摘要： A ballast controller integrated circuit which executes a specific set of instructions via an integrated state diagram architecture to control a fluorescent lamp or high intensity discharge lamp and protect the ballast. The state diagram architecture controls powering up and down of the IC and the half-bridge circuit driven by the IC, preheating and striking of the lamp, running of the lamp, sensing for numerous possible fault conditions, and recovering from these fault conditions based on the normal maintenance of a lamp, while requiring fewer internal and external components than previous electronic ballasts.

摘要： A high pressure discharge lamp is provided with an arc tube and a starter. The starter includes a ferroelectric ceramic capacitor element with non-linear characteristics and a semiconductor switching element, connected in parallel to the arc tube. A pulse stopping thermally-actuated switch is connected in series to the ferroelectric ceramic capacitor element and is operated to OFF by heating of a heating resistor in a non-lighted state of the lamp. Without accompanying reduction of a starting function due to a temperature rise of the ferroelectric ceramic capacitor element, a safety function against a non-lighted state of the lamp is provided.

摘要： The multiple output power adapter includes an AC input receptacle which plugs into an AC power socket. The AC input receptacle is connected to an input of a single output power converter which converts the input AC voltage into an output DC voltage of a specified level. Connected to the output terminal of the single output power converter is a DC-DC module converter which converts the output DC voltage into multiple output DC voltages. Additionally, the multiple output power adapter includes an output wire connected to the output terminal of the single output power adapter in parallel with the DC-DC module converter. The output wire and the output terminal of the DC-DC module converter are both then connected to an electrical component connector. With this structure, DC power can be supplied to an electronic device at a voltage level output by the single output power converter and/or at multiple voltage levels output by the DC-DC module converter.
