Abstract
The present disclosure is directed to a solution providing active thermal management that has multiple innovations and advantages. In some aspects, the design of the active thermal management (ATM) device is not a threshold clamp and instead, is a non-linear equation that proportionally changes relative to the dimming input. In some aspects, the innovation of the ATM design is how ATM works while the light is being dimmed. The design anticipates overheating by reducing power before the product gets to the maximum temperature threshold. The design also may include an equation that predicts the LED die temperature as a function of product case temperature. The ATM may operate responsive to one or more of a plurality of profile or power curves.
