Abstract

The invention provides an MR16 compatible LED lamp. The lamp has a power line connectable to the transformer of an existing MR16 installation and having suitable LED electronic control circuitry provided therein spaced apart from the lamp. A releasable clip-set connection in the power line is provided between the lamp and the control circuitry. The lamp has a heat sink suitably configured to fit into an MR16 fixture and the power line extends through the heat sink and through a printed circuit board. The heat sink is made of anodized aluminum. The lamp has a collimator with a lens remote from the printed circuit board and secured in relation to the printed circuit board by a screw-threaded connector extending through the lens. In one embodiment, the heat sink includes a protrusion having a pair of oppositely disposed parallel grooves, transverse to the length of the protrusion to engage between flexibly resilient fingers of a clip in an MR16 fixture. The invention extends to an MR16 lighting installation which includes a power supply connected through a transformer to a power line leading to a light fixture, the power line having suitable LED electronic control circuitry provided therein spaced apart from the fixture.
