The company had opened a lighting-module laboratory in northern Taiwan as part of its efforts to set up integration capability for its LED lighting business. Jian stressed LED lighting is his company’s another niche in LED industry after entering LED backlight module production.LED strip light unit only needs to be connected up to a 24VDC power source and comes in a cool white and warm white version. Color changing versions for special lighting effects are also available upon request. Glow-Line LED strip lights benefit from very low power consumption, are highly vibration resistant and offer a very long service life of approximately 50000h (compared to 10000 up to 20000h for fluorescent lights). Light output of the LED strip lights is 2700 Lumens for the warm white and 3200 Lumens for the cold white version.
Cypress has integrated the Power LED series specifications and temperature characteristics into the content library of led high bay light Designer 5.0 software, which supports Cypress's EZ-Color(TM) LED controllers. With other LED controllers, engineers must input specific device binning and temperature performance data. Cypress has introduced the CY3265N-RGB evaluation kit enabling designers to begin simplified system design with XLamp LEDs.

The shipments of notebook-PC panels with LED backlights grew by 63% quarter-on-quarter (QoQ) to 2.1 million in the third quarter from 1.3 million in the previous quarter, according to the related report. Taiwan TFT-LCD panel suppliers AU Optronics Corp. (AUO) and Chi Mei Optoelectronics Corp. (CMO) ranked the world’s third- and sixth-largest, respectively, LED-BLU notebook PC panel makers during the period.
The growth is due to the cost reductions and the launches of new notebook PC models. In the third quarter, the penetration of notebook panels with LED backlights reached a new high of 5.4%, compared with 3.4% in the second quarter. With the increasing popularity of LED-BLU panels triggered by the low-cost and new backlight structures, it’s expected to reach 12.2% penetration rate in the fourth quarter. During the third quarter, 12.1-, 13.3- and 15.4-inch were the leading sizes of LED backlight notebook panels. It is expected that new 16:9 panels will largely adopt LED backlights in 2009.
In addition, as notebook-PC brands including led flood light, Dell and Acer are planning to launch many new LED notebook models in the first half of 2009, it is expected that the penetration rate of LED-BLU notebook panels will exceed 25% in the second quarter of 2009.

LED technology] reduces maintenance costs
Phil Dewsbury, product line director for AnalogicTech, said "As engineers add new functionality to entry-level cell phones and other portable systems, they often integrate larger displays into their designs. By providing the required compliance voltage to forward bias the LED high bay lighting as well as a means to control and set the desired current for both common anode and common cathode configurations with 4 LEDs, these new additions to our extensive LED driver product portfolio offer portable system designers improved design flexibility, high power efficiency, lower component count, and multiple current control options in a space-saving package."
As part of the program, nine LEDway streetlights replaced older, less efficient fixtures in downtown Raleigh. The installation is another step in Raleigh’s “LED City” initiative, a joint government/industry effort to evaluate, deploy and promote municipal LED lighting technology. Raleigh Mayor Charles Meeker said “I am very excited that Progress Energy is moving forward with LED streetlights.” He noted this is good for everyone –LED technology] reduces maintenance costs, it reduces energy usage, it produces clearer light.”
The test program allows Progress Energy, the city of Raleigh and industry partners to test LED street lighting in a realistic environment subject to the actual daily conditions under which these lights typically operate.LEDway luminaires use 40 to 60 percent less energy than traditional streetlight sources such as high-pressure sodium (HPS).180W led flood lights also offers more than 100,000 hours of delivered lumens, extending the life of the fixture to more than 23 years – four times longer than HPS with no maintenance costs.
