DETAILED DESCRIPTION

[0026] In order to facilitate the understanding of those skilled in the art, the present invention is further described below in conjunction with the embodiments and drawings, and the contents mentioned in the implementation modes are not intended to limit the present invention. The present invention is described in detail below in conjunction with the drawings.

[0027] Example 1

[0028] like Figures 1 to 4 As shown, a hyperbolic high-beam and low-beam integrated vehicle lamp provided in this embodiment comprises a lamp body 1, a first light source 112, a lens 3 and a light blocking mechanism 4, all of which are arranged on the lamp body 1. The lamp body 1 is further provided with a first curved mirror 5 and a second curved mirror 6. The first curved mirror 5 is located above the first light source 112 and the second curved mirror 6. One end of the second curved mirror 6 facing the lens 3 and one end of the first curved mirror 5 facing the lens 3 are respectively provided with notches 52. The first light source 112 is located in the second curved mirror 6.

[0029] When the utility model is working, the first curved mirror 5 is used to refract the light emitted upward by the first light source 112 to the lens 3, and the second curved mirror 6 is used to refract the light emitted by the first light source 112 to the surrounding to the lens 3. Specifically, since the first curved mirror 5 and the second curved mirror 6 are both provided with a notch 52, the notch 52 is the direction in which the first curved mirror 5 and the second curved mirror 6 refract the light, and the light can be emitted to the lens 3 after passing through the notch 52, and then emitted to the outside world after passing through the lens 3, so as to achieve the desired lighting effect.

[0030] In addition to providing a first curved mirror 5 to refract the light of the first light source 112, the utility model is also equipped with a second curved mirror 6 to refract the light emitted from the side of the first light source 112 that cannot be refracted by the first curved mirror 5, so that the light emitted by the first light source 112 can be more efficiently transmitted to the lens 3, so that under the premise that the brightness of the first light source 112 remains unchanged, the brightness of the utility model is made higher.

[0031] In this embodiment, a positioning portion 61 is provided at the top of the second curved mirror 6 , a positioning groove 51 is provided at the bottom of the first curved mirror 5 , the first curved mirror 5 is connected to the second curved mirror 6 , and the positioning portion 61 is inserted into the positioning groove 51 .

[0032] Specifically, connecting structures 62 are respectively provided on both sides of the second curved mirror 6 for fixing it to the lamp body 1; the first curved mirror 5 and the second curved mirror 6 are two independently manufactured components, and the two are fixed by gluing or other means; when fixing, the positioning part 61 and the positioning groove 51 need to be coordinated to achieve assembly, thereby ensuring the accuracy of the relative position between the two.

[0033] In this embodiment, the light blocking mechanism 4 includes a light blocking plate 41, a rotating shaft 42, a driving source 43 and an elastic member 44. The light blocking plate 41 is installed on the rotating shaft 42, the rotating shaft 42 is rotatably set on the lamp body 1, the driving source 43 is used to drive the rotating shaft 42 to rotate, and the elastic member 44 is set between the rotating shaft 42 and the lamp body 1.

[0034] In actual use, the driving source 43 is preferably a motor, and the elastic member 44 is a torsion spring. The driving source 43 controls the rotation of the shaft 42 according to the signal to drive the light shielding plate 41 to rotate, thereby changing the light path toward the lens 3 to achieve the switching between the high beam and low beam functions.

[0035] In this embodiment, the lamp body 1 is provided with a lamp heat dissipation module 9, which is arranged at the rear of the lamp body 1. The lamp heat dissipation module 9 is used to absorb the heat emitted by the first light source 112 and transfer it to the outside to ensure that the temperature of the first light source 112 is not too high when working, thereby ensuring the service life of the first light source 112.

[0036] In this embodiment, ventilation holes 10 are respectively provided on both sides of the lamp body 1 to further improve the heat dissipation effect of the utility model.

[0037] Example 2

[0039] The arrangement of the second light source 7 and the prism structure 8 enables the light emitted by the second light source 7 to be refracted by the prism structure 8 to the lens 3 when the high beam function is turned on, thereby increasing the brightness and ensuring higher lighting brightness and longer lighting distance under the high beam function.

[0040] Specifically, the number of the second light sources 7 is two, and the prism structure 8 includes a first prism 82, a first focusing cup, a second prism 83 and a second focusing cup.

The first prism 82 is installed on the top of the first focusing cup, and the second prism 83 is installed on the top of the second focusing cup. Both the first prism 82 and the second prism 83 face the lens 3.

[0041] The light from the two second light sources 7 is collected and guided by the first focusing cup or the second focusing cup and then photographed by the first prism 82 or the second prism 83, and refracted by the first prism 82 or the second prism 83 to ensure that the interference between the light from the two second light sources 7 is minimized, thereby ensuring the light utilization rate.

[0042] In this embodiment, the first prism 82 and the second prism 83 are arranged at an obtuse angle, and the angle between the first prism 82 and the second prism 83 is 135-165 degrees, so as to minimize the interference of light rays and the influence on the lighting effect.

[0043] In this embodiment, the prism structure 8 further includes a prism bracket 81 , and the first prism 82 , the second prism 83 , the first focusing cup and the second focusing cup are all mounted on the prism bracket 81 , and the prism bracket 81 is mounted on the lamp body 1 .

[0044] The prism bracket 81 is a component for assembling the prism structure 8 to the lamp body 1 , and it also achieves the effect of allowing the first focusing cup to cover the outside of the second light source 7 and the second focusing cup to cover the outside of another second light source 7 .

[0045] In this embodiment, the prism structure 8 further includes a prism heat dissipation module, which is installed on the lamp body 1 and located behind the prism structure 8. The prism heat dissipation module is used to absorb the heat emitted by the second light source 7 and transfer it to the outside.

[0046] Specifically, the lamp heat dissipation module 9 and the prism heat dissipation module are both heat dissipation fin structures.
