Today's smart LED bulbs let users control features including brightness and color. These properties are controlled though the driver and can be programmed and modified at any time during manufacturing, distribution, installation or maintenance.

The use of NFC technology enables wireless programming using a smartphone, tablet or portable NFC reader, without having to power up the LED driver, and brings enhanced flexibility and energy-savings in addition to reducing development time and cost.

STMicroelectronics offers optimized and complete LED driver programming solutions with its comprehensive NFC portfolio, fully addressing the lighting market and featuring all the functions needed for wireless LED programming.
