Illumination & Displays

LED with improved readability in high ambient light


The new 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) 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. Target applications include information displays for traffic and public transportation systems and price-changing displays such as fuel price signs.

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, making displays equipped with black-body LEDs razor sharp, even in strong sunlight.

The 60° beam angle of these LEDs has been optimized for display applications, so the light is focused for excellent distance legibility. They are ideal as a replacement for conventional through-hole radial light emitting diodes.
