Cree Announces LED Downlights and New Linear SSL Fixture

No Comments

Cree has added two new LED downlights and a new linear fixture to its portfolio, and has announced a new SSL module and an extension to its TEMPO testing service.

Leading into Lightfair, Cree made announcements in both its lighting division and its core LED business. Cree Lighting announced a high-end LED downlight that it says targets architectural-grade applications, and a mainstream downlight meant to match the price of compact-fluorescent (CFL)-based downlights. In addition, the company launched the CS series linear solid-state lighting (SSL) fixture rated for 75,000 hours of life. Cree’s LED unit, meanwhile, has announced new LED modules and more comprehensive TEMPO testing services for its LED customers.

The new SR Series Architectural Downlight is available in a choice of 3000K, 3500K and 4000K CCTs with a CRI greater than 90. Cree joins a number of companies in using the word architectural to imply a higher-performing product, although that terminology can be confusing given that it’s more widely used to describe outdoor lighting of buildings and structures.

David Elien, vice president at Cree Lighting, says the optical design of the SR products sets it apart. He said, “Many LED downlights have a gap between the light source and the reflector in the can.” With the new downlight, Cree announced the Cree Light Source-Reflector Unity Optical system. What that means, according to Elien, is that the light is uniformly and evenly spread across the surface of the optics and the reflector.

“With the SR Series, the high-quality LED light you expect from Cree comes in a package that you would expect from an architectural-grade lighting manufacturer and at a price point consistent with the industry,” said Leah Robinson, lighting designer at Affiliated Engineers, Inc. “Plus, its high efficacy and color consistency allows designers to put more thought into the details of their design and feel confident in the quality of their downlighting solutions.”

The SR Series delivers 2000 lm, efficacy of 80 lm/W, and a lifetime of 75,000 hours. The product is priced in the $200 range and Elien said that’s commensurate with architectural-grade products based on legacy sources. That means, according to Elien, that payback is instant. He said, “The goal is no compromise for the user, but to drive payback.”

Contractor-grade downlight

Cree classifies the second new downlight – the KR Series – as contractor grade, and the product will sell in the $150 range. Like the SR Series, the KR series uses Cree TrueWhite technology that mixes amber and red LEDs to produce a warmer light and higher CRI. Indeed, the KR series delivers better than 90 CRI in 2700K, 3000K and 3500K CCT options.

While the SR series is 0-10V dimmable, the KR series is dimmable via a triac to 5% of full output. Cree said the product is a direct replacement for 13W and 26W CFL downlights while offering 30% energy savings and superior efficacy at 54 lm/W.

The new Cree CS series linear fixtures, meanwhile, build on the successful CR series. The CS series does not include a lens but uses a new reflector design to achieve even distribution of light.

Cree already has a happy customer. “We researched the LED market extensively and only Cree offered a solution that delivered high-quality lighting and easy payback,” said Jason D. Curtis, principal of Cardinal Gibbons High School in Raleigh, NC. “Since the new CS series is designed for 75,000 hours of life, Cardinal Gibbons High School can benefit from ongoing operational savings due to decreased maintenance and lower energy consumption compared to the linear fluorescents we replaced.”

The CS series can be suspended from the ceiling or flush mounted with an optional bracket. The luminaires come in 8- and 4-ft versions. The luminaires deliver efficacy of 120 lm/W and CRI above 90.

Cree module and TEMPO

Moving from finished lighting products to enabling technologies, Cree announced a new module designed to replace metal-halide (MH) lamps, and more extensive testing services in its TEMPO program. The new modules are extensions to the company’s LMH2 family with output ranging from 2000-3000 lm. Cree has added a new lens system that delivers a hemispheric light pattern. The module enables 50-70W SSL replacements for MH lamps in applications such as spot and track lights.

In the testing area, Cree has added to its TEMPO (Thermal Electrical Mechanical Photometric Optical) program announced last fall. The new TEMPO 24 offering includes the testing of luminaires made by Cree’s LED customers to the LM-79 standards. The National Voluntary Laboratory Accreditation Program (NVLAP) has accredited Cree’s service. Overall, the TEMPO program also includes some thermal and electrical evaluations that go well beyond LM-79 requirements.

“In my experience, if I had to select a single document that’s had the greatest impact in selling LED light sources to customers, it would be the Cree TEMPO report,” said Pierre van Helden, CEO of LED Lighting SA. “The service provided an independent and thorough review for our products and the results give us the confidence to sell our products with passion—giving our customers the assurance that our products are being designed and produced to the highest international standards.”

LED Financial News: Philips, Cree, LED lighting in Asia Pacific

No Comments

Cree and Royal Philips Electronics have both reported positive quarterly results, while a new report from Pike Research expects LED lighting in the Asia Pacific region to accelerate rapidly after 2015.
Philips Lighting gets first quarter bounce.

Royal Philips Electronics (PHIA.AE) has reported that it delivered a healthy first-quarter 2012 net profit, which was helped by strong sales and gains from asset sales. Philips’ largest division, its healthcare operations, performed strongly, and the lighting division enjoyed its first increase in revenues in eight quarters.

“I’m happy to report that we are now seeing solid improvement across all sectors of our business and our growth figures for the first quarter confirm this trend, with Healthcare growing at 9%, Consumer Lifestyle growth businesses above 7%, and Lighting at 2%. Excluding external sales of Lumileds, which saw a double-digit decline in the quarter due to inventory correction in the channel and an increasing mix of internal sales, our Lighting business actually grew by 4% in the quarter. LED product sales for the quarter grew by 22%, said van Houten.

After taking the helm at Philips a year ago, van Houten aims to make the company leaner and more customer focused. He cautioned, however, about the remainder of 2012, citing the uncertainties in Europe, particularly in the healthcare sector and in construction markets.

The company delivered a net profit of EUR248 million (US326 million) for the first three months of the year, up more than 80% from EUR137 million (US180 million) in the same period last year. In the final quarter of 2011 it had posted a net loss of EUR162 million (US213 million), due to weak markets and losses from its TV business.

In efforts to stem its losses, Philips plans to cut 4500 jobs globally including 1400 positions in the Netherlands.

Cree Reports 30% year-over-year revenue increase

Cree (NASDAQ: CREE) based in Durham, NC has announced revenue of $284.8 million for its third quarter of fiscal 2012 ended March 25, 2012. This represents a 30% increase compared to revenue of $219.2 million reported for the third quarter of fiscal 2011 but a 6% decrease compared to the second quarter of fiscal 2012.

Net income (generally accepted accounting practices or GAAP) for the third quarter was $9.5 million, or $0.08 per diluted share, a decrease of 50% year-over-year compared to GAAP net income of $18.9 million, or $0.17 per diluted share, for the third quarter of fiscal 2011.

“Our third quarter earnings per share were in the middle of our target range as strong factory execution and a tax benefit offset the impact of revenue being slightly below our target range,” stated Chuck Swoboda, Cree chairman and CEO. “Overall company backlog is stronger than it was at this point last quarter, with Lighting, LEDs and Power and RF all tracking ahead of Q2, although order visibility is still limited. Our focus remains on driving adoption through innovation and we believe we are well positioned to continue leading the transition to LED lighting and drive growth in our business.”

For its fourth quarter of fiscal 2012 ending June 24, 2012, Cree targets revenue in a range of $295 million to $315 million with GAAP gross margin targeted to be 35%, which includes a stock-based compensation expense of approximately $2.5 million.

Pike Research expects LED lighting to take off in Asia Pacific

A recently published report from market research company Pike Research based in Boulder, CO states that in most Asia Pacific markets, governments are committing large amounts of funding to basic LED lighting infrastructure, creating an abundance of business opportunities. The firm expects sales of LED lighting systems to increase rapidly over the next ten years and to accelerate sharply after 2015. Unit shipments, including lamps and luminaires, will rise from 66 million in 2011 to 542 million in 2021 — an increase of more than 700%.

Among the frontrunners in energy-efficient lighting technology are Japan, which revealed its plans to lead the LED lighting industry through its 21st Century Light Project more than a decade ago, and Taiwan, which has established a Next Generation Light Source Technology Development & Supply Strategy that calls for a greater reliance on LED lighting and material production as a national industry, reducing its focus on the semiconductor industry.

The report, “Energy Efficient Lighting in Asia Pacific,” describes the key technology and market trends driving the use of LED and other high-efficiency lighting in the commercial, industrial and outdoor stationary sectors within the Asia Pacific region. The report analyzes policy issues, market adoption trends and the competitive landscape.

Why Choose LED Bulbs as The Better Options for Energy Saving Light Bulbs?

No Comments

Individuals are actually now starting to witness the benefit of environmental sustainability in upholding our planet for upcoming future generations. The low-energy consuming light bulb can play a major part and of course the new LED bulbs would have to confirm this. But are they as remarkable as the advertising say and are they essentially worth the purchase? Within this compact and to the point write-up I shall give an insight into the technology of LED Light sources and also deliver details with regards to the energy saving and environmental benefits. This ought to enable you to come up with a better choice in whether or not to go for LED’s.

LED Bulbs and their technological innovation

Light emitting diode technology, consisting of semi-conductors and has been around ever since the early 1960’s, is used for LED’s. The technology for these lighting allows smaller units, in most cases of 1 square millimeter, to be produced and in a spectrum of colors. Also LED’s are specifically very dependable and can resist knocks and bangs while expanding their elegance. The power restriction of the fast units meant that utilization was resulting from applications, as an illustration, electronic unit screens, but the technological progress basically shows potentially they are now used in universal lighting applications.

Energy saving aspects.

If we obtain a 25 watt halogen downlighter as being a comparator then roughly the same level of light output can be purchased from a 3W LED MR16. Applying this example, anybody can enjoy an electrical power saving of about 80% over choosing older-type halogen lamps. The energy saving will drastically reduce electricity costs but furthermore the reduced loading on the electrical wiring system indicates that, in places where transformers are being used they will be using smaller load and are more unlikely to go wrong.

Price facts of LED lights

The value of LED’s is significantly more than possibly the incandescent, halogen or CFL bulbs, but with developments in technology then the selling price now means they are an economical price. The other significant consideration when viewing the cost savings is that usually LED lamps will last about 30000 hours which is 20-30 times lengthier time than an older-type lighting.

A very good technique to compute the savings of utilizing LED bulbs is to consider the cost of buying and running a LED lighting until it fails and comparing this to price of buying and running of equal traditional bulbs. Using this evaluation then the lifespan cost saving works best to be between $100 and $300 a lamp.

The result on your carbon footprint of employing LED bulbs.

The environmental attributes of employing LED’s are 3 fold:

1. LED lamps get an exceptionally longevity compared to regular bulbs and on those grounds the level of landfill is cut down tremendously.

2. When electricity is generated using oil and coal stations then it makes vast amounts of carbon dioxide. The less power consumption results in a large cut in your carbon footprint.

3. LED’s unlike CFL’s do not have mercury or any other dangerous substances which are damaging to the environment.

These types of 3 eco rewards offer transparent facts as to why LED bulbs are the desired option when compared to halogen or certainly CFL technology for low-energy consuming lamps. Eventually these benefits mean that it is predicted that LED technology usually takes over as the major choice.

Energy Saving LED Light Bulbs

No Comments

If you accept been alive on authoritative your home energy-efficient, you accept apparently replaced best of your old beaming ablaze bulbs with energy-saving ablaze led bulbs. Until afresh this was advised a big footfall forward. Those coiled CFL (Compact fluorescent) bulbs sprout from lampshades all over the home and we anticipate we are accomplishing our bit for the environment. But now that led lights has become so abundant added versatile, it is replacing the CFL bulbs and assuming them up as not absolutely as blooming as we had thought.

The crisis of the CFL energy-saving ablaze bulbs has been abundant talked of recently. They accommodate mercury which is actual poisonous. Because they are fragile, breakages appear easily. A lamp aloof has to be agitated over, agape by a cat or a child, and the ball breaks, advertisement the ancestors to this baneful substance, as able-bodied as to shards of burst glass. Disposing of the acclimated ablaze bulbs is additionally ambiguous and if they are not appropriately recycled can be acutely adverse to the environment.

Although CFL bulbs are appreciably added energy-efficient than the old beaming bulbs, LED bulbs out-class them both in energy-efficiency and life-span. LED lights are 30-50% added able than CFLs and their lifespan is bristles times best – that is 50,000 hours as against to beneath than 10,000 hours of the CFLs (and, let’s face it, abounding CFLs accept met with an blow continued afore they accept accomplished their optimum lifespan).

CFLs, admitting actuality answer as a blooming another to beaming bulbs, are not absolutely that acceptable for you. They afford adverse UV radiation and can add to electromagnetic abuse aural the home, causing acute bodies a array of bloom problems.

So why haven’t LED s already taken over from them completely? The problem, as always, is cost. LEDs still bulk added than CFLs to acquirement initially. In the long-term, however, you save considerably, both in your bargain electricity bills and in the bulk adored on replacing acclimated bulbs. Because LEDs are solid and accept no brittle components, they are actual durable, so your advance in one LED ablaze ball could aftermost you for added than ten years. The ball will accept added than paid for itself in two years, so afterwards that for the abutting eight years you are extenuative money all the way. Finally there is a blooming energy-efficient lighting band-aid for eco-friendly homes.

Perfect Suggestions to Buy Cheap LED Light Bulbs And Deploy It for The Christmas Season Decorations

No Comments

For this year’s holiday season, you will probably not put up a lot of decorative lights as you used to. The rough times we live in dampen the holiday spirit, and let’s face it, we really need to make practical choices now.

But there’s a method around this. You still wish to put up lighting but not spend too much on electrical bills after the holiday period. Why not experience using the more eco-friendly and also energy-efficient LED lighting? They need not be extravagant. Buy cheap LED light bulbs from your preferred home improvement shop and you would still be happy to join the holiday pleasure while keeping a big chunk of your financial allowance intact.

There are excellent reasons to experiment with LED lights for your holiday design. While they do cost more compared to incandescent in the beginning, the benefits override the initial cost.

First reason is LED lights are more energy-efficient. LED strip lights require as few as 98% of the electricity needed by incandescent light strands to illuminate. Thanks to their unique makeup, LEDs will not consume as much as power as incandescents do. They produce light via a semiconductor chip instead of filaments.

Buy cheap LED light bulbs and you will have assisted to save the world. LED lights are very pleasant to the earth. Their utilization of less energy can help decrease carbon pollutants, and in contrast to fluorescent-based lights, they do not include mercury and give off ultraviolet light rays. A less common but just as powerful environmental advantage is, LED bulbs aid the prevention of light pollution since they don’t distribute light out into the sky and everywhere else.

Because LED lights use power efficiently, very little heat is produced. This makes LEDs stay cool to the touch. While you’re readjusting your decorative lights, your fingers are unlikely to get burned. In addition, there’s less risk that your house will catch fire because the design of the diodes make the circuit less likely to overload.

Decorative LED lights are available for much less during the holiday season. Starting November, you can buy LED holiday lights for as low as $5. For that little a price tag, you can already snag models that carry UL certification and pass the Energy Star standard. Retailers and local governments typically launch promos for LED lights. You bring your old incandescent strands at kiosks and exchange them for new LED lights.

Even the cheap LED light bulbs you buy can last for years and are more durable. Unlike incandescents, LEDs aren’t made with a filament that break or burn out. The lenses fitted onto the bulb to protect the diodes and disperse light more effectively are made of epoxy. This renders the bulbs indestructible. You can drop them or even step on them and the diodes will continue to shine brightly. You can use your LED string lights for many, many holiday seasons.

With LED lights, you might also need more alternatives to get inventive. LED lights can be found in vibrant colors and in a richer selection of patterns and styles. They are presented in different hues without requiring very expensive filters.
