Abstract (en)
[origin: WO2014086770A1] The invention relates to a lamp, which has a light source (2) having several light-emitting elements (3), in particular in the form of LEDs. The lamp has first passage openings (5) on a first side (re) next to the light source (2) and second passage openings (7) on a second side (li) next to the light source. The passage openings (5, 7) are designed for an air flow for cooling the light source (2). The lamp also has a first air-conducting surface (6) on the first side (re) next to the first passage openings (5) and below the light source (2) and a second air-conducting surface (8) on the second side (li) next to the second passage openings (7) and below the light source (2), wherein the two air-conducting surfaces (6, 8) are designed in such a way that the two air-conducting surfaces form an air incidence region (A) that expands away from the light source (2). Thus, air can be directed to the passage openings (5, 7) in a particularly targeted manner. In this way, flow through the passage openings (5, 7) is forced and thus especially effective heat discharge from the surfaces of the passages openings (5, 7) to the environment is enabled.
