Black-base LEDs

The TopLED Black Series with lens from Osram Opto Semiconductors is the first TopLED in a black package that can achieve a typical luminous intensity of 1.9 cd (at 20 mA), which means it is as bright as a comparable LED in a white package but offers higher contrast and fewer reflections. The target applications of the red and yellow LED are displays such as fuel price totem signs or public transport passenger information systems.

The LEDs offer high contrast and good legibility in all lighting conditions. The black package ensures there are hardly any reflections from incident light. Displays equipped with black-body LEDs are therefore discernable even in strong sunlight, with high contrast and distance legibility.

The 60° beam angle has been optimised for display applications, making the LED suitable as a replacement for conventional radial LEDs.
