With the aging of the population, the development of families with fewer children, and the difference in living habits between children and parents gradually becoming larger, more families may choose institutional pension in the future. In this paper, Suggestions on the design of light environment space suitable for the elderly health lighting are introduced from three aspects: living space, traffic space and activity space.

Studies have shown that dim light makes the circadian system sensitive to light and bright light makes it insensitive, suggesting that relatively dim light levels in daytime facilities may make older people more vulnerable to light exposure (circadian rhythms) at night. To reduce the damage degree of circadian rhythm, the design of light environment of living space can be referred to as follows:
1) Provide a high level of daylight and artificial lighting during the day to reduce the sensitivity of the elderly to light at night.
2) In the evening, within an hour or two before the customary bedtime, reduce the light level to a lower value, preferably by converting the spectrum to a warmer tone.
