LED lighting design tool provides faster development

LED lighting design tool provides faster development

New tool draws from an extensive library of LEDs, drivers and heat sinks to help create complete lighting systems up to 100,000 lumens, enabling both novice and expert designers to perform real-time comparisons and optimize complex lighting systems for performance, size and cost in minutes, based on the desired lumens.


National Semiconductor has announced the addition of WEBENCH LED Architect to its portfolio of online WEBENCH Designer tools.  To start a design, the designer enters the desired light output (lumens) and adjusts the design with the unique WEBENCH Optimizer 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. 

“We are enabling creative designers to compare a hundred different topologies for a lighting system in a few minutes,” said Phil Gibson, vice president of Technical Sales Tools at National Semiconductor.  “WEBENCH LED Architect frees their imagination, so they can deliver brilliant lighting designs at the lowest possible cost.”

The visual tool is aimed at developing 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 analyzes 350 of the latest LEDs from 12 leading manufacturers, 30 heat sinks, 35 LED drivers, and a library of 21,000 electronic 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.
