Now, more and more technology configurations are flooding every detail of the car, and headlights are no exception. Previously, Xiao Bian had introduced the difference between halogen headlights and xenon headlights, so today Xiaobian will talk about the common technology configurations equipped with car headlights.
In terms of the types of headlights, the current common headlights are divided into halogen headlights, xenon headlights and LED headlights.
Halogen headlights: Halogen lamps began to be applied to the body in the 1970s. The principle of illumination is very similar to that of ordinary incandescent lamps, that is, the heat generated by the spiral tungsten filaments in the lamp is illuminated by the tungsten wire itself. Limit of melting point.
Xenon headlights: The English abbreviation for Xenon lamps is HID gas discharge lamps, which were first used in air transportation. It has no filament, but uses high-voltage positive and negative electricity to stimulate the helium in the bulb to react with rare metals to illuminate.
LED headlights: LED is the abbreviation of Light Emitting Diode, which has a very popular Chinese name - LED. LED headlights have the characteristics of high luminous efficiency, more energy saving, longer life and better durability.
At present, we often see traditional headlights and fog lights. There is also a row of LED light sources in front of the car, and its role is not what lighting, this is the LED daytime running lights. The LED daytime running light is a daytime driving light that is mounted on the front of the car. Jane's main function is not to enable the driver to see the road, but to improve the visibility of the vehicle in a situation where the daytime driving line environment is poor, so that pedestrians and cars and between cars and cars can be earlier and better. The detection and identification, prevention of accidents in advance, and ensuring driving safety.
And often with the headlights is the lens. The lens has a strong concentrating ability, uniform brightness, and strong penetrating power, which allows the light range to be farther and clearer than the range of the light without the lens.
Headlight cleaning: When the car is driving at night or in low light, rain and dust will reduce the illumination of the headlights by 90%, and the driver's line of sight is seriously affected. For driving safety, there is a big hidden danger. . The headlight washer provides a simple and effective way to solve this problem. Laws in many countries now require that headlamp cleaning systems be installed on cars. The current common headlight cleaning device is a high pressure cleaning system.
The height of the headlights is automatically adjusted: the automatic control of the height projection headlights is adjusted according to the weight of the vehicle and the speed of the vehicle to adjust the illumination distance, especially when going up and down.
Automatic headlights: In the environment where the light suddenly becomes dark when driving, the headlights will automatically turn on and automatically turn off when the light is sufficient. There is also a situation in which the near and far lights are automatically changed when the car is parked at night. The principle is to use an electronic component such as a photoresistor as a sensor (mounted on the back side of the interior rearview mirror, etc.), and send an electronic signal to the ECU (the electronic control unit, which means a CPU of the computer), and then the ECU according to the signal Control the switch of the headlights and the change of the far and near light.
Curved Auxiliary Lighting: The Static Cornering Light is an auxiliary source that illuminates the turning area. At intersections or corners, corner-assisted illumination corner lights automatically illuminate as the steering wheel deflects or the turn signal flashes, so the driver can immediately spot pedestrians near the corners, reducing accident rates. It consists of a separate halogen bulb and a small reflector mounted behind the parking light reflector to illuminate a sector of a radius of several meters.
Active steering headlights: Active Front-lighting System (AFS), also known as adaptive steering headlight system, can continuously adjust the headlights according to the steering wheel angle, vehicle yaw rate and driving speed. The front steering angle keeps the direction of the light in line with the current direction of the car to ensure optimal illumination of the road ahead and to provide the driver with the best visibility, thus significantly enhancing the safety of driving in the dark.
We have two type gear pumps: oil gear pump and bitumen gear pump. oil gear pumps are divided into helical gear pumps and circular gear pumps. gear oil pump usually be used to transfer lubricating oil, if pump with bronze gear, pump also been used to transfer diesel fuel oil. pump have large flow rate and high pressure,strong suction. bitumen gear pump have three material: cast iron, cast steel and stainless steel. bitumen gear pump can bear 300 degree high temperature, pump have heat insulation jacket, can injuction hot water, hot oil and steam in to jacket circulation, keep pump warm, to prevent asphalt crystallization.
