Description

Technical Field

[0001] The utility model relates to a multifunctional low - level traffic light, in particular to a multifunctional low - level traffic light for guardrail, road lighting and warning guidance. Background Art

[0002] Existing road lighting systems usually include various lamps such as low - level lighting lamps, warning guidance lamps and fog lamps. Each lamp only has a single function and is used for different lighting and warning guidance needs respectively.

[0003] Low - level lighting lamps are mainly used to illuminate the lower parts of the road, such as sidewalks, bicycle lanes and some auxiliary roads. These lamps are usually installed at a lower position to avoid disturbing the driver's line of sight. However, while providing lighting, they may not provide sufficient warning functions. Warning guidance lamps are usually used in areas that require special attention from drivers, such as around schools, construction areas or accident - prone sections. These lamps attract the driver's attention by emitting strobe or specific - colored light, but they are usually independent of the main lighting system. In foggy or rainy days with low visibility, fog lamps can provide additional lighting and warning. They usually emit yellow or red light to improve visibility under bad weather conditions.

[0004] However, in the prior art, traffic lights with various different functions are single - functional, and various types of traffic lights are arranged in a decentralized manner. This decentralized lamp arrangement method requires more lamps to be installed, which not only increases the number of lamps and construction costs, increases material and labor costs, but also increases maintenance costs. In addition, different lamps work independently and lack coordination, which may lead to ineffective use of energy. The simultaneous use of multiple lamps may cause visual confusion for drivers and affect driving safety. Moreover, the simultaneous use of multiple lamps may cause visual interference, especially at night or in low - visibility situations. This not only affects the driver's judgment but also may increase the risk of traffic accidents.

[0005] Therefore, there is an urgent need in the market for a traffic light that can be compatible with multiple functions and reduce the number of lamps to reduce construction costs and improve road driving safety. Summary of the Utility Model

[0006] In view of the above - mentioned disadvantages of the prior art, the technical problem to be solved by the utility model is to provide a multifunctional low - level traffic light that combines lighting and warning guidance functions and can reduce the number of road lamps.

[0007] To achieve the above object, the utility model provides a multifunctional low-position traffic light, which includes a top cover and a light-emitting cover. The top of the light-emitting cover is provided with an opening, and the top cover is installed on the top of the light-emitting cover so as to form an installation cavity between the light-emitting cover and the top cover. The light-emitting cover has a front light-emitting surface and a side light-emitting surface. An installation frame is arranged in the installation cavity. The installation frame includes a front mounting plate facing the front light-emitting surface and a side mounting plate facing the side light-emitting surface. A lighting light source is installed on the front mounting plate, and a strobe light source is installed on the side mounting plate.

[0008] Using the multifunctional low-position traffic light of the utility model can provide lighting function and warning and guiding function for the road. Compared with the situation of separately arranging traffic lights dedicated to lighting and traffic lights dedicated to warning and guiding on the road, it can reduce the number of lamps, reduce the construction cost, and achieve cost reduction and efficiency improvement.

[0009] Preferably, a power supply board is further installed on the top cover. The lighting light source and the strobe light source are connected to the power supply board through conductive connection wires. A control circuit is arranged in the power supply board for controlling the working modes of the lighting light source and the strobe light source.

The on-off of the power supply and the flashing frequency of the light source are controlled through the remote control system, and the light source module realizes the rapid switching of the flashing frequency of the light source through electronic control technology.

[0011] Further, the power control wire is connected to the remote control system. The remote control system can coordinately control a large number of traffic lights on the road, so that the traffic lights can work in a unified and coordinated manner.

[0012] Preferably, a breather is further arranged on the light-emitting cover. The breather can make the installation cavity ventilated to remove the entered water vapor, and can adjust the internal air pressure and humidity to protect the internal components.

[0013] Preferably, the installation frame is made of an opaque material. The installation frame made of an opaque material can isolate the lighting light source and the strobe light source, so that each light source emits light independently without mutual influence.

[0014] Preferably, both the lighting light source and the strobe light source adopt LED light sources. The LED light sources have high brightness, low power consumption, less heat generation, and a long service life.

[0015] Preferably, a lens plate is further installed on the lighting light source, and the lens plate is located between the lighting light source and the front light-emitting surface. The lens plate can optimize the light emitted by the lighting light source so that the light will not be dazzling and affect the driver's line of sight.

[0016] Preferably, the top cover is connected to the installation connecting arm through a rotatable disk with an adjustable angle. In this way, the irradiation angle of the traffic light can be adjusted through the rotatable disk to adapt to the undulation of the road surface and the structural changes of the guardrail, so that the light emitted by the illumination light source and the strobe light source of the traffic light can irradiate objects such as the road surface and the guardrail at an appropriate angle.

[0017] Preferably, a side light-emitting surface is provided on each of the left and right sides of the front light-emitting surface, and a side mounting plate is provided on each of the two sides of the front mounting plate of the mounting frame, and a strobe light source is mounted on each of the two side mounting plates.

[0048] Such as Figure 1 And Figure 2As shown in the figure, the utility model provides a multi-functional low-position traffic light, which includes a top cover 1 and a light-emitting cover 10. The top of the light-emitting cover 10 is provided with an opening, and the top cover 1 is installed on the top of the light-emitting cover 10 so as to form an installation cavity between the light-emitting cover 10 and the top cover 1. The light-emitting cover 10 has a front light-emitting surface 19 and a side light-emitting surface 20. An installation frame 4 is arranged in the installation cavity. The installation frame 4 includes a front mounting plate 21 facing the front light-emitting surface 19 and a side mounting plate 22 facing the side light-emitting surface 20. A lighting light source 5 is installed on the front mounting plate 21, and a strobe light source 17 is installed on the side mounting plate 22.

[0049] A lighting light source 5 and a strobe light source 17 are installed in the multi-functional low-position traffic light of the utility model. The light emitted by the lighting light source 5 is emitted from the front light-emitting surface 19 and is used to provide lighting for low-position road buildings such as guardrails and roads. The light emitted by the strobe light source 17 is emitted from the side light-emitting surface 20 and is used to provide a warning and guiding light signal. In this way, the multi-functional low-position traffic light of the utility model can provide a lighting function and a warning and guiding function for the road. Compared with the situation of separately arranging traffic lights dedicated to lighting and traffic lights dedicated to warning and guiding on the road, it can reduce the number of lamps and the construction cost, and achieve cost reduction and efficiency improvement. It can be seen that the structural main body of the multi-functional low-position traffic light of the utility model can be compatible with the functions of conventional low-position lighting, road / tunnel warning and guiding lights, and fog lights in foggy days, realizing one lamp with multiple functions, effectively reducing the number of lamps and the construction cost, and improving the driving safety on the road.

[0050] In order to achieve better lighting effects, long lifespan, energy conservation and environmental protection for traffic lights, both the lighting source and the stroboscopic light source of a multifunctional low-position traffic light of the present utility model adopt LED light sources, which have advantages such as high brightness, low energy consumption and long lifespan. LED light has directivity and a certain divergence angle. LED is a cold light source, and one of its remarkable features is low energy consumption. The apparent power of a single light-emitting unit of the signal lamp with an LED light source is generally between 12 VA and 25 VA, far lower than that of the signal lamp with an incandescent bulb light source (80 W to 100 W) and the signal lamp with a low-voltage halogen tungsten bulb light source (40 VA to 60 VA), having significant energy-saving advantages. The stroboscopic light source in the traffic light needs to have sufficient brightness so as to be clearly visible under various environmental conditions. The stroboscopic light source may produce the visual persistence effect, affecting the driver's judgment of the surrounding environment. When designing, the flashing frequency and brightness of the stroboscopic light source need to be considered to reduce this effect. The stroboscopic light source flashes rapidly, and the flashing speed of the stroboscopic light source needs to meet specific standards to ensure its warning effect. Since the traffic light needs to operate for a long time, the stroboscopic light source needs to adopt durable materials and designs to ensure long-term stable operation. Modern stroboscopic light sources usually adopt LED technology to reduce energy consumption and improve energy efficiency. The working environment of the traffic light is relatively harsh, so the reliability requirements for the lamps are relatively high. The theoretical lifespan of the LED signal lamp can reach 100,000 hours, and the actual service life is greater than 50,000 hours, far higher than that of the incandescent bulb (1,000 hours) and the low-voltage halogen tungsten bulb (2,000 hours). This significantly reduces the maintenance cost.

[0051] As Figure 1 and Figure 2 shown, the space between the top cover 1 and the light-emitting cover 10 forms an installation cavity for accommodating the electronic components of the traffic light and protecting the internal structure. Electrical components such as the light source, power supply board, and conductive connection wires of the traffic light are all accommodated in the installation cavity. The mounting bracket is also arranged in the installation cavity. The front mounting plate is a part of the mounting bracket, facing the front light-emitting surface, and is used for mounting the lighting source; the side mounting plate faces the side light-emitting surface and is used for mounting the stroboscopic light source.

[0052] In order to enable the light source to generate less heat, both the lighting source 5 and the stroboscopic light source 17 adopt high-brightness and low-power-consumption LED light sources. The entire lamp is connected to a remote control system to switch on and off the lamp according to the instructions of the control center; the lamp adopts high-efficiency heat dissipation materials and designs to ensure the stability and long lifespan of the LED light source during long-term operation. At the same time, the light-emitting cover 10 and the top cover 1 are made of waterproof, dustproof, and anti-corrosion materials to improve the durability and safety of the lamp.

[0053] To facilitate power supply to the lighting source 5 and the stroboscopic light source 17, as Figure 2As shown, a power board 2 is also installed on the top cover 1. The power board 2 is installed on the top cover 1 through the first screw 3. The lighting source 5 and the stroboscopic light source 17 are connected to the power board 2 through the conductive connecting wire 23. A control circuit is provided in the power board 2 to control the working modes of the lighting source 5 and the stroboscopic light source 17. A waterproof cable joint 13 is also provided on the light-emitting cover 10. A power control line 15 is passed through the waterproof cable joint 13. The power control line 15 is connected to the power board 2. The power control line 15 is connected to a remote control system to control the on / off of the power supply and the flashing frequency of the light source through the remote control system. The light source module realizes the rapid switching of the light source flashing frequency through electronic control technology.

[0054] In order to ensure the effective realization of the lighting function and warning function of the traffic light, it is necessary to ensure that the lighting source and the stroboscopic light source can work in coordination under different conditions and avoid mutual interference. In order to prevent the light sources in the installation cavity from interfering with each other, the mounting bracket 4 is made of an opaque material. In this way, the light emitted by each light source basically exits from its respective light-emitting surface and will not affect the light of other light sources. In order to adjust the light effect of the lighting source 5, a lens plate 6 is also installed on the lighting source 5. The lens plate 6 is located between the lighting source 5 and the front light-emitting surface 19. The lens plate 6 is installed on the lighting source 5 and the mounting bracket 4 through the second screw 7. The lens plate 6 is provided with an array of small lenses, which can optimize the light so that the light will not be dazzling and affect the driver's line of sight. The array of small lenses can effectively distribute the light emitted by the LED light source to form a uniform light distribution, reduce the dark areas and over-bright areas of the lighting, thereby improving the uniformity of road lighting. Through the refraction and scattering effects of the small lenses, the intensity of the light can be reduced, preventing the light from directly shining into the driver's eyes and reducing the impact of glare on the driver's line of sight. This design helps to improve the safety of road driving. The shape and size of the small lenses will affect the focusing and distribution of the light. The designer needs to determine the optimal shape and size of the lens and the lens arrangement according to the specific application scenario and lighting requirements of the traffic light.

[0055] As Figure 2 shown, the mounting bracket 4 is installed on the top cover 1 through the third screw 8. The light-emitting cover 10 is installed on the top cover 1 through the fourth screw 11. On the left and right sides of the front light-emitting surface 19 of the light-emitting cover 10, there is a side light-emitting surface 20 each ( Figure 2 only the side light-emitting surface 20 on the right side of the front light-emitting surface 19 is marked in Figure 2 ), and on both sides of the front mounting plate 21 of the mounting bracket 4, there is a side mounting plate 22 each ( Figure 2Only the stroboscopic light source 17 on the side mounting plate 22 on the right side of the front mounting plate 21 is identified. The lighting light source 5 and the stroboscopic light source 17 control the on / off of the power supply and the flashing frequency of the light source through a remote control system. The light source module realizes the rapid switching of the light source flashing frequency through electronic control technology. The remote control system can realize the real-time monitoring and automatic adjustment of the lighting system by integrating sensors and communication technologies. Such a system can automatically adjust the lighting intensity and mode according to environmental conditions and traffic flow, improving energy efficiency and safety.

[0056] In the conventional lighting mode, low-level lighting is achieved at night, and the lighting light source 5 emits white light to achieve constant low-level lighting at night; in the warning and guiding mode, the two stroboscopic light sources 17 on the mounting bracket 4 emit stroboscopic lights. One stroboscopic light source 17 emits yellow stroboscopic light, and the other stroboscopic light source 17 emits white stroboscopic light; in the foggy weather mode, the stroboscopic light source 17 emits yellow stroboscopic light. The product usage method is that the lighting light source 5 is constantly on at night, the left stroboscopic light source 17 emits yellow stroboscopic light and the right stroboscopic light source 17 emits white stroboscopic light at night for warning and guiding, and the yellow light flashes in foggy weather, improving road driving safety. The effect of one lamp being compatible with multiple functions is achieved. On sections that require multiple types of lighting, it can reduce the number of lamps for users, reduce construction costs, and achieve the purpose of cost reduction and efficiency increase.

[0057] As Figure 2 shown, the light-emitting cover 10 and the top cover 1 are connected by the fourth screw 11, and the light-emitting cover 10 and the top cover 1 are sealed by the gasket 9 to prevent rainwater from entering. In order to prevent the accumulation of water vapor in the installation cavity of the light-emitting cover 10, a breather 12 is also provided on the light-emitting cover 10. The breather 12 has a waterproof function and can also make the installation cavity ventilated and breathable to remove the entered water vapor. The breather can adjust the internal air pressure and humidity to protect the internal components.

[0058] To facilitate the adjustment of the irradiation angle of the traffic light, as Figure 1 and Figure 2 shown, the top cover 1 is connected to the installation connecting arm 18 through a rotatable disk 14 with an adjustable angle. The fifth screw 16 passes through the connecting arm, the rotatable disk 14 and the connecting ear 24 on the top cover 1 and is tightened. In this way, the irradiation angle of the traffic light can be adjusted through the rotatable disk 14.

[0059] A multi-functional low-position traffic light of the present utility model adopts an integrated structure. The top cover and the light-emitting cover form a closed installation cavity, integrating all electronic components and light sources. The lighting light source and the strobe light source are integrated in the same lamp. Different modes can be switched through intelligent control. The lamp is connected to a remote control system to achieve centralized management and automatic adjustment. In terms of light source supply, high-brightness and low-power-consumption LED light sources are adopted to improve energy efficiency. In terms of the waterproof and dustproof design of the traffic light structure, waterproof, dustproof and corrosion-resistant materials are used to adapt to the outdoor environment and improve durability. Moreover, the top cover is connected to the installation connecting arm through a rotating disk, allowing the irradiation angle to be adjusted to adapt to different road conditions.

[0060] A multi-functional low-position traffic light of the present utility model realizes the function integration of conventional guardrail lighting, road / tunnel warning lights and fog lights in foggy days, reducing the number of lamps and construction costs. Intelligent control is achieved by setting sensors and controllers in the road traffic lamp device, which can automatically adjust the working mode according to environmental conditions and weather conditions, improving the lighting effect and driving safety. The light source module adopts high-brightness and low-power-consumption LED light sources and an intelligent control system, effectively reducing energy consumption and operating costs. The lamp structure and materials adopt a reasonable heat dissipation and protection structure design, ensuring the stability and safety of the lamp and extending its service life.

[0061] In summary, the present utility model effectively overcomes various disadvantages in the prior art and has high industrial utilization value.
