NXP Semiconductors says that its LED driver ICs can match the lifetime figures of the LEDs themselves, writes our editor Richard Wilson.

The chipmaker has carried out accelerated lifetime tests on its SSL2101 range of LED drivers.

With LED lighting offering the potential to be ten times more efficient than incandescents, manufacturers are commonly reporting lifetime figures exceeding 50,000 hours. As a result the issue of reliability shifts to the associated devices particularly the LED driver.

"Through our ongoing lifetime test, which has now surpassed 7,000 hours, we've set a new benchmark and proven that NXP's mains LED controller and driver ICs are up to the challenge of supporting extreme long-life lamps," said Jacques le Berre, director of marketing and business development for lighting solutions, NXP Semiconductors.

NXP has been conducting the long-running test of LED driver ICs, running continuously since December 2008.

"As of today, the test has reached 7,000 hours and continues to run, demonstrating that NXP mains LED controller and driver ICs are capable of matching LED lifetimes. The test goes well beyond traditional lifetime testing procedures in the semiconductor industry, which are typically based on 1,000 hours' testing time," said the company.

Ian Bryant is Business Development Manager LED Division at Carclo Technical Plastics. He has worked on and off at Carclo (Formerly Combined Optical Industrial) since leaving school. He has worked through the company from Toolmaking to starting the company on the road of LED optics business some 6-7 years ago, starting with a standard range and more in line with the business of custom optics. In between all this he has worked in engineering and as a works Director for a hydraulics company but kept getting pulled back to the optics industrial. We are able to offer the full solution from idea to parts so have a very good understanding on what is needed. You will see some posts from our design team also under my name.
