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 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;
wherein 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; and
if the TRIAC dimmer is determined to be in the second condition, generate the second signal to cause the switch to remain closed for a first period of time until at least the TRIAC dimmer changes from the second condition to the first condition.

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.

18. 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 information associated with the first signal; determining whether the TRIAC dimmer is in a first condition or a second condition based on at least information associated with the first signal; generating a second signal based on at least information associated with the first signal; and outputting the second signal to a switch; wherein the process for generating a second signal based on at least information associated with the first signal includes; if the TRIAC dimmer is determined to be in the first condition, generating the second signal to cause the switch to be opened and closed corresponding to a modulation frequency; and if the TRIAC dimmer is determined to be in the second condition, generating the second signal to cause the switch to remain closed for a first period of time until at least the TRIAC dimmer changes from the second condition to the first condition. - View Dependent Claims (19, 20, 21, 22, 23, 24, 25, 26)
