Description

Technical Field

[0001] This utility model relates to the field of light-emitting devices for road traffic safety, specifically to a perimeter-enhanced light-distribution type buried solar LED light-emitting road stud. Technical Background

[0002] In-ground solar-powered luminous road studs, sometimes called solar-powered raised pavement markers or solar ground lights, are installed with their main body below the ground reference surface buried in the road surface, while the top surface above the ground reference surface is exposed and flush with or slightly higher than the road surface. They have the function of storing solar energy during the day and using solar energy to power the luminous device at night. They can provide visual guidance or prompts for drivers and pedestrians, and can also serve as auxiliary road lighting equipment.

[0003] Existing buried solar-powered illuminated road studs mainly use LED light source groups in their front and rear light-emitting slots as the main light source. After matching with the optical structure on the LED light-emitting slots, they emit light at a small angle, which is conducive to long-range illumination. They only provide illumination indication and guidance functions for motor vehicle drivers. However, when approaching the road studs from a distance, there is a lack of brightness and illumination angle at close range, resulting in poor illumination effect for non-motorized vehicle drivers and pedestrians.

[0004] With social progress and the development of transportation, there is an increasing number of roads where motor vehicles and non-motor vehicles, as well as pedestrians and vehicles, are mixed. This requires that embedded solar-powered luminous road studs not only provide good illumination for motor vehicle drivers, but also for non-motor vehicle drivers and pedestrians. Furthermore, they should be able to transmit different road information based on the different speeds and observation angles of motor vehicle drivers, non-motor vehicle drivers, and pedestrians.

[0005] Furthermore, previously, underground solar-powered road studs were mainly used on ordinary roads, limiting their application scenarios. However, roads are now increasingly subdivided according to their functions, such as urban roads, tourist roads, and slow-moving roads, often requiring more lighting modes to meet the demands of functional diversification.

[0006] Existing buried solar-powered illuminated road studs have limited functionality and target users. They are not effective at illuminating non-motorized vehicle drivers and pedestrians, and they lack the ability to convey different road information to motorized vehicle drivers, non-motorized vehicle drivers, and pedestrians. In particular, they are no longer able to meet the new demands of the times for buried solar-powered illuminated road studs in complex traffic areas such as intersections.

[0007] Furthermore, the vehicle's autonomous driving system places higher demands on road studs, and the fatal flaws of existing road studs can lead to misjudgments by the vehicle's vision recognition system, causing serious safety hazards.

[0008] Therefore, ensuring the luminous effect of buried solar-powered road studs, so that their luminous observation angle (elevation angle) is complete and there are no blind spots for pedestrians, in order to adapt to the increasing trend of mixed pedestrian and vehicle traffic, and to facilitate intelligent driving, intelligent control and multi-functional lighting, has become an urgent task. Utility Model Content

[0009] Addressing the limitations of existing buried solar-powered LED lighting road studs, this invention proposes a novel edge-enhanced light distribution type buried solar-powered LED lighting road stud, achieving enhanced illumination in all four directions (front, back, left, and right) without blind spots (e.g., ...). Figure 3 As shown), the light emission angle in the forward and backward (moving) directions is omnidirectional (up to 180°). Figure 1 (As shown in Figure 4), it can not only improve the luminous performance of existing road studs, but also add luminous functions to achieve multi-mode luminous illumination. It can be applied to roads of all levels and complex application scenarios, and is also conducive to vehicle-mounted vision recognition systems. It can better adapt to intelligent driving and intelligent control to meet the ever-evolving traffic demands. It has very high practical value and application prospects.

[0010] This utility model, while meeting national standards and industry specifications, combines material forming processes, luminescence, and optics to comprehensively consider and fully utilize the limited size resources of solar road studs, maximizing the area ratio of the solar photovoltaic panel to ensure sufficient electricity for its luminous performance. Through optical matching of the luminescent optical structure and assembly structure, it breaks through the conventional design of existing solar road studs. A rectangular photovoltaic device with a shorter front-to-back length and a longer left-to-right length is set below the middle of the transparent top of the transparent optical shell. LED high-beam light source groups are set along the width direction near the front and back sides of the photovoltaic device. Edge LED brightening light distribution light source groups are respectively set between the front end (emission direction) of the LED high-beam light source group and the inner wall of the transparent enclosure in front of it, and between the left and right ends of the photovoltaic and the inner walls of the corresponding left and right transparent enclosures (i.e., near the front and rear ends and left and right ends of the road stud), forming a front-to-back, left-to-right edge distribution... Light can enhance the brightness and illumination effect, and the edge LED brightness enhancement and light distribution light source group and the LED high beam light source group can form a matching edge LED near light source group and center LED high light source group. Furthermore, it can be combined with the four corner edge light distribution, that is, to further enhance the light distribution effect on the basis of front, rear, left and right edge light distribution, which can maximize the visible light-emitting area and form more light-emitting patterns. In particular, the edge LED brightness enhancement and light distribution light source group at the front of the LED high beam light source group has more advantages. By matching the location, angle, brightness and color of the LED main light source with the edge LED brightness enhancement and light distribution light source group, the overall light-emitting effect is improved. The LED near light source group can make the light-emitting area larger for close observation, which is beneficial to the observation of non-motorized vehicle drivers and pedestrians. The LED high light source group can make the long-range light-emitting distance longer, which is beneficial to the observation of motor vehicle drivers. Furthermore, the edge LED brightness enhancement and light distribution light source group can dynamically emit light and outline the edge contour of the road studs.

[0011] The LED high beam light source group and the edge LED brightening and light distribution light source group can be controlled separately through the control and drive circuit to realize a variety of light-emitting modes and effects, such as dual-group dual control, multi-group multi-control, and dual-color or multi-color switching of light emission. It can also be connected to wireless devices to realize wireless controlled light emission function and intelligent network control function. By switching the light emission mode, different traffic information can be transmitted to motor vehicles, non-motor vehicles and pedestrians respectively, which greatly expands the application scenarios and application areas of road studs.

[0118] Example 1

[0119] A type of edge-enhanced light distribution buried solar LED lighting road stud includes a transparent optical plastic shell (110), an inner support body (120), a curing body (130) with encapsulant, an LED high beam light source group (140), a front and rear edge LED brightening and light distribution light source group one (150-1), a left and right edge LED brightening and light distribution light source group two (150-2), a four corner edge LED brightening and light distribution light source group three (150-3), a photovoltaic device (160) containing a power generation cell, an energy storage element (170), a control and drive circuit (180), a bottom cover (190), a protective ring cover (1100-1), a protective lower shell (1100-2), fasteners (1110), and shock-absorbing rubber pads (1140). Figure 2-8 As shown.

[0120] The transparent optical plastic shell (110) is a transparent PC injection molded cavity shell with a downward opening formed by a transparent top (110d) and a transparent enclosure (110b) that is integral with it and extends downward. The transparent top (110d) is a partially missing circle that is recessed around its outer periphery by fixing screw holes (6 in total, front, back and 4 corners) when viewed from above. The transparent top (110d) has a relatively low pressing part around it that forms a stepped structure.

[0121] The inner support body (120) is a transparent injection-molded support layer with convex and concave lamp grooves on its edges, adapted to the inner cavity structure of the transparent optical shell (110). It is fixed in the accommodating cavity (110q) by a positioning structure and adhesive, and an air layer is formed between the top of the inner support body (120) and the inner top wall of the transparent optical shell (110). Alternatively, a PCB circuit board layer can be used as the inner support body (120) to form an air layer.

[0122] The transparent optical plastic shell (110) has a rectangular photovoltaic device (160) with a shorter front-to-back length and a longer left-to-right length on the inner support body (120) below the middle section extending from the transparent top (110d) to the left and right ends of the inner top wall of the transparent top (110d) of the photovoltaic device (160). Along the width direction, near the inner top wall of the transparent top (110d) of the photovoltaic device (160), there are two sets of concave main light-emitting slots (140c) that are adapted to the LED high-beam light source group (140) and emit light in the front-to-back direction, with a left-to-right length shorter than that of the photovoltaic device (160). The main light-emitting slot (140c) has an incident light surface and an emitted light surface corresponding to the front-to-back light emission of the LED high-beam light source group (140). The main light-emitting slot (140c) is composed of three separate light-emitting slots divided by two separators (140g), and is rectangular in top view and has an inverted V-shaped vertical cross-section. The light-emitting slot has optical structures on its front and rear emitting surfaces that facilitate the LED high beam light source group (140) to emit light at the required assembly angle, including but not limited to light refraction structures, focusing structures, light angle deflection structures, and light beam upward shifting structures. The inner support body (120) below the main light-emitting slot (140c) has three Lamp-encapsulated straw hat-shaped F5-F8 LED beads with focusing lenses fixed to corresponding positions via slots and adhesive, respectively, serving as the LED high beam light source group (140). Each straw hat-shaped LED bead is fixed in its corresponding light-emitting slot. This forms a light emission channel where the main beam of the LED high beam light source group (140) matches the optical structure on the main light-emitting slot (140c) and emits light through its emitting surface with a central principal optical axis elevation angle (θ4) between 0° and 20° (inclusive) and an emission range angle (α4) between 20° and 45°.

[0123] The inner top wall above the edge between the front end of the main light-emitting slot (140c) and the transparent enclosure (110b) in front of it is also provided with a concave front and rear side light-emitting slot one (150c-1) adapted to the front and rear side LED brightness enhancement and light distribution light source group one (150-1). The inner top wall above the edge between the left and right ends of the photovoltaic device (160) and the transparent enclosure (110b) on the left and right sides is also provided with a concave left and right side light-emitting slot two (150c-2) adapted to the left and right side LED brightness enhancement and light distribution light source group two (150-2). Furthermore, the inner top wall above the left and right sides of the main light-emitting slot (140c) is also provided with a concave four-corner side light-emitting slot three (150c-3) adapted to the four-corner side LED brightness enhancement and light distribution light source group three (150-3).

[0124] The front and rear side light-emitting slot 1 (150c-1) and the left and right side light-emitting slot 2 (150c-2) are light-emitting slots with an arc-like shape and an inverted U-shaped vertical cross-section. The four corner side light-emitting slot 3 (150c-3) is a light-emitting slot with a triangle-like shape and an inverted U-shaped vertical cross-section. The front and rear side light-emitting slot 1 (150c-1), the left and right side light-emitting slot 2 (150c-2), and the four corner side light-emitting slot 3 (150c-3) have light-diffusing grids (150k) on their emission surfaces, which are conducive to the light-distribution light source group (150) of the side LEDs emitting light with a large emission range angle. The transparent inner support body (120) below it is connected to the upper and lower recessed lamp slots of the corresponding areas by a slot and an adhesive. The 18 SMD-packaged 2835 surface-mount LEDs fixedly soldered to the lamp board and facing upwards serve as the first LED brightness enhancement and light distribution light source group (150-1) (4 LEDs at the front and rear), the second LED brightness enhancement and light distribution light source group (150-2) (3 LEDs at the left and right), and the third LED brightness enhancement and light distribution light source group (150-3) (1 LED at each of the four corners). The first LED brightness enhancement and light distribution light source group (150-1) at the front and rear and the third LED brightness enhancement and light distribution light source group (150-3) at the four corners form front-to-back light distribution and left-to-right light distribution with the LED high beam light source group (140), respectively. The second LED brightness enhancement and light distribution light source group (150-2) at the left and right can compensate for the light output in the left and right directions.

[0125] Alternatively, a recessed front and rear edge light-emitting groove (150c-1) adapted to the front and rear edge LED brightness enhancement and light distribution light source group one (150-1) can be provided only on the inner top wall corresponding to the edge between the front end of the main light-emitting groove (140c) and the transparent enclosure (110b) in front of it. Furthermore, a recessed four-corner edge light-emitting groove three (150c-3) adapted to the four-corner edge LED brightness enhancement and light distribution light source group three (150-3) can be provided on the inner top wall corresponding to the left and right sides of the main light-emitting groove (140c). The front and rear edge light-emitting groove one (150c-1) and the four-corner edge light-emitting groove three (150c-3) are described above. The transparent inner support body (120) below 50c-3) corresponds to the upper and lower recessed lamp slots of the corresponding area. Twelve SMD-packaged 2835 surface-mount LED beads are fixed to the upper surface of the lamp plate via slots and adhesive. These serve as the front and rear edge LED brightness enhancement and light distribution light source group one (150-1) (4 beads each at the front and rear) and the four corner edge LED brightness enhancement and light distribution light source group three (150-3) (1 bead at each corner). The front and rear edge LED brightness enhancement and light distribution light source group one (150-1) and the four corner edge LED brightness enhancement and light distribution light source group three (150-3) together with the LED high beam light source group (140) form front and rear light distribution and left and right light distribution.

[0126] Alternatively, a recessed front and rear side light-emitting groove (150c-1) can be provided on the inner top wall above the edge between the front end of the main light-emitting groove (140c) and the transparent enclosure (110b) in front of it, which is adapted to the first LED brightness enhancement and light distribution light source group (150-1) on the front and rear sides. Furthermore, a recessed left and right side light-emitting groove (150c-2) can be provided on the inner top wall above the edge between the left and right ends of the photovoltaic device (160) and the transparent enclosure (110b) on the left and right sides, which is adapted to the second LED brightness enhancement and light distribution light source group (150-2) on the left and right sides. The front and rear side light-emitting groove (150c-1) The transparent inner support body (120) below the left and right side light-emitting slots (150c-2) and the corresponding area of ​​the upper and lower recessed lamp slots are fixed to the lamp board with 14 SMD packaged 2835 surface mount LEDs facing upwards by the slots and adhesive respectively. The lamp board serves as the front and rear side LED brightness enhancement and light distribution light source group one (150-1) (4 in each direction) and the left and right side LED brightness enhancement and light distribution light source group two (150-2) (6 in each direction). The side LED brightness enhancement and light distribution light source group (150) and the LED high beam light source group (140) form front and rear light distribution. The left and right side LED brightness enhancement and light distribution light source group two (150-2) can compensate for the light output in the left and right directions.

[0127] Alternatively, the transparent optical plastic shell (110) can be flipped over, and a liquid mixture of long-afterglow luminescent powder and transparent epoxy resin can be dripped into the front and rear side light-emitting grooves (150c-1) and the left and right side light-emitting grooves (150c-2), and then leveled and cured to form a long-afterglow luminescent body (1130). Figure 9-11 As shown, the second LED brightness enhancement light source group (150-2) on the left and right sides below uses blue 2835 LED beads that are easy to excite long-afterglow light emitters. These beads are controlled to emit light periodically with a certain period and duty cycle (e.g., T=1s, λ=10%), which in turn excites the long-afterglow light emitter (1130) to emit light. Especially when the power is insufficient, the long-afterglow light emitter (1130) can be excited by external light to emit afterglow light, which improves the lighting reliability of the road studs.

[0128] The LED high beam light source group (140), the front and rear side LED brightness enhancement and light distribution light source group one (150-1), the left and right side LED brightness enhancement and light distribution light source group two (150-2), the four corner side LED brightness enhancement and light distribution light source group three (150-3), the photovoltaic device (160), the energy storage element (170) and the control and drive circuit (180) are connected by circuit. The energy storage element (170) and the control and drive circuit (180) are respectively embedded below the inner support body (120). The bottom cover (190) with the glue filling hole is combined with the bottom of the transparent optical plastic shell (110) by ultrasonic heat sealing structure (preferably ultrasonic heat sealing weld). Then, the two-component epoxy resin is poured from its glue filling hole, leveled and cured to serve as the waterproof and insulating encapsulation inner liner structure of the encapsulation glue cured molding body (130).

[0129] A shock-absorbing rubber pad (1140) is placed at the bottom of the accommodating cavity of the lower protective shell (1100-2). The aforementioned waterproof and insulating encapsulated inner liner structure is then fitted into the accommodating cavity of the lower protective shell (1100-2). A portion of the bottom surface of the protective ring cover (1100-1), which has six fixing screw holes corresponding to the circular missing area of ​​the transparent top (110d), is pressed onto the stepped inner ring of the lower protective shell (1100-2), and another portion is pressed onto the transparent optical plastic shell. On the pressing part of (110), a fastening screw is screwed into the fixing screw hole to serve as a fastening structural component (1110). Then, silicone sealant is dripped on the top of the fastening screw and cured to seal it, thus locking the waterproof and insulating encapsulated inner liner structure into the protective outer shell formed by the assembly of the protective ring cover (1100-1) and the protective lower shell (1100-2). Alternatively, a mixture of long-afterglow luminescent powder and silicone sealant can be dripped on the top of the fastening screw and leveled and cured to form a long-afterglow luminescent material.

[0130] The control and drive circuit (180) can control the light emission modes of the LED high beam light source group (140) and the front and rear side LED brightening and light distribution light source group one (150-1), the left and right side LED brightening and light distribution light source group two (150-2), and the four corner side LED brightening and light distribution light source group three (150-3), respectively, to achieve various control and light emission effects such as dual-group dual control, multi-group multi-control, and dual-color or multi-color switching of light emission color. It can also be connected to wireless devices to realize wireless controlled light emission function and intelligent network control function, forming an intelligent light-emitting road stud. It can transmit different traffic information to motor vehicles, non-motor vehicles and pedestrians through the switching of light emission modes.

[0131] When this utility model's buried solar-powered luminous road stud is installed, the part below the buried baseline [the height of the upper edge of the protective lower shell] is buried in the ground (road surface). It has both a bidirectional LED luminous effect with the LED high beam light source group shooting forward and backward at a small angle of elevation, and an LED luminous effect with the edge LED brightening and distribution light source group shooting upward at a wide angle. The edge LED brightening and distribution light source group can compensate for the brightness and angle of the LED main light source, thus enhancing the luminous effect. This allows for a larger luminous area for close-range observation, which is beneficial for non-motorized vehicle drivers and pedestrians. The long-range luminous distance is also longer, which is beneficial for motorized vehicle drivers. It can adapt to the increasing trend of mixed pedestrian and vehicle roads and is conducive to intelligent control and multi-functional luminescence, with good social and economic benefits.

[0132] Example 2

[0133] A type of edge-positioned, buried solar-powered, light-emitting plastic-shell road stud includes a transparent optical plastic shell (210), an inner support body (220), a curing encapsulant body (230), an LED high-beam light source group (240), a front and rear edge LED brightening and light-distributing light source group one (250-1), a left and right edge LED brightening and light-distributing light source group two (250-2), a four-corner edge LED brightening and light-distributing light source group three (250-3), a photovoltaic device (260) containing a power-generating element, an energy storage element (270), a control and drive circuit (280), and a bottom cover (290). Figure 12-16 Show.

[0134] The transparent optical plastic shell (210) is a transparent PC injection molded cavity shell with a downward opening formed by a transparent top (210d) and a transparent enclosure (210b) that is integral with it and extends downward. The transparent top (210d) is circular when viewed from above.

[0135] The inner support body (220) is a transparent injection-molded support layer with convex and concave lamp grooves on the edge that is adapted to the inner cavity structure of the transparent optical plastic shell (210). It is fixed in the accommodating cavity (210q) by positioning structure and adhesive, and an air layer is formed between the top of the inner support body (220) and the inner top wall of the transparent optical plastic shell (210).

[0136] The transparent optical plastic shell (210) has a rectangular photovoltaic device (260) with a shorter front-to-back length and a longer left-to-right length on the inner support body (220) below the middle section extending from the transparent top (210d) to the left and right ends of the transparent top (210d). Along the width direction, near the inner top wall of the transparent top (210d) of the photovoltaic device (260), there are two sets of concave main light-emitting slots (240c) that are adapted to the LED high-beam light source group (240) and emit light in the front-to-back direction, with a left-to-right length shorter than that of the photovoltaic device (260). The main light-emitting slots (240c) have light-incident surfaces and light-emitting surfaces corresponding to the front-to-back light emission of the LED high-beam light source group (240). The main light-emitting slots (240c) are composed of two separate light-emitting slots divided by a separator (240g), and are rectangular in top view and have an inverted V-shaped vertical cross-section. The light slot has optical structures on its front and rear emitting surfaces that facilitate the LED high beam light source group (240) to emit light at the required assembly angle, including but not limited to light refraction structures, focusing structures, light angle deflection structures, and light beam upward shifting structures. In the corresponding area of ​​the inner support body (220) below the main light slot (240c), four Lamp-encapsulated straw hat-shaped lamp plates with focusing lenses (F5-F8) are fixed and welded together via slots and adhesive, serving as the LED high beam light source group (240). Two straw hat-shaped LED beads are fixed in pairs within their respective secondary light slots. This forms a light emission channel where the main beam of the LED high beam light source group (240) matches the optical structure on the main light slot (240c), and then emits light through its emitting surface with a central principal optical axis elevation angle (θ4) between 0° and 25° (inclusive) and an emission range angle (α4) between 15° and 45°.

[0137] The inner top wall above the edge between the front end of the main light-emitting slot (240c) and the transparent enclosure (210b) in front of it is also provided with a concave front and rear side light-emitting slot one (250c-1) adapted to the front and rear side LED brightness enhancement and light distribution light source group one (250-1). The inner top wall above the edge between the left and right ends of the photovoltaic device (260) and the transparent enclosure (210b) on the left and right sides is also provided with a concave left and right side light-emitting slot two (250c-2) adapted to the left and right side LED brightness enhancement and light distribution light source group two (250-2). Furthermore, the inner top wall above the left and right sides of the main light-emitting slot (240c) is also provided with a concave four-corner side light-emitting slot three (250c-3) adapted to the four-corner side LED brightness enhancement and light distribution light source group three (250-3).

[0138] The front and rear side light-emitting slot 1 (250c-1) and the left and right side light-emitting slot 2 (250c-2) are light-emitting slots with an arc-like shape and an inverted U-shaped vertical cross-section. The four corner side light-emitting slot 3 (250c-3) is a light-emitting slot with a triangle-like shape and an inverted U-shaped vertical cross-section. The front and rear side light-emitting slot 1 (250c-1), the left and right side light-emitting slot 2 (250c-2), and the four corner side light-emitting slot 3 (250c-3) have light-diffusing grids (250k) on their emission surfaces that facilitate the emission of light from the edge LED brightness distribution light source group (250) with a large emission range angle. The transparent inner support body (220) below it has corresponding slots and adhesives below the upper and lower convex and concave lamp slots in the corresponding areas. The 18 SMD-packaged 2835 surface-mount LEDs fixedly soldered to the lamp board and facing upwards serve as the first LED brightness enhancement and light distribution light source group (250-1) (4 LEDs at the front and rear), the second LED brightness enhancement and light distribution light source group (250-2) (3 LEDs at the left and right), and the third LED brightness enhancement and light distribution light source group (250-3) (1 LED at each of the four corners). The first LED brightness enhancement and light distribution light source group (250-1) at the front and rear and the third LED brightness enhancement and light distribution light source group (250-3) at the four corners form front-to-back light distribution and left-to-right light distribution with the LED high beam light source group (240), respectively. The second LED brightness enhancement and light distribution light source group (250-2) at the left and right can compensate for the light output in the left and right directions.

[0139] The LED high beam light source group (240), the front and rear LED brightness enhancement and light distribution light source group one (250-1), the left and right LED brightness enhancement and light distribution light source group two (250-2), the four corner LED brightness enhancement and light distribution light source group three (250-3), the photovoltaic device (260), the energy storage element (270), and the control and drive circuit (280) are connected by circuits. The energy storage element (270) and the control and drive circuit (280) are respectively buried under the inner support body (220). The bottom cover (290) with the glue filling hole is combined with the bottom of the transparent optical plastic shell (210) by ultrasonic heat sealing structure (preferably ultrasonic heat sealing weld). Then, two-component epoxy resin is poured from its glue filling hole, leveled and cured to act as encapsulant and cured into a molded body (230), forming a plastic shell buried solar cell. Illuminated track spikes

[0140] The control and drive circuit (280) can control the light emission modes of the LED high beam light source group (240) and the front and rear side LED brightening and light distribution light source group one (250-1), the left and right side LED brightening and light distribution light source group two (250-2), and the four corner side LED brightening and light distribution light source group three (250-3), respectively, to achieve various control and light emission effects such as dual-group dual control, multi-group multi-control, and dual-color or multi-color switching of light emission color. It can also be connected to wireless devices to realize wireless controlled light emission function and intelligent network control function. By switching the light emission mode, different traffic information is transmitted to motor vehicles, non-motor vehicles and pedestrians respectively.

[0141] Alternatively, a reflective layer can be coated on the outer wall of the transparent enclosure (210b) of the transparent optical plastic shell (210) to reflect and enhance brightness. The LED brightness enhancement and light distribution light source group 1 (250-1) at the front and rear sides, the LED brightness enhancement and light distribution light source group 2 (250-2) at the left and right sides, or the LED brightness enhancement and light distribution light source group 3 (250-3) at the four corners can emit light through multiple reflections within the accommodating cavity (210q) of the transparent optical plastic shell (210) to achieve a superimposed brightness enhancement effect.

[0142] This utility model of an in-ground solar-powered luminous road stud can be installed in the ground (road surface) as a plastic-shell road stud combined with mounting adhesive, or after surface protection treatment or post-processing, it can be installed in the ground (road surface) as a plastic-shell road stud combined with mounting adhesive. It has both the bidirectional LED light emission effect of the LED high beam light source group facing forward and backward at a small angle of elevation, and the LED light emission effect of the edge LED brightening and distribution light source group facing upward at a wide angle. The edge LED brightening and distribution light source group can compensate for the brightness and angle of the LED main light source, thus enhancing the light emission effect. This allows for a larger luminous area for close-range observation, which is beneficial for non-motorized vehicle drivers and pedestrians. The long-range luminous distance is also longer, which is beneficial for motorized vehicle drivers. It can adapt to the increasing trend of mixed pedestrian and vehicle roads, and is conducive to intelligent control and multi-functional lighting, with good social and economic benefits.

[0144] A type of edge-enhanced light distribution buried solar LED lighting road stud includes a transparent optical plastic shell (310), an inner support body (320), a curing encapsulant body (330), an LED high beam light source group (340), a front and rear edge LED brightening and light distribution light source group one (350-1), a left and right edge LED brightening and light distribution light source group two (350-2), a four corner edge LED brightening and light distribution light source group three (350-3), a photovoltaic device containing a power generation cell (360), an energy storage element (370), a control and drive circuit (380), a bottom cover (390), a protective ring cover (3100-1), a protective lower shell (3100-2), fasteners (3110), and shock-absorbing rubber pads (3140). Figure 17-20 As shown.

[0145] The transparent optical plastic shell (310) is a transparent PC injection molded cavity shell with a downward opening formed by a transparent top (310d) and a transparent enclosure (310b) that is integral with it and extends downward. The transparent top (310d) is a circular shape that is partially missing from the outside when viewed from above, with the outer periphery occupied by fixing screw holes (6 in total, front, back and 4 corners). The transparent top (310d) has a relatively low pressing part around it that forms a stepped structure.

[0146] The inner support body (320) is a transparent injection-molded support layer with convex and concave lamp grooves on the edge that is adapted to the inner cavity structure of the transparent optical plastic shell (310). It is fixed in the accommodating cavity (310q) by positioning structure and adhesive, and an air layer is formed between the top of the inner support body (320) and the inner top wall of the transparent optical plastic shell (310).

[0147] The transparent optical shell (310) has a rectangular photovoltaic device (360) with a shorter front-to-back length and a longer left-to-right length on the inner support body (320) below the middle section extending from the transparent top (310d) to the left and right ends of the transparent top (310d). Along the width direction, near the inner top wall of the transparent top (310d) of the photovoltaic device (360), there are two sets of concave main light-emitting slots (340c) that are adapted to the LED high-beam light source group (340) and emit light in the front-to-back direction, with a left-to-right length shorter than that of the photovoltaic device (360). The main light-emitting slots (340c) have light-incident surfaces and light-emitting surfaces corresponding to the front-to-back light emission of the LED high-beam light source group (340). The main light-emitting slots (340c) are composed of two separate light-emitting slots divided by a separator (340g), and are rectangular in top view and have an inverted V-shaped vertical cross-section. The light slot has optical structures on its front and rear emitting surfaces that facilitate the LED high beam light source group (340) to emit light at the required assembly angle, including but not limited to light refraction structures, focusing structures, light angle deflection structures, and light beam upward shifting structures. In the corresponding area of ​​the inner support body (320) below the main light slot (340c), four Lamp-encapsulated straw hat-shaped lamp plates with focusing lenses (F5-F8) are fixed and welded to the front and rear via slots and adhesive, respectively, serving as the LED high beam light source group (340). Two straw hat-shaped LED beads are fixed as a group in the corresponding secondary light slots. The whole structure forms a light emission channel where the main beam of the LED high beam light source group (340) matches the optical structure on the main light slot (340c), and then emits light through its emitting surface with a central principal optical axis elevation angle (θ4) between 0° and 30° (inclusive) and an emission range angle (α4) between 20° and 45°.

[0148] The inner top wall above the edge between the front end of the main light-emitting slot (340c) and the transparent enclosure (310b) in front of it is also provided with a concave front and rear side light-emitting slot 1 (350c-1) adapted to the front and rear side LED brightness enhancement and light distribution light source group 1 (350-1). The inner top wall above the edge between the left and right ends of the photovoltaic device (360) and the transparent enclosure (310b) on the left and right sides is also provided with a concave left and right side light-emitting slot 2 (350c-2) adapted to the left and right side LED brightness enhancement and light distribution light source group 2 (350-2). Furthermore, the inner top wall above the left and right sides of the main light-emitting slot (340c) is also provided with a concave four-corner side light-emitting slot 3 (350c-3) adapted to the four-corner side LED brightness enhancement and light distribution light source group 3 (350-3).

[0149] The front and rear side light-emitting slot 1 (350c-1) and the left and right side light-emitting slot 2 (350c-2) are light-emitting slots with an arc-like shape and an inverted U-shaped vertical cross-section. The four corner side light-emitting slot 3 (350c-3) is a light-emitting slot with a triangle-like shape and an inverted U-shaped vertical cross-section. The front and rear side light-emitting slot 1 (350c-1), the left and right side light-emitting slot 2 (350c-2), and the four corner side light-emitting slot 3 (350c-3) have light-diffusing grids (350k) on their emission surfaces that facilitate the emission of light from the LED light source group (350) at the edges with a large emission range angle. The transparent inner support body (320) below it has corresponding slots and adhesives below the convex and concave lamp slots in the corresponding areas. The 18 SMD-packaged 2835 surface-mount LEDs fixedly soldered to the lamp board and facing upwards serve as the first LED brightness enhancement and light distribution light source group (350-1) (4 LEDs at the front and rear), the second LED brightness enhancement and light distribution light source group (350-2) (3 LEDs at the left and right), and the third LED brightness enhancement and light distribution light source group (350-3) (1 LED at each of the four corners). The first LED brightness enhancement and light distribution light source group (350-1) at the front and rear and the third LED brightness enhancement and light distribution light source group (350-3) at the four corners form front-to-back light distribution and left-to-right light distribution with the LED high beam light source group (340), respectively. The second LED brightness enhancement and light distribution light source group (350-2) at the left and right can compensate for the light output in the left and right directions.

[0150] The transparent optical plastic shell (310) is flipped over, and a liquid mixture of long-afterglow luminescent powder and transparent epoxy resin is dripped into the front and rear side light-emitting groove one (350c-1) and the left and right side light-emitting groove two (350c-2), and then leveled and cured to form a long-afterglow luminescent body (3130). The left and right side LED brightness enhancement and light distribution light source group two (350-2) below it uses blue 2835 LED beads that are easy to excite the long-afterglow luminescent body to emit light periodically with a certain period and duty cycle (such as T=1s, λ=10%), which excites the long-afterglow luminescent body (3130) to emit light. Especially when the power is insufficient, the long-afterglow luminescent body (3130) can emit afterglow light by being excited by external light, which improves the lighting guarantee of the road studs.

[0151] The LED high beam light source group (340), the front and rear side LED brightness enhancement and light distribution light source group one (350-1), the left and right side LED brightness enhancement and light distribution light source group two (350-2), the four corner side LED brightness enhancement and light distribution light source group three (350-3), the photovoltaic device (360), the energy storage element (370) and the control and drive circuit (380) are connected by circuit. The energy storage element (370) and the control and drive circuit (380) are respectively embedded in the lower part of the inner support body (320). The bottom cover (390) with the glue filling hole is combined with the bottom of the transparent optical plastic shell (310) by ultrasonic heat sealing structure (preferably ultrasonic heat sealing weld). Then, the waterproof and insulating encapsulation inner liner structure is formed by pouring and leveling the two-component epoxy resin from its glue filling hole and curing it to act as the encapsulation glue cured molding body (330).

[0152] A shock-absorbing rubber pad (3140) is placed at the bottom of the accommodating cavity of the lower protective shell (3100-2). The aforementioned waterproof and insulating encapsulated inner liner structure is then fitted into the accommodating cavity of the lower protective shell (3100-2). A portion of the bottom surface of the protective ring cover (3100-1), which has six fixing screw holes corresponding to the circular missing area of ​​the transparent top (310d), is pressed onto the stepped inner ring of the lower protective shell (3100-2), and another portion is pressed onto the pressing part of the transparent optical plastic shell (310). Fastening screws are screwed into the fixing screw holes to serve as fastening structural components (3110). Silicone glue is then dripped onto the fastening screws and cured to seal them, thus locking the waterproof and insulating encapsulated inner liner structure into the protective outer shell formed by assembling the protective ring cover (3100-1) and the lower protective shell (3100-2).

[0153] The control and drive circuit (380) can control the light emission modes of the LED high beam light source group (340) and the front and rear side LED brightening and light distribution light source group one (350-1), the left and right side LED brightening and light distribution light source group two (350-2), and the four corner side LED brightening and light distribution light source group three (350-3), respectively, to achieve various control and light emission effects such as dual-group dual control, multi-group multi-control, and dual-color or multi-color switching of light emission color. It can also be connected to wireless devices to realize wireless controlled light emission function and intelligent network control function. By switching the light emission mode, different traffic information is transmitted to motor vehicles, non-motor vehicles and pedestrians respectively.

The transparent top (410d) has a relatively low pressing part around it that forms a stepped structure.

[0157] The inner support body (420) is a transparent injection-molded support layer that is adapted to the inner cavity structure of the transparent optical plastic shell (410), has convex and concave lamp grooves on the front and rear edges, and through holes on the left and right edges. It is fixed in the accommodating cavity (410q) by positioning structure and adhesive, and an air layer is formed between the top of the inner support body (420) and the inner top wall of the transparent optical plastic shell (410).

The main light-emitting slot (440c) has an incident light surface and an exit light surface corresponding to the front-to-back light emission of the LED high-beam light source group (440). The main light-emitting slot (440c) is composed of two separate light-emitting slots divided by a separator (440g), and is rectangular in top view and has an inverted V-shaped vertical cross-section. The light slot has optical structures on its front and rear emitting surfaces that facilitate the LED high beam light source group (440) to emit light at the required assembly angle, including but not limited to light refraction structures, focusing structures, light angle deflection structures, and light beam upward shifting structures. In the corresponding area of ​​the inner support body (420) below the main light slot (440c), four Lamp-encapsulated straw hat-shaped lamp plates with focusing lenses (F5-F8) are fixed and welded together via slots and adhesive, serving as the LED high beam light source group (440). Two straw hat-shaped LED beads are fixed in pairs within their respective secondary light slots. This forms a light emission channel where the main beam of the LED high beam light source group (440) matches the optical structure on the main light slot (440c), and then emits light through its emitting surface with a central principal optical axis elevation angle (θ4) between 0° and 30° (inclusive) and an emission range angle (α4) between 20° and 45°.

The transparent inner support body (420) below it corresponds to the upper and lower convex areas. Below the recessed light trough, 12 upward-facing SMD-packaged 2835 surface-mount LEDs are fixed to the light board via slots and adhesive, respectively serving as the front and rear edge LED brightness enhancement and light distribution light source group one (450-1) (4 LEDs at the front and rear) and the four corner edge LED brightness enhancement and light distribution light source group three (450-3) (1 LED at each corner). The front and rear edge LED brightness enhancement and light distribution light source group one (450-1) and the four corner edge LED brightness enhancement and light distribution light source group three (450-3) respectively form front-rear light distribution and left-right light distribution with the LED high beam light source group (440).

The vertical (standing) lamp panel passes through the through hole of the transparent injection-molded bracket layer (420) and is fixed by the slot.

The energy storage element (470) and the control and drive circuit (480) are respectively embedded under the inner support body (420). The bottom cover (490) with the glue filling hole is combined with the bottom of the transparent optical plastic shell (410) by ultrasonic heat sealing structure (preferably ultrasonic heat sealing weld). Then, the waterproof and insulating encapsulation inner liner structure is formed by pouring and leveling the two-component epoxy resin from its glue filling hole and curing it to act as the encapsulation glue cured molding body (430).

[0163] A shock-absorbing rubber pad (4140) is placed at the bottom of the accommodating cavity of the lower protective shell (4100-2). The aforementioned waterproof and insulating encapsulated inner liner structure is then fitted into the accommodating cavity of the lower protective shell (4100-2). A portion of the bottom surface of the protective ring cover (4100-1), which has eight fixing screw holes corresponding to the circular missing area of ​​the transparent top (410d), is pressed onto the stepped inner ring of the lower protective shell (4100-2), and another portion is pressed onto the pressing part of the transparent optical plastic shell (410). Fastening screws are screwed into the fixing screw holes to serve as fastening structural components (4110). Silicone glue is then dripped onto the fastening screws and cured to seal them, thus locking the waterproof and insulating encapsulated inner liner structure into the protective outer shell formed by assembling the protective ring cover (4100-1) and the lower protective shell (4100-2).

[0164] The control and drive circuit (480) can control the light emission modes of the LED high beam light source group (440) and the front and rear side LED brightening and light distribution light source group one (450-1), the left and right side LED brightening and light distribution light source group two (450-2), and the four corner LED brightening and light distribution light source group three (450-3) respectively, realizing various control and light emission effects such as dual-group dual control, multi-group multi-control, and dual-color or multi-color switching of light emission color. It can also be connected to wireless devices to realize wireless controlled light emission function and intelligent network control function. [The LED high beam light source group (440) and the front and rear side LED brightening and light distribution light source group one (450-1), the left and right side LED brightening and light distribution light source group two (450-2), and the four corner LED brightening and light distribution light source group three (450-3) can each use LEDs with different light emission colors and emit light with their own different cycles and duty cycles.] By switching the light emission mode, different traffic information is transmitted to motor vehicles, non-motor vehicles, and pedestrians respectively.

[0165] When installing this type of buried solar-powered luminous road stud, the portion below the buried baseline (the height of the upper edge of the protective lower shell) is buried in the ground (road surface). It provides both bidirectional LED illumination with the LED high-beam light source group projecting light forward and backward at small angles, and LED illumination with the front, rear, and four corner LED enhancement and distribution light source groups projecting light upwards at wide angles, as well as LED illumination with the left and right corner LED enhancement and distribution light source groups projecting light in opposite directions. The corner LED enhancement and distribution light source groups can provide brightness and angle compensation for the main LED light source. It enhances the brightness and light emission, allowing for a larger luminous area for close-range observation, which is beneficial for non-motorized vehicle drivers and pedestrians. The long-range luminous distance is also greater, which is beneficial for motorized vehicle drivers. Furthermore, the LED brightening and light distribution light source groups discretely surrounding the edge of the transparent optical plastic shell of the road stud can highlight and outline part or the entire outline of the road stud when they emit light. It can adapt to the increasing trend of mixed pedestrian and vehicle roads, and is especially suitable for installation on the road surface in places such as intersections, crossroads, and pedestrian crossings. It also facilitates intelligent control and multi-functional lighting, and has good social and economic benefits.

[0166] Example 5

[0167] A coated protective plastic shell edge-distributed ground-mounted solar-powered lighting road stud includes a transparent optical plastic shell (510), a composite base shell (520), a coated protective layer (530), a cured encapsulant body (540), an inner support body (550), an LED high-beam light source group (560-1), front and rear edge LED brightening and light distribution light source groups (560-2), left and right edge LED brightening and light distribution light source groups (560-3), a photovoltaic device (570), an energy storage element (580), a control and drive circuit (590), a mirror reflection layer (5100), and a fastening structure (5110). Figure 26-31 As shown.

[0168] The transparent optical plastic shell (510) is a symmetrical PC injection-molded cavity shell with a downward-opening accommodating cavity (510q), formed by a transparent top (510d) and a transparent surrounding wall (510b) integral with it and extending downward.

[0169] The transparent top (510d) has a circular outer contour (viewed from top to bottom). Four protruding supports (510c) are provided at the edge of the transparent top (510d) to prevent sinking during road surface installation. The top surface of the transparent top (510d) has anti-slip protrusions (510p).

[0170] The transparent optical shell (510) has a rectangular photovoltaic device (570) with a shorter front-to-back length and a longer left-to-right length on the inner support body (550) below the middle section extending from the transparent top (510d) to the left and right ends of the transparent top (510d). Along the width direction, near the inner top wall of the transparent top (510d) of the photovoltaic device (570), there are two sets of concave main light-emitting slots (560c-1) that are adapted to the LED high-beam light source group (560-1) and emit light in the front-to-back direction, with a left-to-right length shorter than that of the photovoltaic device (570). The main light-emitting slot (540c) has an incident light surface and an emitting light surface corresponding to the front-to-back light emission of the LED high-beam light source group (540). The main light-emitting slot (560c-1) is composed of three separate light-emitting slots divided by two separators, and is rectangular in top view with an inverted V-shaped vertical cross-section. The front and rear exit surfaces (560m) are inclined. The light exit slot has optical structures, including but not limited to light refraction structures, focusing structures, light angle deflection structures, and light beam upward shifting structures, which facilitate the LED high beam light source group (560-1) to emit light at the required assembly angle. On the inner support body (550) below the main light exit slot (560c-1), three Lamp-encapsulated straw hat-shaped F5 to F8 LED beads with focusing lenses are fixed and welded to the corresponding positions by slots and adhesives, respectively, to serve as the LED high beam light source group (560-1). Each straw hat-shaped LED bead is fixed in the corresponding light exit slot. The whole structure forms a light emission channel where the main beam of the LED high beam light source group (560-1) is matched with the optical structure on the main light exit slot (560c-1) and emitted light through its exit surface with a central principal optical axis elevation angle between 0° and 20° (inclusive) and an emission range angle between 20° and 45°.

[0171] The inner top wall above the edge between the front end of the main light-emitting slot (560c-1) and the transparent enclosure (510b) in front of it is also provided with a concave front and rear side light-emitting slot (560c-2) adapted to the front and rear side light distribution light source (560-2). The inner top wall above the edge between the left and right ends of the photovoltaic device (570) and the transparent enclosure (510b) on the left and right sides of it is also provided with a concave left and right side light-emitting slot (560c-3) adapted to the left and right side light distribution light source (560-3).

[0172] The front and rear side light-emitting slots (560c-2) and the left and right side light-emitting slots (560c-3) are light-emitting slots with an arc-shaped or semi-arc shape and an inverted U-shaped vertical cross-section. The emission surfaces of the front and rear side light-emitting slots (560c-2) and the left and right side light-emitting slots (560c-3) can be equipped with light-diffusing grids that facilitate the emission of light from the front and rear side light distribution sources (560-2) and the left and right side light distribution sources (560-3) with a large emission range angle. The inner support body (550) below them... The 12 upward-emitting SMD-packaged 2835 surface-mount LEDs, fixed to the lamp board below the convex and concave lamp slots in the corresponding areas via slots and adhesive, serve as the front and rear edge light distribution light sources (560-2) (4 at the front and 4 at the rear) and the left and right edge light distribution light sources (560-3) (2 at the left and 3 at the left and right) respectively. These front and rear edge light distribution light sources (560-2) and left and right edge light distribution light sources (560-3), together with the LED high beam light source group (560-1), form the positional, angular, and brightness light distribution.

[0173] The edges of the transparent top (510d) on both sides transition from the inside out and from high to low with a curved surface to their upper edge, which serves as the buried reference line.

[0174] The outer surface of the transparent enclosure (510b) has a second outwardly protruding vertical support (510z-2). Below the protruding support (510c), the transparent enclosure (510b) has a corresponding concave pile-type vertical support structure (510s-1). The pile-type vertical support structure (510s-1) has a through fixing hole (5110k). The bottom inner circumference of the transparent enclosure (510b) has a recessed ring-shaped fitting structure (510q). Inside the ring-shaped fitting structure (510q), there are ring-shaped hot-melt ribs of matching shape, serving as a composite structure (510h).

[0175] An aluminum-plated layer is vapor-deposited on the outer surface of the transparent enclosure (510b) to serve as a mirror-reflective layer (5100). Then, a mixture of liquid (including oil-based or water-based) acrylic resin coating (or liquid acrylic resin coating) and silica particles between 500 and 50 mesh is sprayed onto the outer surface of the transparent enclosure (510b) and thermo-cured to form a rough, sand-finished coating layer. This creates an inner and outer composite protective coating layer (530), which not only enhances reflectivity and brightness but also strengthens the bond between the transparent optical shell (510) and the mounting adhesive, preventing loosening and detachment.

[0176] The inner support body (550) is a transparent injection-molded support layer with convex and concave lamp grooves on its edges, which is adapted to the inner cavity structure of the transparent optical plastic shell (510). It is fixed in the accommodating cavity (510q) by a stepped positioning structure (510d) and adhesive, and an air layer is formed between the top of the inner support body (550) and the inner top wall of the transparent optical plastic shell (510).

[0177] The LED high beam light source group (560-1), front and rear side light distribution light sources (560-2), left and right side light distribution light sources (560-3), photovoltaic device (570), energy storage element (580), and control and drive circuit (590) are connected by circuitry. The energy storage element (580) and control and drive circuit (590) are respectively embedded below the inner support body (550), and the above components are then fixed in the transparent optical plastic shell (510) with two-component epoxy resin.

[0178] The composite bottom shell (520) is a bottom cover type injection molded bottom shell with a glue-filling hole (520k) and a concave spoke-shaped recess (520j) at the bottom (which can make the bottom of the composite shell more firmly bonded to the mounting glue and prevent it from rotating), and through fixing holes (5120k) at the four corners. The edge of the composite bottom shell (520) has an upwardly convex ring-shaped fitting structure (520q), and the edge of the composite bottom shell (520) has an upwardly convex arc-shaped fitting structure (520q). Between the two, there is a welding groove corresponding to the composite structure (510h) at the bottom of the transparent enclosure (510b) to serve as the composite structure (520h). The second fitting structure (520q) of the bottom shell (520) is fitted onto the fitting structure (510q) at the bottom of the transparent enclosure (510b), so that the composite bottom shell (520) surrounds the bottom periphery of the transparent enclosure (510b). The composite shell is formed by hot-melt bonding of the first composite structure (510h) and the second composite structure (520h) with the transparent optical plastic shell (510). Then, two-component epoxy resin is poured from its potting hole (520k) and leveled and cured to act as encapsulant to cure and form a pressure-resistant and waterproof encapsulation structure (540). Finally, fastening screws are used as fastening structures (51110) to combine the transparent optical plastic shell (510) and the composite bottom shell (520) a second time.

[0179] This utility model relates to a coated protective plastic shell edge-distributed buried solar-powered road stud. During installation, the portion below the ground reference line (the height of the upper edge of the protective lower shell) is buried in the ground (road surface). It provides both bidirectional LED illumination with a small-angle upward-facing and backward-facing LED high-beam light source group, and upward-facing wide-angle LED illumination with front and rear edge-distributed LED brightening light source groups, as well as left and right edge-distributed LED brightening light source groups emitting light in opposite directions. The edge-distributed LED brightening light source groups can compensate for the brightness and angle of the main LED light source, enhancing its brightness. This results in a larger illuminated area for close-range observation, benefiting non-motorized vehicle drivers and pedestrians, and a longer viewing distance for long-range observation, benefiting motorized vehicle drivers. Furthermore, the edge-distributed LED brightening light source groups, discretely surrounding the edge of the transparent optical plastic shell of the road stud, can highlight or outline part or all of the stud's contours, making it suitable for mixed pedestrian and vehicular traffic. With the increasing development of roads, these buried solar-powered road studs are particularly suitable for installation at intersections, crossroads, and pedestrian crossings. They facilitate intelligent control and multi-functional illumination, and meet national and industry standards for waterproofing and pressure resistance. The protective coating on the outer surface of their composite shell allows them to be used with various adhesives and expanding cement, both solvent-based and solvent-free, as well as on asphalt and cement surfaces. This protects the plastic shell from the solvents in the adhesive and the chemicals in the asphalt, solving the critical problem of short lifespan for plastic-shell road studs. They are especially suitable for transparent PC shells, and the bonding between the plastic-shell stud and the adhesive is stronger, preventing loosening and detachment. Compared to existing buried solar-powered road studs with metal protective shells, they have lower manufacturing and installation costs and even better reflective properties, offering higher cost-effectiveness and better application prospects.

[0180] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. All modifications, variations, combinations, additions, equivalent substitutions, etc., made within the spirit and principles of the present utility model, or the application of the present technology to related and similar technical fields, should be included within the protection scope of the present utility model.
