Abstract

The invention relates to an LED lamp (1) having a converter (6) and an arrangement, connected to the converter, of light-emitting diodes (8, 49) arranged on at least one printed circuit board (9). The converter is arranged in a multi-part, latchable housing (20) which completely surrounds the converter and is made of electrically non-conductive material.
