The invention relates to a lighting device (DE) comprising: a printed circuit board (CC) and a first moulding part (PM1). The printed circuit board comprises a first surface (F1), the first surface comprises a first region (Z1) and a second region (Z2), the first region is equipped with first light sources (S1) for generating first photons, and the second region is located behind the first region(Z1) and equipped with second light sources (S2) for generating second photons. The first moulding part (PM1) defines a first cavity (C1) and a second cavity (C2), the first cavity is bounded by a first reflector (R1) in a first rear part (PR1), the first reflector is oriented towards each first source (S1) and reflects the first photons towards the front portion (PV), the second cavity is boundedby a second reflector (R2) in a second rear part (PR2), the second reflector is at least partially offset behind the first reflector (R1) while extending behind the first reflector, and the second reflector is oriented towards the front portion (PV) towards each second light source (S2) and reflects the second photons (R1) passing through the rear part of the first reflector towards the front portion (PV).
