incorporate sensing capabilities too. For example, a mobile phone could be equipped with a flash that - when pointed at a shop display in which every item has been given an electronic price tag - could display the price of these items.
Cree’s latest LED troffers suit many applications
The company’s III-nitride CR Series now delivers up to 130 LPW with a standard efficacy of 100 LPW
LED firms Lextar and Wellypower merge
After the merger of the two LED subsidiaries of AU Optronics (AUO), Lextar will have capital values at US $169 million), Lextar will have capital values at US $169 million
This unification hopefully means Lextar can achieve a more complete and vertically integrated business model and further expand its LED lighting and backlighting product lines and customer base.
These developments will take place under the wing of David Su, who will become Chairman and CEO with Allen Huang acting as president.
Lextar is excited about the expected result of the merger. In the past, the company’s backlighting products were mostly for monitor and TV applications but now will also be used in notebook and smartphone applications.
What’s more, aside from developing mostly on solid-state lighting products such as lamps and board lights, Lextar’s new merger will give the company a line of products that also include T5 tube and CCFL lighting applications along with LED bulbs and fixtures.
Also resulting from the merger is an expanded customer portfolio, which gives Lextar OEM businesses in the US and Japan.
Chairman Su notes that Lextar and Wellypowers’ product lines, system platforms and personnel have already merged to form a competent team that will be even more well-versed in lighting operations and able to improve Lextar’s output value in the market.
With its patented TrueWhite Technology, Cree is launching the CR Series LED architectural high efficacy (HE) troffer with 130 lumens per watt (LPW) and 90 CRI.
Cree is also increasing the efficacy of its standard CR family to 100 lumens per watt.
The firm is also expanding the CR troffer line with the new CR Series High Definition (HD) troffer, featuring over 80 CRI with an enhanced colour spectrum and high R9 values using proprietary colour mixing and tuning technology.
The HD technology delivers higher colour quality than traditional 80 CRI fluorescent troffers.
The new CR Series HD troffer effectively targets applications where a slightly lower quality of light is an acceptable trade-off for a lower initial cost.
Delivering high performance and a low cost per lumen, the Cree CR Series has a ten-year warranty and a lifetime of up to 100,000 hours.
An innovative thermal management system and room-side heat sink enable the LEDs to consistently run cooler, providing significant boosts to lifetime, efficacy and colour consistency.
The new CR Series HE troffer consumes nearly 60 percent less energy than a comparable linear fluorescent 34W T12 system and nearly 50 percent less when compared to an existing 32W T8 system.
“These new troffers deliver a no-compromise alternative to fluorescent lighting,” says Greg Merritt, vice president, lighting at Cree. “This is another example of Cree pushing the performance boundaries to improve energy savings and enable faster payback over a broader range of products to accelerate LED lighting adoption.”
The CR Series troffer family includes three models, the CR14 1 x 4 troffer, CR22 2 x 2 troffer and CR24 2 x 4 troffer, is available in a wide range of
