[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0032] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.
[0033] like Figure 1 As shown, Figure 1 (a) is a tunnel section design, including: tunnel 1, lighting fixtures 2, cement-based self-luminous pavement 3, tunnel sidewall 4, Figure 1 (b) is the three-dimensional layout model of the tunnel. Figure 1 (c) is the layout model of self-luminous materials on the tunnel pavement (blue area). Figure 1(d) is a model of the layout position of lighting fixtures. This embodiment proposes a tunnel energy-saving lighting system combining a self-luminous pavement with lighting fixtures, including: a tunnel self-luminous pavement, a plurality of sensing devices, a plurality of lighting devices and a control module;
[0034] A lighting device, used for lighting the tunnel 1;
[0035] The tunnel self-luminous pavement is used to absorb and store the light energy of the lighting device, and emit light in an environment without light source;
[0036] A sensor device for detecting the brightness in the tunnel 1 and the brightness of the tunnel's self-luminous road surface;
[0037] The control module is used to control the switch of the lighting device according to the light intensity in the tunnel 1.
[0038] Specifically, the tunnel energy-saving lighting system combining self-luminous pavement and lighting lamps proposed in this embodiment includes a full-section cement-based self-luminous pavement 3 of the tunnel, multiple sensors and multiple lighting lamps, and multiple sensors (illuminance detectors) and lighting lamps are respectively arranged in each section of the tunnel.
[0039] Furthermore, the road surface adopts an asphalt road with cement-based self-luminous material as the injection slurry.
[0040] The cement-based self-luminous material is made of aluminate fluorescent powder, reflective glass beads and white cement, and the material is poured into porous asphalt concrete to form a cement-based self-luminous pavement 3.
[0041] Specifically, in this embodiment, the cement-based self-luminous pavement 3, the road inside the tunnel adopts an asphalt road with cement-based self-luminous material as the slurry poured into it, and the road surface can absorb and store light, and can emit light in the absence of a light source.
[0042] The self-luminous road uses cement-based self-luminous materials as asphalt roads. The cement-based self-luminous materials are composed of aluminate phosphors (SrAl2O4:Eu 2+ ,Dy 3+ ), reflective glass beads and white cement, and the materials are poured into porous asphalt concrete to form a cement-based self-luminous pavement 3. The pavement can glow after being stimulated by external light sources and maintain afterglow for a period of time.
[0043] Furthermore, the lighting device uses a photosensitive automatic dimming LED lamp, which is installed above the tunnel, and the constant current driving source of the lighting fixture 2 has a PWM dimming control interface.
[0044] Specifically, in this embodiment, the lighting fixture 2 uses a photosensitive automatic dimming LED lamp, which is installed above the tunnel, and ensures that the constant current driving source of the lighting fixture 2 has a PWM dimming control interface. It is used to realize tunnel lighting and provide illumination for the self-luminous road surface, and can be adjusted according to the light intensity inside the tunnel.
[0045] Sensors are used to monitor light intensity, including road luminous intensity and lighting fixture 2 light intensity.
[0046] The sensing device adopts a light intensity detector.
[0047] Further, the control module includes: a first control unit and a second control unit;
[0048] A first control unit, configured to control the lighting device to turn off when the luminous brightness of the self-luminous road surface of the tunnel detected by the sensor device reaches a first preset value;
[0049] The second control unit is used to control the brightness of the lighting device to gradually increase when the luminous brightness of the self-luminous road surface of the tunnel detected by the sensor device reaches a second preset value, so that the brightness inside the tunnel is maintained at the first preset value.
[0050] Specifically, in this embodiment, Figure 2 As shown, the entire section of the tunnel is made of asphalt road with cement-based self-luminous material as the slurry. Lighting lamps and sensors are installed in each section, and the switches of each lighting lamp and each lamp in the tunnel are automatically controlled by sensors (illuminance detectors). The tunnel is first illuminated by lighting lamps. During the normal operation of the lighting lamps, the self-luminous road surface absorbs and stores the light energy generated by the lighting lamps. After the lighting lamps have been working for 6 to 8 hours, the sensors inside the tunnel can detect that the luminous intensity of the self-luminous road surface reaches 100lx. At this time, the sensor controls the switch of the lighting lamp inside the tunnel to turn off, and the cement-based self-luminous road surface 3 plays a role to achieve lighting. Since the luminous intensity of the self-luminous road surface will gradually decrease with the increase of time, when the sensor detects that the luminous intensity of the road surface is less than 3.2cd / m 2 When the light is turned off, the modulator controls the lighting to gradually increase its brightness, so that the brightness of the entire tunnel is maintained at around 100lx, avoiding sudden brightness increase or decrease. Until the lighting comes into play again, the entire tunnel energy-saving lighting system enters a cycle.
[0051] The present embodiment provides a tunnel energy-saving lighting system that combines a self-luminous pavement with a lighting lamp. The cement-based self-luminous pavement inside the tunnel absorbs and stores the light during the working period of the lighting lamp. Under the premise of meeting the national traffic safety lighting standards, the working time of the lighting fixtures is greatly reduced to achieve the purpose of energy saving and emission reduction. At the same time, the cement-based self-luminous material has a long afterglow time, which can provide lighting for vehicles inside the tunnel in the event of a sudden power outage to ensure driving safety. At the same time, the luminous pavement guides the driver's sight.
[0052] This embodiment also proposes a tunnel energy-saving lighting method combining a self-luminous road surface with a lighting lamp, including:
[0053] Use cement-based self-luminous materials to prepare tunnel self-luminous pavement;
[0054] Install lighting and sensor devices at preset locations in the tunnel;
[0055] The sensor device is used to detect the brightness in the tunnel and the brightness of the tunnel's self-luminous road surface, and the brightness inside the tunnel is maintained at a first preset value by controlling the switch of the lighting device.
[0056] Further, controlling the switch of the lighting device so that the brightness inside the tunnel is maintained at a first preset value includes:
[0057] Detecting the illuminance in the tunnel and the luminous brightness of the tunnel's self-luminous pavement, and when the luminous brightness of the tunnel's self-luminous pavement detected by the sensor device reaches a first preset value, controlling the lighting device to turn off;
[0058] When the luminous brightness of the self-luminous road surface of the tunnel detected by the sensor device reaches a second preset value, the brightness of the lighting device is controlled to gradually increase so that the brightness inside the tunnel is maintained at the first preset value.
[0059] Specifically, in this embodiment, the lighting fixture uses a photosensitive automatic dimming LED lamp, which is installed above the tunnel, and ensures that the constant current drive source of the lighting fixture has a PWM dimming control interface. It is used to achieve tunnel lighting and provide illumination for the self-luminous road surface, and can be adjusted according to the light intensity inside the tunnel.
[0060] Sensors are used to monitor light intensity, including road luminous intensity and lighting intensity. The sensing device uses a light intensity detector.
[0061] The self-luminous road uses cement-based self-luminous materials as asphalt roads. The cement-based self-luminous materials are composed of aluminate phosphors (SrAl2O4:Eu 2+ ,Dy 3+), reflective glass beads and white cement, and the materials are poured into porous asphalt concrete to form a cement-based self-luminous pavement. The pavement can glow after being stimulated by external light sources and maintain afterglow for a period of time.
[0062] The entire section of the tunnel is made of asphalt road with cement-based self-luminous material as the slurry. Lighting lamps and sensors are set in each section. The switches of each lighting lamp and each lamp in the tunnel are automatically controlled by sensors (illuminance detectors). The tunnel is first illuminated by lighting lamps. During the normal operation of the lighting lamps, the self-luminous pavement absorbs and stores the light energy generated by the lighting lamps. After the lighting lamps have been working for 6 to 8 hours, the sensors inside the tunnel can detect that the luminous intensity of the self-luminous pavement reaches 100lx. At this time, the sensor controls the switch of the lighting lamp inside the tunnel to turn off, and the cement-based self-luminous pavement plays a role to achieve lighting. Since the luminous intensity of the self-luminous pavement will gradually decrease with the increase of time, when the sensor detects that the luminous intensity of the pavement is insufficient, the modulator controls the brightness of the lighting lamp to gradually increase, so that the brightness of the entire tunnel is maintained at around 100lx, avoiding sudden increase or decrease in brightness. Until the lighting works again, the entire tunnel energy-saving lighting system enters a cycle.
[0063] The embodiments described above are only descriptions of the preferred embodiments of the present invention and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary technicians in this field should all fall within the protection scope determined by the claims of the present invention.
