<p>Disclosed is a track lighting device which freely controls the color of light irradiated to the outside or a light distribution effect by using various accessories installed to be replaceable on the front side of a light source, induces the inflow of external air by using a drift space formed along the circumference of a heat sink and an inclined plane of the rear side of a cooling pin as a medium, and improves the velocity of a flow rate at the same time. Therefore, the track lighting device can improve cooling performance of a lighting device more. The track lighting device comprises; a case (30) which is electrically connected to a track adaptor (20) and includes a rotary hinge (34) installed to be able to rotate in a horizontal direction; a heat sink (40) which is installed to be able to rotate in a vertical direction about the rotary hinge (34) and includes a cooling pin (44) for heat radiation; a housing (50) which forms a space apart from the heat sink (40) to include a slot (52) for pivot turn in a vertical direction about the rotary hinge (34); a lighting module (60) installed in the heat sink (40); a diffusion plate (62) fixated on the front side of the lighting module (60); and a reflector (80) which is assembled to the housing (50) detachably.</p> |
