Study Notes
Architectural Lighting Design
- Standard lighting design aims for clear vision without discomfort.
- Architectural lighting enhances building design through natural, electric, or combined light.
- Architectural lighting relies on architecture, interior design, and electrical engineering.
- Architectural lighting design deals with interior and exterior lighting systems to meet human needs.
- Lighting adds emotional value to architecture, influencing how people experience it.
- Light highlights building features, textures, colors, and shapes.
Architectural Lighting Design: Key Concepts
- Aesthetics: Lighting design impacts visual impact on people entering a space. This is important in hospitality venues like restaurants and bars.
- Function: Lighting must serve its intended purpose, enabling safe navigation in buildings.
- Efficiency: Sustainable design should use energy-efficient lights.
Color Rendition of Light Sources
- Color quality (color rendition) measures how faithfully a light source reproduces colors.
- White light is a mixture of various visible wavelengths (400-700nm).
- Spectral power distribution (SPD) shows the relative amount of radiation at each wavelength. This defines a light source's color characteristics.
Importance of Color in Lighting
- Artificial lighting can change a space, improving performance or aesthetics in any environment, from public areas to private ones. Professionals consider color important.
- Similar to how colors affect psychology, lighting color can influence people's mood and physical response.
Defining Color Regarding Lighting Application
- Lumens, Watts, and Kelvins are key terms: Lumens measure light brightness, Watts measure energy consumption, and Kelvins are a measure of color temperature.
Color Mixing
- Additive mixing: different wavelengths combine within the eye (cones in the eye combine light).
- Subtractive mixing: colored filters reduce the wavelengths that pass through.
Primary, Secondary, and Complementary Colors
- Primary colors cannot be made from other colors.
- Secondary colors combine two primary colors.
- Complementary colors combine to create either black or white light.
Color Modification
- Different colored surfaces react to light in different ways.
Color Interaction
- Color wavelengths interact with surrounding colors based on contrasts or complements.
Color Rendering Index (CRI)
- CRI quantifies the accuracy of a light source in rendering object colors compared to natural light.
- Higher CRI values mean more accurate color reproduction.
Correlated Color Temperature (CCT)
- CCT measures the color output of a light source.
- Measured in Kelvins (K). Higher Kelvin values indicate cooler colors.
- Different CCTs create different visual experiences in a space.
Examples of Good Architectural Lighting Design
- Images illustrate various architectural lighting design approaches. Images show various lighting techniques used in contemporary architecture.
Importance of Good Color Rendition
- Accurate color representation is essential in visually demanding tasks.
- Good color rendition is needed in various industrial tasks and applications, such as in printing, manufacturing, design fields and more.
LED Technology and Lighting Science
- LED technology has changed how white light is produced and color is perceived in lighting systems.
- The spectrum of light from LEDs can be adjusted to produce white light or colored light.
Comparing Lumens vs. Watts
- Lumens measure brightness. Watts measure energy consumption.
- Efficiency comparisons of different light types (incandescent, halogen, CFLs, LEDs) are shown.
