Description

Technical Field

[0001] The present invention relates to lighting component technology, and in particular to an energy-saving lighting device and system suitable for use in tunnels. Background Art

[0002] Tunnels are engineering structures buried in the ground and are a form of human use of underground space. Tunnels can be divided into traffic tunnels, hydraulic tunnels, municipal tunnels and mining tunnels. Tunnel lights are one of the common equipment in tunnels. Tunnel lights are special lamps used for tunnel lighting to solve the "black hole effect" or "white hole effect" caused by sudden changes in brightness when vehicles enter or exit the tunnel. As a type of tunnel equipment, road lighting plays an important role in ensuring tunnel driving safety.

[0003] However, according to current market research, when the LED lamp beads in commonly used tunnel lights on the market fail during use, it is still difficult for operators to replace the LED lamp beads. The maintenance convenience of the lighting lamps is low, and the influencing factors of tunnel light brightness adjustment are single, and there are few adjustment methods. When the tunnel light adjustment measures fail, the tunnel lights will be unable to adjust the brightness. When a vehicle enters the tunnel, the light inside the tunnel will affect the driver's vision, which can easily lead to traffic accidents.

DETAILED DESCRIPTION

[0034] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0035] Example 1:

At the same time, the telescopic rod is composed of two cylinders and a round rod. The inner walls of the two cylinders are slidably connected to the outer surfaces of both ends of the round rod. The ends of the two cylinders that are away from each other are respectively connected to the wall and the base 1, and the connections are fixed by screws;

[0037] The limiting component 2 is assembled in the inner cavity of the base 1, and the bottom end of the limiting component 2 is connected to the top end of the connecting component 11. The limiting component 2 is used to fix the lighting device;

[0038] The limiting component 2 includes a bottom plate 21 connected to the base 1, a connecting member 22 is provided at the top of the bottom plate 21, and a support column 23 is rotatably installed at the top of the connecting member 22. At the same time, a positioning member 24 is installed at the end of the support column 23 away from the connecting member 22, wherein the support column 23 supports the positioning member 24, and the positioning member 24 is used to limit the side of the lighting device and adjust the angle of the lighting device. A protective member 25 is provided at the top of the positioning member 24, and the protective member 25 supports the positioning member 24;

[0039] The positioning member 24 includes a support plate 26 connected to the support column 23. A limit shaft 27 is rotatably mounted on one side of the support plate 26, and an elastic member 28 is rotatably mounted on the outer surface of the limit shaft 27. The elastic member 28 is a torsion spring or other elastic device. A movable plate 29 is mounted on the end of the limit shaft 27 away from the support plate 26. One end of the elastic member 28 is connected to the support plate 26, and the other end is connected to the movable plate 29. When the support plate 26 is subjected to force, the elastic member 28 supports the movable plate 29 and presses the support plate 26 tightly against the lighting device.

[0040] A positioning shaft 31 is provided on one side of the support plate 26 and at one end away from the limiting shaft 27.

The outer surface of the positioning shaft 31 at the end away from the support plate 26 is slidably connected to the inner wall of the arc-shaped groove 32. When the movable plate 29 rotates around the positioning shaft 31, the backing plate 44 first moves downward to the longest position of the arc-shaped groove 32, and then the elastic member 28 is squeezed by the movable plate 29. After the movable plate 29 squeezes the elastic member 28, the lighting device is limited by the force of the elastic member 28.

[0041] The protective member 25 includes an extension plate 33 rotatably connected to the limit shaft 27.

A screw 37 is threadedly installed on the inner wall of the threaded slot 36, and a clamping member 38 is provided at one end of the screw 37, and a nut 39 is rotatably installed at the other end; a fixing member 35 is rotatably installed on one side of the connecting member 22. The clamping column 41 has an elastic mechanism 42 sleeved on its outer surface. A clamping block 43 is rotatably mounted on the outer surface of the clamping column 41. One end of the elastic mechanism 42 is connected to the clamping block 43, and the other end is connected to the clamping column 41. A backing plate 44 is mounted on the opposite end of the two movable plates 29, and a protrusion 45 corresponding to the clamping block 43 is provided at the bottom end of the backing plate 44. At the same time, a second hole 46 is opened on the end of the clamping block 43 away from the backing plate 44, which is in contact with the connecting member 22. The radius of the second hole 46 is larger than the radius of the connecting member 22.

[0042] When the lighting device is placed on the backing plate 44, the movable plates 29 provided at both ends of the backing plate 44 rotate downward. Since the other ends of the movable plates 29 are connected to the baffle 34, the baffle 34 moves closer to the outer surface of the lighting device until the baffle 34 fits the outer surface of the lighting device and fixes the lighting device.

[0043] The two connecting members 22 are rotatably mounted with connecting plates at opposite ends, and the two connecting plates are rotatably connected at opposite ends through the rotating plate. At the same time, the end of the rotating plate away from the connecting plate passes through and extends to the outside of the base 1 and is connected to the top of the connecting assembly 11, so that the angle of the entire lighting device can be adjusted by pressing the base 1; at the same time, the clamping component 38 includes a retractable support plate, and the support plate is composed of a cylinder and a round rod. The outer surface of the round rod is provided with an adjustment block, and the outer surface of the cylinder is provided with a slot corresponding to the adjustment block. The inner wall of the slot is slidably connected to the outer surface of the adjustment block, and the outer surface of the round rod is slidably connected to the inner wall of the cylinder. A spring plate is provided at one end of the round rod and located in the inner cavity of the cylinder, and the elastic plate is composed of an elastic device such as a spring, so that when the support plate supports the lighting device, the support plate is supported by the elastic plate, and the lighting device is further fixed. At the same time, the angle of the light of the lighting device is adjusted by adjusting the elastic plates at both ends of the support plate, thereby adapting to the light at the tunnel entrance.

[0044] Example 2:

[0045] See also Figure 7-Figure 8 This embodiment provides a technical solution based on the first embodiment: the clamping component 38 includes an adjustment column 51 connected to the screw 37, one end of the adjustment column 51 is fixedly connected to the output end of the driving member, that is, when the driving member is activated, the adjustment column 51 can be driven to rotate. The driving member includes but is not limited to a stepping motor or a servo motor. A ring 52 is rotatably mounted on the outer surface of the adjustment column 51, and a wave groove 53 is formed on the inner wall of the ring 52, wherein the wave groove 53 is wavy. At the same time, a slider 54 is provided on the outer surface of the adjustment column 51 to fit the wave groove 53;

[0046] When the slider 54 fits with the inner wall of the wave groove 53, the adjusting column 51 is rotated to adjust the position of the ring 52 on the adjusting column 51; the inner cavity of the ring 52 is provided with a plurality of support blocks 55, and they are evenly distributed in the inner cavity of the ring 52, one end of the support block 55 is installed with a moving part 56, and the end of the moving part 56 away from the support block 55 is provided with an elastic component 57, which is a device with power output such as a spring, and at the same time, the end of the elastic component 57 away from the moving part 56 is connected to the inner wall of the ring 52, and a slide groove 58 is provided inside the ring 52 and below the elastic component 57. The inner wall of the slide groove 58 is in contact with the inner wall of the moving part 56. The outer surface is slidably connected, an adjusting rod 59 is rotatably installed on the top of the moving part 56, and a pillar 61 is rotatably installed in the middle position of the adjusting rod 59. At the same time, the end of the pillar 61 away from the adjusting rod 59 is rotatably connected to the inner wall of the ring 52, and the end of the adjusting rod 59 away from the moving part 56 is rotatably installed with a clamping member 62. The arc surface of the ring 52 is provided with a through hole 63 corresponding to the clamping member 62, and the outer surface of the clamping member 62 is slidably connected to the inner wall of the through hole 63. Both sides of the base 1 are provided with a hole 64 corresponding to the clamping member 62, and the holes 64 are evenly distributed inside the base 1. The outer surface of the clamping member 62 fits with the inner wall of the hole 64;

[0047] When the ring 52 moves, the clip 62 slidably mounted on the ring 52 is engaged with a hole 64 provided on the inner wall of the base 1. At the same time, the radius of the sliding connection portion between the inner wall of the base 1 and the ring 52 gradually decreases. Therefore, when the clip 62 is docked with the hole 64, the whole is in a fixed state. When the fixation is cancelled, the ring 52 is rotated. Since a sliding track is provided on the inner wall of the hole 64 in a counterclockwise direction, the clip 62 is separated from the hole 64 through the sliding track, thereby facilitating the adjustment of the angle of the lighting device.

[0048] Example 3:

[0049] An energy-saving lighting system suitable for use in tunnels, which is suitable for the above-mentioned energy-saving lighting device suitable for use in tunnels, and includes a processing controller, an external monitoring feedback unit, and a lighting dimming unit;

[0050] An external monitoring feedback unit is installed at the tunnel entrance and outside the tunnel and is used to monitor the brightness information, color temperature information and incoming vehicle data outside the tunnel, and transmit the monitored external tunnel information data to the processing controller;

[0051] The external monitoring feedback unit includes a photosensor, a color temperature sensor, a vehicle speed sensor and a monitoring controller outside the tunnel. The output ends of the photosensor, color temperature sensor and vehicle speed sensor are all connected to the input end of the monitoring controller outside the tunnel. The vehicle speed sensor collects the traffic volume and vehicle speed. The monitoring controller outside the tunnel is communicated with the processing controller. There are at least two color temperature sensors, which are respectively arranged outside the tunnel and at the entrance of the tunnel. The photosensor, color temperature sensor, vehicle speed sensor and monitoring controller outside the tunnel are all common knowledge in the field and are directly applied without replacement. Therefore, they will not be described in detail. Through the setting of the external monitoring feedback unit, the light environment outside the tunnel and real-time incoming vehicle information can be monitored, which is conducive to the processing controller to ensure that the lighting device can be accurately controlled;

[0052] A processing controller is used to receive information data transmitted by the external monitoring feedback unit and perform calculations to obtain the minimum lighting brightness and required lighting color temperature required in the tunnel. Then, based on the data transmitted by the photosensor and the color temperature sensor, it is determined whether the light brightness and color temperature need to be adjusted. The processing controller outputs lighting control instructions and the required brightness and color temperature values to the lighting dimming unit based on the calculation results to control the operation of the lighting device. At the same time, the processing controller can also synchronously control the start of the driving member and drive the adjustment column 51 to rotate, thereby adjusting the light angle inside the tunnel to make it suitable for the light during the current lane driving process. The processing controller is a single-chip microcomputer in this field, including but not limited to an SMC62 single-chip microcomputer or an HT45F0060 single-chip microcomputer;

[0053] The lighting dimming unit is used to receive the lighting control instructions and the brightness and color temperature values required to be adjusted output by the processing controller, and adjust the lighting device to the brightness and color temperature values preset by the processing controller according to the instructions. The lighting dimming unit adopts the existing dimming lighting circuit technology and the lighting device's own adjustable brightness and color temperature properties to achieve this. It belongs to the existing technology and will not be elaborated here. It enables the lighting device to effectively reduce lighting energy consumption and is beneficial to environmental protection. At the same time, the system is currently only used in two-way two-lane tunnels.

[0054] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims.
