The front combination headlight of the vehicle is just like the eyes of a person. It plays a crucial role in the design of the exterior design of the entire vehicle. At the same time, as a main tool for night lighting, good working conditions play a crucial role in driving safety at night.

So how do you perform daily maintenance on the headlamp combination headlight of a combined truck? Here are some basic explanations for everyone from:

Causes of Headlamp Fog Generation 1. When the headlights are turned on during rainy days, the internal air of the headlights becomes hot due to the heat of the light source. On the contrary, the surface of the headlights is rapidly cooled due to rain erosion, and the difference in internal and external temperatures generated at the time causes the former Lights form inside the lamp.

2. When the car is being washed, the heat of the engine compartment will cause the lamp to become hot. At this time, the car wash will also have a temperature difference, resulting in internal fogging.

3, the root causes of fog, water droplets: 1 cubic meters of air, the temperature at 4 °C, the maximum moisture content can be accommodated is 6.36g; and when the temperature is 20 °C, 1 cubic meter of air can accommodate up to 17.50 vapor is 17.30 It can be seen that, at a certain temperature, the air can hold a certain amount of moisture, and when it reaches saturation, the excess water vapor will condense out, and enough water will condense to form fog or water droplets.

Water intake and normal judgment of fog 1. Check the state of moisture on the surface of the mask.

2. Check if the appearance of the parts is damaged when entering the water.

3, the rear cover assembly is normal.

4, whether parts are missing or damaged.

5, whether the abnormal changes in the wire.

Measures when fog is generated 1. When fog is generated on the windshield of a car, we will turn on the air-conditioning to eliminate fog. Similarly, when the current lamp produces fog, turn on the lights and the fog will slowly dissipate.

2. The fog generated inside the headlamps is not a quality problem but a normal phenomenon. Under normal circumstances, fog has little effect on the performance of the headlights.

To prevent the generation of lamp fog and water removal method 1. Car washing or scouring of the lamp should be avoided when the headlights are turned on (rain weather is inevitable and no emphasis is placed on it).

2. Avoid deep road sections where the vehicle is driving water (the wading depth depends on the height of vehicle lighting design and the vehicle wading speed).

3, to avoid the lamp cover, turn the lamp holder is not installed in place after replacement; should clean the inner surface of the corresponding seal apron, aprons can not have sediment or debris, aprons or installation errors caused by the lamp does not seal Yan, leading to water, fog formation.

4, when the lamp found that the inner surface of the formation of fog beads, should try to avoid continued use in the rain environment, wait until the weather improves, while turning on the far and near light, under normal circumstances, the vehicle will naturally disappear 30-60 minutes fog (occasionally there will be fog can not Completely dissipated, depending on the water vapor density during the formation of the fog and the excessively fast speed of the lamp, resulting in an appropriate extension of vehicle travel time or vehicle speed.

When the vehicle is running in a poor environment for a long time, the driver feels that the vehicle illumination has dropped significantly, indicating that the lamp mask has accumulated certain dust or silt. At this time, the lamp mask should be cleaned in time (so as not to interfere with the normal illumination of the lamp and affect the heat dissipation. The lamp is deformed. The front mask of the lamp can be cleaned with a high pressure water gun, but the high pressure water gun can not be used on the back side of the bumper to prevent the lighting accessories from falling (dust-proof, air-breathable or other) to cause the water to enter the lamp in the future.

Replace bulb 1, low light bulb replacement When the vehicle is implemented on bumpy roads for a long time, the service life of the lamp will drop sharply, so you need to replace the lamp regularly; when replacing the lamp, you should use the standard manufacturer's standard H124V70W lamp, such as ORSAN, PHILIPS, and use it rigorously. Non-standard high power, large wattage, modified xenon lamps and other practices. After the bulb is replaced, the surface of the inner apron of the rear cover and the corresponding edge of the shell should be cleaned to avoid dust and sediment and other debris from contacting the sealing ring, resulting in reduced sealing performance of the lamp and screwing it into place in the correct manner.

2, high-beam lamp replacement:

The replacement of the lamp and location is the same as the replacement of the low beam lamp. The precautions are the same.

3, turn signals, daytime driving lights to replace the light bulbs:

The turn signal and daytime driving light bulbs are standard 24V21WP21W type bulbs. Please change the specified standard bulbs at the regular service station. Rigorous replacement of high-power or non-standard installation size bulbs, otherwise it will cause the internal overheating of the lamp to cause other defects. The installation of the lamp holder should be done so as to prevent the product from becoming airtight due to dust or debris between the gasket and the housing.

The light type of the luminaire is adjusted by adjusting the low beam. Firstly, adjust the electric switch in the driver's cab interior, adjust the light modulation ESC to the lowest point, use the longer Phillips screwdriver to align the manual light adjustment screw, and turn the two adjustment screws counterclockwise. Make the near-beam line move up to a reasonable position; adjust the light pattern clockwise to reduce, and the distance of the front illumination becomes shorter (the adjustment height should be strictly in accordance with national standards or national qualified vehicle inspection plants).

The adjustment method of high beam and low beam is the same. The difference is that the high beam has no power switch.

Good maintenance and maintenance of the headlights not only guarantees the appearance of the headlights, but also guarantees the safety of use. We hope that the majority of our joint truck fans will keep in mind the above maintenance tips. Be considerate and caring for the product. The joint truck will reward you for a good job and life.
