Indoor lighting design needs to meet four requirements, safety, functionality, artistry and economy. There are also certain skills when choosing lamps. The following is a detailed introduction to the lighting design and selection techniques:

  1. Human vision is very dependent on the brightness of the surrounding field of vision. When the brightness of the environment increases, human power and overall vision increase relatively, and the possibility of errors decreases.

  2. The soft lights distributed on different planes in the room can give the space a comfortable feeling. On the contrary, unsuitable or excessive lighting will cause visual damage and fatigue.

  3. Appropriate reflection control can protect eyesight. Although the reflection will not provoke vision, it may cause irritation and damage to vision.

  4. Good brightness contrast enables the eyes to distinguish between the real object and the background. In a lighting system, good brightness contrast will not cause strong reflected glare and provide people with a comfortable visual environment.

  5. The direction and position of the lamp projection is very important. At the same time, it also affects the distribution of light and shadows.

  6. Shadows can enhance the visual three-dimensional sense and provide guidance. The effective combination of scattered light and direct light can produce a good shadow state.

  7. The choice of suitable color temperature-in daylight, the color temperature of natural light sources will change. Therefore, artificial light sources can choose and adjust different color temperatures to create different lighting functions and situations.

  8, good color rendering index. The color rendering index is a measurement of the color reproduction ability of artificial light sources to express the natural color of an object. For interiors with a sense of design and rich furnishings, the color rendering ability of the light source is particularly important.

  9. Light energy affects people’s mood and feelings. The feeling of the interior and lighting is a subjective and unconscious impression. In recent years, the public has paid more and more attention to the importance of workplace lighting environment for work efficiency, mood and well-being.

  10. The basic requirement of modern lamps and lighting design is energy saving and environmental protection. Energy saving, environmental protection and health are the basic tenets of green lighting. In 1991, the green lighting advocated by the U.S. Environmental Protection Agency has been popularized all over the world, deeply rooted in the hearts of the people, and has a profound impact on lighting design. At present, there are many solutions for the installation of lamps and the reconstruction and reformation of the old low-efficiency system.
