Creation Instructions (1) [Technical Field of New Type] A lamp control device with anti-glare function, especially one applied to a vehicle, which can automatically turn on or off the lighting source and automatically switch the lighting when it can sense external light. Source, and anti-glare lamp control device for anti-glare operation. [Previous technology] Usually drive in the evening or when the weather is inadequate. Many car drivers do not turn on the lights, but at this time the outside light is dim and the sight is poor. It is easy to affect driving safety and cause traffic accidents. . Furthermore, if there is lighting equipment in the tunnel when passing through the tunnel, but the light is still insufficient, it is best to turn on the lights to ensure driving safety, but sometimes forgetting to turn on the lights due to negligence may cause traffic. accident. At the same time, when entering the underground parking lot, although the parking lot is equipped with lighting equipment, like a tunnel, the lighting is usually insufficient. Therefore, if you enter the underground parking lot without turning on the lights, you may not immediately notice that there is a collision with the oncoming car, especially in the corners. In addition, the number of accompanying vehicles continues to increase, causing the driving environment to deteriorate, especially when driving at night or in a low-light environment. The strong light from the rear of the car often illuminates the rear-view mirror, causing the driver to Reflective light or glare makes it impossible to clearly see the road conditions, which affects driving safety. Therefore, when driving at night or in a low-light environment, the driver must switch the high beam to the low beam in time to avoid affecting the oncoming car. However, after switching to the low beam, the area of the area illuminated by the low beam is small, resulting in

17626 Zhang Jiarong.ptd Page 5 M250832 V. Creative Instructions (2) The driver has a shorter and shorter field of vision in front. At the same time, if there is a condition on the road ahead, it is impossible to make an immediate discovery and response due to the speed of the vehicle, which may result in a traffic accident. Therefore, the driver is tired because the driver must frequently switch lighting sources such as front lights. In order to solve the troubles and inconveniences caused by car drivers who must frequently switch the distance of the front lights at night, or the front lights affect the driving safety of the front car, US Patent No. 5, 8 3 7, 9 9 4 is disclosed A control system for automatically darkening front lights of a vehicle. As shown in FIG. 5, US Patent No. 5, 8 3 7, 9 9 4 is connected to a microprocessor 60 and connected to an image sensing module 61, and the image sensing module 61 is based on an image. It is composed of a sensor 61a and an A / D converter 61b. The microprocessor 60 is connected to a controller 6 2 as a feedback control image sensing module 6 1 and a headlight control unit 6 3, and the headlight control unit 6 3 is connected to a headlight 6 4 〇 In this way, the image sensor 6 1 a of the image sensing module 6 1 can be used to detect the front lamp or the rear lamp of the oncoming vehicle, and the image sensor The analog signal of 6 1 a is transmitted to the A / D converter 6 1 b into a digital signal; then it is transmitted to the microprocessor 60; the signal input to the microprocessor 60 is then fed back by the controller 6 2 To the image sensing module 61, and the image sensing module 61 is controlled in a feedforward manner; the microprocessor 60 is then transmitted to the front lamp control unit 6 3, so that the front lamp control unit 6 3 Control the intensity of the front lights 64. However, the sensor used in this case to sense the brightness of lights coming from the front or front car is an image sensor, although the image sensor

17626 Zhang Jiarong.ptd Page 6 M250832 V. Creative Description Quality has advantages ’But relatively speaking, image sensors are relatively expensive to manufacture. Therefore, 'the manufacturing cost of this conventional technique is high' and the cost of installation and use will be increased for consumers. At the same time, the image sensor 6 1 a of the conventional technology, which is a vehicle traveling through streets and lanes, is prone to dust and reduces the sensitivity of sensing. Moreover, the image sensing module 61 must feed forward through the controller 62, so it will increase the complexity of the control structure 'and increase the manufacturing cost', which will relatively increase the sales price and reduce consumers' desire to choose. In addition, the image sensor 6 1 a can only sense the light source of the vehicle in front to control the illuminance of the front lights, but it cannot sense the light of the front lights of the rear vehicles to prevent the rear vehicles from shining in the rear view. The reflected light caused by the mirror causes glare to the driver, so it is not perfect in use and needs to be improved. In order to solve the problem that the reflected light caused by the rear vehicle shining on the rear-view mirror causes glare to the driver, China's Patent Publication Nos. 4 959 6 0 and 4 1 602 have proposed solutions respectively. China Patent Bulletin No. 4 5 6 7 0 discloses an automatic anti-glare (Ant i-Glare) module, which is provided with a liquid crystal panel, a light sensing element, and a control module in a vehicle rearview mirror. The light sensing element senses light and outputs a corresponding light intensity signal. After receiving the light intensity signal, the control module determines whether a voltage is applied to the liquid crystal panel to make the liquid crystal panel opaque or transparent. This prevents glare. China Patent Bulletin No. 4 6 14 2 discloses a rearview mirror for vehicles with display function and light sensing automatic anti-glare.

17626 Zhang Jiarong.ptd Page 7 M250832 V. Creative Instructions (4) 45 9 6 70 Patent is provided with a reflective film on the back of the liquid crystal panel, so that when the liquid crystal panel can transmit light, the reflective film reflects toward the liquid crystal panel The light 'makes the LCD panel reflect the image like a mirror. However, although Chinese Patent Publication Nos. 4 5 967 and 4 6 142 have the effect of preventing glare, these patents cannot simultaneously solve the problem that car drivers must always switch before driving at night. The trouble and inconvenience caused by the distance of the headlights, or the problems caused by the influence of the front headlights on the driving safety of the front car 'still need to be improved. Therefore, how to effectively solve the problem of how to switch the distance between the front lights and the glare caused by the rear vehicles shining on the rearview mirrors is an urgent issue. [New content] In view of the above-mentioned shortcomings in the conventional structure, the main purpose of this creation is to provide a car light control device with an anti-glare function. Its visual ring controls the distance of the lighting source and turns it on and off. Switch and prevent glare to maintain driving safety.

Creation instructions (9) Accept the control signal from the control circuit 10 to polarize the drive of the anti-glare module 30, so as to avoid being affected by the strong light coming from the car behind driver. The headlight control module 40 is composed of a headlight control circuit 41 and at least two lighting sources such as a front headlight 42. The lamp control circuit 41 is used to control the movement of the front lamp 42. Of course, the vehicle light control circuit 41 can also choose to control the actions of other lighting sources, and has functions such as delay, so that the vehicle light control module 40 has a control function that can be used to delay shutdown. When the light sensor 2 a for sensing the light in the front senses a signal from the outside light output corresponding to the light intensity, and the control circuit 10 receives the signal from the light sensor 20 a and judges the When the signal strength is lower than a predetermined value or exceeds a predetermined value, the control circuit 10 sends a corresponding control signal to the lamp control circuit 41 of the lamp control module 40, and thereby controls the front lamp 4 2 distance switch. The lamp control module 40 can be used not only to control the distance of the automatic switching lighting, but also to control the lighting source such as the front lamp 42 to be turned on and off. For example, when the signal strength from the light sensor 20a is lower than a predetermined value, it may be, for example, when the external light is too dark or inadequate, such as in weather haze, dusk, entering a tunnel or underground In the parking lot, the corresponding control signal generated by the control circuit 10 receiving the signal from the light sensor 20a causes the lamp control circuit 41 to turn on the front lamp '42. Therefore, the front headlight 42 can be automatically turned on in the case of too low or insufficient light. Conversely, when the signal strength exceeds the predetermined value, it may be the case where the external light is strong, for example, in the day when the sun is shining, or by a tunnel or underground.

At the same time, when driving the car's headlights 4 2 at night, the light sensor 2 0 a for sensing the light in front can sense the light of the headlights of the oncoming vehicle or the taillights of the front vehicle. , And output a signal corresponding to the light intensity, and the control circuit 10 receives a signal from the light sensor 20 a, and when determining that the signal intensity exceeds a predetermined value, sends a corresponding control signal to The headlight control circuit 41 is instructed to switch the front headlight 4 2 from a high beam headlight to a low beam headlight. In this way, you can avoid causing glare to the oncoming or ahead vehicles, and can automatically control the distance of the front lights, so as to solve the problem caused by the driver must manually and often switch the distance of the front lights in the conventional technology Trouble and inconvenience. Moreover, after the oncoming vehicle is far away, or the distance from the preceding vehicle is extended, or after the preceding vehicle has been exceeded, the control circuit 1 0 is caused by the light sensor 2 a cannot detect strong light. The received signal strength does not exceed the predetermined value. In this way, the corresponding control signal sent by the control circuit 10 causes the headlight control circuit 41 to switch the front headlight 4 2 from a low-beam headlight to a high-beam headlight, thereby providing a wider field of illumination. . In addition, when the vehicle is waiting for the red light to change to a green light, the two vehicles are very close. Even if the rear vehicle turns on the high-beam and low-beam lights instead of the high-beam light, it will make the vehicle in front drive very much. Uncomfortable. At this time, a set of light sensors (not shown) can be added to detect the distance to the vehicle in front.

Therefore, in addition to providing automatic switching of the near and far lights during travel, the lamp control device of this creation can also automatically sense and switch the size lights when waiting for parking. In addition, according to the design, the headlights can also automatically adjust the strength / light / darkness and size of the headlights as the current, voltage, or resistance changes, rather than just the design of the distance, switch, size, etc. Compared with the conventional technology, the anti-glare headlight control device of this creation can not only provide automatic sensing and switching of large and small lights while waiting for parking while traveling between near and far lights, but also have With the change of the current, voltage, resistance, etc., the headlights of the lights are automatically adjusted. Therefore, by applying the light control device with anti-glare function of this creation, the front lights can be automatically turned on or off when driving at night, so as to avoid the trouble and inconvenience of manual operation, and provide automatic switching of the distance, switch, strength and weakness of the lighting. / Light control device with anti-glare function that can automatically change the lighting state of the lighting source, and can increase driving safety. It can be seen that the anti-glare headlight control device of this creation can automatically turn on or off the front headlights by sensing external light, or automatically switch the high-beam headlights to the low-beam headlights by sensing the lights of the oncoming cars. , And can sense the light coming from the rear to polarize the rearview mirror, not only control the distance of the front lights depending on the environment
