Energy Star proposes to revert to 120 Hz for LED lamps

1月 29th, 2010
A change to the requirements for replacement LED lamps is proposed in response to industry feedback.
EPA is proposing to an amendment to the Energy Star program requirements for Integral LED Lamps, published on December 3, 2009, which will change the LED Operating Frequency requirement from ≥150 Hz to ≥120 Hz.The ≥150 Hz requirement has been challenged by a number of companies and Energy Star stakeholders.

A letter from Alex Baker, EPA’s Lighting Program Manager for Energy Star, invites comments on this proposed change by Friday, February 12, 2010. Please send written comments to Kate Buck.

If accepted, the proposed change will result in a new version of the specification, Version 1.1. The effective date of the specification, August 31, 2010, would remain unchanged. The letter says:

“The performance requirements laid out in the Energy Star specification for Integral LED Lamps (V1.0) are intended to ensure that qualified products are energy efficient and meet user performance expectations. One of the requirements contained in the criteria document is for minimum LED operating frequency. This requirement was intended to mitigate potential health and safety problems caused by visible flicker. Feedback from industry stakeholders on earlier drafts of the integral LED lamp criteria was minimal and inconsistent, suggesting alternative frequency requirements ranging from 100 Hz to 500 Hz.

“In the final criteria published December 3, the minimum LED Operating Frequency requirement was increased from the previously proposed 120 Hz to 150 Hz in an effort to address stated industry concerns. However, subsequent industry feedback has indicated significant concerns exist about this higher requirement, citing cost and design implications, and the exclusion of products using AC-driven LEDs. Further, several stakeholders state the requirement as written is inadequate to prevent visible flicker and potentially should address modulation depth, waveforms, duty cycle, and other characteristics, in addition to frequency.

“EPA seeks to address this issue in close cooperation with the Department of Energy, industry and standard-setting organizations to achieve the following objective: Energy Star qualified lamps do not exhibit visible flicker during full output or dimmed operation.

“An IEEE working group including leading human factors experts is working to develop Recommended Practices of Modulating Current in High Brightness LEDs for Mitigating Health Risks to Viewers, but the results of this work likely will not be available until next year.

“To avoid delays in the implementation of the Energy Star specification for Integral LED Lamps, we propose reverting back to a ≥120 Hz requirement, pending the completion of further research on this topic.

“Stakeholders are advised that EPA intends to again address visible flicker concerns once industry consensus measurement methods and recommended performance thresholds are available. If additional changes are warranted, they will be proposed and finalized through a stakeholder process, allowing adequate time for transition.”

Solid State LED Lamps target grocery retailers

1月 29th, 2010

American Bright has expanded and improved their innovative solid state replacement lamp capable of replacing inefficient florescent tubes in grocery retailers world-wide.

Chino, Ca. - American Bright Lighting, Inc. today announced its new patent pending, second-generation SimpleTube LED replacement lamps capable of replacing inefficient T-8 fluorescent tubes in large-scale retail refrigerators and freezers. The Improved series offers up to 79% power savings over the commonly used fluorescent tube ballast combinations and, due to lower heat emissions, reduces strain and demand on refrigeration compressors and controls. The series is the industry’s most efficient, consuming as much as 50% less power than comparable LED units from other manufacturers. Additional benefits of the second-generation SimpleTube lamps are longer lifetimes, lower maintenance costs, comprehensive five-year warranty, and significantly better lumen maintenance over the service life.

Independent laboratory testing performed to LM79 confirms an efficacy of up to 61 lumens per watt. The total efficacy of the SimpleTube is nearly twice the efficacy of the other solid state lighting products commercially available for similar applications. SimpleTubes are UL listed, assuring compliance will internationally recognized safety standards, and they are offered in ANSI color bins. The color quality and consistency enhances product appearance and will not degrade appreciably over the 50,000+ hour projected life of the product. The simple tube is available with a number of output angles and lens options, both clear and frosted, to meet the most demanding applications.

American Bright Lighting has also introduced a THD (total harmonic distortion) correction version that complies with emerging regulations and proposed Department of Energy (DOE) specifications. This patent pending feature assures end users of compliance with existing and future regulations regarding the use of AC based LED systems. AC bases LED systems eliminate the need for AC to DC power conversion and secondary driver systems that historically are the “weak link” in other solid state lighting solutions. This innovation keeps the SimpleTube product family ahead of all competing LED products.

Unlike fluorescent lamps which contain significant amounts of mercury and in various areas must be disposed of as hazardous waste via a fluorescent recycling firm, SimpleTube lamps are 100% RoHS compliant, meeting the most stringent global standards for toxin-free materials and manufacturing processes. The toxin-free nature of solid state lamps also renders accidental breakage concerns a thing of the past. When a fluorescent tube is broken in a freezer or refrigerated retail space, all the contents must be discarded, which carries a high cost in not only lost product, but also in lost productivity.

“With average power prices to grocery stores rising in cost by as much as a factor of 6.7 many grocers are looking for other ways to cut costs while still meeting customer expectations,” George Lee, President of American Bright Lighting, noted. “Utility costs can amount to as much as 13% of a retail location’s overall operating expenses,” Lee added. “The Second-Generation SimpleTube addresses not only the environmental concerns that fluorescent tubes create, but also the bottom line reality of rising energy costs,” he concluded.

A white paper report that includes general specifications and related documentation is available from American Bright Lighting directly. This highly detailed white paper contains relevant details (and quoted sources) on the retail lighting market, energy costs/savings, light output of competitive models as well as a number of useful formulas for calculating a return on investment (ROI).

Technology and Applications of LEDs

1月 29th, 2010

Zumtobel has formed Ledon Lamp GmbH as a sales company for LED lamps, and has announced a development partnership with Lemnis Lighting B.V.

Zumtobel Group, the Austria-based lighting company which specializes in professional light fittings, lighting solutions and lighting components, is set to enter the lamp business for the first time, via the LED retrofit market.

The Group has founded a subsidiary, Ledon Lamp GmbH, based in Dornbirn, Austria, which will promote the sale of a broad portfolio of LED lamps. The product range will focus on retrofit LED lamps to replace conventional incandescent light bulbs (e.g. with E14 or E27 screw caps).

“LEDs are where the future lies,” said Zumtobel Group CEO Andreas Ludwig. “We have built up a leading level of expertise in this technology and we’ll be making use of this knowledge to supply high-quality light bulbs to consumers.”

The LED technology for these lamps will be supplied by the Zumtobel Group subsidiary Ledon Lighting Jennersdorf GmbH, which supplies the Zumtobel Group brands with LED modules and components. The core competency of Ledon Lighting is described as “high-quality white light from LEDs, with expertise in warm-white LEDs and stable, homogenous color distribution.”

Sales of these high-tech LED lamps (initially 5W, 6W and 6W-dimmable versions) will be via retail outlets, such as DIY stores, as well as from sales partners across Europe. Ledon Lamp GmbH is headed up by Detlef Mikulsky and Peter Petz.

Ledon Lighting began production of LED modules for use in retrofit lamps as early as 2008, and has supplied chip-on-board modules to lamp makers such as Lemnis Lighting (see photo). Modules with an efficacy of 100 lm/W and CRI of 90 at 2900K enable lamps with an efficacy of 65 lm/W.

Co-operation with Lemnis Lighting B.V.

Zumtobel has also concluded a development partnership agreement with the Dutch company Lemnis Lighting B.V, which markets various LED retrofit lamps under its Pharox brand name (see also the Lemnis press release).

Lemnis and Ledon will jointly develop a full-line portfolio of technologically advanced and high quality LED-based lamps for residential and professional use. The lamps, designed to replace not only conventional light bulbs but also halogen spots, is to be marketed by both companies under the Ledon and Pharox brands.

Under the terms of the agreement, Zumtobel Group companies are also defined as a preferred supplier for Lemnis Lighting.

“Ledon and Lemnis are the perfect partners to drive the breakthrough of the LED lamp,” said Zumtobel’s Ludwig. “Our joint strategic goal is to build up a significant volume of business in the lamp market.”

Lemnis Lighting CEO Remko Gaastra described the deal as “a further step in our strategy to form strong partnerships with key players in the industry to enable fast technology and product development.”

New Eco-Friendly Decorative LED Lamps from NxGen Technologies

1月 29th, 2010

NxGen Technologies, Inc. has developed environmentally-friendly, replacement lamps for the S14 shaped incandescent light bulbs commonly found in decorative lighting applications. The lamps consume less than one watt of electricity compared to as much as the 11 - 15 watts normally consumed by incandescent bulbs of this type, while giving off the same amount of light.

“These bulbs have been designed to pay for themselves with energy savings in less than one year, depending upon local electricity rates,” says David Allen, president of NxGen Technologies. “This is very important to users who do not want to spend more money in order for their businesses to ‘go green.’ And, the lamp has been designed to last up to 40,000 hours – this amounts to an enormous energy savings over a very long period of time.”

The S14s developed by NxGen Technologies come in all of the popular transparent and opaque (ceramic) colors and, according to the manufacturer, are indistinguishable from their incandescent counterparts. “The ceramic red, yellow, and white colors appear identical to the incandescent bulbs in a side-by-side comparison while the ceramic blue and green are clearly brighter and more vivid than the incandescent bulbs,” adds Mr. Allen.

Common applications for the S14 include decorative lighting found in restaurants, bars, theater signage and marquees, shopping malls, casinos, shop windows, festivals, and amusement parks. “Amusement parks are a good example,” continues Mr. Allen. “An amusement park that uses 10,000 or more lights can save more than 100,000 watts of electricity per hour (10.4 watts per lamp per hour). Savings such as this really add up,” Mr. Allen concludes.

Element LED lamp uses 7 watts and lasts 30 years

1月 29th, 2010

It’s not often that a lamp that isn’t a dock gets written about in a tech story, but the uniqueness of this LED is just so cool and innovative that it is just impossible to ignore. Don’t let the $338 price tag scare you, it is actually worth it to many and surely provides a wow factor for any desk oriented exec.
This lamp claims to be the first light of its kind to meet all the Department of Energy’s criteria for an LED task light. That and it is gorgeous in a high tech sort of way.
Element’s breakthrough technology makes a usable white light from an LED; its “MCX LED Technology utilizes a single multi-chip LED that produces a large footprint of bright neutral-white 3500 Kelvin light that meets guidelines for comfortable ergonomic reading”. This is different from other LED lamps that use more than one LED which in turn throw multiple shadows.

The cool LED (literally and figuratively) is rated for 60,000 hours or 6.8 years of continuous use. Put another way, if you use it for 8 hours a day, you won’t have to mess with it for 30 years. After that you can actually replace the chip. Assuming they still make them by then. This too is novel as all other LED lamps make you throw the whole thing out when it dies. Of course did I mention all this sucks only 7watts of power to throw the equivalent lumens of a 70watt light bulb? Since this going to be around for the next 30 years or so, be happy it is made of aluminum (81% recycled) so it should hold up its finish.
The lamp comes with a 10 year warranty on all components and a variety of plugs for international use in case you get transferred to China. The lamp comes in all silver or silver with white trim (to match your Mac?). As far as moving it around—for all you diamond setters, it has 135-degree front-to-back head tilt, 90-degree side-to-side head rotation and 360-degree swivel from the base. Its dimensions are: 18-28″w x 18-28″h with an 8-inch-diameter base. At the moment it is only available through a few places and is supposed to cost $338, but we found it for $237 at www.worksafetech.net. But wow, will you get a lot of mileage from the eco planet saving cool geek factor.

How OLMI stretch ceilings can prevent burst water pipe damage

1月 29th, 2010

A lot of private houses, schools, offices, and other premises suffered tens of thousands of euro worth of damage as a result of burst water pipes during the winter holiday season.

OLMI could not prevent bursting of water pipes, but stretch ceilings could prevent the rest of the damage caused by collapsed ceilings and water flood.

OLMI stretch ceilings can easily hold more than 25 gallons of water, and once the water is removed the ceiling will return to its original shape.

In addition, it would be much easier to access those pipes located over stretch ceiling systems rather than pipes located over plaster board ceilings.

And of course, the other advantage of OLMI stretch ceilings is its beautiful design.

 

What is a stretch ceiling system?

A stretch ceiling is a suspended ceiling system consisting of two basic components – a perimeter profile and a lightweight membrane which stretches and clips into the track. In addition to ceilings, the system may also be used to create wall applications, ceiling and wall murals, suspended 3-D panels, or freestanding features. They can be given virtually any shape. Stretch ceiling systems allow the incorporation of all types of light fixtures, grilles, sprinklers, etc.

The track enables curves, domes, vaults, and many other shapes to be formed, which are particularly impressive. The stretch ceiling is mounted by trained installers who specialise in this kind of ceiling installation.

OLMI can offer you a stretch ceiling in many different colours and finishes including matt, satin, lacquered (reflective), perforated, suede, metallic, and translucent (for light diffusion, backlighting, projection). Effects can be produced with colour changing LED lights.

Recessed lights, chandeliers, track lighting, and fibre optics can easily be incorporated with any of the colours and finishes.

The stretch ceiling can be formed into three-dimensional shapes, suspended from cables, installed wall to wall, or placed as ceiling panels.

It can be printed or painted for additional effects, is entirely waterproof, washable, and is maintenance free, hygienic, and non toxic, antistatic, and non-allergic. Installation can be carried out in a few hours and does not require the removal of furniture. The ceiling can be quickly removed and reinstalled with no mess. 

The unique stretch ceiling system offers a fantastic opportunity and the freedom for an added dimension in design potential. The versatile profile system allows the ceiling to be installed as a simplistic flat ceiling or in varying forms such as pitched, curved, vaulted, domed, 3-D, or circular. This distinctive system offers a palette of colours, choice of texture, and has the ability to create clean and cool or loud and colourful ceiling features and lighting effects.

 

Finishes

Lacquered finish is the most popular option for kitchen, living room, bedroom, and bathroom ceilings, as it makes any room appear larger by creating a perception that the roof is higher. Suede finish is widely popular for home office and bedroom ceilings. Translucent ceiling is common for areas where the entire ceiling should be backlit. Satin and matt finishes are most suitable for classic living and dining room ceilings. Metallic and perforated finishes for high tech design can be used within your home or apartment ceilings to achieve special effects.

 

Benefits

Individual design and colour scheme, it improves the quality of thermal and sound insulation, hides water stains on the ceiling or walls, never cracks, is easy to clean, protects your home or apartment interior from water damage, and is quick and clean installation without mess and dirt in your premises.

 

Supplier

As the stretch ceiling concept is a relatively new concept in Ireland OLMI invite you to its showrooms to speak to one of the designers and to view the ceilings on show. A free quotation service is offered to all customers.

Designs are matched to your needs and budget. You will receive a high quality product at an affordable price, with a 10 year guarantee on all elements.

Cree triples its profits

1月 29th, 2010

Shares of LED lighting company Cree rose as much as 10 percent in after-hours trading Tuesday after the company posted quarterly results that left analysts’ expectations in the dust.

“The results were spectacularly better than what we were looking for,” Morgan Keegan & Co. analyst Harsh Kumar said.

Cree, which has its headquarters in Durham, also raised its guidance for the current quarter beyond the expectations of Wall Street analysts.

Cree reported after the markets closed Tuesday that its revenue rose 35 percent in the fiscal second quarter that ended Dec. 27 compared with a year earlier. Revenue totaled $199.5million; the consensus forecast among analysts was $187 million, according to Thomson Reuters.

Profits totaled $33.8 million, or 32 cents per share, triple its profit of a year ago. Profits excluding stock-based compensation and amortized goodwill was 38 cents per share, versus 30 cents per share projected by analysts.

Cree’s light-emitting diodes, or LEDs, are used to illuminate car dashboards, cell phones, televisions and signs. But the company increasingly is focusing on energy-efficient interior and exterior lighting - it makes its own light fixtures and bulbs and supplies LEDs to lighting companies - and that small-but-rapidly-expanding market drove the company’s sales growth, CEO Chuck Swoboda told analysts during a conference call.

Swoboda hailed Walmart’s agreement to purchase Cree’s LED bulbs for track lighting at 650 stores, a deal that was announced in November, as a milestone.

“We believe this announcement validates that LED lighting is ready for mainstream commercial applications,” he said.

Earlier Tuesday, Cree shares rose 23 cents to close at $54.24. That was down from the company’s 52-week-high of $59.41, recorded last week. But its shares rose above that mark in after-hours trading.

Last year, Cree shares rose 255 percent - more than any other major publicly traded company in the Triangle.

However, Cree shares have risen so high that in recent weeks some analysts have been downgrading the stock even as they raise their estimates for the company’s performance.

“It has a pretty hefty valuation,” said Kumar.

Even so, a dozen analysts rate Cree a buy, and 10 rate it a hold, according to Bloomberg News. Just three recommend selling the shares.
