Abstract:
The invention provides a lighting unit, comprising a light source and a light sensor arrangement. An optical feedback path is provided from the light source (or another light source in the same overall system) to the light sensor arrangement. The light source is turned on in response to an external input and is maintained on as a result of the optical feedback path. This lighting unit can be turned on using an signal such as an optical signal which is received from an external source, and then maintained on using optical feedback from the light source itself. This makes it possible to control a lighting unit area such as a wall using an external device such as a torch or laser pointer, without the need for complex electronic protocols.

Claim (Index 15):
A method as claimed in  claim 13 , comprising:\n turning off the light source in response to: a second external light input different to the first external light input; or a switched interruption of power to the lighting unit; or a non-light external input.
