    Abstract: An LED lighting assembly structure includes a lamp housing, and an end cap. The lamp housing includes at least one slot. The end cap includes a lug cap, at least one through-hole, and at least one reinforcing rib, and at least one fastener. The reinforcing rib and the through-hole are partially coincident with each other in a cross section perpendicular to the central axis of the through-hole. When the fastener is screwed into the through-hole and the slot, it may either cut into the reinforcing rib, or the reinforcing rib is pressed against the lug cap, or both the reinforcing rib is pressed against the lug cap and the fastener cuts into the reinforcing rib. As a result, the strength between the fastener and the lamp frame is improved, and it is possible to make the lamp house smaller and thinner, which is advantageous in reducing the volume of the entire lamp.
