Notas do Editor
- Talk about the relationship between urban form and light. My goals are to present some thoughts on the future of urban lighting as it relates the potential for highly programmable and dynamic light sources. This is very informal so please feel free to ask questions, interrupt etc. Also I’m hoping to get some of your feedback on challenges that you’re facing when it comes to dreaming up new products and application ideas.
- The course was very successful. Student engagement was strong and they produced high-quality innovative projects. We also had the active participation of representatives from the planning, urban design, and public art departments of the City of Cambridge, as well as a local real estate developer, all of whom were excited by the projects and the possibility of future nighttime interventions.
- It was then time for one of the most spectacular public events Boston had ever seen – an outdoor performance of “The Masque of Power” with more than 1,000 students and faculty participating. Steam engines blasted out mists that in turn were illuminated by hidden colored high-powered lights lights – all designed by the same firm that created the much-admired night lighting of the Pan-Pacific Exposition in San Francisco in 1915. p. 90-91As a final good-bye to the old building, one of the searchlights raised its beam into the air until it crossed in the sky with the searchlight on top of Old Rogers. Then slowly the two lights died out, leaving everything in blackness, except for a single shaft of light rising skyward from the new courtyard. p. 91
- T10 = 1.25” diameterT8 is what we’re using in the end…

- In the 19th century engineers began specifying public lighting in great deal. 5.3: Lamps with and without light-deflecting globes. Shown above are the patterns of light thrown by each lamp. Shown below is the related light intensity measured in foot-candles. On the left the luminance is substantially deflected down on the street, on the right it is not. ….the above diagram shows the patterns of light thrown by each lamp. Light intensity is in foot-candles. Light A deflects more light onto the street. 5.8 (p. 105) Recommended lighting for residential street. Hierarchically ordered. 2,500-10,000 lumens at various heights…1929. Engineering perspective / priority. Quantification Automobile and driver’s needs shaped direction/development.Focused on asking “how much light” should there be?”, rather than “what should the quality of light should there be”?”
- The result of this engineering specification was a hierarchical organization of the city which works well…..however…..what happens when you can rearrange, reprogram and respond to the changing nature of urban life? Infrastructures of imageability….Lighting zones by category of street in a hypothetical city. (1930), Ward Harrison, O.F. Maas, Kirk M. Reid, NY: McGraw-Hill, 122. Diagram shows how city streets were characterized by their importance. Busiest and downtown were the brightest…How lighting engineers organized city streets hierarchically, busiest thoroughfares and downtown areas lit at highest intensities. (Jakle 2001, p. 104)
- Illuminating Engineering Society of North America, http://www.ies.org/ provides “Illuminance Recommendations” organized by visual tasks (orientation and simple, common, special) and seven categories (A public spaces, B simple orientation for short visits, C working spaces, D and so on…)primary focus is still to achieve the best light levels on the surfaces which are supposed to be illuminated, even if the calculations are more complexMost measurement instruments utilize either photodiodes, charge-coupled devices (CCDs) or photomultiplier tubes (PMTs)determining appropriate levels of lighting mixed vehicular and pedestrian areas defined in terms of horizontal illuminance and uniformitydifferent heights for roadway lighting (8-10 m) and pedestrian areas (5-6 m)uniformity: ratio of the minimum illuminance value divided by the average value, e.g. 0.8 for the working area in an office (ibid., p. 93), otherwise called the light distribution on task planeRobert Bean. (2004) Lighting: Interior and Exterior. Oxford, Burlington, MA: Architectural Press, Part 3: Chapter 24, p. 275-280.Or from the thesis in New York IT:Lighting of roadways, sidewalks, avoiding objects and wayfindingSafety of users security against crime and theftHorizontal illuminance: “density of luminous flux falling onto a horizontal surface, measured in lux (lumens per square meter) or footcandles (lumens per square foot), measured 0.91m or 36 inches above the ground at grade outdoorsVertical illuminance: Same thing only on vertical surfaces
