The installation position of the fog lamp can only be below the bumper and the position closest to the ground of the vehicle body to ensure the function of the fog lamp, and if the position is too high, the light cannot penetrate the rain and fog to illuminate the ground (the fog is generally thin below 1 m), which is easy to cause danger.
[0003] Therefore, the maintenance of the fog lamp is very important during use, and if the maintenance structure of the fog lamp structure is not reasonably designed, the fog lamp needs to be replaced frequently, which increases the use cost of the vehicle owner and cannot guarantee the driving safety. In addition, the fog lamp is generally used in cooperation with the headlamp to improve the safety performance.
[0004] With the LED light source being very popular in the market at present, the LED light source has been widely applied to automobile signal lamps, and the optical requirements of the LED light source as the headlamp are higher than those of the signal lamp, and the heat dissipation problem has been a bottleneck in research and development. In addition, the light of the LED light source is easy to disperse in heavy fog, and the penetration is insufficient. Therefore, it is difficult to develop a fog lamp module with good heat dissipation and strong penetration. UTILITY MODEL CONTENTS
