Philips TLED lamp prototype combines efficiency, brightness and warmth

Philips combines efficiency, brightness and warmth in LED lamp prototype

We know what you're thinking: "light bulbs? Yawwwwn." But we'll say this, Philips has done something pretty impressive and interesting with its TLED prototype lamp. Generally LED bulbs use either a combination red, green and blue LEDs to create white light, or they use a phosphor coating (more common) in combination with a blue LED. The problem with the latter is that it tends to generate a very cool light with a blue tinge, while the former is less energy efficient because of their reliance on green LEDs. Philips' solution is to combine two blue and one red element, but use a green phosphor filter to convert one of the blue LEDs to green. The result is a relatively warm light, between 3,000 and 4,000 kelvin, that generates more than twice as many lumens per-watt as Philips' current LED bulbs. In theory, a 7.5-watt TLED could generate as much light as a 100-watt incandescent bulb. With any luck the tech should hit the market sometime during 2015, but it'll be primarily for office and industrial application at first -- so don't start tossing your CFLs just yet.

Scientists build ‘super-bulb’ out of plastic, it’s (apparently) fantastic

Scientists build Fipel superbulb out of plastic, makes Edison blush

What do Michael Stipe and Dr. David Carroll have in common? Neither of them like the "fluorescent, flat, caffeine lights" that fill our offices and public spaces. Unlike R.E.M.'s lead singer, however, Carroll is actually trying to do something about them. His team has developed a plastic bulb made out of field-induced polymer electroluminescent technology (Fipel) which emulates sunlight rather than the headache-inducing blue glow we all know and despise. The team from Wake Forest University, NC, believes the tech is a perfect solution because it doesn't get hot, doesn't contain mercury and won't shatter like glass. At least one company is already interested in producing an initial batch, and there's a chance we'll see them before we get desperate and spend $200 on a lightbulb that interacts with our smartphone.

Lumen Color Changing LED Light Bulb Goes with Bluetooth, Not Wi-Fi

Posted on by

A couple of months ago, the LIFX LED lightbulb debuted on Kickstarter, and it was only a couple of weeks ago when electronics giant Philips unveiled its Hue color changing LED light bulb. These light bulbs not only allow you to choose whatever color you want using a smartphone application, they also allow you to turn the light on or off at pre-set times, making for built-in home automation. These bulbs require an in-home Wi-Fi connection and come with a special bridge you have to connect to your network. Now, a competing product has turned up on Indiegogo called the Lumen Bluetooth LED bulb.

Like the LIFX and the Hue, the Lumen bulb will use an app that controls the light brightness, color, and can turn the lights on or off. Inside the bulb, its RGBW LED array lets you create any color you desire, including pure white. However, the Lumen operates on Bluetooth instead of Wi-Fi. This lets you use the bulbs without an existing wireless network, but limits its range to 30 feet. This might be okay for apartment-dwellers, but it’s not so great if you live in a larger dwelling.

The bulb also has four special operating modes. The modes include Party Mode that flashes the light bulb and changes color to the music. Sleep Mode is designed to simulate moonlight. Lake mode helps you get out of bed in the mornings by waking you to gradually brightening light rather than the alarm. The Ambient Mode creates romantic soft and dim lighting.

An early-bird special will get you one Lumen bulb for $49(USD). Two bulbs will cost $99, 10 sell for $450, 25 cost $1000, and 100 of the bulbs will cost $3500. The project still has 30 days to raise the funding needed, and is seeking $110,000 in funding, and has so far scored only about $1300. If you prefer Bluetooth to Wi-Fi, head on over to Indiegogo and reserve yours now.


GreenWave Reality ships WiFi-aware light bulbs that flick on through motion and smartphones

GreenWave Reality ships WiFi light bulbs that flick on through motion and smartphones, join the 21st centuryWe've seen connected light bulbs before, some more sophisticated than others, but they're rarely as straightforward as GreenWave Reality's just-shipping Connected Lighting Solution. Eco-friendly LED bulbs in the lineup include support for WiFi and are immediately controllable from a smartphone or tablet as soon as they're receiving power. Basics controls like group presets and timed lighting are just the start; if you're not worried about leaving anyone in the dark, the bulbs can respond to motion sensors and only illuminate the rooms that need attention. And while the intelligence isn't new in itself, GreenWave would argue that sheer accessibility gives it an edge, with electric utilities in Denmark, the Netherlands and Sweden skipping the retail middleman by selling directly. Don't despair if you live in the US: the linked-up lighting is cleared for eventual use by Americans who'd like to save both energy and a trip to the light switch.

LIFX: Smartphone-Controlled LED Lightbulb: There’s An App For That!

Posted on by

Have you ever wanted to control the lights with your smartphone? Now you can, thanks to LIFX Smartbulbs. There have been already some LED lightbulbs that could be controlled by a remote. Now, you can use an app to control the mood of your room – or your entire house – from the comfort of your phone.

LIFX Smartbulbs are naturally energy efficient. One LIFX smartbulb will last 40,000 hours or 25 years, and reduce power consumption by up to 20% from conventional bulbs. Bulbs can be turned off and on, and change the color of the glow to suit your mood. And unlike some remote bulbs, you can control multiple bulbs and multiple locations from a single smartphone iOS or Android app. The app can also match the mood of your tunes, wirelessly. It will beatmatch the music that you are listening to.

The bulbs are also able to detect when you arrive home and turn on the lights for you, and can even be programmed to wake you up naturally, gradually glowing brighter and brighter.

LIFX was launched as a Kickstarter project, and at the time of writing, it had amassed over $1,100,000 of a humble goal of $100,000 – with 55 days of funding left. Needless to say that this project will be made. You’ll have to pledge $69(USD) to get one bulb, or $119 for a pair, or $196 for four bulbs. Further discounts are available for larger quantities. Expected delivery for the LIFX smartbulb is March 2013.

Bluetooth Bulb lets you switch on, time, dim and color your lighting with your phone video

Every once in a while, someone tries to give the humble light bulb a little next-gen flavor. This time, we're adding Bluetooth 4.0 to the mix. Why, you ask? Good question, and one with a simple answer. The Bluetooth Bulb lets you pair your phone with one or more of the lights in your home, and then control them via an app. Switch them on, off, change brightness, set a timer, and a special RGB bulb even lets you change the color ambiance. If you're worried about the cost and waste when these things burn out, fear not, as apparently every part is replaceable -- and as there's no home automation system involved -- you won't need anything else to get set up. If this idea switches you on, you might have to hold out a little longer, as the product is just a patented prototype right now. Sights are set on mass production, but you'll have to stick with your old clapper for the time being.

ARM forms UK group to foster an Internet of Things, put 50 billion devices online by 2020

ARM isn't content with dominating the mobile space. It's been by the far the most vocal about an Internet of Things where everything is connected -- and to make that happen, it just established an industry forum in the UK that it hopes will establish common ground for all those internet-linked light bulbs, refrigerators and thermostats. Home energy firm Alertme, cloud-aware sensing outfit AquaMW, lighting maker EnLight and white space wireless guru Neul will start meeting with ARM from August 24th onwards to hash out our automated, eco-friendly future. There's a certain urgency in this for the chip designer: it expects 50 billion devices on the grid by 2020. With IDC estimating a billion new connected devices just in 2011, the clock on that connected device transition is ticking very loudly.

INSTEON says apps are better than switches with networked LED bulbs

INSTEON says apps are better than switches with networked LED bulbs

We'll spare you the puns and meme references here. (Besides, how many Xzibit jokes can you take?) INSTEON has decided that simply saving you money on your electric bill isn't enough anymore. If you're going to cough up nearly $30 for an LED lightbulb, there better be some value added features. So, the company stuck a proprietary dual-band wireless receiver inside each of its eco-friendly lights allowing them to connect to a home automation system. There is a dedicated remote you could buy, but why bother when there's an app available for both Android and iOS that lets you turn on, off and dim the lights from the comfort of your touch screen. You can even create custom "scenes" for preset lighting levels. Unlike most remote lighting solutions, though, all the necessary hardware is built into the bulbs themselves. In fact, each one acts as a signal repeater, passing along instructions both wirelessly and though the powerlines to make sure ever corner of your home is covered. For more check out the PR and video after the break.

Inhabitat’s Week in Green: Jake Dyson’s lamp, wooden light bulbs and weed-killing lasers

Posted on by

Each week our friends at Inhabitat recap the week's most interesting green developments and clean tech news for us -- it's the Week in Green.

wooden light bulb

This week Inhabitat has been reporting live from New York Design Week, where we've witnessed countless innovative green designs from around the world. To kick things off, we were pretty impressed with this desk lamp designed by Jake Dyson (son of the vacuum god) that extends the life of its LED bulbs by a whopping 37 years. Also in the category of "bright shiny things we love" is QisDesign's Aurelia lamp, which bears a striking resemblance to a glowing jellyfish. We were also dazzled by UM Project's collection of retro, robot-inspired lamps, Light & Contrast's cute LED flower lights, and we were absolutely floored by Alessandro Jordão's larger-than-life LEGO chair. Can't get enough of NY Design Week? Check out all of our favorite green designs from this year's shows.

Continuing with the topic of innovative green lighting technology, artist Ryosuke Fukusada has created the impossible: a glowing wooden light bulb. Confused? The light was created using a technique called Rokuro, and it consists of an LED light bulb wrapped with a very thin layer of wood. When the bulb is turned on, it illuminates the grain of the wood. As Fukusada's creation demonstrates, LED lighting technology has taken some incredible strides recently, and we took some time to round-up 24 of our all-time favorite green lamps that look great with LED bulbs.

Panasonic sends 100,000 LEDs down Tokyo river, mates tech with tradition (updated with video!)

Panasonic sends 100,000 LEDs down Tokyo river, mates tech with tradition

If you'd been by the shore of the Sumida River in central Tokyo this past weekend, you would have noticed that it was glowing a distinct shade of blue. That's because Panasonic decided to kick off the first-ever Tokyo Hotaru (fireflies) festival by sending 100,000 EVERLED light bulbs down the river, both to mimic fireflies as well as to pay homage to a Japanese tradition of floating candles on the water. Before you cringe too much at the thought of the environmental impact, rest assured that Panasonic minimized the footprint of its aquatic LED parade. All the bulbs ran on solar power (presumably, charged during the day) that kept Evolta batteries fed inside, and the entire lot was scooped up in a large net afterwards. We love the exhibition as a large-scale demo of sustainable lighting -- you may just want to avoid fishing along the Sumida's shoreline for awhile in case you catch a straggler.

Update: We've found a video of this spectacular event -- check it out right after the break.
