Home improvement lighting vigilance "light killer"

According to a number of international research results, light pollution can not only cause eye diseases, obesity, insomnia and other symptoms, but even worse, it can lead to depression. How to use lighting properly? Is the light bulb as bright as possible? Answer it now for you.

In home lighting, people always like to place a fluorescent lamp on the bedside table. They don't know that this kind of lamp looks warm, but it has the disadvantage of splash screen, and the use of it for a long time will produce 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.

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 contrast between lighting and lighting is too strong. The indoor lighting should be kept as soft, uniform, without blinding and shadows 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.

The brightness of the room is not different in the home. There are also different requirements for different indoor spaces due to different functions. The ancient geomancy school put forward the principle of darkness in the hall, meaning 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 rules 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.

Ignoring color temperature For laypeople, when selecting lights, they only focus on power and shape, 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, daylight is 100%, incandescent lamps are 100%, fluorescent lamps can reach 90%-95%, and energy-saving lamps are 70%-80%. Do not blindly pursue a high color temperature when selecting lamps, especially when choosing a home lamp. It is best to choose a color temperature below 4000K and a color rendering index higher than 80%.
