Older people and young people differ greatly in the choice of lamps. Older people are not developing like children, but they face aging. So in the choice of lighting, the elderly also need to be paid attention to and taken care of.
Audio-visual instability has always been a major pain point for the elderly.
With the age, the sensitivity of the human eye to light gradually decreases. Cataracts caused by protein degeneration, senile macular degeneration caused by the serious degeneration of visual cells and pigment epithelial cells, and a variety of eye diseases caused by the decline of eye regulation ability occur frequently in the elderly groups which brings a heavy burden on the visual function of the elderly.
Now, do you realize the particularity of the lighting design of the elderly room?
There are two special reasons for the elderly house：
- Due to the degeneration of corneal and macular function, the sensory standard of older people is 1.5 times that of young people. This means that the same environment makes it harder for the elderly to see the surroundings.
- As they age, the elders are more likely to feel lonely. And older people are more susceptible to the surroundings.
In order to be able to see objects, the elderly lighting design is more demanding than normal people.
So how should the lights be arranged in the elder's room?
1. Increase the illumination
The illumination demand of the elderly is much higher than the young people, generally 2-3 times that of the young people. Therefore, when the design of the elderly room, the illumination demand this factor needs to be paid special attention to.
As the sensitivity of pupils to light is getting weaker, the elderly demand for lighting brightness is far higher than that of other people. So many elderly apartments in the design design are higher than the general residential buildings. But the blind pursuit of illumination is not desirable and may even be self-defeating. Fundamentally, the cause of visual defects is not only and the impact of illumination varies from person to person.
2. Reduce the illumination contrast
The old man's sensitivity to light continues to decrease. Increased intraocular light scattering directly increases the imaging size of the light source in the retina. The larger this size range, the easier glare. So older people are more sensitive to glare than young people. This is why we must scientifically adjust the illumination of each space.
If the lighting strength of all indoor spaces is the same, it will bring great inconvenience to the daily life of the occupants. On the large basis of reasonable illumination, we need to further consider the light demand situation of the respective use area.
In general, the law of residential illumination requirements is as follows:
Living Room> Bedroom> Kitchen> Toilet> foyer, hallway and balcony.
In order to fit the visual characteristics of the elderly, the residence should avoid the use of the spotlight as far as possible. We would best to choose a relatively soft tube light or use the light film to weaken the light. Light across regions also requires a balanced transition to minimize the bias between illumination.
3. Select the appropriate color temperature
The elderly are more likely to feel lonely, so in the design of the elderly psychology, we should pay attention to the choice of color temperature!
If the elderly stay in a too cold environment for a long time, it will deepen their psychological loneliness. If the selected color temperature is too warm, it will make their eyes feel uncomfortable. Therefore, it is generally recommended to choose 4000k of color temperature which will be more neutral. And the environment under this color temperature will also be more bright and clear.
When using warm color light in a large area indoors, it can create a warm and peaceful environmental atmosphere and achieve the effect of relieving the mood of the elderly.
However, it should be noted that the impact of the color temperature of the light source on people is not absolute. It and the illumination are interrelated and work together on people.
4. Smart light band design
Elderly falls have become a great concern for their children. We need to consider how to reduce this from happening through some designs.
For example, place an intelligent induction light belt or ladder lamp around the bed. When the old man gets up at night, he does not need to find switches to see the road situation. This can effectively reduce the problem of elderly wrestling.
Because of the deterioration of his eyes, the old man became extremely sensitive to the problems of some lamps and lanterns. The most common problem is the problem of strobe and glare. Young people may not yet be able to understand this issue. But if the anti-glare of lamps is not good enough, it will not have a particularly big feeling for young people, but for the elderly is completely different. This is also why disability and discomfort glare are most visible visually affecting the elderly.
The lighting of the elder's room need be more functional.
