Description

One-lamp dual-purpose automobile glare-free lighting system

Technical Field

The invention belongs to the field of automobile illumination, relates to an automobile LED headlamp illumination system, and particularly relates to an automobile glare-free illumination system with two purposes of one lamp.

Background

Automobiles have been used as vehicles with a wider and wider application range in daily life, and various technologies used in automobiles are also in the future. However, the lighting technology has not been substantially improved, and the vehicle headlamp is originally used for guaranteeing driving safety at night, but when two vehicles are opposite to each other, the lights of the two vehicles influence each other, and drivers of the two vehicles frequently step on a brake pedal due to unclear sight, so that not only the driving comfort is influenced, but also traffic accidents can occur due to slight negligence, and even if the opposite vehicle is changed into a low beam, the visual condition is not greatly improved when the vehicle lamp is bright and the vehicle type is large. Therefore, when the vehicle is driven at night, the light of the opposite vehicle is the most headache, the influence of dazzling light of the opposite vehicle is eliminated, and the visual condition of driving at night is improved.

To improve this situation, all countries in the world seek to try, but to date there is no ideal solution, and the current solutions can be summarized into three general categories: one is that the two parties automatically change into low beam illumination when meeting; the other is illumination with polarized light whose wave directions are perpendicular to each other; the third type is to selectively block the illumination range of the vehicle to avoid the eyes of the opponent driver. Although these solutions improve the visual condition of night driving, the disadvantages are also obvious: the automobile lighting device automatically changes into low-beam lighting, and can change into low-beam lighting when the light of the opposite side appears, so that the vision condition of the automobile is worse, the lighting range is suddenly reduced, the automobile lighting device cannot be well matched with the automobile speed, a driver cannot see the road condition ahead in time, and the hidden danger of driving accidents is increased; the polarized light illumination has relatively harsh use conditions, and the effect is not ideal due to the wave particle diphasic property and the optical rotation of the light; the illumination range is selectively shielded and illuminated, the requirements of different vehicle types and different lanes cannot be met, and the illumination distance and the shielding range cannot be considered at the same time (although some countries in recent years want to automatically control the size of the shielding range by using a computer, the result of the method is that the more objects in front, the larger the illumination blind area is, the more blind areas cannot be achieved during driving), and the illumination range has more blind areas.

In summary, the above solutions have not achieved the expected effect; this has also made improvements in automotive lighting technology one of the world-recognized challenges.

Furthermore, the light valve is an electrically controlled liquid crystal high-speed light valve (referred to as an electrically controlled light valve for short).

Furthermore, the electric control light valve can transmit light when not electrified; the electrically controlled light valve is opaque when energized.

Further, the photoreceptor 12 is arranged at an idle light-transmitting position in the automobile cab, the sunshade plate type electric control light valve 13 is arranged at a position (such as a position similar to the position of a sunshade plate) which can be moved to the front of the eyes of a driver when in use, or the glasses self-wearing type electric control light valve 13A can be carried about, and is connected with equipment through a socket and a flexible wire when in use.

Preferably, the light electronic information system 14 can be separately installed or can be designed into the whole vehicle circuit system of the vehicle.

Further, the time for the LED headlamp to emit light and not emit light is between 0.01 and 100 milliseconds, and the time for the electrically controlled light valve to be switched on and off is between 0.01 and 100 milliseconds.

The working principle of the invention is as follows:

the first condition is as follows: as shown in fig. 2, when a single vehicle is running, the oscillator 304 generates a vehicle cycle command signal, at this time, the signal selection inverter 204 randomly selects one of the 1 st input terminal and the 2 nd input terminal as an active input terminal, and if the 2 nd input terminal is initially selected as the active input terminal, the input signal is 0 (therefore, the single vehicle is running, there is no light on the opposite side, the photoreceptor 12 does not sense light, no light signal is output to the identification signal detector 202, the output of the identification signal detector 202 is 0, so the signal at the 2 nd input terminal of the signal selection inverter 204 is 0), the output of the signal selection inverter 204 is high level, the delay flip-flop 205 is not triggered, the output is 0, the 0 signal is fed back to the 4 th input terminal of the signal selection inverter 204, when the time of the 0 signal exceeds several tens of milliseconds, the signal selection inverter 204 will automatically select the 1 st input terminal as the effective input terminal, at this time, the input effective signal is changed into the periodic command signal of which the first half period is low level and the second half period is high level of the oscillator 304, and the signal is inverted by the signal selection inverter 204 and then output as the periodic signal of which the first half period is high level and the second half period is low level (signal a in fig. 2). This signal is sent to the delay flip-flop 205, and after a short delay (in the order of microseconds), the delay flip-flop 205 is triggered to be in a monostable state and outputs a high level, the monostable time is about half of the duty cycle (in the order of milliseconds), and the signal output by the delay flip-flop 205 is as shown in signal c in fig. 2. The signal is fed back to the 4 th input terminal of the signal selection inverter 204, the signal selection inverter 204 is released from its own force (but its current valid input terminal is not changed), the signal is also transmitted to the input terminal of the light valve controller 310, the electrically controlled light valve is controlled by the light valve controller 310 to periodically transmit light in the first half period and not transmit light in the second half period, the signal is also transmitted to the 1 st input terminal of the headlight controller 311, the headlight is controlled by the headlight controller 311 to periodically emit light in the first half period and not emit light in the second half period. If the signal selection inverter 204 starts to select the 1 st input terminal as the active input terminal, the input active signal is a periodic command signal with the first half cycle being low level and the second half cycle being high level, and the signal is inverted by the signal selection inverter 204 and then output as a periodic signal (signal a in fig. 2) with the first half cycle being high level and the second half cycle being low level, and similarly, the signal is sent to the delay flip-flop 205, and after a short delay (microsecond level), the delay flip-flop 205 is triggered to be in a monostable state and output high level, the monostable time is about half of the working cycle (millisecond level), and the signal output by the delay flip-flop 205 is as the signal c in fig. 2. The signal is fed back to the 4 th input terminal of the signal selection inverter 204, the signal is released from the forcing of the signal selection inverter 204, and the signal is simultaneously transmitted to the input terminal of the light valve controller 310, the electrically controlled light valve is controlled by the light valve controller 310 to periodically transmit light in the first half period and not transmit light in the second half period, and the signal is simultaneously transmitted to the 1 st input terminal of the headlight controller 311, and the headlight is controlled by the headlight controller 311 to periodically transmit light in the first half period and not transmit light in the second half period.

As described above, as long as the headlamp is used during driving of a single vehicle, the light electronic information system 14 always makes the electrically controlled light valve pass light through the first half cycle and do not pass light through the second half cycle in a cycle, and achieves a predetermined single vehicle illumination state that the headlamp is made to emit light through the first half cycle and not emit light through the second half cycle in a cycle, and with reference to fig. 3, illumination of the road by the headlamp and observation of the road condition by a driver are completed.

Due to the short time periods (in milliseconds) in the lighting state and the persistence of vision of the eyes of people, the lighting state does not affect the normal observation of the road condition by the driver and does not generate the flickering sense of the light.

Case two: when the two vehicles approach each other, the light sensor 12 senses the light of the other vehicle, and if the other vehicle is a vehicle of a general lighting system, the output of the identification signal detector 202 is still 0 because the identification signal is not detected, and the light electronic information system 14 controls the headlamps to operate in the above-mentioned single-vehicle lighting state as described above. Although the interference of the light of the other party cannot be eliminated completely, the electric control light valve 13 is closed in half of the time in one period, so that the influence of half of the illumination energy of the other party can be weakened; and because the own illumination energy is all concentrated in the first half period of opening of the electric control light valve 13 and is output by the headlamp, the second half period of closing of the electric control light valve 13 does not influence the own illumination intensity. This makes the lighting system reduce the influence of half of the lighting energy of the other party on the own party and greatly improve the vision of the own party driving at night under the condition of not influencing the lighting intensity of the vehicle.

If the other party approaches the vehicle with the same lighting system, the light sensor 12 senses the light of the other party and senses the identification signal in the light and transmits the identification signal to the identification signal detector 202, the identification signal detector 202 detects and shapes the identification signal and transmits the shaped identification signal to the 1 st input end of the selection controller 203 and the 2 nd input end of the signal selection inverter 204, the selection controller 203 compares the signal of the 1 st input end with the signal of the 2 nd input end (the signal of the 2 nd input end is the signal of turning on and off the own electronic control light valve, and is the signal c in fig. 2), when the high levels of the two signals are overlapped in time, the influence of the opposite side light exists (the larger the overlapping area of the high levels is, the larger the influence of the opposite side light on the own side is), at this time, the selection controller 203 outputs a signal for the signal selection inverter 204 to change the signal selection, the signal selection inverter 204 changes the effective input end from the 1 st input end to the 2 nd input end under the control of the signal, the high level of the input end signal represents the turn-on of the headlight of the opposite party, the low level represents the turn-off of the headlight of the opposite party, the opposite head lamp is turned on to be turned off and corresponds to the falling jump edge of the signal from high level to low level, this down-going edge is inverted by the signal-selecting inverter 204 to become an up-going edge (signal b in fig. 2) and output to the delay flip-flop 205, after the delay flip-flop 205 is briefly delayed (in microseconds) by the up-going edge, the triggering is a monostable state, the monostable time is about half of the duty cycle (millisecond), the delay flip-flop 205 outputs high level in the monostable state, and at this time, the signal output by the delay flip-flop 205 is the signal d in fig. 2. This signal is sent to the 2 nd input terminal of the selection controller 203, the 4 th input terminal of the signal selection inverter 204, the input terminal of the light valve controller 310, and the 1 st input terminal of the headlight controller 311, and at this time, the high level of the 2 nd input terminal of the selection controller 203 does not temporally overlap with the high level of the 1 st input terminal thereof, the selection controller 203 does not output the change selection signal, and the signal selection inverter 204 maintains the state, which is the operating state of both the vehicle-meeting vehicles of the same illumination system, as shown in fig. 4 and 5. Due to the influence of various discrete factors, the working states of the circuits of the two parties can be interchanged during meeting, that is, the party of the meeting can be the working state of the other party, and correspondingly, the other party is also the working state of the party of the meeting. However, no matter which pair of working states are matched automatically before the meeting, and once the state is determined, the state is kept unchanged in the meeting process until the meeting is finished.

As can be seen from fig. 4 and 5: when the vehicle meets, in the stage of time 0-1, the own headlamp 11 is closed, the own electric control light valve 13 is closed, the other headlamp emits light, and the other electric control light valve is opened. In this case, the opponent driver can observe the road condition with the light emitted from the opponent headlamp and the opponent driver is not affected because the own headlamp 11 is not illuminated. At the moment, the own electrically controlled light valve 13 is closed, so that the light of the other party is blocked, and the own driver cannot be influenced even if the light of the other party is not shielded. In the time 1-2 stage, the headlight of the opposite side is turned off, the electric control light valve of the opposite side is turned off, the headlight 11 of the own side emits light, and the electric control light valve 13 of the own side is turned on. In this case, the driver can observe the road condition with the aid of the light emitted from the headlights 11 of the driver and the headlights of the other party are not illuminated, so that the driver of the driver is not affected. And at the moment, the electric control light valve of the opposite side is closed, so that the light of the opposite side is blocked, and the light of the opposite side cannot influence the driver of the opposite side even under the condition of not carrying out any shielding. The illumination state for subsequent time periods repeats the above process periodically. In this state, even if both the drivers are on the high beam during the meeting, the drivers of both the drivers are not affected. At this time, both drivers feel that the headlights of the other driver are turned off, and only drive under the bright light of the drivers, and opposite objects and vehicles are clearly visible. Under the vision condition, drivers of two parties can easily and safely meet the vehicle, and the sight of the drivers is not unclear due to the light of the other party, so that the safety of meeting at night is ensured, and the driving at night is comfortable. The sight of the driver is clear, so that the use of brakes is reduced, fuel oil or electric energy is saved invisibly, the abrasion of the vehicle is reduced, and the time is also saved.

Case three: after the meeting is finished, because the photoreceptor 12 has no light irradiation, the output is 0, the output of the identification signal detector 202 is also 0, the signal of the 2 nd input end of the signal selection inverter 204 is 0, the output of the signal selection inverter 204 is high level, the delay trigger 205 does not trigger, the output is 0, the 0 signal is fed back to the 4 th input end of the signal selection inverter 204, when the time of the 0 signal exceeds dozens of milliseconds, the signal selection inverter 204 can automatically select the 1 st input end as an effective input end, and the input effective signal is changed into a periodic instruction signal of which the first half period of the oscillator 304 is low level and the second half period is high level. This signal is inverted by the signal selection inverter 204 and then outputted as a periodic signal (signal a in fig. 2) having a high level in the first half cycle and a low level in the second half cycle. After a short delay (in the order of microseconds) after the signal is sent to the delay flip-flop 205, the delay flip-flop 205 is triggered to be in a monostable state and outputs a high level, and the monostable time is about half of the duty cycle (in the order of milliseconds), and then the signal output by the delay flip-flop 205 is as the signal c in fig. 2. The signal is fed back to the 4 th input terminal of the signal selection inverter 204, the signal is released from the signal selection inverter 204 (but the current effective input terminal is not changed), the signal is simultaneously transmitted to the input terminal of the light valve controller 310, the electrically controlled light valve is controlled by the light valve controller 310 to periodically transmit light in the first half period and not transmit light in the second half period, the signal is simultaneously transmitted to the 1 st input terminal of the headlight controller 311, the headlight is controlled by the headlight controller 311 to periodically transmit light in the first half period and not transmit light in the second half period, and the signal automatically returns to the illumination state during the single vehicle driving, which is referred to fig. 3.

Case four: if a vehicle which is relatively driven exists in front after meeting is finished, the lamplight electronic information system can automatically repeat the control process of meeting the vehicle, and the expected effect of meeting the vehicle by two parties is achieved again.

It should be noted that the invention simultaneously considers two using modes and using effects. When a driver uses the sun-shading plate type electric control light valve or the glasses self-wearing type electric control light valve, the glare-free visual effect is shown; when a driver does not use the sunshade plate type electric control light valve or wears the self-wearing electric control light valve without glasses, the visual effect of common illumination is displayed. Both modes of use can be selected at the discretion of the driver.
