Radio frequency (RF) controlled lamp with dimmer compatibility
First Claim
1. A radio frequency (RF) controlled lighting unit suitable for connection to at least one of a dimmer configured to adjust a phase cut angle of an input mains voltage from mains in accordance with an adjustable dimming level or an electronic switch configured to provide selection between an on-state and an off-state, the RF lighting unit comprising:
- a solid state light source;
a radio circuit configured to receive a wireless control signal, enabling control of the RF lighting unit;
a rectifier circuit configured to rectify the input mains voltage received from the dimmer or the electronic switch;
a first power converter configured to drive the solid state light source in response to the rectified input mains voltage and to deliver power to the radio circuit; and
a second power converter configured to deliver power to the radio circuit when the rectified input mains voltage becomes inadequate for the first power converter due to the phase-cut angle of the rectified input mains voltage or the off-state of the electronic switch.

Abstract
An RF controlled lighting unit is provided, suitable for connection to at least one of a dimmer for adjusting a phase cut angle of input mains voltage in accordance with an adjustable dimming level or an electronic switch for selecting between on-and off-states. The lighting unit includes a solid state light source; a radio circuit for receiving a wireless control signal; a rectifier circuit for rectifying the input mains voltage received from the electronic switch or the dimmer; a first power converter for driving the solid state light source in response to the rectified input mains voltage and delivering power to the radio circuit; and a second power convertor for delivering power to the radio circuit when the rectified input mains voltage becomes inadequate for the first power converter due to the phase-cut angle of the rectified input mains voltage or the off-state of the electronic switch.
