Car headlights

Abstract

To solve such a problem that on roads with rainy nights and with few street lights, it is difficult for a driver to see a stop line on a road surface and to perform front confirmation of cars, and therefore, it is the best to drive with a car on high beams, but the intensity of the headlights from oncoming cars is strong, the driver who saw the light in his eyes becomes mentally disturbed, and there is a risk of operating a handle incorrectly.SOLUTION: In the present case that high beams of left and right headlights are simultaneously lit, an electric circuit is changed so that if one radiates high beam and the other radiates low beam. When raising a car's headlights to a ceiling, stop lines on wet roads can be easily seen, and by covering front of electric lamps with a movable cover, the glare caused by headlights can be reduced.SELECTED DRAWING: Figure 1

Description

[Technical field]

[0001] This invention improves the brightness of the light emitted forward by the high and low beams of the headlights in order to make nighttime driving safer and more comfortable, thereby not only increasing the driving safety by widening the driving field ahead of the vehicle driven by the driver at night, but also preventing the driver from losing his / her field of vision and making a mistake in steering when the light source of the headlights of an oncoming vehicle hits his / her eyes during nighttime driving in the rain, etc., thereby preventing a tragic head-on collision accident caused by the light from the headlights. [Background technology]

[0002] In order to make it easier for the driver to see far ahead from their line of sight, the brightness of the power bulb attached to the bottom of a car's headlights is increased, and when the high beam is turned on, it illuminates the road ahead at an angle almost horizontal to the road surface.

[0003] Headlight bulbs have also been replaced with LED bulbs to increase illumination at night, and multiple bulbs are now used instead of the previous single bulb to increase brightness.

[0004] Fog lights under the hood provide additional lighting to brighten the road ahead on dark nights, such as when it is raining, but this device is not very effective for night driving because the light it provides is short in distance.

[0005] Currently, there are only two ways for headlights to project light: high beam and low beam. When driving in mountainous areas with cliffs or on roads with few streetlights, there are many dark areas, which limits the driver's visibility and the light from illuminating all areas, increasing the danger.

[0006] [Patent Document 1] Patent application 2018-135749 [Patent Document 2] Patent application 2014-44392 Summary of the Invention [Problem to be solved by the invention]

[0007] In order to make nighttime driving safer, headlight bulbs that illuminate the road ahead have been replaced with LED bulbs and other devices to increase brightness in recent years. However, when a driver is hit by the light from an oncoming vehicle while driving, the strong glare of the headlight light source can cause eye pain and a heavy head, and this mental strain can extend to the entire body while driving, reducing the driver's ability to pay attention to steering, leading to a high incidence of rear-end collisions. As the danger of driving increases when light is received by the eyes in this way, this project aims to reduce the dazzle caused by the light from oncoming headlights and reduce accidents. In Patent Application No. 2018-135749, the cover for the headlight power bulb is fixed. The fixed type cannot adequately handle two-stage switching.

[0008] The Japan Traffic Safety Association encourages driving with high beams in order to reduce accidents at night, but as mentioned above, if the light hits the drivers' eyes they will become blinded, which has the negative effect of making driving less safe. Therefore, the wiring will be changed to improve the high beam illumination to only one side.

[0009] In order to brighten the front of the car on dark nights, such as when it is raining, fog lights are installed on both sides under the hood and, when turned on, illuminate the front. However, the fog lights only illuminate the area below the car, and a separate light source is used to illuminate the area.

[0010] On rainy nights, for example, when headlight light hits the surface of water that has accumulated on the road, the light reflects off the surface of the water, acting as a mirror, making the stop lines and center lines painted on the road completely invisible. This product prevents this phenomenon. [Means for solving the problem]

[0011] Currently, the headlight lighting format is such that both the high beam and low beam are turned on simultaneously in a horizontal line, but by improving the electrical circuitry so that the high beam and low beam are turned on alternately, and the alternating headlight lighting format can be selected when driving in cities or on narrow roads, the driver will be able to drive at night safely and with less mental fatigue, and will also be less likely to cause inconvenience to oncoming vehicles and others with the light from their own car's headlights.

[0012] In recent years, headlights have become brighter, and when the light from these lights hits the eyes of oncoming drivers or pedestrians in front of the car, it is as if a spotlight was pointed at their face, completely blocking their vision and creating an extremely dangerous situation. The cover plate of the headlight bent in an L-shape and placed on the ceiling is made movable according to the lighting state of the high beam and the low beam, thereby making it possible to suppress the oblique irradiation of the headlight by the cover plate and the glare caused by the light above the light source.

[0013] On dimly lit roads with few street lights or on dark winter nights, the light from fog lights mounted under the hood only illuminates a short distance in front of the vehicle's feet, making it ineffective when drivers need to check what is in front of the car while driving at night. As a means for supplementing brightness, a device having the function of a headlamp is provided in front of the side mirrors attached to both sides of the car, and an auxiliary additional light device is provided which is inclined as a whole so that the position where the light reaches is at the distance of the low beam.

[0014] When a lot of rain accumulates on the asphalt and creates a water surface, the light from car headlights at night reflects off the water surface, making it impossible to see the stop lines and center lines drawn underneath the asphalt. Currently, this phenomenon occurs because the light from headlights shines from underneath the vehicle, below the driver's eye level. If the headlight light is instead moved above the driver's eyes, onto the roof of the car, when the headlight light reflects off a rain-soaked surface, the light will be reflected upwards, and when the driver's eyes land on the white lines drawn below on the road, the reflection will be reduced and stop lines and other objects will be easier to see. Effect of the Invention

[0015] When car headlights are raised to the ceiling, the protective cover in front is less likely to become dirty with exhaust fumes and dust, and the light intensity at night is not reduced, reducing accidents and leading to safer driving. Also, since the bonnet equipment area is no longer located at the front, that length can be converted into the driver's seat, creating more comfortable space. The headlights shine from the ceiling, and the way they reflect light onto the road ahead is different from previous models, which reduces the mirror-like effect on wet roads and makes stop lines and center lines more visible.

[0016] By alternating between the high beam and low beam of the headlights, with the low beam facing the center line of the road and the high beam facing the pedestrian side, there is no illuminating the oncoming vehicles, safe driving at night can be continued, and the driver's mental fatigue is reduced.

[0017] If a curved, L-shaped light covering plate is attached to the front of the headlight bulb and made movable up and down by an electromagnetic device powered by a battery, the upper part of the light source in the case of high beam and low beam can be covered with a cover to reduce the amount of light projected onto the bulb, thereby reducing the glare received by people standing in front of the headlight.

[0018] The light from fog lamps does not provide sufficient brightness for driving on dark roads at night. By installing headlamps in front of the side mirrors on both sides of the vehicle and aligning the light source pointed diagonally toward the side mirrors with the position of the low beam, there is an advantage in being able to drive on bright roads at night in a way that was not possible before. By using a fixed, L-shaped light cover plate to reduce the leakage of light from the upper part of the light bulb, it is possible to suppress the glare caused by the light of people or vehicles in front, thereby reducing the number of accidents.

[0020] This device reduces automobile accidents caused by electric circuit diagrams, which has the feature of improving the headlight light irradiation method so that the headlights of an automobile can be easily illuminated in the dark at night and the driver is not dazzled by the headlights of the automobile in the oncoming traffic. There are two confusing points in this electrical circuit diagram. In the circuit diagram in Figure 7, the SWL low beam and SWH high beam do not light up at the same time. There is an interlock in place between operating the low beam with the knob on the lever next to the handlebars and switching the high beam up or down on the lever itself. Another thing is that the SWO select switch has a 2A2B contact structure, and the O point is always connected regardless of whether it is switched between L and R, forming a high beam configuration.

[0021] From the front view parts layout diagram in Figure 1, the electrical wiring from the battery 7 to the left and right headlights 1 installed on the ceiling of the car, the central infrared objective sensor 0, and the front panel 8 that operates the side mirror headlights R1 and R2 are represented by 4. The wiring from the battery to the ceiling is passed through the reinforcement on the side of the windshield, and the drain pipe from the ceiling is also placed inside. Ventilation holes 5 are placed on the ceiling to prevent the temperature from rising.

[0022] In the side view 2 of the headlight installed at an angle on the ceiling, the L-shaped cover 2 of the bulb 3 is connected to the rotating shaft 11 via the field plate 10. When the headlight is set to high beam, the electromagnetic coil 9 works, and when the headlight is set to low beam, the electromagnetic coil 12 works to move the front of the bulb up and down to adjust the amount of light on the upper side of the headlight ceiling in two stages for high beam and low beam irradiation.

[0023] FIG. 3 shows a ceiling headlight cover 2 which reduces the light at the top of the headlight by means of a field plate 10 operated by an electromagnetic coil of 12 low beam or 9 high beam on a rotating shaft 11.

[0024] Figures 4 and 5 show a headlight device installed in front of the side mirror. A fixed cover bent in an L-shape from the top of the diagonally installed lamp 3 illuminates the area that will become the vehicle's low beam, brightly lighting up the road ahead at night. The wiring runs from the side mirror mounting bracket through the body of the vehicle, via the front operation panel, to the battery.

[0025] FIG. 6 shows an operation panel 8 attached to the bonnet of the driver's seat. SWO is a three-notch select switch that, when switched between R and L, alternates between left and right high and low beam illumination. The PB is an on / off push button switch that activates an infrared object detector mounted on the ceiling. When it detects an oncoming vehicle in front of the vehicle, it automatically switches the headlights to low beam to reduce glare caused by the light.

[0026] Figure 8 shows a headlight 1 mounted at an angle on the ceiling of a car. If the focal point of the high beam and low beam in front of the car is Xm, the upper light can be suppressed by a headlight bulb cover 2 up to an angle of α degrees that appears there. This feature features headlights raised to the ceiling, but the only drawback to this feature is that it reduces glare.

[0027] Figure 7 shows the electrical wiring diagram for alternating high and low beam headlights on the left and right. When an obstacle appears in front of the car, the infrared object detector automatically switches to low beam. When the handle lever knob switch SWL is turned on from a DC battery power source, both the headlights on the ceiling and side mirrors turn on their low beams and the dimming cover LC also functions at the same time. By setting the SWH and SWO switches to O, the headlights on the ceiling will become high beam, and the high beam dimming cover HC will reduce the light above. When SWO is set to the L side, relay X1 is activated and the left high beam and right low beam of the ceiling headlight are alternately illuminated. Switching it to the R side will have the opposite effect, and the relay X2 will illuminate the front by alternating between the left low beam and right high beam. The circuit for lighting the forward-facing low-beam of a car is designed to light both the ceiling and side mirrors simultaneously, but by changing the circuit and using one of them as a supplementary device, it is possible to adjust the amount of light in the front at night. When PB is inserted, the infrared object detector is activated and all headlights are lowered to low beams. This automobile headlight device makes driving at night safer in the dark and eliminates the driving mistakes caused by headlight glare on oncoming vehicles, thereby contributing to Article 1 of the Traffic Act on Japan's narrow roads. Such new technologies also have the potential to revitalize economic activity, which has been stagnant due to the COVID-19 pandemic, and will spread the use of Article 1 of the Patent Act.
