Description

Technical Field

[0001] The utility model relates to the technical field of automobile lamps, in particular to an automobile fog lamp with three low beams and four lenses. Background Art

[0002] The fog lights used in cars are usually installed on the front and rear of the car. They are used to illuminate the road and provide safety warnings when driving in rainy and foggy weather. They can provide road lighting for the driver, improve the visibility of the driver and surrounding traffic participants, and provide great help to the driver's vision in rainy and foggy weather conditions, which directly affects the driver's driving safety.

[0003] As an auxiliary lighting system of automobile lights, fog lamps are installed at a relatively low position. The existing fog lamp structure is mainly composed of a shell, a lamp bead circuit board, a dual-light lens, and a lamp cup. The dual-light lens is installed at the front end of the shell, and the lamp bead circuit board and the reflective cup are fixed inside the shell.

[0004] The existing fog lamp structure has the following shortcomings:

[0005] 1) The auxiliary lighting area of ​​the fog lamp is mainly concentrated in its low beam state. The traditional fog lamp dual-beam lens uses the lamp cup and the two convex spherical surfaces of the dual-beam lens as the high beam auxiliary light for optical processing. However, the high beam does not play a good auxiliary role in the application scenario of the fog lamp. The low beam brightness is not high enough, which is not conducive to the driver to see the road conditions clearly in harsh environments such as rain and fog, which is easy to affect the driver's driving safety and even the driver's life safety;

[0006] 2) The existing heat dissipation method of the lamp bead circuit board is mainly through the shell, and usually heat dissipation holes are opened on the shell. The heat dissipation of the lamp bead circuit board is very slow, and most of the lamp beads on the lamp bead circuit board are high-power lamp beads, which easily cause a large amount of heat to be retained in the shell and difficult to discharge in time, resulting in the lamp bead circuit board temperature being too high and easily damaging the circuit board, which in turn causes the internal temperature of the fog lamp to be too high, easily damaging various components of the fog lamp and affecting the service life of the fog lamp. In addition, opening heat dissipation holes will affect the waterproof performance of the fog lamp and easily cause water to enter the fog lamp. Utility Model Content

[0043] The working principle of the utility model automobile fog lamp is as follows:

[0044] ① When the car is about to turn on the low beam, the low beam LED lamp bead 111 of the low beam module 11 is lit, and the light emitted by the low beam LED lamp bead 111 of the low beam module 11 is reflected by the reflective cup 13. When the light passes through the light-changing mechanism 4, part of the light is blocked, and then the light is concentrated by the low beam main lens spherical surface 21 of the lower hemisphere of the optical lens 2 to form a low beam light type with a cutoff line; at the same time, the light emitted by the low beam auxiliary LED lamp bead 121 and the second low beam auxiliary LED lamp bead 122 will be collected and redistributed by the first low beam auxiliary spherical surface 22 and the second low beam auxiliary spherical surface 23 of the upper hemisphere of the optical lens 2, thereby enhancing the light intensity in the low beam center area and enhancing the lighting effect;

[0045] ② When the car turns on the high beam, while ensuring the low beam module 11 in "①" works, the dimming mechanism 4 starts to work, opens the light blocking jumper, and completely opens the light of the low beam LED lamp bead 111 blocked by the dimming mechanism 4, forming a high beam light effect with a central strong light area.

[0046] The light beams emitted by the low beam auxiliary LED lamp bead 121 and the second low beam auxiliary LED lamp bead 122 overlap after passing through the first low beam auxiliary spherical surface 22 and the second low beam auxiliary spherical surface 23 of the upper hemisphere of the optical lens 2, forming a low beam auxiliary light pattern evenly distributed at 40 degrees to the left and right and 10 degrees up and down, such as Figure 7 The light distribution area is located in the area directly in front of the car that is normally visible to the driver. The automobile fog lamp of the utility model enhances the brightness of this area, which is more conducive to the driver seeing the road conditions clearly.

[0047] The light emitted by the low-beam LED lamp bead 111 is reflected by the reflector cup 4 and then projected to the light collecting area of ​​the reflector cup 4. When the light passes through the dimming mechanism 4, it will project a high-beam state and a low-beam state in front of it according to its on state and off state. When the dimming mechanism 4 is not working, it is in the low-beam state. Figure 8 As shown, when the light-changing mechanism 4 is not working, it is in the high-beam state. Fig. 9 As shown, when the low beam of the first low beam auxiliary LED lamp bead 121 and the second low beam auxiliary LED lamp bead is turned on, the low beam state is as follows Fig.10 As shown, the high beam state of the first low beam auxiliary LED lamp bead 121 and the second low beam auxiliary LED lamp bead when the low beam is turned on is as follows Fig.11 shown.

[0048] The above description has been a detailed description of the present invention. The above description is only a preferred embodiment of the present invention and should not limit the scope of implementation of the present application. That is, all equivalent changes and modifications made within the scope of the present application should still fall within the scope of the present invention.
