The unit introduces students to the basic element of Solid State Lighting technology, including it's role in energy consumption and in global climate change as well as possibilities in reduction of energy consumption. Topics include structure and working principle of Light Emitting Diode (LED), basics of optics and light-material interaction for lighting, lighting technology, radiometric and photometric measurements and units, effect of light in the built environment and for human well being, basics of color and human vision, measures for quality of light and lighting standards.

Laboratories cover light measurement, use of color standards and standard light sources, light spectrum measurements and defining the Color Rendering Index.


At the completion of the unit, students will be able to:

  1. Describe the basic physical phenomena to produce light
  2. Analyse how human vision system sees light
  3. Devise an intelligently controlled LED light system
  4. Design the predefined light spectrum by using different SSL techniques
  5. Create a model and construct a lighting system for specific needs
  6. Explain and evaluate the energy consumption of different lightings and formulate their relation to the climate change
