Online LED circuit design tool

29 September 2010 News Opto-Electronics

National Semiconductor has announced the addition of WEBENCH LED Architect to its portfolio of online WEBENCH Designer tools. The new tool enables both novice and expert designers to perform real-time comparisons and optimise complex lighting systems for performance, size and cost in minutes.

To start a design, the designer enters their desired light output (lumens) and adjusts the design with the optimiser dial, evaluating size, conversion efficiency and cost trade-offs. The designer can order components for prototyping, share the complete system with others, or print a complete project report including schematics, bill of materials (BOM) and performance characteristics. A video demonstration can be viewed at http://bit.ly/LEDvideo.

WEBENCH LED Architect is a quick visual tool for complete lighting system design up to 100 000 lumens in output. LED performance, electronic drive current and heat compensation are balanced in seconds. The tool analyses 350 of the latest LEDs from 12 leading manufacturers, 30 heatsinks, 35 LED drivers and a library of 21 000 passive components. Users can focus on system level results and leave the burden of complex electrical and thermal mathematics to the tool. Electrical simulation is included as an option for additional testing, validation or component selection.
