Osram Displix multichip LEDs withstand extreme conditions
The robust LEDs are suited for use in high-contrast displays in outdoor applications
Osram Opto Semiconductors has released Displix black and Displix blackprint multichip LEDs.
The most important target applications for these LEDs are in large-format outdoor displays, for example at rock concerts, at sporting events or for perimeter advertising.
These robust high-contrast high-power LEDs can withstand high humidity levels, wide fluctuations in temperature and even torrential rain.
Depending on specific customer requirements, the high-power Displix black/ blackprint SMT LEDs offer excellent contrast and high brightness or good contrast and very high light intensity
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.
Osram says the Displix black offers excellent contrast even in direct sunlight and also precise colour rendering even after a long operating time. Their brightness values are also impressive. The typical light intensity at the Illuminant D65 white point (at a colour 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.
Both Displix versions come in a 4.5 x 4.5 x 2.1 mm package and contain three chips with typical wavelengths of 625nm (red), 528nm (green) and 470nm (blue). This means that individual LEDs do not have to be combined into an RGB cluster. This reduces the pixel spacing and improves the resolution for the same area.
