Buy lighting learn to see the color temperature

Lights can be seen everywhere in life. While most people enjoy the light it brings, they ignore the potential health hazards it may lay. From the dazzling neon outside, to the use of unreasonable lighting fixtures in the home, ubiquitous light pollution is like a beautiful invisible killer that threatens our health.

Most families will not choose lamps

At 11:30 in the evening, Ms. Song of Fengtai District of Beijing was unable to sleep. The dazzling red neon flared out of the window and flashed into the bedroom through the slits of the curtains. This made her particularly annoyed. Everyone is also exposed to the threat of indoor light pollution every day. Mr. Zhang of Tongzhou, Beijing, gets up at 6:30 every day. It's okay in the summer, and it's late in the winter. Every time he blinks and turns on the lights, his eyes are stung.

Senior Wu Yi, senior expert designer of Dongyi Risheng Original International Villa Design Center, told reporters that in his years of work in the home improvement industry, almost 90% of households only pay attention to the appearance, energy saving, and power of lamps when selecting lamps. As for how the illuminance of the luminaires, the size of the color temperature, etc. are related to whether the lighting environment can meet health standards, few people care. In a home store, the reporter randomly interviewed 20 consumers. They all said that when selecting lamps, they mainly consider the appearance of beauty, do not understand what color temperature is, and they know little about lighting design.

Home lighting eight errors

According to a survey conducted by the United States, about two-thirds of the world’s people live in light pollution. Scientific research has found that any artificial light source produces a subtle light pressure. The existence of such light pressure for a long time will cause people, especially infants and young children, to show restlessness and restlessness, resulting in insomnia. Wu Hao reminded consumers that the following common mistakes should be avoided in daily life in order to create a scientific lighting environment that is beautiful, comfortable and healthy.

The overall light source is too bright. Many people use luxurious lighting fixtures such as crystal lamps, spotlights, and downlights in order to show luxury. Some even install a full circle of spotlights on the ceiling of the living room. Such a lack of scientific lighting, not only a waste of resources, but also cause great irritation to the eye, easily lead to emotional irritability.

There is no difference in brightness. Different spatial functions in the home are different, and the requirements for contrast are not the same. In general, the brightness of the living room, study, restaurant and other space than the bedroom, kitchen and other space more strong, this is more in line with the laws of the human body and rest. The bedroom is best to install at least three different types of lights, one is a headlight, the wattage is not too high, so as not to be too dazzling at night when the lights are on; one is a table lamp, many people like to lie in bed reading newspapers, reading lamps The brightness of the best can be adjusted, brighten up when reading books, dim when watching TV; you can also design a soft light night light 30 cm away from the ground, open at night, easy to get up late.

The contrast is too strong. The indoor lighting should be as soft, uniform, glare-free, and shaded as possible. Some people create special effects in certain spaces. The use of lamps with opaque lamp shades indoors leads to bright and dark interiors. When people's eyes move from bright areas to dark areas, the eyes have to adapt for some time to see objects. Recombination easily causes visual fatigue.

Colorful lights. When some families choose lamps and lanterns, they are pursuing luxury, often neglecting reasonable lighting requirements, and designing the lighting to be colorful. The messy light color not only damages eyesight but also interferes with the function of the brain's central nervous system.

Does not consider the color temperature. Most people only consider the illumination when purchasing a light source, and rarely consider the color temperature. In indoor lighting, the main light source should be cool and the auxiliary light source should be warm. In addition, from the use of the room, the study room, living room, kitchen, etc. should use cold light source, bedroom, bathroom, balcony, etc. should use warm light source.

A fluorescent lamp is placed on the bedside. People always like to place a fluorescent lamp on the bedside table. They don't know that this kind of lamp seems to be warm, but it has the disadvantage of stroboscopic flash, and when it is used for a long time, it will also give out a kind of “pop” sound. Reading books and playing computers in such an environment can cause harm to the human body, such as decreased vision, dizziness, and insomnia.

Always adjust the brightness of the adjustable light source to maximum. Due to the need to adjust the brightness and dimming, the adjustable light source is favored by many people. Many families are accustomed to maximizing brightness, which not only shortens the lifespan of the light source, but also adversely affects human health. Adjustable light source brightness is best controlled at 60% - 80%, the maximum brightness does not exceed 90%.

Turn on the lights on the side of the TV wall. Some families will install spotlights on the side of the TV wall. When watching TV, they only turn on the lights on the side of the TV wall. This will affect the audiovisual experience and it will also adversely affect the health of the eyes. Wall lights, table lamps, or floor lamps should be designed on both sides of the seat. The brightness when watching TV is best adjusted to 50%.

Buy a light bulb to learn to see the color temperature

How to avoid "light pollution" in home lighting and improve the indoor visual environment? Wu Hao believes that on the one hand, we must pay attention to reasonable indoor lighting design, such as paying attention to the color coordination of lights, avoiding glare, choosing colors that have little effect on the eyes, and avoiding light. Directly to the human eye, etc.; on the other hand, consumers must also enhance the concept of lighting design, buy large brands, high-quality lighting, and decorate a healthy and pollution-free living environment. Wu Hao reminded consumers that they should not only consider the illuminance, that is, the wattage that we often say, but also learn to consider the color temperature. Regular manufacturers of light bulbs will be marked on the packaging color temperature, commonly used color temperature is 2700k, the color temperature of ordinary incandescent lamps, which is characterized by feeling warm light, but not bright enough, suitable for bedroom headboards, wall lamps and other local lighting; 3000k is The color temperature closest to natural light is warm, and the light is warm and bright. It is suitable for the overall lighting design in homes. The 3400k is a white light and is a cool light that allows people to concentrate and is suitable for office, study and other places. If there is no color temperature mark on the packaging of the light source, it may be an informal product and try not to purchase it.
