The invention relates to a lamp base comprising a plastic base part (320) that is provided with electric connections (61, 62, 63) for supplying power to at least one luminous means (21, 22) of the lamp that is surrounded by the lamp vessel (10). The electric connections (61, 62, 63) comprise contact sections (610, 620, 630) for connecting to power supply lines (51, 52, 53) of the at least one luminous means (21, 22), that protrude from the lamp vessel (10), and the lamp base is equipped with a sealing element (330) for covering the contact sections (610, 620, 630), said sealing element being fixed to the plastic base part (320) by a detent connection (3213, 3223, 3311, 3312, 3321, 3322). Said detent connection is preferably concealed. Said lamp base can be used, for example, in a motor vehicle headlight.
A lamp base having a plastic base part that is provided with electrical connections for supplying power to at least one luminous means, surrounded by a lamp vessel, of the lamp, the electrical connections having contact portions that are provided for connection to supply leads, projecting from the lamp vessel, of the at least one luminous means, and the lamp base being equipped with a closure element for covering the contact portions wherein the closure element is fixed on the plastic base part by a detent connection as a result of which an undisconnectable detent closure is produced between the plastic part and the closure element.
