The invention relates to an internally-embedded turnable lamp holder. The internally-embedded turnable lamp holder comprises a support used for assembling a lamp and vertical plates which are arrangedon two longitudinal sides of the support; a hinge is arranged on a horizontal first side of the support and is used for fixing the lamp holder on an inner top plate of a vehicle; the lower edges of the vertical plates are matched with the shape of the part, in the lamp strip zone, of the inner top plate of the vehicle; and damping rubber strips are arranged on the lower edges of the vertical plates. The support of the lamp holder is applicable to assembly of various lamps; the lamp does not need to be redesigned and developed according to internal decoration styles; a current lamp can be arranged on the support of the lamp holder directly or by additionally arranging a hoisting plate; the applicability of the lamp holder is improved; the development cycle of products is shortened; the development cost is lowered; and the problem that a complicated internal decoration style cannot be connected to an ordinary lamp is well solved by the lamp holder.
