Black Series LEDs Improve Readability in High Ambient Light Conditions

The TopLED Black Series with lens from OSRAM Opto Semiconductors is a range of medium-power LEDs mounted in an industry standard package but in matte black material. The black package offers significantly higher contrast with lower reflectivity than comparable white-package devices without compromising overall luminous intensity. The TopLED Black Series is suited for display applications where contrast is key for improved legibility, especially in high ambient light conditions. The TopLED Black Series is believed to be the first TopLED in a black package that can achieve a typical luminous intensity of 1.9 cd (at 20 mA) and is to date the only LED in a black package that provides the same luminous intensity as a comparable LED in a white package. The new TopLED Black Series with lens offers high contrast and good legibility in all lighting conditions. Its black package ensures there is hardly any reflection from incident light.
