CES: Osram’s day in the spotlight

Osram Opto Semi has doubled the power of its top-end multi-coloured stage lighting LED, creating Ostar Stage LE RTDUW S2WP.

“Compared with previous members of the product family, the chips are twice as large as the previous ones but, at 5.7 x 6.4 x 1.3mm, the package size is only slightly larger,” said the firm – up from 4.8 x 5.9 x 1.23mm.

Each of the four die – red, green, blue and white, is 2mm² and can handle up to 4.5A.

Binned at 1.4A, typical output is red=140 lm, green=280 lm, deep blue=1.8W. “If the LED is operated at 4.5A, the brightness per colour increases by factor 2.6″, said Osram.

The white die has a ceramic phosphor, helping to achieve 20,000h lifetime (L50/B50) at 1,000 lm full output.

Stage and exhibition lighting are the intended markets. “Our aim with this new LED is to raise the standard for moving heads in the high-output category,” said product marketing manager Wolfgang Schnabel.

See the LED at the Las Vegas Consumer Electronics Show (CES) next week.
