What is the function of the lampshade installed on the car s lights?

Install car headlights.

The function of the lampshade is: the installation of the lampshade can turn the light source in different directions of the bulb into a controllable parallel light source through the corresponding angle and refraction, and reflect it to ensure the safety of yourself and the other party's driving; The lampshade of the headlight is specially designed to refract a small portion of the light slightly upwards and sides to illuminate road signs and road signs. Horizontal and vertical striped glass lampshades are often used for car headlights because it is a combination of a lens and a prism that can refract and disperse light in the desired direction.

When this lampshade is installed, the headlights can evenly and gently illuminate a large area in the direction in which the car is heading.

The functions of the lampshade installed on the lamp of the automobile are as follows: Protect the bulb: The lampshade can avoid the bulb from being directly impacted and polluted by the outside world, thereby prolonging the service life of the bulb.

Prevent glare: Lamp shades can reduce glare from other vehicles and pedestrians, and improve driving safety. Beautify the appearance:

The design of the lampshade can enhance the appearance and aesthetics of the car, and increase the sense of style and personality of the vehicle. In short, the lamp shade is an important part of the automobile lamp, which has multiple functions of protection, safety and aesthetics.

The function of the car's lamp cover is to improve the lighting effect of the lamp, reduce glare, improve the visibility of the lamp, and can improve the appearance of the lamp.

It is a plastic called polycarbonate (also known as PC resin spectacle lenses).

In the 60s of the last century, the United States developed a plastic called polycarbonate (also known as PC resin spectacle lenses), authentic vehicle headlights and taillight glass covers, labeled polycarbonate (also known as PC resin, spectacle lenses are this material) injection molding.

Some high-end car lampshade molds have particularly high precision injection pressure time requirements, and at the same time, the toner used for lampshade injection molding is good for light transmission with high-grade transparent toner. Polycarbonate has high hardness, high strength, great toughness, and good UV light transmittance, so the color becomes transparent after the authentic lampshade is used for time, and the whole mold of the counterfeit lampshade is the reverse drawing modeling of the original lampshade, because the original lampshade will be slightly deformed in the injection molding process and cooling process, so the reverse mapping of the drawing inherits this deformation, and the size of the finished product is determined from the drawing, which affects the dimensional accuracy of injection molded products. In order to reduce the cost of materials and processing costs, the injection material of counterfeit lampshade is made of acrylic, which has high transparency and is relatively hard, looks beautiful when it is new but lacks toughness, fragile and has no anti-ultraviolet ability, and is easy to age and yellow and fade in outdoor sunlight, so counterfeit tail lights are easy to fade and white, and fake front lights are easy to hair and white.

Now the shape of the lights are matched with the shape of the whole vehicle, the shape is complex, the complex shape of the glass can not be made, thanks to the United States in the 60s of the last century for the astronaut mask in the moon landing program, and developed a plastic called polycarbonate (also known as PC resin spectacle lens on this material), Authentic vehicle headlights and taillight glass covers, labeled polycarbonate (also known as PC resin, spectacle lenses are this material) injection molding, especially some high-end car lamp cover mold precision injection pressure time requirements are particularly high, at the same time, Toner for lampshade injection molding, with high-grade transparent toner for good light transmission. Polycarbonate has high hardness, high strength, great toughness, and good UV light transmittance, so the color becomes transparent after the authentic lampshade is used for time, and the whole mold of the counterfeit lampshade is the reverse drawing modeling of the original lampshade, because the original lampshade will be slightly deformed in the injection molding process and cooling process, so the reverse mapping of the drawing inherits this deformation, and the size of the finished product is determined from the drawing, which affects the dimensional accuracy of injection molded products. In order to reduce the cost of materials and processing costs, the injection material of counterfeit lampshade is made of acrylic, which has high transparency and is relatively hard, looks beautiful when it is new but lacks toughness, fragile and has no anti-ultraviolet ability, and is easy to age and yellow and fade in outdoor sunlight, so counterfeit tail lights are easy to fade and white, and fake front lights are easy to hair and white.

The headlights are produced using polycarbonate materials, the tail lamp covers are produced with acrylic materials, the rear shells of the headlights of various automobile manufacturers are made of PP plus 20 to 30 percent of the reinforced fiber, and the tail lamp back shells are made of alloy materials (ABS plus 30 percent of polycarbonate, after chemical synthesis) The lamp covers are produced of acrylic materials, and the ABS and PC without chemical treatment cannot be fused.

Car headlight hood function:

1. The headlight hood of the car is to prevent the light from diverging and make the light better gathered. The light of the car bulb is mainly reflected through the reflector installed on the inside, and if there is no hood, the light is poorly concentrated, and the reflection effect is reduced.

2. When shooting in the forward light and side light, the scattered light around it can be avoided from entering the lens.

3. The headlight hood of the car can prevent the car from dazzling the other driver when driving at night.

4. It can prevent accidental damage to the lens, and can also avoid fingers touching the surface of the lens by mistake, and can also shield the lens from wind, sand, rain and snow to a certain extent.

5. In light photography or night photography, you can avoid the surrounding interference light from entering the lens.

Car headlights, also known as car headlights, car LED daytime running lights, as the eyes of the car, are not only related to the external image of a car owner, but also closely related to safe driving at night or in bad weather conditions. The use and maintenance of car lights cannot be ignored.

Low beam hood:

A light shield is installed underneath the low beam filament to shield the light cast at the driver of the oncoming vehicle, and its edge shape allows the beam to shine on the road surface to form a cut-off line.

Only the following part is illuminated to the half side of the oncoming vehicle on the road, thereby the driver of the oncoming vehicle can be prevented from dazzling; In front of the car, it illuminates the road surface at a high enough distance (more than 100 meters) and a high enough space (more than two meters) to ensure good front lighting of the car.

The function of the hood is to prevent the light from diverging and making the light better concentrated. Remove the hood and the light line will not become brighter, the light of the bulb is mainly reflected through the reflector installed on the inside, if there is no lens hood, the light is poorly concentrated, and the reflection effect is reduced.

To put it bluntly, it's spotlight! Not scattered.

The glass covers of the headlights and taillights of authentic vehicles are injection molded from high-grade polycarbonate (also known as PC, which is the material used for resin spectacle lenses). Polycarbonate has high hardness, high strength, high toughness, UV resistance and good light transmittance. Therefore, the color of the authentic lampshade does not change after a long time of use, and the transparency is good.

As the eyes of the car, car headlights are not only related to the appearance of a car owner, but also closely related to driving at night or safe driving in bad weather conditions.

Maintenance of lights.

1. Prevent moisture from entering the headlights;

2. Have good car habits, and develop good car habits in the daily car use process;

3. Replace the bulb regularly, the car bulb is a consumable product, with a fixed service life, and should be replaced in time after the service life;

4. Routine inspection, regularly check whether the lights are working normally, and if you find a problem with which lamp, you must repair it in time;

5. Repair the broken lamp in time, if you accidentally hit a certain lamp and there is a crack, you must repair it in time to prevent failure during use.

BelongsIllegal Behavior, illegal modifications. If the normal annual inspection is not possible, the insurance company can refuse to pay when the accident is claimed.

Illegal modification of the vehicle is the appearance and power system of the vehicle.

Transmission system, braking system.

Carry out modifications that are not permitted by national laws and agreed by the manufacturer beyond the design load capacity and function of the original vehicle. This includes the act of replacing critical components.

Exterior modification: change the body exterior logo, color, sticker, open the sunroof.

The front and rear bumpers, luggage racks, rear spoiler and tire rims were added.

upgrades to the chassis, etc.;

Modification in the car: Modification of the in-vehicle facilities, including the steering wheel.

the replacement of sports seats and the addition of instrumentation equipment and sound-reducing materials;

Upgrade the power system: Modify the exhaust pipe, turbine, etc., and use the gap between the design power of the engine and the actual power to increase the instantaneous displacement.

Provisions

After changing the body color, body or frame, the owner can go to the vehicle management department to change the mold verification registration within 10 days after the replacement.

Modified wheels with tires, tires, and the installation of tail wings, lights, exhaust pipes, etc., are all illegal modifications, and they need to be restored to their original state in time in order to pass the inspection, and will also be given fines, deductions and other penalties.

The function of the automobile headlight lamp cover is to seal and protect the bulb. If the headlight lampshade is damaged and not replaced in time, water mist may appear inside the headlight, which will affect the car lighting, and even water will enter the circuit and damage the lamp.

The fog treatment measures in the headlights are as follows: there is no need to worry too much about the fog in the headlights, after the lights are turned on for a period of time, the fog will be discharged from the lamp with the hot air through the snorkel, and it will not hurt the headlights. However, the headlights should never be baked, as it is easy to burn the headlights.

The treatment measures for serious water ingress in the headlights are as follows: if there is too much water inside the headlights, you should go to the 4S shop for dismantling and maintenance as soon as possible. Then it is necessary to disassemble the headlamp and open the lampshade, check whether the surface of the headlamp is damaged or may leak after drying, if no abnormality is found, you need to replace the headlight back cover sealing strip and snorkel and other hardware equipment.

If the water accumulation is severe, the headlights need to be replaced.

Extended InformationThe reasons why car headlights have water mist are as follows:

1. The temperature difference in winter is large, resulting in the internal condensation of the headlamp There is a ventilation pipeline linking to the outside world in the structure of the automobile headlight, the purpose of which is to increase the temperature after the headlight is lit, and the gas expanded inside the headlamp is discharged through the ventilation pipeline, after the headlight is extinguished, the temperature decreases, the internal pressure difference becomes larger, and the outside air is inhaled through the ventilation tube, the humid air will be inhaled, causing the headlamp to condense into fog.

2. Heavy rain and fog are easy to produce after washing the car, and if you don't pay attention to it when washing the car, use the water gun to directly rush the engine compartment or car headlights, and then the water droplets will flow directly into it. When the vehicle wades in water, because the engine and exhaust system itself are relatively large heat sources, rainwater will form a large amount of water vapor on it, along the ventilation pipe, part of the water vapor.

Because the "stray light" of the lamp tip is removed late at low beam, the dividing line is more obvious

1. The tail light indicates the existence of a car in front of the rear car when driving at night, and shows the position relationship between the two workshops, so it is installed on both sides of the rear of the car;

2. The safety regulations in Japan are the same as those of the European standard ECE7. The luminous intensity near the center is 4 12cd, and the light color is red;

3. At present, the light source used in automobile tail lights is mainly incandescent lamps, and some new light sources such as light-emitting two machine tubes (LED) and neon lights have also appeared.

1. Mold for making lampshade: First of all, you need to prepare a mold that meets the design requirements, which can be achieved through 3D printing, hand carving, woodworking and other methods. The material of the mold can be polyurethane, gypsum, silicone, etc.

2. Materials for making lampshades: The materials commonly used are transparent acrylic sheets, PC sheets, PET plates, etc. These materials can be purchased in places such as craft stores, plastic processing plants, etc.

3. Cutting materials: Cut the lampshade material according to the size of the mold, and you can use cutting knives, chainsaws and other tools. 4. Make the shape of the lampshade:

The cut lampshade material is placed in a mold, heated with a heater or oven to soften it, and then pressed into the desired shape with a tool. Be careful not to overheat the material so that it does not deform or scorch. 5. Shaping and grinding

The finished lampshade is cooled in water or in a cooler to allow it to cure. Then use a sander, sanding cloth, etc., to trim and sand the edges of the lampshade to make it look smoother. 6. Installation:

Install the prepared lampshade into the lamp and adjust it to ensure that it matches the lamp's interface and mounting position.

Dear, it needs to be noted that the lamp cover is one of the important parts of vehicle driving safety, and the safety and compliance issues need to be taken into account when making the song file as the lamp cover. If you do not have the relevant production experience and skills, it is recommended to seek the help of a professional car mechanic or a 4S shop.

You can make it over there.

Kiss, you can't do it here.

I don't have a lamp cover here.

You can visit the 4S shop.
