Flash-LED driver discharge control
First Claim
1. A discharge control assembly comprising:
- a discharge circuit selectively connectable to a driver circuit, the discharge circuit configured to provide a dominant discharge path for the driver circuit when the driver circuit is effectively decoupled from a first load in order to decay an electrical condition of the driver circuit produced prior to the driver circuit being effectively decoupled from the first load; and
a controller configured to selectively connect the driver circuit to a combination of the discharge circuit and the first load, and in at least one combination the discharge circuit is effectively coupled to the driver circuit when the first load is effectively decoupled from the driver circuit, the controller further configured to effectively decouple the driver circuit from the discharge circuit after the driver circuit has been decoupled from the first load.

Abstract
Various implementations include circuits, devices and/or methods that enable the repeated generation of controlled surges with lower risk of component failure. Some implementations include a discharge control assembly including a discharge circuit and a controller. In some implementations, the discharge circuit is selectively connectable to a driver circuit, and the discharge circuit is configured to provide a dominant discharge path for the driver circuit when the driver circuit is effectively decoupled from a first load in order to decay an electrical condition of the driver circuit produced prior to the driver circuit being effectively decoupled from the first load. In some implementations, the controller is configured to selectively connect the driver circuit to a combination of the discharge circuit and the first load, and in at least one combination the discharge circuit is effectively coupled to the driver circuit when the first load is effectively decoupled from the driver circuit.
