发明名称 LIGHTING DEVICE HAVING A LIGHT SOURCE HEAT SINK ARRANGED SEPARATE FROM A DRIVER
摘要 A lighting device (1) comprising a driver (7) arranged at a base (2) of the lighting device (1), a heat sink (14) arranged at a portion (3) of the lighting device (1), separate from the driver (7), a light source (13) mounted to the heat sink (14), and a wire (10) arranged to electrically connect the light source (13) to the driver (7), wherein a portion of the wire (10) extending from the base (2) to the portion of the lighting device (1) is arranged to be exposed to light from the light source (13). The present embodiment is advantageous in that the thermal performance is improved and the lifetime of the lighting device (1) is increased. Further, the exposed wire (10) may be illuminated by the light source (13) and visible from outside the lighting device (1), thereby having the appearance of a filament.
