A non-isolating circuit assembly includes a heat sink, a circular supporting member, a thermal insulation pad, and a light emitter. The heat sink has an inwardly-shrank platform. The circular supporting member is disposed around the outer edge of the inwardly-shrank platform. The thermal insulation pad is disposed on the inwardly-shrank platform and the circular supporting member. The area of the thermal insulation pad is larger than that of the inwardly-shrank platform, and the circular supporting member supports the outer edge of the thermal insulation pad. The light emitter is disposed on the thermal insulation pad.
