Indoor lighting should not be too soft or too dark Light and air are the two main factors in judging whether a home is livable. In ancient times, the lighting and gas supply of houses were all derived from the natural environment. Therefore, the ancients attached great importance to the location and orientation of houses, and built the houses as far as possible in a place with sufficient light and atmosphere. With the continuous advancement of human science and technology, in modern society, people can improve indoor phosgene environment to a certain extent through various technical means without completely relying on nature. In the case where the air convection is not ideal, the indoor air speed can be adjusted by fans, air conditioners, etc. In the case of insufficient lighting, artificial light can be used to keep the room bright. Have at least two hours of sunshine daily From the perspective of harmonious living, the ideal home light environment is an organic combination of natural light and artificial light. Both are indispensable. As we all know, sunlight can kill harmful microorganisms in the indoor air; human skin can produce vitamin D after exposure to ultraviolet rays in the sun; sunlight can also prevent the occurrence of rickets in children; can improve human immunity. Experts believe that two hours of sunshine every day is the minimum need to maintain human health and development. In ancient times, people claimed that sunny homes were the “first of Xiangyang House†and the ones that did not have enough sunlight were “homes of shadeâ€. They thought that the former was suitable to live in the latter, and the people were not to live in the latter. At the same time, people also asked whether the residence was sunny and inhabitants. The longevity of life is linked, and the book says: "How do you know that people have longevity, and they have no trouble in daylight?" It can be seen that on the issue that the residence must have natural light, the views of ancient and modern are the same. In the residential phase of selection, it is necessary to carefully examine the lighting conditions in various spaces in the room, and it is advisable to have good vision in the daytime without turning on the lights. To avoid direct sunlight and pay attention to the uniformity of light, half-darkness in the room is a manifestation of imbalance between yin and yang. Some of the interior spaces such as bathrooms and kitchens become “black toilets†and “black kitchens†due to lack of sunshine. The health of occupants is also detrimental. During the renovation phase, many people did not pay enough attention to the design of the artificial light environment. When lighting fixtures were ill-conceived, indoor lighting could not properly match the daily activities of occupants in the room, causing occupants to suffer from eye fatigue and poor vision. Even headaches, physical weakness, lack of energy and other symptoms. The survey shows that 70% of consumers do not know that improper lighting decoration will have a negative impact on the health of occupants. In various cases, the improper lighting of indoor lighting mainly includes the following situations. Light is too strong to stimulate the eye (a) There are too few lights and the lights are too dark. In order to save money, some families are not willing to invest in lamps. On average, only one or two lamps are installed in each space, and the wattage of the lamps is also relatively small, which causes the interior of the room to become dark and makes the eyes of the occupants prone to eye fatigue. Melancholy emotions. (b) too much lighting, light glare. 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 shops, restaurants, and hair salons, and that homes need 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. Dark contrast should not be too obvious (C) Single light source, too much cold light. Home color is divided into cold and warm, home lighting is also divided between cold and warm. In the home to create a warm and comfortable atmosphere, in the lighting should follow the principle of warm colors, cold colors as a supplement. As long as the warm light source and the cold light source are matched properly, besides satisfying the indoor lighting, the home can be filled with a harmonious, peaceful, warm and even romantic atmosphere. Some people prefer cool colors and use cold light sources in their homes to form a serious, cold style. I believe that not many people like this kind of atmosphere at home. (d) improper use of lamps and lanterns, light and dark contrast 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 lighting is to be "dark in room" (e) Colors are messy and stimulate nerves. In order to create a romantic and warm atmosphere, some young people use some lanterns during decoration. Commonly there are pink, blue, purple, yellow, etc. These people do not consider that various colors will affect emotions. Home is not a stage. The color of light should not be too cluttered, otherwise it will make people feel excited and live for a long time will lead to irritability. (6) The intensity of indoor illumination is not divided. In homes, there are different requirements for different indoor spaces due to differences in the use of functions. The ancient geomancy school put forward the principle of “darkness in the room and office,†meaning that the illumination in the living room, study, restaurant, etc. is better than that in the bedroom, kitchen, etc. This design lighting is more in line with the law 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.
