A control circuit and method for a bleeder, a chip, and a driver system. The bleeder control circuit is connected to a dimmer detector used for detecting the presence or absence of a dimmer and a type of the dimmer. The control circuit of the bleeder is used to receive a detection signal outputted by the dimmer detector, and generate a control signal for the bleeder according to the detection signal, the control signal is used to control an operating state of the bleeder. The application correspondingly generates a control signal for a bleeder according to a detection signal indicating the presence or absence of a dimmer and the type of the dimmer so as to control the bleeder to operate only at a given phase interval, and may thereby reduce the power consumption of the bleeder when ensuring the stable operation of a dimmer.

Photographic lighting devices, systems, and methods having a plurality of electrical energy storage/discharge (EESD) elements and/or one or more light sources in a single photographic lighting device to perform one or more photographic lighting effects. EESD elements and one or more light sources can be configured to have multiple separate light emissions occur in a single image acquisition window. The multiple light emissions are separated in an image acquisition window by a time period that is about shutter speed exposure time/(N1), where N is the number of light emissions. In one such example, two light emissions are separated by a time period that is about shutter speed exposure time/(N1).
