- This arc K includes an angular range of approximately 180 °.
- a second example of such a circular arc results - with reference to the illustration of Figures 1 to 4 - in a horizontal section through the lamp 2 at the level of the center of the shape of the support member 10 corresponding ball.
- the circular arc includes 360 ° and thus represents a circular line.
- the joint assembly 8 is thus a ball joint with a spherical condyle and a socket, wherein the support member 10 forms the condyle and the recess 13 of the heat sink 6, the joint socket.
