Light bulb supporting stand especially for high-voltage halogen lamp

A light bulb supporting stand especially for use in high-voltage halogen lamp includes an electric connection point, a supporting stand lump, a cap member, and a roughly U-shaped maintaining spring. The supporting stand lump is used to accommodate the socket of a light bulb, and is fabricated from high-temperature resistant material such as ceramic material, figurine or the like. The cap member roughly closes the conduction lead terminal side of the supporting stand lump until the conducting lead is put into the opening. The maintaining spring joins the light bulb socket and its one side is fastened in the supporting stand lump by using an inverse-hook shape snap-in tone sheet while the other side holds the cap member on the supporting stand lump. The cap member is manufactured by plastic with a high temperature resistant thermal plasticity such as PPS or LCP via an extremely accurate injection molding, and has the accommodation room to accommodate at least one part of connection points.
