Osram Opto Semiconductors GmbH of Regensburg, Germany says that its new LED Information Base is an online tool for selecting LEDs for applications in the automotive, industry, consumer and general illumination sectors. Users can quickly and easily find suitable components and then obtain the specifications in digital form that they need for their design projects, says the firm.

The new online tool eliminates checking and copying down values from LED data sheets, since users can now download technical characteristics directly. The LED Information Base (LIB) online portal includes the complete portfolio of LEDs in the visible wavelength range. “Our database currently contains hundreds of product versions. It is being constantly updated and expanded,” says Martin Moritz, who is in charge of the project.

Until now, technical product information for LEDs has been compiled in data sheets and delivered primarily mostly in pdf format. Product developers have had to make a note of the values and enter them in their own design tools. Characteristics such as changes in parameters as a function of temperature are presented in the data sheets as analog graphs. Product developers have then had to manually note the values in order to enter them into their own design tools.

However, in the LED Information Base, users simply select the appropriate LED, click on the data they need, and receive the raw data as an Excel file for downloading. The data available includes current-dependent and temperature-dependent characteristics, emission characteristics and typical emission spectrums.

Osram Opto Semiconductors says that the LED Information Base provides product developers with access to all the information they need for their design calculations. It is located on the web with data that is easy to download and is regularly updated. All that is needed for password-protected access is online registration with name, company and email address.
