## Abstract

The invention provides a lighting module (100) for use in a luminaire (200). The lighting module (100) comprises: a base (101) having a longitudinal axis (LA) and being constructed for rotatably connecting the base (101) to a socket (119) of a luminaire (200). The lighting module (100) further comprises a carrier (102) connected to the base (101) and extending from the base (101) in the direction of the longitudinal axis (LA). The lighting 5 module (100) further comprises a light unit (103) comprising a light source (104) and a heat sink (105) for dissipating thermal energy of the light source (104). The heat sink (105) extends in the direction of the longitudinal axis (LA) and is positioned at a non-zero distance D1 to the longitudinal axis (LA). The lighting module (100) further comprising a connecting construction (106) connecting the light unit (103) rotatably to the carrier (102) for rotating 10 the light unit (103) both around the carrier (102) and longitudinal axis (LA).
