The present invention relates to a mount unit installation structure of an LED lamp buried in a ceiling, comprising a housing accommodating an LED module inside. The mount unit installation structure according to the present invention comprises a mount combining part and a mount unit. The mount combining part integrally protrudes from the middle of an outer circumference of the housing, and a through-hole is formed to penetrate the inside of housing on the front side. According to the mount combining part, an insertion groove is composed of an inner space where a nut is inserted, by being opened by one side, the thickness of the both sides varies, the through-hole is formed at a center of the insertion groove, and the through-hole is formed eccentrically on the front side of the mount combining part. The mount unit comprises: a fixing piece which is connected to the mount combining part by a screw; a hooking piece which is combined to a fixing plate by the medium of a fixing pin to being rotated; and a torsion spring which has the fixing piece installed on the inner circumference and makes the hooking piece elastically rotate outward. The fixing piece comprises: a pair of plate-shaped fixing combining parts at a predetermined distance, wherein a fixing pin penetrates the upper part of one side; and a plate-shaped fixing part which integrally connects the lower sides of the pair of fixing combining parts and has an insertion hole eccentrically penetrating the width of the fixing piece. The mount unit can be used in a synthetic resin housing, and can be assembled without operating the hooking piece upward when the mount unit is assembled to the mount combining part by a screw. The fixing piece of the mount unit and the mount combining part adhere to each other, and a nut is not separated from the insertion groove by itself and is not rotated in the insertion groove. |
