User control of an LED luminaire for a phase cut dimmer
First Claim
1. A phase cut angle converter with range detection for a phase cut dimmer comprising:
- a phase cut angle detector arranged to detect the phase cut angle presented by the phase cut dimmer blocking a portion of an alternating current mains power sine wave and output a phase cut level signal whose value is responsive to the detected phase cut angle;
a storage functionality comprising a memory, said storage functionality in communication with said phase cut angle detector and arranged to detect each of a minimum value and a maximum value for the phase cut level signal and store said minimum value and said maximum value on said memory; and
a signal adjustment functionality arranged to convert the phase cut level signal to a dimming signal responsive to said stored minimum value and said maximum value for the detected phase cut angle.

Abstract
A phase cut angle converter with range detection for a phase cut dimmer constituted of: a phase cut angle detector arranged to detect the phase cut angle presented by the phase cut dimmer blocking a portion of an alternating current mains power sine wave from reaching a power converter, and output a signal whose value is responsive to the detected phase cut angle; a storage functionality constituted of a memory in communication with the phase cut angle detector, the storage functionality arranged to detect each of a minimum value and a maximum value for the detected phase cut angle of the phase cut angle detector and store the minimum value and the maximum value on the memory; and a signal adjustment functionality arranged to convert the detected phase cut angle to a dimming signal responsive to the stored minimum value and the maximum value for the detected phase cut angle.

10. A method of converting a phase cut angle to a dimming signal, the method comprising:
-
receiving an alternating current power signal; detecting the phase cut angle presented by a phase cut dimmer blocking a portion of the received alternating current power signal; storing each of a minimum value and a maximum value for the detected phase cut angle of said phase cut angle detector; and converting the detected phase cut angle to a dimming signal responsive to the stored minimum value and the maximum value for the detected phase cut angle. - View Dependent Claims (11, 12, 13, 14)
