Module for mounting to a luminaire
A module ( 10 ) adapted for fitting to a luminaire ( 100 ), comprising: a main module housing ( 50 ); a rotate plate ( 60 ) coupled to the main module housing, and rotatable relative to the main module housing; a connection interface ( 70 ) for connecting the module to a corresponding connection interface of the luminaire, wherein the connection interface ( 70 ) is connected to the rotate plate; and a rotatable electrical connection ( 80 ) between the rotate plate and the main module housing, wherein the rotate plate ( 60 ) comprises a locking feature ( 62 ) which engages with a retaining feature ( 52 ) of the main module housing to lock the rotate plate with a selected relative rotational position between the rotate plate and the main module housing, wherein the locking feature ( 62 ) is provided on an elastically deformable region ( 64 ) of the rotate plate such that the locking feature can be brought out of engagement from the retaining feature by manual deformation of the deformable region ( 64 ) thereby to enable selection of the relative rotational position.
1. A module adapted for fitting to a luminaire, comprising:
a main module housing;
a rotate plate coupled to the main module housing, and rotatable relative to the main module housing;
a connection interface for connecting the module to a corresponding connection interface of the luminaire, wherein the connection interface is connected to the rotate plate; and
a rotatable electrical connection between the rotate plate and the main module housing,
wherein the rotate plate comprises a locking feature which engages with a retaining feature of the main module housing to lock the rotate plate with a selected relative rotational position between the rotate plate and the main module housing, wherein the locking feature is provided on an elastically deformable region of the rotate plate such that the locking feature can be brought out of engagement from the retaining feature by manual deformation of the deformable region thereby to enable selection of the relative rotational position.
2. The module of claim 1 , wherein the rotate plate comprises a disc having an arc slot and the main module housing comprises a marker pin which projects into the arc slot to indicate the selected relative rotational position.
3. The module of claim 2 , wherein the engagement between the arc slot and the marker pin defines the limits of the relative rotational position.
4. The module of claim 2 , wherein the deformable region is a region of the rotate plate which is located radially outside the arc slot.
5. The module of claim 4 , wherein the region of the rotate plate comprises a set of openings along a circumferential direction, each opening representing a particular relative rotational position.
6. The module of claim 2 , wherein the locking feature is located at a position of the deformable region corresponding to a middle of the arc slot along a circumferential direction.
7. The module of claim 1 , wherein the rotate plate comprises a finger tab at the location of the locking feature.
8. The module of claim 1 , wherein the locking feature comprises a projection extending from the rotate plate and the retaining feature comprises a plurality of receiving elements, wherein the projection can be received in a selected one of the receiving elements to lock the rotate plate to the main module housing.
9. The module of claim 1 , wherein the main module housing comprises a base plate and a cover, wherein a seal is provided between the base plate and the rotate plate.
10. The module of claim 1 , wherein the rotatable electrical connection comprises a conductor track plate rotationally fixed to one of the rotate plate and the main module housing, and a spring contact plate rotationally fixed to the other of the rotate plate and the main module housing.
11. The module of claim 10 , wherein the conductor track plate comprises a set of arcuate conductor tracks and the spring contact plate comprises a corresponding set of spring contacts each for contacting a respective one of the arcuate conductor tracks.
12. The module of claim 1 , comprising a wireless communications module in the main module housing.
13. The module of claim 1 , comprising a presence sensor in the main module housing.
14. A luminaire comprising:
a luminaire housing, comprising a connection interface for connection to a module; and
the module of claim 1 connected to the connection interface of the luminaire housing.
15. The luminaire of claim 14 , comprising a street light luminaire.
