[0022] The embodiment of the present application provides an LED lamp holder with good heat dissipation effect, which solves the problem that the existing downlight lamp holder is generally embedded in the ceiling. During hot weather, the temperature inside the ceiling is high, which makes the downlight embedded in the ceiling also in a relatively high temperature state.
