A LED lamp holder includes a heat sink made of aluminum or copper by stretching molding and defining opposing recessed top end and hollow bottom end, one or a number of LED chips mounted in the recessed top end of the heat sink and adapted for emitting light, and a light transmissive lampshade fastened to the recessed top end of the heat sink by a hook joint or screw joint, or by means of adhesive bonding. The heat sink can be configured to provide a hollow block in the recessed top end thereof for holding multiple LED chips on multiple peripheral walls thereof. |
