ABSTRACT:
A lamp lock for assembly of a fluorescent lamp with a lamp fixture is provided. A wafer-like body portion is made of electrically insulating material capable of use in the temperature range experienced by bi-pins of the fluorescent lamp. In use, the body portion is inserted between an axial end of the lamp and an adjacent face of the lamp fixture. The body portion has a leading edge and is provided with a slot extending through the leading edge for reception of the bi-pins. The lock further has a first lateral edge for sliding proximal engagement with a planar surface proximate to the lamp fixture for preventing the lock and the lamp from rotating, thereby securing the lamp to the lamp fixture. Preferably, the slot extends between, and in parallel alignment with, the first lateral edge and a second lateral edge of the body portion, such that the distance between the first lateral edge and the slot is greater than the distance between the second lateral edge and the slot. In this way, the lock may be used with at least two types or sizes of lamp fixtures, each of which having different spacing between the lamp holder surface and the bi-pins.
