Home lighting selection LED lights precautions

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 is inseparable 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 too good, 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 emotions are also susceptible. Professor Randy Nelson of Ohio State University said at the American Neuroscience Annual Meeting on January 21 that excessive exposure to light during the night may cause depression. In addition, light pollution can cause dizziness, depression, physical weakness and other symptoms of neurasthenia.

Natural lighting combined with artificial lighting

Home lighting should combine natural lighting with artificial lighting and cannot rely entirely 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 more expensive in the initial stage, they can benefit in the future and meet the requirements of green environmental protection in the long run.

The lights should be coordinated

The lighting should not be too complicated, 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 source: 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.
