Learning about Lighting

 
Nicely laid out lighting learning project Discover Lighting, from the Illuminating Engineering Society (IES).

Discover Lighting includes an introduction into: A Brief History of Lighting, The Science of Light, Electric Light Sources, Lighting Applications and Sustainability topics.

As you Discover Lighting, you will also be introduced to the language of light. Throughout the course, lighting vocabulary is provided via roll-over links.

0. Introduction                                          1. History    

                  



2. Science                                             3. Sources

                  



    4. Applications                                       5. Sustainability

     



6. Are You Illuminated? (Lighting Test, after completing the chapters)

Once you have completed the course, you will have a chance to test your level of illumination. You must first, however, visit each chapter of Discover Lighting, and answer the short questions in the Fact or Fiction section of each page. Once you have attempted each Fact or Fiction question, you will be allowed to take the full test. If you pass, a certificate of completion will be mailed to the address you provided during registration.

I tested registration, is free OK, though only necessary anyway for those who want to do the questions and answers.


About the Illuminating Engineering Society, from their own information...

The Illuminating Engineering Society of North America (IES) is the recognized technical authority on illumination. For over 100 years; its objective has been to communicate information on all aspects of good lighting practice to its members, to the lighting community, and to consumers, through a variety of programs, publications, and services.

IES is a forum for the exchange of ideas and information, and a vehicle for its members' professional development and recognition. Through technical committees, with hundreds of qualified individuals from the lighting and user communities, IES correlates research, investigations, and discussions to guide lighting professionals and lay persons via consensus-based lighting recommendations.

The Society publishes nearly 100 varied technical publications, and works cooperatively with related organizations on a variety of programs and in the production of jointly published documents and standards.

Local IES Sections and many lighting corporations offer formal educational programs on lighting, utilizing material developed by IES. Sections offer programs related to specific applications based on IES standards - seminars on sports and recreational lighting, lighting industrial facilities, roadway lighting, museum lighting, to name a few. Virtually every curriculum devoted to lighting - from beginner to advanced - includes IES educational materials.

IES is almost 8,000 members strong. Its members work with lighting in a variety of capacities - lighting designers, architects, interior designers, government & utility personnel, engineers, contractors, manufacturers, distributors, researchers and educators - throughout the United States, Canada, Mexico - and around the world. They share a common interest in lighting, and a common desire to promote the use of the latest, most innovative lighting technologies, with a focus on judicious use of energy in all lighting applications.

New Book on Home Lighting

No, not a book lamenting the demise of the simple cheap bright broad spectrum Edison light bulb - rather the opposite, but hang on...



Book Review

Losing Edison
By James Bedell

Available via Amazon for Kindle reader around 11 dollars, other options click on image or the book title above.
Print-On-Demand version coming, says the author.

Since this book was written to show that phasing-out incandescents does not matter in making good lighting choices I was a bit sceptical, on getting a copy for review....

As the author introduces himself on his website
"It is my belief that all good lighting design must be sustainable lighting design."

But don't be deceived by the title,
it does therefore go way beyond that issue.

The author says it was his first attempt at any public writing longer than a blog post, but this certainly does not come across.
It is also well illustrated, both with useful functional drawings by the author, and photographs.

While on the content side I (and others) would argue that with incandescents one can make even better choices in some described situations, it is really a book about understanding lighting as a whole, and about how lighting designers reach their decisions.
As such it is of value not only to anyone making lighting choices, but also I would suggest to lighting designers themselves, in the breadth of the issues raised, which includes a very useful concluding part about how lighting designer work fits in with architects, interior designers, builders...


But to take first things first, in this book of three parts.

Part I,
usefully covers definitions such as lumens (which everyone will have to deal with rather than Watts), color temperature, color rendering index (CRI), and their roles.
It also covers Halogens, CFLs and LEDs in that respect, with good tips on what to look for in buying them, depending on the purpose they are for
- and with a good US Department of Energy Lighting Facts Label illustration.

EISA specifications follow, that is until 2014
(EISA specifications will also rule out the replacement Halogens in following years,
but fortunately for the sake of lighting advice, given also that the author is not overly fond of their still relatively high metered electricity use, Halogens are included in the book).

Then, different uses of different lighting and typical running costs based on defined electricity rates finish the first part.



In Part II,
the three basic concepts of residential lighting are covered,
ambient, accent, and task lighting,
with explanations of the principles involved in reaching relevant decisions of what
to use and how to use it.

Apart from the various types of lamp lighting and uses,
natural light and fire in various forms are included too, in a comprehensive overview.

Lighting control is not forgotten,
explaining the three major types of control systems:
local dimming/switching, single area controls, and whole-home systems.

As the author says, a common failure in lighting control is that the controls, whether a slide dimmer or a keypad, are misplaced in the room.
Ever on the sustainability note (which recurs with useful savings tips throughout),
a reminder how dimming makes lighting more sustainable.

Again,
for completion, outdoor Lighting is also covered:
Acknowledging that not everyone has such surroundings (or control of them),
entryways driveways and Walkways, patios and decks, trees/shrubbery are mentioned:
"Outdoor and landscape lighting is probably the least thought-out aspect of residential lighting for most homes."



The final Part III,
then takes a given lighting idea from concept to implementation.

Or, to put it as an edited extract:
"Having a lighting designer on board, let's figure out who else should
be on your team. I'm going to assume that all projects have an
electrical contractor and, in many cases, a general contractor.
Since we're talking about lighting design here, I've broken down potential
projects into three basic categories, which will serve as a rough
guide to who should be on your team:
1. Re-lighting a room. Here's a good opportunity to work with a
lighting designer; no other designers/collaborators are necessary.
2. Redecorating a room. If there are one or more spaces in your home
you'd like to redecorate, it's time to bring in an interior designer.
3. Total Renovation. If you are gutting one or multiple sections of
your home, you'll need the most complete team. Here's where bringing
in an architect."

Helpful advice on finding good architects, interior designers and lighting designers follows, along with choosing and working with project managers,
creating project budgets - and indeed sticking to them, and to any time limit that may apply.

Again, with practical and easily forgotten tips,
such as designing with an eye toward maintenance,
and guides to buying light fixtures as well as light bulbs.

The author also helpfully offers to give further advice to readers, in respect of his time.


To sum up then,
do not be misled (one way or the other) by the title of the book.
Edison is still included, of sorts, in describing the use of Halogen incandescent derivatives, and the book usefully covers home lighting in all its aspects.

(Look forward to that whiskey bottle now James ;-) )
