Description

Technical Field

[0001] The utility model relates to the technical field of automobile lighting, and more specifically, to a matrix automobile lamp. Background Art

[0002] With the rapid development of the automotive industry and lighting technology, automotive headlights are playing an increasingly important role. Traditional lens headlights, due to their large vertical dimensions, are not suitable for styling and are difficult to meet people's personalized and diverse needs. Therefore, flat headlight modules have gradually become the mainstream design trend in the industry. Matrix headlights, due to their flatness, intelligence, personalization, and technological features, are becoming increasingly popular with customers and have become standard in mid- to high-end vehicle lighting systems.

[0028] The drawings in this utility model are for illustrative purposes only and are not to be construed as limiting the scope of this utility model. To better illustrate the following embodiments, some components in the drawings may be omitted, enlarged, or reduced in size, and do not represent the actual dimensions of the products. It is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted from the drawings.

[0029] Example 1

[0030] like Figures 1 to 4 As shown, this embodiment discloses a matrix automobile lamp, including a bracket 1, a low-beam lamp module 2 for realizing low-beam lighting and a high-beam lamp module 3 for realizing high-beam lighting, the low-beam lamp module 2 including a heat sink 21, a light source board 22 arranged above the heat sink 21, two LED illuminators 23 arranged on the upper surface of the light source board 22, two reflective cups 24 respectively covering the two LED illuminators 23, a first light-emitting lens 25 for emitting light from the two LED illuminators 23, and a reflector 26 arranged on the LED illuminators 23. A light-cutting mechanism 26 for forming a low-beam light pattern is provided on the path of the light. The first light-emitting lens 25 includes two first lens portions 251. The light-cutting mechanism 26 includes two light-blocking plates 261. The high-beam headlight module 3 is located obliquely behind the low-beam headlight module 2, and the height difference between the high-beam headlight module 3 and the low-beam headlight module 2 is less than 2.5 mm. The high-beam headlight module 3 includes at least one laser module 32. In this embodiment, the number of low-beam headlight modules 2 is 2, the number of high-beam headlight modules 3 is 1, and the two low-beam headlight modules 2 are arranged adjacent to each other.

[0031] In this embodiment, the bracket 1 is used to mount the low-beam headlight module 2 and the high-beam headlight module 3, facilitating the convenient installation of the entire matrix headlight on the vehicle. The low-beam headlight module 2 is used to achieve low-beam lighting, and the high-beam headlight module 3 is turned on when high-beam lighting is required to achieve high-beam lighting. In this embodiment, two LED light emitters 23 are provided, and both LED light emitters 23 are arranged above the heat sink 21. A light-cutting mechanism 26 having two light-blocking plates 261 is provided to block the light from the LED light emitters 23. A first light-emitting lens 25 having two first lens portions 251 is provided to emit light. This can not only maintain the flatness of the overall structure of the headlight, but also ensure that the headlight is bright enough when achieving low-beam lighting. The high-beam headlight module 3 is arranged obliquely behind the low-beam headlight module 2, and the height difference between the high-beam headlight module 3 and the low-beam headlight module 2 is less than 2.5 mm. Then, the high-beam headlight module 3 and the low-beam headlight module 2 are arranged in an oblique ladder-like manner. On the one hand, they can be flattened in height, and on the other hand, they can be more conveniently installed on the vehicle as a whole of the matrix headlight, with high adaptability and good heat dissipation effect. The high-beam headlight module 3 includes at least one laser module 32, which can fully ensure that the headlight has high brightness and a long irradiation distance when the high beam is illuminated. The heat sink 21 of the low-beam headlight module 2 is used to install other structures and facilitate heat conduction and heat dissipation of related structures. The light source board 22 supplies power to the LED light-emitting body 23. This embodiment adopts a matching assembly method of two low-beam headlight modules 2 and one high-beam headlight module 3, which can make the headlight better take into account both wide-range low-beam lighting and long-range high-beam lighting effects.

[0032] Furthermore, if Figure 6 As shown, the two light shields 261 of the light-cutting mechanism 26 are of the same size and are integrally formed. More specifically, in this embodiment, the light-cutting mechanism 26 further includes a solenoid valve 262, which drives the light shield 261 to cut in and out of the light path of the LED light source 23, thereby achieving the conversion of high and low beam light patterns.

[0033] Furthermore, if Figure 4 、 Figure 5 As shown, the two reflective cups 24 are also an integrally formed structure. The integrally formed structure is easy to process and install, can simplify the process and reduce costs.

[0034] Furthermore, the low-beam headlight module 2 is equipped with a cooling fan 27. The first light-emitting lens 25 and the cooling fan 27 are located at the front and rear ends of the low-beam headlight module 2, respectively. In this embodiment, the front and rear are referenced to the light emission direction of a matrix-type automotive headlight, with the light emitting direction of the headlight being the front, and the light emitting direction away from the headlight being the rear. Similarly, the rear portion described below is also referenced to the light emission direction of a matrix-type automotive headlight, with the end facing away from the light emission direction being the rear portion.

[0035] Furthermore, a circuit driving board 28 is provided below the heat sink 21 , and the circuit driving board 28 is used to supply power and drive control to the heat dissipation fan 27 , the light cutting mechanism 6 , and the light source board 22 .

[0036] Furthermore, if Figure 7 、 Figure 8 As shown, the high-beam headlight module 3 of this embodiment includes a heat sink 31, two parallel laser modules 32 mounted on the heat sink 31, and a second light-emitting lens 33 located in the light-emitting direction of the laser module 32. The second light-emitting lens 33 includes two second lens portions 331, which are arranged parallel to the arrangement of the two first lens portions 251. The two laser modules 32 provide higher brightness during high-beam illumination. The parallel arrangement of the two second lens portions 331 and the two first lens portions 251 creates a flat, nearly linear overall structure suitable for installation on most vehicle models.

[0037] More specifically, if Figure 9 As shown, the laser module 32 includes a laser 321 that emits laser light, a collimating lens 322, a diffuser 323, a converging lens 324, a wavelength conversion powder sheet 325, and a light-collecting lens 326 that are sequentially arranged along the optical path of the laser light. The collimating lens 322 is used to collimate the laser light, and the converging lens 324 converges the laser light onto the wavelength conversion powder sheet 325. The wavelength conversion powder sheet 325 converts at least part of the laser light into converted light.

[0038] More specifically, the laser module 32 also includes a housing 327 having a through-hole, with the laser 321 and the light-collecting lens 326 located at either end of the through-hole. The remaining components are mounted within the through-hole. Furthermore, a collimating lens sleeve 328 for mounting the collimating lens 322, a converging lens sleeve 329 for mounting the converging lens, and a light-collecting lens holder 3210 for mounting the light-collecting lens are also provided. A pressure plate 3211 for compressing the light-collecting lens 326 is also provided on the light-emitting surface of the light-collecting lens 326.

[0039] Furthermore, the high-beam headlight module 3 also includes a drive plate 34 and a lens holder 35 for securing the second light-emitting lens 33. The drive plate 34 is disposed between the laser module 32 and the second light-emitting lens 33 and within the lens holder 35. The drive plate 34 is provided with two escape holes for emitting light from the two laser modules 32. The drive plate 34, disposed between the laser module 32 and the second light-emitting lens 33, not only separates the two heat sources, the laser 321 and the drive plate 34, but also partially blocks the internal structure of the high-beam headlight module 3, preventing it from being visible through the second light-emitting lens 33.

[0040] Furthermore, the high beam light module 3 also includes a fan 36 and a cover plate 37. The fan 36 is arranged below the laser module 32. The cover plate 37 is a U-shaped structure. The cover plate 37 covers the top, bottom and tail of the high beam light module 3 so as to shield the top, bottom and tail of the high beam light module and make the shape more beautiful.

A light-cutting mechanism 26 for forming a low-beam light type is provided on the path of the light from the LED light-emitting body 23. The first light-emitting lens 25 includes two first lens portions 251. The light-cutting mechanism 26 includes two light-blocking plates 261. The high-beam headlight module 3 is located obliquely behind the low-beam headlight module 2, and the height difference between the high-beam headlight module 3 and the low-beam headlight module 2 is less than 2.5 mm. The high-beam headlight module 3 includes at least one laser module 32. In this embodiment, the number of the low-beam headlight module 2 and the high-beam headlight module 3 are both 1.

[0043] The only difference between this embodiment 2 and embodiment 1 is that the number of low beam headlight modules 2 is different from that in embodiment 1, and the brightness of the headlights will be lower than that of embodiment 1. The specific structure and working process of the low beam headlight module and the high beam headlight module are the same as those in embodiment 1 and will not be repeated here.

[0044] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the technical solution of the present invention, and are not intended to limit the specific implementation methods of the present invention.
