Abstract
A light fixture having a light source, first and second heat sinks with corresponding first and second thermal interfaces having complementary curved surfaces, and a linkage having cams, and springs to create contact pressure between the thermal interfaces when the light fixture is in an operation mode and to permit movement between the thermal interfaces when the light fixture is in an adjustment mode. When the light fixture is in operation mode, the first and second heat sinks work in combination to provide a highly effective heat dissipation system. When the light fixture is in adjustment mode, the separation created permits the light source to move along an adjustment path to change the angular direction of the light emitted and to rotate about a rotational axis, providing a full range of directional lighting orientations.
