ELECTRODELESS BULB, AND ELECTRODELESS LIGHTING SYSTEM HAVING THE SAME

摘要

Disclosed are an electrodeless bulb, and an electrodeless lighting system having the same. The electrodeless bulb includes: a light emitting unit having an airtight inside space; a main discharge material filled in the inside space of the light emitting unit and discharged by microwave, for emitting light; a discharge assistant material filled in the light emitting unit, for forming plasma in the inside space before the main discharge material generates plasma; and a discharge catalyst material filled in the light emitting unit, for inducing initial discharge of the main discharge material and the discharge assistant material. The lighting system improves lighting efficiency of the main discharge material filled in the light emitting unit, and has an eco-friendly characteristic by excluding an environmental contaminant such as mercury.
