The latest Optrotronic FIT LED driver range from Osram in Munich uses Infineon’s NLM0011 and NLM0010 dual-mode NFC wireless configuration chips with pulse width modulation (PWM). This allows automated programming of on-dimmable LED lighting systems for reduced number of LED driver variants, simplified LED module selection, end-of-line configuration, and high output control precision.
NFC programming of the LED driver replaces time-consuming resistor-setting techniques via a contactless NFC interface. The integrated constant lumen output (CLO) functions additionally help saving energy by maintaining the luminous flux constant over an extended luminaire lifecycle. The NFC interface solution allows for more cost-efficient, non-dimmable LED driver products.
Operational efficiency is improved by enabling automatic in-line or batch programming in production. It also creates significant flexibility throughout the entire LED value chain and LED luminaire life cycle: Luminaire parameters like lumen output and CLO settings can be programmed during the installation. The Osram Tuner4tronic Smartphone App supports fine-tuning and adaption to the desired lighting requirements.
“The combination of Osram’s market-leading LED driver programming suite and Infineon’s ICs extend all the benefits of Near Field Communication to our entire LED driver range,” said Michael Huelskemper, Head of Product Management EMEA at Osram Digital Systems.
The efficiency of logistics is increased and costs for installation, cabling, and maintenance are reduced. The access to these features is fully controllable by the luminaire manufacturer via the security in the App and the chip.
“Infineon’s innovative NFC-PWM series enable the most cost-effective implementation of NFC programming. The integrated features such as the CLO function and the digital parameter setting help our customers to meet the contemporary LED design requirements. At the same time, they are also providing enhanced flexibility,” said Qi Zhu, Director Business Development Contactless Power and Sensing at Infineon’s Power & Sensor Systems Division.
