Natural light is the best light, we have to consider not only the practicality and beauty in lighting design, but also to consider the impact on health, improper lamps and lighting methods should be avoided, so how to create a high-quality healthy light environment?
Modern people spend 90% of their time indoors. The indoor environment has a great influence on people’s health. Light is the most direct impact on the eyes, glare, strobe and blue light will have certain damage to the eyes, also the entire light environment tone also affects people’s mood – warm light makes people more comfortable and relaxed, meanwhile cold light makes people more nervous and alert.
Tips 1. Glare
Glare is a kind of visual condition that causes discomfort and reduces object visibility because of unsuitable luminance distribution or extreme luminance contrast in space or time. In short, uncomfortable light that makes you feel harsh can be called glare.
The harm of glare – it will weaken visual function and affect work efficiency. Working in this kind of environment for a long time will reduce the absorption of calcium in the human body, and will cause psychological discomfort and visual fatigue, which will lead to irritability, inattention, headache, and eye diseases.
Glare in the home area can cause discomfort
Glare in the office area can cause fatigue and reduce work efficiency
How to solve the problem of glare – to control the light emitted from the luminaries within the cutoff angle of > 30 °, to minimize the effect of glare we can improve as below – 1. The position of installing luminaries, try not to let them come out and look directly into the eye. 2. Add anti-glare devices, such as our MIBON downlight series TD80512 with a very good anti-glare design.
Tips 2. Strobe
Strobe refers to the fluctuation of the luminous flux of the light source with a certain frequency. For the strobe above 80Hz, the human eye is not easy to detect, but it has a greater impact on the human eye’s spatial perception, like considering a moving object as a series of still images. Due to the stroboscopic effect, people may have the illusion that some fast-moving devices are running slowly or even stationary.
From a professional point of view, No stroboscopic should be “Imperceptible stroboscopic”, the Chinese industry standard for qualified LED stroboscopic requirements is 3125HZ.
Stroboscopic damage – may cause brain cell damage and migraine, may affect vision and work efficiency.
Tips 3. Blue light
Not all blue light is harmful, just in the range of 400 to 440, which increases the amount of toxin in the macula area of the eye and threatens the health of the bottom of the eye. Between 480 and 500 nanometers of blue light has a role in regulating biological rhythms, which are related to sleep, mood, memory and so on, and are actually beneficial to the human body.
In daily life, with long-term use of computers, mobile phones, and television, the eyes will feel fatigued and dry, except for daily eye care work, we can also wear anti-blue light glasses and other measures to reduce the damage of blue light.
