<p>The invention relates to a lamp comprising a body portion (1) and a cover (2) as well as a seal (7) between the body portion and the cover for sealing the cover against the body portion. In order that the service life of the lamp may be long and its operation safe, so that the lamp is tight against humidity also in such operating conditions, when exposed to an external load, such as to a load caused by washing with pressure water, and in order that the lamp may be easy to manufacture, the lamp is characterized in that, between the seal (7) and the body portion (1), there is a chemical bond (8a, 8b, 8c) between the sealing material and the material of the body portion for keeping the seal tightly fastened to the body portion, which chemical bond is provided by casting the seal in a mould together with the body portion, the seal (7) comprises a first continuous sealing face (9) arranged to seal the cover against a first stop face (12), the seal (7) comprises a second continuous sealing face (10) arranged to seal the cover against a second continuous stop face (13) being functionally apart from the first sealing face (9), and the seal comprises a third continuous sealing face (10) arranged to seal the cover against a third stop face (14) and being functionally apart from the first sealing face and the second sealing face. <IMAGE></p> |
