Conventionally, this type of headlight device uses two lights: a low beam lamp and a running beam lamp.
Both lamps were switched on and off. Moreover, these two lamps were generally incandescent bulbs or halogen bulbs. However, in recent years, from the perspective of energy conservation, research has been conducted into using discharge lamps with high light conversion efficiency in this headlamp device. In this case, two discharge lamps are considered for two types of illumination: a running beam and a passing beam. However, when a discharge lamp is used in a headlight device, unlike conventional light bulbs, the lighting device including the discharge lamp and the circuit for lighting the discharge lamp is bulky and heavy, and it is not economical. It was hot.

ル量を可変制御する制御手段を構成している。 As shown in FIG. 1, a DC lighting device 2 is connected to a DC power supply 1, and a high pressure discharge lamp 3 such as a metal halide lamp is connected to the output end of the DC lighting device 2. On the side of the high-pressure discharge lamp 3, a magnetic field applying means is provided in which a coil 5 is wound around an E-shaped core 4. The coil 5 has one end connected to a first contact 61 of the first changeover switch 6 and a second contact 72 of a second changeover switch 7 linked to the first changeover switch 6, and the other end connected to the It is connected to the second contact 62 of the first changeover switch 6 and the first contact 71 of the second changeover switch 7, respectively. A common terminal 6c of the first changeover switch 6 is connected to the positive terminal of the DC power supply 1, and a common terminal 7c of the second changeover switch 7 is connected to the negative terminal of the DC power supply 1. In both the changeover switches 6 and 7, the first contacts 61 and 71 are turned on and off at the same time, and the second contacts 62 and 72 are turned on and off at the same time. The high pressure discharge lamp 3 has an inner tube 3c with electrodes 3a and 3b arranged opposite each other as shown in FIG.
is further surrounded by an outer tube 3d. As shown in FIGS. 3 and 4, the high-pressure discharge lamp 3 is held substantially horizontally within a reflecting mirror case 8 having a substantially hemispherical shape. The front opening of the reflective mirror case 8 is closed with a specially processed front glass 9.
The magnetic field applying means is arranged so as to apply a magnetic field substantially perpendicularly to the arc of the high pressure discharge lamp 3 in a horizontal direction by energizing the coil 5. The first and second changeover switches 6 and 7 constitute a control means for variably controlling the vector amount of the magnetic field.
次にこのように構成された本発明実施例装置の
動作について述べる。 Next, the operation of the apparatus according to the embodiment of the present invention constructed as described above will be described.

ビームとなる。 Now, when the first contacts 61 and 71 of the first and second changeover switches 6 and 7 are turned on and the second contacts 62 and 72 are turned off, the high-pressure discharge lamp 3 is turned on as shown by the solid arrow "I" in FIG. arc current flows in the direction and
A magnetic field is generated in the direction indicated by the solid arrow "H" in the figure. According to the left-hand rule of framing, a force is generated in the direction shown by the solid arrow "F" in FIG. Can be bent. In this way, the beam emitted through the front glass 9 becomes a beam directed downward compared to the beam emitted when the arc indicated by the dotted line in the figure is horizontal, and becomes a so-called passing beam.

ームとなる、いわゆる走行ビームとなる。 In addition, the first and second changeover switches 6 and 7 are switched to turn off the first contacts 61 and 71, and the second contacts 62 and 7 are turned off.
2, the direction of the current flowing through the coil 5 is reversed, thereby reversing the vector of the magnetic field. That is, as shown by the dotted arrow "H" in FIG. 2, a magnetic field is applied in the opposite direction.
As a result, a force is generated in the high pressure discharge lamp 3 in the direction indicated by the dotted arrow "F" in FIG.
The arc between both electrodes 3a and 3b is bent downward as shown in FIG. In this way, the beam emitted through the front glass 9 becomes a so-called traveling beam, which is an upward beam compared to the beam emitted when the arc indicated by the dotted line in the figure is horizontal.

性の向上を図かることができる。 In this way, the arc of the high-pressure discharge lamp 3 is bent upward and downward by changing the direction of the magnetic field applied to the arc, thereby switching between the passing beam and the traveling beam. With just one, it is possible to reduce the size and weight of the device and improve economic efficiency.

よい。 In addition, in the above embodiment, the direction of the magnetic field applied to the arc is reversed and the arc is bent upward and downward to switch between the passing beam and the traveling beam, but the invention is not limited to this. The arc may be bent only upwards or downwards by applying no magnetic field or not at all, and the arc may be switched between a passing beam and a traveling beam when no magnetic field is applied.Also, the strength of the magnetic field applied to the arc may be changed by changing the current. The bending condition of the arc may be varied by control to switch between the passing beam and the running beam, and if necessary, the switching between the passing beam and the running beam may be performed by changing the vector amount of the magnetic field applied to the arc. It is fine as long as it is something.
