90% of households, lighting is not scientific

The reporter interviewed 20 people randomly, and also said that when selecting lamps, the main consideration is whether the shape is beautiful, and they barely understand what color temperature is, and they know little about lighting design.

At present, people are paying more and more attention to food safety, happiness index, air quality. At night, we replaced the sunlight with light. Most people only enjoy the light it brings, but they ignore the health hazards that it may bury. From the extraordinarily dazzling neon lights in the outdoors, to the various colors and colors of light in the home, the unreasonable design will also create ubiquitous light pollution. He is like a beautiful invisible killer, always threatening our health.

Jiucheng home lighting is not scientific

At 10:30 in the evening, Ms. Song, who lives in Fengtai District of Beijing, has been slumbering. The red neon lights outside the window flashed and shone through the curtains, making her heart extremely irritated. This situation is very common in big cities.

Not long ago, the flagship store of Apple in Hong Kong was still brightly lit after being shut down at night, and was accused by environmental groups of seriously affecting the lives of the surrounding residents.

Not only does outdoor light source pollution exist, because most residents do not pay attention to the rational design of home lighting, light pollution in the home is also the most direct killer that endangers people's health.

Mr. Zhang, who lives in Tongzhou, Beijing, must get up before 6:20 every day. In the summer, when he is in the winter, he turns on the lights and sleeps, and his eyes will be hurt.

Several misunderstandings of home lighting

According to a survey conducted by the United States, about two-thirds of the world's people live in light pollution. Scientists have found that any artificial light source produces a subtle light stress. The long-term existence of this kind of light pressure can make people, especially infants and young children, behave uneasily and feel uneasy, making it difficult to sleep.

Wu Hao reminds consumers that we have the following common misunderstandings in lighting in our daily life. We should try our best to avoid the decoration, and strive to create a scientific lighting environment that is not only beautiful, comfortable and healthy.

The overall light source is too bright

In order to show the luxury, many people use a large number of brightly lit lamps, such as crystal lamps, spotlights, downlights, etc., and many people do not consider practicality. Simply install a full circle of spotlights on the ceiling of the living room. . Such lighting lacks scientificity, not only wastes resources, but also causes great irritation to the eyeball, which is likely to cause emotional irritability.

Brightness is not weak

In the home, the indoor space has different requirements depending on the use of different functions.

Generally speaking, the brightness of the living room, study room, restaurant and other spaces is stronger than that of the bedroom, the kitchen, etc., so that the design lighting is more in line with the law of human life.

The bedroom can be modeled after the lighting design of the hotel. At least three different types of lights are installed. One is the headlights, but the wattage is not too high, so that the lights are too glaring when the night is turned on. People like to read and read newspapers in bed. The brightness of the desk lamps can be adjusted. When reading, you can brighten up. You can dim when watching TV. You can also design a light night light with a light 30 cm from the ground. It can be kept at night for the night.

Bright and dark contrast is too strong

The indoor light should be as soft, uniform, and free of glare and shadows as possible. In order to create special effects in some spaces, some people use indoor lamps with opaque lampshades to make the interior clear and dark. When the person's line of sight turns from the bright area to the dark area, it takes a while for the eyes to see the dark areas. This is often easy to cause visual fatigue.

Colorful lights

In some families, when choosing lamps and light sources, in order to pursue romance and luxury, they often neglect reasonable lighting needs and design the lights into colorful ones. The color of the messy lights not only damages vision, but also interferes with central nervous system function.

Regardless of color temperature

Most people only consider illuminance when purchasing a light source, and rarely consider color temperature. Generally, in indoor lighting, the main light source is a cool color, and the auxiliary light source should be a warm color. In addition, from the use of the room, the study room, living room, kitchen, etc. should use a cool color light source, and the bedroom, bathroom, balcony, etc. should use a warm light source.

Fluorescent table lamp placed on the bedside

People always like to put a fluorescent lamp on the bedside table. They don't know that this kind of lamp looks warm, but it has the disadvantage of stroboscopic, and it may make a loud noise when used for a long time. Reading books and playing computer in such an environment can cause harm to the human body, such as decreased vision, dizziness, and insomnia.

Adjustable light source always adjusts brightness to maximum

Adjustable light sources are favored by many people because they can be brightened and dimmed at any time according to different needs. However, many families are used to maximizing the brightness for a long time, which will greatly shorten the service life of the light source. The brightness of the adjustable light source is preferably controlled at 60% - 80%, and the maximum brightness is preferably controlled at about 90%. Because from the naked eye, the brightness is adjusted to 90% and adjusted to 100%, there is almost no difference, but it can extend the life of the light source.

Turn on the side of the TV wall

Some families will install spotlights on the side of the TV wall, or turn on the lights on the side of the TV wall while watching TV. This will affect the audiovisual experience and is not conducive to eye health. Wall lights, table lamps or floor lamps should be designed on both sides of the seat. The brightness when watching TV is preferably 50% of normal brightness.

Buy a light bulb and look at the color temperature.

How to avoid "light pollution" in home improvement lamps and improve the indoor visual environment?

Wu Hao believes that on the one hand, it is necessary to pay attention to reasonable indoor lighting design, such as paying attention to the color coordination of lighting, avoiding glare, selecting colors that have less influence on the eyes, and avoiding direct light to the human eye; on the other hand, consumers should also upgrade Regarding the concept of lighting design, buy large brands, high-quality light source products, and design a healthy and pollution-free living environment.

Wu Hao reminded that when consumers buy light sources, they should not only consider the illuminance, which is the wattage we often say, but also learn to consider the color temperature.

The bulbs produced by regular manufacturers will be marked with color temperature on the package. The commonly used color temperature is 2700K, which is the most common incandescent lamp. It is characterized by warm light but not bright enough for local lighting such as bedroom bedside and wall lamp. 3000K, is a relatively natural color temperature, is warm light, the light is warm and bright, suitable for the overall lighting design at home; 4000K, is neutral white light, is a cool color, can make people mentally concentrated, suitable for office , learning and other places. If there is no color temperature mark on the package of the light source, it is an irregular product and must not be purchased.

Because there is a guardian light, the home is a warm haven. In the bustling city, no matter how busy you are, seeing the lamp that lights up for yourself in the window, you will have a pinning and relying on it. The lights are colorful, and they create different home effects while lighting themselves. In the decoration design, we must not only pay attention to the beauty of the decoration, but also give us a light for our health, just because we are opening The lamp, while lit up, is also concerned about the family.
