The new Advanced Power TOPLED Plus from OSRAM Opto Semiconductors provides 15% more light for direct display backlighting than standard Advanced Power TOPLEDs, the company announced recently. Depending on the display, the LEDs in the usual combination of red (623 nm), green (527 nm) and blue (457 nm) cover more than 125% of the NTSC color gamut and are suitable for all directly backlit displays, particularly for large format LCDs in sizes of 24 inches diagonal and up. This new generation of Advanced Power TOPLED Plus offers an optimized display brightness-to-thickness ratio so that the minimum number of LEDs is required.

The improved brightness of the new Advanced Power TOPLED Plus is made possible by a new lens specially designed for backlighting. At an operating current of 100 mA, the LEDs achieve 14 lm (red), 24 lm (green) and 28 mW/sr (blue). The wider viewing angle of the new lens ensures absolutely uniform backlighting. The chips used are 500 µm in size and are fabricated with the latest ThinGaN or Thinfilm technology for the highest efficiency in their class: 65 lm/W (red), 59 lm/W (green) and 27% overall efficiency (blue). With a lifetime of more than 50,000 hours, the Advanced Power TOPLED Plus provides compatibility with typical LCD lifespans.
