OSRAM Opto Semiconductors introduces new TOPLED Compact for LCD-Backlighting
With the TOPLED Compact 5630 OSRAM Opto Semiconductors announced a truly innovative addition to the world of LED lighting. By adapting the successful TOPLED packaging technology to the special needs of backlighting applications, OSRAM Opto Semiconductors has created a brilliant LED that will enhance PC screens and flat screens of all sizes. Two new versions of the LED with different coverage of the color space according to the sRGB standard are available to meet various customer requirements.
The ultra-white version of the new TOPLED has an efficiency of 76 lm/W at an operating current of 120 mA. Color space coverage is up to 100% sRGB, depending on the color filters used in the display.
A specially optimized phosphor is used as conversion material to ensure high stability of the color location over time and across a wide temperature range. The multi-white version achieves 67 lm/W for the same operating current and covers up to an impressive 120% of the sRGB color space. Both versions, measuring just 5.6 x 3 x 0.9 mm, offer uniformly high quality in the product and in the application.

“Televisions backlit by LEDs offer brilliant colors and high contrast. The TOPLED Compact provides superb color space coverage, and its high color location stability ensures that colors remain consistent irrespective of the number of hours of operation and other operating conditions, said Winfried Schwedler, Marketing Manager Consumers at OSRAM Opto Semiconductors. “The multi-white TOPLED in particular exhibits a linear response that sets new standards.”

The ultra-white version offers 13% higher efficiency, which means that fewer light sources are required for screen backlighting units to achieve comparable brightness when using these new LEDs. Both LEDs make it easy for monitor and TV manufacturers to meet the strict energy consumption standards such as Energy Star 2010/2012 and EuP Class A 2010/2012.

The new LEDs are flat encapsulated, have no integrated lens and are ideal for side injection into light guides. The tried and tested TOPLED stands for reliability and can be manufactured in large volumes. The TOPLED Compact 5630 is the second LED of this type together with the TOPLED Compact 4520.
