osram ostar automotive headlamp pro
DESCRIPTION
igh performance Vertical Thin Film with Vias (VTFV) dies in a new and more efficient packaging for harsh environment. The LE UW U1A4, that belongs to OSTAR Headlamp Pro family, shows a breakdown voltage of 13.3V for a current of 1A (at 85°C) and delivers up to 1000 lumens at 5600K in a “20mm x 20mm” package. These performance are obtained due to a complex packaging and assembly process, completely described in this report. Compared with the first generation of Osram’s packaged LED for exterior automotive headlamps, the new OSTAR Headlamp Pro comes with an enhanced design to increase the corrosion robustness and, for the first time, with a remote ceramic phosphor to increase efficiency. This reverse costing report provides an estimation of the production cost of the LE UW U1A4. It describes the overall manufacturing process and highlights key points of innovation developed by OSRAM.

Reverse costing analysis represents the best cost/price evaluation given the
publically available data, and estimates completed by industry experts.
Given the hypothesis presented in this analysis, the major sources of
correction would lead to a +/- 10% correction on the manufacturing cost (if all
parameters are cumulated).
These results are open for discussion. We can reevaluate this circuit with your
information. Please contact us:
