Abstract
PURPOSE:To obtain uniformly distributed light over the whole area of lamp and facilitate manufacture by heating a straight glass bulb in circular form, pressing to the above and down, deforming the section into eliptic form, pressing the center of the bulb, putting the upper and lower inner surfaces in close contact, and thereby forming a revolving air-tight space. CONSTITUTION:The whole straight glass bulb 21 with circular section having transparency is heated to around the softening point, and the glass bulb 21 is pressed in the vertical direction to deform it into approx. eliptical section. Then the center is pressed locally while both ends of bulb 21' in the longitudinal direction are left unprocessed, and the upper and lower central inner surfaces of the bulb 21' are put in close contact except the two ends in the longitudinal direction, to form a revolving airtight space 23. Then certain amounts of mercury and rare gas are encapsulated in the airtight space 23 as discharging gas.
