The present invention relates to a light emitting diode lamp holder, which includes: a base portion and a light emitting diode base portion. The base portion has a left side and a right side, each of which is extended to form an ear wall. Heat dissipation fins are arranged between the ear walls. Furthermore, a heat exchange guide tube is sandwiched between a bottom of the base portion and the light emitting diode base portion, and the heat exchange guide tube has two ends, each of which is provided with an external terminal extending to outside of the light emitting diode lamp holder.本發明係指一種發光二極體燈座，包含有：基部與發光二極體基部。而該基部左、右上伸有耳牆，該耳牆之間分佈有散熱鰭片，並該基部下方與發光二極體基部之間夾貼有熱交換導管，且該熱交換導管兩端設有伸出發光二極體燈座之外接端子。
