Abstract

A gas-discharge head lamp for a motor vehicle is disclosed. The head lamp includes a hermetic glass enclosure, a first discharge unit disposed in the glass enclosure to generate a high beam, a second discharge unit dispose in the glass enclosure to generate a low beam, an insulation tube connected connection lead wires extended from the first and second ground electrodes of the first and second discharge units and connected to an external ground power, and a base joined to the glass enclosure to allow the head lamp to be held in an opening of a reflector. Each arc-vessel of the first and second discharge units exhibits a single color or two different colors. Thus, a conversion of a light beam between a high beam and a low beam is achieved by selectively supplying current to the first or second discharge unit, without a conventional electrical or mechanical converting unit.

Description of the invention (2) The gas discharge headlamp includes the base 50 as described above. The base 50 may have various shapes, so that the gas discharge headlight can be fixedly connected to an opening of a reflection cover (not shown in the figure). The casing tube 10 is connected to the base 50, and an arc chamber J2 is provided in the center thereof. The arc chamber 12 includes a chamber 13 which can be filled with, for example, xenon and mercury vapor, or a metal halide mixture, if necessary. The discharge electrode groups 17 and 18 protrude into the chamber 13, and the arc chamber 12 is connected to the cylindrical extension seals 15 and 16. The cylindrical extension seal 15 embedded in the base 50 is provided with a lead wire 2 丨 for the lead wire of the discharge electrode 17, and the cylindrical extension seal 1 is arranged on the opposite side of the cylindrical extension seal 5 The other electrode 22 is connected to the discharge electrode 18.

To protect the arc chamber 12 and shield the ultraviolet discharge generated when the gas discharge headlamp is operating, the casing tube 10 may be made of glass. The above-mentioned conventional gas discharge headlamp emits light from a high-beam lamp and a low-beam lamp from a single discharge box. To convert a high-beam headlight into a low-beam head, or vice versa, traditional gas discharge headlamps often use magnetic reflection or motor-driven devices. Because this kind of conversion technology between high-beam and low-beam lamps may result in the loss of function due to the failure of the magnetic system or the failure of the electronic or motor mechanism ', the reliability of its products is quite low. In addition, 'because high-beam and low-beam lamps are operated with a single discharge box of the same color, it cannot meet consumers' needs for colored beams.
