The present invention relates to a control module of or for a light system and related methods.
Lighting in art galleries typically comprises of a plurality of light fittings that each carry a replaceable lamp or lamps to illuminate artwork from above. The light fittings may include a base that can be used for connecting the light fitting to a mounting track.
A mounting track may be secured to a wall or ceiling of a building and may carry a plurality of light fittings spaced apart from each other along the track. The track is preferably of a constant cross section along most of its length and the base of a light fitting can be releasably engaged thereto to be positioned anywhere along the length of the mounting track. Galleries often need to change the lighting configuration of gallery rooms and so a quick release and install connection system is desirable. Light fittings can then be easily and quickly added or removed from a room and the base and track systems used, facilitate this.
Such systems may go by the general name of track lighting. US patent U.S. Pat. No. 7,507,005 shows an example. For each such systems, each light fitting may have a base that is of the same shape to be able to connect with tracks of a matching cross-sectional profile. The track itself may carry busbars along its length and with which terminals of the base of a light fitting can connect. This allows for power to be supplied to the light fitting to illuminate its lamp, without needing to additionally connect a separate power plug. Upon connecting the base to a track, the electrical power connection is hence automatically established.
Light fittings may include a tilt mechanism dependent from the base. This mechanism allows the angular position of a light bulb of the fitting to be adjusted.
Light fittings may from time to time need to be adjusted so that light is projected in a different direction. This requires a person to manually manipulate the light fitting such as by moving the tilt mechanism of a light fitting. This is easy to do where the light fitting is able to be reached from ground level. But when light fittings are located up high adjustment may require the use of a ladder. This can be time consuming and potentially also dangerous.
There is hence a need to improve the convenience and reduce the danger of adjusting light fittings.

In
In the example shown in
The control module A facilitates the creation of a connection between the light fitting B and the control module A and between the track C and the control module A.
The light fitting coupler 3B includes a light fitting plug 10 that is able to be releasably coupled to a second coupler 11. The second coupler 11 can receive the light fitting coupler 3B is a secure manner to hold the light fitting B to the control module A.
The coupling of the light fitting B to the module A and/or the track C and the coupling of the module A with the track C may be a quick release format so that light fittings can be quickly interchanged with the control module A and/or the track C.
The light fitting coupler 3B may be releasably attached to the body 7 of the light fitting or may be permanently engaged with the body 7. The light fitting coupler 3B may be releasably attached to the body 7 of the light fitting or may be permanently engaged with the body 7 to present the light fitting coupler 3B for connection with the second coupler 11 and preferably also with the track C.
The light fitting coupler 3B is preferably of a shape and configuration to also be able to connect to the track C at the track coupler 1. This allows for the light fitting B to also be directly engaged to the track C. The light fitting coupler 3B is preferably of a shape that allows for the light fitting to mechanically couple directly to the supporting power track coupler 12 of the supporting power track 1 and also to the second module coupler 11. The light fitting coupler 10 is preferably also able to directly and indirectly electrically connect to the supporting power track 1.
The control module A may have several functions including the function of transferring power from the track C to the light fitting B preferably via the track coupler 1, the first coupler 3A, the second coupler 11, and the light fitting coupler 3B, to power at least one lamp 14 of the light fitting B.
The supporting power track C may include electrical contacts or terminals or busbars (hereinafter ‘electrical terminals 13’) in a channel 12 of the track C that, when aligned with corresponding electrical terminals of the light fitting coupler 3B are able to make an electrical connection for the supply of electrical power to a lamp 14 of the light fitting 7.
The supporting power track C may include electrical contacts or terminals or busbars (hereinafter ‘electrical terminals’) that, when aligned with corresponding electrical terminals of the first coupler 3A are able to make an electrical connection for the supply of electrical power the control module.
The light fitting coupler 3B (whether provided removable or integrally formed with or permanently attached to the body 7) is able to also make an electrical and a mechanical and releasable connection with the control module B at the second coupler 11.
The control module B includes a second module coupler 11 which may for example comprise of a receptacle or socket in the body 2 of the module. The receptacle or socket can receive the light fitting coupler 3B into it as seen in
The second coupler 11, as well as providing releasable mechanical engagement with the light fitting coupler 3B, may also provide for an electrical connection between the control module A and the light fitting B. Electrical terminals may be provided within the receptacle or socket of the second coupler 11 with which electrical terminals of the light fitting coupler 3B can electrically connect and thereby allow for electrical power to be transferred to the light fitting B for the purposes of controlling and/or powering the lamp or lamps of the light fitting B.
The first coupler 3A is able to be utilised for connecting the control module A to the supporting electrical power track C. The format of connection of the first coupler 3A to the supporting electrical power track 1 is preferably the same as that of the light fitting coupler 3B to the second coupler 11. This allows for a releasable connection to be established to the supporting power track C for the control module A.
The first coupler 3A may be integrally formed or permanently connected to the main body 2 as part of the control module A or may be a separate component for releasable connection to the main body 2. Its form and function is preferably such as to be able to be received mechanically by the track coupler 2 in a releasable manner.
The first coupler 3A may also establish an electrical connection with the electrical terminals 13 of the track C. The first coupler 3A may include electrical contacts to establish an electrical connection with the electrical terminals 13 of the track C and allow for power to be transmitted between the control module A and the track C. The control module A may include electrical connections to transfer power from the supporting power track C via the control module 2 to the light fitting 7. Such power may also be drawn from for the purposes of control of the control module C.
The control module C may include electric and/or electronic components that may preform at least one function. The components are preferably contained in the main body 2 of the module C.
Control module A may function to cause a one axis rotation of the module relative the track C when connected to the track C. Such can allow the control and adjustment and readjustment of the orientation of the light fitting B relative to the track C. In the preferred form the control module A is configured to provide for a tilt axis TT to allow for the light fitting B to rotate about this axis TT. This allows for light from the light fitting to be projected in a new direction.
In a preferred form the control module A is also able to control and reposition the light fitting B by virtue of the control module establishing a controllable pan axis PP. The light fitting is able to be rotated about the axis PP. The control and repositioning is preferably provided by a position controllable gimbal 6 of the module A. The gimbal 6 may provide for the axis or axes of rotation, the rotation controlled for example by servo motors that are able to be controlled by remote control for rotation to adjust the pan and/or tilt axes positioning of the light fitting. The main body 2 may hence comprised of a gimbal 6 and a housing 5 able to couple to the body gimbal of the module A in a rotational manner so that the gimbal 6 and housing 5 are able to rotate relative to each other about the axis TT. The gimbal may also able to be rotationally coupled to the bearing 8 which is connected or connectable to the first connector 3A to allow for rotation about the axis PP. A servo motor or other types of position control motor can be used for each of the pan and/or tilt mechanisms and are preferably reliant on power provided via the track C. The control is preferably exercised by a controller such as a remote controller 16 that may rely on a wifi or RF or Bluetooth or other wireless transmitting protocol to communicate with a receiver R of the control module A. The receiver R of the module A is preferably coupled to an electronic controller of the control module A to control the servo motors and/or other control elements carried by the control module A for positional and/or other control of the light fitting. Alternatively or additionally, control may happen via the track C by way of electrical or electronic control signals transmitted to the module A. This may happen via the electrical connections are herein before described.
Control signal or signals, whether wirelessly or via the track, are able to be transferred by the control module A to the light fitting, should the light fitting be of a kind that has some functionality responsive to input control.
In an alternative form and as shown in
The alternative connector 19 may provide an electronical connection with the terminals 13 of the supporting power track C to transfer power via a cable 20 to the module A for transfer to the light fitting B. The alternative connection 19 need not be of a strong mechanical type to also support the weight of the light fitting and may merely be sufficiently strong for making an electrical connection. The first connector 3A, making a mechanical connection with the supporting power track, provides for mechanical connection of sufficient strength and support to hold the light fitting B.
The control module may, in addition or alternative to position control of the light fitting relative to the track, also control any one or more of the following degrees of freedom that may be provided for or be facilitated of supported by the light fitting:
Light spread control may be achieved by control over individual lamps of a light fitting. Likewise light intensity control may be so achieved or by way of adjusting voltage supply to a lamp of lamps of the light fitting.
