Description

Technical Field

[0001] This utility model relates to the technical field of smart LED street lighting, specifically to an LED street light with motion detection function and variable luminous efficacy. Background Technology

[0002] Smart streetlights, proposed with the concept of smart cities, are a type of lighting infrastructure adapted to modern urban construction. They effectively improve city managers' data collection and management capabilities. Existing smart streetlights primarily involve adding various electronic devices to the existing streetlights to collect on-site information, such as images and environmental data, and to communicate remotely with a management center for information transmission and remote control. However, conventional smart streetlights typically only emit white light, which can be glaring to pedestrians in the dark if the light intensity is too high. Utility Model Content

[0003] The purpose of this invention is to provide an LED street light with motion detection function and variable light efficiency that can automatically switch to soft light after detecting a pedestrian, so as to avoid glare when the pedestrian walks towards the street light.

[0004] To achieve the above objectives, the present invention provides the following technical solution:

[0005] The device includes a lampshade, a heat sink housing fixed to one side of the lampshade, a substrate fixed inside the lampshade, a number of LED beads embedded on the substrate, two rotating shafts rotatably connected inside the lampshade on both the upper and lower sides of the substrate, and a guide roller fixed to the outside of each rotating shaft. A light film rotates by friction between all the guide rollers. A connecting column is fixed to the end of the heat sink housing away from the lampshade, and a mounting rod is connected to the flange of the connecting column. A motion detection sensor is provided at the bottom of the heat sink housing, and a light intensity sensor module is fixed at the top of the heat sink housing.

[0006] Furthermore, the two ends of the rotating shaft extend out of the lamp cover, and the extended ends are rotatably connected to a rotating seat, which is fixed to the side of the lamp cover. One of the rotating shafts extends into the heat dissipation housing and is connected to a first motor. The first motor is electrically connected to a timer switch, and the timer switch is electrically connected to a motion detection sensor.

[0007] The above technical solution can drive the optical film to rotate and switch, thus achieving automatic control.

[0008] Furthermore, the light film has two colors, yellow and white, and the two colors occupy the same length.

[0009] Furthermore, the motion detection sensor includes an arc-shaped rod fixed to the bottom of the heat sink housing, with a through groove inside the arc-shaped rod, a bracket slidably connected inside the through groove, and a pyroelectric infrared sensor module fixed to the bottom of the bracket.

[0010] Using the above technical solution, the arc-shaped pole provides the travel distance for the pyroelectric infrared sensor module, which can then cyclically detect pedestrians on both sides of the street light, enabling motion detection and making it convenient to use.

[0011] Furthermore, a sliding wheel is rotatably connected to the top of the bracket, the side of the sliding wheel abuts against the inner wall of the arc-shaped rod, and a second motor is fixed to one end of the sliding wheel, the second motor being electrically connected to the base plate.

[0012] The above technical solution provides the driving force for the movement of the pyroelectric infrared sensor module.

[0013] Furthermore, the bottom of the lampshade is provided with a light-transmitting groove, and a light-concentrating plate is fixed inside the light-transmitting groove. The diameter of the light-transmitting groove is larger than the diameter of the substrate.

[0014] By adopting the above technical solution, the light concentration is improved, light dissipation is avoided, and resources are saved. In summary, the beneficial technical effects of this utility model are as follows:

[0015] 1. A light-concentrating panel is used to improve the light concentration, prevent light scattering, and save resources.

[0016] 2. The system employs a first motor and various sensor modules, which can automatically switch to soft light after detecting a pedestrian, thus avoiding glare when pedestrians walk towards the streetlight.

[0017] 3. An arc-shaped pole is adopted, which provides the travel distance for the pyroelectric infrared sensor module, allowing for cyclic detection of pedestrians on both sides of the street light. This enables motion detection and is convenient to use. Attached Figure Description

[0024] The present invention will be further described in detail below with reference to the accompanying drawings.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-4 The present invention provides a technical solution comprising: a lampshade 1, a heat dissipation housing 2 fixed on one side of the lampshade 1, a substrate 3 fixed inside the lampshade 1, a plurality of LED beads 4 embedded on the substrate 3, and rotating shafts 5 rotatably connected inside the lampshade 1 on both the upper and lower sides of the substrate 3, with two rotating shafts 5 on each side, and a guide roller 6 fixed outside each rotating shaft 5, with a light film 7 rotating between all the guide rollers 6 through friction; a connecting post 8 fixed at the end of the heat dissipation housing 2 away from the lampshade 1, and a mounting rod 9 connected to the flange of the connecting post 8; a motion detection sensor at the bottom of the heat dissipation housing 2; and a light intensity sensor module 10 fixed at the top of the heat dissipation housing 2.

[0027] The lampshade 1 has a light-transmitting groove 19 at the bottom, and a light-concentrating plate 20 is fixed inside the light-transmitting groove 19. The diameter of the light-transmitting groove 19 is larger than the diameter of the substrate 3.

[0028] Among them, the two ends of the rotating shaft 5 extend out of the lamp cover 1, and the extended ends are rotatably connected to the rotating seat 11. The rotating seat 11 is fixed on the side of the lamp cover 1. One of the rotating shafts 5 extends into the heat dissipation housing 2 and is connected to the first motor 12. The first motor 12 is electrically connected to a timer switch, and the timer switch is electrically connected to the motion detection sensor.

[0029] The first motor 12 can drive the rotating shaft 5 to rotate. When the rotating shaft 5 rotates, it drives the guide roller 6 to rotate. When all the guide rollers 6 rotate, the color of the light film 7 on the outside can be switched. In this embodiment, the light film 7 has two colors, yellow and white, and the two colors occupy the same length.

[0030] Furthermore, when the first motor 12 is driven, the white light film 7 and the yellow light film 7 can be switched to cover the light-transmitting groove 19. When the yellow light film 7 covers the light-transmitting groove 19, the light emitted by the LED beads 4 turns into yellow light after passing through the yellow light film 7.

[0031] The motion detection sensor includes an arc-shaped rod 13 fixed to the bottom of the heat sink housing 2. The arc-shaped rod 13 has a through groove 14 inside, and a bracket 15 is slidably connected inside the through groove 14. A pyroelectric infrared sensor module 16 is fixed to the bottom of the bracket 15.

[0032] A sliding wheel 17 is rotatably connected to the top of the bracket 15. The side of the sliding wheel 17 abuts against the inner wall of the arc-shaped rod 13. A second motor 18 is fixed to one end of the sliding wheel 17. The second motor 18 is electrically connected to the base plate 3.

[0033] The second motor 18 is connected to the solar panel of the street light and is powered by the solar panel. The second motor 18 can drive the sliding wheel 17 to rotate. Since the side of the sliding wheel 17 abuts against the arc rod 13, the sliding wheel 17 can slide along the inner wall of the arc rod 13 when it rotates, which drives the bracket 15 to move along the arc rod 13, and then drives the pyroelectric infrared sensor module 16 at the bottom of the bracket 15 to move on both sides of the lamp cover 1.

[0034] The second motor 18 is a servo motor, which can be set to rotate in both directions in combination with the existing motor encoder, and can realize the reciprocating movement of the sliding wheel 17.

[0035] The working principle of this utility model is as follows: The light intensity sensor module 10 is connected in series with the second motor 18. After the light intensity sensor module 10 and the second motor 18 are connected in series, the first motor 12 is connected in series with the pyroelectric infrared sensor module 16. After the light intensity sensor module 10 detects a decrease in the ambient light intensity, it excites an electrical signal, and the second motor 18 starts to work, driving the pyroelectric infrared sensor module 16 to rotate. After the pyroelectric infrared sensor module 16 detects a pedestrian, it excites an electrical signal, and the first motor 12 starts to work. At the same time, the timer switch can determine the driving time of the first motor 12 each time, so that after the light film 7 switches to the yellow light film 7, it ensures that the yellow light film 7 is completely switched within the driving time. Then, after detecting a pedestrian, it can automatically switch to soft light to avoid glare when pedestrians walk towards the street light.
