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 1):
A lighting unit, comprising:\n a light source; a light sensor arrangement; and an optical feedback path from the light source to the light sensor arrangement, wherein the lighting unit is adapted to receive a first external input from a source external to the lighting unit for turning on the light source; wherein the light sensor arrangement is adapted to maintain the light source switched on in response to light output from the light source sensed by the light sensor arrangement through the optical feedback path, wherein an output from the light sensor arrangement directly connects to an input of the light source, so as to directly controlling an on state of the light source without the use of an intermediate processing device.
