ELECTRODELESS BULB FOR ELECTRODELESS LAMP, INCLUDING DISCHARGE ELECTRODE ARRANGED IN ELECTRODELESS BULB

摘要

PURPOSE: An electrodeless bulb is provided to shorten the initial lighting time and re-lighting time of the electrodeless bulb, and achieve improved efficiency of light conversion. CONSTITUTION: An electrodeless bulb(160) comprises a bulb(162) having a space(161) filled with a light emitting material for emitting light by a microwave; and a discharge electrode(164) mounted in the bulb such that the discharge electrode generates an instantaneous arc during lighting of a lamp so as to facilitate a lamp lighting operation.
