Document Type and Number:

WIPO Patent Application WO/2015/008920

Kind Code:

A1

Abstract:

Disclosed is a track lighting device for freely adjusting the color of light emitted to the outside or the light distribution effect using various accessories replaceably installed in front of a light source, and for inducing an inflow of outer air by means of a flow space, which is formed along the entire edge of a heat sink, and an inclined surface at the back of a cooling fin and simultaneously increasing the flow velocity, thereby further improving the cooling performance of the lighting device. The above-mentioned track lighting device comprises: a case (30) electrically connected to a track adapter (20) and provided with a rotation hinge (34) installed to be rotatable in the horizontal direction; a heat sink (40) installed to be rotatable in the vertical direction with regard to the rotation hinge (34) and provided with a cooling fin (44) for heat radiation; a housing (50) for forming a flow space between the housing (50) and the heat sink (40), the housing (50) having a slot (52) for pivoting about a vertical axis with regard to the rotation hinge (34); a light source module (60) installed on the heat sink (40); a diffusion plate (62) fixed to the front surface of the light source module (60); and a reflector (80) releasably assembled to the housing (50).
