Lamp having air-conducting surfaces and air passage openings

A lamp, comprising:

• a light source with a plurality of light output elements, and a lamp body having first passage openings next to the light source on a first side and second passage openings next to the light source on a second side, the first and the second passage openings being designed for an air flow for cooling the light source,
• wherein the lamp body also having a first air-conducting surface next to the first passage openings on the first side located below the light source and a second air-conducting surface next to the second passage openings on the second side below the light source,
• wherein the two air-conducting surfaces are designed in such a way that they form an air incidence region that expands away from the light source
• wherein the second air-conducting surface is formed by an outer surface of a housing, the housing being configured to mount an operating device of the lamp body, and
• wherein at least one of the first passage openings and the first air-conducting surface are configured as part of a heat sink, in which the housing is connected to the heat sink in a manner held mechanically solely via a screw connection.
