Abstract

PURPOSE: To provide a method of manufacturing a reflection type electric bulb, according to which sighting projections having such a height as to tilt the sighting plane of a front lens within an angle of 0.5° - 1.5° to the optical axis are formed on the outer surface of the lens, and then the lens formed with projections is coupled with a reflecting mirror, so that requirement for adjustment of the height of said projections can be made unnecessary, that is required otherwise after completion of the lamp, thus preventing that dimmed light be diffused upward.
