Description

Technical Field

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

[0002] With the development of society, traffic has become increasingly complex, bringing new challenges to driving safety and the traffic system. Intelligent transportation systems are important solutions to adapt to these challenges and have become an important part of modern traffic management. The toll station of a highway is a place where vehicles gather. Vehicles need to enter the corresponding lanes according to the guidance to ensure traffic smoothness and safety. However, at night and in weather such as rain, snow, and fog, due to poor lighting conditions, safety accidents are likely to occur. Therefore, it is very important to set up lane guiding devices at toll stations, which helps to guide vehicles to drive in the correct direction and ensure traffic safety. Currently, by installing devices such as spike lights at the road markings on both sides of the lane, it can play a good guiding and warning role for vehicle drivers. Such devices can reflect the light emitted by vehicles to play a passive lighting role. After continuous improvement, such devices can also use the photovoltaic panels installed in them for solar power generation, and then store the electric energy in the storage battery for the LED lamp beads to emit light actively at night, strengthening the guiding and warning effects. This kind of device also has the advantages of energy conservation and environmental protection, convenient installation, low maintenance cost, and strong adaptability to various roads. However, since such devices are directly installed and fixed on the road surface, they are inevitably crushed by vehicle wheels during use. At the same time, in order to facilitate receiving sunlight, since the photovoltaic panels are set on the top of the device, they are easily damaged under the rolling and impact of vehicle wheels. Summary of the Invention

[0003] Aiming at the above problems, the present invention provides a solar lighting device for lane guiding at highway toll stations, which can not only prevent the damage of the photovoltaic panel caused by vehicle wheels, improve the service life, but also recycle and utilize the emitted light energy. Specifically, the technical solution of the present invention is as follows.

[0004] A solar lighting device for lane guidance at highway toll stations, comprising: a lamp base, a storage battery, a photovoltaic panel, a first collimating lens, a lamp head housing, a fiberglass transparent cover plate, a reflector and LED lamp beads. Among them: the lamp base is a cylindrical structure with an open upper port, the storage battery, the photovoltaic panel and the first collimating lens are sequentially arranged in the inner cavity of the lamp base from bottom to top, and the storage battery is connected to the photovoltaic panel. The first collimating lens is used to convert incident light into parallel collimated light and irradiate it on the photovoltaic panel. The lamp head housing is horizontally fixed on the upper port of the lamp base, and the fiberglass transparent cover plate is hermetically covered in the top opening of the lamp head housing and aligned with the first collimating lens. The reflector is inclined and arranged in the inner cavity of the side wall of the lamp head housing, and the LED lamp beads connected to the storage battery are fixed on the front surface of the reflector, and a circle of light-transmitting through holes are arranged around each LED lamp bead.

[0005] Further, the inner cavity side wall of the lamp base has 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] Further, the top of the lamp head housing has an inward-extending mounting opening, and the fiberglass transparent cover plate is located in the mounting opening and the two are hermetically connected.

[0007] Further, the inner side wall at the lower end of the mounting opening has a third support plate, and the fiberglass transparent cover plate is supported on this support plate.

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

[0009] Further, the bottom surface of the lamp head housing has a horizontal fixing plate, and the fixing plate has positioning holes for fixing the lighting device on the road surface.

[0010] Further, the back surface of the reflector also has a reflective layer, which helps to increase the collection of light.

[0011] Further, there is a reflective film on the bottom surface of the lamp head housing below the back surface of the reflector, and a second collimating lens is above the reflective film.

[0012] Further, the side wall of the lamp head housing is an inclined rigid light-transmitting plate hermetically fixed on the lamp head housing 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:

[0014] (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.

[0015] (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.

They are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the devices or elements referred to need to have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be construed as a limitation of the present invention. Now, it will be further described in conjunction with the accompanying drawings of the specification and specific embodiments.

[0024] Reference Figure 1 、 Figure 2 and Figure 3 , an example of a lane guiding solar lighting device for highway toll stations is provided, including: lamp holder 1, storage battery 2, photovoltaic panel 3, first collimating lens 4, lamp head housing 5, fiberglass transparent cover plate 6, reflector 7 and LED lamp beads 8. Specifically: The lamp holder 1 is vertically arranged and is a cylindrical structure with an open upper port and a closed bottom surface, including a cylindrical tube, a square tube, etc. Taking the square tube adopted in this embodiment as an example, the corresponding photovoltaic panel 3 is a square plate. The storage battery 2 is fixed on the bottom surface of the lamp holder 1, and the photovoltaic panel 3 is horizontally arranged above the storage battery 2 and the two are connected by wires, so as to store the electric energy converted by the photovoltaic panel 3 using light energy in the storage battery 2 for the LED lamp beads 8 to emit light actively under insufficient lighting conditions such as at night, which helps to improve the guiding and warning functions of the device. The first collimating lens 4 is horizontally arranged 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 and irradiate it on the photovoltaic panel 3 to increase the light amount received by 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.

[0025] The lamp head housing 5 is horizontally fixed on the upper port of the lamp base 1, and the inner cavities of the lamp base 1 and the lamp head housing 5 are in communication with each other. The lamp head housing 5 has a square structure, and its side walls are inclined rigid light-transmitting plates hermetically fixed in the lamp head housing 5. The rigid light-transmitting plates can be made of fiberglass reinforced plastic, so that they can protect the reflector 7 and the LED lamp beads 8, and at the same time facilitate the light of the LED lamp beads 8 to penetrate. The reflector 7 is inclined and arranged in the inner cavity of the side wall of the lamp head housing 5, and its inclination angle can be 30°, 40°, 45°, 50°, etc., or a suitable inclination angle can be selected according to actual needs. The front surface of the reflector 7 has a reflective layer, and the LED lamp beads 8 are fixedly distributed in an array on the front surface of the reflector 7, and the LED lamp beads 8 are connected to the storage battery 2, so that the LED lamp beads 8 can emit light actively under the electric energy provided by the storage battery 2. Some of the light is scattered outward after being reflected by the reflector 7, improving the brightness of the solar lighting device and helping to guide and warn vehicle drivers. The reflector 7 also has the function of reflecting and emitting light passively after receiving the light of the vehicle.

[0026] A circle of light-transmitting through holes 9 are arranged around each of the LED lamp beads 8. The diameter of the light-transmitting through holes 9 can be 2 mm, 3 mm, 4 mm, etc., and can be specifically 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 head housing 5 has an inward-extending square mounting opening 501. The fiberglass transparent cover plate 6 is located in the mounting opening 501 and is hermetically connected to it, and the fiberglass transparent cover plate 6 is aligned with the first collimating lens 4. When in use, the lamp base 1 is installed and fixed in the road surface opening, and the lower surface of the lamp head housing 5 is attached to the road surface. In the embodiment of the present invention, the photovoltaic panel 3 is arranged in the lamp base 1 below the lamp head housing 5, so that when the lamp head housing 5 located on the road surface is damaged by being run over or impacted by a wheel, it can well prevent the photovoltaic panel 3 located below the road surface from being damaged due to pressure, and improve 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 head housing 5 increases, resulting in a reduction in the light received by the photovoltaic panel 3, and further leading to a reduction in the power generation of the photovoltaic panel 3 and a decrease in the battery life of the storage battery 2. The first collimating lens 4 above the photovoltaic panel 3 can correct the light path of the light entering the upper port of the lamp base 1 through the fiberglass transparent cover plate 6, so that some of the light that was originally incident on the side wall of the lamp base 1 is intercepted by the first collimating lens 4 and then redirected and vertically irradiated onto the photovoltaic panel 3, increasing the light received by the photovoltaic panel 3 and improving the power generation.

[0027] In addition, some of the light emitted by the LED lamp beads 8 around the light-transmitting through holes 9 in this embodiment can pass through the light-transmitting through holes 9 and return to the upper port of the lamp base 1, and after being corrected by the first collimating lens 4, it irradiates the photovoltaic panel 3 again and is stored in the storage battery 2 after power generation. On the one hand, the recycling of some light energy is realized (as shown by the arrow line in Figure 2 ), and since the LED lamp beads 8 work under conditions of insufficient light such as at night, the electric energy in the storage battery 2 is continuously consumed and cannot be replenished at the same time. The cooperation of the LED lamp beads 8 and the light-transmitting through holes 9 can realize the recycling of some light energy, which helps to improve the endurance of the storage battery 2. On the other hand, it helps to appropriately reduce the light reflected by the reflector 7 in the opposite direction, preventing the vehicle driver from being dazzled and affecting safe driving.

[0028] Refer to Figure 1 , in another embodiment, the bottom surface of the lamp head housing 5 of the highway toll station lane guiding solar lighting device in the above embodiment has a horizontally extending fixing plate 504, and the fixing plate 504 has positioning holes 505, so that fasteners such as bolts can be passed through the positioning holes and fastened in the ground to fix the whole lighting device on the road surface.

[0029] Refer to Figure 2 , in another embodiment, the inner cavity side wall of the lamp base 1 of the highway toll station lane guiding solar lighting device in the above embodiment has a first support plate 101 and a second support plate 102. The support plates are composed of four plate bodies evenly distributed on the inner cavity side wall of the lamp base 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 better embodiment, the second support plate 102 is an arc-shaped plate adapted to the first collimating lens 4 to form a better supporting effect on the first collimating lens 4.

[0030] Refer to Figure 2 , in another embodiment, the lower inner side wall of the installation opening 501 of the highway toll station lane guiding solar lighting device in the above embodiment has a third support plate 502, and the third support plate is composed of four plate bodies evenly distributed on the inner cavity side wall of the lamp base 1. The fiberglass transparent cover plate 6 is supported on the support plate 502, and the two are sealed and connected by a waterproof sealant. In a better embodiment, there is a buffer layer 503 between the fiberglass transparent cover plate 6 and the support plate 502. The buffer layer 503 can be made of materials such as rubber and flexible plastic to buffer when the fiberglass transparent cover plate 6 is pressed and prevent damage.

[0031] In another embodiment, the back surface of the reflector 7 of the highway toll station lane guiding solar lighting device of the above embodiment also has a reflective layer. The reflective layer helps to reflect the light that enters the inner cavity of the lamp head housing 5 through the light-transmitting through holes 9, and then is incident on the first collimating lens 4 and corrected and then incident on the photovoltaic panel 3, thereby improving the light collection ability and utilization rate. Further,

[0032] In a better embodiment, referring to Figure 2 and Figure 4 , there is a reflective film on the bottom surface of the lamp head housing 5 below the back surface of the reflector 7 of the previous embodiment, and a second collimating lens 10 is provided above the reflective film. A strip-shaped second collimating lens 10 is provided along each of the four bottom edges of the lamp head housing 5. Similarly, the second collimating lens 10 can be made of glass or plastic. The second collimating lens 10 can collimate the light incident on the bottom surface of the lamp head housing 5 (including the light from the light-transmitting through holes 9 and the fiberglass transparent cover plate 6) so that it is vertically incident on the reflective film on the bottom surface of the lamp head housing 5, and then is vertically reflected onto the reflective layer on the back surface of the reflector 7 and then re-reflected back to the first collimating lens 4, and finally irradiated onto the photovoltaic panel 3 for power generation, thereby further improving the light collection and utilization rate.

[0033] Finally, it should be noted that any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention. Although the specific embodiments of the present invention have been described above in conjunction with the drawings, it is not a limitation to the protection scope of the present invention.
