Abstract
A strobe device that operates in multiple modes is disclosed. The strobe device may include an LED-based strobe element and a controller. In response to receiving a command to generate an output, the controller determines in which of at least a first mode and second mode to operate, and sends one or more signals to the LED-based strobe element based on the determination. The first mode and the second mode may differ from one another in at least one aspect, such as duration, luminosity, current supplied to LED, or wavelength range. The controller may select both of the first mode and the second mode (such as alternating between the first mode and the second mode). Or, the controller may select one of the first mode and the second mode. For example, depending on the ambient light at or near the strobe device, the controller may select either the first mode or the second mode.
