Device for improving compatibility of solid state light sources with phase-cut dimmers

An extender device for suppressing flicker in a lighting unit including at least one light emitting diode (LED);

• the device comprising:
• an extender base configured to be inserted into a lamp socket connected to a dimmer, the lamp socket being configured to receive an incandescent lighting unit;
• an extender socket configured to receive the lighting unit including the at least one LED;
• and
• an adapter circuit located between the extender base and the extender socket, and configured to be electrically connected in parallel with the at least one LED when the lighting unit is inserted in the extender socket, wherein the adapter circuit suppresses flicker of the at least one LED caused by the dimmer.

A retrofit solid state light source device, comprising:

• a driver configured to receive a dimmed mains voltage from a dimmer and to output a drive current based on a dimming level of the dimmed mains voltage;
• a solid state lighting module comprising at least one solid state light source, the solid state lighting module being configured to receive the drive current from the driver;
• an adapter circuit connected in parallel with the solid state lighting module for suppressing flicker of the at least one solid state light source and/or improving compatibility of the at least one solid state light source with dimmers or other controllers;
• and
• a connector configured to connect the solid state light source device with a socket configured to receive an incandescent lighting unit.
