Multichip LEDs for outdoor displays
28 November 2012
Opto-Electronics
Large-format outdoor displays, for example at rock concerts, at sporting events or for perimeter advertising, are the main target applications for the new Displix black and Displix blackprint multichip LEDs from Osram Opto Semiconductors. These robust, high-contrast, high-power LEDs can withstand high humidity levels, wide fluctuations in temperature and even torrential rain.
The 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 colour rendering even after a long operating time.
Typical light intensity at the Illuminant D65 white point (at a colour temperature of 6504 Kelvin), is 1450 mcd at an operating current of 20 mA, 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.
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). This means that individual LEDs do not have to be combined into an RGB cluster, which reduces the pixel spacing and improves the resolution for the same area.
Thanks to SMT technology, the LEDs can be easily processed. With a height of 2,1 mm there is enough space for further standard processes such as silicon encapsulation for added protection against harsh outdoor conditions. Special shading elements can also be easily fitted.
Both measures extend the life of the LED, which may be more than 100 000 hours depending on the ambient temperature. At the same time they provide the basis for long-term stability, as evidenced by the approval of the components for various harsh ambient conditions such as specialty corrosive gases, ageing in direct sunlight and resistance to heavy rain.
