Abstract
The utility model discloses a ceramic lamp-holder of an LED bulb. The ceramic lamp-holder comprises a lamp-holder body which is provided with an installation hole. A plurality of LED substrate fixing holes are formed around the bottom of the installation hole. The outer wall of the lower portion of the lamp-holder body is provided with a plurality of heat dissipating holes. A plurality of heat conduction holes communicated with the heat dissipating holes are formed around the bottom of the installation hole. As the outer wall of the lower portion of the lamp-holder body is provided with the heat dissipating holes, and the heat conduction holes communicated with the heat dissipating holes are formed around the bottom of the installation hole, the heat conduction holes can dissipate heat generated by the LED bulb through the heat dissipating holes, and the ceramic lamp-holder is simple in structure, ensures the heat dissipating effect and lowers the manufacturing cost of the lamp-holder.
