Lumileds Introduces Surface Mount LEDs for Automotive Signalling
The firm says its SignalSure modules set new standards for surface mount LED reliability.
Philips Lumileds has introduced its new SignalSure mid-power LEDs for automotive signalling applications.
The new surface mount LED is intended to be the most robust and reliable surface mount LED available to the automotive industry today. The modules have undergone a rigorous Multi Environment Overstress Testing (MEOST) regime that exceeds the testing required by today’s standards for automotive signalling LED sources.
SignalSure is available in red-orange and amber colours. Lumileds says that the MEOST testing for SignalSure goes well beyond datasheet maximums to ensure ongoing reliability and performance. As part of the MEOST testing regime, developed in conjunction with the company’s primary customers, SignalSure LEDs are exposed to extreme heat, humidity, and high levels of sulphur gas.
Philips Lumileds simulated high-voltage jump start and high voltage alternator failure to ensure that the SignalSure LEDs would continue to operate without degradation in performance, quality, and light output.
“Reliability and confidence in a surface mount signalling product has been our design objective for SignalSure from the start,” said Paul Martin, Senior Director for Philips Lumileds’ mid-power automotive LEDs.
“There are certainly other surface mount LEDs in use today, but it was clear that the automotive industry’s needs were not being met. Only SignalSure achieves the automotive industry’s desired level of reliability for a surface mount product. No other automotive SMD product we know of goes through the extreme testing applied to our LEDs and as a result, we are delivering a superior SMD with a wide design margin for signalling applications,” he concluded.
Philips Lumileds expects SignalSure to become the surface mount product of choice for a variety of applications where thin, low profile designs are preferred, including centre stop, side-marker, tail, mirror turn, rear fog, and motorcycle signalling.
