The low-beam LED light source module 1 and the high-beam LED light source module 2 are arranged on the upper and lower sides of the same heat dissipation substrate, and emit light beams to form low-beam light distribution and high-beam light distribution respectively. Due to the limitation of the brightness of the current LED light source, there is usually a problem of obviously insufficient central illumination. For this reason, the prior art proposes a solution to add a direct-beam module to supplement the low-beam lighting or high-beam lighting. However, since the installation of the direct-beam module requires a separate direct-beam module mounting bracket and an installation space, the volume of the entire headlight is increased, and the cost and structural complexity are increased. In addition, since the direct-beam module is far away from the main heat dissipation bracket, the heat conduction speed of the direct-beam module is slow and the heat dissipation efficiency is low.

DETAILED DESCRIPTION

[0022] The present invention is described in detail below in conjunction with the accompanying drawings.

[0023] like Figure 2-3 As shown, the present invention provides a dual-light lens headlight, comprising: a first heat dissipation bracket 10, a first light source module 20 and a second light source module 30 arranged on the first heat dissipation bracket 10, a shading device 80 corresponding to the first light source module 20 and the second light source module 30, and a second heat dissipation bracket 40 arranged in front of the first heat dissipation bracket 10 along the light path, a direct-light module 50 and a lens 60 are sequentially arranged on the second heat dissipation bracket 40 along the light path, and also includes a direct-light heat dissipation module 70 corresponding to the direct-light module 50, and the direct-light module 50 does not block the light projected from the first light source module 20 and the second light source module 30 to the lens 60. Specifically, the second heat dissipation bracket 40 is located in front of the first heat dissipation bracket 10 along the optical path, and is used to install the direct module 50 and the lens 60 and to guide the heat generated by the direct module 70, thereby increasing the heat conduction channel area of ​​the direct module 70. At the same time, the direct heat dissipation module 70 is provided to dissipate heat for the direct module 50 separately, and there is no need to share the first heat dissipation bracket 10 with the first light source module 20 and the second light source module 30 for heat dissipation, thereby greatly improving the heat dissipation efficiency. In addition, the direct module 50 and the lens 60 are simultaneously installed on the second heat dissipation bracket 40, and there is no need to separately set up a direct module 50 installation bracket and installation space, thereby effectively reducing the production cost and installation complexity as well as the volume of the entire vehicle lamp.

[0024] In this embodiment, the second heat dissipation bracket 40 is made of aluminum material with high thermal conductivity, which has fast heat conduction and light material. Of course, it can also be made of other thermal conductive materials.

[0025] In the present application, the light emitted by the first light source module 20 and the second light source module 30 is distributed by the shading device 40 and then transmitted through the internal space of the second heat dissipation bracket 40 to the lens 60 to form a low beam distribution, and the light emitted by the direct module 50 is directly projected onto the lens 60 to supplement the low beam or high beam. Compared with the existing dual-light lens headlights, the first light source module 20 and the second light source module 30 used in this article can form a low beam distribution with a larger lateral range, more uniform brightness distribution and higher brightness, so as to more clearly see the conditions around the vehicle and the road surface, and improve driving safety.

[0026] like Figure 4a As shown, the cross section of the second heat dissipation bracket 40 is annular, and a mounting platform 410 is provided inside the second heat dissipation bracket 40, and the direct-emitting module 50 is provided on the mounting platform 410. The second heat dissipation bracket 40 is an annular bracket with openings at both ends, and a mounting platform 410 for mounting the direct-emitting module 50 is provided on one side thereof. The annular structure of the second heat dissipation bracket 40 can greatly increase the heat conduction area and further improve the heat dissipation efficiency. The mounting platform 410 is a beam structure formed by vertically extending from one side inside the second heat dissipation bracket 40, and the beam structure does not block the light transmitted from the first light source module 20 and the second light source module 30 to the lens 60.

[0027] like Figure 4b As shown, the direct-emission heat dissipation module 70 includes a plurality of heat dissipation fins 710 disposed on the side of the mounting platform 410 different from the direct-emission module 50. The heat dissipation fins 710 are located at the rear of the direct-emission module 50 and are used to quickly dissipate heat from the direct-emission module 50. Preferably, the direct-emission heat dissipation module 70 also includes a heat dissipation fan 720 corresponding to the heat dissipation fins 710, a horizontal cover plate 90 is provided on the first heat dissipation bracket 10, the heat dissipation fan 720 is provided on the horizontal cover plate 90, and a plurality of vents 910 corresponding to the heat dissipation fan 720 are provided on the horizontal cover plate 90. It can be seen that in this embodiment, the direct-emission module 50 is cooled by a combination of the second heat dissipation bracket 40, the heat dissipation fins 710 and the heat dissipation fan 720, and the heat dissipation efficiency of the direct-emission module 50 can be increased by more than 50% compared with the installation method in the prior art.

[0028] Preferably, the lens 60 is arranged at one end of the second heat dissipation bracket 40 away from the first heat dissipation bracket 10, and adjustment space is provided around the lens 60 and between the second heat dissipation bracket 40. In this embodiment, the lens 60 is installed at the front end of the second heat dissipation bracket 40 along the optical path, and the two are fixed by glue, and there is a gap between the outer circumference of the lens 60 and the second heat dissipation bracket 40. After the assembly of the headlight is completed, due to the installation error of the optical components, a dimming process is required. At this time, the relative position between the lens 60 and the second heat dissipation bracket 40 is adjusted so that the emitted light spot meets the set light distribution requirements. After the dimming process is completed, the relative position of the lens 60 and the second heat dissipation bracket 40 is fixed. Compared with the existing headlights that need to adjust multiple components such as the light source module, the direct module, and the lens module during the dimming process, this solution only needs to adjust the position of the lens 60, without adjusting multiple components, which is simpler to operate and more efficient.

[0029] In this embodiment, a positioning ring 420 for fixing the lens 60 is further provided at one end of the second heat dissipation bracket 40 corresponding to the lens 60. After the position of the lens 60 is fixed, the positioning ring 420 is mounted on the second heat dissipation bracket 40 from one end of the lens 60 to prevent the lens 60 from shifting relative to the second heat dissipation bracket 40 and ensure assembly accuracy.

[0030] Preferably, the first light source module 20 and the second light source module 30 are located on the same side of the first heat dissipation bracket 10, and the shading device 80 includes a first shading member 810 and a second shading member 820 corresponding to the light outlets of the first light source module 20 and the second light source module 30, that is, the first shading member 810 corresponds to the light outlet of the low beam module 20, and the second shading member 820 corresponds to the light outlet of the high beam module 30. In this embodiment, the low beam module 20 and the high beam module 30 are arranged on the same side of the first heat dissipation bracket 10, which can increase the thickness of the heat dissipation substrate and improve the heat dissipation efficiency of the two light sources. The first shading member 810 and the second shading member 820 can be installed separately, or the shading sheets therein can be connected as one, and controlled by the same driving motor 830. The shading sheets of the first shading member 810 and the second shading member 820 are both arc-shaped structures and the upper edges have a cutoff line shape that meets the low beam light type.

[0031] Preferably, the first light source module 20 includes a first light source 210 and a first reflective bowl 220 corresponding thereto, and the second light source module 30 includes a second light source 310 and a second reflective bowl 320 corresponding thereto, and the first light source 210 and the second light source 310 can be LED light sources or laser light sources, and the first reflective bowl 220 can be connected as a whole or set separately. The first light source 210 and the second light source 220 can be LED light sources or laser light sources, and the first light source 210 and the second light source 220 can be light sources of the same specifications or light sources of different specifications. Figure 3 As shown, in this embodiment, the first light source 210 and the second light source 310 adopt LED light sources of the same specifications, and the two reflective bowls 220 are connected as one. Of course, the first light source 210 and the second light source 310 can also adopt laser light sources, that is, a combination of a semiconductor laser and a phosphor sheet is adopted, wherein the phosphor sheet is arranged at the focus of the corresponding reflective bowl, and the reflective bowl is provided with a through hole for passing the laser beam emitted by the semiconductor laser.

[0032] Preferably, the lens 60 includes a first partition for emitting light from the direct-emission module 50, a second partition 620 for emitting light from the first light source module 20, and a third partition 630 for emitting light from the second light source module 30. When the first light source module 20 and the second light source module 30 are located on the same side of the first heat dissipation bracket 10, the second partition and the third partition 630 of the lens 60 are arranged along the width direction of the vehicle lamp, and the sizes of the second partition and the third partition 630 can be the same or different, and can be designed according to the light beams emitted by the first light source module 20 and the second light source module 30.

[0033] Preferably, the direct-light module 50 includes one or more direct-light sources 510. When there are multiple direct-light sources 510, the multiple direct-light sources 510 are controlled individually or simultaneously, and the first subarea of ​​the lens 60 includes small lenses 611 corresponding to the direct-light sources 510. In one case, there is one direct-light source 510, and there is also one small lens 611 in the first subarea, corresponding to the position of the direct-light source 510. In the low-beam state or the high-beam state, the direct-light source 510 is turned on for fill-in light according to actual needs. In another case, there are two direct light sources 510, which are controlled separately. In this case, there are also two small lenses in the first partition, which correspond one to one with the direct light sources 510. The direct light source 510 adopts an LED light source or a laser light source, and the two direct light sources 510 adopt the same light source or different light sources. In the low beam state, one of the direct light sources 510 is turned on for fill light, and in the high beam state, the other direct light source 510 is turned on for fill light; or the two direct light sources 510 are connected in series on the same circuit and controlled by the same switch. When fill light is needed, such as in the high beam state, the two direct light sources 510 are turned on at the same time through the switch for fill light, thereby increasing the brightness of the central light spot. In another case, there are three direct light sources 510, and there are also three corresponding small lenses 611, which correspond one to one with the direct light sources 510. Figure 3As shown, the direct light source 510 can be an LED light source or a laser light source, and the brightness and divergence angle of the three direct light sources 510 can be the same or different. For example, the direct light source 510 located in the middle and the direct light sources 510 located on both sides use different light sources. When in the low beam state, the direct light source 510 located in the middle is turned on for fill light, and when in the high beam state, the direct light sources 510 located on both sides are turned on for fill light. The three direct light sources 510 can also be turned on at the same time to fill light for the low beam state or the high beam state. When the light source luminous area or divergence angle of the direct light source 310 is different, the sizes of the corresponding multiple small lenses 611 can also be different. The above-mentioned several fill light methods are only examples. Of course, other methods can also be used to control the opening and closing of multiple direct light sources 510 to achieve the desired effect.

[0034] Preferably, the direct-light module 50 further includes a collimating lens 520 disposed between the direct-light source 510 and the lens 60. The collimating lens 520 corresponds to the direct-light source 510 one-to-one and is used to collimate the light beam emitted by the direct-light source 510 to achieve a focusing effect and improve the brightness of the fill-light spot. When there are multiple direct-light sources 510, there are also multiple collimating lenses 520, which can be fixed separately or integrally formed, such as Figure 3 shown.

[0035] Preferably, the dual-light lens headlight further comprises a heat dissipation module disposed on a side of the first heat dissipation bracket 10 away from the second heat dissipation bracket 40 , and the heat dissipation module comprises an aluminum profile heat sink 101 and a fan 102 for dissipating heat from the first light source 210 and the second light source 310 .

[0036] Although the embodiments of the present invention are described in the specification, these embodiments are only for reference and should not limit the protection scope of the present invention.
