摘要： The invention provides an arc tube with improved chromaticity and start-up characteristics that does not contain mercury, and provides a vehicle headlamp equipped with a metal halide lamp that contains no mercury in the arc tube. Among other improvements, the evaporation of low melting point metal halides is promoted and the start-up characteristics of the arc tube are improved.

摘要： In a method for manufacturing small tubular lamps, a moving amount of a tube stock is adjusted according to a wall thickness thereof to make the stock-guide amount uniform, and the internal pressure during the stock-guide step is also adjusted so as to produce a suitable dimension of the outside diameter thereof, whereby the working amount in the succeeding step is reduced to decrease errors in dimensional tolerances, particularly in wall thickness and internal volume.
