[origin: CA1194088A] Electric lamp having a sleeve-shaped cap. An electric lamp having a metal sleeve-shaped cap in the form, in which a metal sleeve is arranged, in which the pin of a lamp envelope is accomodated with clamping fit. The cap has at least three depressions which are distributed around its circumference and which are each secured to the sleeve. The inner diameter of the cap - apart from the depressions - is larger than the outer diameter of the sleeve over the whole length of the cap opposite the sleeve. The light source of this lamp can be aligned in three directions with respect to the cap without the use of cement for securing the cap to the lamp envelope. Fig. 10.
