1. A bearing structure configured to carry a high-low-voltage conversion circuit, and comprising:
an insulation carrier comprising a first surface and a second surface opposite to each other;
a first conductor layer and a second conductor layer coated on the first surface and the second surface, respectively, wherein a voltage difference is formed between the first conductor layer and the second conductor layer;
a first trench disposed on the first surface and surrounding an outer peripheral edge of the first conductor layer, wherein the first conductor layer is extended from the first surface into the first trench, and the outer peripheral edge of the first conductor layer is located at a bottom of the first trench; and
a first insulation material covering the outer peripheral edge of the first conductor layer and filled in the first trench.
