When designing a space, lighting first needs to solve the problem of space lighting, and then its specific use. For example, if you're designing an office, the lighting design for the office space should promote productivity for office workers. Because the lighting here needs to help employees adjust their mood during the day, the light intensity should be adjusted manually if possible.

In home lighting design, different rooms have different lights. For example, the kitchen needs brighter lights with high color accuracy, while the living room lights should be warm and soft. The entrance to the house should present a welcoming feeling, but also a transition from outdoor sunlight to indoor light.

At night, the lighting of a home is also a turning point from the dark space outside to the warm environment inside, but this transition should not go beyond the human senses, and it also needs to help the user relax. Before going to bed, the lighting intensity should be reduced to make the user relaxed, and a certain brightness should be ensured at the same time.

Numerous studies have shown that incorporating natural light into daily life has many benefits. There are relevant information that natural light can provide substances that are beneficial to the human body, which can not only effectively regulate the human biological clock, but also have great benefits for health. Natural lighting has the same effect on home lighting design systems, which not only means energy saving, but also allows users to have more contact with nature, regulate mood, and help sleep. Living in a place with strong natural light can improve the user's biological clock and mood. Watching more electronic products at night will have the opposite effect.

Good lighting design can not only improve the mood of users, but also have a certain impact on the shape and scale of the space. For example, if a small study has a light-colored wall, it can reflect part of the light through the wall, which will make the space look larger. Recessed lighting can make the space softer and look bigger.

LED lighting comes in different brightness and colors, so designers prefer this lighting method. Advances in LED technology have led to the application of new devices, such as LED sunroofs. These installations can simulate the viewing angle of windows, and the "skylights" emit light similar to natural light, and can also open up ventilation while bringing a positive atmosphere to the space.
