Description
Technical Field
[0001] The present invention relates to the technical field of sensors, and in particular to a movable solar intelligent control lighting beacon. Background Art
[0002] A photosensitive sensor generally refers to a device that can sensitively sense light energy from ultraviolet light to infrared light and convert the light energy into an electrical signal.
[0003] A photosensitive sensor is a sensing device mainly composed of photosensitive elements, which are mainly divided into four categories: ambient light sensors, infrared light sensors, sunlight sensors, and ultraviolet light sensors, and are mainly applied in fields such as automotive body electronics applications and intelligent lighting systems. Modern electrical measurement technology is becoming increasingly mature. Due to its advantages such as high precision and being convenient to be connected to a microcomputer for automatic real-time processing, it has been widely used in the measurement of electrical and non-electrical quantities. However, the electrical measurement method is easily interfered. When performing AC measurement, the frequency response is not wide enough and there are certain requirements for voltage withstand and insulation. Today, with the rapid development of laser technology, the above problems can be solved.
[0004] Under the existing technology, street lamps and beacons usually need to obtain the photosensitive value through a photosensitive sensor to control automatic turning on at night and automatic turning off during the day. However, some beacons with high brightness are likely to irradiate the photosensitive sensor, resulting in incorrect triggering of the photosensitive sensor and repeated turning off and starting of the beacon. Summary of the Invention
[0005] To solve the problem that under the existing technology, street lamps and beacons usually need to be automatically turned on at night and turned off during the day through a photosensitive sensor, but some beacons with high brightness are likely to irradiate the photosensitive sensor, resulting in incorrect triggering of the photosensitive sensor and repeated turning off and starting of the beacon, the present application provides a movable solar intelligent control lighting beacon.
[0006] A movable solar intelligent control lighting beacon includes a photosensitive element and also includes a photosensitive internal thread. The photosensitive internal thread is arranged in a tubular shape. The photosensitive element is arranged at one end of the photosensitive internal thread, and a photosensitive external thread is arranged at the other end of the photosensitive internal thread. The photosensitive external thread is sleeved on the photosensitive internal thread. A glass sheet is arranged between the photosensitive external thread and the photosensitive internal thread. A light passing hole is arranged on the photosensitive external thread. The glass sheet allows the light source to pass through. A black film is arranged on the side of the glass sheet close to the photosensitive element, and the black film is fixedly connected to the glass sheet. The length of the photosensitive internal thread is greater than or equal to 100 mm and less than or equal to 202 mm.
[0007] By adopting the above technical solution, by setting a photosensitive internal thread and a photosensitive external thread, light can enter the photosensitive internal thread and then be recognized by the photosensitive element after a certain distance. Increasing the light incident distance can effectively filter out the diffuse reflected light. During the day, the intensity of the diffuse reflected light is relatively high, and it can pass through the photosensitive internal thread and be sensed by the photosensitive element whether it is cloudy or sunny, so the beacon will not be activated during the day. When the beacon is turned on at night, when the light incident distance is long, the diffuse reflected light can be filtered out. At this time, the intensity of the diffuse reflected light is weak, and the photosensitive value after filtering is relatively low. Therefore, it is difficult for the photosensitive element to be affected by the beacon at night, reducing the situation where the beacon is continuously turned on and off due to the influence of the beacon on the photosensitive element.
[0008] Optionally, the diameter of the light passing hole is greater than or equal to 1 mm and less than or equal to 33 mm.
[0009] By adopting the above technical solution, with a smaller light passing diameter, it is more difficult for the diffuse reflected light to enter the photosensitive internal thread through the light passing hole and be recognized by the photosensitive element, further reducing the influence of the beacon on the diffuse reflected light. At the same time, more thresholds can be left for the photosensitive element to recognize the photosensitive value, improving the setting space for the beacon to set the photosensitive value switch.
[0010] Optionally, the length of the photosensitive internal thread is greater than or equal to 55 mm and less than or equal to 150 mm. By adopting the above technical solution, when the length of the photosensitive internal thread is too short, the diffuse reflected light is more likely to enter the photosensitive internal thread and be sensed by the photosensitive element. Therefore, when the length of the photosensitive internal thread is between 55 mm and 150 mm, the diffuse reflected light will neither directly be sensed by the photosensitive element nor easily form diffuse reflection inside the photosensitive internal thread to cause the photosensitive element to form a perception, which can further reduce the influence of the beacon on the photosensitive element when it is started at night.
[0011] Optionally, the length of the photosensitive internal thread is 55 mm.
[0012] By adopting the above technical solution, through experiments, under the same other conditions, when the length of the photosensitive internal thread is 55 mm, the photosensitive value sensed by the photosensitive element at night is near the lowest value. Therefore, setting the length of the photosensitive internal thread to 55 mm can further reduce the situation where the beacon affects the photosensitive element when it is turned on at night, and further improve the accuracy of the beacon's opening and closing.
[0013] Optionally, the diameter of the light passing hole is greater than or equal to 2.5 mm and less than or equal to 5 mm.
[0014] By adopting the above technical solutions, through experiments, when other conditions are the same, when the diameter of the light passing hole is between 2.5 mm and 5 mm, the photosensitive value sensed by the photosensitive element at night is near the lowest value. Therefore, setting the diameter of the light passing hole between 2.5 mm and 5 mm can further reduce the influence on the photosensitive element when the lighthouse is turned on at night, and further improve the accuracy of the lighthouse opening and closing.
[0015] Optionally, the diameter of the light passing hole is 2.5 mm.
[0016] By adopting the above technical solutions, through further experiments, when other conditions are the same, when the diameter of the light passing hole is 2.5 mm, the photosensitive value sensed by the photosensitive element at night is near the lowest value. Therefore, setting the diameter of the light passing hole at 2.5 mm can further reduce the influence on the photosensitive element when the lighthouse is turned on at night, and further improve the accuracy of the lighthouse opening and closing.
[0017] Optionally, a threaded section is provided on the photosensitive external thread, and the threaded section is used to connect to the lighthouse.
[0018] By adopting the above technical solutions, by providing a threaded section on the photosensitive external thread, it is more convenient to install the photosensitive sensor on the lighthouse, and the convenience of installation is further improved.
[0019] Optionally, a limiting pad is further provided on the photosensitive external thread, and the limiting pad is used to abut against the outer wall of the lighthouse.
[0020] By adopting the above technical solutions, when the photosensitive sensor is installed on the lighthouse, the limiting pad can form friction with the outer wall of the lighthouse, thereby restricting the displacement of the photosensitive sensor, and thus reducing the loosening of the photosensitive sensor and improving the stability of the photosensitive sensor.
[0021] Optionally, a hexagonal thin nut is further provided on the threaded section of the photosensitive external thread, and the hexagonal thin nut is used to abut against the inner wall of the lighthouse.
[0022] By adopting the above technical solutions, the hexagonal thin nut can cooperate with the limiting pad after installation to clamp the tower wall of the lighthouse, further restricting the displacement of the photosensitive sensor, and thus further reducing the loosening of the photosensitive sensor and further improving the stability of the photosensitive sensor.
[0023] In summary, the present application has at least the following beneficial effects: 1. This application solves the problem that existing street lights and lighthouses usually need to be automatically turned on at night and automatically turned off during the day through photosensitive sensors. However, some lighthouses with high brightness are likely to shine on the photosensitive sensors, resulting in incorrect triggering of the photosensitive sensors and repeated turning off and starting of the lighthouses. By setting the photosensitive internal thread and the photosensitive external thread, this application forms a light inlet path of a certain length in the photosensitive sensor and opens corresponding light inlet holes, so that the photosensitive value sensed by the photosensitive element at night when the lighthouse emits light is reduced, reducing the situation where the photosensitive element receives a signal to turn off the lighthouse due to too high a photosensitive value when the lighthouse starts, resulting in repeated start and stop of the lighthouse.
[0024] 2. This application further limits the length of the photosensitive internal thread, that is, the light inlet distance, and also limits the diameter of the light inlet hole on the photosensitive external thread, which can further reduce the photosensitive value sensed by the photosensitive element when the lighthouse shines at night, thereby further reducing the photosensitive element Brief Description of the Drawings

[0030] The following further details this application through specific embodiments in conjunction with the drawings.
[0031] Embodiment 1 A movable solar intelligent control lighting lighthouse, as shown in Figure 1 and Figure 2As shown, it includes a tower body 5 and a photosensitive element 11. In specific implementation, a lamp post 51 is provided on the tower body 5, and a lamp head 511 is provided at the top of the lamp post 51. The lamp head 511 is rotatably connected to the lamp post 51 and is driven by a motor to rotate. After the lamp head 511 is powered on, it can provide illumination. Wheels 52 are provided at the bottom of the tower body 5. A hitch head 53 for hitching a vehicle is also provided on the tower body 5. The tower body 5 can be hitched and pulled by a vehicle. A support leg 55 is also provided at the bottom of the tower body 5. The support leg 55 is slidably connected to the tower body 5 and its position can be fixed by bolts. When moving, the support leg 55 is retracted, and when fixed, the support leg 55 jacks up the entire tower body 5 to complete the fixation of the position of the tower body 5, thereby improving the convenience of movement. A solar bracket 54 is also provided on the tower body 5. The solar bracket 54 is connected to the lamp head 511 to supply power to the lamp head 511. The photosensitive element 11 is installed on the side wall of the tower body 5.
[0032] As Figure 2 and Figure 3 shown, it further includes a photosensitive internal thread 1. The photosensitive internal thread 1 is tubular. The photosensitive element 11 is provided at one end of the photosensitive internal thread 1. A photosensitive external thread 2 is provided at the other end of the photosensitive internal thread 1. The photosensitive external thread 2 is sleeved on the photosensitive internal thread 1. A glass sheet 3 is provided between the photosensitive external thread 2 and the photosensitive internal thread 1. A light passing hole 23 is provided on the photosensitive external thread 2. The glass sheet 3 allows the light source to pass through. A black film 31 is provided on the side of the glass sheet 3 close to the photosensitive element 11. The black film 31 is fixedly connected to the glass sheet 3. The length of the photosensitive internal thread 1 is greater than or equal to 100 mm and less than or equal to 202 mm. The diameter of the light passing hole 23 is greater than or equal to 1 mm and less than or equal to 33 mm. In specific implementation, different light inlet hole diameters were tested on sunny and cloudy days and the data in Table 1 was obtained. From Table 1, it can be concluded that during the day on sunny days, the light inlet distance and the diameter of the light inlet hole have little effect on the photosensitive value. However, at night on sunny days, the light inlet distance and the diameter of the light inlet hole have a significant effect on the photosensitive value, which can effectively reduce the photosensitive value sensed by the photosensitive element 11 at night. On cloudy days, the photosensitive value during the day is relatively lower, and the photosensitive value at night is also lower. Therefore, setting the light inlet distance formed by the photosensitive external thread 2 and the photosensitive internal thread 1 and using the light inlet hole for light inlet can effectively reduce the misjudgment of the photosensitive element 11 caused by the diffuse reflected light of the lighthouse at night and affect the control of the lighthouse.
[0033] As Figure 2 and Figure 3As shown in the figure, a threaded section 21 is provided on the photosensitive external thread 2, and the threaded section 21 is used to connect to the lighthouse. A limit pad 22 is also provided on the photosensitive external thread 2, and the limit pad 22 is used to abut against the outer wall of the lighthouse. A hexagonal thin nut 211 is further provided on the threaded section 21 of the photosensitive external thread 2, and the hexagonal thin nut 211 is used to abut against the inner wall of the lighthouse. In specific implementation, the photosensitive external thread 2 can be directly connected to the lighthouse by means of threaded connection, and at the same time, the inner wall of the lighthouse is clamped by the hexagonal thin nut 211 inside the lighthouse, so as to limit the displacement of the photosensor and reduce the situation of shaking and loosening of the photosensor, and further increase the stability of the photosensor during use.
[0034] Working principle: The photosensitive internal thread 1 and the photosensitive external thread 2 are provided to form a light inlet passage of a certain length in the photosensor, and corresponding light inlet holes are opened, so that the photosensitive value sensed by the photosensitive element 11 at night when the lighthouse emits light is reduced, and the situation that the lighthouse repeatedly starts and stops because the photosensitive value is too high when the lighthouse starts and the photosensitive element 11 obtains a signal to turn off the lighthouse is reduced.
[0035] Table 1 Embodiment 2 The main difference between Embodiment 2 and Embodiment 1 is that the length of the photosensitive internal thread 1 in Embodiment 2 is greater than or equal to 55 mm and less than or equal to 150 mm. In specific implementation, in combination with Table 1 and Table 2, when the length of the photosensitive internal thread 1 is greater than or equal to 55 mm and less than or equal to 150 mm, that is, when the light inlet distance is also in the range of 55 mm to 150 mm, the photosensitive value at night is significantly reduced compared with when the light inlet distance is too small or too large. Therefore, when the length of the photosensitive internal thread 1 is greater than or equal to 55 mm and less than or equal to 150 mm, the filtering effect on the diffused reflected light at night can be further enhanced, and the situation of misjudgment on the photosensitive element 11 when the lighthouse starts at night can be further reduced.
[0036] Working principle: The basic working principle is the same as that of Embodiment 1, but on the basis of Embodiment 1, the diameter of the light inlet hole and the light inlet distance are further optimized, and the filtering effect on the diffused reflected light of the lighthouse at night is further improved, thereby further increasing the accuracy of judging start and stop at night.
[0037] Table 2 Embodiment 3 The main difference between the third embodiment and the second embodiment is that the length of the photosensitive internal thread 1 in the third embodiment is 55 mm. During specific implementation, referring to Table 2 and Table 3, it can be known that when the diameter of the light inlet hole is 5 mm and the light inlet distance is 55 mm, the photosensitive value sensed by the photosensitive element 11 at night is significantly less than that when the light inlet distance is 100 mm. When the light inlet distance is 55 mm, the photosensitive sensor has a better filtering effect on the diffuse reflected light at night. Therefore, choosing the photosensitive internal thread 1 with a length of 55 mm can further improve the filtering effect on the diffuse reflected light when the lighthouse starts, and further reduce the misjudgment situation of the photosensitive element 11 at night.
[0038] Working principle: The basic working principle is the same as that of the second embodiment, but on the basis of the second embodiment, the diameter of the light inlet hole and the light inlet distance are further optimized, further improving the filtering effect on the diffuse reflected light of the lighthouse at night, thereby further increasing the accuracy of judging start and stop at night.
[0039] Table 3 The fourth embodiment The main difference between the fourth embodiment and the third embodiment is that the length of the photosensitive internal thread 1 in the third embodiment, that is, the diameter of the light passing hole 23, is greater than or equal to 2.5 mm and less than or equal to 5 mm. During specific implementation, referring to Table 3 and Table 4, it can be known that when the light inlet distance is 55 mm, the photosensitive value when the diameter of the light inlet hole is 2.5 mm is significantly less than that when the diameter of the light inlet hole is 5 mm. Therefore, when the diameter of the light inlet hole is 2.5 mm, the photosensitive sensor has a better filtering effect on the diffuse reflected light at night. Therefore, choosing the diameter of the light inlet hole of 2.5 mm can further improve the filtering effect on the diffuse reflected light when the lighthouse starts, and further reduce the misjudgment situation of the photosensitive element 11 at night.
[0040] Working principle: The basic working principle is the same as that of the third embodiment, but on the basis of the third embodiment, the diameter of the light inlet hole and the light inlet distance are further optimized, further improving the filtering effect on the diffuse reflected light of the lighthouse at night, thereby further increasing the accuracy of judging start and stop at night.
[0041] Table 4 The fifth embodiment The main difference between the fifth embodiment and the fourth embodiment lies in the length of the photosensitive internal thread 1 in the fourth embodiment, that is, the diameter of the light passing hole 23 is 2.5 mm. During specific implementation, referring to Table 1, Table 4, and Table 5, when the light incident distance is 55 mm and the diameter of the light incident hole is 2.5 mm, the photosensitive value at night is significantly lower than other situations. Therefore, when the light incident distance is 55 mm and the diameter of the light incident hole is 2.5 mm, the photosensitive value sensed by the photosensitive element 11 for the lighthouse at night is near the lowest value. Working principle: The basic working principle is the same as that of the fourth embodiment, but on the basis of the fourth embodiment, the diameter of the light incident hole and the light incident distance are further optimized, further improving the filtering effect on the diffuse reflected light of the lighthouse at night, thereby further increasing the accuracy of judging start and stop at night.
[0042] Table 5 The Sixth Embodiment As Figure 4 shown, the main difference between the sixth embodiment and the first embodiment is that a thermal expansion and contraction ring 4 is provided at the photosensitive external thread 2 in the sixth embodiment. The thermal expansion and contraction ring 4 is arranged at the position of the light incident hole. The thermal expansion and contraction ring 4 surrounds the light incident hole and cannot completely block the light incident hole. During specific implementation, during the daytime on a sunny day, as the temperature rises, the thermal expansion and contraction ring 4 will expand, reducing the diameter of the light incident hole, reducing the situation where diffuse reflected light enters the photosensitive internal thread 1 and causes long-term irradiation, and reducing the situation where the temperature of the photosensitive element 11 rises and is damaged due to long-term irradiation, further improving the service life. At night on a sunny day, as the temperature drops, the thermal expansion and contraction ring 4 will expand again, leaving the light passing hole 23 unblocked, enabling the diffuse reflected light of the lighthouse to enter normally, ensuring the normal opening state of the lighthouse, and reducing the situation where the light cannot enter at all and causes an abnormal photosensitive value judgment and a program error. When it is cloudy, due to the relatively low temperature, the diameter of the light incident hole can be increased to a certain extent, reducing the situation of misjudgment caused by too little light incident during the daytime.
[0043] Working principle: The basic working principle is the same as that of the first embodiment, but a thermal expansion and contraction ring 4 that can automatically judge the light incident demand according to weather and time is added. It can reduce the diameter of the light incident hole during the daytime and increase the diameter of the light incident hole at night, thereby further improving the accuracy of judgment.
[0044] The above are the preferred embodiments of the present application. The protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
