Abrégé

A laser leveling tool comprises at least one laser diode for emitting a laser beam; a micro controller unit for controlling the operation of the laser diode; and a thermal sensor for sensing the internal temperature of the laser leveling tool; wherein the micro controller unit is configured to reduce the operation power of the laser diode when the sensed internal temperature reaches a temperature threshold.
