The architecture of light: architectural lighting design concepts and techniques. A textbook of procedures and practices for the architect, interior designer and lighting designer pdfdrive com

Some common manufacturers of small, localized lighting control systems include the following:
Watt stopper,
Lutron “Grafik Eye”, and Crestron.
These types of local lighting control systems can also be located far from the lighting loads that they control. In many commercial projects, a simple local lighting panel is used only for its built-in time-clock and all-on and all-off functions.
All of the devices discussed here are intended to add to the functionality of a lighting design and increasingly to tackle the two largest electricity wasters: Lighting inadvertently left on, and excessive lighting with no local control for reducing it. Without the consideration of these technologies, one is living in a world of light switches on the wall that must be manually turned on and manually turned off. A designer should consider how each lighting addition will be controlled and whether these control technologies will provide a benefit. It is highly advised that a designer employ the assistance of a lighting control manufacturers’ local representative, who can assist in specifying components for these systems.
The various levels of control capability are the crowning touch on the lighting design in a space. A careful consideration of cost, complexity, and convenience will dictate the appropriate lighting control system for each design.

Chapter 24 The Preliminary Lighting Layout “Redline”

“The preliminary lighting layout is where our design concepts start to become buildable.”
Now that we have been introduced to a vocabulary of luminaire types, applications, and control methods, we are ready to move forward in our design. The preliminary lighting layout is the intermediate step between lighting concepts and lighting drawings used for construction. It is an evolving layout of lighting luminaire locations that gives the designer the opportunity to ponder and select lighting equipment and fine-tune the locations, applications and control of these luminaires. This preliminary layout is often referred to as a “redline layout” because luminaire locations and notes are often marked in red pencil and undergo numerous changes and tweaks before the document is finalized. The redline layout is where our graphics, descriptions and calculations are translated into individual symbols that represent specific pieces of lighting equipment.
Creating the “Redline” preliminary layout is basically the process of “solving”
the conceptual light map that has been created. A clear, well-executed light map with notes and descriptions should pretty much solve itself, leaving the designer with the simple task of matching lighting equipment and locations to the already- documented lighting applications as indicated on the light map.
Figure 24.1 The process of marking ideas (here in red) for the placement of specific lighting equipment.
The two significant tasks that are accomplished through this “redline” layout are the locating and selecting of luminaires. These decisions will form the basis of the final construction documents - the Lighting Plan, Luminaire Schedule and Luminaire Cut Sheets - that will make our design buildable.
There are very few rules for the graphics and symbols used in laying out
preliminary lighting intent. The goal is simply to clarify the locations and types of luminaires to be used in the design. If symbols alone cannot successfully translate ideas, additional notes and comments can be used to provide more information. Luminaire mounting dimensions and mounting heights are also a useful addition.
