Lighting device

A lighting device comprising:

• a light source, which comprises at least one light-emitting diode chip and generates light during operation;
• a first optical element, which collimates the transmitted light of the light source in a predefinable angular range;
• a second optical element, which reflects back to the light source light of the light source which at least initially does not enter into the first optical element;
• a third optical element, which reduces the spectral bandwidth of transmitted light of the light source at least in places,
• wherein:
• the first optical element has a light entrance side facing the light source,
• at least part of the light of the light source enters into the first optical element at the light entrance side,
• the second optical element laterally completely surrounds the light entrance side of the first optical element,
• at least a large part of the light of the light source which does not enter into the first optical element impinges on the second optical element,
• the third optical element is arranged at a light exit side of the first optical element facing away from the light entrance side,
• at least a large part of the light emerging from the light exit side of the first optical element passes through the third optical element, and
• the third optical element narrows the spectrum of the transmitted light of the light source at least in places to form a peak having a spectral bandwidth of at most 20 nm.
