A solid-state light bulb using an ion wind fan and a heat sink for thermal management can electrically isolate the heat sink to make it touch-safe. In one embodiment, the present invention includes a bulb housing, at least a portion of which is made of a dielectric material and a lens made of a dielectric material, wherein the lens and the bulb together define the inside and outside of the bulb. A heat sink and an ion wind fan providing forced convection for the heat sink thermally manage the solid-state light devices in the bulb. In one embodiment, the outside of the bulb is electrically isolated from the heat sink located inside of the bulb by at least the portion of the bulb housing that is made of the dielectric material.
