of view is large. It can be divided into direct glare and reflected glare. Direct glare refers to the light of high-brightness light source directly entering the human eye, which makes people feel uncomfortable. A typical example is that when the nighttime sleep, the light is suddenly turned on, and the front will be white; Reflected glare refers to the glare that is generated when a light source is incident on a viewing object. This glare can disturb people's vision and cause bad emotions.
"Light health" is a reasonable, moderate and scientific lighting. It is a lighting environment that promotes conservation, environmental protection, is beneficial to production, and beautifies life. It emphasizes a more scientific lighting method.
"light health" standard
Relevant experts believe that the so-called "light health" includes two aspects. First, the lighting must meet the functional requirements of the place, that is, the problem that people say that the light is not bright, the beauty is not beautiful; the second is that lighting must meet people's psychological requirements. Such as the effect of color temperature and brightness on people's emotions, and the harmony between light and shadow.
1. Healthy light emphasizes brightness and color rendering
From the perspective of functional requirements, if the light quality is poor, it is easy to cause fatigue. For example, the light emitted by the fluorescent lamp of the magnetic ballast produces 100 times of light and dark changes per second. When working in such a light environment for a long time, the human eye is extremely fatigued and prone to myopia, which is also disadvantageous for illumination and photography of moving objects. . In addition, if the computer is used under the light, usually the strobe of the fluorescent ballast and the frame of the screen flash alternately to form a light resonance, which is more harmful to the human visual system.
2. Does the illuminance value meet the national standard requirements?
In general, reading in the dark is easy to have an adverse effect on the eyes. When people are too dark to make their eyes look at what they see or write, people will instinctively approach the target to see the target. Over time, it will naturally change the refractive system of the eye, leading to the occurrence of myopia. .
But the brightness of the light source is not as bright as possible. If the brightness of a lamp, fixture, window or other area is much higher than the brightness of an indoor environment, people will experience glare. Glare can cause discomfort, and serious damage to visual function. Therefore, indoor lighting should try to avoid or reduce glare interference, so that "soft" light enters people's field of vision.
