Indoor lighting selection should pay attention to health

People always like to place a fluorescent lamp on the bedside table, but they have the disadvantage of splash screen. After a long time of use, its distilled gas will make a buzzing sound. In this environment, reading books, playing tablet computers, etc., and performing visual operations will cause harm to the human body. Such as vision loss, dizziness, insomnia and so on.

Over-fitting

Excessive home improvement also means that the decoration is too luxurious. No matter the material used in the materials used in the home furnishings is too complex, it gives people a visual pressure, and at the same time it lacks science in using the lights. For example, the light source is too bright to pay attention to the spectral distribution, making the indoor environment bluish or reddish, which is also light pollution. This kind of environment is easy to stimulate the visual, causing emotional irritability.

Home is a private space, and its use of features requires that night lighting should not be as bright and bright as shopping malls, specialty stores, etc. Home needs more moderate and moderate light. However, there are often people who are pursuing bright and brilliant decorative effects and use a large number of chandelier, spotlights, downlights, etc. The result is too bright light to cause great irritation to the eyeball. If the home decoration also uses a lot of reflective materials, it is strongly Reflected light has a greater harm to human health.

The lighting contrast is too strong

The indoor lighting should be as soft, uniform, glare-free, and shaded as possible. In order to create special effects in certain spaces, some people use lamps with opaque lamp shades indoors, which leads to bright and dark interiors. When people's eyes turn from bright areas to dark areas, it takes some time for the eyes to see objects in the dark areas. This can easily cause visual fatigue.

Indoor brightness is strong or weak

In homes, there are different requirements for different indoor spaces due to differences in the use of functions. The ancient Kansui school proposed the principle of “darkness in the room and the dark room”, which means that the brightness of the living room, study room, restaurant, etc. is better than that of the bedroom, kitchen, etc. This design lighting is more in line with the laws of human life. If the light intensity of all indoor spaces is the same, it will cause inconvenience to the daily life of the occupants.

Professor Randy Nelson of the Ohio State University also found that excessive exposure to light at night may cause depression.

In addition, according to British media reports, people are more likely to develop obesity in brightly lit cities. The reason is that under nighttime lighting in the dark will change the metabolic laws, even if the appetite does not change, it will increase weight.

Ignore color temperature

Neglected light damage in industry analysis

Since designers and salesmen are not credible, where should people reduce light pollution? Zhang Jian, member of the Committee on Interior Lighting of the former China Lighting Association, who has studied for many years in the lighting industry, said that because China is still in a developing country, it has just become wealthy. People generally have a consumption concept that “the more expensive, the better.” This concept does not apply to the field of lamps.

Below is the light that lurks around you

For laymen, they only focus on power and shape when selecting lights, but often ignore the most important color temperature and color rendering index of lighting.

The results of research conducted by the Vision Research Laboratory show that human vision is most often used in sunlight, and sunlight consists of red, orange, yellow, green, blue, and violet. Good lighting should have these same elements. The color temperature of natural light is 6500K, but the color temperature of light is not enough, and the chromatogram should be comprehensive, so as to ensure that there is no deviation in color rendering.

In terms of color rendering index, sunlight is 100%, incandescent lamps are 100%, fluorescent lamps can reach 90%-95%, and LED lamps are 70%-80%.
