With the improvement of people's living standards, the indoor space environment no longer uses only one lamp to meet people's basic needs for lighting, but uses the artistic style and indoor environment of lighting design to create a suitable visual light environment.

Reasonable lighting design not only meets people's basic needs for brightness, but also creates different environmental atmospheres according to different space scenes, which should meet people's psychological and physiological needs.

Lighting design is closely related to human health, as evidenced by photobiology studies in recent years. Under the right irradiation conditions, whether ultraviolet, visible or infrared, it can have a positive physiological effect on the human body. However, in the case of insufficient or excessive exposure, the effects of light radiation are negligible and potentially hazardous. For example, ultraviolet rays can cause cataracts, retinal mutations, etc. Blue light can cause irreparable damage to eye cells.

The effect of lighting design on the rhythm of the body: the hormone produced in the human body is melatonin, a sleep hormone, and in a dark environment, the secretion of melatonin will increase; Conversely, under white high-light light, secretion is controlled. People regulate their body rhythms by increasing or decreasing the secretion of melatonin. Melatonin secretion increases when we sleep. That is to say, even at night, if you stay in a space with high illumination of white light, the sleep hormone melatonin cannot be secreted normally, and people cannot get normal sleep.

Lighting design Effect of lighting: Under higher light, people's wakefulness is significantly improved, so there are better working conditions. When the light is low, the sweetness and bitterness of the person will become flat. Therefore, when studying, working, and cooking, giving higher light helps to better complete the task.

Influence of color temperature in lighting design: High color temperature light can control melatonin secretion, improve cognitive task operation level and mood. Low color temperature lighting relaxes easily, helps digest food, and increases saliva production. So meals should be carried out under warm lighting.

The warm light source turns blue, purple, green and other colors gray and loses their original appearance. Cool light sources (white light) make warm colors (red, orange, etc.). Dark, while cool (blue, green, etc.) will be brighter and more vivid. What color clothes to wear for what occasion? Use a light with adjustable color in front of the mirror, and professional lighting design can adjust the color of light according to different occasions.
