Abstract: Vehicle light (1), in particular motor vehicle headlight (6), comprising a number of light sources (2), a circuit carrier (3) having a front side (3a) and a rear side (3b), wherein the light sources (2) are arranged on the front side (3a) of the circuit carrier (3), a heat sink (4), wherein the heat sink (4) is attached flatly to the rear side (3b) of the circuit carrier (3), and a fan (5) fastened to the heat sink (4), wherein the heat sink (4) has a base body (4a) for flat contact with the rear side (3b) of the circuit carrier (3), a flange (4b) for receiving the fan (5), and an air duct (4c), wherein the flange (4b) encloses an air inlet opening (4d) opening into the air duct (4c), which is designed to receive an air flow (L) generated by the fan (5), wherein the air duct (4c) extends up to an air outlet opening (4e), wherein the heat sink (4) is formed in one piece from 3D-printed material.

Abstract: A cutting device having a spring that is compressed. After a firing pin retainer has travelled a predetermined path, a locking element is released. The release results in the spring being released, causing the firing pin to be accelerated and at the end to strike a percussion cap, whereby a pyrotechnic charge therein is ignited and thereby a delay element, if provided, is lit. This delay element regulates the delay time. Afterwards, an additional charge is ignited. The gas volume thus generated applies pressure to the cutting element. Above a certain pressure the shear pin shears off, causing the cutting element to be axially accelerated. The cutting element strikes the stop at high speed as a result of the acceleration, and penetrates into same. A connection to be cut, which is guided through an opening in front of the stop, is thereby severed.
