Abstract:
1. A lamp comprising LEDs arranged one behind the other in a longitudinal direction of the lamp and each LED in LED spacing by means of an LED carrier, wherein each LED emits light in a respective solid angle area around a respective beam center direction, wherein the solid angle area is directed toward a lamp reflector for indirect light emission of the lamp, wherein a number of the LEDs and/or the LED spacing is selected such that the solid angle areas of all the LEDs overlap at least partially after reflection at the lamp reflector at an illumination surface distance from an underside of the lamp of 0.2 to 2.5 times a distance between two of the LEDs that are spaced the farthest from each other, wherein the lamp reflector runs in a straight line in the longitudinal direction of the lamp, wherein the lamp reflector is put together in a direction transverse to the lamp from a number of essentially flat or curved reflector surfaces, wherein the reflector surfaces are connected to one another, wherein the reflector surfaces are tilted relative to one another for establishing an illumination angle common to all of the LEDs, and wherein the LED carrier is arranged outside the reflected solid angle area of each LED.
