With the continuous development of urbanization, the behavior space of urban people is mainly indoor.Research shows that the lack of natural light is one of the important factors that lead to physical and mental diseases such as physiological rhythm disorder and emotional disorder; At the same time, unreasonable indoor light environment design is also difficult to meet and make up for people’s physiological needs for natural light stimulation.
Therefore, this paper aims to analyze how to give full play to the role of lighting in the design which is beneficial to human physical and mental health, and how to apply it in different residential spaces.
Ⅰ：Effecf lighton human health
①Visual function：
Sufficient light intensity level can make people see the target objects in different environments.
②Body rhythms：
The natural light of sunrise and sunset and indoor lighting affect the body’s biological clock, such as the cycle of sleep and awakening.
③Emotion regulation：
Light can also affect people’s emotion and psychology through its various characteristics, and play an emotional regulation role.
Ⅱ：Health lighting design recommendations
Considering the single requirement that people can complete certain activities with visual clarity in different spaces, it does not take into account the possible impact of lighting on human health. Therefore, in combination with the impact of various lighting elements on human health and lighting design standards in the aforementioned research, suitable lighting principles, lamp setting forms and selection principles will be proposed for different spaces in the residence.
Living room：Meet different functional requirements, and achieve the purpose of setting off the environment and atmosphere.
Recommended lamps：Basic lighting (chandelier or ceiling lamp) + key lighting (table lamp, floor lamp) + decorative lighting (embedded spotlight can be integrated into the ceiling).
dining room：Pay attention to the quality of light source to make the color of food more vivid.
Recommended lamps：Basic lighting (dimmable LED pendant lamp)
Kitchen：Appropriate illumination is adopted, and high illumination will make the taste sensitive.
Recommended lamps：Basic lighting + key lighting (LED strip lamp is under the cabinet).
Study room:High color temperature and high illumination, appropriate focus visual acuity in office space, and avoid glare.
Recommended lamps：Basic lighting (chandelier) + key lighting (LED table lamp) + decorative lighting (Spotlight).
Bedroom：Create a relaxing and comfortable environment, and choose circadian rhythm lamps to automatically simulate natural light changes.
Recommended lamps：Basic lighting (chandelier, ceiling lamp, downlight) + key lighting (wall lamp, floor lamp) + decorative lighting (lamp strip embedded at the head of the bed).
Children’s room：children’s eyes are developing, adjustable lamps should be selected.
Recommended lamps：Basic lighting (downlights, chandeliers or ceiling lights) + accent lighting (track chandeliers) + decorative lighting (track spotlights).
Ⅲ：Epilogue
With people’s pursuit of high-quality life, health lighting is playing a more and more important role. Designers should consider more comprehensive and humanized lighting design, so that people will not be affected by the surrounding light environment while enjoying life. How to make people’s body and mind in a healthy state through design is worth more discussion and reflection.
