A lighting device comprising:
- an envelope,
- a light generating unit,
- a stem arranged to support the light generating unit inside the envelope, and
- a mechanical fastening part arranged to fasten the light generating unit at the stem,
- wherein said light generating unit being arranged to at least partially surround the stem, thereby forming a chimney-like structure,
- wherein the mechanical fastening part comprises at least one protrusion and the light generating unit comprises at least one hole adapted to mate with the at least one protrusion so as to fasten the light generating unit to the mechanical fastening part, and
