Definitions

  • This invention relates to a lighting unit of the kind used to mount a lamp on a ceiling, wall, panel or other fixture, particularly but not exclusively within a cavity formed in the fixture.
  • a typical application is that the unit may be received within a hole in a suspended ceiling.
  • the lamp may comprise a LED lamp array.
  • Alternative embodiments may comprise halogen bulbs, OLED lamps or incandescent lamps. LED lamps generate a lot of heat during use, particularly over a prolonged period. This creates difficulties in design of lighting units.
  • US 2005/027619A discloses a recessed LED light assembly having a motorised gimbal with pairs of orthogonal bearings to enable rotation of the lamp on two axis.
  • a disadvantage of such an assembly is that the gimbal bearings have a poor capacity for conduction of heat from the lamp.
  • LED "scoop" light fittings are commonly used in retail environments to provide high quality light for display purposes. Such a fitting can be rotated and the lens tilted and to direct light onto an area of special interest, for example a display stand.
  • a significant limitation of current fittings is that when a retail store layout is changed, for example, due to seasonal stock changes, light fittings must be manually adjusted for the new layout.
  • a light unit comprises 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;
  • 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;
  • the 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.
  • Preferred embodiments provide recessed retail fittings that allow for remote control of light direction, light colour and lighting intensity, both for individual fittings and for groups of fittings.
  • Remote control may be afforded using computer software or smart device applications. Commands from the software may be typically communicated to individual light units or groups of light units by wireless communication methods such as Bluetooth or Wi-Fi. However signals may also be sent through the mains power circuit.
  • Such a lighting unit may provide one or more of the following benefits: 1. Easy manipulation of light fittings by staff members from the floor level removes the need for manual adjustment and reduces health and safety considerations;
  • Lighting can be controlled from remote locations, for example by a Head Office; 4. Control of multiple retail or other sites from a single location and the ability to copy and replicate lighting layouts from one location to another; 5. Lighting layouts can be pre-programmed during retail layout design and may be quickly implemented during roll out;
  • the socket body may be part spherical.
  • the part spherical socket body may be arranged to be deployed at least partially through the aperture and tilted relative to the axis when in a deployed position.
  • the socket body may be arranged to extend substantially across the aperture in the retracted position.
  • the socket body may extend radially from the hinge in a direction perpendicular to the hinge axis, the socket body having a peripheral configuration with an outer radial dimension less than the radial dimension of the casing in the direction extending from the hinge axis. This configuration permits rotation of the socket mount and heat sink so that the lamp may pivot out of the aperture to a deployed position without interruption of the light beam by the edge of the housing.
  • the driving member may be a circular ring.
  • a partially circular ring for example a C-shaped member may be provided for use in embodiments in which complete rotation of the unit is not required.
  • the driving member may comprise a toothed rack arranged to engage a toothed pinion of the actuator.
  • the driving member may comprise a friction drive.
  • the actuator and the tilt actuator may be electric motors, for example stepper motors.
  • the driving member may be integral with the casing, the actuator being secured to the housing.
  • the motor only thermally conductively connected to the lamp through the rack and pinion, reducing any risk of thermal damage to the motor. Supply of electric power to the motor is also facilitated.
  • the heat sink may be integral with the socket mount and arranged to conduct heat from the lamp in use, preventing overheating of the lamp and adjacent components.
  • the laminar members and passageways may extend generally vertically to facilitate convection of air in use.
  • 5 to 20 plates or fins typically about 11 plates or fins may be employed.
  • the casing may comprise a shell to form a socket which at least partially encloses the socket mount.
  • the casing may have an inner surface with a spherical configuration, and the socket mount and heat sink having spherical outer surfaces with a smaller radius than the casing inner surface to permit rotation of the socket mount within the casing about the hinge axis.
  • a ball and socket arrangement may be provided.
  • the casing may have an inner surface with a spherical configuration, and the socket body and heat sink may have spherical outer surfaces with smaller radii than the casing inner surface to permit rotation of the socket mount within the casing about the hinge axis.
  • a ball and socket arrangement may be provided.
  • the array of thermally conductive laminar members may be parallel to each other and located in spaced relation and separated by passageways.
  • the casing may have an inner surface with a spherical configuration
  • the socket body and the one or more thermally conductive parallel laminar members may have spherical outer surfaces with smaller radii than the radius of the casing inner surface to permit rotation of the socket mount within the casing about the hinge axis.
  • the thermally conductive parallel laminar members may extend radially of the hinge perpendicular to the hinge axis, each laminar member having a peripheral configuration with an outer radial dimension less than the radial dimension of the casing in the direction extending from the hinge axis. This configuration permits rotation of the socket mount body and heat sink so that the lamp may pivot out of the aperture without interruption of the light beam by the edge of the housing. This provides an efficient scoop light fitting.
  • the tilt actuator may comprise a motor, typically a stepper motor mounted on the casing.
  • the motor may be located adjacent the axis of the unit.
  • One or more laminar members may include an engagement to engage the tilt actuator to enable the socket mount and lamp to be pivoted from the retracted position to the deployed position.
  • the engagement of the one or more laminar members may be a toothed rack referred to in this specification as a tilt rack, arranged to engage a pinion of a tilt motor or other tilt actuator.
  • the tilt motor is a stepper motor mounted on the casing. The motor may be located adjacent the central axis of the unit. Actuation of the tilt motor causes the socket mount, lamp and heat sink to move between the retracted position and a deployed position.
  • a location of the tilt rack circumferential! y of the heat sink provides an efficient and convenient arrangement for adjustment of the orientation of the lamp unit. Precise and reproducible control of the tilt angle is facilitated.
  • the engagement or toothed rack is provided on a laminar member having a spherical outer surface with a maximum radius. This allows for a greater degree of angular movement when pivoting the socket mount from the retracted position to the deployed position, so that the lamp may extend by a greater distance from the ceiling aperture in use.
  • the laminar member may be fin-shaped.
  • the one or more laminar members may be perforated to reduce weight and increase ventilation.
  • the one or more laminar members extend outwardly from an opening defined by the socket body.
  • At least a portion of the outer surface of the socket body may have a radius which is the same as the radii of the outer surfaces of the one or more of the laminar members.
  • At least a portion of the outer surface of the socket body has a radius which is the same as the radius of the laminar member with a maximum radius.
  • the laminar members may have an outer radial dimension as disclosed above and an inner radial dimension configured to provide clearance from the housing, casing and rotational actuator as the socket mount moves from the retracted position to a deployed position.
  • the configuration may have the shape of a sharks fin.
  • the configuration may be selected so that each member has a maximum size to optimise the heat absorbing and radiating capacity.
  • the configuration may be selected so that one or more of the laminar members overhang the housing. This allows for longer angular movement when pivoting the socket mount from the retracted position to the deployed position.
  • the parallel laminar members have outer edges which form a part-spherical outer surface to the heat sink and the socket body has a spherical or part-spherical radially inwardly facing socket surface.
  • the radius of the socket surface may be greater than the radius of the outer edges of the heat sink so that the heat sink may rotate around both the hinge axis and also about a vertical axis, providing a universal mounting for the lamp unit.
  • one of the parallel laminar members acts as a driving laminar member, such as a fin-shaped driving laminar member.
  • the driving laminar member may extend in or adjacent a vertical plane passing through the centre of the part- spherical socket body so that the engagement or toothed rack is located at a maximum radius from the hinge axis.
  • the driving laminar member may have a circumferential toothed rack or friction drive surface. This allows the rack or surface to have a maximum length, optimising the responsiveness of the tilt actuator and permitting use of a lower power or less expensive drive motor. Furthermore the tilt actuator may be located at a maximum distance from the lamp, reducing heating of the motor by the lamp in use.
  • centrally extending driving laminar member may have a maximum length, to maximise the extent of the downward, scoop like movement of the lamp as it is deployed. Also location of this drive mechanism on the longest fin ensures that it receives maximum convection and conduction cooling. Equatorial location of the drive plate ensures that the forces applied to the drive mechanism have balanced reducing wear on prolonged use.
  • At least a portion of the heat sink is deployed at least partially through the aperture tilted relative to the housing when in a fully deployed position. This configuration allows improved ventilation using air within the room into which the deployed lamp is extended.
  • the housing comprises a collar.
