Programmable LED driver with mesh network wireless interface
Abstract:
An LED driver includes a first stage. The first stage converts AC power from an AC power source into a DC power source. The driver also includes a second stage that receives the DC power from the first stage. The driver has a buck converter with a constant current output. The buck converter is managed by a buck converter control chip. The buck converter control chip is controlled by a microprocessor with an associated EEPROM. The EEPROM stores settings for the LED driver can be changed either with a wired GUI port or wirelessly through a Zigbee interface. The microprocessor can select a value of a DC output current according to a value of the analog dimming input signal which has been translated using a predetermined programmable relationship between the input signal and the output current.
