DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments.

[0023] Referring to Figures 1-5The utility model provides a novel LED fog lamp module, which comprises an outer frame 1 fixed on a vehicle and a plurality of LED fog lamp bodies 2 arranged and installed on the outer frame 1. The outer frame 1 can provide a unified and standard mounting interface for the plurality of LED fog lamp bodies 2, realize "modularized splicing", and facilitate the vehicle manufacturer to increase or decrease the number of lamps as needed, form a through-type lamp strip, and flexibly configure the number and arrangement mode of the module. At the same time, the independence and adjustability of the single module greatly simplify the daily maintenance and replacement process. An angle fine adjustment mechanism 3 for adjusting the pitch angle of the LED fog lamp body 2 is arranged between the connection between the outer frame 1 and the LED fog lamp body 2. The angle fine adjustment mechanism 3 can solve the pain point that the irradiation angle of the traditional LED fog lamp module is not adjustable. It can directly adjust the irradiation angle deviation of the LED fog lamp module caused by the change of the vehicle load or the manufacturing tolerance, and ensure that the light type is in the best position and meets the regulations. A heat sink 21 and an LED light source substrate 22 mounted on the heat sink 21 are arranged in the LED fog lamp body 2. The heat sink 21 can quickly conduct the heat generated by the LED light source substrate 22 during operation to ensure the long service life and light output stability of the light source and prevent early light decay or failure caused by overheating. The light emitting surface of the LED light source substrate 22 is integrated with a low beam light source, a high beam light source and a turn signal light source, which can realize "one lamp with multiple functions", thereby simplifying the vehicle front wiring and structure and expanding the application scenarios. The light emitting surface of the LED light source substrate 22 is further covered with a reflector cup 24 with a light outlet facing a lens 23. The reflector cup 24 is provided with a baffle 25 for forming a light type required by regulations.

[0024] In detail, in the present embodiment, the present application integrates the low beam, high beam and turn signal light sources on the same LED light source substrate 22, realizes that a single module has multiple lighting and signaling functions, which can simplify the light layout of the vehicle front, reduce the complexity of the vehicle wiring and manufacturing cost, and achieve a leap from "single fog lamp" to "comprehensive lighting unit".

[0025] Moreover, the high beam light source integrated on the LED light source substrate 22 can provide high-intensity auxiliary lighting, effectively expand the application scenarios, make it not only serve as a fog lamp, but also provide supplemental brightness when the main headlight brightness is not enough, meet the strong demand for high beam lighting in rural roads, highways and other scenes, and realize the dual role of "fog lamp + auxiliary main lamp".

[0026] In more detail, in the present embodiment, the unique angle fine adjustment mechanism 3 can allow the pitch angle of each LED fog lamp body 2 to be adjusted after installation, which ensures that the irradiation light type of the LED fog lamp body 2 can be adjusted to the position required by regulations regardless of the change of the vehicle load or vehicle model, effectively avoids glare to oncoming vehicles, and guarantees the best illumination range and warning effect of itself.

[0027] In detail, in the embodiment, the low beam, high beam and turn signal light sources of the LED fog lamp module can be independently or combinedly turned on. For example, in bad weather, the low beam light source can be turned on as a fog lamp; in unlighted road, the low beam and high beam can be turned on to serve as an auxiliary headlamp; in turning, the turn signal light source is independently controlled to flash.

[0028] In detail, the following is the specific embodiment of the LED fog lamp module:

[0029] 1. In the city or when meeting, the low beam light source on the LED light source substrate 22 can be turned on to provide wide and short distance road lighting as a supplement to the main headlamp.

[0030] 2. In the poor lighting condition of rural road or unlighted highway, the low beam light source and high beam light source on the LED light source substrate 22 can be simultaneously turned on to work with the main headlamp to significantly expand the long distance forward vision.

[0031] 3. In the turning of the vehicle, the turn signal light source on the LED light source substrate 22 can be turned on to provide lower and more easily perceived lateral signal prompt, which is especially suitable for complex traffic environment and enhances the communication ability of the dynamic intention of the vehicle.

[0032] Further, in the embodiment, as shown in Figure 2 , Figure 3 and Figure 5 , the angle fine adjustment mechanism 3 includes a threaded column 31 penetrating the outer frame 1 and connected to the end of the LED fog lamp body 2, a elastic compression spring 32 is sleeved on the threaded column 31 and arranged between the LED fog lamp body 2 and the outer frame 1, and a anti-loose nut 33 is locked on the threaded column 31 and pressed on the LED fog lamp body 2. The technical personnel can change the compression amount of the compression spring by rotating the anti-loose nut 33, so as to adjust the LED fog lamp body 2 to be raised or lowered with the front end as the axis, which directly raises the pointing direction of the optical axis and makes the irradiation light spot return to the specified position of the regulation. This whole process does not need to be knocked with tools, and the fast on-site calibration can be realized.

[0033] Further, in the embodiment, as shown in Figure 2 , Figure 3 and Figure 5As shown, the outer frame 1 is provided with a decoding board 11 electrically connected with the LED light source substrate 22 for driving the light sources on the LED light source substrate 22 to light up in a preset mode, which can be responsible for executing complex preset lighting modes (such as sequential lighting, welcome water dynamic effect, high-low beam intelligent switching in specific scenes, etc.). It transmits the processed control signal to the driving component 26, and does not directly drive large current itself, reducing heat and interference and improving the stability of complex logic operation. The LED fog lamp body 2 is internally provided with a driving component 26 electrically connected with the LED light source substrate 22 for independently driving each light source to light up or off, which can be specially responsible for receiving instructions (such as signal instructions for controlling the car light by the car machine) and independently and accurately driving each light source (low beam, high beam, turn signal) to light up or off. This division of labor enables the basic lighting function to be guaranteed through the driving component 26 even if the decoding board 11 fails or needs to be upgraded, realizing "function degradation" safety protection and greatly improving the overall reliability of the system.

[0034] Moreover, the decoding board 11 is centrally arranged on the outer frame, and only one set of power supply and signal lines need to be connected, and then the decoding board 11 distributes the power supply and signal lines to the driving components 26 of each LED fog lamp body 2 through internal lines, which simplifies the complex wire harness from the vehicle body to the fog lamp module and reduces the difficulty and cost of vehicle wiring. When a single LED fog lamp body 2 fails, the entire lamp body module (including the driving component 26) can be replaced directly without touching the decoding board 11 on the outer frame, realizing "plug and play" type rapid maintenance with high maintenance efficiency and low cost.

[0035] Further, in the embodiment, as shown in Figure 3 The outer end of the LED fog lamp body 2 is provided with a protruding piece 28, and the front end of the pressing strip 27 abuts against the protruding piece 28 to limit the displacement of the LED fog lamp body 2. When the angle adjustment mechanism 3 drives the rear end of the lamp body to rise and fall through the elastic compression spring 32, the front end of the lamp body needs a stable fulcrum to realize pure pitching rotation. The abutment of the front end of the pressing strip 27 and the protruding piece 28 forms a certain rotation axis. Moreover, this design can ensure that the movement of the lamp body is controllable and predictable pure rotation when adjusting the anti-loose nut 33, rather than uncontrollable shaking, thereby ensuring the accuracy and repeatability of the irradiation angle adjustment.

[0036] Further, in the embodiment, as shown in Figure 3 The pressing strip 27 is provided with an arc-shaped abutting surface matched with the protruding piece 28. When adjusting the angle of the lamp body, the rear end of the lamp body is pressed down, and the front end will produce a small circular motion track around the fulcrum. The flat abutting surface will produce serious sliding friction and interference with the protruding piece 28, resulting in laborious, unsmooth and even stuck adjustment.

[0037] Further, in the embodiment, as shown inFigure 2 As shown, the outer frame 1 comprises a front and rear arranged bracket mask 12 and outer frame bracket 13, bracket mask 12 and outer frame bracket 13 on the corresponding opening for LED fog lamp body 2 assembly in which the assembly groove 14, can be each LED fog lamp body 2 provides the accurate installation path and the final positioning reference, ensure that all lamp bodies can be arranged neatly after installation, the optical center line remains consistent. The outer frame bracket 13 is provided with the outwardly protruding connecting piece 15 for its assembly to the vehicle, the lower end of the outer frame bracket 13 is provided with a reinforcing rib structure 16, so that the deformation and potential fracture risk caused by vehicle vibration, road impact and installation pre-tightening force can be effectively resisted.

[0038] Further, in the embodiment, as shown in Figure 3 As shown, the radiator 21 is inverted L type structure, LED light source substrate 22 horizontally attached to the horizontal inner side wall of the radiator 21, the horizontal part of the radiator 21 can form a "ceiling" or "mounting platform", and this platform structure can provide a shielded, protected installation position for the LED light source substrate 22 and driving assembly 26, so that it is protected from dust, water droplets or mechanical interference that may exist above. At the same time, the heat generated by the LED light source substrate 22 during operation can be directly and vertically conducted to the horizontal part of the radiator 21, and then diffused to the entire inverted L type radiator body. The connecting terminal 221 on the LED light source substrate 22 passes through the radiator 21 and is electrically connected with the driving assembly 26, and the present application is connected by "point-to-point", rather than by lengthy internal cables, which can reduce impedance and failure rate, and if the driving assembly 26 needs to be replaced, only the rear of the lamp body needs to be operated, without the need to disassemble the optical components in front, simplifying the maintenance process.

[0039] The above is only the preferred specific implementation of the present application, but the protection scope of the present application is not limited to this, any skilled person in the art within the technical range disclosed by the present application, according to the technical scheme of the present application and the utility model concept, equivalent replacement or change, should be covered within the protection scope of the present application.
