Illumination Systems: Light Quantities and Basic Definitions

• Light is electromagnetic radiation within a portion of the electromagnetic spectrum, perceived as visible light by the human eye
• Visible light has wavelengths between 380-780 nanometers (or 0.38-0.78 micrometers)
• Light is a radiant energy that propagates in the form of electromagnetic waves at the speed of approximately 3 x 10⁸ m/s.
• Includes different colors of light, with wavelengths and temperatures ranging from cool (violet) to warm (red).

Luminous Flux

• Luminous flux (Φ) is the measure of the total luminous energy emitted per second from a light source in all directions
• Unit of luminous flux is the lumen (lm)
• 1 watt equals 680 lumens

Luminous Intensity

• Luminous intensity (I) measures the light flux in a specific direction within a solid angle
• Unit of luminous intensity is the candela (cd).

Illumination (Illuminance)

• Illumination (E) measures the incident light falling on a surface per unit area
• Unit of illumination is lumens per square meter (lux) or lumens per square foot (footcandles)

Luminance or Brightness

• Luminance (L) measures the brightness perceived from a surface
• Unit of luminance is candela per square meter (cd/m²) or lambert.

Inverse Square Law of Illumination

• Illuminance (E) is inversely proportional to the square of the distance (r) from the light source
• E = I/r² (where I is luminous intensity)

Cosine Law of Incidence

• Intensity of illumination (EΘ) on a surface is proportional to the cosine of the angle (θ) between the light ray and the surface normal
• Eθ = E cos θ

Calculation of Illuminance at a Single Point

• Illuminance calculations at various points on surfaces, considering different angles and distances, are described in detail on the slides.

Calculation of Illuminance due to Multiple Point Sources

• The illumination at a point is the sum of all illumination contributions from multiple light sources.
