Types of LEDs — More than You Think

July 9th, 2012 by  

While the intro on LEDs in this post, and maybe more, may be a bit basic for some of our readers, I found this pitched guest post quite interesting and I learned quite a bit about LEDs from it, so thought it would make for a good CleanTechnica share — check it out:

Today, most people think of LEDs as those little dome-shaped lighting devices that put out just enough light to back-light a watch. While you would have been correct 10 years ago, LEDs have come incredibly far in the past decade. Not only that, but today’s LEDs are no longer sold only as individual little diodes used as an indicator light on your lawnmower, but as energy-efficient, long-lasting general replacement bulbs for many common incandescent light sources. Today, people are using LEDs for everything from lighting calculator screens, to lighting basketball arenas. Here are a few new types of LED items that you might not be aware of, and even the casual environmentalist would love.

LED Strips:

These innovative light strips consist of high-powered LEDs mounted on a super-thin flexible circuit board with an adhesive coating on the back. People use these LED strips for everything from accent lighting for their vehicles, to under cabinet lighting in their kitchen, and even for general lighting for rooms!

LED Bulbs:

Gone are the days where you have to be an electrician and possess a working knowledge of ohms and resistors to use LEDs. Today, using LED technology is as simple as screwing in a light bulb. With a wide assortment of common lighting, including MR16s, PAR type flood/spot bulbs, and standard 60W-equivalent LED bulbs (which achieve an incandescent 60W bulb’s brightness while only consuming 9W of power) available today, these easy-to-use and easy-to-install LED bulbs are powering the wider adoption of LED technology.

Automotive LED Bulbs:

That’s right, even your vehicle now can benefit from long-lasting, durable LED technology. LEDs turn on faster, have more color, and last way longer than standard automotive bulbs. Like standard household replacements, these Car LED lights generally just fit into the pre-existing socket.

Although these are the main categories consumers are adopting the fastest, there are other areas as well, including landscaping lighting, general accent lighting, and marine and RV lighting. There is good reason to adopt these technologies. According to the U.S Department of Energy: “Widespread use of LED lighting has the greatest potential impact on energy savings in the United States. By 2027, widespread use of LEDs could save about 348 TWh (compared to no LED use) of electricity: This is the equivalent annual electrical output of 44 large electric power plants (1000 megawatts each), and a total savings of more than $30 billion at today’s electricity prices.” As you can see, there is good reason people across the country are quickly taking to LEDs as their go-to light source.

    can i know the name of the author of this site pls? 🙂 it’s for research actually

  • alf564

    I looked at that today at Lowes and Home Depot…I have to wait until the holiday season for them…Thanks for the suggestion

    • Bob_Wallace

      Lots of them on line.

      Amazon has pages…

    The platform is 4X8 and the houses currently are using C7 bulbs.  I want to wire under the platform and not have to drill large holes to put the recept. thru the hole.  I was hoping LEDs would provide me with that option.  I used to use  DC lighting and that worked well but it is no longer available to me.  Any suggestions?  

    • Bob_Wallace

      Get a string of Christmas tree LEDs. Probably cost you less than $5.

  • alf564

    I have a train platform and am interested in using LED lighting for the buildings…how can I do this and at what cost?

    • Bob_Wallace

      You give almost no information and it’s not likely that any of us are lighting experts.

      If you’ve got only a few lights to replace that’s very different from a large scale project that’s going to need someone with expertise to design a system that works best.

      When you say “train platform” I can envision a tiny platform in a village for which one could just buy some LEDs and screw them in the existing incandescent fixtures to a “Gare du Nord”.

      If your project is more than a simple swap out I’d suggest you google around and find a few companies that specialize in lighting design and see what they have to offer.

    what about organic LEDs becoming the next gen displays?

  • Edward Kerr

    More efficient and safer than incandescent or compact fluorescent, what’s not to like? (the price for now but that will change in time)

    • just saw a new study (from NREL? or NRDC?) found LEDs are the cheapest option now. haven’t looked at it in detail yet.

      and the real challenge is getting people to go for long-term savings over lower prices at the register.

    I just had my bathroom fixed up, and used led strips with frosted glass in front to diffuse the ‘dots’.

    Personally I think it’s quite neat, and at circa 48w for 1300 or so lumens, fairly economical.
