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.
