Osram Opto Semiconductors presents P2W 01, a particularly reliable addition to its familiar Osram Ostar Projection series. This new LED contains four chips which can be controlled in two separate groups. The LED therefore represents an integrated solution which in the event of emergencies offers trouble-free operation in safety-related and security-related applications such as control room monitors.
“The redundant system of the new Osram Ostar Projection is ideal for 24/7 applications. If a chip should ever unexpectedly fail, the second system will continue to operate without any problem at all”, said Wolfgang Schnabel, Product Marketing LED at Osram Opto Semiconductors. Up to now, only the chips in the large Osram Ostar Projection P3W could be controlled separately. This is now also possible with the P2W 01. Osram Opto Semiconductors has developed a compact LED with two self-contained parallel systems with two chips each. The connection design has also been improved, from 2-pad to 3‑pad. This means there are now three connections instead of two. All four chips occupy one pad, the other two pads are each reserved for a group of two. “A new soldering process ensures that the heat produced in the application remains low. The connection between the chip and the package can therefore withstand a lot”, added Schnabel.
