Abstract

Die Lampe (10) umfasst wenigstens einen Sockel (11) zur Anbindung an eine Leuchte, mit einem gewölbten, im wesentlichen rotationssymmetrischen Reflektor (13), in dessen Brennpunkt (32) oder Brennpunktbereich zur Erzeugung einer gerichteten, z.B. eng abstrahlenden, Lichtverteilung der Lampe (10) eine Lichtquelle angeordnet ist, wobei der Reflektor eine Reflektoröffnung (15) aufweist, die eine Lichtaustrittsebene (E) der Lampe (10) bereitstellt. Die Besonderheit besteht darin, dass die Lichtquelle von wenigstens einer LED (20, 20a, 20b, 20c) gebildet und beabstandet von der Innenseite (14) des Reflektors angeordnet ist, dass wenigstens ein Funktionselement der LED, insbesondere wenigstens eine Spannungsversorgungsleitung (21a, 21b, 21c, 21d) der LED und/oder wenigstens ein Kühlkörper (29, 30a, 30b, 30c, 30d) für die LED, zumindest teilweise im wesentlichen entlang der Lichtaustrittsebene (E) verläuft oder zumindest teilweise auf der dem Reflektor (13) abgewandten Seite der Lichtaustrittsebene (E) angeordnet ist und dass dem Reflektor (13) ein transparentes Deckelelement (17) zugeordnet ist, welches die Reflektoröffnung (15) verschließt.

The lamp (10) comprises at least one base (11) for connection to a luminaire, with a curved, substantially rotationally symmetrical reflector (13), in the focal point (32) or focal point region for generating a directed, eg narrow emission, light distribution of the lamp (10) a light source is arranged, wherein the reflector has a reflector opening (15) which provides a light exit plane (E) of the lamp (10). The special feature consists in that the light source is formed by at least one LED (20, 20a, 20b, 20c) and spaced from the inside (14) of the reflector, that at least one functional element of the LED, in particular at least one voltage supply line (21a, 21b , 21c, 21d) of the LED and / or at least one heat sink (29, 30a, 30b, 30c, 30d) for the LED, at least partially substantially along the light exit plane (E) or at least partially remote from the reflector (13) Side of the light exit plane (E) is arranged and that the reflector (13) is associated with a transparent cover element (17) which closes the reflector opening (15).
