1228084 V. Description of the invention (1) [Technical field to which the invention belongs] The present invention relates to a vehicle headlamp device, and particularly relates to a light source installation structure for vehicle lamps such as front lamps of automobiles and two-wheelers. 0 [ Prior art] The halogen type lamp of a headlight for a wheeled vehicle is provided with PZ_γ and PH-8 plastic types. PH-7 and PH-8 only differ in the shape of the sleeve 4 and the position of the filament at pH-7 is set before the sleeve 4 2 ¡± 〇 · 3 followed by the position, and the filament of ρ η-8 The position is different from the position of 2 8 · 5 ± 0.3 mm in front of the sleeve 4. _ As shown in Fig. 5, at PH-7 and PH-8, the filaments 11 and 12 are provided at the center position in the Z direction and at a distance of 2 · 5 ± 0 · 4 mm from the Y direction. By switching these two filaments, the central filament 12 is used as a high-beam lamp for distant use from the relative position of the reflector not shown in the figure, and the filament 1 located 2.5 mm away from the center is used. 1 Used as a low-beam lamp for close use. In recent years, discharge lamps have been widely used in order to save power, high efficiency, and high color rendering (the effect of light sources that affect color and luster). This discharge lamp has a problem that there is only one place of the light emitting portion, and it is impossible to use the positional relationship between the reflector of the front lamp and the light emitting portion of the discharge lamp to obtain a high-light east and a light beam. The structure of the headlight lamp of the four-wheeler is also the same as the above-mentioned two-wheeler lamp. To solve the above-mentioned problems, for example, the invention described in Patent Document 1 is proposed.

The four-wheeler 'also makes it possible to obtain a high-beam and low-beam solution to the problem. The above purpose basically adopts the following records:-the first form of the light vehicle ΓΓ lighting device, which has a fixed position and chooses it; the seat of the lamp: the socket and fixed to the existing 矣 锊-Γ M, " ... VN% The socket of the socket shaft support lamp is rotated by a predetermined angle. The second form is characterized by being biased in a predetermined direction. The third aspect is characterized in that the member is sandwiched. In addition, the fourth aspect is characterized in that a permanent magnet is assembled on the rod-shaped member. [Performance method] The explanation of the best practice of the present invention will be described with reference to Figs. 1, 2, 3, and 4. Figs. Example 1 Example 2137-5979-PF (Nl) .ptd

The structure is a lever structure: the structure is characterized by ^: iron is installed in the socket, and at least one electromagnetic L is set near the μ member; the second hunter uses the electromagnet to attract the member to make the installation This discharge uses a biasing device to set two electromagnets facing the component. The component is a permanent magnet, or 1228084. 5. Description of the invention (4) Figures 1 to 3 show the example of the embodiment ^ The electric lamp 1 is inserted into the socket 3 And fixed. In the socket 3, the protrusions 5 on the left and right seats 3 and the sockets 5 and 4 = 7 are the holes where the protrusions 5 diverge. Therefore, insert ^ J slightly in the same direction as # 4. On the inner side of the kit 4, in order to insert, as part of the # 搵 Α 太 狄 / 1 > The thickness of the sleeve 4 is gradually changed in the vicinity of the crotch portion of the sleeve 4. The Li socket is provided with a lever-shaped member such as a rod-shaped member. In the case of "1 Benbei", the rod-shaped rod 6 is pressed into the socket 3 and inserted into the discharge socket :: and is fixed to the back side of the opposite side. In the cover 9 facing the γ direction: clothes electromagnet A 7 And the electromagnet B 8, the poles of electricity and 8 are arranged to sandwich the poles of the "electricity: iron" 4 and the electromagnet B. ^ Take the knowledge of Wu Wu b. Therefore, the end of the pole e It can move between the magnetic poles of the thunder magnet A 7 and the electromagnet b 8.
