Würth Elektronik presents its ICLED Color Calculator
Würth Elektronik presents ICLED Color Calculator – a new service on its REDEXPERT online platform. This unique, free tool allows developers to quickly and accurately determine the exact PWM values needed to achieve specific ICLED color values, without requiring additional measurements. Würth Elektronik determines these parameters for each batch before it leaves the warehouse. The advantage: accurate color rendering without additional effort. This expands the options for ICLED lighting and signaling solutions and accelerates their development.
The REDEXPERT ICLED Color Calculator features an intuitive user interface, allowing users to select the desired ICLED type, batch, as well as color and brightness in the CIE 1931 standard color system (“xy color space”). The tool then automatically generates the appropriate digital signals for pulse width modulation (PWM) of the RGB LEDs within the ICLED component. These values can be directly adopted in the programming. This is possible thanks to the meticulous sorting process during ICLED production. Würth Elektronik only offers LEDs with consistent color temperature and brightness properties for each batch. The precision of quality control and binning enables the company to open up new options for advanced LED applications using its innovative development tool.
Design options in light
“The ICLED Color Calculator is the first tool of its kind and further strengthens our position as a service leader. No other manufacturer offers a comparable solution that supports customers all the way through to the production phase,” stresses Alexander Gerfer, CTO at Würth Elektronik eiSos. Carlos Roberto Hernandez Gomez, Product Manager for ICLEDs at Würth Elektronik eiSos, adds: “This tool significantly reduces workload by eliminating the need for manually testing the color combinations. Developers can now select from over 16 million color options and immediately generate the appropriate signal.”
