Moreover, the specific features, structures, materials or characteristics described may be combined in an appropriate manner in any one or more embodiments or examples.

[0027] The present application relates to an anti-glare multi-reflection high-efficiency light guide system, such as Figure 1-7 As shown, it includes a light source assembly, which is configured to be connected to one side of the light guide 2 and is used to emit light toward the light guide 2; the light guide 2 has a plurality of light guide cavities 18 arranged in a rectangular array; the light guide cavity 18 has a first light guide area, a second light guide area and a third light guide area arranged along the bottom; the first light guide area has a first light guide curved surface 10, and the second light guide area has a second light guide curved surface; the third light guide area has a light outlet hole connected to the light source assembly and an M-type light guide body 12 protruding from the periphery of the light outlet hole; the M-type light guide body 12 is configured such that an M-type light guide surface is formed on the outer side of the M-type light guide body 12, which can divert and guide the light output from the light outlet hole, and cooperates with the first light guide curved surface 10 and the second light guide curved surface 11 so that the light is reflected multiple times to form a three-way cross emission to the road surface.

[0028] The light source assembly is connected to one side of the light guide 2 and can emit light toward the light guide 2. The light is emitted toward the ground through the light guide 2 to illuminate the road surface. Traditionally, the light source panels 3 are divided into three types: flat, left-slanted and right-slanted, with a total of 6 light source panels 3, which leads to a complex structure of the entire light guide system. Because the light source assembly needs to be connected to the radiator, the weight of the entire radiator is increased, which is not conducive to processing, transportation and subsequent on-site assembly, and the maintenance cost and manufacturing cost are both high. Moreover, the left-slanted and right-slanted light source panels 3 will cause the emitted light source to be unable to be directly projected onto the road surface, causing the light source to diverge, and the utilization rate is greatly reduced. Glare may easily occur, causing discomfort to the human eye, which will seriously affect driving safety. The anti-glare multiple reflection high-efficiency light guide system of the present application adopts an integrated light source board 3, and a plurality of light guide cavities 18 are distributed by designing the light guide 2. Different regions in the light guide cavity 18 are provided with light guide areas of different structures, so that the light can be gathered after multiple reflections after diversion and directly projected to the ground, avoiding the complex structure caused by the oblique light source, the heavy heat sink, the cumbersome welding line and assembly process, greatly reducing the cost by 20%, and effectively reducing the glare by 10%, and improving the light utilization rate by more than 8%. Specifically: The light guide cavity 18 has a first light guide area and a second light guide area arranged opposite to each other along the side, and a third light guide area arranged along the bottom, so the third light guide area is located between the first light guide area and the second light guide area; wherein the first light guide area has a first light guide curved surface 10, the second light guide area has a second light guide curved surface 11, and the third light guide area has an M-shaped light guide body 12; a light guide surface is formed on the outer side of the M-shaped light guide body 12 to divert and guide the light output from the light exit hole, and the M-shaped light guide body 12 has an M-shaped light guide surface, so that when the light source passes through the bottom surface of the light guide 2, it is diverted through the M-shaped light guide surface to form three streams, wherein the light from the M-shaped light guide body 1 2 The light output in the middle is directed forward and directly projected onto the ground. The light output from the first side of the M-type light guide 12 is directed toward the second side after multiple reflections between the first light guide curved surface 10 and the M-type light guide surface. The light output from the second side of the M-type light guide 12 is directed toward the first side after multiple reflections between the second light guide curved surface 11 and the M-type light guide surface. The light emitted by the light source assembly is redistributed through convergence control, and the light intensity is cross-emitted from three directions, and then distributed in the front and rear directions through the first reflection surface 8 of the first reflection area and the second reflection surface 9 of the second reflection area described below, and then projected onto the lane. The light guide system of the present application can not only effectively improve the balanced output of light intensity and avoid the damage caused by glare to the observer, but also play a good role in collecting and controlling the large-angle light of the light source, shielding the "spill light" and "backlight", and can maximize the luminous flux of the lamp to be evenly and effectively focused on the road according to the road conditions. The downward luminous flux from the house side can reach more than 72%, and the luminous flux utilization rate is high. The large-angle stray light from the light source group 4 is effectively gathered and directly projected onto the road surface, further improving the light output efficiency of the light guide cavity 18 .

[0029] Furthermore, the light guide cavity 18 also includes a first reflection area and a second reflection area arranged opposite to each other along the side; the first reflection area includes a first reflection surface 8, and the second reflection area includes a second reflection surface 9; the three-way cross-emitting light is reflected by the first reflection surface 8 and the second reflection surface 9 and then emitted.

[0030] A first light guiding area is set on the left side of the circumference of the light guiding cavity 18, and a second light guiding area is set on the right side. A first reflection area is set on the front side and a second reflection area is set on the rear side. The M-type light guide body 12 is located in the middle of the sides surrounded by the first light guiding area, the second light guiding area, the first reflection area and the second reflection area. When the M-type light guiding surface on the M-type light guide body 12 splits the light source emitted by the light source assembly into three streams, the light source on the left side can be emitted obliquely to the right toward the second light guiding area under the action of the first light guiding curved surface 10 of the first light guiding area and the M-type light guiding surface. The light source on the right side can be output obliquely to the left toward the first light guiding area under the action of the second light guiding curved surface 11 of the second light guiding area and the M-type light guiding surface. The light source in the middle is emitted toward the front under the action of the M-type light guiding surface, forming three-way cross-emitting light, which is then further reflected by the first reflection surface 8 of the first reflection area and the second reflection surface 9 of the second reflection area. Figure 7 As shown, the light is redistributed in the front and rear directions, so that more light is projected onto the lane and a small amount of light is projected onto the non-motorized vehicle lane, thereby achieving a reasonable distribution of light intensity and effectively controlling the light in each area to avoid light divergence or large intensity differences, avoid excessively bright light sources or glare due to inappropriate brightness distribution, and effectively prevent glare from causing discomfort to the observer or reducing visual ability.

[0031] Furthermore, the first reflection surface 8 and the second reflection surface 9 are planar structures, and the first reflection surface 8 and the second reflection surface 9 are obliquely arranged on the bottom wall of the light guide cavity 18 .

[0032] In order to make the three-way crossed light be more directly projected onto the motor vehicle lane and less light be projected onto the non-motor vehicle lane, the first reflecting surface 8 and the second reflecting surface 9 are designed to have a planar structure and are arranged obliquely to the bottom surface of the light guide cavity 18 to form a certain reflection angle, so that the three-way crossed light is emitted at a large angle under the reflection of the first reflecting surface 8 and the second reflecting surface 9, and more light is directly projected onto the motor vehicle lane, which can control the overflow of stray light while evenly and effectively focusing the luminous flux of the lamp on the road.

[0033] The first reflecting surface 8 and the second reflecting surface 9 of the present application cooperate with the first light guiding area and the second light guiding area, and are arranged in a single or several arrays. The first reflecting surface and the second reflecting surface can be full mirror reflection, or full diffuse reflection surface, or a combination of diffuse reflection surface and mirror surface. It can be formed by injection molding and then coating, or by splicing aluminum plates. The present application adopts a reflective light distribution design, which plays a good control role on the large-angle light emitted by the light source. By shielding the "spill light" and "backlight", the luminous flux of the lamp can be evenly and effectively focused on the road according to the road conditions to the maximum extent. The downward luminous flux from the side of the house can reach more than 72%, and the luminous flux utilization rate is high. The reflective type (grille cup) is 26% higher than the refractive type (lens), which can greatly improve the lighting efficiency.

[0034] like Figure 8 As shown, it is the light distribution curve of the light guide area and the reflection area involved in this application, such as Fig. 9 As shown in the figure, it is the light intensity diagram of the light-guiding area and the reflection area. Fig.10 The figure shows the illumination diagram of the light-guiding area and the reflection area. As can be seen from the above figure, the light distribution angle of the duct system of the present application can be more concentrated and spread laterally to both sides, which can increase the range of irradiating the road surface, realize the redistribution of light intensity, and meet the needs of road lighting distribution. Thereby more light is projected onto the lane, and a small amount of light is projected onto the non-motorized vehicle lane, thereby meeting the conditions for the use of street lamps; it is more in line with the visual habits of drivers, and makes full use of the characteristics of the human eye that is sensitive to brightness but cannot perceive illumination. An equal brightness light distribution design is adopted to eliminate visual bright spots and dark spots on the road surface, making road personnel feel comfortable, while improving the illumination under the lamp to obtain excellent lighting indicators.

[0036] It should be noted that there are three light exit holes in a light guide cavity 18, namely the first light exit hole, the second light exit hole and the third light exit hole, and there are multiple light source groups 4 on the first light source board 3, each light guide cavity 18 has a group of light source groups 4, each light source group 4 includes three light source groups 4, namely the first light source group 41, the second light source group 42 and the third light source group 43, the first light source group 41, the second light source group 42 and the third light source group 43 are provided with LED light sources, the number of which ranges from 1 to 10, and are reflow soldered on the light source board 3, and the light source board 3 is fastened to the waterproof radiator 5 described below by bolts; and the number of LED lamps connected to the light source board 3 to which the entire light guide 2 is connected ranges from 1 to 500; preferably, the number of light exit holes in the entire light guide 2 ranges from 1 to 500.

[0037] like Figure 3 As shown, the first light source group 41 is arranged on the left side, the second light source group 42 is arranged in the middle, and the third light source group 43 is arranged on the right side. Three light exit holes are opened at the bottom of the light guide cavity 18, namely the first light exit hole on the left side, the second light exit hole in the middle and the third light exit hole on the right side. The light source board 3 is connected to one side of the light guide 2, the first light source group 41 on the light source board 3 is connected in the first light exit hole, the second light source group 42 is connected in the second light exit hole, and the third light source group 43 is connected in the third light exit hole, so that the light sources can be emitted from the left side, the middle and the right side of the light guide 2 respectively.

[0038] Furthermore, the M-type light guide 12 includes a first light guide 121 and a second light guide 122 which are symmetrically arranged. The first light guide 121 is arranged between the first light source group 41 and the second light source group 42, and the second light guide 122 is arranged between the second light source group 42 and the third light source group 43; the light output by the first light source group 41 is output toward the side of the third light source group 43 after multiple reflections between the first light guide 121 and the first light guide curved surface 10, and the light output by the third light source group 43 is output toward the side of the first light source group 41 after multiple reflections between the second light guide 122 and the second light guide curved surface 11; the light output by the second light source group 42 is output straight between the first light guide 121 and the second light guide 122.

[0039] Furthermore, if Figure 4 and Figure 5 As shown, the first light guiding curved surface 10 has a plurality of connected ellipsoidal curved surfaces; and the second light guiding curved surface has a plurality of connected ellipsoidal curved surfaces.

[0040] like Figure 3As shown, the M-shaped light guide 12 has two first light guides 121 and second light guides 122 with the same structure and symmetrically arranged in the light guide 2. The first light guide 121 and the second light guide 122 are separated by a preset distance, and the structure of the first light guide 121 is the same as that of the second light guide 122. Figure 4 and Figure 5 In the orientation shown, the right side of the first light guide body 121 is a first light guide surface 13 with a planar structure, the left side of the first light guide body 121 is a second light guide surface 14 with an arcuate shape, the left side of the second light guide body 122 is a third light guide surface 15 with a planar shape, and the right side of the second light guide body 122 is a fourth light guide surface 16 with an arcuate shape, wherein the first light guide surface 13 and the third light guide surface 15 are arranged relative to each other at a preset distance, and the first light guide surface 13 and the third light guide surface 15 are inclinedly arranged on the bottom wall of the light guide cavity 18; the second light guide surface 14 is arranged toward the first light guide curved surface 10, and the fourth light guide surface 16 is arranged toward the second light guide curved surface.

[0041] like Figure 6 As shown, the tracking path of the light source through the first light guiding area and the second light guiding area of ​​the light guide 2 is: Since the first light guide 121 is disposed between the first light source group 41 and the second light source group 42, when the first light source group 41 outputs light, the light will be redistributed after multiple reflections between the multi-ellipsoidal first light guide curved surface 10 and the arc-shaped second light guide surface 14, and the light is controlled to be output obliquely from the right; Since the first light guide 121 is disposed between the first light source group 41 and the second light source group 42, and the second light guide 122 is disposed between the second light source group 42 and the third light source group 43, when the second light source group 42 outputs light, the light will be gathered between the first light guide surface 13 in a planar shape and the third light guide surface 15 in a planar shape, and the light will be redistributed after the light intensity is redistributed, and the light will be controlled to be output from the front direction; Since the second light guide 122 is arranged between the second light source group 42 and the third light source group 43, when the third light source group 43 outputs light, the light will be redistributed after multiple reflections between the second multi-ellipsoidal light guide surface 11 and the arc-shaped fourth light guide surface 16, and the light is controlled to be output obliquely from the left.

[0042] The first light guide 121 and the second light guide 122 of the M-type light guide 12 form an M-shaped structure, and the first light guide surface 13 and the second light guide surface 14 of the first light guide 121, the third light guide surface 15 and the fourth light guide surface 16 of the second light guide 122 form an M-shaped light guide surface. This M-shaped light guide surface plays a vital role in the entire light guide system. When controlling the light emitted by the first light source group 41 and the third light source group 43, it can effectively raise the emission angle of the lower side light, so that the light can be directly projected onto the road surface, thereby improving the light emission efficiency of the light guide cavity 18; and when the second light source group 42 emits light, it can play a good role in gathering the large-angle light emitted by the second light source group 42, avoiding "spill light" and "backlight", and can maximize the luminous flux of the lamp to be evenly and effectively focused on the road according to road conditions, so that the downward luminous flux from the house side can reach more than 72%, and the luminous flux utilization rate is high. The large-angle stray light of the light source group 4 is effectively gathered, so that it is effectively gathered and directly projected onto the road surface, further improving the light output efficiency of the light guide cavity 18. Moreover, by redistributing the light intensity of the first light source group 41, the second light source group 42 and the third light source group 43, it is possible to control the stray light and avoid uneven light intensity, avoid the occurrence of glare, avoid discomfort to the driver's eyes, and improve the safety of vehicle operation; in summary, the present application realizes the dispersion of light points and reasonable light distribution, with low light flux density, which can effectively control glare, reduce light pollution, and provide a comfortable and healthy lighting environment; more light sources are projected onto the motor vehicle lane, eliminating visual bright spots and visual dark spots on the road surface, making road personnel feel comfortable, while improving the illumination under the lamp and obtaining excellent lighting indicators.

[0044] The heat sink can be formed of die-cast aluminum alloy, die-cast magnesium alloy, cold-forged magnesium alloy, or cold-forged aluminum alloy. The respirator 6 is used to balance the pressure difference between the light source cavity and the atmosphere. Otherwise, after the light source group 4 emits light and heats for a period of time, it turns off and cools down, and a negative pressure is formed in the light source cavity, which will absorb moisture and water vapor in the weak link of the seal.

[0045] As a preferred embodiment, the anti-glare multiple reflection high-efficiency light guide system further includes a waterproof joint 7 and a wire; the waterproof radiator 5 is provided with a connection hole for passing the wire; one end of the wire is connected to the light source board 3, and the other end of the wire passes through the connection hole and is blocked by the waterproof joint 7. The waterproof joint 7 is used for waterproofing when the wire passes through the radiator.

[0047] The adhesive is glass glue, and the glass piece is coated in the groove. By placing the tempered glass 1 on the multi-reflection high-efficiency light guide 2, the glass glue in the groove of the waterproof heat sink 5 is firmly bonded and sealed. The tempered glass 1 is printed with ink, which can play a shielding role, making the LED module simple and beautiful. The elastic clamp 17 is used to clamp the tempered glass 1 to prevent the tempered glass 1 from falling and injuring people when the glass glue fails for some reason.
