Abstract

A light dimmer circuit for use with light emitting diodes. Light emitting diodes (LEDs) are connected in parallel with capacitors, which are connected in parallel with LED drivers. The light dimmer circuit is capable of achieving a wide range of power levels to the LEDs.

Claims

1. An apparatus comprising:

a dimmer connected to a line voltage;

a transformer connected to an output of the dimmer;

a first LED driver connected to the transformer, the first LED driver having a first pair of driver terminals;

a first capacitor connected in parallel to the first pair of driver terminals;

a second LED driver connected to the transformer, the second LED driver having a second pair of driver terminals;

a second capacitor connected in parallel to the second pair of driver terminals;

a first string of LEDs connected in parallel to the first capacitor; and

a second string of LEDs connected in parallel to the second capacitor.

2. The apparatus as recited in claim 1, wherein the dimmer is a triac dimmer.

3. An apparatus comprising:

a dimmer connected to a line voltage;

a transformer connected to an output of the dimmer;

an LED driver connected to the transformer, the first LED driver having a pair of driver terminals;

a capacitor connected in parallel to the pair of driver terminals;

a connector connecting connected in parallel to the capacitor; and

a string of LEDs connected to the connector.

4. The apparatus as recited in claim 3, wherein the dimmer is a triac dimmer.
