Abstract:
A load control device for an electrical load may operate in a normal mode and a burst mode to adjust the amount of power delivered to the electrical load. The load control device may comprise a control circuit that operates in the normal mode to regulate an average magnitude of a load current conducted through the load between a maximum rated current and a minimum rated current. During the normal mode, the control circuit may control the operating period of a load regulation circuit between a high-end operating period and a low-end operating period. The control circuit may operate in the burst mode to regulate the average magnitude of the load current below the minimum rated current. During the burst mode, the control circuit may adjust the low-end operating period to be less than or equal to a minimum on time of the load regulation circuit.

Claim (Index 15):
A method of controlling an intensity of a light-emitting diode (LED) light source, the method comprising:\n generating at least one drive signal for controlling an LED drive circuit to adjust a magnitude of a load current conducted through the LED light source and adjust the intensity of the LED light source, the at least one drive signal characterized by an operating period and a duty cycle; receiving a load current feedback signal that indicates the magnitude of the load current; operating the LED drive circuit in a first state and a second state on a periodic basis; controlling the LED drive circuit in the first state during a first time period in which an on time of the at least one drive signal is adjusted in response to the load current feedback signal to regulate a peak magnitude of the load current towards a target current; controlling the LED drive circuit in the second state during a second time period in which adjustment of the on time of the at least one drive signal in response to the load current feedback signal is ceased; adjusting an average magnitude of the load current by adjusting lengths of the first and second time periods; and adjusting the operating period of the at least one drive signal to a low-end operating period by adjusting the on time of the at least one drive signal to a value less than or equal to a minimum on time while holding the duty cycle of the at least one drive signal constant.
