The present disclosure provides methods, devices, and computer-readable media for health monitoring of lights. One or more embodiments include receiving data, including a junction temperature of a light emitting diode (LED), an ambient temperature, and a drive current associated with the LED, receiving a pre-existing LED performance data set, and determining an end of life of the LED based on the junction temperature of the LED, the ambient temperature, the drive current associated with the LED, and the pre-existing LED performance data set.

Health monitoring of lights

A lamp head is configured to be electrically coupled solely to a power-supply element and a return element. A power voltage carried by the power-supply element is regulated by a control element. The lamp includes at least one LED configured to emit light, and a first circuit coupled to the at least one LED and configured to adjust the brightness of the light emitted by the at least one LED solely in response to adjustments made to the power voltage by the control element.
