2, insulating lamp holder comprises pedestal and is positioned at the vertical rod that pedestal middle part protrudes upward, vertical rod is against the bottom of metal base panel and is connected and fixed with it, on pedestal, have the fixing hole that holds heating column, heating column inserts in fixing hole through the accommodation hole on metal base, the periphery of pedestal is also provided with the groove for cooperatively interacting with the leg of metal base, leg inserts and is connected to each other in groove fixingly, and the below of pedestal is provided with the container cavity that holds driving power;

3, driving power is positioned at container cavity and is connected with wire;

4, lamp sleeve is outside container cavity, and lampshade is arranged on the panel of metal base.

Further, the vertical rod of described insulating lamp holder is connected and fixed by the panel of bolt and metal base.

Further, described heating column is made up of the high material of thermal conductivity factor.

Further, the material that described thermal conductivity factor is high is metallic copper.

Further, the material that described thermal conductivity factor is high is aluminium.

Further, the material that described thermal conductivity factor is high is aluminium alloy.

Further, described LED assembly and heating column contact-making surface add appropriate thermal grease, form a whole.

Further, described lamp holder is standard lamp head.

Further, lampshade comprised clamping or is threaded with being connected of metal base panel.

LED heating column bulb lamp described in the present patent application, by be provided with the metal guide plume being closely affixed with it below LED assembly, the heat that LED can be produced conducts in time, has effectively extended the service life of LED.
