LIGHTING CONTROLLER
First Claim
Patent Images
1. A lighting controller suitable for replacing a conventional wall-mounted light switch, the controller comprising:
- a dimmer arranged to vary the electrical power of at least one electrical output of the controller;
a light sensor responsive to the intensity of visible light incident on the light sensor;
at least one manually-operable control; and
an occupancy sensor,wherein the dimmer is arranged to vary the electrical power of the output in response to operation of the manually-operable control and in response to signals generated by the occupancy sensor and the dimmer is further arranged to vary the electrical power of the output by reference to signals generated by the light sensor.

5. A lighting controller suitable for replacing a conventional wall-mounted light switch, the controller comprising:
-
a dimmer arranged to vary the electrical power of at least one electrical output of the controller; at least one manually-operable control; and a light sensor responsive to the intensity of visible light incident on the light sensor, wherein the dimmer is arranged to vary the electrical power of the output in response to operation of the manually-operable control; and wherein the dimmer is configured to vary the electrical power of the output in accordance with at least two operating regimes, one of the operating regimes being for the supply of power to incandescent lamps and another of the operating regimes being for the supply of power to non-incandescent lamps, and wherein the controller is configured to select an operating regime by reference to the response of the light sensor when the dimmer varies the electrical power of the output.
