Locomotive high-intensity discharge lamp and low beam automatic switching system

This creation relates to a locomotive light automatic switching system, in particular to a locomotive high-intensity gas discharge lamp and a low beam automatic switching system.

At night, the driver must rely on the locomotive headlight system to clearly see the people, things and things in front, so the presence and use of the locomotive headlights is very important. Some drivers lack the concept of switching the timing of the near and far lights of the locomotive headlights. In general, in the absence of a car, the high beam is easier for the driver to see the things ahead than the low beam, allowing the driver to react ahead of time to ensure safe driving; while in the car or following At the time, it is safe for the driver to hit the low beam without making the opposite car or the front car glaring. In view of the fact that some drivers often neglect the switching timing of the near and far lights, there is a need for an automatic switching system for the locomotive lights that can automatically switch far and near light.

Looking back at the conventional technology, the Republic of China Patent No. M394257 discloses a vehicle lamp near and far switching structure. The structure includes a cover having a through hole and an illuminant disposed in the through hole. a switching mechanism is disposed at a position in front of the through hole, and the switching mechanism includes a fixed shutter, a movable shutter, and an actuating body, and the fixed shutter is fixed in a vertical position in front of the through hole of the cover body, and the fixed shutter can be The occlusion corresponds to the transmissive area of the through-hole portion, and is disposed at a position above the center. Reduce the notch of the occlusion area. The movable shutter is disposed in parallel with the fixed shutter, and has a shielding portion and a joint portion at the two ends, and the shielding portion can block the notch portion of the fixed shutter; the moving body is engaged with the movable shutter, and can move the movable cover. The plate displacement covers or does not cover the notch to form a near-light or a high-light mode.

The foregoing technology has the advantage of simple operation, and controls the amount of light emitted from the locomotive headlights, especially the high-intensity discharge lamp (HID), to achieve near-far light switching. However, the aforementioned functions are not automated and do not allow the driver to concentrate on driving without having to be distracted by the switching of the near and far lights. In addition, this technology cannot effectively control the amount of light due to the use of a single light source, but it is easy to cause the illumination of the headlights to be uncomfortable for the driving of the headlights, thereby causing danger of driving.

Therefore, the new creator has developed the locomotive high-intensity gas discharge lamp and low beam automatic switching system to solve the above problems.

The manual switch 900 can force the hood 500 to shield one of the low beam 200 or the high intensity gas discharge lamp 400. When the manual switch 900 is turned on, the hood 500 shields the light emitted by the low beam lamp 200. Conversely, when the manual switch 900 is turned off (as shown in FIG. 2), the hood 500 shields the light emitted by the high-intensity discharge lamp 400.
