Systems and methods for data communication from an LED device to the driver system

摘要

One or more operating conditions of an LED device is sensed, and the sensed condition is communicated to an LED driver by modulating a load thereof.

1. An LED system comprising:
an LED driver; sensing circuitry for sensing an operating condition affecting an LED device; and communication circuitry for modulating a load of the LED driver based on the sensed operating condition, thereby communicating the sensed condition to the LED driver, wherein the communication circuitry is configured to modulate the load in a temporal pattern corresponding to a digital value that itself corresponds to the sensed operating condition, and the LED driver is configured to alter at least one of a current or a voltage supplied to the LED device based on the modulated driver load in order to optimize performance and lifetime thereof.
