摘要：
An adapter is provided for retrofitting a lighting fixture with a light emitting diode (LED) lamp. The adapter includes a pin plate and a retaining ring. The pin plate includes at least one pin extending outward from a distal side of the pin plate. The retaining ring includes a base, at least one arm, and at least one projecting member, each having inward and outward surfaces. The at least one pin restricts movement of the adapter when the adapter is rotated to a restraining position. The at least one projecting member causes the inward surface of the at least one projecting member to face the inward surface of the base. The at least one projecting member restricts movement of the adapter in a direction corresponding to an axis of rotation of the adapter using the at least one projecting member.
