Patent ID: 8079727

Claim:
A recessed lamp support structure, comprising: a lamp holder having a bottom portion formed with an opening, the lamp holder defining therein a receiving space for accommodating and fixing a light-emitting element therein, the lamp holder having a peripheral edge which is adjacent to the opening and extends radially so as to form an annular frame around the bottom portion of the lamp holder; and at least two resilient plates, each said resilient plate made by bending a flexible metal plate so as to form a front section, a middle section, and a rear section, the front sections of the at least two resilient plates being fixedly connected to a sidewall of the lamp holder in a symmetrical manner, the middle section of each said resilient plate extending toward a rim of the annular frame and having a tail end from which a corresponding said rear section extends, wherein a length of the middle section of each said resilient plate allows the sidewall of the lamp holder to pass through a receiving hole formed in a ceiling and be received on a top side of the ceiling such that the rear section of each said resilient plate presses tightly against an inner periphery of the receiving hole while a top side of the annular frame presses against a bottom side of the ceiling, tangent lines of each said resilient plate and the tail end of a corresponding said middle section form an included angle, and the magnitude of each said included angle and a length of the rear section of each said resilient plate allow an outer surface of the rear section of each said resilient plate to press against the inner periphery of the receiving hole.
