An insulation reinforcing light bulb includes a light penetrable shell, a power receiving base, a heat sink and an assembling holder located between the light penetrable shell and the power receiving base, at least one light source baseboard located in the light penetrable shell and a power conversion board electrically connected to the light source baseboard and the power receiving base. The heat sink has a housing chamber to hold the power conversion board. The light bulb further includes an isolation element held in the housing chamber. The isolation element has an isolation wall interposed between the power conversion board and the heat sink to form a circuit housing compartment to hold the power conversion board, and a wiring outlet formed on the isolation wall to allow wires to be led from the power conversion board to connect to the light source baseboard. |
