Here comes a multichip LED for extreme conditions

BANGALORE, INDIA: Osram Opto Semiconductors recently launched the availability of Osram Displix multichip LEDs for extreme conditions such has large-format outdoor displays, ideally suited for rock concerts, at sporting events or for perimeter advertising.

The new Displix black and Displix blackprint multichip LEDs from Osram Opto Semiconductors comes with robust high-contrast high-power LEDs, which can withstand high humidity levels, wide fluctuations in temperature and even torrential rain, said a company release.

The high-quality multichip LED is available as Displix black in a black package with a black reflector and as Displix blackprint in a white package with black overprinting and white reflector. Displix black offers excellent contrast even in direct sunlight and offers precise color rendering even after a long operating time, says the firm.

The typical light intensity at the Illuminant D65 white point (at a color temperature of 6504 Kelvin), is 1450 millicandela (mcd) at an operating current of 20 milliamps, which appears very bright in the black package. Under the same operating conditions Displix blackprint is even more intense at 2950 mcd with good contrast.

Sven Weber, marketing manager for LED Displays at Osram Opto Semiconductors, said: "People are more and more used to seeing HD images in their homes and on HD compatible devices so the requirements placed on outdoor displays are changing. The two new Displix versions enable long-life displays with high resolution, high intensity and excellent contrast to be produced for a wide variety of applications."

The 4.5 x 4.5 x 2.1 mm package for both Displix versions contains three chips with typical wavelengths of 625 nm (red), 528 nm (green) and 470 nm (blue), which means individual LEDs do not have to be combined into an RGB cluster, the release added.
