Aircraft light, aircraft comprising an aircraft light, and method of assembling an aircraft light

An aircraft light, comprising:

• a light source support board, having a light source side and a back side;
• and
• a light source, arranged on the light source side of the light source support board;
• wherein the light source support board comprises:
• a first metallic layer, the first metallic layer forming conductive traces on the light source side of the light source support board;
• an isolating layer;
• a second metallic layer, wherein the isolating layer is arranged between the first metallic layer and the second metallic layer and isolates the second metallic layer from the first metallic layer;
• and
• a support board core layer;
• wherein a cavity is provided in the support board core layer and extending through the back side of the light source support board;
• wherein the aircraft light further comprises a metallic body having a first lateral extension less than a second lateral extension of the cavity and arranged within the cavity of the light source support board;
• and
• wherein the metallic body has an inner end face, which is soldered to the second metallic layer, and an outer end face, which is substantially flush with the back side of the light source support board.
