摘要

The lamp has a set of LEDs (6) arranged in a bulb housing, where the bulb housing comprises tubular hollow bodies (4). The LEDs are arranged in an edge area of the tubular hollow bodies, where the tubular hollow bodies comprise round, oval, rectangular, quadratic or polygonal cross-sections. An intermediate spacing is arranged between outer surfaces of the tubular hollow bodies. The tubular hollow bodies are made of heat conducting material i.e. metal. The LEDs are arranged on printed circuit boards (7). A ventilator (8) is arranged relative to the LEDs at an end of the bodies.
