[0053] In addition to the problems mentioned in the background art, the traditional lighting module also has the following problems:
[0054] 1. The transmission lighting module uses LED matrix pixel to light up the road surface, so the entire light pattern is formed by splicing small light patterns. Due to the errors of parts and assembly, the light pattern cannot be spliced uniformly, and the splicing line is bright or dark.
[0055] 2. The traditional lighting module needs to use multiple LED matrices to light up, which will generate a large amount of heat, and the heat sink is a great challenge.
[0056] 3. The traditional lighting module needs complex LED drive to control the on-off of multiple LED chips, and the hardware cost is high.
[0057] The core of the present application is to disclose a lighting module to reduce the occurrence of the phenomenon of carding when moving to the dark area.
[0058] Another core of the present application is to disclose a car light comprising the above lighting module.
[0059] The technical solutions in the embodiments of the present application will be described clearly and completely in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.
[0060] As shown in Figures 1-2 , the present application discloses a lighting module, comprising a lamp panel 100, a lens unit 200, a light pattern baffle 300, a rotating unit 400 and a heat sink 500.
[0061] As shown in Figure 6 and Figure 16 , the lamp panel 100 is provided with a low beam light source 110 and a high beam light source 120, and the low beam light source 110 and the high beam light source 120 are preferably LED particles. The specific number of LED particles can be determined according to actual needs. As shown in Figure 2 , the lens unit 200 comprises a lens bracket 210 and an inner lens 220 and an outer lens 230 arranged on the lens bracket 210, and the lens bracket 210 is connected with the heat sink 500. Along the irradiation direction of the low beam light source 110 and the high beam light source 120, the inner lens 220 and the outer lens 230 are arranged in sequence, and the light pattern baffle 300 is arranged on the lens bracket 210 to form a low beam cutoff line, as shown in Figure 2 , the light pattern baffle 300 divides the lighting module into two parts, the upper half part realizes the low beam function, and the lower half part realizes the high beam function. Taking the high beam light source 120 as an example, as shown inFigure 7 As shown, the light emitted by the high beam light source 120 first irradiates to the inner lens 220, is emitted after being condensed by the inner lens 220, then irradiates to the outer lens 230, is emitted after being emitted by the outer lens 230, and irradiates to the road surface, and the A area shown in the figure is a dark area. The heat sink 500 is connected with the lamp panel 100 to dissipate heat for the lamp panel 100.
[0062] The rotating unit 400 is arranged in the light path irradiation direction of the high beam light source 120, and the rotating baffle 410 of the rotating unit 400 can shield the light emitted by the high beam light source 120 to form a dark area. When the intelligent identification system of the vehicle identifies an oncoming vehicle, the rotating baffle 410 shields the light emitted by the high beam light source 120 in the corresponding area to form a dark area of a corresponding size in the vehicle area, and a dynamic light pattern is formed according to the position of the oncoming vehicle to realize the ADB (adaptive driving beam) function of the vehicle.
[0063] The lighting module disclosed in the embodiment of the utility model, through setting rotating unit 400, rotating baffle 410 can shield the oncoming vehicle area in the irradiation direction of high beam light source 120, make the oncoming vehicle area in the vehicle driving lighting process is dark area, reduce the occurrence of dazzling phenomenon in the oncoming driving, can improve the safety of driving, compared with the way of lighting through LED matrix in the prior art, through the way of mechanical movement, can improve the uniformity of lighting light pattern, the dark area moves not jammed, the dark area moves continuously, and the light pattern bright-dark boundary is clear; at the same time, the number of LED particles can be reduced, the heat dissipation amount of the lighting module can be reduced, and the cost can be reduced.
[0064] It should be noted that the rotating unit 400 is connected with the intelligent identification system of the vehicle, the intelligent identification system can identify the information of the oncoming vehicle, and the rotating unit 400 can shield the light emitted by the high beam light source 120 according to the position and angle of the oncoming vehicle to form a dark area.
[0065] The lamp panel 100 and the heat sink 500 can be connected in a bolted manner, or in a clamped manner, or in an adhesive manner (such as using heat-conducting glue), or in other connection manners. The inner lens 220 and the outer lens 230 and the lens bracket 210 can be connected in a bolted manner, or in a clamped manner, or in an adhesive manner, and the specific connection manner is not limited.
[0066] Further, the rotating unit 400 can be arranged between the inner lens 220 and the outer lens 230, as shown in Figure 16 , or can be arranged outside the outer lens 230, where the outside means along the light path irradiation direction, the light irradiates to the outer lens 230, is emitted after being shielded by the rotating baffle 410 of the rotating unit 400, and irradiates to the road surface, as shown in Figures 17-18As shown. The following description uses the example of a rotating unit 400 positioned between the inner lens 220 and the outer lens 230.
[0067] Furthermore, the rotating unit 400 includes a rotating baffle 410, a rotating platform 430, and a driving assembly 420. The rotating baffle 410 is rotatably mounted on the rotating platform 430. The driving assembly 420 is connected to the rotating baffle 410 and the rotating platform 430 respectively to drive the rotating baffle 410 to rotate and drive the rotating platform 430 to move, so that the rotating baffle 410 changes position.
[0068] Furthermore, such as Figures 2-4 As shown, in some specific embodiments, the drive assembly 420 includes a first drive motor 421 and a second drive motor 422. Both the first drive motor 421 and the second drive motor 422 are mounted on the lens bracket 210. The first drive motor 421 is connected to the rotating baffle 410, and the second drive motor 422 is connected to the rotating platform 430. Specifically, the output shaft of the first drive motor 421 is connected to the rotating baffle 410 so that the rotating baffle 410 rotates synchronously with the first drive motor 421. It should be noted that the first drive motor 421 can also be connected to the rotating baffle 410 via a pulley or a gear assembly, as long as it can drive the rotating baffle 410 to rotate.
[0069] Both the first drive motor 421 and the second drive motor 422 are connected to the vehicle intelligent recognition system. When the vehicle intelligent recognition system detects an oncoming vehicle, the first drive motor 421 and the second drive motor 422 activate respectively, driving the rotating platform 430 to move and the rotating baffle 410 to rotate, thereby blocking the light emitted by the high beam source 120 at a corresponding position and forming a dark area of corresponding size. The arrangement of the first drive motor 421 and the second drive motor 422 enables dynamic light patterns.
[0070] Furthermore, such as Figures 3-4 As shown, a gear 423 is connected to the second drive motor 422. Specifically, the gear 423 is connected to the output shaft of the second drive motor 422. This connection can be achieved by a key or other means. The rotating platform 430 is provided with teeth that can mesh with the gear 423. When the second drive motor 422 rotates, it drives the rotating platform 430 to rotate, thereby changing the position of the rotating baffle 410.
[0071] like Figure 5 As shown, the rotating baffle 410 and the rotating platform 430 can move independently, such as Figure 5 a and Figure 5 As shown in b, when the position of the rotating platform 430 is fixed, the first drive motor 421 can drive the rotating baffle 410 to rotate, thereby changing the rotation angle of the rotating baffle 410; as Figure 5c- Figure 5 As shown in Figure d, the second drive motor 422 drives the rotating platform 430 to move. Taking the rotating platform 430 as an example (arc shape), the second drive motor 422 can drive the rotating platform 430 to rotate, causing the rotating baffle 410 to change position. Figures 7-14 As shown, the first drive motor 421 and the second drive motor 422 cooperate to enable the rotating baffle 410 to rotate at different angles in different positions, so as to generate corresponding dark areas according to the different positions of oncoming vehicles. Area A in the optical path diagram and the black area of the vehicle in the optical effect diagram are the formed dark areas. Figure 10 For example, in the image, the white rectangular area represents the high beam area, the arc-shaped area represents the low beam area, and the black area of the vehicle in the image corresponds to the high beam area. Figure 9 Area A in the diagram forms a dark zone, which reduces glare for oncoming vehicles.
[0072] Furthermore, such as Figure 5 and Figure 15 As shown, the rotating platform 430 can be arc-shaped, elongated, or any other shape, as long as the position of the rotating baffle 410 can be changed. An arc shape is preferred so that the rotating baffle 410 can make arc-shaped movements.
[0073] Furthermore, in order to make the rotation angle of the rotating baffle 410 more accurate and improve the control precision, the lighting module also includes an angle sensor. Specifically, the angle sensor can be set on the rotating baffle 410; and / or, the angle sensor can be set on the rotating platform 430.
[0074] Furthermore, the low beam source 110 and the high beam source 120 may use the same inner lens 220, or they may use different inner lenses 220 respectively. In some specific embodiments, the inner lens 220 includes a first inner lens and a second inner lens. The first inner lens is disposed in the optical path illumination direction of the low beam source 110, and the second inner lens is disposed in the optical path illumination direction of the high beam source 120.
[0075] In addition, this utility model embodiment also discloses a vehicle lamp, including the above-mentioned lighting module.
[0076] It should be noted that the various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.
