fog lights (foglamp) also called Spotlight main purpose is to ensure the driver’s line of sight and lighting of the road when driving rain and fog weather, but it is also a special lamp. It is characterized by the average can provide a very large area of illumination, the light of soft, level of detail, the color saturation is superb. General Automotive fog lamps are mounted on the front and rear of the car. However, fog is made of a special flash head, the flash tube before reflecting glass, all the light output by the light transmission diffusion reflector after reflection. Fog lamps can only be installed in a position slightly lower than the headlight position the front of the bumper of the car, because of the low visibility fog, the driver’s line of sight is limited. Light travel distance can be increased, in particular the yellow fog light penetration, which can increase the visibility of the driver and surrounding traffic participants, so that cars and pedestrians to find each other at a longer distance.
1. fog effect
Function
fog is to strengthen the rain and fog days lighting bulbs yellow and white, white light due to poor penetration, so a white car light yellow lights often require high light than about 25%. Fog light reflected by the cup constraints within the envelope, the irradiatedBefore the bottom of the vehicle diagonally to ensure that the driver can see the road condition in front of the vehicle to be seen up close and opposite, so pay attention to the installation position fog lamps can only be in the following bumper, body position closest to the ground, to ensure that fog effect, if installed high position, can not penetrate rain and fog lights to illuminate the situation on the ground, it is likely to cause dangerous.
visibility in fog or rain affected by the weather to allow vehicles saw the car is large, so the fog light source needs to have a stronger penetration. General vehicle is halogen fog lamps, halogen fog lights higher than the xenon fog lamps. The main purpose is to ensure that in bad weather the driver’s line of sight, and to ensure that others can see you, but now there are many companies, the purpose of the installation of fog before just to make more beautiful bumper, fog lights and therefore the choice the quality is poor. And headlights, except replacement of sufficient brightness fog, the fog select a xenon HID is a good choice.
2. fog Category
Since the anti-fog high brightness, high penetration without diffuse reflection due to the fog, it can effectively prevent the occurrence of the proper use of accidents. In foggy weather, front fog lights are usually used together.
1. The front fog
the front fog lamps are generally bright white, front fog lamps and fog lamps flag has little difference between the front fog lights line flag is down, action front fog lamps are not illuminated, but to provide a high brightness light scattering, the intensity of the light source to penetrate fog, alert the driver with the opposite, although capable of illuminating a small area, but ifNormal use, will be sufficient across the eyes dazzled. In this case, open front fog lights is an immoral act, is not recommended under normal circumstances, but only in case of fog. Even the heavy rain, the only need low-beam lights, fog will not give you any help.
2. After the rear fog light
is a red fog lights, rear fog lights staring the vehicle to see a few seconds, not tell the existence of the brake lights. And, light scattered light brake lights, fog light and then a part of parallel light, directly behind the driver, the brightness of the rear fog lamp + 21W 5W dual brake lights brighter light filament, such case, open the rear fog lamp, it will only lead to rear-end. If the evening, this time in the fast lane on the road, you’ll find both sides of the rear-view mirror inside the car has been vague, and accidentally, it may have overlooked one, this time, is the time to turn on the lights .
Do not wait until the day completely dark, this is a period of time, is most prone to dangerous time. Rain, because the vehicle side window glass of water, so that both sides of the rear-view mirror is basically useless, and this time if you open beam lights, will help anyone find you. Light near the design specifications, it is necessary to provide sufficient illuminance of the road, but there must be strict control of the irradiation direction of the beam, the main beam such as a 1.2 percent gradient. Dimming requirements, it is relying on this slope, so that the light shines only on the ground, rather than someone else’s eyes.
3. Fog Note
1. The design of the rear fog lamps, the purpose of driving the vehicle more visible to prompt fog whereReduce rear-end accidents. However, no fog generally do not use fog lights, front fog lamps without shades, lights make the car appear more dazzling, but some drivers will not only use the front fog lamps, rear fog lights are turned on even together. Perhaps it is because the larger rear fog lamp power, will form the back of the car driver glare light, it is easy to cause eye fatigue, affecting traffic safety.
2. The fog lamp switch general third gear, the gear is off 0, a first speed control front fog lights, fog control the second gear. Front fog lights work, front fog lights when opened two tranches of work together when opening a file.
3. Whether the front fog lamps or rear fog lamps, they do not light up, then it indicates that the lamp has been burned down, to be replaced. But if not completely broken, but the decrease in brightness, red and dim lighting, it may be a precursor to failure, thereby reducing the level of illumination is also safe driving significant risks.
There are several
4. The reason for the reduced luminance, and most typically is laminated on a glass or dirt astigmatism mirror lamps, then only needs to be done with a cloth or lens paper to clean the dirt removal . Another reason is the decline in the ability to charge the battery, power shortage caused by bright enough, so you need to replace the battery. Another possibility is that the aging wires or too small, resulting in an increase in resistance thus affecting power supply, this situation not only affects the work of the bulb, serious and even lead to overheat and cause a fire line.
