Abstract

A light unit comprising: a housing for securing the unit to a fixture, the housing having a central axis and an axial aperture; a socket adapted to receive a lamp, the socket including a connector for connecting the lamp to a power supply; the socket being mounted on a socket mount within a casing, the socket mount including a socket body; wherein one of the housing and casing includes a driving member and the other of the housing and casing includes a rotational actuator engaging the driving member so that the rotational actuator can cause rotation of the driving member relative to the rotational actuator to cause the casing, socket mount, socket and a lamp received in the socket to rotate axially relative to the housing; wherein the socket mount is pivotally connected to the casing by a hinge located circumferentially of the socket mount; a tilt actuator arranged to cause the socket mount to pivot about the hinge from an axial orientation wherein a lamp engaged to the socket is in a retracted position within the aperture to a deployed position wherein the lamp is deployed at least partially through the aperture tilted relative to the axis; and a heat sink extending upwardly away from the socket mount, the heat sink comprising an array of thermally conductive laminar members located in spaced relation and separated by passageways; wherein the one or more thermally conductive laminar members includes an engagement to engage the tilt actuator to enable the socket mount to pivot from the retracted position to a deployed position.
