Start Developing Snap-in LED Light

It is said from LED lighting company Bridgelux that out with the Edison screw-in bulb and in with the snap-in lighting module.

The Livermore, Calif.-based start-up said Wednesday it has designed a lighting module called Helieon that combines Bridgelux’s LED lights and a snap-in interconnect system made by Molex, which is based in Lisle, Ill.

The interconnect system will make it easy to install LEDs and upgrade them when more efficient or brighter lights come out, the companies said.

The Helion system, which will be available in May for $20, is aimed at lighting manufacturers that build actual lighting fixtures. The Helion will be available with a light output between 500 and 1,500 lumens, the equivalent of between 40 watts and about 100 watts for incandescent bulbs but will use significantly less electricity.

Bridgelux says that the packaging and efficiency of its lighting system is a step toward making LED lighting more cost-effective when compared with other forms of lighting. “Solid state lighting is poised to displace conventional incandescent, fluorescent and other technologies in many high-volume general lighting applications,” Bridgelux CEO Bill Watkins, who joined the company earlier this year, said in a statement .

Bridgelux has signed on some lighting fixture manufacturers to use Helieon, including architectural lighting company Focal Point. But as it goes after the general lighting market, it faces competition from a number of LED start-ups and established lighting companies.

Motion Sensor Light

Make your home safer with a light that comes on when you walk by.

Enjoy instant-on light your home—closet, pantry, shop, garage, basement, garden shed, virtually anywhere! No fumbling for a switch—this battery-powered light detects motion and switches on automatically.

The light is simple to set up and easy to install. And the light comes on instantly and is very bright. Comes on as soon as I round the corner of my house to the front door and it actually brighten the area well.

Having husband with some mental deficiencies from head trauma, he sometimes couldn’t remember how to turn off/on light switches; now no need to worry about him not being able to see when he gets up in the dark; I have not attached them permanently to the wall, just set it on the floor next to baseboard and adjusted with swivel so light shines exactly where we want it.

LED Diogen Lighting to be the Next-generation Light Bulb

Diogen makes the next generation of power-sipping light bulbs: LEDs, short for light-emitting diodes. The unique retrofit design of the Diogen Bulb universally replaces standard incandescent and compact fluorescent(CFL) bulbs and is both UL and CUL certified.

The light output and color rendering of this new bulb is the equivalent of the current 60-Watt incandescent bulb available in the market but uses only 12 Watts of energy consumption.

The Diogen Bulb has a lifespan 40 times greater than incandescent and 6 times greater than the current CFL bulbs offered in the market today and is completely safe and is Mercury-free, unlike CFL products.

The colors are more vibrant than you can get in an incandescent, they use up to 98 percent less power than comparable incandescents, and they have a long life. A string of decorative lights will last forever. It can take 50,000 to 100,000 hours of use, well over 20 years.

Also, LED lights are cool to the touch and don’t contain mercury, unlike CFLs — which requires special handling for disposal.

LED’s last about 40 times longer than regular incandescent lights and six times longer than CFLs currently on the market.

It’s great for us because we can afford to go more green — not only from using less power, but also from being able to have enough power to do a show. And we’re over 50 percent with LED lights in the show.

Make Your Kitchen Glaring at You

Light has been on my mind a lot lately.

Probably, though, it’s because whenever I’m in my kitchen, I am pinned beneath the clinical glare of a monstrous 45-by-16-inch fluorescent light fixture situated over my island. Just a few feet away, a second one (22 by 22 inches) stares down from above the sink. The effect is far from soothing, and in fact rather unsettling, as though my kitchen were a morgue and my island an autopsy table.

The good news, as I contemplate a kitchen overhaul in the (hopefully) near future, is that lighting in kitchens has changed a lot since the previous owner of my home remodeled the space some 15 years ago.

Kitchen designer Mary Galloway of Onesta Design in Alexandria agrees, saying she views the kitchen as a place of many scenes set, in large part, by how it is lit. “You think about someone cooking, someone eating, someone snacking at midnight,” Galloway says. ” . . . Your lighting needs change depending on the scene.”

Recessed lighting, which provides the general lighting in many kitchens these days, has come a long way, says designer Jennifer Gilmer of Jennifer Gilmer Kitchen & Bath in Chevy Chase. Most types now use smaller cans than the once-standard six-inch size, and incandescent bulbs have been replaced by more efficient lights.

Indeed, just as we’ve seen the proliferation of tiny, bright LED (light-emitting diode) bulbs on trees and roofs during the holidays, so are these energy-efficient lights making their way into the kitchen, not only in recessed lighting but also in task and accent lights.

More and more kitchens are also adding accent lights — those that draw attention to a particular appliance or decorative piece, the inside of a cabinet, or the so-called toe-kick space just above the floor — though the latter seems to have its detractors. “I would say that 50 percent of our customers love the toe-space lighting, while the other 50 percent see no point in it,” says Anderson. Its primary function (and appeal) is that it can softly light the kitchen at night, he says.

Pendant lights continue to be popular. They are “a good way to add color and some bling,” Anderson says. Gilmer says the sheer variety in styles makes pendant lighting a good option for almost any kitchen. In fact, it was a pendant light that helped solve a puzzle for one of Gilmer’s clients. “This particular person has contemporary tastes, but we needed something that would fit in with the traditional look of their Georgetown brownstone.” In the end she chose a pair of spare, vessel-shaped frosted glass and chrome pendants to hang above the sink and adjacent cream, black and gray mottled granite countertop.

CRS Elec Lights Turned to New LED Lamp

It was reported from TORONTO that when Manhattan’s tony One Beacon Court on the Upper East Side looked for ways to reduce its energy bill, as part of a much-broader global effort to green the planet, it turned to a small Canadian company for its lighting needs.

CRS Electronics Ltd. (LED.V) based in Welland, Ont., CRS developed, designed and manufactures solid-state lamps that use light-emitting diodes (LEDs) as their light source. It’s a disruptive technology that’s on the cusp of transforming the estimated US$100 billion global lighting industry. If well designed, LEDs can provide light that is the same as or better than conventional light sources, with significant energy and cost savings. According to Strategies Unlimited, a Mountain View, Calif. research firm, the commercial and industrial market for LED replacement lamps is forecast to roughly double each year through 2013.

CRS, whose roots are in school-bus lights, makes a low-watt MR16 LED replacement lamp that replaces halogen technology. MR16s are widely used for accent, task and display lighting in stores, hotels, restaurants, condominiums, commercial buildings, museums and art galleries.

“We didn’t just want to do LED because it’s green, and it saves energy and costs. It also had to have an aesthetic value, and match up with the coloring of the bulb that was already in the hallways. And that’s what we achieved. The bulb itself was just a better product than I could get anywhere else,” he says.

He’s ordered 500 lamps, and expects a 12-to-14 month return on investment, since each lamp can burn for 50,000 hours.

The commercial market for MR16s is estimated to be about US$2.2 billion, according to industry statistics. It’s such a big market that hundreds of upstarts, primarily from China, are popping up, primarily because the lighting giants, such as GE, are looking further afield. “It’s buyer beware. There’s a lot of misleading information out there,” says Mia Paget, who manages the U.S. Department of Energy’s Solid-state Lighting product testing program, CALiPER.

The CRS MR16 is technologically and aesthetically superior, a claim that’s backed up by the results of both independent laboratory and DOE testing.

In May, CRS went public, listing on the TSX Venture Exchange.

CRS, which installed the LED street lamps in downtown Welland, is eyeing the US$61 billion street and area lighting market, where there was 0% LED penetration in 2008, according to an October 2008 Navigant Consulting report.

Green Mountain Power Plans to Go LED

As we all know that new lights that save energy and lower emissions might be coming soon to a street near you.

Green Mountain Power plans to replace worn-out street lights throughout its service area with energy-efficient, long-lasting LEDs. The LED lights have a life span of more than 25 years, compared to the 5 to 7 years for traditional street lamp bulbs.

LEDs are traditionally used in Christmas tree lights, newer flash lights and basketball scoreboards. They use a different technology from standard incandescent bulbs.

“By reducing the amount of electricity that you use by more than half, it eliminates any environmental effects that will be needed to produce that power,” said Dotty Schnure of GMP. “Also, with the lights they’ll be replacing, mercury lights, those lights have mercury in them and have very specific disposal issues. With LED, we’ll be avoiding all the mercury disposal issues.”

GMP submitted the plan to the Vermont Public Service Board. If approved, the lights could be installed as early as March 1.

Supertex LED Driver Uses Closed-Loop System to Deliver Maximum LED Light Performance

It was reported from SUNNYVALE, CA on Feb 17 that supertex /quotes/comstock/15*!supx/quotes/nls/supx  (SUPX  25.70, +0.05, +0.19%) , a recognized leader in high voltage analog and mixed signal integrated circuits (ICs), today introduced the HV9963, a closed-loop LED driver IC with pulse width modulated (PWM) dimming capability designed to optimize LED performance and efficiency and extend LED life. The IC excels in DC/DC applications such as RGB or white LED backlighting, LCD TVs and monitors, and LED lamps for general lighting.

The HV9963 utilizes a closed-loop system to control the current going to the LED string, which is an active, real-time system that continuously monitors the LED current via sense resistors. The HV9963 includes a 1.0MHz transconductance amplifier with a tri-state output, which closes feedback loops in the sensing process and provides accurate current control. It can be synchronized in applications requiring multiple LED drivers to prevent the system sub-harmonic oscillations that are often associated with driving multiple driver schemes.

The HV9963 also features hiccup mode protection for both short- and open-circuit conditions, and a high PWM dimming ratio. The IC operates in a constant frequency mode for use in a variety of converter topologies such as buck, boost and SEPIC.

“The HV9963’s closed-loop system enables accurate line and load control of the LED current over its entire operating range,” states Ahmed Masood, Vice President of Marketing for Supertex. “This IC also includes controls that allow PWM dimming at very low duty cycles, resulting in a contrast ratio of up to 5,000:1.”

The HV9963 is available in a 16-lead SOIC package (HV9963NG-G). The part is RoHS compliant. Samples are available from stock. Lead-time for production quantities is 4-6 weeks ARO. Pricing is US$0.85 each for the HV9963NG-G in 1K quantities.

About Supertex Supertex, Inc. is a publicly held mixed signal semiconductor manufacturer, focused in high voltage analog and mixed signal products for use in the medical, LED lighting, imaging, industrial, and telecommunication industries.

New Greensburg City Hall sign Plan to Use Solar Lights

It was reported that a new Greensburg City Hall sign has been under way for a couple of weeks, but a lot of the final pieces came together this week.

First came the LED light bars, unwrapped by Curtis Shaddox, president of Kansas City-based Sunpower Sign. Brian Eliot, manager of the Sign House in south Salina, grabbed a 12-volt power pack from a cordless tool and touched the leads on the light bar to the contacts to make sure it worked.

The permanent power source arrived with Sunpower executive vice president Troy Haefner from Minnesota, who carried a roll of flexible solar film wrapped around each arm.

Like much of the rest of rebuilt Greensburg, the new City Hall sign packs some serious environmentally friendly tech: the LED lights will use a fraction of the power a bank of fluorescent tubes would, and the solar film will power it.

The Sign House has been using LED lighting on some signs for about five years, Eliot said, “But this is our first experience with solar power. It’s very new for the industry and definitely for this area.”

The sign was scheduled to be delivered to Greensburg on Friday, though it won’t be permanently installed until warmer weather, when the concrete base can be poured.

The design calls for a bank of LEDs at the top and bottom of the sign, illuminating the lettering and pushing light through a frosted acrylic layer near the top, causing a “glowing halo” effect, Eliot said.

Shaddox said the LEDs will have a 15-year lifespan, as opposed to about five years for a fluorescent tube — and there’s no ballast to go bad.

Eliot said solar-powered signs will likely become an important part of his company’s business, and he and his employees are having fun learning about the new technology.

The flexible solar panels are also a relatively new technology and are starting to replace older designs, which are heavier, bulkier and more fragile.

And, Shaddox said, the thin film will generate power in almost any light.

“You don’t need full sun, and it doesn’t have to be tilted at 30 degrees south to get the right angle,” he said, explaining those benefits allow for more design possibilities. “Instead of this big panel standing there, we can just apply it to the top of the sign.”

NASA and the military have used flexible solar film for several years, but as more companies start producing it, the price is dropping to where it’s cost-effective.

“The cost per kilowatt is dropping every week,” Shaddox said.

The adhesive-backed solar film has about a 25-year lifespan, Shaddox said, and is much more resistant to damage than more traditional photovoltaic panels.

“You could take a box knife and cut it, and that one area won’t work any more, but the rest of it will,” he said. “And, it’s got a teflon coating, so you can spray-paint it and just clean it off.”

A combination of advances in solar power and LED technology makes such signs possible, Shaddox said; it wouldn’t be practical to try to power a fluorescent-tube sign with solar panels.
