Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of long strip lamps, in particular to a low wind resistance long strip lamp and a car. BACKGROUND

[0002] Lighting equipment is an indispensable part of modern vehicles, especially when driving at night, which can significantly improve driving safety and comfort. In recent years, with the continuous progress of car design, the design of lamps has gradually developed towards aesthetics, energy saving and functionality. As a common form of car light, long strip lamps not only meet the basic lighting needs, but also undertake the task of improving the aesthetic appearance of vehicles. However, the performance of traditional long strip lamps in terms of wind resistance is not ideal, which not only affects the aerodynamic performance of the whole vehicle, but also increases energy consumption.

[0003] The current market products are relatively simple in appearance, and the front of the lamp is simply designed as a whole plane, without considering the problem of wind resistance in actual scene application. CONTENT OF THE INVENTION

[0004] The present application provides a low wind resistance long strip lamp to solve the problem that the current long strip lamp is difficult to reduce wind resistance.

[0005] A low wind resistance long strip lamp, comprising:

[0006] a strip-shaped shell, which is hollow inside and includes a front end opening;

[0007] a lamp assembly, which is fixed in the strip-shaped shell and can project light to the front end opening; and

[0008] a light-transmitting front cover, which is provided at the front end opening and fixed with the strip-shaped shell, the light-transmitting front cover includes a windward surface, and the windward surface is arranged to extend in a direction in which wind resistance decreases from one end side.

[0009] By adopting the above technical solution, the windward surface of the light-transmitting front cover extends in a direction in which wind resistance decreases from one end side, which lays a foundation for reducing wind resistance as a whole, can effectively reduce air resistance, has important significance for application in high-speed moving objects such as cars, can reduce energy consumption, and improve driving stability and speed; in addition, the strip-shaped shell with hollow inside and front end opening provides installation space for the lamp assembly, and ensures the light projection channel.

[0010] In one embodiment, the windward surface is curved to form an upper windward surface and a lower windward surface, the side of the upper windward surface away from the lower windward surface extends in a direction close to the strip-shaped shell, and the side of the lower windward surface away from the upper windward surface extends in a direction close to the strip-shaped shell.

[0011] By adopting the technical scheme, the windward surface is curved to form an upper windward surface and a lower windward surface, and the two sides extend towards the direction close to the strip-shaped shell. This design can guide the airflow to flow more smoothly through the lamp body surface, reduce the stagnation and disorder of the airflow in front of the lamp body, and further reduce the wind resistance. Meanwhile, the curved shape can also increase the structural strength of the light-transmitting front cover, so that the light-transmitting front cover is more stable when bearing wind pressure and is not easy to deform, thereby prolonging the service life of the long strip lamp.

[0012] In one of the embodiments, the width of the upper windward surface is greater than the width of the lower windward surface.

[0013] By adopting the technical scheme, this asymmetric design can better adapt to the airflow distribution in actual use. During the driving of the vehicle, the airflow speed and pressure distribution above may be different from that below. Through this differentiated design, the airflow flow can be more effectively optimized, the overall wind resistance can be reduced, and the vehicle aerodynamic performance can be balanced, thereby improving the driving stability and maneuverability.

[0014] In one of the embodiments, the angle between the upper windward surface and the vertical direction is between 5 degrees and 15 degrees.

[0015] By adopting the technical scheme, the angle between the upper windward surface and the vertical direction is limited to a specific range, so that the flow trajectory and separation point of the airflow on the upper windward surface can be accurately controlled, the airflow can flow more smoothly through the lamp body, the vortex can be reduced, and the purpose of reducing wind resistance can be achieved. Through a large number of experiments and simulation calculations, this angle range can ensure good low wind resistance effect under different driving speeds and environmental conditions, thereby improving the adaptability and reliability of the long strip lamp.

[0016] In one of the embodiments, the angle between the lower windward surface and the vertical direction is between 25 degrees and 35 degrees.

[0017] By adopting the technical scheme, similar to the angle range of the upper windward surface, by reasonably setting this angle, the airflow below can be better separated from the lamp body surface, the airflow can be prevented from accumulating below the lamp body, the wind resistance can be further reduced, and the accumulation of dust and debris below the lamp body can be reduced, thereby maintaining the cleanliness and good heat dissipation performance of the lamp body.

[0018] In one of the embodiments, the relative two ends of the strip-shaped shell are respectively provided with fixing members for connecting with the vehicle body.

[0019] By adopting the technical scheme, this mounting method can ensure that the long strip lamp will not be loosened or displaced during the driving of the vehicle due to vibration and other factors, thereby ensuring the stability and safety of the lighting. Meanwhile, the fixed ends facilitate installation and disassembly, and facilitate maintenance and replacement in the later period.

[0020] In one of the embodiments, the strip-shaped shell is an integrally formed structure.

[0021] By adopting the above technical solution, the integrally formed strip-shaped shell has the advantages of compact structure, high strength, good sealing performance, etc. The connection gaps between parts can be reduced, and dust, moisture, etc. can be prevented from entering the inside of the shell, thereby protecting the lamp assembly from the influence of the external environment, improving the reliability and durability of the long strip lamp. In addition, the integrally formed structure can simplify the production process, reduce production costs, and improve production efficiency.

[0022] In one of the embodiments, the lamp assembly includes a lamp panel and a light reflecting member, both of which extend along the length direction of the strip-shaped shell, and the light emitted by the lamp panel is projected to the light-transmitting front cover through the light reflecting member.

[0023] By adopting the above technical solution, this design can make the light more fully utilized and uniformly distributed inside the long strip lamp. The light reflecting member can effectively reflect and project the light emitted by the lamp panel to the light-transmitting front cover, improving the utilization rate of light and the lighting effect, and ensuring that the long strip lamp can provide uniform and bright illumination in all directions, meeting different use requirements.

[0024] In one of the embodiments, the lamp panel includes two groups of upper and lower lamp panels, and the light reflecting member is V-shaped, including a first reflecting part and a second reflecting part, and the first reflecting part and the second reflecting part can reflect the light emitted by the two groups of upper and lower lamp panels, respectively.

[0025] By adopting the above technical solution, this design can further optimize the distribution and projection angle of light, and realize more precise lighting control. For example, in the automobile headlamp, this design can realize the function switching of low beam and high beam, or provide different lighting modes in different driving scenes, improving the flexibility and practicality of lighting, and also helping to reduce the glare effect on other road users, improving the driving safety.

[0026] The embodiments of the present application also provide an automobile, including a roof and a low-drag long strip lamp, and the low-drag long strip lamp is fixed to the roof.

[0027] By adopting the above technical solution, the low-drag long strip lamp is fixed to the roof of the automobile, which not only provides lighting function for the automobile, but also reduces air resistance during driving due to its low-drag characteristics, thereby reducing fuel consumption and improving fuel economy.

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

[0029] 1. The windward surface of the light-transmitting front cover extends from one end side to the direction of reduced wind resistance, which lays the foundation for reducing wind resistance as a whole, effectively reducing air resistance, and has important significance for application on high-speed moving objects such as cars, which can reduce energy consumption and improve driving stability and speed; in addition, by setting the internally hollow and front-end open strip-shaped shell, an installation space is provided for the lamp assembly, ensuring the projection channel of the light.

[0030] 2. This asymmetric design can better adapt to the airflow distribution in actual use. The airflow speed and pressure distribution above may be different from that below during the driving of the car. Through this differentiated design, the airflow can be more effectively optimized, the overall wind resistance can be reduced, and the vehicle's aerodynamic performance can be balanced, improving driving stability and maneuverability.

[0031] 3. This installation method can ensure that the long strip lamp does not loosen or shift during vehicle driving due to vibration and other factors, ensuring the stability and safety of lighting. At the same time, the fixed method at both ends not only adjusts the angle of the long strip lamp, but also facilitates installation and removal, facilitating later maintenance and replacement.

DETAILED DESCRIPTION

[0036] The following will be combined with the Figs. 1-3 The low wind resistance long strip lamp provided by the present application is further described in detail.

[0037] Embodiment 1

[0038] Please refer to Figs. 1-3 The low wind resistance long strip lamp 1 provided by the present application includes a strip-shaped shell 11, a lamp assembly 12, and a light-transmitting front cover 13.

[0039] As Figs. 1-2 shown in the drawings, the strip-shaped shell 11 is hollow inside and has a front end opening 111. Specifically, the strip-shaped shell 11 is integrally formed and can be made of aluminum material, which not only increases the overall strength, but also simplifies the manufacturing process and reduces the production cost. The strip-shaped shell 11 is provided with fixing members 14 connected to the vehicle body at opposite ends along the length direction of the strip-shaped shell 11. These fixing members 14 can be fixed on the vehicle body by bolts or other fasteners to ensure that the lamp is stably and reliably installed on the vehicle. In this embodiment, the fixing member 14 can be an "L"-shaped fixing seat, one end of which is bolted to the strip-shaped shell 11, and the other end is bolted to the roof.

[0040] As Fig. 3 shown in the drawings, the lamp assembly 12 is fixed in the shell and projects light to the front end opening 111. The lamp assembly 12 includes a lamp panel 121 and a reflector 122, which extend along the length direction of the strip-shaped shell 11. The light emitted by the lamp panel 121 is projected to the light-transmitting front cover 13 through the reflector 122. Specifically, the lamp panel 121 includes a plurality of LED lamp beads, which have the advantages of high efficiency and energy saving. The back of the lamp panel 121 can be coated with a layer of heat-conducting silicone grease to improve the heat conduction efficiency and ensure that the lamp panel 121 maintains a relatively low temperature in a long-time working state. The lamp panel 121 can be a flexible circuit board, which has good flexibility and ductility. The flexible circuit board can be bent into the required shape to meet the installation requirements of different spaces. The reflector 122 can be a metal plating or a plastic material, which has good reflection performance and can maximize the concentration of light to the front to improve the lighting effect. The cable 15 is electrically connected to the lamp panel 121 through the rear end of the strip-shaped shell.

[0041] To further optimize the light distribution, the lamp panel 121 can be divided into two groups, and the reflector 122 is V-shaped and has a large-diameter end away from the light-transmitting front cover 13. The reflector 122 can include a first reflection part 123 and a second reflection part 124 along the height direction. The first reflection part 123 and the second reflection part 124 are both concave away from the light-transmitting front cover 13. The first reflection part 123 and the second reflection part 124 can reflect the light emitted by the upper and lower lamp panels 121, respectively, which can achieve more uniform light distribution and avoid the situation of local over-brightness or over-darkness.

[0042] The light-transmitting front cover 13 is arranged at the front end opening 111 and fixed with the strip-shaped shell 11, and the light-transmitting front cover 13 comprises a windward surface 131 extending from one end side to a direction in which the wind resistance is reduced. The light-transmitting front cover 13 can be made of polycarbonate material, which has excellent light transmission and weather resistance. The windward surface 131 of the light-transmitting front cover 13 is designed as a curved surface, which can effectively guide the airflow and reduce vortex generation. The windward surface 131 can have only one surface or be divided into multiple surfaces, which can all play a role in reducing wind resistance. In the embodiment, the windward surface 131 is curved to form an upper windward surface 132 and a lower windward surface 133. The width ratio and inclination angle of the upper windward surface 132 and the lower windward surface 133 can be optimized according to the specific needs of different vehicle models. The width of the upper windward surface 132 is greater than that of the lower windward surface 133, the included angle between the upper windward surface 132 and the vertical direction is between 5 degrees and 15 degrees, and the included angle between the lower windward surface 133 and the vertical direction is between 25 degrees and 35 degrees. Such a design can maximize the reduction of wind resistance while ensuring the lighting effect.

[0043] In addition, a sealing gasket 134 is additionally arranged at the edge of the light-transmitting front cover 13, which can effectively prevent water vapor from entering the lamp interior through the gap between the light-transmitting front cover 13 and the strip-shaped shell 11, and improve the waterproof performance. The sealing gasket 134 can be made of rubber or silicone material, which has good elasticity and aging resistance. The connection between the light-transmitting front cover 13 and the strip-shaped shell 11 can be fixed by buckles or screws, which is convenient for disassembly and maintenance, and can also ensure the firmness of the connection.

[0044] The embodiment of the application also includes a car, which comprises a roof and a low wind resistance long strip lamp 1, and the low wind resistance long strip lamp 1 is installed on the roof by a fixing member 14 and can adjust the illumination angle of the low wind resistance long strip lamp 1.

[0045] The implementation principle of the embodiment is that by optimizing the overall shape of the lamp and the design of the windward surface 131 of the light-transmitting front cover 13, effective airflow guidance is achieved, vortex generation is reduced, and wind resistance is significantly reduced. At the same time, the integrated strip-shaped shell 11 and the efficient lamp assembly 12 design make the entire lamp structure compact and light in weight, which is easy to install and maintain. This low wind resistance long strip lamp 1 not only improves the fuel economy and driving experience of the car, but also prolongs the service life of the lamp to a certain extent, which has high practical value.

[0046] The above are preferred embodiments of the application, which do not limit the protection scope of the application, therefore: any equivalent changes made on the basis of the structure, shape and principle of the application should be covered within the protection scope of the application.
