Lighting design should not only meet the basic use and lighting functions, but also facilitate installation, maintenance and operation. At the same time, in order to meet your spiritual needs, you should also create a different atmosphere for home life. Light environment is our thoughts and feelings about light in a certain visual space. Good light environment gives people outstanding visual experience, which directly affects our physical and mental health. The following small series introduces the lighting design principle and lighting expression of exterior wall lighting project.

First, the principle of lighting design

1, aesthetic principle

Lighting design should be integrated with decoration, beautifying the environment and creating art. In order to better decorate and beautify the space and render different space atmospheres, it is very important to use decorative lights.

2. Practical principles

Lighting design should meet the basic functional requirements. According to different occasions, different spaces and different lighting objects, different lighting modes and LED lighting lamps should be selected, and appropriate illuminance and brightness should be ensured.

3. Safety principle

The main purpose of lighting design is safety, and the installation and application should follow strict lighting safety specifications.

4, the principle of economy

Lighting design is not based on brightness, but on the basis of meeting the basic use requirements and beautiful decoration, it pays attention to economy and environmental protection

Second, the expression of lighting

1, point light performance: point light refers to a light source with a small projection range and concentrated in one direction.

2. Banding performance: It means that the lighting source is designed and arranged into a long strip light source band.

3. Surface light performance: Surface light refers to the luminous surface formed by the building facade, indoor ceiling or ground.

4. Static lighting and mobile lighting: static lighting-the lamp is fixed, the illumination is static, and the non-flashing lamp is static lighting. Mobile lighting, a mobile lighting method with rich artistic expression, is a common means in stage lighting and urban neon advertising design.

5. Laser: Laser is a beam of light emitted by a laser. The medium for generating laser beam is crystal, glass, gas and fuel solution.

Lighting planning is to meet the needs of our visual physiology and aesthetic psychology, so that indoor and outdoor space can show the use value and appreciation value to a great extent, and achieve the same functional and aesthetic functions. Through the introduction of Bian Xiao, I believe everyone has a certain understanding of the external wall lighting project.
