Abstract
A lighting device and a lighting unit comprising a reflector and a lighting device, or LED lamp are described. The LED lamp have a first and a second LED assembly. Each LED assembly comprises at least one LED element with an LED chip and a carrier with a flat surface for carrying the LED chip. The LED chip emits light with a main optical direction. The first and second LED assembly are mounted relative to each other so that at least a first LED element from the first LED assembly and a second LED element from the second LED assembly enclose a rotating angle (γ) between their respective flat surfaces with respect to an axis of rotation (A) so as to involve light angle between the first and second main optical directions. The axis of rotation (A) is parallel to a plane of a flat carrier surface of at least one LED element. The first and second LED assemblies are arranged offset from each other parallel to the axis of rotation (A). Thus, a lighting device with small dimensions and advantageous light distribution is obtained.
