Abstract

PURPOSE:To improve the fixing property between a lens and a reflecting mirror without expansion of a gas in the reflecting mirror by successively executing three steps of installation of a tubular bulb into the reflecting mirror, installation of a cover, and adjustment of atmospheric pressure in the reflecting mirror to a required pressure. CONSTITUTION:A tubular bulb 2 is installed to a reflecting mirror 1, a lens for forming a cover A through a synthetic resin adhesive B is installed to the reflecting mirror. When the bulb 1 is heated to a determined temperature higher than the temperature at the time of lighting, the adhesive B is laid into fused state. Thereafter, the adhesive B is hardened by cooling, and the atmospheric pressure in the reflecting mirror is automatically adjusted to a pressure lower than outside pressure, so that the fixing property between the lens and the reflecting mirror is increased without expansion of the gas in the reflecting mirror.
