Abstract
An electric light bulb type light source apparatus includes a base, an insulated power source circuit, a light source unit, a light source drive circuit, a speaker, a speaker drive circuit, a plurality of substrates, and a casing. The insulated power source circuit has a transformer that insulates a primary side circuit from a secondary side circuit, converts a voltage to a first DC power source voltage, and outputs the first DC power source voltage. The light source drive circuit drives the light source unit by using the first DC power source voltage output from the power source circuit. The speaker drive circuit drives the speaker by using the first DC power source voltage output from the power source circuit. On the plurality of substrates, the power source circuit, the light source drive circuit, and the speaker drive circuit are mounted. The casing contains the plurality of substrates.
