DETAILED DESCRIPTION

[0027] The utility model provides a show wide ground car lamp, in order to make the purpose, technical scheme and effect of the utility model more clear, explicit, the following refers to the drawing and raises example and the utility model is further detailed explanation. It should be understood that the specific embodiment described here is only used to explain the utility model, and is not used to limit the protection scope of the utility model.

[0028] Please refer to Figures 1 to 7 The utility model provides a show wide ground car lamp, including vertical light source circuit board 1, set up on the light source circuit board 1 front end surface's reflector 2, the first LED patch lamp pearl 11 that surrounds the reflector 2's periphery arrangement and is forward irradiation, and the second LED patch lamp pearl 12 that sets up in the reflector 2 and the first LED patch lamp pearl 11 below and is downward irradiation, the reflector 2 and the first LED patch lamp pearl 11 front is equipped with the first light guide 3, the first light guide 3 is used to guide a part of the light that the first LED patch lamp pearl 11 emits to emit light outward, and guide another part's light that the first LED patch lamp pearl 11 emits to refract to the reflector 2, then the first light guide 3 recycles and makes the light that the reflector 2 reflects redeflects and refracts back to the reflector 2, makes the light gradually converge to the center of the reflector 2.

[0029] The utility model discloses a show wide ground car lamp, including vertical light source circuit board 1, set up on the light source circuit board 1 front end surface's reflector 2, the first LED patch lamp pearl 11 that surrounds the reflector 2's periphery arrangement and is forward irradiation, and the second LED patch lamp pearl 12 that sets up in the reflector 2 and the first LED patch lamp pearl 11 below and is downward irradiation, the reflector 2 and the first LED patch lamp pearl 11 front is equipped with the first light guide 3, the first light guide 3 is used to guide a part of the light that the first LED patch lamp pearl 11 emits to emit light outward, and guide another part's light that the first LED patch lamp pearl 11 emits to refract to the reflector 2, then the first light guide 3 recycles and makes the light that the reflector 2 reflects redeflects and refracts back to the reflector 2, makes the light gradually converge to the center of the reflector 2.

[0030] The wide-indication ground-illumination vehicle lamp provided by the utility model has good wide-indication warning and ground-illumination functions, only needs to arrange a small number of first LED patch lamp beads 11 in one circle around the reflecting surface 2, greatly reduces the number of lamp beads compared with the wide-indication lamp part densely covered with a large number of LED lamp beads in the prior art, and further reduces energy consumption. Meanwhile, the reduction of the number of lamp beads makes the assembling and maintenance of the lamp more convenient and reduces the overall cost. The first LED patch lamp bead 11, the first light guide 3 and the reflecting surface 2 cooperate with each other, not only directly emit light outward from the first LED patch lamp bead 11 to realize the basic wide-indication warning function, but also create a deep three-dimensional light effect on the reflecting surface 2 through the unique light guiding and reflecting mechanism between the first light guide 3 and the reflecting surface 2, which makes the wide-indication warning effect of the vehicle lamp more remarkable, pedestrians and drivers of nearby vehicles can clearly perceive the width profile of the truck at a long distance, and further reduces the risk of scratching and collision.

[0031] Specifically, the first light guide 3 comprises a multiple-refraction light-transmitting layer 31, a light-guiding surrounding edge 32 arranged around the periphery of the multiple-refraction light-transmitting layer 31, and an inner corner layer 33 connecting the multiple-refraction light-transmitting layer 31 and the light-guiding surrounding edge 32, the multiple-refraction light-transmitting layer 31 can be orthogonally projected on the reflecting surface 2, the inner corner layer 33 is provided with a first inclined surface 331 inclined towards the reflecting surface 2 and a second inclined surface 332 facing the light-guiding surrounding edge 32, and the first LED patch lamp bead 11 is closely arranged on the back surface of the light-guiding surrounding edge 32.

[0032] When the first LED patch lamp bead 11 starts to emit light, the light enters the light-guiding surrounding edge 32. In the light-guiding surrounding edge 32, the light is split: part of the light is directly dispersed and irradiated outward along the preset path of the light-guiding surrounding edge 32 to realize the basic wide-illumination function of the vehicle and help pedestrians and vehicles around to identify the width of the vehicle. Another part of the light is guided to the inner corner layer 33 by the light-guiding surrounding edge 32. The inner corner layer 33 has a unique inclined surface structure composed of the first inclined surface 331 and the second inclined surface 332. When the light contacts the first inclined surface 331, the propagation direction is changed based on the refraction principle of light, and then the light is further guided through the second inclined surface 332 to realize the inward reflection to the reflecting surface 2. The reflecting surface 2 reflects the light to the multiple-refraction light-transmitting layer 31, and the multiple-refraction light-transmitting layer 31 guides the light reflected by the reflecting surface 2 back to the reflecting surface 2 by virtue of the inner arc surface. In this circulation process, the light continuously converges to the center of the reflecting surface 2, and further creates a deep three-dimensional light effect on the reflecting surface 2, which significantly enhances the wide-indication warning effect.

[0033] In an embodiment, the light-reflecting surface 2 is in a rectangular structure, and the first LED patch lamp beads 11 are arranged at intervals. The regular shape of the rectangular light-reflecting surface 2 is conducive to uniform reflection of light, and in combination with the interval arrangement of the first LED patch lamp beads 11, the problem of excessive concentration or dispersion of light is avoided. In the process of converging light to the center of the light-reflecting surface 2, a more uniform and deep three-dimensional light effect is created, the visual range of the width-indicating warning is expanded, and at the same time, the light intensity at each angle is more balanced, thereby improving the overall illumination performance of the vehicle lamp.

[0034] In another embodiment, the light-reflecting surface 2 is in a circular structure, and the first LED patch lamp beads 11 are arranged at intervals. The circular light-reflecting surface 2 can guide the light to converge and reflect around the center. In this process, the light emitted by the interval-arranged first LED patch lamp beads 11 creates a unique and deep three-dimensional light effect on the light-reflecting surface 2, which is focused on the center of the circle. This light effect not only has high recognizability, but also enhances the visual impact, so that the outline of the truck is clearly visible under various light conditions, further improving the width-indicating warning effect.

[0035] It should be noted that the light-reflecting surface 2 is not limited to rectangular and circular shapes, but can also be regular shapes such as polygons (such as triangles, hexagons, etc.) or irregular shapes.

[0036] The light source circuit board 1 and the first light guide 3 are embedded in the shell 4, and the shell 4 is mounted on the hanging plate 5 by screws. The light source circuit board 1 and the first light guide 3 are embedded in the shell 4, and the shell 4 provides physical protection for them, effectively preventing dust, rainwater and other impurities from entering, reducing the risk of short circuit or failure caused by environmental factors, and prolonging the service life. At the same time, the screw connection tightly fixes the shell 4 and the hanging plate 5, and the stable mounting structure ensures that the vehicle lamp will not loosen during driving due to bumps and vibrations, thereby maintaining a stable working state.

[0037] The hanging plate 5 is provided with a hanging hole 51, which is matched with the mounting mode of the screw, thereby greatly simplifying the installation process. The maintenance personnel only need to pass the screw through the hanging hole 51 and tighten it, and the vehicle lamp installation can be quickly completed. This not only reduces the installation time and labor cost, but also facilitates the installation of different vehicle models, thereby improving the product versatility.

[0038] In this embodiment, the light-reflecting surface 2 is specifically a mirror, which has a very high reflectivity, ensures the accuracy of the reflected light angle, and can more accurately cooperate with the first light guide 3 to create a more uniform and deep three-dimensional light effect, thereby improving the width-indicating warning recognizability in all directions and enabling pedestrians and vehicles around the vehicle to more clearly perceive the outline of the vehicle.

[0039] Of course, the reflective surface 2 can also be a reflective coating applied on a common substrate, such as a reflective paint containing glass beads or metal oxides. This way, the structural advantages of the existing substrate can be utilized, and the reflective performance can be flexibly adjusted by the choice of coating, reducing costs.

[0040] In a preferred embodiment, see Figures 1 to 3 , a second light guide 6 is arranged below the second LED patch lamp bead 12, which is used to collect and emit light downward. The light collecting design of the second light guide 6 makes the light emitted by the second LED patch more concentrated downward, effectively improving the ground illumination intensity and widening the ground illumination range. In the night or in areas with poor lighting conditions, the driver can more clearly see the ground conditions around the vehicle, including obstacles, potholes, pedestrians, and small animals, etc., so as to make timely judgments and avoid crushing and collision accidents, greatly improving the safety of vehicle driving.

[0041] By the light collecting treatment of the second light guide 6, the scattering and diffusion of light during transmission can be reduced, and the utilization rate of light energy can be significantly improved. This not only can reduce the energy consumption of the second LED patch while ensuring the lighting effect and prolong its service life, but also can further optimize the energy utilization efficiency of the entire vehicle lamp system in cooperation with the first LED patch and the mirror reflective surface 2, etc., and reduce the overall energy consumption of the vehicle.

[0042] Specifically, the second light guide 6 includes a light guide layer 61 and a plurality of lower convex lenses 62 arranged in parallel at the bottom of the light guide layer 61. The light guide layer 61 is responsible for collecting and preliminarily guiding the light emitted by the second LED patch, and the lower convex lenses 62 further converge the light. The two work together to effectively reduce the loss of light during transmission and significantly improve the utilization rate of light energy. The number of lower convex lenses 62 is the same as that of the second LED patch lamp beads 12 and corresponds one-to-one, that is, each lower convex lens 62 corresponds to a second LED patch, which can accurately collect the light emitted by a single lamp bead. Compared with the traditional overall light collecting design, this one-to-one accurate matching avoids the cross interference of light, significantly improves the light collecting effect. When illuminating the ground around the vehicle, the light focused by each lower convex lens 62 works together to make the ground illumination more uniform without obvious dark areas or bright spots, greatly improving the lighting quality and making the driver's judgment of the ground conditions around the vehicle more accurate, further reducing the risk of accidents.

[0043] When the installation position of the wide-beam headlamp is high, the light emitted by the second LED patch may originally directly irradiate the eyes of pedestrians, electric vehicle drivers and motorcycle drivers, causing glare interference. Therefore, the second light guide 6 further comprises a return reflector 63 connected with the outer edge of the light guide layer 61 and vertically arranged, which changes the propagation path of the light. It can capture the light that may originally directly irradiate the eyes of road users, and change the direction by reflection, avoiding the interference of glare on their vision, creating a safer travel environment and reducing the risk of traffic accidents caused by glare.

[0044] Preferably, the first light guide 3 and the second light guide 6 are integrally formed, on the one hand, reducing the number and complexity of molds and reducing production manufacturing costs; on the other hand, without the need for complicated component positioning and connection operations during assembly, shortening the production cycle, improving production efficiency, and enhancing the cost competitiveness of the product in the market.
