Description

Technical Field

[0001] The utility model relates to the technical field of vehicle lamp lighting, in particular to a high beam lens module and a vehicle lamp. Background Art

[0002] Headlights are used in the front area of ​​a vehicle to produce position lights, side lights, indicator lights or daytime running lights. Headlights can be integrated in headlamps or designed as separate lights, which preferably work according to the reflection principle, i.e. they have at least one reflector that reflects the light emitted by the light source so that the light beam emitted by the lamp produces the desired light distribution on the road and / or on the road in front of the vehicle in the light emission direction of the light. In order to reduce the production costs of vehicle lights, combined vehicle lighting that provides different signal and lighting functions in one lighting device is constantly being improved in the automotive industry.

[0003] There is a lighting device for a motor vehicle, which has at least two light sources, the first light source is designed for high beam and low beam, and the other light source is designed to form a daytime running light or a signal light. A typical representative is German patent DE102010056312B4. The lighting device also includes a reflector to combine the light beams from the two sources and produce two different light beams. This effect is achieved by the reflector having a specific reflective surface composed of two different structures, the first structure is suitable for the first light source, and the other structure is suitable for the second light source. In order to achieve the best effect, the structures on the specific reflective surface are arranged in a checkerboard. A disadvantage of this solution is that the light source (in this case, the LED) is located outside the focus of the reflector, which means that the light beam from the other light source for signal lighting does not have enough width, and on the contrary, too high a light intensity must be met to meet the legal requirements for daytime running lights and parking lights.

[0004] For example, patent DE19916845B4 shows a motor vehicle lamp having two separate light sources, each of which is used to generate a specific light distribution. Each of the two light sources is assigned a separate reflector, and the light reflected by the reflector generates a different light distribution. The two reflectors are of different sizes, with the smaller first reflector being arranged inside the larger second reflector. When the lamp is viewed against the light emission direction, the light sources are arranged one after the other in the reflector arrangement. Such a lamp has the disadvantage that the first reflector partially obscures the reflective surface of the second reflector. Therefore, it is only possible to achieve a light distribution with a relatively low luminous intensity, such as a flash light or a position light, with a relatively small first reflector and a larger but partially obscured second reflector. In order to achieve, for example, a bright daytime running light, the effective reflective surface of the first and second reflectors of the known lamp is too small. In addition, when the lamp is viewed in a direction opposite to the light emission direction, the light beams used to achieve the two light distributions are offset from each other when they are emitted from the lamp, which has a disruptive effect.

[0005] In order to solve the problem of auxiliary light sources being used as daytime running lights, position lights, ambient lights, turn signals, fog lights, auxiliary low beams or auxiliary high beams in the prior art, one way is to add a dedicated reflective bowl for reflecting the auxiliary light source, and another way is to integrate the auxiliary light source and the high beam light source in one reflective bowl, but multiple reflective surfaces need to be set. Utility Model Content

[0006] (I) Technical problems solved: In view of the deficiencies of the prior art, the present invention provides a high-beam lens module and a headlight, which integrate an auxiliary light source and a high-beam LED light source in a high-beam reflective bowl, thereby solving the problem of needing to design multiple matching reflective surfaces in the high-beam reflective bowl.

[0007] (II) Technical solution: In order to achieve the above-mentioned purpose of not setting multiple reflective surfaces in a high beam reflective bowl, the utility model provides the following technical solution:

[0008] A high-beam lens module comprises a high-beam LED light source and an auxiliary light source arranged on a PCB board, an outer lens, and a high-beam reflective bowl semi-enclosing the high-beam LED light source and the auxiliary light source, wherein the longitudinal section of the high-beam reflective bowl in the direction of light emission from a vehicle headlight is an elliptical curve, the high-beam LED light source is located at one of the foci of the elliptical curve, and the auxiliary light source is not located at any of the foci but within the vertical projection plane of the high-beam reflective bowl, the high-beam reflective bowl has a single complete reflecting surface, and the light emitted by the high-beam LED light source is reflected by the high-beam reflective bowl and then emitted, and finally refracted by the outer lens to form a high-beam light pattern.

[0009] In a preferred embodiment of the present invention, the high-beam lens module includes a heat sink, and the heat sink is located on a side of the back of the PCB board that is away from the high-beam reflective bowl.

[0010] In a preferred embodiment of the present invention, the heat sink comprises a plurality of heat sinks, and the heat sinks are adapted to the length gradient change of the lampshade housing.

[0011] In a preferred embodiment of the utility model, the high beam reflective bowl includes a protrusion, which is used for contact between the high beam reflective bowl and the PCB board. Since the protrusion is a protruding structure, a small area contacts the PCB board, and a large area has an air gap, which is conducive to heat dissipation.

[0012] In a preferred embodiment of the present invention, the high beam reflector bowl also includes a positioning column and a screw hole. The positioning column is used to position the high beam reflector bowl on the PCB board, and the screw hole fixes the high beam reflector bowl to the PCB board by screws to prevent the high beam reflector bowl from being dislocated due to vibration and affecting the reflection of light.

[0013] In a preferred embodiment of the present invention, a sheet-shaped handle extends from the rear end of the high-beam reflector bowl in the direction of light reflection, and the handle structure is an integral injection-molded structure of the high-beam reflector bowl, which can be used for rapid installation and maintaining positioning accuracy.

[0014] In a preferred embodiment of the present invention, the outer lens is a projection lens with a small opening, and each headlight includes at least two high-beam lens modules.

[0015] In a preferred embodiment of the present invention, the auxiliary light source is an auxiliary high-beam light source, an auxiliary low-beam light source, a position light, or an ambient light.

[0016] In a preferred embodiment of the present invention, the high beam reflective bowl 200 is made of transparent silicone material.

[0017] The utility model also provides a vehicle lamp, which comprises a high beam lens module using any one of the above embodiments.

[0018] (III) Beneficial effects: Compared with the prior art, the utility model provides a high-beam lens module and a headlight, which have the following beneficial effects:

[0019] 1. The utility model adopts a projection lens with a small opening, so that the appearance size of each module unit becomes smaller, thereby having greater freedom for combination to form different overall shapes of the headlights, and the outer surface of the projection lens can be designed to be completely consistent, thereby ensuring the consistency of each unit. This consistent unit and diverse overall combination design meet the mainstream aesthetic standards;

[0020] 2. Each high-beam lens module integrates the functions of high-beam and auxiliary lights, so no additional space is needed to install auxiliary lights, saving installation space in the headlights. At the same time, different high-beam lens modules can be flexibly placed to provide multiple lighting modes in conjunction with low-beam lens modules. The headlights of this application achieve a multifunctional, space-saving and flexible design.

[0021] 3. Multiple light sources are set in a high beam reflector bowl, which is a combination of high beam LED light source and auxiliary light source. When driving with low beam on and high beam off, the auxiliary light source is turned on, and the whole headlight is visually lit, instead of the high beam light source not being on, which causes a visual void. The high beam reflector bowl has only one reflective surface, which can reflect the high beam LED light source and the auxiliary light source at the same time without affecting the high beam and low beam patterns, and has a simple structure.

[0031] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] See also Figure 1-Figure 3The high-beam lens module includes a high-beam LED light source 600 and an auxiliary light source 500, an outer lens 300, and a high-beam reflector 200 that semi-encloses the high-beam LED light source 600 and the auxiliary light source 500, and the longitudinal section of the high-beam reflector 200 in the direction of light emission from the headlight is an elliptical curve, the high-beam LED light source 600 is located at one of the foci of the elliptical curve, and the auxiliary light source 500 is not at any of the foci but within the vertical projection plane of the high-beam reflector 200, the high-beam reflector 200 has a single complete reflecting surface, the light emitted by the high-beam LED light source 600 is reflected by the high-beam reflector 200 and then emitted, and finally refracted by the outer lens 300 to form a high-beam light pattern, and the high-beam reflector 200 is an independent semi-enclosed structure, which will not cause light leakage when the light source in the high-beam reflector 200 diverges to cause light crosstalk.

[0033] The high beam lens module includes a heat sink 400 , which is located on a side of the back of the PCB board 100 away from the high beam reflector bowl 200 .

[0034] The heat sink 400 includes a plurality of heat sinks, which are adapted to the lampshade housing to change in length and gradient, so that the high-beam lens module can be better adapted to the lampshade housing, and are used to dissipate heat when the lens module is illuminated.

[0035] like Figure 2 As shown, the high beam reflector 200 includes a protrusion 210, and the protrusion 210 is used for the contact between the high beam reflector 200 and the PCB board 100. Since the protrusion 210 is a protruding structure, a small area contacts the PCB board 100, and a large area has an air gap, which is conducive to heat dissipation.

[0036] The high beam reflector 200 further includes a positioning post 800 and a screw hole 700. The positioning post is used to position the high beam reflector 200 on the PCB board 100. The screw hole 700 fixes the high beam reflector 200 on the PCB board 100 by screws to prevent the high beam reflector 200 from being dislocated due to vibration and affecting the reflection of light.

[0037] A sheet-shaped handle 220 extends from the rear end of the high-beam reflector bowl 200 in the direction of reflecting light. The handle 220 is an integrally injection-molded structure of the high-beam reflector bowl and can be used for rapid installation and maintaining positioning accuracy.

[0038] The outer lens 300 is a projection lens with a small opening, and each headlight includes at least two high-beam lens modules.

[0039] In this embodiment, the high beam reflective bowl 200 and the light-type baffle are made of light-transmitting material, preferably transparent silicone material. The advantages are that transparent silicone has high temperature resistance, is not easy to yellow after long-term light exposure, and is soft, so it can be installed at a close distance to the light source and has high light efficiency.

[0040] like Figure 3 As shown, the high beam reflector 200 can be in multiple combinations. Looking down, the high beam LED light source 600 is located at the focus of the high beam reflector 200, and the auxiliary light source 500 is located behind the high beam LED light source 600 and closer to the screw hole 700. In fact, the auxiliary light source 500 can be located at any position in the high beam reflector 200, and its position and light distribution method can be adjusted according to actual needs. However, the high beam LED light source 600 needs to be located at the focus, and the light intensity projected at the focus can be the largest. Figure 4 , the auxiliary light source is located at the opening of the high beam reflector bowl 200.

[0041] The auxiliary light source 500 can also be an auxiliary high beam, an auxiliary low beam, a position light, an ambient light, etc. The auxiliary high beam or low beam can be used to supplement the darker areas of the high beam or low beam in the prior art. The position light and the ambient light do not require the same light intensity as the low beam or high beam. Therefore, the present solution can also realize the functions of the position light and the ambient light without the need for additional space to install the auxiliary light, thus saving the installation space in the car light. At the same time, different numbers of lens modules can also be flexibly placed to provide a variety of lighting modes.

[0042] Figure 5 The light pattern formed by the projection of the auxiliary light source provided in this application, Figure 6 This is the light pattern formed by the low beam LED light source provided in this application. It can be seen that the main light energy is integrated below the 0 axis, the brightest in the middle, and gradually decreases outwards, such as Figure 7 As shown in the figure, after the auxiliary light and the low beam are superimposed, the light pattern of the auxiliary light does not affect the light pattern of the low beam. The light intensity at 50 meters and 70 meters ahead meets the requirements, and visually it is in a fully lit state without a sense of emptiness. Figure 8 It is the superimposed light pattern of low beam and high beam. Similarly, when the auxiliary light is on, it does not affect the light pattern of low beam and high beam, and also meets the requirements.

[0043] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "comprise a ..." do not exclude the existence of other identical elements in the process, method, article or device including the elements.

[0044] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
