A lamp has a plurality of LEDs which are arranged behind one another in the lamp's longitudinal direction and in LED spacing by means of an LED carrier. Each LED emits light in a certain solid angle area around a beam centre direction. The solid angle area is directed towards a lamp reflector for indirect light emission of the lamp. The number of LEDs and / or the LED spacing is selected in such a way that the solid angle areas of all LEDs after reflection at the light reflector overlap at least partially at an illumination surface distance from an underside of the lamp of at least 0.2 to 2.5 times the distance between the LEDs that are spaced the farthest apart from each other. In this way there results a lamp in which a multiplicity of corresponding illuminants can be used in a simple manner without glare or at least with greatly reduced glare, in order, for example, to replace fluorescent lamps or the like as the customary illuminants. |
