Lighting is an important factor in any living environment. Proper lighting can greatly improve both the physical environment and the psychological environment of the living space. It is important to choose the right lighting fixtures to create a healthy and comfortable atmosphere. In order to create a comfortable atmosphere, it is important to select the correct light source, focusing on both the physical and psychological level. On the physical level, the choice of lighting affects brightness, temperature, and color. Natural light is always the best, as it provides a natural and comfortable environment. However, the balance between natural light and artificial lights must also be considered. If there is a lack of natural light, artificial lights can be used to supplement. The choice of light fixtures should also consider the psychological aspect of the living environment. For example, for living rooms and bedrooms, it is better to choose softer lighting that does not cause eye strain. Also, for task-oriented spaces, such as offices, brighter lights might be needed. In conclusion, the choice of lighting is an important aspect of designing an environment. Proper lighting can not only provide comfortable living space, but also provide a healthy and comfortable atmosphere. It is important to choose the right light source and light fixtures to achieve the desired effect.
