Whether it is standard or modified, as the most beautiful type of lights, LED lights are slowly gaining popularity. From Guangben Ling to the new lion run, to the Dongfeng Fengshen new S30 and other independent brand models, LED lights that were previously available in mid- to high-end models have begun to spread to low-end models.
Compared with traditional halogen lamps, LED lamps are more energy-efficient, environmentally friendly, and smaller in size, and they are flexible and easy to arrange, and can easily create a front-facing shape of a car. However, although LED lights are more dazzling and cool, their maintenance costs are also quite high compared to traditional lights.
LED lights into the mainstream of car headlights:The development of LED daytime running lights has actually been around for some years, but the models that were launched at the beginning were relatively high in price and not so popular. Xu Fan, a car-modified enthusiast, said that daytime running lights such as BMW and Passat are relatively good designs. Audi is also called "lighting factory" by the riders, "eagle eye", "sickle" and "lightning". It is a familiar LED lighting design for the riders.
In addition to being cool, daytime running lights ensure driving safety. Vehicles equipped with daytime running lights are more likely to be identified by the opposite vehicle in the event of daylight glare or poor visibility in rainy and foggy days. As a safety device, many countries in Europe have mandated manufacturers to match daytime running lights.
Guo Bo, the auto parts market of Hangzhou Auto City, said that LED lights are not only dazzling, but the brightness of all LED headlights even exceeds that of xenon headlights. The reaction speed is fast, but the price is relatively high, and the price ranges from 30,000 to 80,000. The original car configuration is only a few models of several luxury brands such as Audi and Mercedes, and there are fewer enthusiasts in the later stage.
Although the LED lights are dazzling, the high maintenance cost of the LEDs makes the owners call for "injury."
Recently, Hangzhou Cheyou Xiaolu is annoyed for the maintenance cost of his car BMW 3 series. Xiao Lu suddenly found out that the turn signal of the car was broken a few days ago. I went to the 4S shop for repair and found that the bulb was burned out. At the beginning, Xiao Lu didn't take it for granted. He thought that changing a light bulb would cost tens of dollars. "At that time, I thought I could get up to 200 yuan, but who would think, 4S shop told him that the repair cost was nearly 2,000 yuan." Xiao Lu annoyed He said that the maintenance worker told him that the LED turn signal could not be replaced by the lamp alone. If it is broken, the entire assembly must be replaced. There is no other way.
The new crown owner, Mr. Meng, has had the same experience. "At the time, the LED brake lights did not light up. When I went to the 4S shop, I asked for the entire assembly. The cost exceeded 1,500 yuan." Mr. Meng said inexplicably that he could not think of the price of the repair shop outside the same amount of more than 1,000 yuan. Think of the original old car to change a halogen bulb as long as tens of dollars, Mr. Meng said "can not afford to hurt."
"It's still good to change the turn signal or brake light. If it is a full LED headlight, the cost is 10,000 yuan." A small Japanese 4S shop circuit repairer Fu Xiaoding said that the replacement cost of an LED lamp assembly like the Audi A6L is close. 12,000 yuan.
Pay attention to the heat dissipation around the LED light:"The design and manufacturing concept of automotive electrical equipment such as lighting equipment has become more and more integrated, such as LED lights, air conditioners, CDs, etc." Xiao Ding said that the supply of this part of the accessories in the market is also developing towards integration.
Compared with traditional halogen bulbs, LED lamps theoretically have a longer service life and are more aesthetically pleasing, but because the normal operating temperature of LED lamps is below 60 ° C, and the car headlights are in use, or under high temperature exposure, LED lights The surrounding temperature will become very high, and the heat dissipation is not very fast. Once the temperature exceeds 60 °C, the operation of the LED lamp is not particularly stable, and even burns. "For the damage of most LED lights, all the lights will not be bright at once. Considering the high replacement cost of LED lights, the owner can replace the number of fault lights to affect the use effect, thus reducing maintenance costs. â€
The biggest factor affecting the lighting efficiency and life of LED cars is temperature. Therefore, owners who want to modify LED lights are recommended to choose LED lamps with good thermal conductivity, and pay attention to the heat dissipation of the surrounding environment of LED lamps in the future.
(1) After confirming the model number, it is best to ensure that the vehicle is turned off before starting to replace the headlights, and the car key is removed until the engine is completely cooled.
(2) Open the engine hood, simply replace the big light bulb. Generally, it is not necessary to remove the headlight assembly. The fixing method of different car lights is slightly different. Generally, there will be a dust cover at the end of the headlight. After opening, you can see the wire spring of the headlights, and you can take out the headlights with force.
(3) After removing the bulb, you can unplug the bulb from the power connector, and the action should be light to avoid breaking the power connector.
(4) Take out the new light bulb from the product packaging box, remember not to touch the glass part of the light bulb with your fingers, to avoid accidentally getting the wrong hand on the glass to affect its service life. It is best to wear gloves when operating, and Install the lamp on the power connector.
(5) Finally, fix the bulb on the wire spring and screw on the sealing cover.
In the car headlights, the shape of the lens head is the most standard, and there can be obvious bright and dark cutting lines to solve the problem of astigmatism. In foreign countries, xenon lamps are used as standard lenses, which belong to optical mirrors. Class, we call it "lens". The headlights with the lenticular head have the advantages of uniform brightness, strong penetrating power and small loss of light compared to the headlights using the conventional lamp head.
The lens heads of the vehicle are divided into two types: single light and double light. The single-lens lens is respectively designed with lenses corresponding to low beam and high beam, such as: M6 low beam lens, Mondeo high beam lens; the difference between the double light lens is that it can be transformed like far and low beam conversion. Usually it is a low beam state. When the high beam is turned on at the same time, it operates the dimming plate through the electromagnetic mechanism, so that the low beam light is also distributed to the high beam illumination, which is equivalent to two high beams together. Dual lens is generally used on medium and high-end cars, such as A6. BMW. Mercedes-Benz and so on.
Second, what is the angel eyeAngel eye - a kind of car light.
Angel eye headlights refer to the yellow or other color auras surrounded by low beam and high beam heads, which are beautiful in the state of the wide light. Mainly for decorative appearance and wide display, the colors are red, blue, green, yellow and purple.
Originally from the design of the BMW 5 Series headlights, when the headlights are turned on, the BMW headlights will have a halo. This aura is very similar to the aura on the angel's head, so many users have given her a nickname: Angel Eye. Under normal circumstances, the original "Angel Eye" headlights will be matched with the lens head and Xenon headlights. The angel's eye is divided into two types. (1) The cathode tube, material: glass, requires a starter, the brightness is very high, the appearance is beautiful, the life is long, the light-emitting part is uniform, and it can be clearly seen from that angle. (2) LED, material, light-guiding plastic, similar to BMW Angel Eye; general modification uses LED structure, so it is called angel eye LED aperture; but sometimes someone has the headlight assembly with the angel eye as the angel Eyes, or angel eye headlights, angel eye headlight assemblies, in fact, confuse the concept, the correct angel eye concept should refer to the angel eye circle.
Third, what is the angel eye headlight assemblyAngel eye headlight assembly, in fact, is a headlight assembly with an angel eye LED aperture, some with a lens without a lens, some with a single lens (mostly a low beam lens), and some with a double lens Installing it not only makes your car stand out in the sea, but also makes you more attractive. It can not only improve the illumination when you install Xenon headlights, but also improve the sight of night driving. The key is not to cause danger to others.
Fourth, what is called HID xenon lampXenon lamp is a new type of headlight containing helium, also known as high-intensity discharge gas lamp, referred to as HIDIntensityDischargeLamp. Xenon lamp broke the principle of tungsten filament light invented by Edison. The quartz lamp tube was filled with high-pressure inert gas - Xenon helium gas, replacing the traditional filament, with mercury and carbon compounds on the two electrodes, and 23000 volts through the ballast. The current stimulates the xenon to illuminate, creating a perfect white arc between the two poles, which emits light close to perfect sunlight.
The automobile HID xenon lamp is different from the traditional halogen lamp. This is a high-pressure discharge lamp. Its illumination principle is to use positive and negative electric stimulation to stimulate the reaction of helium with rare metal, so there is a small glass ball in the tube. It is filled with helium and a little rare metal. As long as the current is used to stimulate them to carry out chemical reactions, the two will emit light with a color temperature of up to 4000K-12000K. It uses a special ballast that uses the 2V voltage of the car electric pond to generate a trigger voltage of 23000V or more to start the lamp. The brightness of 0.8 seconds at startup is 20% of the rated brightness, reaching the brightness of the halogen lamp, and making the headlight reach 80% or more of the rated brightness within 4 seconds. After the lamp is stabilized, the ballast supplies approximately 80V of supply voltage to the lamp to maintain the lamp at constant power.
Performance advantages of xenon lamps (HID)
1, high brightness: the general 55W halogen lamp can only produce 1000 lumens of light, and the 35W xenon lamp can produce 3200 lumens of glare, brightness increased by 300%, with a long and super wide-angle wide field of vision, bringing you unprecedented Driving comfort; let the night no longer dark, clearer vision, can greatly reduce the traffic accident rate.
2, long life: HID xenon lamp is the use of electronically excited gas to emit light, so the long life, about 3,000 hours, greatly exceeds the total number of hours of night driving. The halogen lamp is only 500 hours.
3. Power-saving: The xenon lamp is only 35W, and the 55W halogen lamp emits more than 3.5 times of light, which greatly reduces the load on the car's power system, and saves 40% of the power loss, which improves the vehicle performance.
4, color temperature is good: there are 4300K-12000K, etc., 6000K close to daylight, praised by the majority of users, and the halogen lamp is only 3000K, the light color is dim and red.
5, constant output, safe and reliable: When the car's power supply system and battery failure, the ballast automatically shut down and stop working.
6, cold light source: HID is a cold light source, no heat, will not cause overheating damage to automotive parts.
5. How to add a lens (after adding 95% as a double lens)The lens is divided into single-lens lens and double-lens lens. The brand has Hella 1 generation (mainly used for Audi C5, A6, etc.) and Hella II (mainly used for BMW 5 Series, 7 Series, X5, Z4, Mercedes E Class and so on), Bosch (mainly used for golf GTI, Audi A4, Mercedes S-class, Volvo S40, etc.), Fario 2.75 inch (mainly used for Audi Q7), Fario 3 inch (mainly used for Cayenne, Touareg, Magotan and other models), domestically produced a lot of lens brands. After adding the lens, the corresponding lamp needs to meet the following requirements:
1. The premise of adding a lens is that the lamp must be a crystal face, which is transparent, without a pattern. Secondly, the space inside the lamp can be lowered by a lens.
2, single lamp (that is, far and near light split lamp) can be installed with a single lens, after installation, need D2S bulb or HID package. The high beam can be replaced by a lens, but it is usually equipped with a low beam.
3. Single-light double-lens lens: For example, the original car is a single-light H7. After adding a double-lens lens, the dual-lens lens itself has a near-far light function (a double-lens lens is a high-beam low beam that is transformed by the same lens. The high beam is close to the light, and the light is controlled by the high-beam power supply through the lens. The light-shielded light is raised from the low beam to the high-light light. The original high-beam light is still equal to the double light; after installation, it needs D2S-equipped bulb or D2S HID lamp.
4, double light plus double lens: after the double light plus double lens, the original car can not use the H4 bulb, you need to match the D2S bulb or HID bulb (use D2S clip and line plus H7 HID modified focus will Unstable).
5, 90% of the car is equipped with a puncturing lens, in addition to the need for a matching lens, it also needs to be equipped with the following accessories: D2S clip, D2S dedicated light.
It is equal to adding an angel eye LED aperture on the basis of adding a lens. The principle is the same as adding a lens, but it adds a simple process.
Seven, how to change the headlight assembly, install the angel eye headlight assembly, install HID xenon lamp
1, generally only say angel eye lamp assembly with angel eye LED aperture with lens; headlight assembly is dedicated to the car;
2, the general angel eye headlight assembly must have LED aperture with lens, but some with a single lens (most of the low beam), and some with a dual lens;
3, single-lens lens angel eye headlight assembly, generally equipped with the corresponding model of the headlights or HID according to its own model;
4, double-lens lens angel eye headlight assembly, need to match D2S bulb or HID bulb (with D2S clip and line plus H7 HID modified focus will be unstable).
The modification steps mainly include three steps of disassembly, installation and commissioning:
The first step is the disassembly process. The headlight assembly is first removed from the body. For some types of models, the front bumper must be loosened before the headlights can be removed.
The second step is to install the Goodway headlight assembly and connect all the cables.
The third step is to correct the light shape: since the left-handed rudder is driven by the right side of the road in China, the standard headlight illuminating light should be kept low left and right, the cutting line of the light should be very clear, and the lighting position cannot be exceeded. The height should not be too low, so as not to interfere with the safe driving of the other vehicle as the standard.
Eight, the installation of HID fault code real problemHID part of the car because the original car light is 55W, HID is 35W, so there will be a fault prompt, so the decoding line is needed to eliminate the original car fault signal.
Nine, the model of the lampD2SD means xenon lamp instead of other halogen lamps;
The numbers "1, 2, 3, 4", the singular number means the starter, and the double number means no starter, of which 1, 2 is mercury design, 3 and 4 are mercury-free design;
Letter: "S, R", S for the lens and R for the reflection.
Ten, LED light eyebrowsIt is a straight row of LED lights installed above the eye LED circle.
XI, single light lens / double light lens, single light / double light HID relationshipA single light lens refers to a near and far light split lamp, and a general single light lens is attached to the low beam light;
The HID of the single light refers to the non-H4 type lamp, that is, the far and near light split lamp, such as H7, H1, 9005, 9006, etc.;
The double light HID refers to the HID of H4, and the far and near light is dimmed by stretching on one lamp;
The double-lens lens realizes the near-to-near light conversion by blocking the light, so he cannot use the H4 model HID with its own dual-light function.
Twelve, lens + angel eye aperture modification calledMazda M6 Angel Eye Lens Refit - Hella Single Lens + Double Light Angel Eye Aperture;
Nissan Converse Angel Eye Lens Refit - Hella Double Lens + Angel Eye Aperture;
13. After the lens is modified, does the lamp type change?According to the above, if a lens is added, it must be equipped with a D2S halogen bulb or HID bulb, whether it is a single lens or a double lens.
Fourteen, the car is equipped with a lens, the tools needed for the angel's eye1. Oven, hair dryer, hot air gun, high temperature resistant glue, slotted screwdriver, cutting tool, file, electric iron, electric drill;
2, LED with resistors and wires (high brightness of 5000mcd or more), resistors, wires;
LEDs generally have red, yellow, blue, green, purple, white, and colorful colors. Generally, green brightness is the best, followed by white, followed by blue, yellow, red, and colorful.
Fifteen, how to remove the lampshadeMethod 1: directly put the lamp into the oven, set the temperature to about 120 degrees, then make sure the oven is not preheated, put it in, heat for 5-10 minutes, the heating time varies with the power of the oven, generally heating 4 After 5 minutes, I will continue to check it. If I look at it with my hand, I will continue to heat it. If it is more than 10-15 minutes (see the oven power, but it will not exceed 20 minutes), it can be easily opened by hand. The strength is like opening a solid pencil case. If it is too long, it is estimated that the plastic paste.
Method 2: With a heat gun, this comparison is not terrible, but the speed is fast. Just point the muzzle at the place where the glue is glued and slowly walk all the way to make sure that the glue is melted and the lamp cover can be opened.
Method 3: Use a hair dryer. For those who don't have the above two tools, put a flat-blade screwdriver on the air outlet of the glue, then blow it with a hair dryer. After enough temperature, the glue will melt, then use a screwdriver to get in, then continue to blow with the hair dryer. It’s good to blow while walking, but it’s slower.
The principle of opening the lampshade is to melt the glue, and then you can, so as long as you can melt the glue.
Sixteen, fixed angel eyesThe angel eye can be fixed on the lamp frame with high temperature resistant transparent glue. It must be resistant to high temperature glue. Because some of the lights used by Amoy friends have higher power, after a few hours of continuous lighting, the temperature inside the lamp will be very high. Ordinary glue, the glue will melt away, causing the angel's eye to fall off, causing a lot of unnecessary trouble.
Once it is fixed, connect the line of the angel's eye directly to the width light. After installing it, light up and try the effect.
Seventeen, sealed lampshadeMethod 1. Use a heat gun to slowly walk toward the glue on both sides of the lampshade. This will re-melt. At this time, the lid will be closed. Then you can apply a layer of sealant for double protection. I usually use it. Transparent and temperature-resistant silicone, waterproof and sun-resistant, there are many kinds of glue. If you are not sure, find someone in the garage to ask.
Method 2, put the lamp into the oven (for those who do not have a heating gun), but the sealing effect is the same, set the time first 2-3 minutes, then open the lid to check the glue, become a semi-liquid You can take it out and seal it, then add a layer of sealant.
The third method is to remove the original glue on the lampshade. It is best to remove the lampshade when it is first removed. Because the glue is soft, it is best to remove it. Use a one-word screwdriver to glue the glue. It is better to walk the groove twice, and then seal the sealant on the original groove and then re-package it.
Eighteen, the actual useThe next step is also to detect the working state of the angel's eye. If there is no problem, then the car is connected. If there is a problem, re-examine the step of removing the lamp cover. The one step of the connection should be no problem according to the calculation method given above. It is.
LED taillight modification:
The traditional car taillight structure generally includes a bulb, a reflective tile, and a dyed scattering mask. Such taillights have been used for nearly a hundred years. Due to the design requirements, aerodynamic requirements and aesthetic requirements, the shape of the low side streamlined shape is becoming more and more popular. The shape of the taillights is also moving towards alienation and integration. Although the new car has worked hard on the design of the taillights, it has been using the traditional design structure. In recent years, with the resolution of the LED brightness problem of the vehicle and the cost reduction, the application amount has increased rapidly. For example, LED chassis lights can be installed on the chassis of a car. At night, the car can emit very eye-catching lighting effects; LED lights are installed inside the car, and LED lights are turned on at night, and the interior of the car is red, blue, green or discolored, very Beautiful, the product is very popular among young riders. And LED taillights, not to mention, open it at night, will certainly attract a lot of envious eyes!
In fact, the advantages of LED taillights are far from this. In principle, because LEDs use electric field illumination, its response speed is faster. Ordinary halogen bulbs have a delay from the power-on to the filament illumination, which is the temperature rise time of the filament. For a 12 volt 21 watt bulb, this time is approximately 0.3-0.5 seconds. Suppose a car is driving at 80 km/h, which is equivalent to a braking distance of about 7-10 meters. The lighting delay of the LED is only a few tens of nanoseconds, which can be ignored. Therefore, the LED is used as a brake light, which can promptly remind the driver of the rear vehicle to take braking and avoiding, effectively avoiding the accident of being rear-ended. Secondly, the color temperature range of the LED is wide (1000-9000K), and the luminous intensity is high. As long as it is properly selected, it has good recognition under various meteorological conditions. Third, the LED has a long service life. In actual road traffic, we often see cars with incomplete lighting, which not only affects the appearance but also brings certain safety concealment. The actual life of domestic LEDs is around 30,000-80,000 hours. In the whole life cycle of LEDs, LED taillights generally do not need to be replaced and repaired. Fourth, the LED is a cold light source, and does not generate heat when it is operated, so the luminous efficiency is high. Fifth, LEDs have no combined structure and relatively moving parts, and have better shock resistance. In addition, the current during operation of the LED is small, and the load on the battery is negligible and does not cause the battery to lose power.
Due to the numerous advantages of LEDs, LED taillights are gradually being applied by major automobile manufacturers. It was first adopted in luxury cars such as BMW 7 Series, New Audi A8, Mercedes-Benz S-Series, and Lexus LS430. In recent years, LED taillights have been used in domestic vehicles such as Honda Accord, Toyota Crown, Camry, Reiz, Volkswagen Magotan, Sagitar, etc. It can also be seen on the mid-end models. Not only that, but due to the maturity of the conversion technology, it is not difficult to upgrade the taillights of the car to LED.
The steps of retrofitting LED taillights are much more complicated than other vehicle lighting modifications. First of all, not all models can be changed. This has a lot to do with whether the original taillights have scattering patterns. Modified LED taillights are best for crystal taillights without scattering patterns, such as Excelle, Mazda 6, Golf, Lingshuai, Jetta, New Bora, POLO, Tida, Corolla, New A6L, etc. If the tail light has a scattering pattern, it is not suitable. Modified LED taillights, such as the old A6, Buick LaCrosse and so on. The key to the model is that the size of the lamp is suitable for what type of LED conversion circuit board and the appearance is beautiful. Some models are not applicable to the standard modified circuit board, you need to redesign the circuit and test the actual use effect, so the modification cycle is relatively Will be longer. Most models have standard taillight LED boards that simply solder the LED bulbs to the board. The quality of the technician's welding is very important, which directly affects the reaction speed, service life and luminous efficiency of the LED. The next important task is to cut the taillights. If the cutting size is unreasonable, it will seriously affect the lighting effect and even cause the taillights to be damaged. After cutting the luminaire to determine the installation position of the circuit board, the LED circuit board can be fixed. The circuit board must be fixed firmly, because the bumpy vibration during the running of the vehicle may loosen the LED circuit board, and the safety must be eliminated. Hidden dangers. The next job is to perform a sealing process. The edges of the cut parts should be glued firmly to prevent the lamps from entering the water during future use. The modification work is basically completed here, but for some vehicles that are sensitive to driving computers, such as Mazda 6, Toyota Prado, because the tail light will cause the computer to generate a fault code, it is necessary to install a special resistance resistor in the LED circuit. Effectively solve the problem of trouble codes. If the fault code is ignored, the vehicle computer may automatically turn off some functions of the original car such as anti-skid, ABS, etc. After the sealing work is completed, the modified taillight assembly is replaced and the dedicated non-destroyed original vehicle line connector is used to connect the circuit. The modification of the LED taillights is done.
