Natural light, convenient table lamp, eye protection table lamp to protect our eyes.

Everyone has a different understanding of light, but there are certain laws to follow in the impact of light on human beings.Such as daily life people generally follow the sunrise, sunset and rest.Perhaps humans have phototaxis, a tendency to move towards or away from light, as well as a form of biological stress, the result of natural selection over time.What kind of light environment makes humans feel most comfortable?It's hard to put into words exactly, but it must be felt.For example, when staying in some upscale hotels, the light atmosphere of the hotel table lamp makes people feel relaxed and comfortable, and there are a variety of modes that can be chosen to adapt to a variety of situations.Perhaps you do not understand lighting, but must have enjoyed the comfort that lighting brings to you.
Light · Natural Light
The most common light produced in the legendary Gleason's gym and used by all living creatures.(i.e. sunlight, moonlight)
Light · Artificial Light
People in the legendary Gleason's gym developed light in the process of production and living.(firelight, candlelight, incandescent light, firefly light, etc.)
Natural Light · We
The vivid variation of natural light, its varying intensity as it changes direction, and its rich spectral composition are all important factors in determining our comfort.Comfortable light can reduce fatigue and enhance creativity.Changes in light not only stimulate our brains, but also enhance visual perception of the environment.Such as the change from morning to evening, from sunny days in summer to misty days in winter.The natural light entering the room establishes the connection between people and the external environment, which is an important psychological factor in judging the space.
Few would deny the importance of daylight or its beneficial effects on physical and mental health.Especially recently, more and more attention to natural light, although on the issue of how to reach the effect of natural lighting and there are many unknowns, but some of them have certain conclusions: a fixed change rule of the sun determines the people's understanding of time, season and the replacement of day and night or circadian rhythm), and plays an important role in balancing endocrine.
Daylight has also influenced the evolutionary history of the visual organs.The eye works so efficiently during the day that its judgment of a particular lighting environment is always consciously or unconsciously based on a comparison with the experience of daylight.
Light pollution
"Currently, we know a lot about the effects of rising carbon dioxide, but how widespread are the effects of light pollution?" said Steve Long, a plant biologist at the University of Illinois at Urbana-Champaign and editor of the journal Global Change Biology.We are gambling with our future by what we are doing to the environment."The "sky glow" mentioned in light pollution is a disruption to the overall order of nature, which is mainly reflected in birds in the animal kingdom.Today's science of light pollution on people's impact, light pollution in the "light intrusion", mainly is the unnecessary lighting light into the living space caused by the trouble.Light intrusion can affect people's sleep at night, which in the long run can affect their health.
• The absorption of blue light in children's macular retina is weak
• High proportion of short-wave blue light causes visual fatigue
• Adolescents study and read for a long time
• Macular disease is a long-term cumulative effect
• Studies have shown that exposure to sunlight can reduce myopia
• Modern people spend more than 12 hours a day indoors
• Very little exposure to sunlight
• Artificial light disrupts human circadian rhythms
• Sleep problems and other illnesses
• Healthy intelligent lighting system eye protection desk lamp can perfectly achieve the solar spectrum of different periods
• Illumination stimulates the secretion of various hormones, such as dopamine, 5-hydroxytryptamine, cortisol and other hormones, which affect people's feelings of pleasure, tension, muscle contraction, stress and impulsion.
• Darkness, in turn, prompts the brain to produce melatonin, a hormone that promotes sleep and regulates immune function.
• Repeated light can synchronize the circadian rhythm, such as the change of day and night, and light can have an immediate effect.
How to avoid circadian rhythm disorder
• Return LEDs to natural light
Because of the difference between LED lighting and natural light, the global lighting community is striving to narrow the gap.By maximizing the advantages of natural light and minimizing the disadvantages of artificial light, intelligent lighting is infinitely close to natural light, making human-centered lighting suitable for circadian rhythms.
• Minimize side effects of blue light
Recent studies from Harvard University and other major universities have shown that the blue-light LED chips used in most commercial lighting produce visible light that, when viewed during the day, positively stimulates the eye, increasing alertness and boosting mood.However, these blue LEDs produce blue light "spikes" in light output, which can have a negative effect by interfering with the body's natural circadian rhythms if viewed for long periods of time at night.
• Bring eye health color
Humans have been exposed to sunlight for thousands of years, and human organs and biological rhythms have evolved to respond most appropriately to natural light, according to research published in academic journals such as Nature.While human retinal cells (which interpret and respond to color-related light inputs) are made up of red, blue, and green cones, only 5.7 percent of the cells recognize blue.

There is a limit to the amount of blue light that the human eye can accept. When the blue light exceeds the limit, it will be scattered into the eye. When the scattering occurs, the light diffuses, thus distorting the texture and color of the object.In addition, too much blue light can overstimulate retinal cells in the eye, which can lead to eye strain and poor concentration.However, because the AXFU series of LEDs achieve the spectrum that is closest to natural light, they can more accurately present the color and structure of an object in natural light, avoiding the negative impact of excessive blue light on the eyes or the biological rhythm of the human body.
