Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of automobile parts, and particularly relates to a high-light-efficiency ultra-narrow lens module, a vehicle lamp and a vehicle. BACKGROUND

[0002] As an important function of vehicle active safety, vehicle lamps can be divided into illumination function and signal function according to functions. The illumination function mainly provides illumination for the driver in the night or in poor lighting conditions, and the signal lamp mainly provides the driving signal of the vehicle for other drivers or pedestrians. The vehicle lamp with the illumination function is divided into a low beam (LB) and a high beam (HB); the low beam is used for the illumination of the road surface, and can avoid dazzling of the driver of the opposite vehicle on the two-way urban road, and the high beam is used for the highway or the rural road without street lamps. In actual use, the use frequency of the low beam is much higher than that of the high beam, so the illumination effect of the low beam is particularly important.

[0003] The LED lens is an important part of the vehicle lamp, and the traditional LED lens is usually a circle, has a large light-emitting area and a single shape, and is not conducive to the differentiation of the vehicle shape. With the rapid development of new energy vehicles, the shape of the vehicle lamp is becoming more and more novel, and the narrower and thinner lens is conducive to the design of the shape, so that the vehicle shape is more coordinated and more beautiful. However, the narrow module also brings another problem, that is, the optical utilization rate is low, and a higher optical system cost is needed to ensure the illumination effect. The optical utilization rate of the traditional circular lens low beam can reach about 45%, and the optical utilization rate of the narrow module (referring to the lens module with a Z-direction light-emitting port < 20 mm) can only reach 30% to 40%, and the smaller the light-emitting port, the lower the utilization rate. SUMMARY

[0004] Therefore, the present application aims to provide a high-light-efficiency ultra-narrow lens module, a vehicle lamp and a vehicle, which can realize more flexible shape design while ensuring a high optical utilization rate, and the optical utilization rate can reach more than 45% in the case of an ultra-narrow Z-direction light-emitting port of 10 mm.

[0005] The present application solves the above technical problems through the following technical means:

[0006] In a first aspect, the present application discloses a high-efficiency ultra-narrow lens module, comprising a mirror system and a lens system, wherein the mirror system comprises a low-beam mirror module and / or a high-beam mirror module, the low-beam mirror module corresponds to a low-beam lens module, and the high-beam mirror module corresponds to a high-beam lens module; the low-beam mirror module and the low-beam lens module cooperate to form a low-beam two-side static curve illumination optical assembly, a low-beam outer side illumination optical assembly, a low-beam central region illumination optical assembly, a low-beam outer side region illumination optical assembly and a low-beam inner side light type illumination optical assembly; and the high-beam mirror module and the high-beam lens module cooperate to form one or more high-beam lens optical assemblies.

[0007] In the technical solution, the low-beam two-side static curve illumination optical assembly forms a static curve illumination (SBL) light type of low beam, is mainly used for illuminating an area on both sides of the vehicle that is not easy to observe by a driver, can better discover pedestrians at a crossroad, can be lit at the same time in series with a main low-beam LED in circuit control, or can be controlled separately, and whether to be turned on or not is selected according to actual working conditions; the low-beam outer side illumination optical assembly is mainly responsible for light type area illumination on the outer side of the low beam; the low-beam central region illumination optical assembly collectively constitutes a low-beam central region light type and a 45-degree cutoff line; the low-beam outer side region illumination optical assembly is mainly responsible for light type area illumination on the outer side of the low beam; and the low-beam inner side light type illumination optical assembly collectively constitutes an inner side light type of the low beam. Through the above layout combination of the low-beam mirror module and the low-beam lens module, higher light efficiency can be obtained at an ultra-narrow light outlet, and the optical utilization rate can be more than 45%.

[0008] Further, an angle α between a light-out surface boundary of the lens system and the horizontal Y direction is 0-3°, and an angle β between a top view light-out surface of the lens system and the horizontal Y direction is 0-36°. In the technical solution, if the angle α between the light-out surface boundary of the lens system and the horizontal Y direction exceeds 3°, the optical utilization rate of the lens system will decrease; and if the angle β between the top view light-out surface of the lens system and the horizontal Y direction exceeds 36°, light rays will be totally reflected in the lens system, resulting in a decrease in light efficiency. It should be noted that the X direction in the present application refers to a thickness direction of the lens before and after the main viewing direction, the Y direction refers to a left-right width direction of the lens in the main viewing direction, and the Z direction refers to a height direction of the lens in the main viewing direction.

[0009] Further, an X-direction thickness T of the lens system is 5-40 mm. In the technical solution, the X-direction thickness of the lens system can be adjusted in the range of 5-40 mm according to modeling requirements, so that the modeling design of the entire vehicle lamp is more flexible.

[0010] Furthermore, the high-beam lens optical assembly includes a high-beam reflector and a high-beam lens that are matched together. The high-beam reflector is provided in multiple locations, and the high-beam lens has one or more optical surfaces. With this arrangement, the number of high-beam reflectors and the number of high-beam LEDs matched thereto can be appropriately increased or decreased based on performance requirements, achieving optimal performance and cost.

[0011] Furthermore, the low beam side static curve lighting optical assembly includes a first low beam reflector and a first low beam lens that are matched, the low beam outer lighting optical assembly includes a second low beam reflector and a second low beam lens that are matched, the low beam center area lighting optical assembly includes a third low beam reflector and a third low beam lens that are matched, a fourth low beam reflector and a fourth low beam lens that are matched, and a fifth low beam reflector and a fifth low beam lens that are matched, the low beam outer area lighting optical assembly includes a sixth low beam reflector and a sixth low beam lens that are matched, and the low beam inner light type lighting optical assembly includes a seventh low beam reflector and a seventh low beam lens that are matched, and an eighth low beam reflector and an eighth low beam lens that are matched. In this technical solution, the LED light sources that cooperate with each of the above-mentioned low beam reflectors and low beam lenses can be independently controlled by the controller of the vehicle lamp, and can be appropriately increased or decreased according to the required performance and cost requirements.

[0012] In a second aspect, the present invention further discloses a vehicle lamp comprising a circuit board, an LED light source, and the aforementioned lens module. The LED light source is mounted on the circuit board; the lens system and circuit board are both mounted on a reflector system. In this technical solution, the circuit board is used to mount the LED light source. Light emitted by the LED light source is then reflected and transmitted by the lens module before being emitted.

[0013] Furthermore, the LED light source includes a high-beam LED module and a low-beam LED module. The high-beam LED module includes a number of high-beam LED lamps equal to the number of high-beam reflector modules, and the low-beam LED module includes a number of low-beam LED lamps equal to the number of low-beam reflector modules.

[0014] Furthermore, a low-beam companion LED is mounted on the circuit board of the high-beam LED module. The low-beam companion LED in this technical solution can be a low-power white light, mounted on the same circuit board as the high-beam LED module and sharing optical components. Light emitted by the low-beam companion LED passes through a reflector and enters a lens, where it is refracted to form a companion light pattern. This light pattern, located below the HH horizontal line, does not affect the three-zone glare and super-brightness of the low beam. This design helps ensure that when the low beam is on, the high beam area is also illuminated, ensuring a continuous appearance and meeting low beam lighting regulations.

[0015] Further, a light shielding structure is arranged on the circuit board at the low beam LED module, and the light shielding structure protrudes from the circuit board by 0.8-1.0 mm. With the arrangement, the direct light of the low beam LED lamp can be shielded, so that the stray light does not affect the low beam regulation and the road surface effect.

[0016] Further, the focal point of the low beam reflector module coincides with the light emitting center of the low beam LED lamp as a first focal point, the light emitted by the low beam LED lamp converges to form a second focal point, and the second focal point is located 25-35 mm in front of the first focal point.

[0017] Further, the third focal point of the outer surface of the low beam lens module is located 20-25 mm behind the low beam LED lamp. With the arrangement, the third focal point is arranged behind the low beam LED, so that the light emission efficiency can be further improved, and a relatively clear low beam bright-dark cutoff line can be obtained.

[0018] Further, the fourth focal point of the inner surface of the low beam lens module is located infinitely far behind the low beam LED lamp, or is located 2.0 mm behind the low beam LED lamp. With the fourth focal point being located infinitely far behind the low beam LED lamp, the lateral width of the light pattern can be controlled. With the fourth focal point being located 2.0 mm behind the low beam LED lamp, the center brightness and 45-degree cutoff line of the low beam can be realized, so that a relatively high center brightness and a clear bright-dark cutoff line can be obtained.

[0019] Further, the vehicle lamp further comprises a heat sink, the reflector system is fixedly connected with the heat sink, and the circuit board is arranged between the reflector system and the heat sink. In the technical solution, the heat sink can dissipate heat for the circuit board and the LED light source mounted on the circuit board, so that the service life of the vehicle lamp is prolonged.

[0020] In a third aspect, the application further discloses a vehicle, which comprises a vehicle body and the lens module or the vehicle lamp.

[0021] The high light efficiency ultra-narrow lens module, the vehicle lamp and the vehicle have the following advantages.

[0022] 1. The low beam static curve lighting optical components on both sides of the present invention form the static curve lighting (SBL) light pattern of the low beam, which is mainly used to illuminate the areas on both sides of the vehicle that are difficult for the driver to observe, so as to better detect pedestrians at the intersection; the low beam outer lighting optical component is mainly responsible for lighting the light pattern area outside the low beam of the vehicle; the low beam center area lighting optical component, this group of optical components, together constitute the low beam center area light pattern and the 45-degree cut-off line; the low beam outer area lighting optical component is mainly responsible for lighting the light pattern area outside the low beam; the low beam inner light pattern lighting optical component, this group of optical components, together constitute the inner light pattern of the low beam; through the above-mentioned low beam reflector module and low beam lens module layout combination, higher light output efficiency can be obtained at the ultra-narrow light output port, and its Z-direction light output port can be as small as 10mm, which can achieve high optical utilization while achieving styling, and can reach more than 45%.

[0023] 2. The present invention sets the included angle α between the boundary of the light-emitting surface of the lens system and the horizontal Y direction to 0-3°, and the included angle β between the top-view light-emitting surface of the lens system and the horizontal Y direction to 0-36°. Such an installation angle of the lens system can avoid light reflection and further improve the light-emitting efficiency of the entire lens module; and within this angle range, a high optical utilization rate can be guaranteed, which is beneficial to the design of the headlight shape.

[0024] 3. The vehicle lamp of the present invention can further improve the light emission efficiency by specifically setting the positions of the first focus, the second focus, the third focus and the fourth focus, and at the same time obtain a clearer low beam and dark cut-off line, achieving multiple goals at one stroke.

[0025] 4. In the present invention, the LED light sources used in conjunction with the low-beam reflectors and low-beam lenses can be independently controlled by the headlight controller, and can be appropriately increased or decreased according to the required performance and cost requirements. The number of high-beam reflectors and the high-beam LEDs matched therewith can also be appropriately increased or decreased according to performance requirements to achieve optimal performance and cost.

[0026] 5. The headlight of the present invention has fewer parts, a small lens size, and less space occupancy. At the same time, it is compact in size, flexible in layout, and saves space. The cost does not increase compared to traditional lenses, and it takes into account styling, efficiency, performance, and cost. BRIEF DESCRIPTION OF THE DRAWINGS

[0063] Embodiment 2,

[0064] This embodiment is a kind of car light, as Figure 1As shown, the vehicle lamp includes a circuit board 3, a heat sink 4, an LED light source, and the lens module of the aforementioned embodiment 1. The LED light source is mounted on the circuit board 3. The reflector system 1 is fixedly connected to the heat sink 4, with the circuit board 3 positioned between the reflector system 1 and the heat sink 4. The lens system 2 and the circuit board 3 are both mounted on the reflector system 1. The LED light source includes a high-beam LED module and a low-beam LED module. The high-beam LED module includes a number of high-beam LED lamps 51 equal to the number of high-beam reflector modules 11, and the low-beam LED module includes a number of low-beam LED lamps 52 equal to the number of low-beam reflector modules 12.

The LED light source is attached to the circuit board 3. Lens system 2 is typically injection-molded from PC or PMMA. Reflector system 1 typically utilizes high-temperature PC, with partial aluminum plating. Circuit board 3 can be made of aluminum or copper, depending on the actual operating conditions. Heat sink 4 is typically die-cast or stamped aluminum.

It is then refracted by the high-beam lens module 21 to form a companion light pattern. This light pattern is located below the HH horizontal line and does not affect the glare and super brightness of the three zones of the low beam. This design helps to illuminate the high-beam area simultaneously when the low beam is illuminated, ensuring a continuous appearance and meeting low-beam lighting regulations.

[0066] like Figure 14As shown, a light-blocking structure 54 is provided on the circuit board 3 at the low-beam LED module. The light-blocking structure 54 protrudes above the circuit board 3 by 0.8-1.0 mm, with a height of 0.8 mm being selected in this embodiment. The light-blocking structure 54 blocks direct light from the low-beam LED 52, thereby preventing stray light from impacting low-beam regulations and road conditions. The focal point of the low-beam reflector module 12 coincides with the center of light emission of the low-beam LED 52 as a first focal point. Light emitted by the low-beam LED 52 converges to form a second focal point 55, located 25-35 mm in front of the first focal point, with a height of 30 mm being selected in this embodiment. A third focal point 56 on the outer surface 57 of the low-beam lens module 22 is located 20-25 mm behind the low-beam LED 52, with a height of 22 mm being selected in this embodiment. Positioning the third focal point 56 behind the low-beam LED significantly improves light emission efficiency and provides a clearer low-beam light cutoff line. The fourth focal point of the inner surface 58 of the low beam lens module 22 is located at infinity behind the low beam LED lamp 52, or at 2.0 mm behind the low beam LED lamp 52; locating the fourth focal point at infinity behind the low beam LED lamp 52 can be used to control the lateral width of the light pattern; locating the fourth focal point 2.0 mm behind the low beam LED lamp 52 can be used to achieve the center brightness and 45-degree cutoff line of the low beam, thereby obtaining a higher center brightness and a clear light and dark cutoff line.

[0067] In addition, the above-mentioned embodiment 1 and embodiment 2 are only examples of Figure 6 In the case where a group of low-beam LED lights 5252 and a group of high-beam LED lights 5151 are in a straight line, some similar variations not listed in this embodiment are also within the scope of protection; Figure 15 The lens module shown can be transformed into two lenses: single near (LB) + single far (HB). The size of a single lens is Z10mm*Y 100mm. Only the shape of the heat sink 4 needs to be changed. The optical parts can be borrowed and the parts can be disassembled. Figure 16 The lens module shown can be transformed into two low beams and two high beams. The size of a single lens is Z10mm*Y 50mm. The optical surfaces of its optical parts are uniformly designed in a modular manner. Figure 17 The variability shown is 4 low beams and 4 high beams, and the size of a single lens is Z10mm*Y 25mm. Thanks to our independently designed sub-optical system, a variety of combinations can be derived according to different demand scenarios, which will not be detailed here.
