Samsung Electronics Co Ltd of Seoul, Korea has launched Fx-CSP - a line-up of LED packages featuring chip-scale packaging (CSP) and flexible circuit board technology - for use in automotive lighting applications.
"Our new Fx-CSP line-up will bring greater design flexibility and cost competitiveness to the automotive lighting industry," claims Jacob Tarn, executive VP, LED business team, at Samsung Electronics. "We will continue to introduce innovative LED products and technologies, such as multi-chip array technology, that can play a key role in the growth of the automotive LED lighting industry," he adds.
The combination of chip-scale packaging and flexible circuit board technology together enables more compact chip sizing and a higher degree of reliability, says the firm. The use of a flexible circuit board also enables greater heat dissipation, which leads to lower resistance and brings about a greater degree of lumen-per-watt efficiency than using a ceramic board.
In addition, the new automotive LED line-up allows car designers to use a variety of chip arrangements such as a single chip, a 1x4, or a 2x6 multi-chip arrangement to suit different lighting configurations, says Samsung. The Fx-CSP line-up can be used in automotive lighting applications that include position lamps and daytime running lamps (DRLs) as well as headlamps that require higher luminous flux and reliability than other automotive lamps.
The Fx-CSP line-up consists of the single packages Fx1M (1W, for DRLs and position lamps) and Fx1L (3W, for DRLs) as well as the high-voltage array packages Fx4 (14W, for headlamps and light-guide-type DRLs) and Fx2x6 (40W, for multi-beam headlamps). The variation in wattage levels allows Samsung LED lighting packages to work with a wide range of exterior automotive lighting.
Samsung says that, by adding the new Fx-CSP line-up to its existing mid-power and high-power automotive LED component line-ups, it now provides a family of automotive lighting components. Also, the new Fx-CSP LED line-up was recently selected by a major global automotive manufacturer for a compact car headlamp project, notes Samsung.
The firm plans to introduce more CSP technology-based LED components for automotive lighting later this year.
