Systems and methods for dimming control using triac dimmers
First Claim
1. A system for dimming control of one or more light emitting diodes, the system comprising:
- one or more signal generators configured to receive a first signal associated with a TRIAC dimmer, process the first signal, determine whether the TRIAC dimmer is in a first condition or a second condition, generate a second signal based at least in part on the first signal, and send the second signal to a switch;
wherein the one or more signal generators are further configured to;
determine whether the TRIAC dimmer is in a third condition; and
in response to the TRIAC dimmer being determined to be in the third condition, generate the second signal to cause the switch to remain open for a period of time.

Abstract
System and method for dimming control of one or more light emitting diodes. An example system includes one or more signal processing components configured to receive a first signal associated with a TRIAC dimmer, process information associated with the first signal, determine whether the TRIAC dimmer is in a first condition or a second condition, generate a second signal based on at least information associated with the first signal, and send the second signal to a switch. The one or more signal processing components are further configured to, if the TRIAC dimmer is determined to be in the first condition, generate the second signal to cause the switch to be opened and closed corresponding to a modulation frequency.

15. A method for dimming control of one or more light emitting diodes, the method comprising:
-
receiving a first signal associated with a TRIAC dimmer; processing the first signal; determining whether the TRIAC dimmer is in a first condition or a second condition based at least in part on the first signal; generating a second signal based at least in part on the first signal; outputting the second signal to a switch; and determining whether the TRIAC dimmer is in a third condition; wherein the generating a second signal based at least in part on the first signal further includes, in response to the TRIAC dimmer being determined to be in the third condition, generating the second signal to cause the switch to remain open for a period of time. - View Dependent Claims (16, 17, 18, 19, 20)
