Claim 0:
1. A floodlight comprising:
a light-emitting diode (LED) array configured to illuminate;
one or more sensors;
one or more thermistors configured to monitor one or more temperatures within the floodlight;
a first heat-transfer subsystem to transfer heat from the LED array to a first housing component containing the LED array;
a second heat-transfer subsystem to transfer heat from one or more power supply units to a second housing component;
a microcontroller configured to:
determine, based on temperature readings from the one or more thermistors, a temperature profile of the floodlight; and
adjust, based on the temperature profile, electrical power supplied by a power supply unit subsystem to maintain:
a first temperature of a first thermal zone at or below a first prescribed temperature threshold, the first thermal zone including a first power supply unit configured to supply electrical power to the LED array; and
a second temperature of a second thermal zone at or below a second prescribed temperature threshold, the second thermal zone including a second power supply unit configured to supply electrical power to the one or more sensors.
