The invention is directed to an LED lamp comprising a tubular translucent housing (2), and a linear light engine (3) having a linear heat sink (4, 40) and at least one LED module (5) being arranged on the heat sink (4, 40). The linear light engine (3) is arranged inside and enclosed by the housing (2) such that the linear light engine (3) is distanced from the inner wall of the housing (2) about its circumference in sectional side view, wherein the linear light engine (3) is distanced from the inner wall of the housing (2) by a predefined minimum distance (d) of at least 3mm in a horizontal direction (H) and angles (a, ß, ?, d) of at least +/- 45°, preferably +/- 60°, more preferably +/- 75°, most preferably +/- 90° from the horizontal direction (H) to allow the generation of an air circulation around the linear light engine (3) for enhanced heat transfer from the heat sink (4, 40) to the housing (2) by convection. |
