Abstract: An unloosable and unturnable lamp base system includes a lamp base with a central hole defined by a cylindrical wall provided with vertical slots, a cylindrical socket with a central upper hole for the lamp base to fit therein and with vertical ribs on inner surface to press on the outer surface of the lamp base. The slots of the lamp base provide elasticity to clamp a lamp with proper tightness when the lamp is fitted in the central hole of the base. The slots also function an escape passage for heat produced by the lamp to escape preventing the lamp from breaking caused by inflation by heat, and from loosing or rotating.
