Vehicle uses innovative new exterior lighting lamps

6 October 2004 Electronics Technology

Ford Australia's new generation 'Focus Concept' car that was exhibited in Auto China Motor Show 2004 uses innovative exterior lighting lamps based on the latest LED products from Osram Opto Semiconductors.

High-power white LEDs in Osram's Golden Dragon series are implemented in a modern shape of headlights creating cool white light output. The LEDs provide a concentrated light at 20 to 40 lumens from an operating current of 350 mA. Depending on the application and ambient conditions, this white SMT LED will last up to 50 000 hours.

A distinct advantage of the Golden Dragon series is high light output from a small footprint which allowed Ford engineers to implement a front turn indicator lamp in a linear light shape produced by a number of yellow Golden Dragon LEDs. The futuristic rear combination lamp uses both Osram's Golden Dragon and Power Topled devices. These latest generation LEDs allowed Ford designers to realise 3-dimensional lamp design creating the image of technological innovation as well as increasing reliability and efficiency of the entire lighting solution.

An innovative delta shape reverse lamp is based on the White Power Topled creating a smooth white light operating at a relatively low current. The high light output brake light is produced from the Osram Golden Dragon devices in amber colour. The tail and indicator light with the high efficiency Power Topled (40 lm/W) have an even smaller footprint (3,4 x 3 mm) than the Golden Dragon (11,2 x 6,2 mm) and so give designers a lot of flexibility to express their creativity.
