The laser tube 11 is the light source of fog lamp assembly, the laser tube 11 is connected with the circuit board subassembly 30, the circuit board subassembly 30 provides working circuit for the laser tube 11, in order to control the laser tube 11 to begin to give out light or stop giving out light according to the instruction, the laser that the laser tube 11 launches is behind lens subassembly 12, it is the collimation laser to receive the beam shaping, the laser beam after the collimation is diffused by the astigmatism piece subassembly 20 again, make some light spot diffusion be oval facula, the laser beam after the diffusion launches to the external world, satisfy the optical property of fog lamp assembly, furthermore, the circuit board subassembly 30 is installed in base 200, thereby make whole lamp structure 100 install in base 200, base 200 is used for firm lamp structure 100.
The fog lamp assembly in this embodiment is applied to in the car, the back fog lamp of specially adapted car, and base 200 installs on the car for the fog lamp light that back fog lamp launched is laser, has the characteristic that the penetrability is strong because of the laser, thereby can provide farther warning discovery distance for rear vehicle, pedestrian, and the visible distance of fog lamp light becomes long, and then prolongs rear personnel's reaction time, improves driving safety nature.
In addition, the laser also has polarization, under extreme weather conditions such as dense fog, heavy rain, strong sand and dust, the polarization of the laser and the common sense that natural light is unpolarized light are utilized, a clearer and variable optical profile can be provided for a backward observer under the condition of natural environment light, the contrast ratio of a rear fog lamp of a vehicle to the natural environment is increased, and the driving safety of the vehicle under the extreme environment conditions is improved.
Preferably, the fog lamp assembly is installed at the tail of the automobile, and the included angle between the straight line where the laser tube 11 is located and the straight line extending from the head to the tail of the automobile is greater than 0 degree and smaller than 90 degrees.
The fog lamp assembly in the first embodiment is more suitable for the rear fog lamp of an automobile, can be installed at the tail of the automobile, and can enable the included angle between the straight line where the laser tube 11 is located and the straight line extending from the head to the tail of the automobile to be larger than 0 degrees and smaller than 90 degrees when the fog lamp assembly is installed, namely the laser emitted by the laser tube 11 inclines downwards, so that the fog lamp light of the rear fog lamp irradiates on the ground, and the fog lamp light is prevented from irradiating the eyes of a rear observer.
Correspondingly, when the base 200 is installed at the tail of the automobile, the base 200 is provided with a groove for installing the lamp structure 100, and the plane where the notch of the groove is located can be inclined towards the plane where the bottom of the automobile is located, so that the included angle between the straight line where the laser tube 11 is located and the straight line extending from the head to the tail of the automobile is larger than 0 degree and smaller than 90 degrees.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
