An active cooling device in the form of a torsional, oscillating synthetic jet is provided. Fins are oscillated in a manner that creates a flow of air that can be used to cool an electronic device such as a lamp. Embodiments of the active cooling device can be compact and readily incorporated within heat sinks of different sizes and configurations. The flow of air can be provided as jets of air distributed over multiple directions as may be desirable with certain electronics such as an omnidirectional lamp.
