Among the many parts of a car, Car Fog Light has become a loyal partner of drivers in bad weather conditions with its unique functions and design. As an important part of the car lighting system, fog lights not only improve the driver's field of vision in low visibility environments, but also an important guarantee for driving safety.
The original intention of the design of Car Fog Light is to provide strong penetrating lighting in bad weather conditions such as fog, rain, and snow to help drivers identify the road conditions ahead. Its core lies in the synergy of light source, reflector, light distribution mirror and sunshade. The bulbs mostly use halogen or LED technology. The power of halogen bulbs is usually 55W, while LED is favored for its high efficiency and long life. The filament of the light source is located at the focus of the reflector parabola, and is reflected by the reflector to form a parallel beam of light. The light distribution mirror is responsible for diffusing and refracting the light beam to form a horizontal beam that meets regulatory requirements, while blocking visible light in the upper and lower directions to reduce the light film phenomenon caused by diffuse reflection.
Fog lights are mainly divided into front fog lights and rear fog lights. The front fog lamp is usually installed under the front bumper of the vehicle, at a lower position so that the light can penetrate the fog; the rear fog lamp is located at the rear of the vehicle, in the form of a red warning light, with a brightness higher than that of ordinary taillights, which is easy for the following vehicles to identify. According to the vehicle configuration, fog lamps can be divided into fixed and adjustable types. The latter allows the driver to adjust the beam angle according to actual needs to further enhance the lighting effect.
With the advancement of technology, fog lamp technology is also constantly updated. Early fog lamps mostly used halogen bulbs. Although the penetration is acceptable, the energy consumption and life are limited. In recent years, LED fog lamps have gradually become the mainstream of the market due to their high brightness, low power consumption, long life and fast response. For example, OSRAM LED multi-function fog lamps not only have lighting effects, but can also be used as daytime running lights during the day. In foggy weather, they automatically switch to fog lamp mode, which greatly improves driving safety.
Although fog lamps are good, improper use may also bring safety hazards. In weather conditions where visibility is less than 200 meters, the front fog lamps and rear fog lamps should be turned on to improve the visibility of the vehicle. However, it should be noted that the rear fog lamp has a high power and long-term use will cause visual interference to the driver of the following car. Therefore, it should be turned off in time after visibility improves. It is very important to regularly check the working condition of the fog lamp, including whether the bulb is burned out, whether the circuit is intact, whether the reflector and the light distribution mirror are clean and undamaged, etc. Once a fault is found, it should be replaced or repaired immediately to ensure that the fog lamp is always in the best working condition.
