LED driver supporting parameter setting in DMX512, IP67 and NFC wireless manners

Abstract

The invention discloses an LED driver supporting parameter setting in DMX512, IP67 and NFC wireless manners. The technical key point is as follows: the LED driver comprises a wireless programmer, an LED driver and a computer terminal, wherein the LED driver comprises a shell and a sensing circuit arranged in the shell, a wireless signal of the wireless programmer is in bidirectional communicationwith the sensing circuit in the LED driver, and the computer terminal sends parameter information to the LED driver via the wireless programmer. The communication problem between the circuit in the metal shell and the outside is solved, waterproof sealing is ensured, the problem that the input program is fussy to wire can be solved, the programming can be implemented conveniently and quickly, andthe number of the programming times may not be limited via wireless programming.

Description

technical field [0001] The invention belongs to the field of LED drivers, more specifically, it relates to an LED driver that supports DMX512, IP67 and NFC wireless mode setting parameters. Background technique [0002] LED driver (LED Driver) refers to the power adjustment electronic device that drives LED to emit light or LED module components to work normally. Due to the conduction characteristics of the LED PN junction, it can adapt to a very narrow range of power supply voltage and current fluctuations. A slight deviation may not light the LED or seriously reduce the luminous efficiency, or shorten the service life or even burn the chip. The current power frequency power supply and common battery power supply are not suitable for directly supplying LEDs. LED drivers are electronic components that can drive LEDs to work in the optimal voltage or current state. [0003] Since LED applications are almost in every field of electronic applications, the changes in luminous i...
