Title:
誘導給電式ガス放電ランプ
Document Type and Number:
Japanese Patent JP5400380
Kind Code:
B2
Abstract:
An inductively powered gas discharge lamp including both a power coil and a heating coils associated with each filament. The heating coils enable the filaments to be preheated before the starting voltage is applied through the power coils. The inductive power coils and the inductive heater coils are contained within the lamp envelope, allowing the lamp to be entirely sealed. A method of dimming the lamp also is disclosed. The lamp is dimmed by both decreasing the power applied to the power coils and increasing the power applied to the heating coils so as to prevent the arc from extinguishing under lower voltage conditions.
