Description

Technical Field

[0001] The utility model specifically relates to a self-luminous road stud with solar energy, belonging to the technical field of road studs. Background Art

[0002] Solar road studs are a type of traffic raised road sign that uses solar panels as charging components, batteries or capacitors as energy storage components, and uses LEDs to illuminate or passively reflect. It is a traffic safety facility that is mainly installed in the middle of the road markings or the middle of the double yellow line, and reminds drivers to drive in the lane through its retro-reflective performance. Its visual effect is better than that of ordinary road studs. In addition to being used on highways, it can also be used in parks, courtyards, plywood, aisles and other places to play a role in lighting and warning. In actual use, these solar road studs usually use a stroboscopic method to illuminate the LEDs, alternating between emitting and not emitting (extinguishing) in consideration of the limitation of energy storage. If there are no other luminous components at the moment when the LEDs are extinguished, people will suddenly fall into darkness and produce a completely black state. To avoid this situation, high-frequency flash is mostly used, which can easily cause visual fatigue and emotional irritability, which is not conducive to traffic safety. The constant light mode is a better working state, but it has higher requirements for battery energy storage. Therefore, how to design a self-luminous road stud with solar energy has become a problem that needs to be solved. Summary of the invention

[0003] In view of the problems existing in the prior art, the utility model provides a self-luminous road stud with solar energy, in order to solve the problem of reducing the flicker and prolonging the luminous time without increasing energy consumption.

[0004] The technical solution of the utility model is as follows:

[0005] A self-luminous road stud with solar energy comprises a base, wherein the base comprises an upper quadrangular pyramid and a lower column, a first cavity is opened at the center of the upper surface of the quadrangular pyramid, a second cavity is arranged in the column, and the first cavity is connected with the second cavity; a storage battery is placed in the second cavity, and a control circuit board, a photovoltaic cell panel, a light-transmitting luminous module, a light-homogenizing sheet, and a translucent injection layer containing fluorescent luminous material are placed in the first cavity from bottom to top; the storage battery, the photovoltaic cell panel, and the light-transmitting luminous module are all electrically connected to the control circuit board.

[0006] Furthermore, fixing holes are respectively provided on a pair of opposite side surfaces of the quadrangular pyramid.

[0007] Furthermore, grooves are respectively provided on another pair of opposite sides of the tetrahedral pyramid, and reflective sheets or side-light emitting components are installed in the grooves. The side-light emitting components are electrically connected to the control circuit board.

[0008] Furthermore, the quadrangular pyramid and the column are an integral casting structure.

[0009] Furthermore, the first cavity is a square cavity.

[0010] Furthermore, the second cavity is a cylindrical cavity, and the battery is a cylindrical battery.

[0011] Beneficial effects: The utility model seals the electrical components below through a translucent injection layer containing fluorescent luminescent material, and has good waterproof and wear-resistant effects. During the day, sunlight can penetrate downward through the injection layer, pass through the light-emitting module after passing through the light-distributing sheet to reach the photovoltaic panel to start generating electricity, and the generated electricity is used to charge the battery through the control board. At night, the battery intermittently supplies power to the light-emitting module and the side light-emitting component through the control board, and the light-emitting module intermittently emits light, and the emitted light passes through the light-distributing sheet and then enters the injection layer, a part of which is transmitted from the injection layer, and the other part is absorbed by the fluorescent material in the injection layer. After absorbing the light, the fluorescent material will emit fluorescence outward, and the fluorescence can be maintained for a certain period of time, and gradually decays during this period of time to achieve a light storage effect. When the fluorescence decays to a certain extent, the next light emission of the light-emitting module begins, and such a cycle can achieve continuous lighting of the road studs and reduce the stroboscopic frequency, thereby reducing energy consumption.

DETAILED DESCRIPTION

[0017] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0018] like Figure 1-4As shown, a self-luminous road stud with solar energy includes a base 1, and the base 1 includes an upper tetrahedral pyramid 11 and a lower column 12. The tetrahedral pyramid 11 and the column 12 are an integral casting structure, for example, an integral cast aluminum structure. The tetrahedral pyramid 11 is a regular tetrahedral pyramid, with a small upper end face and a large lower end face, and has a certain thickness. The column 12 is connected directly below the center of the lower end face, vertically downward, and the column 12 has a certain length. An anti-slip and anti-rotation structure can also be provided on the outer surface of the column. When in use, the column can be inserted into the mounting hole on the ground, so that the bottom surface of the tetrahedral pyramid is bonded, contacted and fixed to the ground; fixing holes 113 can also be provided on a pair of opposite side surfaces of the tetrahedral pyramid, and screws or bolts can be installed in the fixing holes 113 to fix them to the ground, so as to ensure the installation and fixing effect of the base and the ground.

[0019] A first cavity is provided at the center of the upper surface of the tetrahedral pyramid 11, and the first cavity may be a square cavity 111. A second cavity is provided in the column 12, and the second cavity is a cylindrical cavity 121. The first cavity is connected to the second cavity. A cylindrical rechargeable battery 2 is placed in the second cavity, and may be, for example, a 18650 lithium-ion battery. A control circuit board 3, a photovoltaic panel 4, a light-transmitting luminous module 5, a light-homogenizing sheet 6, and a translucent injection layer 7 containing fluorescent luminescent materials are placed in the first cavity from bottom to top; wherein the control circuit board controls the charging and discharging of the battery, the discharge time and frequency, etc., the photovoltaic panel can convert light energy into electrical energy and store it in the battery, the light-transmitting luminescent module has good light transmission performance and can emit light under the power supply of the battery, the light-homogenizing sheet can homogenize the light passing through itself, and the translucent injection layer containing fluorescent luminescent materials is in a flowing state before curing, for example, it can be a transparent epoxy resin, and fluorescent materials such as strontium aluminate and other fluorescent powders are added therein, and after being evenly stirred, it can be cured into an injection layer, and the injection layer is first irradiated by a light source and its fluorescent material is in an excited state, and when the external light source disappears, the electrons of the fluorescent material will jump from the excited state to the ground state, thereby emitting fluorescence, and the emitted fluorescence will last for a certain period of time and gradually decay, so that the injection layer has a certain light storage capacity. A groove 112 is provided on the other opposite side surfaces of the tetrahedron, and a side light emitting component 8 or a reflector is installed in the groove 112. The battery, photovoltaic panel, light-transmitting light emitting module, and side light emitting component are all electrically connected to the control circuit board. Since the battery is designed to be stored in the column of the base, the thickness of the tetrahedron can be reduced, and the column can be inserted into the mounting hole on the ground, so the whole layout is more reasonable. The side light emitting components or reflectors on both sides can be the same color, or different colors to distinguish different driving directions.

[0020] The manufacturing process of the light-storage solar road stud is as follows: first, an aluminum base 1 is obtained by a casting process, and then the side light-emitting components 8 are respectively glued and installed in the two grooves 112 on the side of the quadrangular pyramid 11, and the lead of the side light-emitting component 8 is introduced into the square cavity 111 in advance, and then a cylindrical battery 2 is placed in the cylindrical cavity 121 of the base, and then a control circuit board 3, a photovoltaic panel 4, a light-transmitting luminous module 5, etc. are placed in the square cavity in sequence. These electrical components can be electrically connected in advance, or they can be placed while being welded and connected, and the lead of the side light-emitting component is electrically connected to the control circuit board. When all electrical components are connected, a light-dispersing sheet 6 is covered on the top of the light-transmitting luminous module 5, and finally a glue containing fluorescent material is poured on the light-dispersing sheet until the glue completely fills the square cavity. After the glue is solidified, the production of the light-storage solar road stud is completed.

[0021] The above-mentioned solar road stud can be installed in the middle of the double yellow line of the road. The column of the base can be inserted into the hole in the ground and injected with glue. At the same time, the bottom surface of the four-sided pyramid and the ground are bonded with glue, and then the base is fixed to the ground with expansion bolts passing through the fixing holes of the base. Pay attention to the direction during installation so that the side light-emitting components on both sides face the direction of the two-way oncoming lane. During the day when the sunshine is good, the sunlight can penetrate the injection layer and penetrate downward. After being uniformly distributed by the light-distributing sheet, the light passes through the light-emitting module and reaches the photovoltaic panel to start generating electricity. The generated electricity is used to charge the battery through the control panel. At night, the battery intermittently supplies power to the light-emitting module and the side light-emitting component through the control panel. The light-emitting module emits light intermittently. The light emitted penetrates the light-distributing sheet and enters the injection layer. Part of the light is transmitted from the injection layer, and the other part is absorbed by the fluorescent material in the injection layer. After absorbing the light, the fluorescent material will emit fluorescence outward, and the fluorescence can be maintained for a certain period of time and gradually decay during this period of time. When the fluorescence decays to a certain extent, the next light emission of the light-emitting module begins. In the interval between the two light-emitting modules, the injection layer consistently emits fluorescence with a certain brightness. In this way, the light storage capacity of the road stud is realized, that is, continuous light emission. At the same time, it can also reduce the light stroboscopic frequency of the LED light-emitting component, reduce energy consumption, extend the service life, and is conducive to traffic safety.
