Vision &lighting
•Light level•Control of Brightness Contrast and Glare•Contrast and diffusion•Economic Issues
considerations for good lighting
Daylight
•Admitting Daylight•The nature of daylight is determined by the architecture of the space.
•Controlling Daylight•Multiple Glazing•Orientation •Window Treatments
Artificial Light
Planning Lighting
•Determine the general aims in term of character and atmosphere•Consider the specific Purposes for which lighting is required•Ascertain the intensity level for the proper vision and balance against these energy and first installation costs and other factors to decide on lighting type.•Select fixtures based on general aims and specific needs•Place fixures
Lighting needs
•Task lighting•General lighting (ambient light)•Special lighting (accent light)
Lighting needs
•Levels of illumination (candle powe r, lume ns)•Brightness Contrast (reflectance)•Lighting for the aging population
Special Purpose Light
•Offices•Healthcare facilities•Restaurants•Retail stores and show rooms
Selection of lighting
•Incandescent light•Fluorescent light•High intensity discharge light \•Light-emitting diode (led) light •Fiber-optic light•Other light sources•Color characteristics of artificial lighting
Selection of lightingEconomic issues of Light Selection:
Cost of fixtures, installation, maintenance, repair, consumption, air conditioning ( to offset heat produced), saving in heat cost.
Comparison equation based on energy consumption: total wattage of lighting = Watts per square foot Floor area in square feet
Fixture Selection
Selection Depends on many factors: Type of light desired for a space Cost Look desired Maintenance Architectural or portable
Fixture Selection
Architectural & portable lighting
ARCHITECTURAL Lighting is fixed (recessed or concealed) into the structure of the building
PORTABLE LIGHTING includes movable lighting devices that are plugged into outlets
Fixture Selection
Types of light produced
CONCENTRATING or beaming, usually from a point source in one/many directions
DIFFUSING that scatters light in many directions
Fixture Selection
Types of light produced
The way fixtures direct their light output can be evaluated by LIGHT DISTRIBUTION (PHONOMETRICS) CHART. (fig)
Light fixtures designed as ‘bright spots’ create excessive brightness contrast that causes vision problems should be avoided.
Fixture Selection
Types of fixtures, Floor Table &Des k Lamps
Shaded incandescent LampsDesk lampsGlobe lampsReflector lampsUplights or Torcheres
Fixture Selection

Miscellaneous TypesClip-on Photo LightsLuxo lampsAntique reproductions
FIXTURE LOCATION & SPACING
Types of fixturesCalculating number & location - with architectural lighting use specific calculations to provide
illumination level of selected fixtures.
