Description

Technical Field

[0001] This invention relates to the field of traffic safety lighting equipment, specifically to a solar-powered brightening and reflective elastic column. Background Technology

[0002] Flexible bollards are typically used as traffic safety equipment, installed at urban intersections, lane dividers, and sidewalks to serve as warnings and signs. They can also be used to divide or separate lanes and guide traffic to ensure road safety.

[0003] Existing resilient bollards typically consist of a bollard and a base. The bollard is covered with reflective film or fixed reflective sheets, and its overall color is often a striking red and white or red and yellow stripe. During the day, the bollard's bright color provides primary warning, while at night, the reflective film or sheets reflect the headlights of oncoming vehicles. However, these reflective bollards are ineffective in low-visibility conditions such as rain or fog, posing a safety hazard.

[0004] Some have proposed installing solar photovoltaic panels on the base of the flexible column and installing warning lights inside the column, such as a traffic warning column with application number 201820818401.1, and a solar-powered luminous reflective flexible column previously published by our company with application number 202520819645.1. The basic principle of this approach is to install light-emitting elements inside a transparent, semi-transparent, or colored translucent flexible column, using solar photovoltaic panels mounted on the base to generate electricity, which then drives the light-emitting elements. The light generated by the light-emitting elements is transmitted through the flexible column walls, thus creating an active surface-emitting effect. However, this type of design has the following significant drawbacks:

[0005] 1. The light emitted by the light-emitting element of this type of elastic column must first penetrate the lamp housing, then travel a long distance through the air medium inside the column cavity, and finally reach the column wall and be transmitted out. During this process, the light is scattered and attenuated due to long-distance air propagation, and its intensity is inversely proportional to the square of the propagation distance L (E∝1 / L). 2 Furthermore, when light passes through the column wall, the light transmission attenuation rate of the transparent column wall can reach more than 30%. If a colored transparent column wall, such as one with fluorescent color, is used, the attenuation rate can reach 50% or even more than 80%, resulting in a significant decrease in the brightness of the active light emission and low light efficiency, which makes it difficult to meet the actual needs. In particular, when the elastic column is installed under streetlights or other high-illuminance environments, or even during the day, its own light emission brightness is easily submerged by ambient light, and the light emission effect is very unsatisfactory, especially during the day when it is completely ineffective.

[0006] Second, when using translucent pillars with colors such as fluorescent colors, although they are more eye-catching during the day, the light filtering effect of the translucent pillars results in a monotonous light emission color, making it difficult to achieve dynamic warning effects with multiple color combinations such as red and blue, red and green. This makes it impossible to provide differentiated visual prompts for different scenarios (such as road construction, traffic diversion, emergency accidents, etc.), limiting its applicability in complex environments and failing to meet users' diverse needs for multifunctional warning signs.

[0007] Third, the transparent, translucent or colored light-transmitting elastic columns of this type are prone to aging and yellowing under long-term exposure to sun and rain, resulting in a continuous decrease in light transmittance and further reduction in luminous brightness.

[0008] Fourth, for existing elastic column products with added light-blocking solid inorganic pigments (such as yellow, red, blue, green, gray, and black solid inorganic pigments), the light emission from the luminescent body suffers severe light decay. For existing black hollow columns and non-hollow foamed (such as PU foam and EVA foam) elastic column products, the existing technical solutions are not applicable because the column walls are almost opaque.

[0009] In summary, existing solar-powered reflective elastic columns still suffer from problems in practical applications, such as insufficient active light emission brightness, easy obscuring of light emission by ambient light in high-illuminance environments such as daytime, monotonous light emission color and limited functionality, and decreased light transmittance due to column aging. These issues make it difficult to meet the demands of modern traffic safety for high visibility, multifunctionality, and long-term stable use, and are becoming a pressing problem to be solved in the industry. Summary of the Invention

[0010] Given the significant defects and application limitations of existing technologies, which cannot meet the needs of current market development, we propose a novel concept of a high-energy-efficiency, high-luminous-efficiency solar-powered, brightening, and reflective elastic column. This invention considers various factors, including the product's molding structure and manufacturing process, its light-emitting and optical principles, visual recognition principles, and numerous constraints imposed by traffic regulations. Through innovative product molding structure design, assembly structure design, optical structure design, and matching LED light source and assembly structure, and especially within its limited space, maximizing the area ratio of solar photovoltaic devices to ensure sufficient power generation and energy storage, the invention optimizes the emission direction, light-emitting angle, and luminous intensity (brightness), thereby achieving maximum luminous efficiency and improving the product's viewing distance and visibility. This product, through the combination of high and low light sources, features high active light emission brightness, strong light emission stability throughout its entire life cycle, and excellent visibility in high-illuminance environments such as daytime and street lighting. Its performance has been greatly improved, not only significantly enhancing the light emission performance of existing products used as luminous warning posts, but also serving as a day and night type luminous signal elastic post to achieve multi-color light emission effects and convey more traffic information, or as an auxiliary lighting elastic post, greatly enhancing its functions and expanding its application areas.

[0011] The innovation of this invention lies in the following: an LED light source is installed near the window area within the base of the elastic column, forming a light-emitting structure between the LED light source and the transparent exposed shell of the light-collecting part within at least one window on the base. After the LED light source emits light, the light is ultimately emitted outward from the transparent exposed shell of the light-collecting part within at least one window on the base, thereby optimizing the optical structure and reducing light energy attenuation. Furthermore, since there is no transmission attenuation through the column wall, the brightness of the emitted light is several times, even tens of times, higher than existing wall-transmitting light-emitting products, resulting in a significant improvement in its luminous performance. It remains clearly visible even under high illumination conditions such as streetlights and during the day.

[0012] Meanwhile, this light-emitting path avoids the filtering effect of the column wall color, allowing the first LED light source to use LED beads with a different dominant wavelength than the column wall color. In addition, other LED light sources use LED beads with a dominant wavelength that matches the column wall color (e.g., if the column wall is fluorescent yellow, this LED light source uses yellow LED beads). Through control and driving circuits, synchronous or alternating flashing light modes of the two can be achieved, thereby forming a dynamic warning effect of multiple colors such as red and blue, red and green. This can convey richer traffic safety information, and its function is further expanded. It can adapt to various scenarios such as road construction, traffic diversion and emergency accidents, and meet the needs of differentiated visual prompts.

[0013] Meanwhile, since the light emission path of LED light source one is directly emitted through the transparent exposed shell of the light-collecting part inside the window, it is not affected by the yellowing of the column due to aging, ensuring that its luminous brightness is stable throughout its entire life cycle.

[0014] In terms of structural implementation, the transparent lamp housing is made of pressure-resistant transparent hard material. Its light-transmitting part is tightly fitted with the chassis window. The waterproof encapsulation formed by the lamp housing encapsulation body embeds the light-emitting lamp base. The assembly structure of different soft and hard materials is optimized to increase the fine strength between the two. It has excellent waterproof, dustproof and pressure and impact resistance performance and can adapt to complex and harsh outdoor use environments.

[0015] The main advantage of this design is:

[0016] Firstly, the brightness of the active light emission is significantly improved through the design of its optical structure. By shortening the optical path length of the LED light source, the attenuation of light during transmission through the column wall is effectively avoided, resulting in a light output brightness that is several times or even tens of times higher than that of traditional designs. Even in high-illuminance environments such as daytime or street lighting, it can still maintain clear visibility, thereby enhancing its recognizability.

[0017] Secondly, by matching the light-emitting angle of its LED light source, it can be adjusted to suit different road installation scenarios and different viewing distance requirements, ensuring that road users in different locations (motor vehicle drivers, non-motor vehicle drivers and pedestrians, etc.) can clearly observe the luminous warning signal, thus improving the environmental adaptability of the product.

[0018] Third, by matching the color of its LED light source, a multi-color dynamic warning function can be realized, presenting a multi-color synchronous or alternating flashing effect such as red and blue, red and green, etc., which can convey richer traffic safety information, thereby increasing its functionality and expanding its application range, and can meet the differentiated visual prompting needs of different scenarios such as road construction, traffic diversion, and emergency accidents.

[0019] Fourth, it has strong luminous stability. The light output path of the LED light source is not affected by the yellowing of the column due to aging, ensuring stable and reliable luminous brightness throughout its entire life cycle. Even if its elastic column is damaged, it will not affect the luminous effect of its low-position chassis.

[0020] Fifth, since its light-emitting body emits light from the window in its base, the light emission is not physically restricted by the column wall. Therefore, it can be used with elastic columns containing light-shielding solid inorganic pigments, black hollow columns, and non-hollow foamed products (such as PU foam and EVA foam), thus expanding the application range of existing solar luminous reflective elastic columns.

[0021] Sixth, it has excellent structural durability. In particular, the existing solar-powered elastic pillars have defects in their assembly and fixing structure between the light-emitting embedded base and the chassis, which are easily dislodged by vehicles due to the difference in the hardness of the materials, thus affecting the service life. The product of this invention adopts a pressure-resistant transparent hard material and a waterproof encapsulation structure, which has good waterproof, dustproof, pressure-resistant and impact-resistant performance, can adapt to complex and harsh outdoor use environments, and extend the service life of the product.

[0022] The specific embodiment of the present invention is as follows: a solar-powered brightening and reflective elastic column, comprising an upright part (1a) (whose shape, structure, size, height, etc. can be designed as needed) and a base part (1b) connected to its root and expanding outward from top to bottom (from high to low) to form an elastic column (1), and a waterproof encapsulated light-emitting embedded base (2), wherein the base part (1b) and the light-emitting embedded base (2) are assembled to form a solar-powered brightening and reflective elastic column.

[0023] The column part (1a) of the elastic column (1) is an elastic column structure with the function of automatically restoring itself after being deformed by external force. It is provided with a retroreflector (7) (the type, shape, size, installation position, installation method, etc. of the retroreflector can be designed as needed). The central part of the base part (1b) of the elastic column (1) is provided with a cavity, and the outer expansion area is provided with a through-type (open) window (1b-1).

[0024] The transparent lamp housing (2a) is a rigid transparent lamp housing with pressure resistance. Its central part is raised upward to form an internal cavity shell (2a-2) that matches the structure (including size and shape) of the cavity of the chassis part (1b) (its shape, structure, size, height, etc. can be designed as needed). The internal cavity shell (2a-2) has a downward-opening receiving cavity (2a-2q) below it. The periphery of the internal cavity shell (2a-2) is connected to a plurality of upward-protruding exposed cavity shells (2a-1) that match the structure of the window (1b-1) of the chassis part (1b). The exposed cavity shells (2a-1) are provided with a... There is a downward-opening receiving cavity (2a-1c). A connecting part (2a-3) is provided between the inner cavity shell (2a-2) and the exposed cavity shell (2a-1) (the shape, structure, size, and height can be designed as needed, and a wire passage groove can be provided). A downward-opening wire passage groove (2a-3c) is provided below the connecting part (2a-3) (the structure and depth can be designed as needed, and the cross-section is preferably similar to an inverted U-shape). The transparent lamp shell (2a) forms a relatively low base plate part (2a-4) (a relatively low base shell) in the part other than the exposed cavity shell (2a-1) and the inner cavity shell (2a-2).

[0025] The transparent lamp housing (2a) contains an LED light source (3-1) whose main beam of light energy and / or its corresponding maximum light intensity direction ultimately shines out through the transparent exposed surface of the exposed cavity housing (2a-1) (i.e., the main function of the LED light source is to ensure that light is emitted outward through the exposed cavity housing (2a-1), a photovoltaic device (4), an energy storage element (5), and a control and drive circuit (6). The photovoltaic power generation panel of the photovoltaic device (4) is located in the receiving cavity (2a-1c) of the exposed cavity housing (2a-1), and is connected to the LED light source (3-1). The energy storage element (5) is connected to the control and drive circuit (6) and is encapsulated in the transparent lamp housing (2a) by the lamp housing package (2b) at the bottom of the transparent lamp housing (2a) to form a waterproof encapsulated light-emitting embedded base (2). The light-emitting embedded base (2) is embedded into the base portion (1b) of the elastic column (1) from bottom to top and is assembled with the elastic column (1) by the assembly fixing structure (8) (which can be a combination structure (preferably a fitting structure and / or fasteners) or / or a composite structure (preferably a hot melt composite structure or an adhesive composite structure)).

[0026] The bottom (bottom surface) of the light-emitting embedded base (2) and the bottom (bottom surface) of the chassis (1b) are combined to form an integral support structure for the bottom (bottom surface) of the solar-powered brightening and reflective elastic column. The built-in cavity shell (2a-2) in the center of the transparent lamp shell (2a) is embedded in the root of the column (1a) of the elastic column (1). The bottom part of the elastic column (1) is pressed onto the bottom plate (2a-4) and the connecting part (2a-3) of the transparent lamp shell (2a) (e.g., Figure 22 As shown), the exposed cavity shell (2a-1) is embedded in the window (1b-1) of the chassis (1b) and exposed. The LED light source (3-1) and the transparent lamp shell (2a) are matched in the molding structure, assembly structure and optical structure to form the main beam of the LED light source (3-1) emitting most of the light energy (luminous flux) or / and its corresponding maximum light intensity direction (also called the main light intensity direction) finally pass through the transparent exposed shell (also called the exposed transparent light guide layer, which is both the light-collecting part and the light-emitting part. Light collection refers to collecting external light sources to enable solar photovoltaic devices to generate electricity) of the exposed cavity shell (2a-1) and emit light outward at a certain light-emitting angle (including the light-emitting main axis direction and the light-emitting range angle) and light-emitting brightness.

[0027] Furthermore, the column part (1a) is a transparent, semi-transparent, or colored light-transmitting elastic hollow column structure with an internal cavity and a through hole at the top. The cavity of the column part (1a) is connected to the cavity of the chassis part (1b). The transparent lamp housing (2a) contains an LED light source one (3-1) whose main beam of most of its light energy and / or its corresponding maximum light intensity direction is ultimately emitted outward through the transparent exposed surface of the exposed cavity housing part (2a-1). The accommodating cavity (2a-2q) of the inner cavity housing part (2a-2) also contains an LED light source two (3-2) whose main light energy is emitted into the internal cavity of the column part (1a). (That is, the main function of the LED light source two is to ensure that the light is emitted into the cavity of the column and makes the light source more transparent.) The column part (1a) emits light from the cylindrical surface. The structure of the second LED light source (3-2) and the inner cavity shell part (2a-2) are matched to form a light-emitting structure including but not limited to matching light intensity distribution. The light emitted by the second LED light source (3-2) is projected through the air medium in the hollow cavity of the column part (1a) onto the inner wall of the cavity wall (1a-3) of the column part (1a), and then emitted outward from the outer wall of the cavity wall (1a-3) of the column part (1a). This can form a light-emitting structure in which the exposed cavity shell part (2a-1) emits light with relatively high brightness and the column part (1a) emits light with relatively low brightness (the light-emitting brightness of the transparent exposed shell of the exposed cavity shell part (2a-1) is higher than the light-emitting brightness of the cylindrical surface of the column part (1a).

[0028] Furthermore, the LED light source one (3-1) is assembled within the accommodating cavity (2a-1c), and an assembly structure including but not limited to light intensity distribution matching is formed between the LED light source one (3-1) and the transparent exposed shell of the exposed cavity shell (2a-1).

The light guide structure may be an injection-molded structure in the area where the connecting part (2a-3) is located, or a wire groove in the connecting part (2a-3). The light guide structure formed by pouring liquid transparent resin and curing after inversion (2a-3c) solves the problem of local structural distortion and shrinkage during injection molding, and can improve its light guiding performance. An assembly structure including but not limited to matching light intensity distribution is formed between the LED light source (3-1) and the light guide structure. The exposed cavity shell (2a-1) of the transparent lamp housing (2a) is provided with optical structures (2a-8) including but not limited to focusing, reflection, refraction, and light diffusion. The light emitted by the LED light source (3-1) is matched with the light guide structure and the exposed cavity shell (2a-1) and its optical structures (2a-8) to form an optical emission structure, such as...

Another portion of the LEDs in the first LED light source (3-1) is assembled in a receiving cavity (2a-2q) within the built-in cavity shell (2a-2). A light guide structure is provided on the connecting portion (2a-3) between the LEDs assembled in the receiving cavity (2a-2q) and the transparent exposed surface shell of the exposed cavity shell (2a-1). The light guide structure is a connecting portion (…).

[0162] Detailed Implementation (It should be noted that the embodiments in this article are only illustrated by hollow cylindrical elastic columns, but the scope of protection of the present invention is not limited to this, but can be extended to elastic column designs of other different shapes or structures)

[0163] Example 1

[0164] A solar-powered, brightening, reflective, elastic column consists of a hollow, translucent cylindrical column (1a) and a section that expands outwards from top to bottom into a circle connected to its base (e.g., ...). Figure 6 , Figure 7 The elastic column (1) formed by the integrated base (1b) and the waterproof encapsulated light-emitting embedded base (2) are assembled to form a solar-enhancing, light-emitting, reflective elastic column, as shown. Figures 1-7 As shown.

[0165] The elastic column (1) is a hollow PU elastomer, PE elastomer, or PVC elastomer formed by injection molding. The height of its column part (1a) is between 300mm and 950mm. It has a through hole at the top and multiple horizontally concave annular structures arranged at certain intervals on the upper outer wall. A ring-shaped 3M reflective film is glued inside the concave annular structure to act as a retroreflector (7), which can prevent the retroreflector (7) from peeling off. The lower outer wall has a convex spiral-shaped auxiliary structure (1a-1) that can withstand the pressure of vehicle wheels and increase the rebound force. The side wall near the bottom has a hole (1a-2) to act as a water leakage hole to prevent water accumulation. The outer diameter of the chassis (1b) is between 200mm and 300mm. The outer expansion area of ​​the chassis (1b) is provided with three through-type windows (1b-1) with a set aspect ratio and three through-type circular mounting holes (1b-4). The mounting holes (1b-4) are used to install and fix the solar-powered brightening and reflective elastic column to the road surface or ground. The chassis (1b) is provided with radially radiating reinforcing ribs and tangentially arc-shaped reinforcing ribs, which serve to strengthen the structure and limit movement.

[0166] The transparent lamp housing (2a) is a one-piece molded rigid transparent PC injection-molded lamp housing with pressure resistance. Its central part is raised to form an internal cavity (2a-2). The internal cavity (2a-2) is adapted to the structure of the cavity of the chassis (1b). The side wall of the internal cavity (2a-2) is provided with a drainage groove (2a-6) to prevent water accumulation. The lower part of the internal cavity (2a-2) is provided with a downward-opening receiving cavity (2a-2q). The periphery of the internal cavity (2a-2) is connected with three windows (1b-1) that are adapted to the structure of the chassis (1b). The exposed cavity shell (2a-1) has an upwardly protruding structure with an outwardly inclined top surface. Below the exposed cavity shell (2a-1) is a downward-opening receiving cavity (2a-1c). A connecting portion (2a-3) is provided between the inner cavity shell (2a-2) and each exposed cavity shell (2a-1). The injection-molded structure of the area where the connecting portion (2a-3) is located acts as a light guide structure. The connecting portion (2a-3) is a convex beam with an inverted U-shaped cross-section, extending radially outward along the inner cavity shell (2a-2) and connecting to the exposed cavity shell (2a-1) near the inner cavity shell. In the middle section of one side wall of the cavity shell (2a-2), the base (1b) of the elastic column (1) is provided with an inverted U-shaped notch (1b-2) that matches it. During assembly, the connecting part (2a-3) fits into the notch (1b-2). A downward-opening wire groove (2a-3c) is provided below the connecting part (2a-3). The transparent lamp shell (2a) forms a relatively low base plate (2a-4) in the area other than the exposed cavity shell (2a-1) and the built-in cavity shell (2a-2). The base plate (2a-4) is provided with a groove for connecting the elastic column. The body (1) is equipped with a positioning pile (2a-9). The positioning pile (2a-9) has an assembly hole (2a-7) to form a ring-shaped perforated positioning pile. The base (1b) has a corresponding positioning hole (1b-5). The positioning hole (1b-5) has a non-penetrating assembly hole (1b-6) corresponding to the assembly hole (2a-7). During assembly, the positioning pile (2a-9) is fitted into the positioning hole (1b-5) and fixed by screws passing through the assembly hole (2a-7) from bottom to top and into the assembly hole (1b-6). Figure 7 As shown,

[0167] The solar photovoltaic panel of the photovoltaic device (4) is fixed in the receiving cavity (2a-1c) below the exposed cavity shell (2a-1) at an angle of 30° to 40° by a slot and adhesive. The first LED light source (3-1) consists of multiple SMD packaged surface mount LEDs, which are respectively soldered to the upper left and upper right corners of the circuit board layer where the solar photovoltaic panel of the photovoltaic device (4) is located, so that the first LED light source (3-1) on it emits light at an assembly elevation angle complementary to the tilt angle of the solar photovoltaic panel. The photovoltaic device (4) and the LED light source (3-1) are fixed in the receiving cavity (2a-1c) below the exposed cavity shell (2a-1c) at an angle of 30° to 40° by a slot and adhesive. The first LED light source (3-1) emits light at an assembly elevation angle complementary to the tilt angle of the solar photovoltaic panel. The photovoltaic device (4) and the LED light source (3-1) are fixed in the receiving cavity (2a-1c) below the exposed cavity shell (2a-1c) at an angle of 30° to 40° by a slot and adhesive. The light source (3-1), energy storage element (5), and control and drive circuit (6) are connected by wires passing through wire grooves (2a-3c). After the transparent lamp shell (2a) is inverted, it is potted, leveled and cured with white epoxy or silicone to form a molded encapsulant body (2b) to serve as the lamp shell encapsulation body. The above electronic components are encapsulated in the transparent lamp shell (2a) to form a waterproof encapsulated light-emitting embedded base (2). Alternatively, it can be further encapsulated at its bottom by an ultrasonic hot melt composite structure composite bottom shell. The light-emitting embedded base (2) is embedded from the bottom of the base part (1b) of the elastic column (1) from bottom to top and is assembled with the elastic column (1) as one unit through the assembly fixing structure (8).

[0168] The bottom of the transparent lamp housing (2a) and the bottom of the chassis (1b) combine to form an integral support structure for the bottom of the solar-powered brightening and reflective elastic column. The internal cavity shell (2a-2) in the center of the transparent lamp housing (2a) is embedded in the root of the column (1a) of the elastic column (1). The bottom part of the elastic column (1) is pressed onto the bottom plate (2a-4) and the connecting part (2a-3) of the transparent lamp housing (2a). The exposed cavity shell (2a-1) is embedded in the window (1b-1) of the chassis (1b) and exposed to the outside, accommodating... The light emitted by the LEDs within the cavity (2a-1c) matches the exposed cavity shell (2a-1) to form an optical emission structure. This allows the light emitted by the LEDs to be directly emitted through the transparent outer shell of the exposed cavity shell (2a-1), forming a three-sided dot matrix light source structure. The elevation angle γ of the main light intensity direction emitted by LED light source one (3-1) through the transparent outer shell of the exposed cavity shell (2a-1) is controlled within the range of 10°≤γ≤60°, and the vertical emission range angle β is controlled within the range of 45°≤β≤90°. These settings can be adjusted as needed.

[0169] Furthermore, the LED light source (3-1) also includes another part of LEDs, which are multiple LAMP-packaged straw hat LEDs with focusing heads. These are soldered to the edge of the circular circuit board where the control and drive circuit (6) is located and fixed with the circular circuit board in the accommodating cavity (2a-2q) of the built-in cavity shell (2a-2). This part of the LED emits light at an assembly elevation angle between 0° and 45° (inclusive) towards the light guide structure of the corresponding connecting part (2a-3). The light emitted by the LEDs, together with the light guide structure in the connecting part (2a-3) and the exposed cavity shell (2a-1) and its optical structure (2a-8), forms an optical emission structure. The light emitted by this part of the LEDs is finally emitted outward through the transparent exposed shell of the exposed cavity shell (2a-1) via the light guide structure in the connecting part (2a-3), thus forming a three-sided (e.g., Figure 2 As shown in the diagram, the two LED sections can be configured to fully utilize the exposed surface area of ​​the outer cavity shell (2a-1) while ensuring a sufficiently large installation area for the solar photovoltaic panel. This results in a light-emitting structure with angle-matched brightness superposition or a light-emitting structure with matched light color.

[0170] The elastic column (1) can be a hollow PU elastomer, PE elastomer, or PVC elastomer with inorganic pigments that have high opacity (poor light transmittance but good color durability).

[0171] Furthermore, the elastic column (1) can also be a hollow transparent PU elastomer, PE elastomer, or PVC elastomer with added organic pigments such as fluorescent red or fluorescent yellow. In this case, an LED light source two (3-2) can also be provided. The LED light source two (3-2) is a number of straw hat lamp beads with LAMP packaged with focusing heads, which are vertically or welded at an assembly elevation angle greater than 45° on the circular circuit board where the control and drive circuit (6) is located. The circular circuit board is fixed in the accommodating cavity (2a-2q) below the built-in cavity shell (2a-2) by a slot and adhesive. The second LED light source (3-2) and the transparent top wall of the built-in cavity shell (2a-2) form a light-emitting structure that includes, but is not limited to, matching the light intensity distribution. The light emitted by the second LED light source (3-2) is projected through the air medium in the hollow cavity of the column (1a) onto the inner wall of the cavity wall (1a-3) of the column (1a), and then emitted outward from the outer wall of the cavity wall (1a-3) of the column (1a) to form a relatively high-position, low-brightness column surface light-emitting structure, thereby forming a light-emitting body that combines high and low positions and high and low brightness, and combines point and surface.

[0172] In particular, regarding color configuration, the column part (1a) is a hollow, translucent elastomer in colors such as red, orange, yellow, green, or blue. The second LED light source (3-2) consists of multiple LEDs with a dominant wavelength corresponding to the same or similar color as the PU elastomer of the column part (1a) with a superimposed diffusing agent, or multiple LEDs with a dominant wavelength corresponding to the same or similar color as the PE elastomer of the column part (1a) with a superimposed diffusing agent, or multiple LEDs with a dominant wavelength corresponding to the same or similar color as the PVC elastomer of the column part (1a) with a superimposed diffusing agent. These can serve as signal marker elastic columns emitting multiple colors such as red, orange, yellow, green, or blue. Alternatively, the second LED light source (3-2) can consist of multiple LEDs with a dominant wavelength corresponding to the white light emission color, serving as auxiliary lighting elastic columns.

[0173] The LED light source one (3-1) is a plurality of LED light sources with the same or similar light emission color as the main light emission wavelength corresponding to the emissive color of the elastomer superimposed on the column part (1a). LED light source one (3-1) and LED light source two (3-2) can emit light synchronously or asynchronously with the same color under the control of the control and drive circuit (6), thereby making the overall light emission brightness higher.

[0174] Alternatively, the LED light source one (3-1) may be multiple LED light sources with different emission wavelengths corresponding to the emission colors of the elastomer superimposed with the color of the diffuser of the column part (1a). LED light source one (3-1) and LED light source two (3-2) may emit light synchronously or asynchronously in different colors (two colors or multiple colors) under the control of the control and drive circuit (6), thereby transmitting more traffic information. For example, if the color of the column part (1a) is fluorescent red, LED light source two (3-2) emits red light after being powered on, and LED light source one (3-1) emits blue light after being powered on, then LED light source two (3-2) and LED light source one (3-1) may alternately flash red and blue light under the control of the control and drive circuit (6), thereby transmitting alarm information.

[0175] This invention relates to a solar-powered reflective elastic column that can be installed on the ground in locations requiring warning or guidance, such as roads, parking lots, construction areas, and community entrances, by screws passing through mounting holes in its base. Compared to existing products, its active light emission brightness is significantly improved. Through optical structure matching, it avoids light energy attenuation caused by light transmission through the column wall, resulting in a light emission brightness several times, even tens of times, higher than traditional designs. It remains clearly visible even under high illumination environments such as streetlights and during the day. It achieves multi-color dynamic warning functionality, displaying synchronous or alternating flashing effects of red and blue, red and green, etc., conveying richer traffic safety information and meeting the differentiated visual prompting needs of different scenarios such as road construction, traffic diversion, and emergencies. It exhibits strong luminous stability; the light emission path of the LED light source is unaffected by the yellowing of the column due to aging, ensuring stable and reliable luminous brightness throughout its entire lifespan. With excellent durability, the light-emitting embedded base, made of pressure-resistant transparent rigid material and waterproof encapsulation, has good waterproof, dustproof, pressure-resistant and impact-resistant performance, which can adapt to complex and harsh outdoor environments and extend the product's service life. In particular, one part of its LED light source consists of multiple SMD packaged surface-mount lamp beads, which are respectively soldered to the upper left and upper right corners of the circuit board layer of the solar photovoltaic panel of the photovoltaic device, emitting light from both sides. This avoids the elastic columns arranged on the same side of the road blocking each other's light, ensuring that the warning light effect of each elastic column can be displayed normally. At the same time, it makes full use of the idle space of the solar photovoltaic panel to set up the light source, achieving efficient use of both space and electrical energy.

The flexible circuit board layer is connected to the circuit board layer of the solar photovoltaic panel of the photovoltaic device (4) and is positioned on the upper edge of the solar photovoltaic panel of the photovoltaic device (4) in the single exposed cavity shell (2a-1) corresponding to the front of the elastic column through a positioning slot. The LED beads are vertically arranged and emit light in the horizontal direction. The light emits light at an elevation angle of less than 50°. The photovoltaic device (4), LED light source (3-1), energy storage element (5), and control and drive circuit (6) are connected by wires passing through wire grooves (2a-3c) to form a circuit. After the transparent lamp shell (2a) is inverted, it is potted, leveled and cured with white epoxy or silicone to form a molded encapsulant body (2b) to serve as the lamp shell encapsulation body. The above electronic components are encapsulated in the transparent lamp shell (2a) to form a waterproof encapsulated light-emitting embedded base (2). It can also be further encapsulated at its bottom by an ultrasonic hot melt composite structure composite bottom shell. The light-emitting embedded base (2) is embedded from the bottom of the base part (1b) of the elastic column (1) from bottom to top and is assembled with the elastic column (1) as one unit through the assembly fixing structure (8).

[0181] The bottom of the transparent lamp housing (2a) and the bottom of the chassis (1b) are combined to form an integral support structure for the bottom of the solar-powered brightening and reflective elastic column. The built-in cavity shell (2a-2) in the center of the transparent lamp housing (2a) is embedded in the root of the column (1a) of the elastic column (1). The bottom part of the elastic column (1) is pressed onto the bottom plate (2a-4) and the connecting part (2a-3) of the transparent lamp housing (2a). The exposed cavity shell (2a-1) is embedded in the window (1b-1) of the chassis (1b) and exposed, accommodating the cavity groove (2a-1c). The light emitted by the LED inside matches the exposed cavity shell (2a-1) corresponding to the front of the elastic column to form an optical emission structure. The light emitted by the LED is directly emitted outward through the transparent exposed shell of the exposed cavity shell (2a-1) corresponding to the front of the elastic column, forming a single (front) dot matrix light source emission structure. The elevation angle γ of the main light intensity direction emitted outward through the transparent exposed shell of the exposed cavity shell (2a-1) is controlled at: 10°≤γ≤60°, and the vertical emission range angle β is controlled at: 45°≤β≤90°, which can be set as needed.

[0182] Furthermore, the LED light source (3-1) also includes another part of LEDs, which are multiple LAMP-packaged straw hat LED beads with focusing heads. These are respectively soldered to the edge of the circular circuit board where the control and drive circuit (6) is located and fixed with the circular circuit board in the accommodating cavity (2a-2q) of the built-in cavity shell (2a-2). After being flipped in the through groove (2a-3c) of the connecting part (2a-3), liquid transparent epoxy resin is poured in and cured to form a light guide structure (solving the problem of local structural distortion and shrinkage during injection molding, which can improve its light guiding performance). This part of the LED emits light towards the corresponding connecting part (2a-3) at an assembly elevation angle between 0° and 45°, including 0°. The light emitted by the LED matches the light guide structure in the connecting part (2a-3) and the exposed cavity shell (2a-1) to form an optical emission structure, thereby forming a three-sided structure with emphasis on the front side (e.g., Figure 9 As shown in the diagram, the two LED sections can fully utilize the exposed area of ​​the exposed cavity shell (2a-1) while ensuring a sufficiently large installation area for the solar photovoltaic panel. This allows for the formation of a light-emitting structure on its front side that either has a matching angle, superimposed brightness, or a matching color.

[0183] Alternatively, the LED light source (3-1) can be multiple LAMP-packaged straw hat LED beads with focusing heads, which are respectively soldered to the edge of the circular circuit board where the control and drive circuit (6) is located and fixed in the accommodating cavity (2a-2q) of the built-in cavity shell (2a-2) along with the circular circuit board. After flipping the wire groove (2a-3c) of the connecting part (2a-3), liquid transparent epoxy resin is poured in and cured to form a light guide structure (which solves the problem of local structural distortion and shrinkage during injection molding and can improve its light guiding performance), so that this part of the LED is at 0°~ The LED emits light at an assembly elevation angle between 45° and 0° towards the corresponding connecting part (2a-3). The light emitted by the LED matches the light guide structure in the connecting part (2a-3) and the exposed cavity shell (2a-1) to form an optical emission structure, thereby forming a light-emitting structure that emits light from the light guide structure with relatively high brightness (i.e., there is no need to install SMD packaged chip LEDs in the accommodating cavity (2a-1c), that is, all LED light sources (3-1) are built into the accommodating cavity (2a-2q)). Its structure is relatively simple and the light-emitting effect is basically sufficient.

[0184] The elastic column (1) can be a hollow PU elastomer, PE elastomer, or PVC elastomer with inorganic pigments that have high opacity (poor light transmittance but good color durability).

[0185] Furthermore, the elastic column (1) can also be a hollow transparent PU elastomer, PE elastomer, or PVC elastomer with added organic pigments such as fluorescent red or fluorescent yellow. In this case, an LED light source two (3-2) can also be provided. The LED light source two (3-2) is a number of straw hat lamp beads with LAMP packaged with focusing heads, which are vertically or welded at an assembly elevation angle greater than 45° on the circular circuit board where the control and drive circuit (6) is located. The circular circuit board is fixed in the accommodating cavity (2a-2q) below the built-in cavity shell (2a-2) by a slot and adhesive. The second LED light source (3-2) and the transparent top wall of the built-in cavity shell (2a-2) form a light-emitting structure that includes, but is not limited to, matching the light intensity distribution. The light emitted by the second LED light source (3-2) is projected through the air medium in the hollow cavity of the column (1a) onto the inner wall of the cavity wall (1a-3) of the column (1a), and then emitted outward from the outer wall of the cavity wall (1a-3) of the column (1a) to form a relatively high-position, low-brightness column surface light-emitting structure, thereby forming a light-emitting body that combines high and low positions and high and low brightness, and combines point and surface.

[0186] This invention relates to a solar-powered reflective elastic column that can be installed on the ground in locations requiring warning or guidance, such as roads, parking lots, construction areas, and community entrances, by screws passing through mounting holes in its base. Compared to existing products, its active light emission brightness is significantly improved. Through optical structure matching, it avoids light energy attenuation caused by light transmission through the column wall, resulting in a light emission brightness several times, even tens of times, higher than traditional designs. It remains clearly visible even under high illumination environments such as streetlights and during the day. It achieves multi-color dynamic warning functionality, displaying synchronous or alternating flashing effects of red and blue, red and green, etc., conveying richer traffic safety information and meeting the differentiated visual prompting needs of different scenarios such as road construction, traffic diversion, and emergencies. Furthermore, it exhibits strong luminous stability, with the light emission path of the LED light source unaffected by the column structure. The aging and yellowing effects are mitigated, ensuring stable and reliable luminous brightness throughout the entire lifespan. The structure boasts excellent durability, employing pressure-resistant transparent rigid materials and a waterproof encapsulated light-emitting embedded base, providing excellent waterproof, dustproof, and pressure and impact resistance. This allows it to adapt to complex and harsh outdoor environments, extending product lifespan. Notably, a portion of the LED light source consists of multiple SMD-packaged surface-mount LEDs soldered to the left and right sides of a flexible circuit board layer. This flexible circuit board layer can be flexibly positioned within the exposed cavity, facilitating adjustments to the luminous angle and improving assembly convenience, while also saving space occupied during assembly.

[0191] Alternatively, the bottom plate (2a-4) of the transparent lamp housing (2a) may be provided with a cylindrical positioning post (2a-9) for assembly with the elastic column (1). The positioning post (2a-9) has a cylindrical perforated positioning post with an assembly hole (2a-7). On the base plate (1b), the positioning hole (1b-5) has a through-hole (1b-6) corresponding to the assembly hole (2a-7). During assembly, the positioning post (2a-9) is fitted into the positioning hole (1b-5) and bolts (8-1) are used to pass through the assembly hole (1b-6) and the assembly hole (2a-7) from top to bottom, respectively, and are fixed with nuts (8-2) to form an assembly fixing structure (8) that is integrated into one unit. Figure 20 As shown,

[0192] The solar photovoltaic panel of the photovoltaic device (4) is fixed in the accommodating cavity (2a-1c) below the exposed cavity shell (2a-1) at an angle of 25° to 45° by the slot and adhesive. The LED light source (3-1) is a plurality of SMD packaged chip lamp beads, which are soldered to the solar photovoltaic panel of the photovoltaic device (4) at the upper edge, so that the LED light source (3-1) on it emits light at an assembly elevation angle complementary to the tilt angle of the solar photovoltaic panel. The photovoltaic device (4), the LED light source (3-1), the energy storage element (5) and the control and drive circuit (6) are connected by wires passing through the wire groove (2a-3c) to form a circuit connection. After the transparent lamp shell (2a) is inverted, it is potted, leveled and cured with white epoxy or silicone to form a curing body for the lamp shell encapsulation body (2b). The above electronic components are encapsulated in the transparent lamp shell (2a) to form a waterproof encapsulated light-emitting embedded base (2). Alternatively, it can be further encapsulated at the bottom by an ultrasonic hot melt composite structure composite bottom shell. The light-emitting embedded base (2) is embedded from below the base portion (1b) of the elastic column (1) from bottom to top and is assembled with the elastic column (1) as a whole by the assembly fixing structure (8).

[0193] The bottom of the transparent lamp housing (2a) and the bottom of the chassis (1b) combine to form an integral support structure for the bottom of the solar-powered brightening and reflective elastic column. The internal cavity shell (2a-2) in the center of the transparent lamp housing (2a) is embedded in the root of the column (1a) of the elastic column (1). The bottom part of the elastic column (1) is pressed onto the bottom plate (2a-4) and the connecting part (2a-3) of the transparent lamp housing (2a). The exposed cavity shell (2a-1) is embedded in the window (1b-1) of the chassis (1b) and exposed. The light emitted by LED light source 1 (3-1) is matched with the exposed cavity shell (2a-1) to form an optical emission structure. The light emitted by LED light source 1 (3-1) is emitted outward through the transparent exposed shell of the exposed cavity shell (2a-1) to form a high-brightness dot matrix light source emission structure. The elevation angle γ of the main light intensity direction emitted by LED light source 1 (3-1) through the transparent exposed shell of the exposed cavity shell (2a-1) is controlled at: 10°≤γ≤60°, and the vertical emission range angle β is controlled at: 45°≤β≤120°, which can be set as needed.

[0194] After the LED light source one (3-1) emits light, it ultimately emits high-brightness light outward from the transparent exposed shells (three sides) of the three exposed cavity shells (2a-1), forming a high-brightness three-sided light-emitting structure. Furthermore, the horizontal light emission angle α of the LED light source one (3-1) emitted from the transparent exposed shell of a single exposed cavity shell (2a-1) is controlled within the range of 45°≤α≤90°, or within the range of 120°≤α≤150°, forming an overall 360° horizontal light-emitting structure with no dead angles.

[0195] Alternatively, after the LED light source one (3-1) emits light, it emits high-brightness light from the transparent exposed shell (single-sided) of one of the exposed cavity shells (2a-1) and low-brightness light from the transparent exposed shells (double-sided) of the other two exposed cavity shells (2a-1), forming a three-sided light-emitting structure with one side having higher brightness and the other two sides having lower brightness. The horizontal range angle α of the light emitted by the LED light source one (3-1) from the transparent exposed shell of a single exposed cavity shell (2a-1) is controlled at: 45°≤α≤90°, or the horizontal range angle α of the light emitted by the LED light source one (3-1) from the transparent exposed shell of a single exposed cavity shell (2a-1) is controlled at: 120°≤α≤150°, forming an overall horizontal 360° light-emitting structure with no dead angles, emphasizing single-sided light emission (one (θ=0°) or two (θ>0°) light emission directions).

[0196] The LED light source (3-1) can also be multiple SMD packaged surface-mount LED beads, soldered to the middle area of ​​the solar photovoltaic panel of the photovoltaic device (4). The exposed outer shell (2a-1) directly opposite it has protruding vertical strips on its transparent outer surface, which serve as an optical structure (2a-8). The light emitted by the LED light source (3-1) matches the exposed outer shell (2a-1) and its optical structure (2a-8) to form an optical emission structure, such as... Figure 19 , 20 As shown, the light emitted by LED light source 1 (3-1) is refracted and reflected by the optical structure, causing the main beam emitted from the middle part of the convex vertical strip to be deflected in the horizontal direction (i.e., deflected downwards, so that the elevation angle γ of the main light intensity is reduced), so as to enhance the light emission effect at a long distance. At the same time, the light beam emitted from the side of the convex vertical strip is deflected to both sides, which can increase its light emission range angle, so as to enhance the light emission effect at a short distance.

[0197] LED light source one (3-1) can also be multiple SMD packaged surface mount LEDs, soldered onto the circuit board at an assembly angle between 0° and 45° (inclusive), and fixed in the wire guide groove (2a-3c) of the connecting part (2a-3) by a slot and adhesive. Its light emission direction faces the transparent exposed shell of the exposed cavity shell (2a-1). The light emitted by LED light source one (3-1) matches the exposed cavity shell (2a-1) to form an optical emission structure, such as... Figure 14 , 15 As shown; LED light source one (3-1) can also be multiple LAMP packaged straw hat lamp beads with focusing heads, soldered at an assembly elevation angle between 0° and 50° (inclusive) on the edge of the circular circuit board where the control and drive circuit (6) is located, with its light emission direction facing the transparent exposed shell of the exposed cavity shell (2a-1), and a light guide structure is provided on the connection part (2a-3) between LED light source one (3-1) and the transparent exposed shell of the exposed cavity shell (2a-1) in at least one window (1b-1), the light emitted by LED light source one (3-1) matches with the light guide structure and the exposed cavity shell (2a-1) to form an optical emission structure, such as Figure 16 , 17 As shown;

[0198] This allows the light emitted by the LED light source (3-1) to be emitted outward through the transparent exposed shell of the exposed cavity shell (2a-1), forming a high-brightness light-emitting structure.

[0199] The exposed cavity shell (2a-1) of the LED light source (3-1) may have a protruding strip (the position, shape, structure, and size of which can be designed as needed) serving as an optical structure (2a-8), such as... Figure 18 , 20As shown (the vertical strip in the center of the transparent exposed shell of the exposed cavity shell (2a-1), the light emitted by the LED light source (3-1) is refracted and reflected through this optical structure, which can further optimize the light field distribution and play a role in structural reinforcement.

[0200] The elastic column (1) can be a hollow PU elastomer, PE elastomer, or PVC elastomer with inorganic pigments that have high opacity (poor light transmittance but good color durability).

[0201] The elastic column (1) can also be a hollow transparent PU elastomer, PE elastomer or PVC elastomer with added organic pigments such as fluorescent red or fluorescent yellow. In this case, an LED light source two (3-2) can also be provided. The LED light source two (3-2) is a number of straw hat lamp beads with LAMP packaged with focusing heads. They are vertically or at an assembly elevation angle greater than 45° on the circular circuit board where the control and drive circuit (6) is located. The circular circuit board is fixed in the accommodating cavity (2a-2q) below the built-in cavity shell (2a-2) by a slot and adhesive. The second LED light source (3-2) and the transparent top wall of the built-in cavity shell (2a-2) form a light-emitting structure that includes, but is not limited to, matching the light intensity distribution. The light emitted by the second LED light source (3-2) is projected through the air medium in the hollow cavity of the column (1a) onto the inner wall of the cavity wall (1a-3) of the column (1a), and then emitted outward from the outer wall of the cavity wall (1a-3) of the column (1a) to form a relatively high-position, low-brightness column surface light-emitting structure, thereby forming a light-emitting body that combines high and low positions and high and low brightness, and combines point and surface.

The light-emitting embedded base (2) is embedded from below the base portion (1b) of the elastic column (1) from bottom to top and is assembled with the elastic column (1) as a whole by the assembly fixing structure (8).

[0210] The bottom of the transparent lamp housing (2a) and the bottom of the chassis (1b) combine to form an integral support structure for the bottom of the solar-powered brightening and reflective elastic column. The internal cavity shell (2a-2) in the center of the transparent lamp housing (2a) is embedded in the root of the column (1a) of the elastic column (1). The bottom part of the elastic column (1) is pressed onto the bottom plate (2a-4) and the connecting part (2a-3) of the transparent lamp housing (2a). The exposed cavity shell (2a-1) is embedded in the window (1b-1) of the chassis (1b) and exposed. The light emitted by LED light source 1 (3-1) is matched with the exposed cavity shell (2a-1) to form an optical emission structure. The light emitted by LED light source 1 (3-1) is emitted outward through the transparent exposed shell of the exposed cavity shell (2a-1) to form a high-brightness dot matrix light source emission structure. The elevation angle γ of the main light intensity direction emitted by LED light source 1 (3-1) through the transparent exposed shell of the exposed cavity shell (2a-1) is controlled at: 10°≤γ≤60°, and the vertical emission range angle is controlled at: 45°≤β≤120°, which can be set as needed.

[0211] After the LED light source one (3-1) emits light, it ultimately emits high-brightness light outward from the transparent exposed shells (four sides) of the four exposed cavity shells (2a-1), forming a high-brightness four-sided light-emitting structure. Furthermore, the horizontal light emission angle α of the LED light source one (3-1) emitted from the transparent exposed shell of a single exposed cavity shell (2a-1) is controlled within the range of 45°≤α≤75°, or the horizontal light emission angle α of the LED light source one (3-1) emitted from the transparent exposed shell of a single exposed cavity shell (2a-1) is controlled within the range of 90°≤α≤120°, forming an overall 360° horizontal light-emitting structure with no dead angles.

[0212] Alternatively, after the LED light source one (3-1) emits light, it emits high-brightness light from the transparent exposed shell (single-sided) of one of the exposed cavity shells (2a-1) and low-brightness light from the transparent exposed shells (three-sided) of the other three exposed cavity shells (2a-1), forming a four-sided light-emitting structure with one side having higher brightness and the other three sides having lower brightness. The horizontal range angle α of the light emitted by the LED light source one (3-1) from the transparent exposed shell of a single exposed cavity shell (2a-1) is controlled at: 45°≤α≤75°, or the horizontal range angle α of the light emitted by the LED light source one (3-1) from the transparent exposed shell of a single exposed cavity shell (2a-1) is controlled at: 90°≤α≤120°, forming an overall horizontal 360° light-emitting structure with no dead angles, emphasizing single-sided light emission (one (θ=0°) or two (θ>0°) light emission directions).

[0213] LED light source 1 (3-1) can also be soldered to the left and right sides of the solar photovoltaic panel of the photovoltaic device (4), which makes the light output path in the left and right directions more direct. Combined with the transparent exposed shell of the exposed cavity shell (2a-1), the effective observation range in the horizontal direction is further widened. Especially from the side view, the light of LED light source 1 (3-1) can be captured more clearly, complementing the light emission from other directions, improving the visibility of the overall structure at different angles, and ensuring that even if it is blocked by the elastic column in front, sufficient brightness can be perceived, thereby enhancing the solar brightening, luminous, reflective elasticity. The column serves as a warning or labeling element in practical applications. A composite bottom shell (2b-9a) with a potting hole and perforations aligned with the mounting hole (1b-4) and / or assembly hole one (1b-6) can be provided at the bottom of the lamp housing (2b). This composite bottom shell, combined with the transparent lamp housing (2a), forms a composite shell structure. The composite bottom shell (2b-9a) can have perforations aligned with the mounting hole (1b-4) and / or assembly hole one (1b-6) and is fixed using screws as an assembly fixing structure (8), further enhancing the overall structural strength and waterproof performance of the light-emitting embedded base (2). Figure 27 , 28 As shown,

[0214] LED light source one (3-1) can also be multiple SMD packaged surface mount LEDs, soldered onto the circuit board at an assembly angle between 0° and 45° (inclusive), and fixed in the wire guide groove (2a-3c) of the connecting part (2a-3) by a slot and adhesive. Its light emission direction faces the transparent exposed shell of the exposed cavity shell (2a-1). The light emitted by LED light source one (3-1) matches the exposed cavity shell (2a-1) to form an optical emission structure, such as... Figure 30 , 31 As shown; thus, the light emitted by the LED light source (3-1) is emitted outward through the transparent exposed shell of the exposed cavity shell (2a-1) to form a high-brightness LED light-emitting structure.

[0215] The exposed cavity shell (2a-1) of the LED light source (3-1) may have a protruding strip (the position, shape, structure, and size of which can be designed as needed) serving as an optical structure (2a-8), such as... Figure 21 , 25 As shown in Figure 26 (the transparent exposed shell of the exposed cavity shell (2a-1) has a horizontal strip along the upper edge), the light emitted by the LED light source (3-1) is refracted and reflected through this optical structure, which can further optimize the light field distribution and play a role in structural reinforcement.

[0216] The elastic column (1) can be a hollow PU elastomer, PE elastomer, or PVC elastomer with inorganic pigments that have high opacity (poor light transmittance but good color durability).

[0217] The elastic column (1) can also be a hollow transparent PU elastomer, PE elastomer or PVC elastomer with added organic pigments such as fluorescent red or fluorescent yellow. In this case, an LED light source two (3-2) can also be provided. The LED light source two (3-2) is a number of straw hat lamp beads with LAMP packaged with focusing heads. They are vertically or at an assembly elevation angle greater than 45° on the circular circuit board where the control and drive circuit (6) is located. The circular circuit board is fixed in the accommodating cavity (2a-2q) below the built-in cavity shell (2a-2) by a slot and adhesive. The second LED light source (3-2) and the transparent top wall of the built-in cavity shell (2a-2) form a light-emitting structure that includes, but is not limited to, matching the light intensity distribution. The light emitted by the second LED light source (3-2) is projected through the air medium in the hollow cavity of the column (1a) onto the inner wall of the cavity wall (1a-3) of the column (1a), and then emitted outward from the outer wall of the cavity wall (1a-3) of the column (1a) to form a relatively high-position, low-brightness column surface light-emitting structure, thereby forming a light-emitting body that combines high and low positions and high and low brightness, and combines point and surface.

[0218] This invention relates to a solar-powered reflective elastic column that can be installed on the ground in locations requiring warning or guidance, such as roads, parking lots, construction areas, and community entrances, by screws passing through mounting holes in its base. Compared to existing products, its active light emission brightness is significantly improved. Through optical structure matching, it avoids light energy attenuation caused by light transmission through the column wall, resulting in a light emission brightness several times, even tens of times, higher than traditional designs. It remains clearly visible even in high-illuminance environments such as under streetlights and during the day. It achieves multi-color dynamic warning functionality, displaying synchronous or alternating flashing effects of multiple colors such as red and blue, and red and green, conveying richer traffic safety information and meeting the differentiated visual prompting needs of different scenarios such as road construction, traffic diversion, and emergencies. It exhibits strong luminous stability, with the light emission path of the LED light source unaffected by the yellowing of the column due to aging, ensuring stable and reliable luminous brightness throughout its entire lifespan. Furthermore, it boasts excellent structural durability. By employing pressure-resistant transparent rigid materials and a waterproof encapsulated light-emitting embedded base, it possesses excellent waterproof, dustproof, and pressure and impact resistance properties, adapting to complex and harsh outdoor environments and extending the product's lifespan.
