Smart LED Driver having Smart Microcontroller for Lighting Applications

摘要

A smart driver for controlling an LED. The smart driver is configured with a power input, a control input configured for connection to a light controller, a DC power output configured to power an LED, and a smart microcontroller configured to control the DC power output to the LED in response to input from the light controller. The smart microcontroller is configured to dynamically adjust the control of the DC power output to the LED based on the control standard of a light controller connected to the light controller input. Preferably the smart microcontroller is configured to automatically detect the type of light control standard utilized by the light controller in order to automatically adjust DC power output to the LED in accordance to input of the light controller. The smart microcontroller in some embodiments can be configured remotely to recognize a specified light control standard based on a light controller connect or to be connected to the smart driver. The smart driver can further have an auxiliary DC power device output configured for connection to an auxiliary DC power device, such as a sensor. The smart microcontroller in some embodiments can be configured through the light control standard to dynamically adjust the auxiliary DC output to a sensor. Example sensors include environmental sensors, such as occupancy sensors and ambient light sensors, or internal luminaire sensors for sensing internal conditions of the luminaire, for example for detecting faults in the luminaire.
