Artificial Moon in Xujiahui Park

“Artificial Moon” by Wang Yuyang uses various fluorescent light bulbs to create a400 cm (>13 feet) representation of our moon, complete with representations of craters, maria, and rims. Even stronger than the piece itself to me is the choice of location for this piece in 2008, Xujiahui’s park, one of the last remaining park areas in the city. Due to light pollution the moon can rarely be seen in the Shanghai skies, which makes this representation so much more powerful. It has since 2007 been displayed in other locations as well. Check it out!

 

Thanks, Art Hub Asia and Transmediale!

Dianne Harris at the Kinetica Art Fair 2011 in London

I ran across this very cool art installation while looking up info about the Kinetica Artfair in London – an artist named Dianne Harris had some pretty incredible fluorescent sculpture to see and appreciate.

Listen, you have to check out Dianne’s website – I kinda want to buy this woman a drink!

Check out some images from her work at this year’s Kinetica Artfair:

Filament Lamps – from Scott, Rich, and Victoria

Everybody’s pal (and BIRTHDAY BOY TODAY, November 3, 2010) Aron Altmark sent me a link to these great lamps by design firm Scott, Rich, and Victoria – they’ve taken fluorescent tube stock and turned it into a new recreation of the idea of the old carbon filament lamps from the days of Edison and Swan.

Cool!  Check out these pictures:

My only criticism?  Color temperature.  But they probably weren’t going for that.

I still think these lamps are incredible cool.  No pun intended.

Mr. Light, That’s My Name – That Name Again is Mr. Light

mr light

Tomás Alonso has created the Mr. Light series of lamps – not unlike the Plof lamp from Yonoh, but not totally like it either.  Mr. Light is designed around the new LED version of the T-8 fluorescent, and makes the LED T-8 the centerpiece of the fixture.  I like the form of the function – my concern would be spillage.  I’m one of those people who actually enjoys designing with fluorescent sources, but only when I can control the field angle.  All that being said, this is a pretty clever light, and I’m digging it.

Induction Lighting – 100,000 Lamp Hours

I have read a lot about the plasma column lamps created by companies like Luxim and Ceravision – electrodeless, high CRI, very efficient, and high lumens per watt.  The sources use radio waves to excite the argon and metal salts in the arc tube to a plasma – in an electrodeless situation.  The idea of the magnetic induction moved into fluorescent technology a while ago, yielding a 100,000 hour flurescent lamp.  There are several companies marketing products in this fluorescent technology – it has a high CRI (94+ in most cases), power efficient, and with good lument maintenance (you know, given the lack of electrodes and all).

The fluorescent induction technology uses the UV light that is returned to the ground state in the plasma material to excite fluorescent phosphors in the lamp.  They still use Mercury (yeah yeah, I know) like the regular fluorescent process, just a different way to excite it.  One of the companies marketing a product is Everlast Induction Lighting – the sales guys there made some videos (thanks for doing this, guys!), and one of them explains a bit about the induction technology.  The video:

Do you remember the article I posted a while ago about the guy (Richard Box) who created an installation of fluorescent lamps just stuck into the ground under a high power transmission line?  The fluorescent tubes all just glowed like they had power – the process of the magnetic induction fluorescent is similar – an electromagnetic field excites the phosphors.

The companies selling the flurescent induction products offer dimmable versions of the sources – have you designed any lighting systems using this technology?  Have you tried any of these products from any company marketing the fluorescent induction lamps?  Please post in the comments!

The Neo from Se’Lux

I originally read about the Neo wall, ceiling, and pendant fixture from Se’Lux through LightNOW, but I couldn’t figure out what was so great about a fixture that uses a regular ol’ T-5 fluorescent tube – so I looked into it a little further, and they’re actually quite interesting.

First, from Se’Lux’s mouth:

NEO® Systems- A new generation of interior luminaires constructed of glass and polished aluminum. Neo® is developed with a dedicated systems approach for total design freedom and specification flexibility for suspended, ceiling mount or surface mount applications. Precision reflector and Microprism diffuser technology is utilized to optimize output of T5 fluorescent sources. The utilization of all visible light is the key to the NEO® luminaire philosophy.

The fixture itself is an enclosure of sorts – the Neo offers a pendant, wall, or ceiling mounted style, and has two options for diffusion – a microprismatic diffuser or an opal lens:

They’re simple looking fixtures with a lot of sophistication.  Check out the rest of the line here.  Beautiful work, Se’Lux.

LED Fluorescent Replacement Lamp

fluor2

A Japanese company called Toshin Electric has released an LED fluorescent replacement tube called the “Bikei,” and it fits an existing 40W fluorescent socket.  The specs on this lamp are interesting; 120 blue LED chips, CRI of about 90, and 40,000 hours projected lamp life. Existing LED fluorescent tube type lamps are running a CRI of about 70, but normal fluorescent lamps are between 84 and 88 (Ra).  What’s this saying?

It’s saying that the existing LED fluorescent tubes ain’t cutting it, right?

Bikei’s luminance is about 370lx at 1 meter under the lamp, according to Toshin Electric.  Toshin also says that their lamp’s luminance is about equal to a 40W straight tube fluorescent lamp.  Toshin is expecting this new source to be used in places that would utilize this type of fluorescent source – parking lots, tunnels, factories (high bay?  I don’t see it) and stores – as a few examples.

The lamp is going to start shipping at the end of this month (February 2009), and is running about $306 dollars.

Smart Lite – Use That Ballast!

As we know, CFLs are certainly more efficient and longer lasting than incandescent lamps in most cases.  We also know that CFLs have that lovely Mercury issue, and recycling them can sometimes be a major pain in the rear.  Another thing you might not know is that the compact fluorescent lamp also has a weird two component-one-piece design with a bulb (the glass envelope, the curly thing) and a ballast (down near the screw base).  In essence, the design makes sense:  a powerplant/starter and a fluorescing source.

Right?

Well, think of a typical fluorescent fixture, with four foot tubes.  When you replace a tube, you’re just replacing the light emitting part, not the whole ballast.  If you’ve ever changed out a ballast, you’d know that it’s buried up inside the fixture, and not that easy to access.  The other bit of weirdness with the ballast is that they will last upwards of 50,000 hours – but the fluorescent bulb lasts upwards of 5,000 hours.  CFLs are the same way – the ballast WAY outlasts the bulb, by a factor of ten.  So most times you chuck a CFL, you’re throwing away a spent bulb and a usable ballast.  This isn’t always the case, but most times it’s the case.

A company called 3E Technologies has invented (but unfortunately not yet produced for sale) a CFL that they called the Smart Lite, with an efficiency of 65 lumens/watt, or a 62.5% improvement over existing CFLs.  The best thing about thew Smart Lite?  When the bulb stops working, you twist it off of the ballast, recycle that sucker, and twist a new bulb onto the ballast.  Smart Lite claims a 50,000 hour ballast and 10,000 hour bulbs.

It’s a start!  There’s a video on the 3E Technologies website for Smart Lite – it’s quick, but it shows how the Smart Lite bulb replacement works.

The Cordura Lamp – Stephanie Jasny

Stephanie Jasny‘s Cordura Lamp is a melding of form and function, inspired by objects used in construction sites.  The Cordura Lamp is the lovechild of a spotlight and a cable reel – the cable is wound up onto the outer casing of the spotlight, and the lamp provides ten meters of lead for you to plug in somewhere in reach.  The Cordura Lamp also has a pivotable mount, making the lamp pretty flexible.  It’s powered with a fluorescent source.

The lamp is so pretty, I’d want to keep it as far away as possible from my workshop!  Oh well, form and function, right?

Thanks, Yatzer!
