[0001] The present invention relates to the technical field of road light source steering, and in particular to a single light source steering device for roads and a light source steering method. Background Art

[0002] At present, lighting devices on roads are mainly used to provide a relatively uniform lighting coverage to ensure the driver's clear vision at night or in low lighting conditions. However, such devices are often unable to specifically enhance the lighting of the turning section of the road, resulting in the driver's vision being blocked on the turning section, which may increase the risk of traffic accidents. Similarly, the laser guidance devices on existing roads only roughly guide the straight direction of the road, but cannot effectively guide or remind the driver of the turning situation of the road ahead, so as to remind the driver to pay attention to the risks in advance.

[0003] Therefore, it is difficult for existing road lighting devices or laser guidance devices to flexibly adjust the light distribution or laser guidance according to the specific geometry of the road and the turning angle, and therefore cannot fully meet the needs for different lighting effects or laser guidance in complex road environments.

[0004] To this end, in view of the deficiencies of the prior art, the present invention proposes a new type of single-light source steering device for roads, which aims to provide targeted lighting or laser guidance for road turning conditions, thereby improving the driver's vision and enhancing road safety.

DETAILED DESCRIPTION

[0020] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the specific implementation mode, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0021] The technical solutions provided by various embodiments of the present invention are described in detail below in conjunction with the accompanying drawings.

[0022] Reference Figures 1 to 9 As shown, an embodiment of the present invention provides a single light source steering device for roads, which mainly includes a lamp pole 1, a cover 2, a first distance adjustment component 5 and a dimming angle mechanism 6.

[0023] The cover 2 is installed on the top of the lamp pole 1 through a set of tilt adjustment mechanisms 3, and has multiple layers of light source emitting layers 4 arranged in vertical columns inside. The opening side of each light source emitting layer is provided with a longitudinally arranged cylindrical mirror 41, and a light emitter 42 is installed in the bottom or top light source emitting layer; the light emitted by the light emitter 42 is formed into multiple groups of light beams located in the multiple layers of light source emitting layers respectively through the light source splitting structure provided in the cover 2, and each group of light beams is emitted through the cylindrical mirror 41 in the corresponding light source emitting layer to form a fan-shaped light surface; Therefore, the cover 2 is installed on the top of the lamp pole 1 through a set of tilt adjustment mechanisms 3. This installation method allows the cover 2 to change its angle relative to the lamp pole 1, thereby adjusting the angle of the internal light source emission layer to meet different lighting or application requirements.

[0024] In some practical applications, refer to Figure 1 As shown, the tilt adjustment mechanism 3 includes a bracket 31 mounted on the lamp pole 1, one side of the top of the bracket 31 is hinged to the cover 2, and an electric telescopic rod 32 is also provided between the bracket 31 and the cover 2, and the base and the telescopic end of the electric telescopic rod 32 are respectively hinged to the bracket 31 and the cover 2, so that the cover 2 can be pushed to move to change its angle through the operation of the electric telescopic rod 32, so as to achieve the angle adjustment of the multi-layer light source emission layer. When the light emitter 42 is a laser light emitter 42, the single light source steering device is used in the field of highway laser lighting reminders, and the fan-shaped light surface emitted by the light source emission layer needs to be flush with the road surface inclination, so as to form multiple fan-shaped laser surfaces parallel to the road surface in the air to remind the driver of the road inclination in front of the road surface; when the light emitter 42 is an illumination light emitter 42, the single light source steering device is used in the field of road lighting or reminders, in which case, the fan-shaped light surface emitted by the light source emission layer points to the road surface in front.

[0025] The first distance adjustment component 5 is used to adjust the interval between two adjacent light source emission layers; by changing the longitudinal spacing, the distribution of the fan-shaped light surface emitted by each light source emission layer on the road surface or in the air can be controlled to achieve different lighting presentation effects such as spaced light paths or full light paths. When the light emitter 42 is a lighting light emitter 42, the spaced light path can improve the eye-catching effect in the lighting field and attract the attention of drivers, etc.; the full light path can provide a more uniform and comprehensive lighting effect, enhancing visibility and safety.

[0026] The dimming angle mechanism 6 is configured with at least two groups, and is installed in different light source emission layers respectively, to adjust the left and right emission angles of the fan-shaped light surface in the corresponding light source emission layer, so that the illumination range and angle of the light in the horizontal direction can be flexibly controlled, so that the lighting or light path can be adapted to the actual direction of the road, the turning situation, etc. Specifically, by changing the left and right inclination angles of the multi-layer light source emission layer, and letting the fan-shaped light source emitted by the light source emission port of the lowest layer point to the forward direction of the current road, the multi-layer light source emission port above increases the angle in sequence, so that multiple groups of fan-shaped light surfaces with different inclination angles can be emitted, thereby forming a light path adapted to the turning angle of the road ahead. When applied in the field of laser irradiation, multiple laser lines of progressive turning can prompt the driver in advance the turning situation of the road ahead and the approximate turning angle; when applied in the field of lighting irradiation, the light source is hit on the road surface, and the synergistic effect of multiple light source emission layers can illuminate the road surface at the entire turning point, ensuring the safety of vehicles driving on the turning section.

[0027] In summary, the single-light source steering device can achieve different lighting light path distributions and angles through a variety of adjustment methods (such as angle adjustment, spacing adjustment, etc.), which can provide eye-catching interval light paths, as well as comprehensive full light paths, and can also adapt to road turning conditions for targeted lighting, meeting the diverse needs for lighting effects in different road scenes. In addition, by forming a light path that matches the turning angle on the turning section, whether it is laser illumination prompts or lighting to illuminate the road surface, it can help the driver better see or judge the road conditions ahead, understand the road conditions in advance, and effectively reduce traffic accidents caused by poor visibility at road turns.

[0028] Moreover, the present application adopts a single light source combined with splitting, adjustment and other structures to realize multiple groups of light paths with different angles and distributions. Compared with the traditional design of multiple independent light sources, it may save more energy, reduce costs, and facilitate overall maintenance and management while ensuring the lighting effect.

[0029] In some practical applications, refer to Figure 4 and Figure 6As shown, the light source spectroscopic structure includes a collimating lens 43 and a plurality of beam splitters 44, and each layer of the light source emission layer is correspondingly configured with a beam splitter 44; the collimating lens 43 is fixedly arranged in the light source emission layer where the light emitter 42 is located, and the light source emitted by the light emitter 42 is collimated into a parallel light beam by the collimating lens 43, and the parallel light beam is divided into a transmitted light beam and a reflected light beam by the beam splitter 44 arranged along the direction of the parallel light beam, and the transmitted light beam passes through the cylindrical mirror 41 in the corresponding light source emission layer to form the fan-shaped light surface, and the reflected light beam passes through the beam splitters 44 and cylindrical mirrors 41 in other light source emission layers in sequence to form a fan-shaped light surface in each layer of the light source emission layer. As shown in the figure, the beam splitter 44 is configured to be tilted 45° to the right, so that the transmitted light beam can maintain its original direction and continue to be emitted forward, while the reflected light beam is refracted by the beam splitter 44 and emitted vertically upward to enter the beam splitter 44 in the upper light source emission layer. Through the sequential transmission and refraction of multiple beam splitters 44, a fan-shaped light surface can be formed at the opening end of each light source emission layer.

[0030] In some practical applications, refer to Figure 4 , Figure 5 and Figure 7 As shown, the dimming angle mechanism 6 includes a turntable 61, a turning housing 62 and a rotation driving mechanism.

[0031] The turntable 61 is rotatably connected to the bottom wall of the corresponding light source emission layer; the steering housing 62 is fixedly mounted on the turntable 61 to rotate with the turntable 61, and the spectroscope 44 is mounted in the steering housing 62 to receive the reflected light beams injected from other light source emission layers; the cylindrical mirror 41 is mounted at the open end of the steering housing 62. The rotation drive mechanism is installed in the light source emission layer to drive the turntable 61 to rotate. Specifically, the rotation drive mechanism includes a driving gear 63, a driven gear 64, a motor bracket 65 and a rotation drive source 66; the driven gear 64 is sleeved on the outer edge of the turntable 61, the rotation drive source 66 is fixed inside the light source emission layer through the motor bracket 65, and the output shaft of the rotation drive source 66 is coaxially connected with the driving gear 63 to drive the driving gear 63 to rotate, and the driving gear 63 and the driven gear 64 are meshed and connected. It should be noted that a channel for the reflected light beam in the next layer to pass through is provided between two adjacent light source emission layers, as can be seen from the figure.

[0032] When it is necessary to adjust the left and right emission angles of the fan-shaped light surface in the corresponding light source emission layer, the rotation drive source 66 (usually a motor) is started, and the output shaft of the rotation drive source 66 starts to rotate, driving the driving gear 63 coaxially connected thereto to rotate. Since the driving gear 63 and the driven gear 64 are meshed and connected, according to the gear transmission principle, the rotation of the driving gear 63 will drive the driven gear 64 to rotate accordingly, and the driven gear 64 is sleeved on the outer edge of the turntable 61, so the rotation of the driven gear 64 will drive the turntable 61 to rotate around the connection axis between it and the bottom wall of the light source emission layer (the connection axis should be coaxial with the center line of the two adjacent beam splitters 44 to ensure that the reflected light beam emitted by the beam splitter 44 of the next layer can still be directly projected on the center of the beam splitter 44 after rotation). The rotation of the turntable 61 will cause the steering housing 62 fixed thereon to rotate synchronously, and the angle of the beam splitter 44 in the steering housing 62 will change accordingly, which changes the processing direction of the light beam after the beam splitter 44 receives the reflected light beam in the emission layer of other light sources, thereby realizing the function of flexibly changing the irradiation angle of the fan-shaped light surface in the horizontal direction according to actual needs, so as to better adapt to different road directions, turning conditions and other scenes, and provide precise light path adjustment for applications such as lighting or laser irradiation.

[0033] In some actual cases, such as Figure 4 and Figure 5 As shown, the light source emission layer is configured with three groups, and the light emitter 42 is located in the bottom light source emission layer, and the dimming corner mechanism 6 is configured with two groups and is respectively located in the two upper light source emission layers.

[0034] In some practical applications, based on any of the above embodiments, the distance between each cylindrical mirror 41 and its corresponding beam splitter 44 can be adjusted. Specifically, the cylindrical mirror 41 is mounted on a set of second distance adjustment components 7, so that the distance between it and the corresponding beam splitter 44 can be adjusted by the second distance adjustment components 7.

[0035] Reference Figure 2 and Figure 8As shown, the second distance adjustment component 7 includes at least a rectangular frame 71, which has a detachable top plate 711, and grooves 713 are provided on the opposite sides of the top plate 711 and the bottom plate 712 of the rectangular frame 71, and the two ends of the cylindrical mirror 41 are respectively embedded in the grooves 713 on the top plate 711 and the bottom plate 712. The slide rail 72 is installed on the steering housing 62, and one side of the rectangular frame 71 is slidably connected to the slide rail 72 to enable the cylindrical mirror 41 to move toward or away from the spectrometer 44; the sliding plate 73 is attached to the outer wall of the steering housing 62; the threaded end of the locking bolt 74 passes through the sliding plate 73 and the guide groove 621 on the steering housing 62 and is threadedly connected to the threaded hole 714 on the rectangular frame 71; when the locking bolt 74 is not locked, the locking bolt 74 is pushed to move along the guide groove 621 to drive the rectangular frame 71 to move; when the locking bolt 74 is locked on the sliding plate 73, the rectangular frame 71 is locked.

[0036] When the distance between the cylindrical mirror 41 and the beam splitter 44 needs to be adjusted, the locking bolt 74 is first loosened to be in an unlocked state. At this time, the operator can push the locking bolt 74 along the guide groove 621 on the steering housing 62. Since the locking bolt 74 is connected to the rectangular frame 71 through a thread, the locking bolt 74 will drive the rectangular frame 71 to slide along the slide rail 72 during the pushing process. The movement of the rectangular frame 71 will drive the cylindrical mirror 41 installed on the internal slot 713 thereof to move synchronously, so that the cylindrical mirror 41 changes its position in the direction of approaching or moving away from the beam splitter 44, and the distance between the two is adjusted to meet different light path adjustment requirements, such as adjusting the distance according to the actual lighting scene's requirements for the focusing, divergence and other effects of the light beam (when lighting, the light beam needs to diverge, while when laser prompting, the laser beam has a slight relative focus, and the angle of the fan beam formed should be smaller to improve the conspicuousness). After adjusting the cylindrical mirror 41 to a suitable distance, in order to ensure that its position is fixed and to avoid position changes caused by external factors (such as vibration, slight shaking during equipment operation, etc.) that affect the stability of the optical path, it is necessary to tighten the locking bolt 74 so that it is locked on the sliding plate 73. Through the threaded fastening effect between the locking bolt 74 and the rectangular frame 71 and the close fit with the sliding plate 73, the movement of the rectangular frame 71 can be limited, so that the cylindrical mirror 41 is stably locked in the current position, ensuring that the entire optical path system can operate stably according to the adjusted state and maintain the corresponding lighting or optical path effect.

[0037] Therefore, in this embodiment, through this structural design, the distance between the cylindrical mirror 41 and the beam splitter 44 can be conveniently and flexibly adjusted to adapt to a variety of different practical application scenarios and light path requirements. Whether it is necessary to enhance the convergence effect of the light beam, expand the scattering range of the light beam, or make fine light path adjustments according to different road conditions, lighting area characteristics, etc., it can be achieved by adjusting the distance, which greatly improves the adaptability of the device to different situations.

[0038] A road light source steering method can be implemented using the above-mentioned single light source steering device, and specifically includes the following steps: S1: multiple layers of longitudinally arranged light source emission ports (equivalent to the above-mentioned light source emission layer) are provided, and the angle between the multiple layers of light source emission ports and the lamp pole 1 is changed so that the fan-shaped light source emitted by the light source emission port is flush with the inclination of the road surface or points to the road surface; S2: By adjusting the longitudinal spacing between different light source emission ports, the fan-shaped light source emitted by the light source emission port forms an interval light path or a full light path on the road surface or in the air; S3: By changing the left and right tilt angles of the multi-layer light source emission ports, the fan-shaped light source emitted by the bottom light source emission port is pointing to the direction of the current road, and the multi-layer light source emission ports above increase the angle in sequence to emit multiple groups of fan-shaped light sources with different inclinations, forming a light path that matches the turning angle of the road ahead.

[0039] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment as above, it is not used to limit the present invention. Any technical personnel in this field can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention. However, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
