Description

Technical Field

[0001] The present invention relates to the technical field of vehicle lamps, and in particular to a small opening module, a vehicle lamp and a vehicle. Background Art

[0002] Both high and low beams are used by cars to illuminate at night. The difference between the two is that high beams have a higher angle and a longer distance, while low beams have a lower angle and a shorter distance. High beams are generally used when driving in open or dimly lit areas such as highways or in the suburbs, which can expand the field of vision. However, when there is a car on the opposite side and you need to meet it, you need to switch to low beams for safety and courtesy. In addition, low beams are generally used when driving on city roads to prevent the high angle of the high beams from affecting the sight of drivers of oncoming vehicles and pedestrians on the road, causing safety hazards.

[0003] At present, most high and low beam lamps adopt integrated modules, but most of the high and low beam lamp modules on the market still adopt traditional structural design, and the traditional high and low beam module structural design cannot meet the requirements of automobile high and low beam lamps for module performance to a certain extent. Moreover, the upper and lower openings of the lenses of the high and low beam lamp modules currently used in automobiles are mostly large, which is not conducive to meeting the requirements of automobiles for the changeable shapes of headlights.

[0004] LED lamps are now commonly used light sources due to their advantages of high luminous efficiency, small luminous area, low energy consumption, low manufacturing cost, and long service life. They are also widely used in high beams, low beams, and turn signals on cars. Currently, most LED lamps in the automotive lighting industry use LED module units. However, due to the large openings at the upper and lower ends of the commonly used LED lamp modules, they cannot meet the module size requirements of automotive headlights to a certain extent, which is not conducive to the miniaturization of the modules and the needs of changing the shapes of automotive headlights. However, for a long time, those skilled in the art have been unable to find a suitable technical solution to change the larger openings at the upper and lower ends of the LED lamp modules, resulting in great limitations in the shape of the headlights.

[0005] In view of this, it is necessary to provide a new type of vehicle light module solution. Summary of the invention

[0006] The first aspect of the technical problem to be solved by the present invention is to provide a small-opening module, which is reasonably designed, can increase the utilization efficiency of light energy, and can reduce the upper and lower openings of the module lens, which is more conducive to the miniaturization of the module and can achieve the optimization of high and low beam types.

[0007] The second problem to be solved by the present invention is to provide a vehicle lamp which can effectively realize miniaturization, has a uniform light beam, and has a high efficiency in utilizing light energy.

[0008] The third technical problem to be solved by the present invention is to provide a vehicle whose headlights can be effectively miniaturized, with high efficiency in light energy utilization, which is beneficial to the beauty and flexible shaping of the vehicle body.

[0009] In order to achieve the above-mentioned purpose, the first aspect of the present invention provides a small opening module, including a high-beam light source, a low-beam light source, a reflector and a lens, wherein the lens includes a low-beam lens portion and a high-beam lens portion; the low-beam light beam generated by the low-beam light source is reflected to the low-beam lens portion through the reflector; an optical conversion element is provided between the high-beam light source and the lens for projecting the high-beam light beam generated by the high-beam light source to the high-beam lens portion.

[0010] Preferably, the reflector and the low-beam light source are arranged above the high-beam light source, and the low-beam lens portion extends downward to form the high-beam lens portion.

[0011] Preferably, the reflective surface of the reflector is an ellipsoidal surface or a quasi-ellipsoidal surface, the reflector includes a first focus close to the reflective surface and a second focus far from the reflective surface, and the low-beam light source is arranged at the first focus.

[0012] Preferably, a shading plate for forming a low-beam cut-off line is provided between the low-beam light source and the lens.

[0013] Preferably, the shading plate is arranged at the second focus.

[0014] Preferably, the high beam light source adopts LED lamps, and the number of the LED lamps is 3-7.

[0015] Preferably, the high-beam light sources are dispersedly mounted on the radiator.

[0016] Preferably, the optical conversion element is a focusing module or a Fresnel lens.

[0017] Preferably, each of the high-beam light sources corresponds to a corresponding focusing unit of the focusing module; or the focusing module includes a plurality of concentrators, and each of the high-beam light sources corresponds to a corresponding concentrator; or each of the high-beam light sources corresponds to a corresponding Fresnel lens.

[0018] In a second aspect, the present invention provides a vehicle lamp, comprising the small opening module as described in any one of the first aspects.

[0019] In a third aspect, the present invention provides a vehicle, comprising the small opening module described in any one of the first aspect and the vehicle light described in the second aspect.

[0020] Through the above technical scheme, the small opening module of the present invention adopts the optical conversion element and the high beam light source to cooperate with each other, and the light generated by the high beam light source is projected to the lens through the optical conversion element, which can make the light more concentrated, and in the present invention, the high beam and the low beam share a lens, so that the upper and lower openings of the lens can be reduced, which is more conducive to the miniaturization of the module; at the same time, the use of the optical conversion element can also improve the efficiency of light utilization, and the same light energy can be converted into a better lighting effect, thereby improving the market competitiveness of the module. The small opening module of the present invention forms the low beam through the low beam light source, the reflector and the low beam lens part, and forms the high beam through the high beam light source and the optical conversion element.

[0033] The specific implementation of the present invention is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the present invention, and is not used to limit the present invention.

[0034] In the description of the present invention, it is necessary to understand that the terms "upper", "lower", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0035] In the description of the present invention, the term "front" refers to a position indicated by a direction in which light is emitted, and "rear" refers to a position opposite thereto.

[0036] In the basic implementation mode of the present invention, Figure 1-Figure 4 As shown, the present invention provides a small opening module, including a high beam light source 1, a low beam light source 2, a reflector 3 and a lens 4, wherein the lens 4 includes a low beam lens portion 41 and a high beam lens portion 42; the low beam light beam generated by the low beam light source 2 is reflected to the low beam lens portion 41 through the reflector 3; an optical conversion element 6 is provided between the high beam light source 1 and the lens 4 for projecting the high beam light beam generated by the high beam light source 1 to the high beam lens portion 42.

[0037] When the small opening module of the above basic technical scheme of the present invention is working, when it is necessary to irradiate low beam, the high beam light source 1 is turned off, and the low beam light source 2 is turned on. The low beam light beam generated by the low beam light source 2 is reflected by the reflective surface of the reflector 3 and then projected to the low beam lens part 41, and then refracted by the low beam lens part 41 to form low beam. When it is necessary to irradiate high beam, the low beam light source 2 and the high beam light source 1 are turned on, and the high beam light beam generated by the high beam light source 1 is projected to the high beam lens part 42 through the optical conversion element 6, and then emitted through the high beam lens part 42 to form high beam. The high beam part of the small opening module of the above basic scheme of the present invention is provided with an optical conversion element 6 between the high beam light source 1 and the lens 4. The optical conversion element 6 and the high beam light source 1 cooperate with each other to project the high beam light beam to the high beam lens part 42, so that the light generated by the high beam light source 1 can be more concentrated. At the same time, the high beam and the low beam in the present invention share a lens 4, which is more conducive to the miniaturization and beauty of the module; the optical conversion element 6 used in the present invention can make the light generated by the high beam brighter. Moreover, the present invention controls the high beam part and the low beam part separately, and can adjust the structures of the high beam part and the low beam part respectively so that the high beam and the low beam can achieve the optimal light type.

[0038] In a preferred embodiment of the present invention, the reflector 3 and the low-beam light source 2 are disposed above the high-beam light source 1 , and the low-beam lens portion 41 extends downward to form the high-beam lens portion 42 .

[0039] More preferably, the reflecting surface of the reflector 3 may be an ellipsoid or a quasi-ellipsoid surface. Generally, an ellipsoid surface has two focal points. In the present invention, the two focal points are respectively a first focal point close to the reflecting surface and a second focal point far from the reflecting surface, and the low-beam light source 2 is arranged at the first focal point. The quasi-ellipsoid surface may be any structure or shape similar to the shape of the ellipsoid surface. The low-beam light beam generated by the low-beam light source 2 is reflected downward under the action of the reflecting surface of the reflector 3 and refracted through the low-beam lens portion 41 to form a low-beam light beam. When the reflector 3 and the low-beam light source 2 are installed above the high-beam light source 1, the reflector 3 will reflect the low-beam light beam downward, shortening the distance between it and the high-beam light beam, thereby further reducing the upper and lower end openings of the module, which is more conducive to the miniaturization of the module. Moreover, the use of a reflector 3 with a reflecting surface of an ellipsoid or a quasi-ellipsoid surface and the low-beam light source 2 arranged in the focal area of ​​the ellipsoid or the quasi-ellipsoid surface can reflect the light generated by the low-beam light source 2 to the low-beam lens portion 41 as much as possible, thereby making more effective use of the low-beam light source 2.

[0040] In one embodiment of the present invention, a shading plate 5 for forming a low-beam cut-off line is provided between the low-beam light source 2 and the lens 4. Preferably, the shading plate 5 is provided at the second focal point. This design allows as many low-beam beams as possible to be projected to the outside through the low-beam lens portion 41, and there is no need to use a solenoid valve to switch the shading plate 5, thus eliminating the structure of the solenoid valve, effectively reducing noise, and increasing the working reliability of the module and the installation accuracy of the shading plate 5.

[0041] In a preferred embodiment of the present invention, the high beam light source 1 uses LED lamps, and the number of the LED lamps is 3-7. Multiple LED lamps can be dispersedly installed on the low beam circuit board to facilitate centralized control of the LED lamps. Since there are many LED lamps, if the LED lamps are installed together, the temperature of the LED lamps will be too high, causing light decay, and even affecting the service life of the LED lamps. Therefore, the high beam light source 1 needs to be dispersedly installed on the radiator 7. It is also possible to first install the LED lamp on the low beam circuit board, and then install the low beam circuit board on the radiator 7.

[0042] The optical conversion element 6 can be any optical conversion element 6 that can project the light generated by the high-beam light source 1 onto the high-beam lens portion 42. Preferably, the optical conversion element 6 can be selected as a focusing module or a Fresnel lens. Of course, inspired by the technical concept of the present invention, those skilled in the art can also think of other similar optical conversion elements 6 or their modified structures.

[0043] Specifically, each of the high-beam light sources 1 corresponds to a corresponding focusing unit of the focusing module; or the focusing module includes a plurality of concentrators, and each of the high-beam light sources 1 corresponds to a corresponding concentrator; or each of the high-beam light sources 1 corresponds to a corresponding Fresnel lens. More specifically, the focusing module may be a concentrator, the number of which is consistent with the number of LED lamps of the high-beam light source 1, and each concentrator is correspondingly arranged between the high-beam light source 1 and the lens 4. The focusing module may also be one, and a plurality of focusing units may be provided in the focusing module, and each focusing unit is arranged corresponding to the LED lamp. Regardless of whether the focusing module is set to one or more, the focusing unit or concentrator in front of the high-beam light source 1 can project the light generated by the high-beam light source 1 onto the high-beam lens portion 42.

[0044] In a relatively optimized embodiment of the present invention, Figure 1 and Figure 2 As shown, it includes a high-beam light source 1, a low-beam light source 2, a lens 4 and a reflector 3, the low-beam light source 2 is placed at the focus of the reflector 3, and the reflector 3 and the low-beam light source 2 are placed above the high-beam light source 1, and a shielding plate 8 is provided between the high-beam light source 1 and the low-beam light source 2 to prevent the high-beam light source 1 and the low-beam light source 2 from affecting each other; the high-beam light source 1 is an LED lamp, and there are 3-7 LED lamps, and the multiple LED lamps are dispersedly arranged on the high-beam circuit board, and the high-beam circuit board and Installed on the radiator 7; a lens 4 is arranged on one side of the high-beam light source 1 and the low-beam light source 2, the upper part of the lens 4 is a low-beam lens part 41, which is shaped like a convex lens, and the low-beam lens part 41 extends downward to form a high-beam lens part 42; a visor 5 is arranged at one of the two focal points of the lens 4 close to the low-beam light source 1; a concentrator is arranged between each of the high-beam light sources 1 and the lens 4, and each of the concentrators can converge the light generated by the high-beam light source 1 to the high-beam lens part 42 of the lens.

[0045] When the small opening module provided in the above embodiment is working, the light generated by the low beam light source 2 is reflected by the reflective surface of the reflector 3 to the low beam lens portion 41 of the lens 4, and then refracted by the low beam lens portion 41 to form the low beam; the light generated by the high beam light source 1 is collected by the concentrator and projected to the high beam lens portion 42, and then projected by the high beam lens portion 42 to generate the high beam. The light energy utilization rate of the light collected by the concentrator is higher, the same light energy can produce greater brightness, and the lighting effect is better. In addition, the use of the concentrator can make the light beam more concentrated, thereby reducing the openings of the upper and lower lenses, which is more conducive to the miniaturization of the module.

[0046] In another relatively optimized embodiment of the present invention, Figure 3 and Figure 4 As shown, it includes a high-beam light source 1, a low-beam light source 2, a lens 4 and a reflector 3, wherein the low-beam light source 2 is placed at the focus of the reflector 3, and the reflector 3 and the low-beam light source 2 are placed above the high-beam light source 1, and a shielding plate 8 is provided between the high-beam light source 1 and the low-beam light source 2 to prevent the high-beam light source 1 and the low-beam light source 2 from affecting each other; the high-beam light source 1 is an LED lamp, and there are 3-7 LED lamps, and the multiple LED lamps are dispersedly arranged on the high-beam circuit board, and the high-beam circuit board And it is installed on the radiator 7; a lens 4 is arranged on one side of the high-beam light source 1 and the low-beam light source 2, the upper part of the lens 4 is a low-beam lens part 41, which is shaped like a convex lens, and the low-beam lens part 41 extends downward to form a high-beam lens part 42; a visor 5 is arranged at one of the two focal points of the lens 4 close to the low-beam light source 1; a Fresnel lens is arranged between the high-beam light source 1 and the lens 4, and the Fresnel lens can project the light generated by the high-beam light source 1 to the high-beam lens part 42 of the lens.

[0047] When the small opening module provided in the above embodiment is working, the light generated by the low beam light source 2 is reflected by the reflective surface of the reflector 3 to the low beam lens portion 41 of the lens 4, and then refracted by the low beam lens portion 41 to form a low beam; the light generated by the high beam light source 1 passes through the Fresnel lens and projects the light beam to the high beam lens portion 42, and then projects through the high beam lens portion 42 to generate a high beam. Passing through the Fresnel lens can make the light beam more uniform and the lighting effect better. Using the Fresnel lens can make the light beam more concentrated, thereby reducing the openings of the upper and lower lenses, which is more conducive to the miniaturization of the module. At the same time, using the Fresnel lens can reduce the production cost of the module.

[0048] The Fresnel lens used in the present invention is any Fresnel lens available on the market.

[0049] The small opening module provided by some embodiments of the present invention adopts the optical conversion element 6 and the high beam light source 1 to cooperate with each other, and the light generated by the high beam light source 1 is projected to the lens 4 through the optical conversion element 6, so that the light can be more concentrated, the upper and lower openings of the lens 4 can be reduced, and it is more conducive to the miniaturization of the module; at the same time, it can also improve the utilization efficiency of light, and can produce better lighting effects with the same light energy, thereby improving the market competitiveness of the module. The small opening module of the present invention forms a low beam through the low beam light source 2, the reflector 3, the shading plate 5 and the low beam lens part 41, and forms a high beam through the high beam light source 1 and the optical conversion element 6. By adopting the design of different high and low beam components, the disadvantage that a single reflective surface is difficult to take into account the high and low beam light types is overcome, and the high beam part and the low beam part can be reasonably designed respectively, so as to improve the performance of the module, and the optimal light type of the high and low beam can be achieved without affecting each other. The present invention does not require the electromagnetic valve to control the shading plate 5, and the structure of the electromagnetic valve is omitted, which can effectively reduce noise, increase the working reliability of the module and the installation accuracy of the shading plate 5.
