In the case of a ceramic insulator block (1) for halogen lamps, which has a flat duct (2) with a flange (3) on its output side (4), the insulating block (1) is provided on the input side (9) of the flat duct (2) with a recess (10) having a bell-shaped contour. The apex (11) of the recess extends towards the output side (4) of the flat duct (2). The recess has an apex height Hs of </= 40%, an apex radius Rs of </= 20% of the height H of the insulating block (1), and a base radius RB between 140% and 60% of Rs. <IMAGE> |
