Description

Technical Field

[0001] This utility model relates to the field of lighting device technology, specifically to a smart classroom lighting device based on the Internet of Things. Background Technology

[0002] The Internet of Things (IoT)-based smart classroom lighting system utilizes IoT technology to automate, optimize energy consumption, and intelligently manage classroom lighting through sensors, controllers, and communication modules. Its core lies in dynamically adjusting classroom light brightness, color temperature, and on / off status via environmental sensing, data analysis, and remote control technologies. This meets the lighting needs of teachers and students while reducing energy consumption and improving management efficiency. It integrates light sensors (for real-time monitoring of natural light intensity), infrared human body sensors (for detecting human activity), temperature and humidity sensors (for assisting environmental adjustment), and smart meters (for monitoring electricity consumption), forming a multi-dimensional data acquisition system. The smart classroom lighting system uses LED lamps, saving over 60% more energy than traditional lighting. Combined with the use of natural light, energy consumption can be further reduced. For example, one university saw annual electricity cost savings exceeding 30% after deployment.

[0003] In existing technologies, traditional classroom lighting devices are mostly installed at fixed angles, and the direction of the lighting devices cannot be adjusted according to the light and dark scenes in the classroom. This may result in insufficient brightness in the podium area or desk area due to diffused light. Utility Model Content

[0004] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a smart classroom lighting device based on the Internet of Things, which can effectively solve the problems mentioned in the background technology.

[0005] To achieve the above objectives, this utility model provides the following technical solution: This utility model provides a smart classroom lighting device based on the Internet of Things, including a housing and an LED lighting body disposed on the inner wall of the housing. The top of the housing is fixedly installed at both ends, and an adjustment component is provided at the upper end of the fixed plate. The adjustment component is used to adjust the angle of the classroom lighting LED lamp. The adjustment assembly includes a first arc-shaped base plate and a second arc-shaped base plate. The lower ends of both the first and second arc-shaped base plates are fixedly mounted on the upper end of the fixed plate. Arc-shaped guide rail grooves are formed inside both the first and second arc-shaped base plates. Electric motors are fixedly connected to the lower outer sides of both the first and second arc-shaped base plates. Furthermore, a first arc-shaped guide rail plate and a second arc-shaped guide rail plate are respectively fixedly installed on the upper ends of the first arc-shaped base plate and the second arc-shaped base plate. The interior of the first arc-shaped guide rail plate and the second arc-shaped guide rail plate are both provided with through openings, and the upper end of the through openings is provided with track grooves.

[0006] Furthermore, a first arc-shaped toothed rod and a second arc-shaped toothed rod are slidably sleeved on the inner wall of the track groove, and a first bearing sleeve is fixedly installed on the inner side of both the first arc-shaped toothed rod and the second arc-shaped toothed rod. A hanging rod is fixedly sleeved inside the first bearing sleeve, and a fastener is fixedly connected to the upper end of the hanging rod.

[0007] Furthermore, a shaft is fixedly installed at the lower end of the first and second arc-shaped toothed rods, and a second bearing sleeve is fixedly sleeved on the outer side of the shaft.

[0008] Furthermore, a roller is slidably fitted inside the arc-shaped guide rail groove, and a second bearing sleeve is fixedly fitted onto the inner wall of the roller.

[0009] Furthermore, a gear is meshed with one side of the first and second arc-shaped racks, and an electric motor is fixedly mounted on the lower end of the gear. A fixing plate passes through the outer side of the output shaft of the electric motor, and the output shaft of the electric motor is fixedly connected to the lower end of the gear. One end of the fixing plate is fixedly connected to the outer side of the first and second arc-shaped guide rails, respectively. The upper end of the electric motor is fixedly connected to the lower end of the fixing plate, and the lower end of the electric motor is fixedly mounted on the upper end of the mounting plate.

[0010] The technical solution provided by this utility model has the following advantages compared with the known prior art: 1. This utility model, through the adjustment components, the meshing transmission of gears and arc-shaped racks, and the sliding guidance of rollers in the arc-shaped guide rail groove, enables the LED lighting body to achieve angle deflection adjustment, controlling the lighting equipment to project light onto specific areas of the classroom. During class, the lighting equipment can focus light on the podium area, enhancing the clarity of the teacher and blackboard writing. Adjusting the angle allows the light to evenly cover the entire desk area, improving the targeting and comfort of lighting in different teaching scenarios, and avoiding insufficient brightness in the podium or desk area due to diffused light.

[0011] 2. Simultaneously, the rollers, in conjunction with the arc-shaped guide rail groove, arc-shaped guide rail plate, and arc-shaped base plate, ensure the LED lighting equipment remains stable during angle adjustment. Combined with the limiting function of the track groove, this prevents the LED lighting equipment from shifting outside the arc-shaped guide rail plate and arc-shaped base plate and falling off under slight external force.

[0015] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0016] The present invention will be further described below with reference to the embodiments. Example 1:

[0017] Reference Figures 1 to 4This first embodiment of the present invention discloses an IoT-based intelligent classroom lighting device, including a housing 1 and an LED lighting body 5 disposed on the inner wall of the housing 1. Fixing plates 3 are fixedly installed at both ends of the top of the housing 1, and adjustment components 6 are provided on the upper end of the fixing plates 3. The adjustment components 6 are used to adjust the angle of the classroom lighting LED lamps. This IoT-based intelligent classroom lighting device is a new type of lighting system that integrates IoT technology, sensing technology, LED lighting technology, and intelligent control algorithms. Its core function is to sense the classroom environment (such as personnel activity and light intensity) and receive remote control commands to realize automatic switching, brightness adjustment, and angle adjustment of LED lighting, achieving energy-saving, convenient, and personalized lighting effects. Simultaneously, it can be centrally monitored and managed through an IoT platform. The intelligent classroom lighting device is a common technological means in daily life and will not be described in detail here. The adjustment assembly 6 includes a first arc-shaped base plate 61 and a second arc-shaped base plate 62. The lower ends of both the first arc-shaped base plate 61 and the second arc-shaped base plate 62 are fixedly mounted on the upper end of the fixed plate 3. Arc-shaped guide rail grooves 611 are formed inside both the first arc-shaped base plate 61 and the second arc-shaped base plate 62. Electric motors 64 are fixedly connected to the lower outer sides of both the first arc-shaped base plate 61 and the second arc-shaped base plate 62. A first arc-shaped guide rail plate 65 and a second arc-shaped guide rail plate 66 are fixedly mounted on the upper ends of the first arc-shaped base plate 61 and the second arc-shaped base plate 62, respectively. The plates 66 are fixed together to form a closed structure. Both the first arc-shaped guide plate 65 and the second arc-shaped guide plate 66 have through openings 610. The through openings 610 are arc-shaped and provide an angular rotation trajectory with the track groove 617. The upper end of the through opening 610 is provided with the track groove 617. The inner wall of the track groove 617 is slidably fitted with a first arc-shaped toothed rod 67 and a second arc-shaped toothed rod 68. The first arc-shaped toothed rod 67 and the second arc-shaped toothed rod 68 can rotate angularly within the track groove 617, but the rotation angles of the first arc-shaped toothed rod 67 and the second arc-shaped toothed rod 68 are opposite in direction. For example, refer to... Figure 3The first arc-shaped gear 67 rotates to the left, while the second arc-shaped gear 68 rotates to the right, adjusting the angle of the LED lighting body 5 and the outer casing 1. First bearing sleeves 69 are fixedly installed on the inner sides of both the first and second arc-shaped gears 67 and 68. When the first and second arc-shaped gears 67 and 68 rotate, the hanger 2, fixedly connected to the inner ring of the first bearing sleeve 69, rotates within its outer ring, while the hanger 2 remains stationary. An internally fixed suspension rod 2 is attached, and a fastener 4 is fixedly connected to the upper end of the suspension rod 2. The outer shell 1 and the LED lighting body 5 are suspended from the ceiling of the classroom by the fastener 4. The first arc-shaped toothed rod 67 and the second arc-shaped toothed rod 68 are slidably sleeved inside the first arc-shaped guide plate 65 and the second arc-shaped guide plate 66. The first arc-shaped toothed rod 67 and the second arc-shaped toothed rod 68, the first arc-shaped guide plate 65 and the second arc-shaped guide plate 66 are nested together, forming a support structure between the LED lighting body 5, the outer shell 1 and the suspension rod 2. Example 2:

[0018] Reference Figures 3 to 4 This is the second embodiment of the present invention, which differs from the first embodiment in that: a shaft 614 is fixedly installed at the lower end of the first arc-shaped toothed rod 67 and the second arc-shaped toothed rod 68, and a second bearing sleeve 613 is fixedly sleeved on the outer side of the shaft 614. When the first arc-shaped toothed rod 67 and the second arc-shaped toothed rod 68 rotate in opposite directions, the shaft 614 is further driven to rotate at an angle. A roller 612 is slidably sleeved inside the arc-shaped guide groove 611, and a second bearing sleeve 613 is fixedly sleeved on the inner wall of the roller 612. When the shaft 614 rotates at an angle, the outer side of the shaft 614 rotates inside the outer ring of the second bearing sleeve 613. The shaft 614 is fixedly sleeved on the inner ring of the second bearing sleeve 613, thereby driving the roller 612 to rotate at an angle inside the arc-shaped guide groove 611. A gear 616 is meshed with one side of 68. An electric motor 64 is fixedly mounted on the lower end of the gear 616. By driving the electric motor 64, power is transmitted to the output shaft, which in turn drives the gear 616 to rotate. The gear 616 on the first arc-shaped rack 67 rotates to the left, and the gear 616 on the second arc-shaped rack 68 rotates to the right, causing the first arc-shaped rack 67 and the second arc-shaped rack 68 to rotate in opposite directions. A fixing plate 615 passes through the outer side of the output shaft of the electric motor 64. The output shaft of the electric motor 64 is fixedly connected to the lower end of the gear 616. One end of the fixing plate 615 is fixedly connected to the outer side of the first arc-shaped guide plate 65 and the second arc-shaped guide plate 66, respectively. The upper end of the electric motor 64 is fixedly connected to the lower end of the fixing plate 615, and the lower end of the electric motor 64 is fixedly mounted on the upper end of the mounting plate 63.

[0019] The remaining structure is the same as that in Example 1.

[0020] The workflow of this utility model is as follows: First, when the lighting angle needs to be adjusted, the controller sends drive commands to two electric motors 64. These two electric motors 64 correspond to the first arc-shaped gear 67 and the second arc-shaped gear 68, respectively, and their output shafts rotate in opposite directions (e.g., the left electric motor 64 drives gear 616 to rotate clockwise, and the right electric motor 64 drives gear 616 to rotate counterclockwise). The output shafts of the electric motors 64 drive gear 616 to rotate, and gear 616 meshes with the arc-shaped gears (either the first arc-shaped gear 67 or the second arc-shaped gear 68), converting the rotational power into the arc-shaped motion of the gears. Because the two gears 616 rotate in opposite directions, the first arc-shaped gear 67 and the second arc-shaped gear 68 rotate in opposite directions along the track groove 617 (e.g., the first arc-shaped gear 67 rotates to the left, and the second arc-shaped gear 68 rotates to the right). Secondly, the rotation of the arc-shaped gear directly drives the connected outer shell 1 and the LED lighting body 5 to deflect synchronously. Because the two sets of arc-shaped gears move in opposite directions, the overall tilt angle of the lighting device can be adjusted in a specific direction, thereby adjusting the projection angle of the light from the LED lighting body 5 (such as focusing on the podium or a certain area of ​​the desk). The first arc-shaped gear 67 and the second arc-shaped gear 68 slide in the track groove 617. The arc-shaped track groove 617 and the through-hole 610 restrict the movement trajectory of the gears. At the same time, the roller 612 on the outside of the shaft 614 slides in the arc-shaped guide groove 611, further assisting the gears to move along the arc-shaped trajectory. Finally, when the lighting device reaches the preset angle, the controller stops the drive of the electric motor 64, and the meshing relationship between the gear 616 and the rack locks the rack position, thereby fixing the lighting angle.

[0021] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
