A moving-head device (1) comprises afoot (10) and ahead (20) that is movably arranged with respect to the foot (10). The head (20) comprises a first rotation member (21) that is rotatable with respect to the foot (10) about a first rotation axis (51), and a second rotation member (22) that is rotatable with respect to the first rotation member (21) about a second rotation axis (81). A lamp (61) is arranged inside the first rotation member (21), while directing means (62, 70, 75, 77, 78) are provided for directing light originating from the lamp (61) to an external light outlet (31). If the first rotation axis (51) extends in a vertical portion of the lamp (61) constituting an upper side (64) does not change during operation of the moving-head device (1), so that said portion may be easily cooled continuously.
