Description

Technical Field

[0001] The present application belongs to the field of tunnel brightness adjustment, and specifically relates to a tunnel lighting energy-saving system using a tunnel sunshade and adjustable angle lamps. Background Art

[0002] Tunnel shading sheds are installed at the entrances and exits of tunnels to reduce the contrast between light and dark after entering the tunnel, ease visual adaptation time, improve driving safety, and also protect lighting facilities.

[0003] Tunnel lighting energy saving refers to the use of sensors to sense ambient light intensity, vehicle driving conditions, human activity and other conditions, and automatically adjust the brightness, color and mode of lighting. Real-time monitoring of energy consumption can minimize energy consumption.

[0004] However, current tunnel lighting energy saving is not the optimal solution: it only considers the reduction of energy consumption, and does not fully utilize the high-intensity lighting resources at the tunnel entrance.

[0005] Therefore, there is a need for tunnel lighting that utilizes tunnel sunshades and adjustable angle lamps, combined with intelligent lighting control and natural light sensing, to achieve refined management of tunnel lighting.

[0006] Existing related technologies include a Chinese invention patent with patent application number CN201710018230.4 and titled "Tunnel entrance section lighting system", which discloses: a tunnel entrance section lighting system, comprising a light shielding shed (1), a light guide device (2), a reflector (3) and an in-tunnel light distribution system (4), wherein the light shielding shed is located in the direction of the extension line of the highway outside the tunnel entrance, the light guide device is embedded and installed on the top of the light shielding shed, the reflector is arranged directly below the light guide device, and the in-tunnel light distribution system is arranged on the top of the tunnel (5). The reflector reflects the outgoing light after passing through the light guide device to the in-tunnel light distribution system located at the tunnel vault, and the in-tunnel light distribution system distributes light energy on the tunnel wall and the ground as needed to achieve tunnel lighting.

[0007] Another example is the Chinese invention patent application number CN201811444083.8, entitled "Highway Tunnel Portal Dimming System Based on Equivalent Lighting", which discloses: A highway tunnel portal dimming system based on equivalent lighting provided by the present invention comprises a sunshade shed arranged at the portal and an auxiliary dimming subsystem arranged at the portal; the sunshade shed comprises arc-shaped ribs, longitudinal beams and a ceiling, the ribs are arranged in a length direction perpendicular to the extension direction of the tunnel, and the longitudinal beams are parallel to the extension direction of the tunnel; the sunshade shed is divided into N sections from the direction away from the portal to the direction close to the portal, the spacing between adjacent ribs in the same section is equal, and the spacing between ribs in different sections gradually decreases from the end away from the portal to the end close to the portal; the auxiliary dimming subsystem comprises a lighting device arranged on the top outside the sunshade shed, a light-scattering device arranged in the transition section of the tunnel, a detection unit for detecting tunnel parameters, and a controller unit.

[0008] The above two patents mainly achieve light transmission through a sunshade, and collect sunlight through a lighting device, and then irradiate the sunlight into the tunnel entrance to achieve brightness adjustment of the tunnel entrance. However, in actual applications, the sunlight irradiation angle at the tunnel entrance changes with different time periods every day, which causes the length of the sunlight irradiated on the ground through the sunshade to change, while the angle of the reflected light structure in the above two patents is fixed, that is, it can only collect sunlight and irradiate it to the ground inside the tunnel entrance at a fixed angle, and it is impossible to adjust the reflection angle according to the light intensity of the ground. Even if the reflection angle can be adjusted, its practicality is insufficient, and it is impossible to achieve a natural transition to solve the change of light intensity outside the tunnel entrance. Moreover, when there is no sunlight at night, the lighting equipment in the above comparative documents needs an external power supply to achieve lighting, which does not meet the energy-saving requirements.

[0038] The dimming controller is connected to the signal of the passive solar light guide and the angle-adjustable tunnel energy-saving lamp, and adjusts the brightness of the passive solar light guide and the angle-adjustable tunnel energy-saving lamp while controlling the light reflection angle of the passive solar light guide and the angle-adjustable tunnel energy-saving lamp.

[0039] Further, The tunnel entrance reinforcement section includes reinforcement section 1 and reinforcement section 2; The transition section includes transition section 1 and transition section 2; The exit lighting section includes exit 1 section and exit 2 section; Reinforcement Section 1 is located at the entrance of the tunnel and extends into the tunnel, the first section of Reinforcement Section 2 is adjacent to the last section of Reinforcement Section 1, the first section of Transition Section 1 is adjacent to the last section of Reinforcement Section 1, the first section of Transition Section 2 is adjacent to the last section of Transition Section 1, Exit Section 2 is located at the exit of the tunnel and extends into the tunnel, and the last section of Exit Section 1 is adjacent to the first section of Exit Section 2.

[0040] When the real-time brightness outside the tunnel is greater than the brightness of the tunnel entrance reinforcement section: the brightness of the tunnel entrance reinforcement section lighting group and the transition section reinforcement lighting group is calculated according to the principle of gradual decrease. The calculation formula is as follows: L th1 = k ×L 20 (S) L th2 =0.5× k ×L 20 (S) L tr1 =0.15× L th1 L tr2 =0.05× L th1 In the formula, L th1 To enhance the brightness of the first stage, L th2 To enhance the 2-stage lighting brightness, L tr1 To transition 1 stage of lighting brightness, L tr2 To transition between 2 levels of lighting brightness; L 20 (S) is the real-time brightness outside the tunnel. The brightness of each section inside the tunnel is calculated in real time based on the brightness outside the tunnel. k is the brightness reduction coefficient of the entrance section, ranging from 0.01 to 0.07; The brightness of the exit lighting section lighting group is: L ex1 =3× L in L ex2 =5× L in in, L ex1 The lighting brightness of the exit is 1 level. L ex2 2 levels of lighting brightness for the exit, L in The lighting brightness in the middle of the tunnel is the lighting throughout the tunnel to ensure driving safety. The exit lighting section lighting group is installed at the entrance to adapt to the brightness difference inside and outside the tunnel. The value and determination of the lighting brightness in the middle of the tunnel are the existing technologies in this field.

[0041] The dimming controller adopts a stepless dimming strategy for passive solar light guides and angle-adjustable tunnel energy-saving lamps. Stepless dimming means that the brightness of passive solar light guides and angle-adjustable tunnel energy-saving lamps is graded and dimmed according to the brightness outside the tunnel, and the control grade is not less than 100, so as not to have adverse effects on drivers. It is also to avoid the impact of instantaneous fast frame control on the life of lamps and power supplies. The specific strategies are as follows: P n = L n × L 20 (S) / L 20 Where: P n is the brightness of the dimming control level of each lighting segment in the tunnel, n represents the specific level number, L n Indicates the design brightness of each lighting segment. L 20 (S) is the real-time brightness outside the tunnel, L 20 To design the brightness outside the cave.

[0042] The principle of dimming controller controlling the light reflection angle of passive solar light guide and angle-adjustable tunnel energy-saving lamps is: For the tunnel entrance reinforcement section in D th1 To strengthen the length of 1 section,D th2 To strengthen the 2nd segment, D s To illuminate the parking sight distance, h is the clearance height in the tunnel, L 20 (S) is the real-time brightness outside the tunnel, L 20 To design the brightness outside the tunnel; the sight distance for illuminated parking is common knowledge in this field and will not be elaborated here. The length of the enhanced section 1 is consistent with the length of the light irradiated on the road surface in the tunnel by a corresponding group of tunnel entrance enhanced section lighting groups, and the length of the enhanced section 2 is consistent with the length of the light irradiated on the road surface in the tunnel by a corresponding group of tunnel entrance enhanced section lighting groups, that is, the length of different groups of tunnel entrance enhanced section lighting groups irradiating the ground is the length of different tunnel entrance enhanced sections.

[0043] Strengthen the lighting group for the transition section in, D tr1 is the length of transition 1, D tr2 is the length of transition 2, v t is the design speed of the tunnel; the length of transition section 1 is consistent with the length of light irradiated on the road surface in the tunnel by a corresponding set of transition section enhanced lighting groups, and the length of transition section 2 is consistent with the length of light irradiated on the road surface in the tunnel by a corresponding set of transition section enhanced lighting groups, that is to say, the length of light irradiated on the ground by different sets of transition section enhanced lighting groups is the length of different transition sections.

[0044] For exit lighting segment The length of exit 1 section and exit 2 section is designed to be 25 meters to 35 meters. The length of exit 1 section is consistent with the length of light emitted by a corresponding group of exit lighting sections on the road surface in the tunnel, and the length of exit 2 section is consistent with the length of light emitted by a corresponding group of exit lighting sections on the road surface in the tunnel, that is, the length of light emitted by different groups of exit lighting sections on the ground is the length of different exit lighting sections.

[0045] During the day, when there is sunlight, the solar energy storage module uses sufficient solar energy to store electricity. At the same time, the sunlight shines through the transparent plate to the back of the Fresnel lens. The sunlight passes through the Fresnel lens to form a parallel beam and projected to the tunnel entrance reinforcement section. The tunnel entrance reinforcement section is a section close to the outside of the tunnel, in order to reduce the brightness difference between the inside and outside of the tunnel to accommodate drivers to enter the tunnel safely.

[0046] At night, when there is no natural sunlight, the energy stored by the sunlight during the day is sufficient. According to the current environment, the light source can be turned on, and the light source is emitted parallel to the Fresnel lens parallel to the lamp bead board to the adjustable reflective structure, achieving the same effect as when the sunlight is shining during the day.

[0047] The micro motor drives the folding and telescopic device to move as required to adjust the angle of the reflected light. The micro motor is opened or closed by the instruction of the dimming controller. The specific transmission method of the instruction information here belongs to the application of the existing technology and will not be repeated here.

[0048] In multiple passive solar light guides and angle-adjustable tunnel energy-saving lamps, the lower end of the Fresnel lens is connected to the movable end of the folding and telescopic device. When the folding and telescopic device is adjusted, the lower end of the Fresnel lens moves with the slider, changing the angle between the Fresnel lens and the horizontal plane, and the parallel light beam projected to the ground area through the lens changes. The background can directly issue instructions to adjust the angle. As a functional extension, other lighting equipment in the tunnel can also be linked at the same time to ensure that when there are more clouds or the sun is low, when the sun is insufficient, and when both lighting methods cannot work properly, the tunnel lighting effect can still work normally to ensure driving safety.

The calculation formula is as follows: L th1 = k ×L 20 (S) L th2 =0.5× k ×L 20 (S) L tr1 =0.15× L th1 L tr2 =0.05× L th1 In the formula, L th1 To enhance the brightness of the first stage, Lth2 To enhance the 2-stage lighting brightness, L tr1 To transition 1 stage of lighting brightness, L tr2 To transition between 2 levels of lighting brightness; L 20 (S) is the real-time brightness outside the tunnel. The brightness of each section inside the tunnel is calculated in real time based on the brightness outside the tunnel. k is the brightness reduction coefficient of the entrance section, ranging from 0.01 to 0.07; The brightness of the exit lighting section lighting group is: L ex1 =3× L in L ex2 =5× L in in, L ex1 The lighting brightness of the exit is 1 level.

[0053] The dimming controller adopts a stepless dimming strategy for passive solar light guides and angle-adjustable tunnel energy-saving lamps. Stepless dimming means that the brightness of passive solar light guides and angle-adjustable tunnel energy-saving lamps is graded and dimmed according to the brightness outside the tunnel, and the control grade is not less than 100, so as not to have adverse effects on drivers. It is also to avoid the impact of instantaneous fast frame control on the life of lamps and power supplies. The specific strategies are as follows: P n = L n × L 20 (S) / L 20 Where: P n is the brightness of the dimming control level of each lighting segment in the tunnel, n represents the specific level number, L n Indicates the design brightness of each lighting segment.

The solar energy storage structure and the sunlight reflection structure are installed on the bracket, and the sunlight reflection structure is located in front of the solar energy storage structure. The solar energy storage structure includes a solar panel 10 and a battery 9, and the solar panel 10 is connected to the battery 9. The sunlight reflection structure includes a folding and telescopic device 5 for adjusting the light reflection route by changing the lens angle.

[0058] The solar energy storage structure also includes a PCB board 8 and an LED lighting board 11. The PCB board 8 is connected to the battery 9 and the LED lighting board 11 respectively, and the solar panel 10 is connected to the battery 9. After receiving sunlight, the solar panel 10 transfers energy to the battery 9 for storage. The battery 9 transmits electrical energy to the LED lighting board 11 through the PCB board 8, thereby providing lighting for the lamp.

[0059] The solar panel 10 is placed flat on the top of the bracket, the battery 9 and the PCB board 8 are both located inside the bracket, and the lamp beads of the LED lighting board 11 are located between the solar energy storage structure and the direct sunlight reflection structure, and are perpendicular to the solar panel 10. The purpose of the LED lighting board 11 being perpendicular to the solar panel 10 is to be able to obliquely irradiate light into the tunnel. There are multiple lamp beads on the LED lighting board 11, and the irradiation direction of each lamp bead is consistent. The PCB board 8 is a circuit board known to those skilled in the art that can control the battery 9 to power the LED lighting board 11, and the specific model is not limited by this patent.

[0060] The sunlight reflection structure comprises a transparent plate 1, a first Fresnel lens 3, a second Fresnel lens 12 and a folding and telescopic device 5, wherein the transparent plate 1 is located at the top and exposed to the bracket, the first Fresnel lens 3 is arranged in parallel with the LED lighting plate 11, and completely covers the front end of the lamp bead; the second Fresnel lens 12 is located at the front end of the sunlight reflection structure, the upper end of the second Fresnel lens 12 is connected to the front end of the transparent plate 1 through the first connecting structure 2, and the lower end of the second Fresnel lens 12 is connected to the moving end of the folding and telescopic device 5 through the second connecting structure 4, and the sunlight is reflected from the upper end of the transparent plate 1. The sunlight is irradiated from the front side into the interior of the sunlight reflection structure, and is reflected by the second Fresnel lens 12 to the first Fresnel lens 3, and then refracted to the outside of the lamp by the first Fresnel lens 3. The light from the lamp beads on the LED lighting board 11 located behind the second Fresnel lens 12 after being energized is also transmitted to the first Fresnel lens 3 through the second Fresnel lens 12, and then refracted to the outside of the lamp. The moving end of the folding and telescopic device 5 is connected to the lower end of the first Fresnel lens 3, driving the inclination angle of the first Fresnel lens 3 to change, thereby adjusting the angle of the emitted light.

[0061] The first connection structure 2 is a hinged structure.

[0062] The folding and telescopic device 5 includes a micro motor 7 and a threaded rod connected to the output end of the micro motor 7. The second connecting structure 4 is provided with an internal thread and is sleeved on the threaded rod. The second connecting structure 4 can be a structure that converts rotational motion into linear motion in the art. For example, the second connecting structure 4 can be driven to move forward and backward in its threaded section by a shell, a bearing, an internal thread and other structures when the threaded rod rotates forward and backward. This will not be described in detail here.

[0063] The micro motor 7 is connected to the PCB board 8 and the battery 9 respectively. The battery 9 supplies power to the micro motor 7, and the PCB board 8 controls the forward rotation, reverse rotation or shutdown of the micro motor 7. The function of the PCB board 8 belongs to the well-known technology of those skilled in the art, and does not belong to the invention of this application.

[0064] The bottom of the first Fresnel lens 3 is hinged to one end of the bottom plate 6 which is horizontally arranged, and a fixing frame is arranged at the bottom of the second Fresnel lens 12, and the other end of the bottom plate 6 passes through the fixing frame and is placed in the fixing frame. The bottom plate 6 can achieve the effect of sealing the space between the two lenses, and when the bottom of the first Fresnel lens 3 is driven by the threaded rod to move forward or backward, the bottom plate 6 is also driven to move forward and backward horizontally. Since one end of the bottom plate 6 is hinged to the first Fresnel lens 3 and the other end is placed in the fixing frame, the bottom plate 6 can be kept in a horizontal state without changing whether it moves forward or backward.

[0065] During the day, when there is sunlight, the solar energy storage module uses sufficient solar energy to store electricity. At the same time, the sunlight shines through the transparent plate to the back of the Fresnel lens. The sunlight passes through the Fresnel lens to form a parallel beam and projected to the tunnel entrance reinforcement section. The tunnel entrance reinforcement section is a section close to the outside of the tunnel, in order to reduce the brightness difference between the inside and outside of the tunnel to accommodate drivers to enter the tunnel safely.

[0066] At night, when there is no natural sunlight, the energy stored by the sunlight during the day is sufficient. According to the current environment, the light source can be turned on, and the light source is emitted parallel to the Fresnel lens parallel to the lamp bead board to the adjustable reflective structure, achieving the same effect as when the sunlight is shining during the day.

[0067] The micro motor drives the folding and telescopic device to move as required to adjust the angle of the reflected light. The micro motor is opened or closed by the instruction of the dimming controller. The specific transmission method of the instruction information here belongs to the application of the existing technology and will not be repeated here.

[0068] In multiple passive solar light guides and angle-adjustable tunnel energy-saving lamps, the lower end of the Fresnel lens is connected to the movable end of the folding and telescopic device. When the folding and telescopic device is adjusted, the lower end of the Fresnel lens moves with the slider, changing the angle between the Fresnel lens and the horizontal plane, and the parallel light beam projected onto the ground area through the lens changes. The background can directly issue instructions to adjust the angle. As a functional extension, other lighting equipment in the tunnel can also be linked at the same time to ensure that when there are more clouds or the sun is low, when the sun is insufficient, and when both lighting methods cannot work properly, the tunnel lighting effect can still work normally to ensure driving safety.

[0069] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Any simple modification or equivalent change made to the above embodiment based on the technical essence of the present invention shall fall within the protection scope of the present invention.
