Osram Opto launches TOPLED Compact with expanded color space coverage for LCD backlighting

After adapting its TOPLED packaging technology to the special needs of backlighting applications, Osram Opto Semiconductors GmbH of Regensburg, Germany has launched the TOPLED Compact 5630 LED which, the firm says, can enhance monitor and TV screens of all sizes. The 5630 is the second product in the TOPLED Compact family, joining the existing TOPLED Compact 4520.

Two new versions of the 5630 are available with different coverage of the color space (according to the sRGB standard) to meet various requirements.

The ultra-white version has a luminous efficiency of 76lm/W at an operating current of 120mA. 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 white point over time and across a wide temperature range. Also, a multi-white version achieves 67lm/W for the same operating current and covers up to 120% of the sRGB color space. Both versions measure just 5.6mm x 3.0mm x 0.9mm in size and offer uniformly high quality in the product and in the application, says Osram Opto.

“Televisions backlit by LEDs offer brilliant colors and high contrast,” says Winfried Schwedler, marketing manager, Consumer Applications, at Osram Opto. “The TOPLED Compact provides superb color space coverage, and its high white-point stability ensures that colors remain consistent over its operating lifetime,” she adds. “The multi-white TOPLED in particular exhibits a linear response that sets new standards.”

The ultra-white version offers 13% higher efficiency, so fewer LEDs are required for screen backlighting units to achieve comparable brightness.

Osram Opto says that both TOPLED Compact 5630 LEDs make it easy for monitor and TV manufacturers to meet strict energy consumption standards of Energy Star 2010/2012 and EuP Class A 2010/2012.

The new LEDs are flat-encapsulated, have no integrated lens, and provide high efficiency for injection into light guides, says Osram Opto.
