METHOD FOR MANUFACTURING ELECTRODELESS BULB OF ELECTRODELESS LAMP THROUGH SIMPLIFIED WORK PROCEDURES

摘要

PURPOSE: A method for manufacturing an electrodeless bulb is provided to prevent a dispersion of light and simplify work procedures by improving processes for manufacturing an electrodeless bulb. CONSTITUTION: A method comprises a first step of producing a bulb(105a) having a spherical shape of an electrodeless bulb of an electrodeless lamp; a second step of forming an injection port by mounting a tube having a predetermined length to the bulb; a third step of injecting a light emitting material and evacuating air through the injection port; and a fourth step of sealing the connecting portion between the bulb and the tube such that the bulb is sealed after injection of light emitting material and evacuation of air.
