DETAILED DESCRIPTION

[0029] The following is a further description of the specific implementation of the present invention in conjunction with the accompanying drawings and embodiments. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and cannot be used to limit the protection scope of the present invention.

[0030] “Side”, “surface”, “circumference” and “outer surface” are referenced to the normal use state of the photovoltaic lighting device for curbs and are only for the convenience of describing the present invention and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as a limitation on the present invention.

[0031] The terms "first", "second", etc. are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, a feature defined as "first", "second", etc. may explicitly or implicitly include one or more of the features. In the description of the invention of the utility model, unless otherwise specified, the meaning of "plurality" is two or more.

[0032] like Figures 1 to 4 As shown, the photovoltaic lighting device for curb disclosed by the utility model comprises a base 1, a photovoltaic lighting element 2, a reflective isolation plate 3 and a fixing element (not shown); the base 1 is provided with a supporting plane 10, which has a first side (not marked) and a second side (not marked) opposite to each other along a first direction; the photovoltaic lighting element 2 is provided on the supporting plane 10; the fixing element is used to fix the base 1 to the curb, and the first direction and the second direction are perpendicular to each other. When installed and used, the first direction is the horizontal direction, and the second direction is the plumb bob direction.

[0033] The reflective isolation plate 3 is arranged on the first side, and the second side faces the road surface; or the reflective isolation plate 3 is arranged on the second side, and the first side faces the road surface. The reflective isolation plate 3 is fixedly connected to the base 1, wherein the reflective isolation plate 3 has a reflective protrusion 30 and a reflective recess 31 arranged in sequence along the second direction, the reflective protrusion 30 is close to the base 1 and protrudes toward its supporting plane 10, and the concave surface of the reflective recess 31 faces the supporting plane 10. The reflective protrusion 30 can reflect sunlight onto the photovoltaic lighting element, so that it absorbs more sufficient sunlight. The reflective recess 31 can reflect the light radiated by the photovoltaic lighting element 2 onto the road surface, enhance the brightness of the light, and effectively prevent the illumination light from scattering around and affecting the sight of drivers and pedestrians.

[0034] like Figure 1~2 As shown, in some embodiments, the base 1 has a first movable base 11 and a second movable base 12 opposite to each other along a first direction, the first movable base 11 and the second movable base 12 are connected in a sleeve, and the two are connected by a first elastic member (not shown). The first movable base 11 and the second movable base 12 each include a first supporting plate 111 and a first fixed baffle 110, the supporting plane 10 is arranged on the outer first supporting plate 111, the first fixed baffle 110 extends in the opposite direction along the second direction, the first fixed baffle 110 and the first supporting plate 111 are connected by a first rotating shaft (not marked), and the extension direction of the first rotating shaft is consistent with the length direction of the base 1. The elastic member includes but is not limited to rubber and spring. The first movable base 11 and the second movable base 12 are connected by an elastic member, which is suitable for curbs of different widths and is easy to install and fix. The first movable base 11 and the second movable base 12 are sleeved to improve the support strength. The first fixed baffle plate 110 is connected to the first supporting plate 111 via a rotation axis, so as to be suitable for curbs with top surfaces of different slopes and walls of different flatnesses.

[0035] like Figure 3As shown, in other embodiments, the base 1 has a side movable base 101 opposite to each other along a first direction and a supporting base 13 sandwiched between the side movable base 101, the supporting plane 10 is arranged on the supporting base 13, the side movable base 101 is sleeved with the supporting base 13, and the side movable bases 101 are connected by a second elastic member (not shown). The side movable base 101 includes a second fixed baffle 120 and a second supporting plate 112 extending in opposite directions along the second direction, the second fixed baffle 120 and the second supporting plate 112 are connected by a second rotating shaft (not marked), and the extension direction of the second rotating shaft is consistent with the length direction of the base 1. The setting of the supporting base 13 can flexibly adjust the position on the top surface of the curb, and when the side movable base 101 adjusts the distance between the two along the first direction, the supporting strength of the supporting base 13 changes little and the stability is maintained well.

[0036] Furthermore, an elastic layer 20 is provided on the inner surface of the base 1. The provision of the elastic layer 20 not only prevents the uneven surface of the curb from abrading the surface of the base, but also adjusts the inclination angle of the base and the flatness of the supporting plane, which is beneficial for the photovoltaic lighting component to face the incident direction of sunlight and prevents water from accumulating on the surface of the photovoltaic lighting component. The material of the elastic layer includes natural rubber, synthetic rubber (such as styrene-butadiene rubber (SBR), nitrile rubber (NBR), chloroprene rubber (CR), etc.), thermoplastic elastomer (TPE) (such as thermoplastic polyurethane) and silicone rubber. Among them, silicone rubber has excellent heat resistance and chemical stability.

[0037] In order to further improve the installation stability of the base and facilitate the fixed connection between the photovoltaic lighting element and the supporting plane, the first fixed baffle 110 or the second fixed baffle 120 is provided with a through hole 100 that cooperates with the thread of the fixing element.

[0038] The photovoltaic lighting device 2 includes a shell, a transparent sealing cover and a light strip. The shell is used to accommodate photovoltaic cells, livestock batteries, a controller and a photosensitive sensor. The transparent sealing cover is arranged at the opening of the shell, and the light strip is arranged around the shell. The photosensitive sensor transmits the change of the brightness of the external light to the controller, and the controller plays the function of regulating the battery to supply power to the light strip. Among them, the light strip close to the road illuminates the road, and the light strip far away from the road concentrates and reflects the light on the road through the reflective protrusion 30 and the reflective recessed part 31, thereby improving the brightness of the lighting.

[0039] like Figure 4As shown, the outer surfaces of the transparent sealing cover and the light strip are both provided with an anti-reflection film 4, which includes a substrate layer 40 and a wear-resistant surface layer 41, and an anti-reflection recess 400 is provided at the interface where the substrate layer 40 and the wear-resistant surface layer 41 are connected. The anti-reflection recess 400 can collect and fully absorb sunlight when it enters the photovoltaic lighting element from the outside to the inside; during illumination, the light radiates from the inside to the outside, increasing the brightness of the light and the area of ​​light dispersion. The anti-reflection recess 400 is provided at the interface where the substrate layer 40 and the wear-resistant surface layer 41 are connected, effectively preventing water from accumulating in the anti-reflection recess 400, which causes the problem that the film surface is easily burned by the concentrated light.

[0040] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
