Description

Technical Field

[0001] The invention relates to the technical field of lane guiding lighting devices, and in particular to a lane guiding solar lighting device for a highway toll station. Background Art

[0002] With the development of society, traffic is becoming more and more complex, bringing new challenges to driving safety and traffic systems. Intelligent transportation systems are an important solution to adapt to these challenges and have become an important part of modern traffic management. The toll gate of the highway is where vehicles gather. Vehicles need to enter the corresponding lanes according to the guidance to ensure long-term and safe traffic. However, due to poor lighting conditions at night and in rain, snow, fog and other weather conditions, safety accidents are easily caused. Therefore, it is very important to set up lane guidance devices at the toll gate, which helps to guide vehicles to drive in the right direction and ensure traffic safety. At present, by installing road stud lights and other devices on the road markings on both sides of the lane, it can play a good guiding and warning role for vehicle drivers. This type of device can reflect the light emitted by the vehicle to play a passive luminous role. After continuous improvement, this type of device can also use the photovoltaic panels set therein to generate solar energy, and then store the electricity in the battery, which can be used for LED lamp beads to actively illuminate at night to strengthen the guiding and warning role. This device also has the advantages of energy saving and environmental protection, convenient installation, low maintenance cost and strong adaptability to various types of roads. However, since this type of device is directly installed and fixed on the road surface, it is inevitable to be crushed by vehicle wheels during use. At the same time, in order to facilitate the reception of sunlight, since the photovoltaic panels are set on the top of the device, they are easily damaged by being crushed or hit by wheels. Summary of the invention

[0003] In view of the above problems, the present invention provides a solar lighting device for lane guidance at a highway toll station, which can not only prevent damage to the photovoltaic panels caused by the wheels of the installed vehicles and increase the service life, but also recycle the emitted light energy. Specifically, the technical solution of the present invention is as follows.

[0004] A solar lighting device for guiding lanes at a highway toll station, comprising: a lamp holder, a battery, a photovoltaic panel, a first collimating lens, a lamp housing, a glass fiber reinforced plastic transparent cover, a reflector and LED lamp beads. The lamp holder is a cylindrical structure with an upper port opening, and the battery, the photovoltaic panel and the first collimating lens are arranged in the inner cavity of the lamp holder from bottom to top in sequence, and the battery is connected to the photovoltaic panel, and the first collimating lens is used to convert the incident light into parallel collimated light to illuminate the photovoltaic panel. The lamp housing is horizontally fixed on the upper port of the lamp holder, and the glass fiber reinforced plastic transparent cover is sealed in the top opening of the lamp housing and aligned with the first collimating lens. The reflector is tilted in the inner cavity of the side wall of the lamp housing, and the LED lamp beads connected to the battery are fixed on the front of the reflector, and a circle of light-transmitting through holes is arranged around each of the LED lamp beads.

[0005] Furthermore, the inner cavity side wall of the lamp holder is provided with a first support plate and a second support plate. The photovoltaic panel is supported and fixed on the first support plate, and the first collimating lens is supported and fixed on the second support plate. Preferably, the second support plate is an arc-shaped plate adapted to the first collimating lens.

[0006] Furthermore, the top of the lamp holder housing is provided with an inwardly extending mounting opening, the glass fiber reinforced plastic transparent cover plate is located in the mounting opening and the two are sealed and connected.

[0007] Furthermore, a third support plate is provided on the inner side wall of the lower end of the installation opening, and the fiberglass transparent cover plate is supported on the support plate.

[0008] Furthermore, a buffer layer is provided between the fiberglass transparent cover plate and the third support plate.

[0009] Furthermore, a horizontal fixing plate is provided on the bottom surface of the lamp holder housing, and the fixing plate has positioning holes so as to fix the lighting device on the road surface.

[0010] Furthermore, the back side of the reflective plate also has a reflective layer, which helps to increase the collection of light.

[0011] Furthermore, a reflective film is provided on the bottom surface of the lamp holder housing below the back surface of the reflective plate, and a second collimating lens is provided above the reflective film.

[0012] Furthermore, the side wall of the lamp holder housing is an inclined rigid light-transmitting plate sealed and fixed on the lamp holder housing so as to protect the reflector and the LED lamp beads.

[0013] Compared with the prior art, the present invention has at least the following beneficial technical effects: (1) The solar lighting device of the present invention sets the photovoltaic panel in the lamp holder below the lamp holder shell. Since the lamp holder is located in the road opening during installation, it helps to prevent the photovoltaic panel from being damaged when the lamp holder shell located on the road is damaged by wheel rolling or collision. At the same time, the above-mentioned setting method increases the distance between the photovoltaic panel and the top opening of the lamp holder shell, resulting in a decrease in the light received by the photovoltaic panel, which in turn reduces the power generation of the photovoltaic panel and reduces the battery life. The first collimating lens above the photovoltaic panel can correct the light path that enters the upper port of the lamp holder through the glass fiber reinforced plastic transparent cover plate, so that part of the light originally incident on the side wall of the lamp holder is diverted and irradiated vertically onto the photovoltaic panel, thereby increasing the light received by the photovoltaic panel and improving the power generation.

[0014] (2) The solar lighting device of the present invention is also provided with a circle of light-transmitting holes around the LED lamp beads. When the LED lamp beads emit light, part of the light can return to the upper port of the lamp holder through the light-transmitting holes. After being corrected by the first collimating lens, the light is irradiated onto the photovoltaic panel again and can be used for light energy generation. On the one hand, the recycling of part of the light energy is achieved, and because the LED lamp beads work under insufficient light conditions such as at night, the recycling of the light energy helps to improve the battery life. On the other hand, it helps to appropriately reduce the light reflected outward by the reflector, alleviate the glare effect of the device, and prevent the driver from getting dizzy and affecting safe driving.

Now further explanation is given in conjunction with the drawings and specific embodiments of the specification.

[0019] refer to Figure 1 , Figure 2 and Figure 3 , an example of a solar lighting device for guiding lanes at a toll station on a highway is provided, comprising: a lamp holder 1, a battery 2, a photovoltaic panel 3, a first collimating lens 4, a lamp housing 5, a glass fiber reinforced plastic transparent cover plate 6, a reflector 7 and an LED lamp bead 8. Specifically: the lamp holder 1 is arranged vertically, and is a cylindrical structure with an upper port opening and a closed bottom surface, including a round cylinder, a square cylinder, etc. Taking the square cylinder adopted in this embodiment as an example, the corresponding photovoltaic panel 3 is a square plate. The battery 2 is fixed on the bottom surface of the lamp holder 1, and the photovoltaic panel 3 is arranged horizontally above the battery 2 and the two are connected by a wire, so that the photovoltaic panel 3 uses the electric energy converted from light energy to store in the battery 2, and is used for the LED lamp bead 8 to actively emit light when the light conditions are insufficient at night, etc., which helps to improve the guiding and warning functions of the device. The first collimating lens 4 is arranged horizontally at the upper port of the lamp holder 1 above the photovoltaic panel 3, and is used to convert the incident light into parallel collimated light to irradiate the photovoltaic panel 3, thereby increasing the amount of light on the photovoltaic panel 3. The first collimating lens 4 can be made of glass or plastic. In addition, a cover body with a detachable connection (such as a threaded connection, etc.) can also be used as the bottom surface of the lamp holder 1.

[0020] The lamp housing 5 is horizontally fixed on the upper port of the lamp holder 1, and the inner cavity of the lamp holder 1 is connected to the inner cavity of the lamp housing 5. The lamp housing 5 is a square structure, and its side wall is an inclined rigid light-transmitting plate sealed and fixed in the lamp housing 5. The rigid light-transmitting plate can be made of glass fiber reinforced plastic, so that it can protect the reflector 7 and the LED lamp beads 8, and facilitate the light of the LED lamp beads 8 to pass through. The reflector 7 is tilted in the inner cavity of the side wall of the lamp housing 5, and its tilt angle can be 30°, 40°, 45°, 50°, etc., and a suitable tilt angle can be selected according to actual needs. The front of the reflector 7 has a reflective layer, and the LED lamp beads 8 are distributed and fixed on the front of the reflector 7 in an array, and the LED lamp beads 8 are connected to the battery 2, so that the LED lamp beads 8 actively emit light under the electric energy provided by the battery 2, and the light is reflected by the reflector 7 and then diverges outward, thereby improving the brightness of the solar lighting device, which helps to guide and warn the vehicle driver. The reflector 7 also has the function of reflecting passive light after receiving the light of the vehicle.

[0021] Each of the LED lamp beads 8 is surrounded by a circle of light-transmitting holes 9, and the diameter of the light-transmitting holes 9 can be 2mm, 3mm, 4mm, etc., which can be selected according to the size of the LED lamp beads 8, the area of ​​the reflector 7 or other factors. The top of the lamp holder housing 5 has an inwardly extending square installation opening 501, and the glass fiber reinforced plastic transparent cover plate 6 is located in the installation opening 501 and the two are sealed and connected, and the glass fiber reinforced plastic transparent cover plate 6 is aligned with the first collimating lens 4. When in use, the lamp holder 1 is installed and fixed in the opening of the road surface, and the lower surface of the lamp holder housing 5 is attached to the road surface. In the embodiment of the present invention, the photovoltaic panel 3 is arranged in the lamp holder 1 below the lamp holder housing 5, so that when the lamp holder housing 5 located on the road surface is damaged by wheel rolling or collision, the photovoltaic panel 3 located below the road surface can be well prevented from being damaged due to pressure, thereby improving the service life of the photovoltaic panel 3. However, due to the above structure, the distance between the photovoltaic panel 3 and the top opening of the lamp housing 5 increases, resulting in a decrease in the light received by the photovoltaic panel 3, which in turn leads to a decrease in the power generation of the photovoltaic panel 3 and a decrease in the endurance of the battery 2. The first collimating lens 4 above the photovoltaic panel 3 can correct the path of the light entering the upper port of the lamp holder 1 through the glass fiber reinforced plastic transparent cover plate 6, so that part of the light originally incident on the side wall of the lamp holder 1 is intercepted by the first collimating lens 4 and then redirected and vertically irradiated onto the photovoltaic panel 3, thereby increasing the light received by the photovoltaic panel 3 and improving the power generation.

[0022] In addition, the light-transmitting through hole 9 around the LED lamp bead 8 of this embodiment allows part of the light from the LED lamp bead 8 to return to the upper port of the lamp holder 1 through the light-transmitting through hole 9, and then irradiate the photovoltaic panel 3 again after correction by the first collimating lens 4, and store the electricity in the storage battery 2 after power generation. On the one hand, the recycling of part of the light energy is realized (such as Figure 2 In addition, since the LED lamp beads 8 work at night and other conditions with insufficient light, the electric energy in the battery 2 is continuously consumed and cannot be replenished. The cooperation between the LED lamp beads 8 and the light-transmitting through holes 9 can realize the recycling of part of the light energy, thereby helping to improve the endurance of the battery 2. On the other hand, it helps to appropriately reduce the light reflected by the reflector 7, preventing the driver from being dizzy and affecting safe driving.

[0023] refer to Figure 1 In another embodiment, the bottom surface of the lamp holder shell 5 of the highway toll station lane guiding solar lighting device in the above embodiment has a horizontal outwardly extending fixing plate 504, and the fixing plate 504 has a positioning hole 505, so that fasteners such as bolts can be passed through the positioning hole and fastened to the ground, thereby fixing the lighting device as a whole on the road surface.

[0024] refer to Figure 2 In another embodiment, the inner cavity side wall of the lamp holder 1 of the lane guiding solar lighting device for the highway toll station in the above embodiment is provided with a first support plate 101 and a second support plate 102. The support plate is composed of four plate bodies evenly distributed on the inner cavity side wall of the lamp holder 1. Among them: the photovoltaic panel 3 is supported and fixed on the first support plate 101, and the first collimating lens 4 is supported and fixed on the second support plate 102. In a more preferred embodiment, the second support plate 102 is an arc-shaped plate adapted to the first collimating lens 4, so as to form a better supporting effect on the first collimating lens 4.

[0025] refer to Figure 2 In another embodiment, the lower inner side wall of the installation opening 501 of the lane guide solar lighting device for the highway toll station in the above embodiment is provided with a third support plate 502, and the third support plate is composed of four plates evenly distributed on the inner side wall of the lamp holder 1. The FRP transparent cover plate 6 is supported on the support plate 502, and the two are sealed and connected by a waterproof sealant. In a more preferred embodiment, a buffer layer 503 is provided between the FRP transparent cover plate 6 and the support plate 502. The buffer layer 503 can be made of rubber, flexible plastic and other materials to provide buffering when the FRP transparent cover plate 6 is under pressure to prevent damage.

[0026] In another embodiment, the back side of the reflective plate 7 of the lane guide solar lighting device for the highway toll station in the above embodiment also has a reflective layer. The reflective layer helps to reflect the light that enters the inner cavity of the lamp holder housing 5 through the light-transmitting through hole 9, and then incident on the first collimating lens 4 and corrected before incident on the photovoltaic panel 3, thereby improving the light collection capacity and utilization rate. Further, In a more preferred embodiment, reference Figure 2 and Figure 4 In the previous embodiment, a reflective film is provided on the bottom surface of the lamp housing 5 below the back surface of the reflective plate 7, and a second collimating lens 10 is provided above the reflective film. A second long-strip collimating lens 10 is provided along each of the four bottom edges of the lamp housing 5. Similarly, the second collimating lens 10 can be made of glass or plastic. The second collimating lens 10 can align the light (including from the light-transmitting through hole 9 and the glass fiber reinforced plastic transparent cover plate 6) incident on the bottom surface of the lamp housing 5 so that it is vertically incident on the reflective film on the bottom surface of the lamp housing 5, and then is vertically reflected by it to the reflective layer on the back surface of the reflective plate 7 and then re-reflected back to the first collimating lens 4, and finally irradiated to the photovoltaic panel 3 for power generation, thereby further improving the collection and utilization rate of light.
