The first one: safe and moderate combination of natural lighting


Dr. Russell Reiter, an endocrinologist at the University of Texas Health Science Center in the United States, said that lighting is a drug. Abuse of light is a health hazard. Modern life can't be separated from all kinds of lighting, but if we use it improperly, we will have various problems and even adversely affect us. This is by no means an alarmist. There are still some problems in modern home lighting that need our attention.


Safety should pay attention to


Safety in family life should be placed first, which requires us to choose brand-safe, safety-certified products when purchasing lamps and accessories. Although the price of the products with safety guarantee is slightly higher, but the quality is passed, there is generally no problem. The author below lists some commonly used certification marks, of which China's compulsory product certification is mandatory, the most common.


Try to choose lamps that do not contain heavy metals


When selecting lamps, try to choose lamps that do not contain heavy metals, such as mercury, cadmium, lead, etc. These heavy metals are not easily degraded by microorganisms and have obvious toxicity, which has a great impact on the environment, especially the energy-saving lamps contain mercury vapor. Broken light bulbs can cause mercury vapor to escape, so be careful when choosing. At the end of the product specification, an indicator of heavy metals is generally given to tell the consumer which medium metals are present in the product.

Follow the principle of moderation


The home environment is the environment of our daily life, so the lighting should follow the principle of moderation, and the room should not be too bright or too dark. Too bright lighting is harmful to our eyes; too dark indoor environments are prone to visual fatigue, and our mood is also susceptible. Professor Randy Nelson of Ohio State University said at the American Neuroscience Annual Meeting on January 21 that excessive exposure to light at night may cause depression. In addition, light pollution can cause dizziness, depression, physical weakness and other symptoms similar to neurasthenia.


Natural lighting combined with artificial lighting


Home lighting should be combined with natural lighting and artificial lighting, not all of which rely on luminaire lighting. Sunlight can kill harmful microorganisms in the indoor air; it can improve the body's immunity. Experts believe that two hours of daily sunshine per day is the minimum need to maintain human health and development. Natural lighting is also indispensable, and home lighting should not block the sun outside.


The second item: focus on energy saving should not be too much


Choose energy-saving lamps


The average daily lighting time in home lighting is not long, but energy conservation is still an indicator that needs attention. Although the lamps with good energy-saving performance are larger in the initial stage, they can benefit in the future and meet the requirements of green environmental protection in the long run.


Lighting should be coordinated


The lighting should not be too much, so as not to endanger the health of the human body. If the color of the light is too large, it will be dazzling, not only will damage the vision, but also interfere with the function of the nerves in the brain. Too much color is prone to light pollution. An obvious example is the light pollution in the disco, which is easy to cause discomfort. In addition, unreasonable lighting colors can also affect a child's vision development. The color of the lights in a room should not exceed 3, and the colors should be coordinated.


Reasonable lighting with a good lighting environment


Finally, a brief introduction to the mainstream home lighting sources: energy-saving lamps, metal halide lamps, LED lamps. The life of energy-saving lamps can reach 10,000 hours, and the price is lower than that of LED lamps. However, energy-saving lamps contain mercury vapor, which may cause mercury pollution. It is not recommended to be used in large quantities in home lighting. Metal halide lamps are one type of incandescent lamps with a life span of 3,000 to 4,000 hours. Due to their relatively short life span and small illumination range, these lamps are generally used for indoor accent lighting. LED lights are also light-emitting diodes, which have many advantages such as long life, high luminous efficiency, energy-saving and environmentally-friendly lamps, and are superior to other lamps in performance. With the gradual decline in prices, LED lights will be the best choice for home lighting in the future.


In short, home lighting should combine scientific design with the application of new technologies. As long as these furniture lighting considerations are followed, efficient and environmentally friendly home lighting can illuminate our healthy and comfortable life.
