Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of automobile parts, and in particular to a high-light-efficiency ultra-narrow lens module, a car lamp and a vehicle. Background Art
[0002] As an important function of vehicle active safety, headlights can be divided into lighting function and signal function according to their functions. The lighting function mainly provides lighting for the driver at night or in road conditions with poor lighting conditions, and the signal light mainly provides driving signals for other drivers or pedestrians. Headlights with lighting functions are divided into low beam (LB) and high beam (HB); used for road lighting, low beam is used for two-way urban roads to avoid dazzling other drivers, and high beam is used for highways or rural roads without street lights. In actual use, the frequency of use of low beam is much higher than that of high beam, so the lighting effect of low beam is particularly important.
[0003] LED lens is an important part of automobile headlights. Traditional LED lens is usually a circle with a large luminous area and a single shape, which is not conducive to the differentiation of vehicle shape. With the rapid development of new energy vehicles, the shape of headlights is becoming more and more new. Narrower and thinner lenses are conducive to the design of the shape, making the vehicle shape more coordinated and more beautiful. However, narrow modules also bring another problem. The low optical utilization rate requires a higher optical system cost to ensure the lighting effect. The optical utilization rate of traditional circular lens low beam can reach about 45%, while the optical utilization rate of narrow modules (generally referring to lens modules with a Z-direction light outlet <20mm) can only reach 30% to 40%. The smaller the light outlet, the lower the utilization rate. Summary of the invention
[0004] In view of this, the purpose of the present invention is to provide a high-light-efficiency ultra-narrow lens module, a car light and a vehicle, which can achieve more freedom and flexibility in styling design while ensuring a higher optical utilization rate. When the Z-direction light outlet can be made ultra-narrow at 10 mm, the optical utilization rate reaches more than 45%.
[0005] The present invention solves the above technical problems by the following technical means:
[0006] In the first aspect, the present invention discloses a high-light-efficiency ultra-narrow lens module, comprising a reflector system and a lens system, wherein the reflector system comprises a low-beam reflector module and / or a high-beam reflector module, wherein the lens system corresponding to the low-beam reflector module is a low-beam lens module, and the lens system corresponding to the high-beam reflector module is a high-beam lens module; the low-beam reflector module and the low-beam lens module cooperate to form a low-beam static curve lighting optical component on both sides, a low-beam outer lighting optical component, a low-beam center area lighting optical component, a low-beam outer area lighting optical component and a low-beam inner light type lighting optical component; the high-beam reflector module and the high-beam lens module cooperate to form one or more high-beam lens optical components.
[0007] In this technical solution, the static curve lighting optical components on both sides of the low beam 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. In terms of circuit control, it can be connected in series with the main low beam LED and light up at the same time, or it can be controlled separately, and whether to turn it on or not can be selected according to the actual working conditions; the low beam outer lighting optical component is mainly responsible for the lighting of 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 cutoff line; the low beam outer area lighting optical component is mainly responsible for the lighting of the light pattern area outside the low beam; the low beam inner light type lighting optical component, this group of optical components together constitute the inner light pattern of the low beam. Through the above-mentioned combination of the low beam reflector module and the low beam lens module layout, a higher light output efficiency can be obtained at the ultra-narrow light outlet, and the optical utilization rate can reach more than 45%.
[0008] Furthermore, the angle α between the boundary of the light-emitting surface of the lens system and the horizontal Y direction is 0-3°, and the angle β between the light-emitting surface of the lens system when viewed from above and the horizontal Y direction is 0-36°. In the present technical solution, if the angle between the boundary of the light-emitting surface of the lens system and the horizontal Y direction exceeds 3°, the optical utilization rate of the lens system will decrease; if the angle between the light-emitting surface of the lens system when viewed from above and the horizontal Y direction exceeds 36°, the light will be totally reflected inside the lens system, resulting in a decrease in light extraction efficiency. It should be noted that the X direction in the present invention refers to the thickness direction of the lens before and after in the main viewing direction, the Y direction refers to the left and right width direction of the lens in the main viewing direction, and the Z direction refers to the height direction of the lens in the main viewing direction.
[0009] Furthermore, the thickness T of the lens system in the X direction is 5 mm to 40 mm. The thickness T of the lens system in the X direction in the technical solution can be adjusted within the range of 5 mm to 40 mm according to the design requirements, which can make the design of the entire headlight more free and flexible.
[0010] Furthermore, the high beam lens optical assembly includes a high beam reflector and a high beam lens that are matched, the number of the high beam reflectors is multiple, and the number of optical surfaces of the high beam lens is one or more. With such a configuration, the number of high beam reflectors and high beam LEDs matched therewith can be appropriately increased or decreased according to performance requirements, thereby 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, 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 side 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 the above-mentioned low beam reflectors and low beam lenses can be independently controlled by the controller of the vehicle light, 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, which includes a circuit board, an LED light source and the above-mentioned lens module, wherein the LED light source is mounted on the circuit board; and the lens system and the circuit board are both mounted on the reflector system. In this technical solution, the circuit board is used to mount the LED light source, and after the LED light source emits light, it is reflected and transmitted by the lens module and finally 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 lamp is arranged on the circuit board at the high-beam LED module. The low-beam companion LED lamp in the technical solution can be a low-power white light, which is installed on the same circuit board as the high-beam LED module and shares optical components with the high-beam LED module. The light emitted by the low-beam companion LED lamp enters the lens through the reflector, and then refracts through the lens to finally form a light pattern that is lit up. This light pattern is located below the HH horizontal line and will not affect the glare and super brightness of the low beam's 3 zones; this design helps to light up the high-beam area at the same time when the low beam is lit, ensuring the appearance effect of continuous light emission, while meeting the lighting regulations for the low beam.
[0015] Furthermore, a light blocking structure is provided on the circuit board at the low beam LED module, and the light blocking structure protrudes from the circuit board by 0.8-1.0 mm. The technical solution is arranged in this way to block the direct light of the low beam LED lamp, thereby preventing stray light from affecting low beam regulations and road surface effects.
[0016] Furthermore, the focus of the low-beam reflector module coincides with the light emission center of the low-beam LED lamp as a first focus, and the light emitted by the low-beam LED lamp converges to form a second focus, which is located 25-35 mm in front of the first focus.
[0017] Furthermore, the third focus of the outer surface of the low beam lens module is located 20-25 mm behind the low beam LED lamp. The technical solution is set in this way, and the third focus is set behind the low beam LED, which can further improve the light emission efficiency and obtain a clearer low beam cut-off line.
[0018] Furthermore, the fourth focal point of the inner surface of the low beam lens module is located at infinity behind the low beam LED lamp, or at 2.0 mm behind the low beam LED lamp. The technical solution places the fourth focal point at infinity behind the low beam LED lamp to control the lateral width of the light pattern; places the fourth focal point 2.0 mm behind the low beam LED lamp to achieve the center brightness and 45-degree cutoff line of the low beam, thereby obtaining a higher center brightness and a clear light-dark cutoff line.
[0019] Furthermore, the headlight further comprises a radiator, the reflector system is fixedly connected to the radiator, and the circuit board is arranged between the reflector system and the radiator. In this technical solution, the arrangement of the radiator can dissipate heat for the circuit board and the LED light source mounted on the circuit board, thereby extending the service life of the headlight.
[0020] In a third aspect, the present invention further discloses a vehicle, comprising a vehicle body and the above-mentioned lens module or headlight.
[0021] The high light efficiency ultra-narrow lens module, vehicle lamp and vehicle of the present invention have the following advantages:
[0022] 1. The low beam static curve lighting optical components on both sides of the present invention form a low beam static curve lighting (SBL) light pattern, 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 the lighting of 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 the lighting of the light pattern area outside the low beam; the low beam inner light type 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, a higher light output efficiency can be obtained at an ultra-narrow light output port, and its Z-direction light output port can be 10mm, which can achieve a high optical utilization rate while achieving the shape, and can reach more than 45%.
[0023] 2. In the present invention, the angle between the boundary of the light-emitting surface of the lens system and the horizontal Y direction is α=0~3°, and the angle between the top-view light-emitting surface of the lens system and the horizontal Y direction is β=0~36°. Such an installation angle of the lens system can avoid the reflection of light 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 dark cut-off line, thereby achieving multiple goals at one stroke.
[0025] 4. In the present invention, the LED light sources coordinated with the low-beam reflectors and the low-beam lenses can be independently controlled by the controller of the vehicle lights, 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 the best 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 the shape, efficiency, performance, and cost. BRIEF DESCRIPTION OF THE DRAWINGS

[0063] Embodiment 2,
[0064] This embodiment is a vehicle lamp. 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 above-mentioned embodiment 1. The LED light source is installed on the circuit board 3. The reflector system 1 is fixedly connected to the heat sink 4. The circuit board 3 is arranged between the reflector system 1 and the heat sink 4. The lens system 2 and the circuit board 3 are both installed 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. Specifically, the lens system 2 and the reflector system 1 are assembled by welding or snap-fitting. The reflector system 1 and the heat sink 4 are fixed by a positioning structure and screws. The circuit board 3 is sandwiched between the reflector system 1 and the heat sink 4. The circuit board 3 and the heat sink 4 are assembled with a positioning structure to ensure assembly accuracy. The circuit board 3 is affixed with an LED light source. The lens system 2 is generally made of PC or PMMA material injection molding, the reflector system 1 is generally made of high-temperature PC and the surface needs to be partially aluminum-plated, the circuit board 3 can be made of aluminum substrate or copper plate according to the actual working conditions, and the heat sink 4 is usually made of aluminum die-casting or stamping. The light emitted by the LED light source is reflected by the reflector system 1, and then reaches the lens system 2 and is refracted and emitted to obtain the light type and luminous intensity we need.
[0065] like Fig.13 As shown, a low beam companion LED lamp 53 is arranged on the circuit board 3 at the high beam LED module. The low beam companion LED lamp 53 can be a low-power white light, which is installed on the same circuit board 3 as the high beam LED module and shares optical components with the high beam LED module. The light emitted by the low beam companion LED lamp 53 passes through the high beam reflector module 11 and enters the high beam lens module 21, and then is refracted by the high beam lens module 21 to finally form a light pattern that is accompanied by lighting. This light pattern is located below the HH horizontal line and will not affect the glare and super brightness of the low beam's three zones; this design helps to light up the high beam area at the same time when the low beam is lit, ensuring the appearance effect of continuous lighting, while meeting the lighting regulations for the low beam.
[0066] like Fig.14As shown, a light blocking structure 54 is provided on the circuit board 3 at the low beam LED module, and the light blocking structure 54 protrudes above the circuit board 3 by 0.8-1.0 mm, and 0.8 mm is selected in this embodiment; the light blocking structure 54 can block the direct light of the low beam LED lamp 52, thereby preventing stray light from affecting low beam regulations and road surface effects. The focus of the low beam reflector module 12 coincides with the light emission center of the low beam LED lamp 52 as the first focus, and the light emitted by the low beam LED lamp 52 converges to form a second focus 55, and the second focus 55 is located 25-35 mm in front of the first focus, and 30 mm is selected in this embodiment. The third focus 56 of the outer surface 57 of the low beam lens module 22 is located 20-25 mm behind the low beam LED lamp 52, and 22 mm is selected in this embodiment; in this way, the third focus 56 is set behind the low beam LED, which can further significantly improve the light emission efficiency, and at the same time, a relatively clear low beam light-dark cutoff line can be obtained. 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 embodiments 1 and 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 deformation modes not listed in this embodiment are also within the scope of protection; Fig.15 The lens module shown can be transformed into two lenses, one near (LB) and one far (HB), with the size of a single lens being Z10mm*Y 100mm. Only the shape of the heat sink 4 needs to be changed, and the optical parts can be borrowed by simply disassembling the parts. Fig.16 The lens module shown can be transformed into 2 low beams and 2 high beams, and the size of a single lens is Z10mm*Y 50mm. The optical surfaces of its optical parts are uniformly designed in a modular manner; Fig.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 repeated here one by one.
