Car Interior LED Lighting Buckles Up With Tiny SMT LEDs!


Osram has further miniaturised its successful Topled LEDs which are known to set a worldwide standard as the first surface-mountable LED more than 25 years ago. The new generation of Topleds, called Topled E1608, come in a package that is smaller than its predecessor models by factor 20. These robust LEDs are suitable particularly for the automotive sector for applications such as displays, ambient lighting and backlighting of switches and instruments.

The new low-power LEDs combine a smaller package with exceptional versatility to meet an extremely wide range of customer requirements

“Despite this considerable miniaturization the low-power LED is bright, reliable and robust. The compact Topled offers greater options and greater design flexibility, particularly for car interior applications”, says the firm.

The E1608 LEDs are all based on the latest chip technologies including –  ThinGaN, thin film and Sapphire.


With the latest high-efficiency converters, the low-power LEDs produce outstanding values. The firm claims they are 3.6 times brighter than their predecessors at a normal operating current of 20 mA.

The pure green conversion version, for example, achieves the impressive and unprecedented value of 780 mcd at 10 mA. At the same current it is said to be three times brighter than the classic Topled.

In terms of miniaturization, the E1608 boasts a more compact package dimensions of 1.6 mm x 0.8 mm. In contrast, the standard Topled currently measures 3.2 mm x 2.8 mm. At 0.6 mm the height of the E1608 is also considerably less than the previous figure of 1.9 mm.

More compact package dimensions of the E1608 allow it to be used for more compact customer systems.

Commenting about the new LEDs, Anita Wenzl, Manager LED Automotive Interior at Osram Opto Semiconductors, said: “The new Topled E1608 LEDs are some of the smallest LEDs in their class. In addition, they offer reliability, a wide selection of colors and impressive values. Whatever the customer requirements they are suitable whether the application is toward to top or bottom of the brightness range. We are assuming therefore that they will gradually become firmly established and may even define a new industry standard”.

The new Topled generation will be available in numerous colors – from yellow and orange to super red, white, pure green and true green.

The firm has currently launched six Topled E1608 products and further plans to expand the series later in 2017.
