A lamp is formed, and when the power of the solenoid valve is cut off, the operating means is restored to the original position by the elastic means, whereby the light shielding piece is engaged, the light shielding piece blocks the light beam below the light emitting means, and the light beam above the light emitting means. Only the light is retained and reflected by the reflector to form a near-light lamp, thus obtaining a ray change fixed to the far-light lamp.

Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a type of near-infrared lamp switching device, and more particularly to a near-infrared lamp with a fixed focal length under the condition that the distance between the light source and the shade reflecting surface is fixed using such a switching device. The present invention relates to a perspective lamp switching device that can generate light lamp switching, thereby achieving an effect that enables a driver to determine an accurate distance of an oncoming vehicle at night.

[0002]

[Prior art]

 In general, all headlights (commonly known as headlights) of vehicles have the function of switching between long-light lamps and near-light lamps, which meet the requirements of different driving road conditions.

[0003] The structure and switching method of the perspective lamp of the traditional illumination lamp is to provide two sets of filaments in one bulb, of which the first set of filaments is not shielded and the lower part of the second set of filaments is properly shielded. When the first set of filaments is selectively energized to emit light, there is no obstruction, so the emitted light is projected from all sides to the reflecting surface inside the shade, and then reflected by the reflecting surface. Projected to a relatively distant place. This is the effect of the far light lamp. Conversely, if the second set of filaments is selected and energized to emit light, a portion is blocked, so the emitted light is projected onto the reflecting surface in an unshielded direction and reflected by the reflecting surface. It is projected at a relatively close place, which is the effect of a near-light lamp.

[0004] The above-mentioned traditional bulbs already have a function of controlling a near-light lamp or a far-light lamp by using one bulb, but the brightness thereof is relatively low, so that a relatively high-grade car model is used. Uses a high-pressure discharge lamp (HID) with relatively high brightness as the illumination lamp. The so-called high-pressure discharge lamp has a structure that includes a light transmission discharge capacitor, is sealed in an impermeable manner, and is provided with a filler in the discharge lamp, and the filler is a metal compound and a rare gas. During normal operation, the metal compound evaporates and decomposes to form condensed metal xenon particles, which emit light by incandescent emission.

[0005] A high pressure discharge lamp can only generate a light source in a single sealed container, and therefore the bulb of the high pressure discharge lamp cannot switch between a far light lamp and a near light lamp. When used in automobiles, two sets of near-light lamps and two sets of far-light lamps need to be installed in front of the head of the car, and the high-pressure discharge lamps are expensive enough to be illuminated by consumers. The increased financial burden on lamps and the need to assemble a relatively large number of lighting lamps has impacted the standards that add even more added value to body space.

As a result, products for solving the above-mentioned drawbacks are provided in the public, and the technical means of this known product is to provide a lamp sheet in which a light emitting means is combined in a lamp shade, and the lamp sheet is provided. Connected to the solenoid valve, the energization of the solenoid valve or the operation at the time of power failure drives the lamp sheet and activates in the lamp shade, thereby altering the distance between the light emitting means and the reflecting surface inside the lamp shade, thus The effect of far and near lamp switching control is achieved using one light emitting means.

However, when the distance between the light emitting means and the lamp shade reflecting surface is different, the focal length of the reflected lamp light is also different, so that the reflected light is diffused due to poor focusing of the far light lamp or the near light lamp. There was a drawback that nighttime drivers could not accurately determine the true distance of oncoming vehicles, which easily caused an accident. For example, when the lamp was calibrated to produce an accurate focal length at the time of the near-infrared lamp during the manufacture of the lamp, that is, when the light-emitting means was moved so as to be closer to the reflecting surface, the focus was lost and the reflected light was blurred and diffused. Conversely, if the lamp is calibrated during manufacturing to have the correct focal length for the far-light lamp, that is, if the light-emitting means is moved further away from the reflecting surface, the focus will be lost and the reflected light will be lost. It has the problem of becoming ambiguous and spreading.

[0008] Therefore, the present invention has a problem that a conventional high pressure discharge lamp cannot switch between a far light lamp and a near light lamp using a single bulb, and also a conventional high pressure discharge lamp that switches between a near lamp and a near lamp. It is to improve the disadvantages of the device.

[0009]
