LED for automotive headlights now available with two chips

The Oslon Black Flat LED series from Osram is now also available on the market as a 2-chip variant. As with other LEDs from the Oslon Black family, the new version is suitable for all headlight functions. In contrast to earlier versions, the new LED, can be attached directly to the PCB since it is an SMT component. Thus, it can then be processed further with other components as part of a standard soldering process. This translates into cost and time savings.

Thanks to UX:3 chip technology, the new Oslon Black Flat features a very light output even with high currents, achieving over 500 lumens at 1 A. The high brightness level of the new LED is emitted from a compact package with dimensions of just 3.1 mm x 3.75 mm and a height of 0.5 mm. The 2-chip LED is suitable for headlight functions, primarily for daylight running light with light guides, as well as generally for low beam and high beam light.

Further benefits of the Oslon Black Flat are a homogeneous distribution of light, high contrast ratio and cyclic stability.
The black QFN (Quad Flat No Leads) housing expands in a similar manner to the circuit board during high temperature cycle loads. As a result, soldered joints are stronger and exposed to less strain.
 A special sealing technology together with the sophisticated package and ceramic converter enable the highly uniform distribution of light as well as good contrast conditions on roads: Chip encapsulation is directly in the package to achieve a defined bright/dark border in the light beam, and the high contrast of the luminous surface of both chips in relation to the package also contributes to this.

Samples of the Oslon Black Flat are available now; volume start-up is planned for the turn of the year.
