Abstract
A system for regulating the temperature of a light source positioned within a liner soaked in resin and installed within an underground pipeline. The system measures the temperature of light emitting diodes supported on the light source as the light source is pulled through the liner to cure the resin. The system is configured to automatically stop the curing process and subsequently step down the power level and the rate of travel of the light source each time a designated temperature threshold is reached. Power is indefinity shut down to the light source if a maximum temperature is reached.
