1, introduce the near field communication ( NFC) Now into everyone's digital life, such as transport, security, payment, mobile data exchange and labels, etc. It is SONY and NXP company first develop a short-range wireless communication technology, TI and ST company after do more improvement on the basis of this, make the NFC more widely application in consumer electronics products and cheaper prices. Now it has been applied to outdoor LED driver programming. Basic on radio frequency identification (NFC RFID) Technology, USES the 13. 56 MHZ rf frequency transmission. Within 10 cm distance, two-way transmission speed is 424 kbit/s only. NFC technology will be compatible with more devices, provides more likely for the future of unlimited growth. 2, the working mechanism of NFC device can work in active and passive state. By programming the equipment is mainly working in passive mode, this can save a lot of electricity. Active mode of NFC device, such as a programmer or PC, rf fields to provide all the energy for the communications and passive devices. Below explain how NFC devices to work together. NFC conforms to the European computer manufacturers association ( ECMA) 340 and the European telecommunications standards institute ( ETSI) TS 102 190 V1。 1. 1 and the international organization for standardization ( ISO) / international electrotechnical commission ( IEC) Standardization of the 18092 index, such as the NFC device interface of the radio frequency modulation scheme, encoding, transmission speed and frame format. 3, compared with the other agreement to the following table summarizes the NFC become one of the most popular wireless near-field agreement. 4, with NFC programming utility LED drive power given the drive power of simplified, the cost and reliability of these power NFC as the drive power of programmable technology. Utility power is not the first to use the programming technology of driving power supply company, however, these power pioneered in NFC technology is adopted in waterproof IP67 level power supply, its internal Settings have regular dimmer, DALI dimmer and constant lumen output ( CLO) 。
