Indoor and outdoor lighting are essential elements in the design of spaces and environments. Both types of lighting play an important role in improving the quality of life and creating different emotions in people. Proper use of both types of lighting can create beautiful and efficient spaces.
Indoor lighting: Refers to lighting inside buildings and can have a positive impact on people’s mood and efficiency. Indoor light sources include ceiling, wall and table lights.
Outdoor lighting: Refers to lighting outside spaces such as gardens and building facades and can increase the security and beauty of the environment. Outdoor light sources include park lights and projectors.
Difference between indoor and outdoor lighting
Indoor lighting:
It is used for indoor environments such as homes, offices and commercial spaces and indoor lighting of hospitals and offices.
Its main purpose is to provide appropriate light for daily activities and create a sense of peace and comfort.
Indoor light sources include ceiling, wall, table and hidden lamps.
Outdoor lighting:
It is used for outdoor spaces and open environments such as gardens, parks and building facades.
Its main purpose is to provide security, increase beauty and create attractive light effects in outdoor spaces.
Outdoor light sources include park lights, projectors and hidden lights in paths and plants.
Lighting Design Standards
Adhering to lighting design standards ensures that environments have optimal and appropriate lighting, which helps improve the quality of life and work, reduce energy consumption, and increase safety. Lighting design according to these standards can provide a pleasant and efficient experience for users of different spaces. Lighting design standards are developed to create appropriate and optimal lighting in different spaces. These standards include the following:
- International standards: Such as IEC standards (International Electrotechnical Commission) and ISO standards (International Organization for Standardization), which determine general criteria for lighting design.
- National and regional standards: Each country may have its own standards. For example, ANSI standards (American National Standards Institute) or CEN standards (European Committee for Standardization).
- Application-specific standards:
Indoor lighting: Includes standards for offices, homes, schools, and commercial spaces.
External lighting: Includes standards for streets, parks, public spaces, and building facades. - Ergonomic criteria: Includes lighting settings to prevent eye strain, increase comfort, and improve people’s concentration in work environments.
- Safety criteria: Includes standards to prevent sudden accidents such as electric shock or fire.
- Environment and energy consumption: Includes standards to reduce energy consumption and increase efficiency, such as using LED lamps and intelligent control systems.
- Appearance and aesthetics criteria: Includes lighting design principles that contribute to the beauty and attractiveness of the environment, such as using hidden lights and accent lighting
Steps for Interior and Exterior Lighting Design
