Description

Technical Field

[0001] The present application relates to the technical field of vehicle lamps, and in particular to a vehicle lamp module and a vehicle. Background Art

[0002] In the related art, the high beam light shape (light spot) of LED dual-light lens headlights is circular, oblate or rectangular. This type of light spot has great deficiencies in driving experience and vision of the road ahead. First, this type of light spot cannot achieve high beam road illumination at a large distance when in high beam, which makes the road ahead of the driver insufficiently bright. The driver needs to concentrate his vision and try to find obstacles that may appear in the dark ahead. Maintaining this state for a long time can easily make the driver tired, thus affecting driving comfort and driving safety; secondly, this type of light spot has great defects in illuminating road signs, especially high road signs above highways during driving. Specifically, the illumination height of this type of light spot is not enough, and there is no gradient tail light extension in the height direction, which makes it easy to miss the road signs. When installing the lights, if the high beam is raised, although the road signs can be illuminated, it is too bright, the glare is too strong and dazzling, but this installation method will make the low beam paving insufficient, which is not conducive to driving safety.

[0026] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0027] In the related art, the high beam light shape (light spot) of LED dual-light lens headlights is circular, oblate or rectangular. This type of light spot has great deficiencies in driving experience and illuminating the road ahead. First, this type of light spot cannot achieve high-beam road illumination at a large distance when in high beam, which makes the road ahead of the driver insufficiently bright, and requires the driver to concentrate his eyesight and try to find obstacles that may appear in the dark ahead. Maintaining this state for a long time can easily make the driver tired, thus affecting driving comfort and driving safety; secondly, this type of light spot has great defects in illuminating road signs, especially high road signs above highways during driving. Specifically, the illumination height of this type of light spot is not enough, and there is no gradient tail light extension in the height direction, which makes it easy to miss the road signs. When installing the headlights, if the high beam is raised, although the road signs can be illuminated, it is too bright, the glare is too strong and dazzling, but this installation method will make the low beam paving insufficient, which is not conducive to driving safety.

[0028] In view of this, an embodiment of the present application proposes an automobile lamp module to effectively solve the aforementioned problem.

[0029] See also Figure 1 and Figure 2 As shown, an embodiment of one aspect of the present application discloses a car headlight module, which can effectively solve the problem of insufficient headlight illumination height; at the same time, it can also effectively solve the problem of insufficient brightness of the nearby road surface caused by raising the high beam when installing the headlight, thereby improving driving comfort and driving safety.

[0030] The following will be combined Figures 1 to 4 The automobile lamp module disclosed in the embodiment of the present application is specifically explained and illustrated.

[0031] like Figures 1 to 4 The automobile lamp module includes a high-beam reflector cup 110 (not shown in the figure) and a light-emitting module. The high-beam reflector cup 110 is symmetrically arranged about a first plane. The inner side surface of the cup body of the high-beam reflector cup 110 is formed with a reflective surface 111 that cooperates with the light-emitting module. The reflective surface 111 includes a first reflective curved surface 1111, a second reflective curved surface 1112 and a third reflective curved surface 1113. The first reflective curved surface 1111 is located in the middle and lower part of the inner side surface, the second reflective curved surface 1112 is arranged on one side of the first reflective curved surface 1111, and the second reflective surface 111 is located in the middle and upper part of the inner side surface, the third reflective curved surface 1113 is arranged on both sides of the first reflective curved surface 1111 and the second curved surface, and the first reflective curved surface 1111 and the second reflective curved surface 1112 are smoothly transitioned with the third reflective curved surface 1113 respectively.

[0032] The first plane is Figure 4 FF plane in.

[0033] In the automotive lamp module of the above embodiment, the reflective surface 111 in the high beam reflective cup 110 is formed by fitting a first reflective curved surface 1111 , a second reflective curved surface 1112 and a third reflective curved surface 1113 .

[0034] In one embodiment, the high beam reflector 110 is installed on the upper side of the light emitting module, and the light emitting module is located below the inner side of the high beam reflector 110. After the light emitting module is working, the first reflective curved surface 1111 can irradiate the collected light to the upper part of the high beam spot, the second reflective curved surface 1112 can irradiate the collected light to the lower part of the high beam spot, and the third reflective curved surfaces 1113 on both sides can irradiate the light collected on the left and right sides to the middle and upper part of the high beam spot, so that a tall high beam shield-shaped spot can be obtained, which can effectively solve the problem of insufficient illumination height of the headlight; at the same time, the second reflective curved surface 1112 can irradiate the collected light to the lower part of the high beam spot, which can effectively solve the problem of insufficient brightness of the nearby road surface caused by raising the high beam when installing the headlight, thereby improving driving comfort and driving safety.

[0035] It is worth understanding that the light emitting module is arranged on the first plane to ensure that the left and right sides of the obtained far light spot are symmetrical, thereby avoiding brightness differences between the left and right sides of the far light spot.

[0036] In some embodiments of the present application, see Figure 2 and Figure 3 , the curvature of the first reflective curved surface 1111 is greater than the curvature of the second reflective curved surface 1112. In other words, the curvature of the first reflective curved surface 1111 is greater than the curvature of the second reflective curved surface 1112, and after the light emitted by the light-emitting module is reflected by the first reflective curved surface 1111 and the second reflective curved surface 1112, the light will be stratified to a certain extent. At the same time, the first reflective curved surface 1111 is arranged close to the bottom of the high-beam reflector cup, and the second reflective curved surface 1112 is located on the upper side of the light-emitting module, so that the light reflected by the first reflective curved surface 1111 and the second reflective curved surface 1112 can be irradiated to the upper and lower parts of the light spot respectively, which can increase the height of the high-beam spot and also help to ensure the brightness of the upper and lower parts of the high-beam spot.

[0037] In some embodiments of the present application, see Figure 3 , the curvature of the profile of the reflective surface 111 on the first plane gradually decreases from the first reflective curved surface 1111 to the second reflective curved surface 1112. In other words, the curvature of the reflective surface 111 gradually decreases from the first reflective curved surface to the second reflective curved surface 1112, so that the light can converge near the light spot, thereby improving the brightness of the distant light spot.

[0038] In some embodiments of the present application, the curvature of the first reflective curved surface 1111 is greater than the curvature of the third reflective curved surface 1113 .

[0039] In some embodiments of the present application, the area of ​​the first reflective curved surface 1111 is one quarter of the area of ​​the entire reflective surface 111. In this way, the brightness of the upper part of the far light spot can be guaranteed.

[0040] In some embodiments of the present application, see Figures 2 to 4 , the area of ​​the third reflective surface 111 is two quarters of the area of ​​the entire reflective surface 111. Specifically, the third reflective curved surface 1113 includes two parts, one of which is located on one side of the first reflective curved surface 1111, and the other is located on the other side of the first reflective curved surface 1111. The two parts of the third reflective curved surface 1113 respectively irradiate the light collected from the left and right sides to the middle and upper part of the far light spot. At the same time, the light reflected by the two parts of the third reflective curved surface 1113 can be staggered by a certain distance from the light reflected by the first reflective curved surface 1111, thereby increasing the width of the far light spot.

[0041] In one possible implementation, see Figure 4 , the two third reflective curved surfaces 1113 are symmetrically arranged about the first plane. Wherein, the dotted line FF is the projection of the first plane.

[0042] In some embodiments of the present application, the reflective surface 111 is an electroplated surface to form mirror reflection, thereby improving the reflection effect and ensuring the brightness of the distant light spot.

[0043] Another aspect of the present application provides a car, comprising the car light module as described above.

[0044] In the automobile of this embodiment, the reflective surface 111 in the cup body of the high beam reflective cup 110 of the automobile lamp module is fitted by a first reflective curved surface 1111, a second reflective curved surface 1112 and a third reflective curved surface 1113, wherein the first reflective curved surface 1111 can irradiate the collected light to the upper part of the high beam spot, the second reflective curved surface 1112 can irradiate the collected light to the lower part of the high beam spot, and the third reflective curved surfaces 1113 on both sides can irradiate the light collected on the left and right sides to the middle and upper part of the high beam spot. In this way, a tall high beam shield spot can be obtained, which can effectively solve the problem of insufficient illumination height of the lamp; at the same time, it can also effectively solve the problem of insufficient brightness of the nearby road surface caused by raising the high beam when installing the lamp, thereby improving driving comfort and driving safety.

[0045] In one embodiment, see Figure 5 and Figure 6 As shown, Figure 5 This is the existing 3-inch round lens-high beam effect diagram, where the illumination at 25 meters is: 313.666lx / (the illumination at 5 meters is 7825lx), the left and right angles are 90 degrees, and the angle below the cutoff line is 19 degrees; Figure 6This is a schematic diagram of the high beam effect of the automobile headlight module in one embodiment of the present application, wherein the diagram shows a 3-inch round lens-high beam effect diagram, the illumination at 25 meters is: 336.27lx / (5 meters illumination is 8406lx), and the left and right angles are 90 degrees. By comparison, it can be seen that the high beam illumination of the automobile headlight module in the embodiment of the present application is higher and the high beam effect is better.

[0046] In another embodiment, see Figure 7 and Figure 8 , Figure 7 This is the existing 3-inch square lens-high beam effect diagram, where the illumination at 25 meters is: 297.871lx / (5 meters illumination is 7425lx), the left and right angles are 90 degrees, and the angle below the cutoff line is 20 degrees; Figure 8 This is a schematic diagram of the high beam effect of the automobile headlight module in one embodiment of the present application; wherein, the figure shows the high beam effect of a 3-inch square lens, the illumination at 25 meters is: 332.407lx / (the illumination at 5 meters is 8300lx), and the left and right angles are 90 degrees. By comparison, it can be seen that the high beam illumination of the automobile headlight module in this embodiment is higher and the high beam effect is better.
