Whether it is standard or modified, as the most beautiful type of car lights, LED lights are slowly becoming popular. From the Guangbenling to the new Lion Run, to the Dongfeng Fengshen New S30 and other self-owned brand models, the LED lights previously found in mid- to high-end models have already begun to spread to low-end models.
Compared with traditional halogen lamps, LED lamps are more energy-efficient, environmentally friendly, and smaller in size. They are also flexible and easy to arrange, and can easily create a front face model. However, although LED lights are more cool and cool, their maintenance costs are also more expensive than conventional lights.
LED lights into the mainstream of car headlights:The development of LED daytime driving lights is actually some years old, but at the beginning, the prices of the models carried are all relatively high, and they are not so popular. Car fan enthusiast Xu Fan said that BMW and Passat's daytime running lights are all excellent designs. Audi is also known as the “Lamp Factoryâ€, “Eagle Eyeâ€, “Sickle†and “Lightning†It is a familiar LED light design.
Daytime driving lights in addition to cool, but also ensure traffic safety. Vehicles equipped with daytime running lights are better able to be recognized by the opposite vehicle in the event of daytime glare or poor visibility in rain and fog. As a safety device, many European countries have forced manufacturers to match daytime driving lights.
Mr. Guo, owner of Hangzhou Automobile City Auto Parts Market, said that LED lights are not only dazzling, but also the brightness of full LED headlights even exceeds the xenon headlights, which lightens the response speed, but the price is relatively high, and the price ranges from 30,000 to 80,000 yuan. The original car configuration only Audi, Mercedes-Benz and other luxury brands, some models, the late conversion of fans is relatively small.
Although the LED lights dazzling, but its high maintenance costs allow owners to call out "can not afford to hurt."
Recently, Hangzhou Cheyou Xiao Lv was annoyed at the maintenance cost of his car BMW 3 Series of thousands of dollars. Xiao Lu suddenly discovered a few days ago the car's turn signal is broken. Checked to the 4S shop for repair and found that the original bulb was burned out. At the beginning, Xiao Lv also did not take it for granted that he felt that changing a light bulb would also cost tens of dollars. "Think about 200 yuan at the time and you can definitely get it. But whoever wants to, 4S shop tells him that the maintenance cost was nearly 2,000 yuan." Xiao Lu was upset. He said that the maintenance worker told him that this LED turn signal could not replace the light bulb alone. If it was broken, the entire assembly must be replaced. There is no other way.
The new Crown owner Mr. Meng also had the same experience. "At that time, the LED brake lights did not shine. To ask the 4S shop for the entire assembly, the cost exceeded 1,500 yuan." Mr. Meng said puzzled, unexpected outside repair shop offer the same more than a thousand dollars. Recalling that the original old car replaced a halogen bulb as long as tens of dollars, Mr. Meng directly called "can not afford to hurt."
"The change of turn signal or brake light is still good. If it is a full LED headlight, the cost will be 10,000 yuan." Said Xiao Ding, a circuit maintenance master at 4S shop in Japan, said that the replacement cost of an LED lighting assembly like the Audi A6L is close to 1.2 million.
Pay attention to the heat dissipation of the surrounding environment of LED lights:“The concept of design and manufacture 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 parts in the market is also moving toward overall development.
Compared with traditional halogen bulbs, LED lamps theoretically have a longer lifetime and are more aesthetically pleasing, but due to the normal operating temperature of LED lamps is below 60°C, while the headlights of vehicles are in use, or under high temperature exposure, LED lamps The surrounding temperature will become very high, and the heat dissipation is not very fast. Once the temperature exceeds 60°C, the work of the LED lamp will not be particularly stable, and it will even burn off. "For the majority of LED lamp damage, all lights will not be turned off at once. Taking into account the high cost of replacement of LED lights, owners can replace the lamp when the number of failure lamps affects the use effect, thereby reducing maintenance costs. â€
The biggest factor influencing the lighting efficiency and lifespan of LED cars is temperature, so owners who want to modify LED lights are advised to choose LED lamps with good thermal conductivity, and pay attention to the heat dissipation of the surrounding LED lights in the installation process.
(1) After confirming the model number, it is best to ensure that the vehicle turns off before starting to replace the headlights. Unplug the vehicle key until the engine is completely cooled.
(2) Open the hood of the engine, simple replacement of large bulbs generally does not require the removal of the headlight assembly, different ways of fixing the car lights are slightly different, in general there will be a dust cover at the tail of the headlights, hard twist After opening, you can see the wire clips of the headlights. You can remove the headlights with a firm grip.
(3) After taking out the bulb, you can unplug the bulb from the power connector. The action should be light to avoid damaging the power connector.
(4) Take out the new light bulb from the product packaging box, remembering not to touch the glass part of the bulb with your fingertips, so as to avoid affecting the life of your hand by mistakenly sticking to the glass. It is best to wear gloves when operating. Install the lamp on the power connector.
(5) Fix the bulb on the wire retainer and screw the seal on.
In the car headlights, the light shape of the lens head is the most standard, there can be obvious light and dark cutting lines, to solve the problem of astigmatism, in foreign countries, xenon lamps are used as standard lenses, this mirror belongs to the optical mirror In class, we call it "lens". Headlamps with lens-type lamp heads have the advantages of uniform brightness, strong penetrating power, and small loss of light compared to headlights using conventional lamp heads.
There are two kinds of lens heads for vehicle equipment: single light and double light. Inside the single-lens lens, there are also designed corresponding to the near and far light lens, such as: M6's low-beam lens, Mondeo far-light lens; the difference between the two-lens lens is that it can make similar far and near light conversion, Normally, it is in the state of low beam. When the high beam is turned on at the same time, it changes the light beam by the electromagnetic mechanism, so that the light in the low beam is also distributed to the high beam light, equal to two high beams. Double light lens is generally used in high-end cars, such as A6. BMW. Mercedes-Benz and so on.
Second, what is called angel eyesAngel eyes - a kind of car lights.
The angel eye headlights refer to the yellow or other colors of the halo formed by the LED lights that surround the light heads of the near and high beams. They are beautiful under wide-light conditions. Mainly from the decorative appearance and widening effect, the color red, blue, green, yellow, purple range.
Originally from the BMW 5 Series headlight design, when the headlights were turned on, BMW's headlights would have a halo. This aura resembled the halo of an angel's head, so many users gave her a nickname: Angel Eye. Under normal circumstances, the original "Angel Eye" headlights will match the lens head and Xenon headlights. Angel eyes are divided into two kinds, (1) cathode tube, material: glass, need starter, brightness is very high, beautiful appearance, long life, uniform light emitting parts, from that point of view can clearly see the clear. (2) LED, material, light-guiding plastic, similar to BMW Angels Eye; general modifications are used LED structure, so called the angel eye LED aperture; but sometimes people simply put the headlight assembly with angel eyes simply called the angel Eyes, or angel eye headlights, angel eye headlight assembly, is actually confusing the concept, the correct angel eye concept should refer to the angel eye aperture.
Third, what is the angel eye headlight assemblyThe angel eye headlight assembly is actually a headlamp assembly with an angel eye LED aperture, some with lens and some without a lens, some with a single light lens (mostly low-beam lenses), and some with a double light lens The installation of it will not only make your car look bright and beautiful in the car. It will allow you to install the xenon headlights not only to increase the illumination, but also to improve the night vision. The key is not to cause danger to others.
Fourth, what is called HID xenon lampXenon lamp is a new type of headlight containing xenon gas, also known as high-intensity discharge gas lamp, referred to as HIDIntensityDischargeLamp in English. The xenon lamp broke the principle of tungsten filament invented by Edison. The quartz lamp was filled with high-pressure inert gas, Xenon xenon, to replace the traditional filament. There were mercury and carbon compounds on the two electrodes, and the voltage was 23000 volts through the ballast. The current stimulates the glow of the xenon, creating a perfect white arc between the two poles. The light emitted is close to perfect sunlight.
Unlike traditional halogen lamps, automotive HID xenon lamps are high-pressure discharge lamps whose light-emitting principle uses positive and negative electrical stimulation to stimulate the reaction of xenon with rare metals. Therefore, there is a small glass ball in the lamp tube. It is filled with helium and a few rare metals. As long as the current is used to stimulate them to react chemically, both will emit light with a temperature of 4000K-12000K. It uses a special ballast to make the lamp start using the car's electric voltage of 2V to generate a trigger voltage of more than 23000V. The 0.8 second brightness at start-up is 20% of the rated brightness, reaches the brightness of the halogen lamp, and makes the headlights reach 80% or more of the rated brightness within 4 seconds. After the lamp stabilizes, the ballast provides about 80V supply voltage to the lamp to keep the lamp running at constant power.
HID Performance Benefits
1, high brightness: general 55W halogen lamp can only produce 1000 lumens of light, and 35W xenon lamp can produce 3200 lumens of light, brightness increased by 300%, has a wide and super wide-angle wide field of vision, to bring you unprecedented The comfort of driving; let the night is no longer dark, clearer vision, can greatly reduce the rate of traffic accidents.
2, long life: HID xenon lamp is the use of electronic excitation gas light, so the long life, about 3000 hours, significantly exceeded the total number of hours of night driving. The halogen lamp is only 500 hours.
3, energy-saving: xenon lamp is only 35W, and issued more than 3.5 times the 55W halogen lamp light, greatly reduce the load of the automotive power system, power loss to save 40%, and accordingly improve vehicle performance.
4, color temperature is good: there are 4300K-12000K, etc., 6000K close to the sun, praised by the majority of users, while the halogen lamp is only 3000K, dark red light color.
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 damage to the auto parts overheating.
Fifth, how to install the lens (post-installed 95% dual-lens lens)Lenses are divided into single-lens and dual-lens lenses, the brand has a generation of Hella (mainly used in Audi C5, A6 and other models), Hella II (mainly used in BMW 5 Series, 7 Series, X5, Z4, Mercedes-Benz E Grades, etc.), Bosch (mainly used for Golf GTI, Audi A4, Mercedes-Benz S-class, Volvo S40, etc.), Fario 2.75-inch (mainly for Audi Q7), and Fario 3-inch (mainly used for Cayenne, etc.) Touareg, Magotan and other models), China has also come out a lot of lens brands. After adding the lens, the corresponding lights need to meet the following requirements:
1, the precondition of installing the lens is that the lamp must be a crystal surface, that is, transparent, no pattern, and secondly, the space within the headlight can be put down a lens.
2. A single light (ie, a far-and-far light split lamp) can be equipped with a single light lens. After installation, a D2S bulb or HID kit is required. You can change lenses for high beam and low beam, but they are generally equipped with low beam.
3, single-optical installation of bi-optical lenses: For example, the original car is a single light H7, after the installation of bi-optical lenses, the bifocal lens itself has far and near light function (bi-optical lens is high beam near light with the same lens for transformation, Far-beam near light is used by the lens solenoid valve through the high-beam power supply control lift up the light-blocking film by the light to change the far light), the original car high beam light is still there so it is equal to double far light; after installation, need Equipped with a D2S bulb or D2S HID lamp.
4, dual-lens plus bi-optical lens: dual-lamp plus bi-optical lens, the original car can not use the H4 bulb, need to adapt to D2S light bulbs or HID bulbs (with D2S clips and lines plus H7 HID conversion will focus Unstable.
5, 90% of vehicles installed pun lens, in addition to the need for matching lenses, but also need to be equipped with the following accessories: D2S clip, D2S special variable light.
Equal to the plus lens basis, plus an angel eye LED aperture, the principle is consistent with the plus lens, just add a simple process.
Seven, how to change the headlight assembly, install the angel eye headlight assembly, install HID xenon lamp
1, generally only said with Angel Eye LED aperture lens angel headlight assembly; headlight assembly is dedicated to the car;
2, the general angel eye headlight assembly must bring a lens with LED aperture, but some with a single optical lens (most of the low beam), some with a double optical lens;
3, single-lens lens angel headlight assembly, generally according to its own model with the corresponding model of the lamp or HID;
4. The double-lens Angel-Eye-Headlight Assembly requires a D2S bulb or HID bulb to be reconfigured (with D2S clips and lines plus the H7 HID's modified focus will be unstable).
The modification steps mainly include three steps: dismantling, installation and debugging.
The first step is the dismantling process. The headlight assembly is first removed from the body. For certain types of vehicles, the front bumper must be released before the headlights can be removed.
The second step is to install the Goodway headlight assembly and connect all the connecting wires.
The third step is to correct the light shape: Since China implements the rule that the left rudder car is on the right side of the road, the standard headlight illumination lamp shape should keep the left low right high, the cutting line of the light should be very clear, and the lighting position of the light can not be over The height should not be too low so as not to interfere with the safety of the other vehicle.
Eight, install HID fault code real problemHID part of the car because the original car lights is 55W, HID is 35W, so there will be fault prompts, so the need to decode the line to help eliminate the original car fault signal.
Nine, the lamp modelD2SD represents xenon lamps rather than other halogen lamps;
Numbers "1, 2, 3, 4", single number with starter, double number with no starter, of which 1,2 for mercury design, 3,4 for mercury-free design;
Letters: "S, R", S for lens, and R for reflection.
Ten, LED light eyebrowIt is a straight LED LED lamp installed above the top of the eye LED ring.
Eleven, single light lens / dual light lens, single light / dual light HID relationshipA single-lens lens refers to a far-and-far light split lamp, and a general single-lens lens is mounted on a low beam lamp;
Single-light HID refers to non-H4 type lamps, ie, far and near light split lamps, such as H7, H1, 9005, 9006, etc.
HID refers to the HID of the H4. The far and near light is dimmed by stretching on one lamp.
The bi-optical lens realizes the conversion of far and near light by blocking light, so he cannot use the H4 model with its own dual-light function.
Twelve, Lens + Angel Eye Aperture RenamedMazda M6 angel eye lens conversion - Hella single light lens + double angel eye aperture;
Nissan Converse Angels Eye Lens Conversion - Hella Double Optical Lens + Angel Eye Aperture;
Thirteen, after the lens is modified, the lamp bulb model changesAccording 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 light lens or a double light lens.
XIV. Tools needed to install lenses and angel eyes1. Ovens, hair dryers, hot air guns, high temperature adhesives, slotted screwdrivers, cutting tools, files, soldering irons, electric drills;
2, LED with resistance and wire (high brightness above 5000mcd), resistance, wire;
LED generally has red, yellow, blue, green, purple, white, colorful, generally the best green brightness effect, followed by white, followed by blue, yellow, red, colorful.
15. How to remove the lampshadeMethod one: directly into the oven inside the lamp, set the temperature of about 120 degrees, and then determine that the oven is not preheated, put it in, heating 5-10 minutes, the heating time varies due to the size of the oven power is different, the general heating 4 After 5 minutes, keep watching, look at it with your hands, and if it is firmer, continue heating, for a maximum of 10-15 minutes (see the oven power, but it will not exceed 20 minutes), you can easily pull it out by hand, The intensity is probably like opening a firm pencil box. If it is too long, it is plastic paste.
Method 2: With a heat gun, this comparison is not terrible, but the speed is faster, that is, the gun mouth at the place where the sealant slowly go all the way to determine the glue melts, can open the lampshade like.
Method 3: Use a hair dryer. For those who do not have the above two tools, the slotted screwdriver is stuck in the glue outlet, and then blows with a hair dryer. When the temperature is enough, the glue melts. Then it is stuck in with a screwdriver and continues to blow down with a hair dryer. It's good to blow while you walk, but it's slower.
The principle of opening the lampshade is to melt the glue, and then it will be enough, so as long as everyone can melt the glue just fine.
Sixteen, fixed angel eyesYou can use high-temperature transparent glue to fix the angel eyes on the light frame, must be high-temperature glue, because some of Amoy Friends of the car light power is high, after a few hours of continuous lighting, the lamp temperature will be high, if it is Ordinary glue, glue will melt out, so that the angel's eyes fall off, causing a lot of unnecessary trouble.
Once fixed, connect the angel's eye directly to the width indicator. After installing, light up and try the effect.
Seventeen, sealed lampshadeMethod one, with the heat gun on both sides of the lamp cover slowly go side, this will re-melt, this time just put the lid closed, and then you can double layer of sealant for double protection, I generally use Transparent temperature silicone, waterproof and solar resilience, there are a lot of glue, if you are not sure, then find a garage to ask about it.
Method two, put the light into the oven (applicable to riders without a heat gun), but the sealing effect is the same, the time set first 2-3 minutes, and then open the lid to check the glue condition, into a semi-liquid When it's time, you can come up with a seal, and then add a layer of sealant just fine.
The third method is to remove the original glue on the lampshade. It is best to remove the lampshade when you first remove the lampshade because it is best to remove the glue when it is soft. Use a screwdriver with a flathead and follow the glue. It's good to walk the groove 2 times, and then seal it by putting the sealant in the original groove and then re-encapsulating it.
18. Actual useThe next step is also to check the working status of the angel's eye. If there is no problem, then load the car. If there is a problem, check the steps above to remove the lampshade. The connection step should be no problem according to the calculation method given above. Now.
LED rear light modification:
The traditional taillight structure of a car generally includes a light bulb, a reflective tile, and a stain scattering mask. Such car taillights have been used for nearly a hundred years. Automotive Profile Due to design needs, aerodynamic requirements, and aesthetic needs, low-profile, streamlined shapes are becoming more popular. The shape of taillights has also evolved toward heterogeneity and integration. Although the new car has been designed with a high degree of taillight design, traditional design structures have been used. In recent years, with the resolution of automotive LED brightness problems and the decline in costs, their applications have grown rapidly. For example, an LED chassis light is installed on the chassis of a car. At night, the car can emit a very eye-catching lighting effect; LED lights are installed inside the car, LED lights are turned on at night, and the interior of the car shows a red, blue, green, or discoloration. Beautiful, the product is very popular with young riders. The 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 the same. From the principle, since LEDs use electric fields to emit light, their response speed is faster. An ordinary halogen bulb has a delay from the power on to the glow of the filament, which is the temperature rise time of the filament. For a 12 volt 21 watt light bulb, this time is about 0.3-0.5 seconds. Suppose a car is driving at a speed of 80 kilometers per hour, which is equivalent to a braking distance of about 7-10 meters. The light emitting diode has a delay of only several tens of nanoseconds, which is negligible. Therefore, the light emitting diode is used as a brake light, which can promptly remind the rear vehicle driver to adopt braking and avoidance so as to effectively avoid the accident of being rear-ended. Secondly, the LED's color temperature range is wide (1000-9000K), and its luminous intensity is high. As long as it is properly selected, it has good visibility under various weather conditions. Third, the LED has a long service life. In real road traffic, we often see cars with incomplete lighting, which not only affect the appearance but also bring about a certain degree of security. The actual service life of the domestic light-emitting diodes is in the range of 3 to 80,000 hours, and LED taillights generally do not need to be replaced or repaired during the entire life cycle of the automobile. Fourth, LED is a cold light source and does not generate heat during operation, so it has high luminous efficiency. Fifth, LED has no combined structure and relative moving parts, and its shock resistance is better. In addition, the current when the LED is working is very small, and the load on the battery is negligible, which will not cause the battery to lose power.
As LED has many advantages, LED taillights are gradually being applied by major automobile manufacturers. It was adopted on luxury cars such as the BMW 7 Series, the new Audi A8, the Mercedes-Benz S-Series, and the Lexus LS430. In recent years, LED taillights have been used in domestic cars such as the Honda Accord, Toyota Crown, Camry, Reiz, Volkswagen Magotan and Sagitar. It can also be seen on mid-range models. Not only that, due to the maturity of the conversion technology, upgrading the rear light of the car to LED is not difficult at present.
The steps of modifying the LED taillights are more complex than those of other vehicle lighting modifications. First of all, not any vehicle model can be changed. This is very much related to whether the original taillights have scattering patterns. Modified LED taillights are best equipped with non-scattered crystal taillights such as Excelle, Mazda 6, Golf, Optimus, Jetta, New Bora, POLO, Tiida, Corolla, new A6L, etc. If the taillights are not suitable for scattering patterns Modified LED taillights, such as the old A6, Buick Lacrosse and so on. After determining the model, the key is whether the size of the lamp is suitable for what type of LED modified circuit board and the appearance is beautiful, some models do not apply the standard modified circuit board, need to redesign the circuit and test the actual use effect, so that the conversion cycle is relatively It will be longer. Most models have a standard taillight LED circuit board. Simply solder the LED bulb to the circuit board. Technical staff welding quality is very important, which directly affects the LED's reaction speed, service life, and luminous efficiency. The next key task is to cut the taillight lamps. If the cutting size is unreasonable, it will seriously affect the irradiation effect and even cause the taillights to be damaged. After cutting the fixtures 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 jolt vibration in the driving process of the vehicle may loosen the LED circuit board, and the resulting safety must be eliminated. Hidden danger. The next job is to seal it. The edge of the cutting part must be glued firmly to prevent the lamp from entering the water in the future. The modified work is basically completed, but for some models that are sensitive to driving computers, such as Mazda 6, Toyota Prado, due to changes in taillights will cause the computer to generate fault codes, you need to install additional resistors in the LED circuit in order to be able to Effectively solve the problem of fault codes. If you ignore the fault code, the vehicle's computer may automatically close some of the original car features such as skid prevention, ABS and so on. After the sealing work is completed, replace the modified taillight assembly and select the dedicated undamaged original vehicle line connector to connect the circuit. The modification of the LED taillights will be completed.
