The utility model utilizes lamp socket that its thermal source is reached on the heat-sink unit, and by the through hole on the lid, guiding outer gas stream process heat radiation runner and channel part, thus the thermal source on the heat-sink unit is taken out of, with efficiently radiates heat.
Preferably, the channel part of described lampshade is any of elongated slot or through hole.
Preferably, described heat-sink unit is made by aluminium or any metal material of copper.
Preferably, has the joint portion in the described lampshade.
Preferably, described heat-sink unit has engaging groove, and described engaging groove is corresponding with the joint portion of described lampshade to be cooperated.
Preferably, described heat radiation runner is located on the top periphery of described heat-sink unit.
Preferably, the heat radiation runner of described heat-sink unit is any of indent semicircle, indent rectangle or indent V-arrangement.
Preferably, described lamp socket comprises: circuit board and the illuminator that is arranged on the described circuit board.
Preferably, described illuminator is a light emitting diode.
