Problems solved by technology

[0011] However, in the headlights of two-wheeled motor vehicles and four-wheeled motor vehicles where there is less space for installing such mechanisms, the installation space for the solenoid 28 cannot be ensured, so the above-mentioned structure cannot be adopted.

Embodiment 1

[0029] Figure 1 ~ Figure 3 is a diagram showing the first embodiment.

[0030] The discharge bulb 1 is inserted into the lamp cap 3 to be fixed. Protrusions to the left and right are arranged on the lamp cap 3 . In addition, the base 3 is inserted into a cylindrical socket 4 . The lamp holder 4 is fixed in the lamp basket, and the lamp holder 4 is provided with holes to be fitted with the protrusions 5 of the lamp base 3 on the left and right. Therefore, the protrusions 5 of the base 3 fit into the left and right holes provided in the socket 4 , and the base 3 can rotate slightly in the Y direction in the socket 4 with the protrusions 5 as axes.

[0031] The inner surface of the socket 4 is cut away near the end of the socket 4 so that the base 3 can be rotated, and the wall of the socket 4 is gradually thinned.

[0032] In addition, a member forming a lever, for example, a lever-shaped member, is provided on the lamp cap. In the case of this embodiment, a rod-shaped lev...

Embodiment 2

[0041] Figure 4 It is another embodiment of the present invention.

[0042] It is an example where the electromagnet A7 is replaced with a helical coil. When the current does not flow through the electromagnet B8 , the lever 6 is pulled by the helical coil 10 , and the light emitting part 2 is located on the center line CL of the lamp socket 4 . This position is the position of the high beam as described in the first embodiment above.

[0043] When current flows through the electromagnet B8, the lever 6 is attracted to the magnetic pole of the electromagnet B8 against the tension of the helical coil 10, and the light emitting part 2 moves to a position higher than the centerline CL of the lamp holder 4. This position is the low beam position as described in the first embodiment above.

[0044] Of course, in Figure 4 Among them, the helical coil 10 and the electromagnet 8 can also be installed in reverse, and the low beam is formed under the state that the electromagnet B...

Abstract

The object of the present invention is to provide a headlight device for a vehicle, which allows a two-wheeled vehicle that is equipped with only one discharge lamp to obtain light distribution of high beam and low beam. The solution of the present invention is a headlight device for vehicle comprising a lever-like member 6 provided at a rear-face part 3a of a socket 3 in which a discharge lamp 1 has not been fitted, and at least one electromagnet 7 (8) arranged in the vicinity of the lever-like member 6 whereby by attracting the lever-like member 6 with the electromagnet 7 (8), the socket 3 with the discharge lamp 1 fitted therein is structured to be rotated by a given angle.

Description

technical field [0001] The present invention relates to a vehicle front light device, in particular to a mounting structure of a light source for vehicle lighting fixtures such as front lights of four-wheeled motor vehicles and two-wheeled motor vehicles. Background technique [0002] There are PH-7 and PH-8 types of halogen bulbs as headlights for motorcycles. The shapes of the lamp holders 4 of PH-7 and PH-8 are different. In addition, the only difference between PH-7 and PH-8 is that the filament of PH-7 is set at the position of 20±0.3mm in front of the lamp holder. The PH-8 filament is set at a position of 28.5±0.3mm in front of the lamp holder. [0003] like Figure 5 As shown, PH-7 and PH-8 are respectively provided with filaments (filament) 11 and 12 at the center position in the Z direction and the position in the Y direction 2.5±0.4 mm away from it. By switching these two filaments, the central filament 12 can be used as a high beam for illuminating the distance ...
