Glare is a visual condition on the field of vision that can cause discomfort and reduce visibility due to an improper distribution of lighting intensity or extreme contrast of lighting intensity in space or time.
Glare causes a sense of brightness in the field of vision that the human eye cannot adapt to, which can lead to disgust, discomfort, and even loss of visual acuity.
The generation of glare has a direct relationship with the optical design, installation height, arrangement, and use environment of lamps.
Types of glare
Lighting Glare is classified as a big reason for causing poor illuminating quality in the lighting industry, and it needs to be addressed further. Research shows that about 70 percent of people have an aversion to glare in daily work, life, and sports.
So, how many types can lighting glare can be divided into? What on earth is the harm of lighting glare?
Adaptive glare
Adaptive glare refers to the vision loss that occurs when a person moves from a dark place to a bright place, and the lost vision can be restored after a short period of adaptive time.
Adaptive glare is less harmful in many places because the recovery time for vision is very short. However, if it occurs during driving, for instance, at the tunnel exit, it is necessary to choose suitable LED tunnel lighting to reduce the unsafe effects of this glare.
Inadaptable glare
Inadaptable glare refers to the vision discomfort caused by inappropriate lighting intensity distribution and a high-brightness light source existing within the visual range.
When confronted with this type of glare, people tend to avoid visual damage subconsciously by the method of visual escape. Prolonged exposure to this type of glare can lead to visual fatigue, sore eyes, watery eyes, and impaired vision. Inadaptable glare is common in life.
Disabling glare
Disabling glare refers to reduced visual function or temporary blindness caused by glare from a light source. Disabling glare is easy to understand and common.
It is believed that many of us have experienced the experience of looking at the sun for a long time or being dazzled by the high beam of a car, resulting in a black eye.
What are the harms of lighting glare?
- Glare makes you have to squint your eyes when playing on a sports field, which seriously affects the movement experience.
- Strong glare of the workplace in a factory will make the workers work less efficiently, easily fatigue, and even make mistakes at work.
- Strong glare in supermarkets will seriously affect consumers' shopping experience, weaken the attractiveness of goods, and reduce their consumption desire. Consumers' overall impression of the whole supermarket is greatly reduced.
- The glare problem of street lamps is often complained about by residents. They claimed that it would affect their health, cause insomnia, disrupt circadian rhythms, and not be good for children, animals, or anyone.
Low-Glare Lighting Contribute to Better Visibility and Comfort
Where there is light, there is glare, either high or low. Intense glare will seriously affect lighting quality. In order to improve people's satisfaction with the lighting effect, reasonable restrictions and anti-glare measures must be taken. Low-glare lighting fixtures can solve this problem at the source.
To understand low-glare lamps, we can start from the benefits of low-glare luminaires in various application scenes.
Boost Factory Productivity
A pleasant working environment is more likely to produce high-quality products.
Installing low-glare LED high bay lights in a factory can reduce workers' anxiety and make workers more focused on their work, reducing the rate of work errors. This can result in big savings when compared to high-glare lamps and low CCT traditional industrial lighting products, and a higher return on investment.
Deliver Clear Visibility for Athletes and Fans
The anti-glare LED sports light, at the beginning of design, will be properly handled in the design and will give enough consideration to backlight control, upward-light control, and glare control. So when the sports lights meet the requirements are used on the high mast of the stadium.
It will deliver an even and excellent lighting spread and bring athletes, spectators, and judges an extraordinary visual feast of sports events.
Safer Streets with Low-Glare Illumination
Some agencies seem to be aware of the glare problem caused by street lights and have developed a set of standards to regulate and solve this problem. The key technology to solve the problem of street light glare is to design different light distributions for them so that the street lamps only light up the area that should be illuminated.
The people's complaints about street light glare have faded away since the problem has been resolved as a result.
Enhance the Shopping Experience and Drive Sales
Consumers have their own ideas when it comes to choosing which supermarket to shop at. For them, the shopping experience is important. Supermarket lamps with low glare and high CRI are a way to attract customers to the store by creating an atmosphere of light.
Therefore, installing such lights in supermarkets will help attract customers, improve customers' shopping experience, and create more profits for supermarkets.
Improve Tunnel Safety
Reasonable lighting design can effectively reduce tunnel accidents and improve drivers' driving safety. As far as the safety hazards at the tunnel exit are concerned, the ingenious design of tunnel lighting is an effective way to solve this problem.
Proper tunnel lighting with a dimming function can gently change the lighting level from the tunnel entrance area, intermediate area, to the tunnel exit area without giving the driver the sense of obvious light change, at the same time, solving the glare problem from the low-light area to the high-light area.
