most bulbs are fixed with wire springs. Shaking the wire springs left and right will release, and then you can pull out the lamp holder. At this time, you must check the power of the bulb again. Halogen bulb is a small cylindrical glass tube. When taking a new bulb, remember not to touch the surface of the glass with your hands, otherwise the grease on the glass will cause the temperature of the bulb to rise sharply when it is powered on, causing the bulb to break. There are several locating pins on the bulb base. Insert the new bulb into the original position, make sure that the bulb will not loosen, and then restore the whole headlamp to its original shape in the reverse order of disassembly. After that, you can go back to the driver's seat, turn on the headlight switch and enjoy your labor achievements

as a result, the bias voltage is not applied to the base of the first switching transistor Tr1, and the conductivity between the emitter and collector of the first switching transistor Tr1 is also turned off. Therefore, when the ignition switch ign is off, the instrument power supply (power supply 1) 1 is not connected to the indicator light (LED) 3, and the indicator light (LED) 3 is not lit by the instrument power supply power supply 1) 1. In addition, when the + B power supply (continuous power supply) not shown is not connected, the current does not flow through the diode D2, the protection resistance R6 and the signal line 9 of the indicator lamp (LED) 3 Therefore, when the + B power supply (continuous power supply) not shown during the ignition switch ign off state is not connected to the signal line 9, the indicator lamp (LED) 3 is not on. At the same time, when the + B power supply (continuous power supply) not shown during the advantages of our testing machine equipment in the ignition switch off state is connected to the signal line 9, the current flows through the diode D2, the protection resistance R6, and the indicator light (LED) 3 Therefore, even in the off state of the ignition switch IGN, it is not shown that this is because the + B power supply (continuous power supply) with large deformation and no fracture when the low-carbon steel is pressed is also connected to the signal line 9, and the indicator light (LED) 3 is lit by the + B power supply (continuous power supply) of the vehicle. For many years, suppliers and automobile manufacturers in the automotive industry have been committed to the research of lamps with dynamic lighting, high-resolution and accurate lighting effects. China's technology is slightly backward and does not affect other road users

it is easier to replace the bulb of the auxiliary lamp, which is usually removed from the rear of the lamp. The bulbs of most signal lamps are fixed on a base plate, which can be easily removed with a screwdriver. If it is a rear lamp, remove the interior trim panel of the luggage compartment first. The bulb of the auxiliary lamp is generally a spherical incandescent lamp, and the fixing method is the right angle plug-in lock type commonly used in our home. Like headlights, remember to replace bulbs with the same wattage. Every car has a generator. When the engine is running, it drives the generator to work. Through the voltage regulator, the excessive difference of voltage at different speeds is balanced, and then through the rectifier, the alternating current is changed into direct current, which is sent to the battery for charging and storage. This process is automatic, so there is no need to charge the battery additionally. As for the automobile air conditioner, it is directly driven by the engine machinery, so there is no need for battery power supply

some people think that turning on the fog lamp will sway to the car in front. In fact, as long as your fog lamp is reasonably designed, this situation will not occur, because the fog lamp itself is not designed for lighting, and their beams are very scattered, so it looks very bright but will not dazzle. Turn on the rear fog lamp when the rain is very, very heavy, because our red tail lamp itself has very good penetration, and the general heavy rain can not block its light. The brightness of the rear fog lamp is very high, which is used to penetrate the thick fog. It is easy to shake the rear car when it is used in general rainy days. If the sight of the driver behind is affected, then our own safety can not be guaranteed. The so-called "double flashing" is the hazard warning light. Every car has it, and the switch is two triangles set together. The abuse of double flash is quite common in China. In fact, it should only be used in very dangerous situations, such as an accident ahead, or you need to stop temporarily on the main road. Generally, we should not use it during driving. If we abuse the double flash, it is likely to send wrong information to the surrounding vehicles, resulting in danger. The OLED tail lamp of Audi A8 adopts a through design, which gives people a strong sense of mobility. After it is lit, the recognition degree is also very high. The public resentment that the Audi tail lamp is blind has been weakened a lot

the car battery is charged by this small generator. Moreover, it is not impossible to charge the battery. For some low-level cars, if you don't put the key for a night, you can start it the next day. You can't start a fire without charging. Power electronics technology is a discipline that studies power semiconductor devices to realize power conversion and control. It is a new frontier discipline that electronics, power semiconductor devices and control intersect with each other. Its research content is very extensive, mainly including power semiconductor devices, magnetic materials, power electronic circuits, control integrated circuits and power conversion devices composed of them. When the engine of the car is running, it drives a small generator, which provides electric energy for all electrical equipment in the car (except for air conditioning, which is the engine that directly pulls the refrigeration compressor). Some hybrid electric vehicles, such as Toyota Prius., There is a braking force feedback system, that is, when you need to slow down or brake, you force the transmission shaft to drive the generator, converting the kinetic energy of the car into electric energy, which plays a role in saving energy

therefore, considering the base potential of the pull-up switching transistor, the switching transistor is turned on even if the signal line becomes disconnected due to disconnection or poor connection. In this case, when the ignition power supply (instrument power supply) connected to the instrument unit is used to pull up the power supply when the ignition switch is on, the base potential of the switch can pull up the transistor to illuminate the indicator light when the ignition switch is on. In other words, even if there is no disconnection or poor connection in the signal line, the indicator light cannot be turned on during the ignition switch off state. Therefore, it is considered that the base potential ignition switch of the switching transistor is biased by supplying the current from the continuous power supply (+ B power supply) to the feed circuit of the indicator lamp in the off state. In this case, the + B power supply is connected to the feed circuit of the indicator without passing through the ignition switch. Therefore, even when the ignition switch is off, if there is no disconnection or poor connection in the signal line, the indicator light can be turned on, so as to ensure that we can absolutely meet the technical indicators of the experimental machine. In fact, this is not the first time we have heard about Volkswagen's future lighting plan. When the Volkswagen zzion concept car was unveiled for the first time, the automaker proposed a lamp technology that simulates the human eye

the car battery is charged by this small generator. Moreover, it is not impossible to charge the battery. For some low-level cars, if you don't put the key for a night, you can start the car the next day. You can't start the car without charging. The power required by the lighting system of the car is directly supplied by the battery. The power source process of the battery is as follows: when the engine is running, drive the generator to work, and balance the excessive difference in voltage at different speeds through the voltage regulator, Then through the rectifier, the alternating current is changed into direct current, which is sent to the battery for charging and storage, and this process is automatic. (except for air conditioning, which is a refrigeration compressor directly pulled by the engine) the automobile circuit is divided into ten systems: power supply system, starting system, ignition system, lighting system, signal system, instrument and alarm system, auxiliary electrical system, engine electronic control system, automobile chassis electronic control system, automobile air conditioning system. The circuit system and computer of the car are hidden in the car body, which are not easy to see. When the engine of the car is running, it drives a small generator, which provides electric energy for all electrical equipment in the car (except for air conditioning, which is the engine that directly pulls the refrigeration compressor). Some hybrid electric vehicles, such as Toyota Prius., There is a braking force feedback system, that is, when it is necessary to slow down or brake, it forces the transmission shaft to drive the generator, converting the kinetic energy of the car into electric energy, which plays a role in energy conservation

this lighting system can also help drivers pass dangerous mountain roads, because virtual lane signs will bend as the road turns

high strength car structure, bumper, thickness of car body steel plate, number of airbag, etc. can reduce the damage to a low degree in case of vehicle accidents. ABS anti lock, brake force distribution (EBD, etc.), brake assist (EBA, etc.), traction control (ASR, etc.), body stability control (ESP, etc.) these active safety features have become the focus of attention of vehicle users. However, when we pay attention to these vehicle safety equipment, we may overlook the role of vehicle lighting in safety. Many people seem to only notice the decorative and fashionable nature of the car lights, and even interpret the car lights from the point of view that the car lights can light up. They ignored the great effect of the lights on safe driving. Data from OSRAM, known as a German lighting expert, shows that 60% of traffic accidents occur in the evening, while 22% of traffic accidents occur when drivers are unable to see clearly
