具有空气传导表面的灯具
摘要：
本发明涉及一种灯具，该灯具具有一个光源(2)，该所述光源具有具体是LED形式的若干发光元件(3)。该灯具在一个第一侧(re)上具有与该光源(2)相邻的多个第一通道开口(5)，并且在一个第二侧(li)上具有与该光源(2)相邻的多个第二通道开口(7)。这些通道开口(5，7)是针对冷却该光源(2)的空气流来设计的。该灯具还在该第一侧(re)上具有与这些第一通道开口(5)相邻的一个第一导风表面(6)并且在该第二侧(li)上并且在该光源(2)下方具有与这些第二通道开口(7)相邻的一个第二导风表面(8)，其中，这两个导风表面(6，8)的设计方式为使得这两个导风表面形成远离该光源(2)展开的一个空气引入区域(A)。因而，可以用尤其有针对性的方式将空气引导至这些通道开口(5，7)。以此方式，迫使流动穿过这些通道开口(5，7)，并且因此使得能够特别有效地将热量从通道开口(5，7)的表面释放到环境中。
摘要（英）：

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.
