Compact track light

Abstract

The utility model discloses a compact structure's track lamp, including the shell, the top of shell is provided with a plurality of first heat dissipation holes, the sidewall of shell near bottom is provided with a plurality of air inlet, the shell is connected with the fixed base in, the bottom of fixed base is connected with the lamp pearl and the reflector, the reflector surrounds lamp pearl setting, the bottom of fixed base is provided with the vent, the reflector includes the light reflection layer and the heat conduction metal layer of connection in proper order, the light reflection layer is near lamp pearl setting. Through setting up the reflector with heat conduction metal layer, can in time export the heat that lamp pearl emits to avoid the heat accumulation, and the heat is transferred to the air between reflector and shell, and these air will rise and in turn through the vent and first heat dissipation hole and dissipate to the outside environment, thereby forming the gas flow, with the gas flow, the outside air will also enter the shell through the air inlet, realizes the passive heat dissipation.
