Recently attended Microchip Masters and Cisco had a demo on network and lighting which gives a lot of flexibility to the end user

Iron

Not planning to do it in large scale but it is good to know all prospects and trends

Good presentation....very useful.

Systems engineer - making up session 5

@Alex - Thanks Alex.  See you in a couple of weeks.

Iron

@Carol - Thank you Carol.

Iron

@Carol - I don't think this next question has been asked or mentioned in the presentation, and at this late posting, I don't expect anyone will answer, but I'll ask anyway.  We already see LEDs in automotive tail lights, but when do you think they will be the primary source of lighting for headlights (and I don't mean those little decorative trim lights).

Iron

Concerning load shedding...  Here in Maryland our energy supplier, Baltimore Gas and Electric (BGE) has for the past couple of years implemented turning off our A/C.  The program is an opt-in, and there are choices of 50%, 75% and 100%.  It is offered at not only the industrial/commercial clients, but also the home market.  My household is a subscriber of this plan.  The A/C shutdowns occur on days of extreme temperatures, and the load shed by BGE is significant, and the program has been successful.

Iron

@Alex - Not presently doing anything w/LEDs, but a project doing the design/development would be nice.

Iron

@Alex - HW/SW/FW

Iron

Carol, thank you for a week of great lectures!

Iron

@Alex - not involved in lighting and buildings arena (beside my own)

Iron

@Alex - job function s/w, h/w and currently focus on standardization

Iron

Good to have access to recorded sessions...

Iron

Missed a class due to travel.

Iron

Thanks again carol

Alex stop interupting your presenters

Thanks

Interesting and Informative

Sums it up for me about the weeks classes

Mostly higher level code interfacing with firmwre in embedded applications

Maintaing older legacy software and also research and development of new software applications

Software Engineer II

Picking up the last class this week

Thank you for this week!

Iron

Interest in lighting at this point is in the area of smart home opportunities for unitilities.

Iron

Thanks, Carol, for making yourself accessible. I'm going to go check out your book (and the rest of your talks this week which I couldn't make it to).

Iron

I am interested in entertainment lighting uses for Film, Television and Concert Lighting.

Keep up the good work, and good day. Rod.

 

Iron

I hope you all enjoyed this as much as I have.  Thanks to Alex, EDN, and Digikey.

Have a great weekend.

Good points. And I'm not a betting woman. No one knows how the future will turn out. But don't lose heart. The industry is oving forward. Someday there will be the killler app for lighting controls. Or someday it will just seem backwards and out of date to not have lighting control. It is money down the drain. Money motivates, even if logic doesn't always. 

Blogger

reposting, 'cause I'm not sure what's happening (apologies if already posted):

Agreed in general wrt 6loPAN et al revolution precipice, but question: I'm interested in different markets, and obviously a not-insignificant market exists outside the realm of customers served by traditional building automation people--what I'm getting at is cost on, let's say, "RF system cost" for each "POL" (which could be an individual lamp or luminaire). Currently, COTS components are available in the budget of aforementioned building automation-scale people, but they're still not--ok, I'll be crude: X10 still exists and is in some sort of wide use (granted, in only 1 particular niche vertical, but my point is, if those such individuals can afford a 'house-wide' deployment, then we've removed acquisition cost from the list of issues for everyone else). Oh, question: any ideas, sense about anything happening to change that? (could be company, concept, massive tipping point trend; anything)

Iron

Carol.

Thanks for sharing your insight and knowledge about LEDs...

Iron

thanks again for the presentation.  Have a nice weekend.

Iron

hm...anyone else? (post streaming still working for everyone else?) stopped..

Iron

not seeing my post - test

Iron

Seems there are niche markets for certain custom LED designs. I wonder if there's a forum or onine gathering place for pooling demand to enable funding custom LED systems. Sort of like kickstarter.com, but demand sourced.

Blogger

Thanks for a week of great talks

Thank you Carol and everyone for this interesting week. You all have a great weekend.

Iron

BENEFIT: I didn't expect much from this module. But it was very informative. I now realize the effect of this fast growing electric load trend such as decreasing power factor. :o) LED as participants in the network of things is another point of awareness for me.

Iron

sdf

About LEDs pICKING UP RF NOISE,  EMAIL ME AND LET'S DISCUSS.

Blogger

@LevitonDave: actually, many business customers are on contracts that specify that they are interruptable.  These buninesses typically have back up generators anyway, so they are cut off (with warning, usually) when there is a potential overload situation. 

Blogger

@flaredOne

About noisy industrial environments, that's a really interesting niche. Email me and let's discuss.

Blogger

UTILITIES: One issue for them will be the increase in reactive energy. Edson light bulbs didn't have any to speak of. It may even pass that homes will be offered a break for the use of corrective power factor solutions.

Iron

Thanks Carol, it's been an interesting week and I know much more about LED lighting and control then I did on Monday morning. A great way to spend my lunch time.

Thanks to you and Alex. See all later.

Iron

Great insight to an important topic.

 

Iron

UTILITIES: I am referring to street lights applictions, but smart homes are likely to get a break for utilizing LED light fixtures. Some utilities are even giving some light bulbs to customers to promote their use.

Iron

What a lovely group of people here! Thanks for the nice feedback. Never gotten that at technical conferences.

Great conversations, too. We're all learning from each other.

Blogger

Utilities are worried about load for their generating capacity.  Load shedding is typically to avoid brownouts. usually there is a billing break if a business/building provides the utility the ability to turn off some portions of the load to avoid brownouts.

@Carol: btw, (OT and all, but) you might think of doing something like this: http://amzn.to/LenkLEDbook (also: bitly gives you metrics)

Iron

To answer a couple of the questions that were asked about wireless vs PLC, I think they are both useful technologies and I don't see either one going away anytime soon. They both have their uses. I think wireless is about to have a revolution based on 6loPAN driven technology improvement - open protocol, low power sensor, allows smaller IC, etc.

Blogger

Thanks Carol for the series of lectures. Enjoy Atlanta.

Thanks Alex, DN and Digikey.

Iron

Thank you, Carol.

 

Iron

I would think that DSM by utilities would be left to the industrial customer to control.  In other words, if the utility says you need to cut your usage by 20%, the business would decide what 20% on their own.  It would make no sense for the utility to have to understand the business enogh to pick what to control.

Blogger

Utilities are unlikely to get involved in lighting control. UNLESS they can package it as a paid service, particularly in a multi-building facility. But pursue that thought...

Platinum

great info Thanks

Iron

thnks Carol & Alex

Iron

thanks Carol , hope you ll be on the digikey again soon

Thank you Alex you too!

@flaredOne - got one e-version yesterday

Ok, since a couple of people asked, at the risk of being flamed, here's the link to the book.

@Carol: In a nut shell, will utilities get involved in wireless control of LED lighting, or because they own the poles, they are likely to use power iight communications and sensors to drive their policies?

Iron

@kim - insert RF inductors in the LED wiring (virtual o/c).

Iron

(we should see caffeine-cards just showing up in the next several weeks?)

Platinum

Thanks Carol! very enlighting serries, pun intended.

Iron

 

Thank you, Carol.

 

 

Iron

@Carol: you should post a link to your book right here!

Iron

Carol Thank you Carol for the courses this week, thanks Alex

Iron

Thanks Carol:for sharing your knowledge and experience

Iron

As always, the FIRST tool I-as-designer need is a datamining tool to quickly/efficiently search out and tabulate (create a full-fledged link page to) references/resources for design info. Second tool would be a "reputation"-based tabulator, helping define "who's out front" in design choices (no sense spending time evolving a system using an evolutionary deadend protocol...).

Thanks, Carol!

Platinum

Thanks for a great week - good overview and background.

Thank you for a week of informative presentation!

Iron

Thank you Carol, Alex and Digi-Key. Lots of great information

Iron

Thx. Carol and Alex

Iron

Thank you, Carol, what is the best way to contact you?

Iron

Great week of lectures Carol, thanks very much.

Iron

Thank you.

 

 

 

 

 

 

 

 

 

Iron

Thanks, Carol -- great series!

Iron

What are people doing for the matter of [reasonably accurate] ~POL power consumption metrology (&xmission etc etc)?

Iron

Good stuff, thanks Carol!

Iron

@Carol - question - what is the industry trend for communication, wireless or PLC for lighting control?

Iron

@flaredOne - True for retrofit - not for new construction.

I have an application for controlled lighting in an RF intense environment.  However, LED's de-modulate the RF signal and treat it as a DC bias and change the lighting level.  Any suggestions?

kw

Thanks for the info this week Carol!  Are there LonMark profiles for lighting control?  If so, how widely used are they?

Iron

EnOcean is a wireless Lighting and HVAC protocol out of Germany that has a large alliance behind it.

"brick-and-mortar" physical wiring is going to be counter-productive (hard to justify, ROI, etc) for MOST implementations, particularly upgrades.

Platinum

How about Echelon COS power line communications for light control, no IP overhead?

 

Iron

@Carol Have you installed smart lighting and/or LED lighting in your home?  How was your experience with it?  Is there anything you are waiting on for costs or protocols to mature?

@ RMRSS -  in my oppinion, there is no need of that, this is more "slow" process

Iron

Hi Carol, Alex and all.

I'm sorry for the tardiness.

Iron

What network protocol appears to be winning industry acceptance?

what do you really mean by SaaS in this context?

Blogger

Question: Do you see ZigBee or Zwave becoming dominant for installations?

Iron

Carol, since most building electrical things are powered over the powerline, I'd like to know what industry coverage PLC access has ?

Iron

Hi Carol,

How about fiber optics for distribution and control?

Iron

"mesh"-networking heating up? Adhoc networks (particularly with mobile elements (smartphones meandering between offices)) are going to be fussy.

Platinum

@Paul Scott

Be sure to click 'Today's Slide Deck' under Special Educational Materials above right to download the PowerPoint for today's session.

Iron

it's not really necessary to have a unique IP address for each light.  Out of the building, it is not really useful to have those lights addressable.  In fact, that could be a problem. 

Blogger

Hi Carol - There is another control protocol similar to DALI called Sector by Leviton that supports ballast based digital dimming.

And (if we're looking for logical placement points for adjunct equipment) sounds like thermostat enclosures will probably start including WiFi access points too...

Platinum

Is there any design and development tool for controlling integrated LED lighting system?

Iron

Add some infra red LEDs around the perimeter of the traffic lights.

 

Gold

same problem with LED tail lights, not hot enough to melt snow and ice. needs heater!

Iron

so thermostats are going to start encompassing optical sensors too?

Platinum

I'm listening on Firefox on a Mac. Yesterday I listened on Firfox onunder Redhat Linux. Firefox isn't the issue.

Sounds like a niche for a smart phone app to allow you-working-late to control local lighting.

Platinum

interested in building automation, monitoring and local control also.

Iron

It's working fine for me with Firefox

Iron

Many thanks for your fine coverage that was well balanced between breadth and depth.

Iron

I use Firefox 11 without any problems

Iron

industrial environments have a HUGE problem with localized RFI, data-swamping noise, associated with various processes (welding, etc). 4-20 mAmp circuits were an early solution...

Platinum

You should let people know that the broadcast is not supported under Firefox.  I just now got in via IE.

Gold

I think large scale adoption won't take place until electricity prices zoom up. NA electricity is too cheap! Comments?

Iron

the mention of "Big Data" seems gratutious.  This is not a hugh amount of data.

Blogger

 - TI has some excellent reference designs for LED based lighting, that includes both schematics and source code. Its freely downloadable (once you register at TI),,and you may be able to glean some ideas by studing what they did. The URL reference is http://www.ti.com/lsds/ti/microcontroller/32-bit_c2000/tools.page and look under the "Lighting" heading under Application kits.
