Description

Technical Field

[0001] This utility model relates to the field of road traffic signs, specifically an embedded road surface indicator light. Background Technology

[0002] Currently, directional signs or painted arrows are commonly used in parks, streets, communities, and underpasses to guide people unfamiliar with the area. While these signs are usually non-illuminated and visible in bright light, their visibility is significantly reduced in low-light conditions, such as in underpasses, subway station platforms, large stadium passageways, and shopping mall passageways—areas with high pedestrian traffic. This can cause pedestrians to lose their way and become stuck, leading to congestion. Some systems use fluorescent paint to draw arrows on the ground, but the paint wears off as pedestrians walk on it, causing the signs to disappear. Another approach is to use lightboxes, where incandescent or fluorescent lights are installed inside transparent boxes that indicate road directions, allowing pedestrians to see the lightboxes even in dimly lit environments. These lightboxes are generally only able to be installed at high places and cannot be placed on the ground. Due to wind and rain, the boxes are prone to water ingress, causing circuit damage, short lifespan, high operating costs, and difficult maintenance. As a result, the lightbox signs become mere decorations, unable to fulfill their guiding function, and their application scenarios are limited. Utility Model Content

[0003] To address the aforementioned shortcomings of existing technologies, this invention provides an embedded road indicator light. By placing the illuminated indicator light on the ground, it can provide clear guidance for pedestrians.

[0023] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.

[0024] In the description of this utility model, it should be understood that the orientation or positional relationship indicated by directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" is usually based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing this utility model and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this utility model. The directional terms "inner" and "outer" refer to the inner and outer contours relative to the outline of each component itself.

[0025] The present invention will now be described in detail with reference to the accompanying drawings and embodiments, as shown in the attached drawings. Figure 1-3 As shown, an embedded road indicator light is provided. The road indicator light also includes a housing 1. The housing 1 is made of stainless steel sheet metal welding, which can withstand corrosion and is not easy to rust. It can provide stable support and protection for internal components. The bottom perimeter and four corners of the housing 1 are provided with reinforcing ribs to improve structural strength and prevent deformation. The four corners of the housing 1 are provided with fixing holes.

[0026] The housing 1 houses a controller 3, mounted on an internal bracket, used to control the brightness and color change of the lights. A battery 2 is housed inside the housing 1, providing backup power during power outages. A square ring boss is located at the upper part of the housing 1, with an aluminum silicate board heat insulation plate 4 connected to its upper end. This reduces the aging of the battery and controller caused by light and high temperatures. The upper end of the heat insulation plate 4 is connected to a fixing frame 5, which has a groove that matches the contour of the light-emitting element 8. The light-emitting element 8 is embedded in the groove within the fixing frame 5. The light-emitting element 8 is made of highly transparent acrylic sheet with a sandblasted surface, effectively transmitting light. A lamp bead slot is located on the lower surface of the light-emitting element 8 for emitting light. A light strip 7 is attached to the LED bead slot on the lower end face of body 8. The light strip 7 is a programmable LED light strip, which can be controlled by controller 3 to adjust the brightness and color of the light to suit different scenarios. LED beads are evenly distributed on the light strip 7 and embedded in the LED bead slot of the corresponding light-emitting body 8. Light-shielding and reflective stickers are attached around the acrylic sheet and at the bottom to reduce scattering and reflection of light when it enters and leaves the sheet, thereby improving the utilization rate and brightness of the light. The sheet absorbs the light. The sandblasted acrylic sheet has light guide points on its surface. When the light hits each light guide point, the reflected light will diffuse in all directions and then break the reflection conditions and be emitted from the front of the acrylic light guide plate, ultimately forming a uniform light emission effect.

[0027] The upper side of the fixed frame 5 is provided with a fixing hole for fixing the photoresistor 6. The photoresistor 6 is electrically connected to the controller 3 and can detect the ambient light intensity. When the ambient light is weak, it transmits the signal to the controller 3, and the controller 3 then transmits the signal to the light strip 7 to light up the light source 8.

[0028] It should be noted that the light-emitting body 8 can be an arrow indicating the direction, or it can be used for warning purposes, reminding people of safety, or it can be used to delineate areas. Therefore, the shape of the light-emitting body 8 varies depending on its purpose and is not limited to indicating direction.

[0029] A first sealing gasket 9 made of silicone rubber is fixedly connected to the inner edge of the upper end of the housing 1. A tempered glass 10 is connected to the upper end of the fixed frame 5, which can clearly transmit the light of the light source 8, effectively resist pressure, prevent the surface from being scratched and worn, and has an anti-slip layer on the surface, which has good friction and prevents slipping. The four sides of the tempered glass 10 are tightly connected to the inner side of the first sealing gasket 9, which can effectively prevent water from entering the housing for a long time and improve the service life. A square frame 12 is connected to the upper end of the first sealing gasket 9. A second sealing gasket 11 is pasted and connected to the inner side of the lower edge of the center of the square frame 12. The lower end of the second sealing gasket 11 is tightly connected to the tempered glass 10. The square frame 12 is fixedly connected to the housing 1 by bolts. The first sealing gasket 9 and the second sealing gasket 11 are pressed into the square frame by bolts to seal the water around and on the top, preventing corrosion of internal components.

[0030] In the installation area, determine a suitable distance and location, and excavate a pit that is suitable for the volume of the box 1. Construct a base with concrete at the bottom of the pit, with fixing bolts at the four corners. After the base solidifies, place the road indicator light on the base and fix it to the base by passing the bolts through the fixing holes of the box 1. One end of the wire is electrically connected to the storage battery 2, and the other end of the wire is led out from the device and connected to the street light through a PVC pipe to provide power to the device. The storage battery 2 can continue to light up the indicator light when the power is off, providing guidance for pedestrians.

[0031] After the road indicator light in box 1 is installed, the surrounding area is backfilled and compacted with concrete. The square frame 12 of the road indicator light is flush with the ground to prevent obstruction to pedestrians.

[0032] For the controller, any commercially available product will suffice, such as Omron CP1E / CP1L series PLC or Siemens S7-1200 PLC.

[0033] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. The scope of this invention is defined by the appended claims rather than the foregoing description; therefore, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this invention, and no reference numerals in the claims should be construed as limiting the scope of the claims.
