Lighting module as a tool for connecting/disconnecting another lighting module
A lighting module ( 1 ) having a connection end ( 2 ) for connection to a lamp holder ( 3 ), and a light output end ( 4 ) for outputting light, wherein the lighting module ( 1 ), at the light output end ( 4 ), is provided with a mechanical interface comprising first ( 6 ) and second ( 7 ) protrusions extending in a direction parallel with a longitudinal axis ( 13 ) of the lighting module and being configured to interact with corresponding protrusions ( 6′,7′ ) on an identical mechanical interface to transfer at least one of a rotational force and a pulling force to the lighting module ( 1 ), so that a device ( 1 ′) provided with such an identical mechanical interface can be used as a tool for connecting/disconnecting the lighting module ( 1 ). An advantage is that it is possible to utilize one lighting module as a tool to connect/disconnect another lighting module from a lamp holder.
1. A lighting module comprising:
a connection end for connection to a lamp holder, and
a light output end for outputting light,
wherein said light output end comprises a mechanical interface comprising first and second protrusions extending in a direction parallel with a longitudinal axis of the lighting module,
wherein said first and second protrusions are configured to engage with corresponding protrusions on a mechanical interface of another identical lighting module and configured to transfer at least one of a rotational and a pulling force to said lighting module, such that said another identical lighting module is operable to connect and/or disconnect said lighting module.
2. The lighting module according to claim 1 , wherein said first and second protrusions are configured to be engaged with the corresponding protrusions on the identical mechanical interface after a relative rotation between said mechanical interfaces about the longitudinal axis of the lighting module.
3. The lighting module according to claim 1 , wherein said first and second protrusions are configured such that relative movement between the mechanical interfaces in a direction parallel with the longitudinal axis of the lighting module is prevented when said first and second protrusions are engaged with the corresponding protrusions on the identical mechanical interface.
4. The lighting module according to claim 1 , wherein said first and second protrusions are tapered in such a way that an intermediate recess formed between said first and second protrusions has a neck that prevents relative movement between the mechanical interfaces in a direction parallel with the longitudinal axis of the lighting module when said first and second protrusions are engaged with the corresponding protrusions on the identical mechanical interface.
5. The lighting module according to claim 4 , wherein the necks of the intermediate recesses are sufficiently wide to allow corresponding protrusions on the identical mechanical interface to pass through the necks in a direction parallel with the longitudinal axis of the lighting module.
6. The lighting module according to claim 1 , wherein said protrusions are arranged along a periphery of said lighting module.
7. The lighting module according to claim 1 , wherein said lighting module is cylindrical, and said protrusions are an extension of a wall of said cylindrical lighting module.
8. The lighting module according to claim 7 , wherein said lighting module is circular cylindrical.
9. A set of lighting modules comprising a plurality of lighting modules according to claim 1 , wherein a first lighting module in said set of lighting modules can be used as a tool for connecting/disconnecting a second lighting module in said set of lighting modules.
10. A luminaire comprising:
a lighting module according to claim 1 ; and
a lamp holder for receiving said lighting module.
