Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of lighting lamps, in particular to a combined running light with middle, far and near lighting functions. BACKGROUND

[0002] The running light is one of the important components of modern vehicles, which is not only used to improve the safety of night driving, but also to improve the overall aesthetics of the vehicle. With the continuous development of the automobile industry and the progress of technology, the market requirements for running lights are also constantly improving, especially the requirements for their functionality and reliability are more stringent.

[0003] The existing running light generally uses a combination of spotlight and flat light or floodlight. Although this combination can make the spotlight very far, it can achieve an effect of more than 1000 meters of 1ULX illumination distance, but the illumination width of the ordinary 100-200 meters of middle and far distance is very narrow, and the driver cannot see clearly in this range. Moreover, the light shape of flat light or floodlight is basically symmetrical up and down, about half of the light is hit above the horizontal direction, which actually does not play a role in road lighting, and there is a serious waste. CONTENT OF THE UTILITY MODEL

[0004] The present application provides a combined running light with middle, far and near lighting functions to solve the problem that the current running light is difficult to illuminate middle and far distances and near distances, and part of the light is difficult to play a role in road lighting.

[0005] A combined running light with middle, far and near lighting functions, comprising:

[0006] A rear shell with an internal cavity and a front opening;

[0007] A light-transmitting front cover arranged in the front opening and sealed with the rear shell;

[0008] A lamp assembly arranged in the rear shell, the lamp assembly can illuminate middle and far light and near light towards the light-transmitting front cover, and the illumination range of both is below the horizontal direction.

[0009] By adopting the above technical scheme, the lamp assembly can illuminate middle and far light and near light towards the light-transmitting front cover, and the illumination range of both is below the horizontal direction, which ensures that the light is mainly projected on the road surface in middle and far distances and near distances, effectively improves the utilization rate of light, avoids the waste caused by the upward scattering of light, and thus enhances the actual effect of the running light in road lighting. The rear shell has an internal cavity and a front opening, and the light-transmitting front cover is sealed with the rear shell to provide a closed working environment for the lamp assembly, which protects the lamp assembly from the interference of external dust, moisture and other factors, ensures its normal work and prolongs the service life.

[0010] In one of the embodiments, the lamp assembly comprises a lamp plate, a first light reflection part and a second light reflection part, the first light reflection part and the second light reflection part are arranged on the lamp plate, the first light reflection part is located above the second light reflection part, the first light reflection part can irradiate medium-high light towards the transparent front cover, and the second light reflection part can irradiate low light towards the transparent front cover.

[0011] By adopting the above technical solution, the first light reflection part and the second light reflection part in the lamp assembly are arranged on the lamp plate, and the first light reflection part is located above the second light reflection part. The medium-high light and low light are respectively realized by this layout. This design can make use of the characteristics of different light reflection parts to keep the light angle below the horizontal direction to effectively irradiate the road surface when switching between high and low light. This not only meets the lighting needs of vehicles in different driving scenarios (such as medium-high light for high-speed driving and low light for urban driving), but also improves the safety and comfort of driving.

[0012] In one of the embodiments, the first light reflection part comprises a plurality of first lamp beads and a plurality of first light reflection cups corresponding to the first lamp beads one by one, the width of the first light reflection cup is smaller than the width of the rear shell, the light irradiation range of the first light reflection part in the horizontal direction is (-12, 12) degrees, and the light irradiation range in the vertical direction is (0, -3) degrees.

[0013] By adopting the above technical solution, the width of the first light reflection cup is small, which can obtain a better floodlight effect. The first lamp bead irradiates towards the transparent front cover through the first light reflection cup, so that the light irradiation range in the horizontal direction is (-12, 12) degrees, and the light irradiation range in the vertical direction is (0, -3) degrees. The irradiation angle of the medium-high light can be accurately controlled to concentrate on the road surface below the front of the vehicle.

[0014] In one of the embodiments, the second light reflection part comprises a plurality of second lamp beads and a plurality of second light reflection cups corresponding to the second lamp beads one by one, the width of the second light reflection cup is smaller than the width of the rear shell, the length of each second light reflection cup is greater than the length of each first light reflection cup, the light irradiation range of the second light reflection part in the horizontal direction is (35, -35) degrees, and the light irradiation range in the vertical direction is (0, -10) degrees.

[0015] By adopting the above technical solution, the width of the second light reflection cup is smaller than the width of the rear shell and the length is greater than the length of the first light reflection cup. The second light reflection cup has a better floodlight effect, so that the low light has a wider light irradiation range (35, -35) degrees in the horizontal direction and (0, -10) degrees in the vertical direction. This ensures that the driver can clearly see the road surface near the vehicle on both sides and in front of the vehicle, including the road edge, pedestrians, obstacles, etc., when the vehicle is driving at low speed (such as urban roads), thereby improving the safety of driving.

[0016] In one of the embodiments, the lamp assembly further comprises a third light reflection part, which is arranged on the lamp panel and between the first light reflection part and the second light reflection part, and is capable of irradiating high beam towards the light-transmitting front cover. The third light reflection part comprises a plurality of third lamp beads and a plurality of third light reflection cups corresponding to the third lamp beads one by one. The width of the third light reflection cup is greater than the width of the first light reflection cup.

[0017] By adopting the above technical solution, the third light reflection part in the lamp assembly is located between the first light reflection part and the second light reflection part, and is used for irradiating high beam. The width of the third light reflection cup is greater than the width of the first light reflection cup, which makes the light of the third lamp bead more concentrated, and improves the condensing effect. For example, in some special road conditions (such as mountainous roads or roads with wide field of view), the third light reflection part can provide additional long-distance illumination, help the driver better observe the road conditions in the distance, and further improve the functionality and adaptability of the driving lamp.

[0018] In one of the embodiments, the combined driving lamp with medium-long-short illumination function further comprises a bracket, which is fixed with the rear shell and can be fixed with the frame to be fixed.

[0019] By adopting the above technical solution, stable support can be provided for the driving lamp, and the driving lamp can be firmly installed on the vehicle or other equipment. The bracket can provide appropriate fixing mode in different installation environments (such as different types of cars), thereby enhancing the universality and installation convenience of the driving lamp.

[0020] In one of the embodiments, the combined driving lamp with medium-long-short illumination function further comprises a buffer, which is arranged between the bracket and the frame to be fixed.

[0021] By adopting the above technical solution, the buffer can play a role of buffering and shock absorption. During the driving of the vehicle, vibration will be generated due to the bumping of the road surface. The buffer can reduce the influence of the vibration on the driving lamp and its connecting parts, prevent the driving lamp from loosening, damaging or affecting the illumination angle due to long-term vibration, and prevent the bracket from damaging the car.

[0022] In one of the embodiments, the front end opening is further provided with a lens cover, which is arranged on the lamp assembly and between the rear shell and the light-transmitting front cover. The light-transmitting front cover is provided with a plurality of buckles, which extend towards the rear shell and can be fixed with the rear shell.

[0023] By adopting the technical scheme, the lens arranged at the front opening is located between the rear shell and the light-transmitting front cover, and the lens can further focus, diffuse or homogenize the light emitted by the lamp assembly, thereby optimizing the lighting effect. The buckle of the light-transmitting front cover extends towards the rear shell and can be fixed with the rear shell. This buckle type fixing method is convenient for installation and disassembly, and can ensure the sealing performance between the light-transmitting front cover and the rear shell, preventing moisture and dust from entering the accommodation space and ensuring the stability of the internal environment of the running light.

[0024] In one of the embodiments, the running light further comprises a frame arranged between the rear shell and the light-transmitting front cover and fixed with the rear shell, and the lens is arranged between the frame and the rear shell, and a sealing element is further arranged between the rear shell and the lens.

[0025] By adopting the technical scheme, the frame is arranged between the rear shell and the light-transmitting front cover and fixed with the rear shell, and is used for fixing the lens, so that the position of the lens in the running light is more stable. The sealing element between the frame and the lens can further enhance the sealing effect, preventing external factors such as water vapor, dust, etc. from entering the interior of the running light and adversely affecting the lamp assembly. This multi-layer sealing and fixed structure ensures the reliability and durability of the running light, so that it can work normally under various complex environmental conditions.

[0026] In one of the embodiments, the cable is electrically connected with the lamp plate by penetrating the rear shell.

[0027] By adopting the technical scheme, the cable can power the lamp plate, and then the light-reflecting part can emit light of different distances, thereby having a good field of view in different scenes.

[0028] In summary, the present application at least includes the following beneficial effects:

[0029] 1. The lamp assembly can irradiate medium and far light and near light towards the light-transmitting front cover, and the light irradiation ranges of the two are both below the horizontal direction, which ensures that the light is mainly projected on the road surface at medium and far distances and near distances, effectively improves the utilization rate of light, avoids the waste caused by upward scattering of light, and thereby enhances the actual effect of the running light in road lighting. The hollow interior of the rear shell and the open front end, and the sealed arrangement of the light-transmitting front cover provide a closed working environment for the lamp assembly, protect the lamp assembly from interference of external dust, moisture and other factors, and ensure normal operation and prolong service life.

[0030] 2. The first light-reflecting cup has a small width, and a good floodlight effect can be obtained. The first lamp bead irradiates towards the light-transmitting front cover through the first light-reflecting cup, so that the light irradiation range in the horizontal direction is (-12, 12) degrees, and the vertical direction is (0, -3) degrees. The irradiation angle of the medium and far light can be accurately controlled, so that it is concentrated on the road surface below the front of the vehicle.

[0031] 3、Second reflector cup width is less than the width of the rear shell and the length is greater than the first reflector cup length, the second reflector cup has better floodlight effect, so that the low beam has wider light range in horizontal direction (35, -35) degree, vertical direction is (0, -10) degree, ensure that the driver can clearly see the road surface condition of both sides and front of the vehicle at low speed (such as urban road), including road edge, pedestrian, obstacle, etc., improve the driving safety.

DETAILED DESCRIPTION

[0036] The following will be combined with the Figs. 1-3 The combined driving light with middle, far and near lighting function provided by the application is further described in detail.

[0037] Embodiment 1

[0038] Please refer to Figs. 1-3 The combined driving light with middle, far and near lighting function 1 provided by the embodiment of the application includes rear shell 11, light transmission front cover 12 and lamp assembly 13.

[0039] As Figs. 1-2As shown, the rear shell 11 is hollow inside and includes a front end opening 111; the light-transmitting front cover 12 is arranged at the front end opening 111 and is sealingly arranged with the rear shell 11. Specifically, the rear shell 11 is made of a metal material and has high heat resistance and impact resistance. The rear shell 11 can have a circular or square shape. The light-transmitting front cover 12 is made of a polycarbonate material with high transparency and has good light transmittance and wear resistance. The light-transmitting front cover 12 is adapted to the shape of the rear shell 11 and can cover the rear shell 11. The edges of the light-transmitting front cover 12 are provided with a plurality of buckles 121, which extend towards the rear shell 11 and can be fixed with the outer wall surface of the rear shell 11, thereby ensuring the stability of the entire structure.

[0040] The lamp assembly 13 is arranged in the rear shell 11 and can emit medium and far light and near light towards the light-transmitting front cover 12, and the light ranges are all below the horizontal direction, thereby improving the utilization rate of light. Specifically, the lamp assembly 13 includes a lamp plate 131, a first light reflection part 132, and a second light reflection part 133. The lamp plate 131 is made of an aluminum alloy material and has good heat dissipation performance. A cable passes through the rear shell 11 and is electrically connected with the lamp plate 131. The gap between the cable and the rear shell 11 is sealed to prevent moisture from penetrating into the rear shell 11. The first light reflection part 132 and the second light reflection part 133 are both arranged on the lamp plate 131, and the first light reflection part 132 is located above the second light reflection part 133. The first light reflection part 132 can emit medium and far light, and the second light reflection part 133 can emit near light. This design enables the same lamp to simultaneously realize the emission of medium and far light and near light, and the running light can be applied to different scenes.

[0041] The first light reflection part 132 includes a plurality of first lamp beads 1321 and a plurality of first light reflection cups 1322 corresponding to the first lamp beads 1321. In this embodiment, the first lamp beads 1321 can be high-power lamp beads with three cores and are arranged at intervals. The width of the first light reflection cup 1322 is less than the width of the rear shell 11. The width direction is the direction in which the lamp assembly 13 emits light towards the light-transmitting front cover 12. In this way, more light can be directly scattered without passing through the light reflection cup. After the light scattered by the light reflection cup overlaps, a good floodlight effect can be obtained. The light range of the first light reflection part 132 in the horizontal direction is (-12, 12) degrees, and the light range in the vertical direction is (0, -3) degrees, thereby meeting the illumination brightness and width of about 100-300 meters. This design enables the medium and far light to be more accurately irradiated onto the road, thereby avoiding the safety hazards caused by the upward diffusion of light.

[0042] The second light-reflecting part 133 comprises a plurality of second lamp beads 1331 and a plurality of second light-reflecting cups 1332 corresponding to the second lamp beads 1331. In the embodiment, the second lamp beads 1331 are 6-core super-power lamp beads and are arranged at intervals, and the second light-reflecting cups 1332 are large-cup-opening wide-angle light-reflecting cups. The length of each second light-reflecting cup 1332 is greater than the length of each first light-reflecting cup 1322, and the length direction is the horizontal direction when the lamp assembly 13 is irradiated, which helps to expand the illumination range of the low beam. The second light-reflecting cup 1332 is provided with a plurality of reflecting parts arranged in the horizontal direction and the vertical direction, which increases the number of light refraction and makes the low beam more evenly distributed on the road surface. The light illumination range of the second light-reflecting part 133 in the horizontal direction is (35, -35) degrees, and the light illumination range in the vertical direction is (0, -10) degrees. Such design makes the low beam mostly irradiate to the ground and the two sides of the ground, and good near-field illumination effect of 10-100 meters can be obtained.

[0043] In addition, the lamp assembly 13 further comprises a third light-reflecting part 134, which is arranged on the lamp panel 131 and located between the first light-reflecting part 132 and the second light-reflecting part 133. The third light-reflecting part 134 can irradiate high beam and is suitable for long-time driving on the highway. The third light-reflecting part 134 comprises a plurality of third lamp beads 1341 and a plurality of third light-reflecting cups 1342 corresponding to the third lamp beads 1341. The width of the third light-reflecting cup 1342 is greater than the width of the first light-reflecting cup 1322 and the second light-reflecting cup 1332, which helps to increase the illumination distance and the condensing effect of the high beam. The third light-reflecting cup 1342 is designed like a parabolic surface, so that the light can be better focused, and the penetration of the high beam is improved. In the embodiment, the third lamp beads 1341 are single-core high-density small-size high-power lamp beads, and the third light-reflecting cups 1342 are deep-cup-opening reflecting cups, which are designed to super-condense light and can achieve an illumination distance of 1LUX 1000 meters.

[0044] The combined driving lamp 1 with medium and long-range lighting function further comprises a bracket 14, which is fixed with the rear shell 11 and can be fixed with the frame to be fixed. In the embodiment, the bracket 14 is U-shaped and arranged below the rear shell 11 in the vertical direction. The two ends of the bracket 14 extend to the two ends of the rear shell 11 in the horizontal direction and are fixed with the rear shell 11. The middle part of the bracket 14 can be fixed with the frame to be fixed. Specifically, the bracket 14 is made of high-strength steel material and has good rigidity and anti-vibration ability. The two ends of the bracket 14 are connected with the rear shell 11 by welding or screw fixing, which ensures the stability of the structure.

[0045] The lower end of the support 14 is provided with a buffer 15 made of rubber, which can absorb vibration during driving and prevent scratching the vehicle body. The middle part of the support 14 is provided with a mounting hole, by which the support 14 and the buffer 15 can be fixed to the frame or bumper of the vehicle by bolts or other fasteners.

[0046] As shown in Fig. 3 The running light is additionally provided with a lens 16 at the front end opening 111. The lens 16 covers the lamp assembly 13 and is located between the rear shell 11 and the light-transmitting front cover 12. The lens 16 can further optimize the propagation path of light and make it more concentrated in the required area. The surface of the lens 16 is specially treated to have anti-glare and anti-fog functions, ensuring good light transmission performance in various weather conditions.

[0047] The combined running light 1 with the middle and far and near lighting functions further includes a frame 17. The frame 17 is located between the rear shell 11 and the light-transmitting front cover 12 and is fixed to the rear shell 11, and the lens 16 is located between the frame 17 and the rear shell 11. Specifically, the frame 17 is made of plastic material and has the characteristics of light weight and durability. The frame 17 is provided with a groove around the periphery, which facilitates the embedding and fixing with the rear shell 11. The lens 16 is located between the frame 17 and the rear shell 11, and the outer edge of the lens 16 is tightly attached to the frame 17 to prevent water from entering the inside. A rubber sealing element is further provided between the rear shell 11 and the lens 16 to further enhance the sealing performance and prevent dust and water vapor from entering.

[0048] The implementation principle of the embodiment is that by reasonably arranging the first, second and third reflecting parts 132, 133 and 134, the middle and far light, the near light and the far light are simultaneously irradiated in the same lamp, and when the middle and far light and the near light are irradiated, the horizontal irradiation range is wide and the vertical irradiation is realized below the horizontal line, so that the light can be fully irradiated on the road surface, improving the light utilization rate and the lighting effect.

[0049] By additionally providing the support 14 and the lens 16, the stability and the shock resistance of the structure are enhanced, and the distribution of light is further optimized, improving the overall lighting effect.

[0050] The above are the preferred embodiments of the present application, which do not limit the protection scope of the present application, therefore: any equivalent changes made on the structure, shape and principle of the present application should be covered within the protection scope of the present application.
