invisible streetlight via LEDWaves LED lightingThere’s an awesome, awesome list up on one of my favorite sites, Ecofriend. In their words, “The rise in the demand for energy and the decline in its supply have made product manufacturers and designers come up with sustainable alternatives that help save energy or run on renewable sources of energy. The street lighting industry has also witnessed the change with many manufacturers unveiling next-gen solar-powered street lights and designers coming up with even better lighting solutions for the future. Boosting this green trend, here are 20 sustainable street lighting systems that can make streets green and safe.”

This is the kind of innovation that really appeals to me. All of the designs incorporate some combination of solar panels, wind turbines, LED lights, and other elements of sustainable energy. Here are the ones that especially caught my attention:

The Invisible Streetlight (upper right) by Johgoh Lee integrates double injection silicon, aluminum and a photo capacitor into a lovely organic leaf design, ideal for wooded roads. It is designed to be invisible during the day and to glow all night long. My main concern? It’s hard to tell from just the pictures, but they don’t seem to be secured in any clear way, so I’d worry about roving thugs stealing these fixtures. But maybe I’m just projecting my own desire to have one of these pretty lamps in my home.

Designed by  Haneum Lee, it composts organic waste that users throw into a wastebasket and then uses the methane which is released as a byproduct to fuel the lights. Unfortunately, this also strikes me as a “Only in a perfect world” kind of innovation. How many times have you seen random garbage tossed into an inappropriate recycling bin? Again, I kind of just want this for my house. This would save me a walk from the kitchen to the compost heap in my backyard on a nightly basis. (Though I suppose I do need the exercise.) And with energy-efficient LED lights, it wouldn’t require a whole lot of garbage to run itself. Also compost lamppost is just so much fun to say.

Its tree-like body is lined with nanotube solar cells and aqueducts leading from the water-filled base to seeds at the top. In addition to feeding plant life, the water conducts light from high-intensity LEDs stationed near the bottom. I have to say, the appearance of the tree kind of bothers me (it looks like EVE from Wall-E did it with a tree) but the dual functionality of sustainable LED street lighting and oxygen-providing plant life really wins the package for me.

There are a few more streetlights that I could go on about, but I highly recommend checking out the rest of the list for yourself. I’m not involved in civil engineering, but the possibility of seeing these eco-friendly designs on our streets in the near future is kind of putting me in my happy place.

Repost: An LED That Mimics Old Standby / American Consumers Apparently Don’t Follow Lighting News June 25, 2010

via the New York Times Green Blog:

In more sustainable design news, the New York Times Blog reports that Osram Sylvania has produced a new LED bulb (at right) that mimics the shape of a traditional Edison light bulb. The LEDs’ light emanates from the top, and they are supported by thick, arched heat sinks. It uses 12 Watts and is supposed to produce almost as much light as a standard 60-Watt lamp.


I have already mentioned that I prefer the modern look and functionality of an industrial LED light bulb (like the one at left), but I can see how one that can’t let go of old-fashioned lights could be “tricked” into buying this bulb. As someone who has worked with LED lights and knows a little bit about them, though, I can’t see how these heat sinks can be too effective. Usually they are composed of lots and lots of little ridges to increase surface area for heat dissipation; the chunky arches look like they minimize surface area. Anyway, I’m sure the heat sink on the Sylvania bulb works adequately, enough to be approved for sale. I’d probably just use oven mitts while replacing it.

The article goes on to make two more interesting points. First, it reveals another application for LED lighting: refrigerators used in retail. The lights in any refrigerator with a glass front are on 24/7, so there is a strong case for replacing the fluorescent tubes they typically use with more energy-efficient CFLs or, even better, LEDs. The lamps that you see in most refrigerators also generate considerable heat, with requires more work on the unit’s part because it needs to be cooled to maintain the proper temperature. This is where LEDs would again be extremely helpful, as they run a lot cooler than any other type of light bulb.

The most thought-provoking part of this article for me is related to the federal phase-out of inefficent lamps like incandescents. Though the lighting industry is working hard on developing marketable LED replacement bulbs, a survey of Sylvania customers revealed that 74% of them are unaware of the coming change. This is two years after Congress passed the bill for the phase-out. Rick Leaman, chief executive of Osram Sylvania, says he fears a backlash when consumers are unable to buy the old-fashioned bulbs they’re used to. He wants the government to start a campaign to raise awareness of the lighting revolution that the country is poised to see.

I guess I’m not surprised that three out of four Americans don’t know about the federal phase-out of the inefficient bulbs that are all around them. (Heck, according to the FCC, 80% of American broadband users [myself included] don’t know the speed of their own home broadband connections, which they also pay for and use.) I suppose I’m surprised that both the government and most light bulb manufacturers haven’t already taken the initiative to advertise the phase-out themselves.

When television was making the switch to digital, we saw tons of commercials warning viewers about it (albeit mostly paid for my digital cable companies), and the issue was also on the news a lot. It would make the US Department of Energy look good to show that they’re working on ways to help save the environment while maintaining quality of life for us. So I believe it’s on both the government and lamp sellers to publicize the phase-out which will effect the entire country. While I, for one, welcome our new LED overlords, it’s important for people of all backgrounds to understand what’s going on, process it, and think about what it has to do with sustainable living.

 

Bulled Light Bulb: Form Following Function June 24, 2010

via design-aggregator:

An innovative new LED light bulb design by Jürgen Honold offers a sound compromise for people who embrace the LED lighting revolution and those who prefer the look of traditional bulbs. The Bulled light bulb is an 11 Watt LED replacement for a typical 60 Watt incandescent. Its LEDs are spaced out and built directly into the fins of the bulb-shaped heat sink. (The heat sink is where an LED bulb’s heat dissipates, leaving the light itself cool to the touch.)

Personally, I think the heat sinks make LED light bulbs look edgy and cool. I’m glad this design integrates them into the overall look, rather than hide them. Honold’s design also offers a solution to someone who may be interested in LEDs for energy savings but wants a more radiant, rather than directional, light. The Bulled bulbs should be available on the market (in Europe, of course) by fall 2010.

The beauty in this design (for me, anyway) is how simple it is. If you see the problems people find in the LED bulb appearance, and know a little about how LED lights work, it’s easy to imagine something like this. (But not necessarily so easy to implement.) It makes me want to customize or commission my own LED light bulbs.

 

Melt Bulbs

Artist Keita Ogawa has won the bronze award at the 22nd Koizumi International Lighting Design Competition for Students with this quirky lamp design incorporating LED lights. keita ogawa melt bulbs LEDWaves LED lights

The melting effect serves as a reminder of our diminishing natural resources and urges viewers to consider sustainable energy. I love that Ogawa used energy-efficient LED lights for this design. Although I guess if he’d used actual Edison bulbs not only would that lessen the impact of his message, but they’d heat up and actually melt things!

Unfortunately this lamp is not for sale (yet), but I know I want one!
