Abstract:
    According to the invention, the seal (7) of the glass lamp vessel (1) of an electric lamp is fixed by cement (9) in a lamp cap (2), and has a coating of ZrO2 (8) at the area at which it is surrounded by the cement (9). Although the seal (7) is rigidly anchored in the lamp cap (2), the adherence of the cement (9) to the seal (7) is decreased. Cracking and leakage of the lamp vessel (1) are prevented, while the temperature of the seal (7) during operation is lowered.
