Description

Technical Field

[0001] The present invention relates to the technical field of smart classrooms, and in particular to an eye protection lamp for lighting smart classrooms. Background Art

[0002] A smart classroom is a typical materialization of a smart learning environment and a high-end form of multimedia and network classrooms. It is a new type of classroom built with the help of Internet of Things technology, cloud computing technology and intelligent technology. This new type of classroom includes tangible physical space and intangible digital space. It uses various intelligent equipment to assist in the presentation of teaching content, facilitate the acquisition of learning resources, promote classroom interaction, and realize situational awareness and environmental management functions. The smart classroom aims to provide a humane and intelligent interactive space for teaching activities; through the combination of physical space and digital space, and the combination of local and remote, it improves the relationship between people and the learning environment, realizes the natural interaction between people and the environment in the learning space, and promotes personalized learning, open learning and ubiquitous learning.

[0003] According to the difference in external light intensity during the day and at night, the light intensity in the smart classroom needs to be adjusted to achieve the purpose of eye protection. However, the brightness of the lamps used in the existing smart classrooms cannot be adjusted adaptively. The lamps are hung on the ceiling at a fixed height, which makes it inconvenient to clean, maintain and replace the lamps. The existing lamps can only emit white light and cannot choose warm or cool light according to changes in the external environment. The functionality is poor. More importantly, the existing lamps are generally hung directly above the students' desks, which makes it easy for light to directly enter the students' eyes. When there is too high brightness or too large a brightness contrast in the field of vision, students will feel glare, affecting visibility. Therefore, in response to the above problems, an eye protection lamp for smart classroom lighting is proposed here. Summary of the invention

[0004] In order to overcome the above-mentioned technical problems, an object of the present invention is to provide an eye protection lamp for smart classroom lighting.

[0005] The purpose of the present invention can be achieved through the following technical solutions:

[0006] An eye protection lamp for smart classroom lighting comprises a lampshade and two LED light boards arranged inside the lampshade, wherein the lampshade is designed in a trapezoidal structure and is suspended on the classroom ceiling through an electric telescopic rod above the lampshade, and the inner cavity of the lampshade is also provided with a light sensor for detecting external lighting conditions and automatically adjusting the light intensity of the LED light board, the two LED light boards are symmetrically arranged at an angle of 45° with respect to the vertical center plane of the lampshade, and the inclination angle of the two LED light boards can be automatically adjusted within a range of plus or minus 15°, and the light-emitting surface of the LED light board is also provided with a plurality of RGB light strips.

[0007] Furthermore, a top plate is provided on the top surface of the lampshade, and the two are detachably connected via four studs at the end corners of the lampshade, and two opposite short side walls of the lampshade are provided with strip-shaped through holes for heat dissipation.

[0008] Furthermore, both sides of the top surface of the top plate are fixedly connected to the output end of the electric telescopic rod.

[0009] Furthermore, a motor and a bidirectional screw rod vertically arranged with respect to the output end of the motor are arranged in the middle part of the inner cavity of the lampshade, the motor is fixedly connected to the bottom surface of the inner cavity of the lampshade through a fixing block at its bottom end, and a first bevel gear is also sleeved and fixed on the output end of the motor, the bidirectional screw rod is installed on the bottom surface of the inner cavity of the lampshade through connecting seats on both sides thereof, two second bevel gears are arranged on the outer wall of the bidirectional screw rod near the position of the first bevel gear, the two second bevel gears are both meshed with the first bevel gear and the two second bevel gears are arranged in mirror symmetry, and connecting ears are screwed together at both ends of the bidirectional screw rod.

[0010] Furthermore, round rods are provided at both ends of the LED lamp board, and the round rods are rotatably connected to the inner cavity wall of the lampshade through bearings. An oblique groove is provided on the oblique wall of the LED light board corresponding to the position of the connecting ear. The oblique groove has a triangular structure and its two opposite inner walls are provided with mirror-symmetrical strip grooves, and the two strip grooves are set at a 45° angle with respect to the bottom surface of the oblique groove.

[0011] Furthermore, a sliding rod is movably connected between the two strip-shaped grooves, and the sliding rod is rotatably sleeved with the bottom end of the connecting ear.

[0027] The following will be combined with 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.

[0028] like Figure 1 The figure shows the overall structure schematic diagram of an eye protection lamp for smart classroom lighting in the present invention. Compared with traditional classroom lamps, the eye protection lamp can not only adjust the height from the ground, but also the color of the light source it emits can be changed according to needs. Moreover, by changing the position of the lampshade 2 in the classroom, the probability of glare and high-contrast astigmatism can be reduced, thereby protecting students' eyesight safety and having a higher degree of safety.

[0029] like Figure 1 and Figure 2 As shown, an eye protection lamp for smart classroom lighting includes a lampshade 2 and two LED light panels 5 arranged inside the lampshade 2. The lampshade 2 is designed in a trapezoidal structure, and the lampshade 2 is suspended on the classroom ceiling through an electric telescopic rod 1 above it. The inner cavity of the lampshade 2 is also provided with a light sensor 3 for detecting external lighting conditions and automatically adjusting the light intensity of the LED light panels 5. The two LED light panels 5 are symmetrically arranged at an angle of 45° with respect to the vertical center plane of the lampshade 2, and the inclination angle of the two LED light panels 5 can be automatically adjusted within a range of plus or minus 15°, as shown in FIG. Figure 8 As shown, the light-emitting surface of the LED light board 5 is also provided with a plurality of RGB light strips 56 .

[0030] Based on the above technical solution, a light sensor 3 electrically connected to the LED light board 5 is installed in the lampshade 2. When the lighting conditions outside the classroom change, the light sensor 3 can automatically adjust the output brightness of the LED light board 5, saving energy while also protecting the students' eyesight safety in a timely manner. By using the electric telescopic rod 1 to drive the lampshade 2 to rise and fall, it is not only convenient for daily cleaning of the lampshade 2, but also convenient for maintenance and repair when the lampshade 2 fails. The multiple strip through holes 23 opened on the lampshade 2 can also prevent the LED light board 5 from overheating and malfunctioning, thereby ensuring its long-term use. Moreover, by installing the lampshade 2 in the aisle between adjacent desks in the classroom The LED light board 5 is preferably configured to prevent the light source of the LED light board 5 from directly shining into the students' eyes, so that the desks can be illuminated from the side or both sides, and the lighting effect is better. According to the size of the smart classroom and the distance between the aisle and the desk, the inclination angle of the LED light board 5 is adjusted to make the light of the LED light board 5 enter from both sides of the human eye, avoiding direct radiation, reducing glare, and protecting the students' eyesight health. By arranging an RGB light strip 56 on the light-emitting surface of the LED light board 5, the color temperature of the LED light board 5 can be adjusted, so that the smart classroom can select light of different color temperatures in different environments, which not only protects the students' eyesight but also facilitates the adjustment of the learning atmosphere in the classroom, thereby improving the learning efficiency of the users.

[0031] like Figure 3 As shown, the top surface of the lampshade 2 is provided with a top plate 21, and the two are detachably connected through four studs 22 at the end corners of the lampshade 2. The two opposite short side walls of the lampshade 2 are provided with strip-shaped through holes 23 for heat dissipation, as shown in FIG. Figure 2 As shown, both sides of the top surface of the top plate 21 are fixedly connected to the output end of the electric telescopic rod 1. Starting the electric telescopic rod 1 can drive the lampshade 2 to rise or fall. When the inside of the lampshade 2 needs to be inspected, the inside of the lampshade 2 can be directly inspected by unscrewing the four studs 22, which is more convenient.

[0032] like Figure 4 and Figure 5As shown, a motor 4 and a bidirectional screw 44 vertically arranged with respect to the output end of the motor are arranged in the middle of the inner cavity of the lampshade 2, the motor 4 is fixedly connected to the inner cavity bottom surface of the lampshade 2 through a fixing block 41 at its bottom end, and a first bevel gear 42 is also sleeved and fixed on the output end of the motor 4, the bidirectional screw 44 is installed on the inner cavity bottom surface of the lampshade 2 through connecting seats 45 on both sides thereof, two second bevel gears 43 are arranged on the outer wall of the bidirectional screw 44 near the first bevel gear 42, the two second bevel gears 43 are both meshed with the first bevel gear 42 and the two are mirror-symmetrical, and connecting ears 46 are screwed together at both ends of the bidirectional screw 44. When the inclination angle of the LED light board 5 needs to be adjusted, the motor 4 is started, and the output end of the motor 4 drives the first bevel gear 42 to rotate, and the two second bevel gears 43 meshing with the first bevel gear 42 drive the bidirectional screw rod 44 to rotate. As the bidirectional screw rod 44 rotates, the two connecting ears 46 screwed together with the bidirectional screw rod 44 move toward the two ends of the bidirectional screw rod 44 respectively, and as the connecting ears 46 move, the LED light board 5 rotates accordingly.

[0033] like Figure 6 As shown, both ends of the LED lamp board 5 are provided with round rods 51, and the round rods 51 are rotatably connected to the inner cavity wall of the lampshade 2 through bearings 52, as shown in FIG. Figure 7 As shown, the inclined wall of the LED light board 5 is provided with an inclined groove 53 at the position corresponding to the connecting ear 46. The inclined groove 53 is a triangular structure and the two opposite inner walls thereof are provided with mirror-symmetrical strip grooves 54. The two strip grooves 54 are arranged at a 45° angle with respect to the bottom surface of the inclined groove 53. A slide bar 55 is also movably connected between the two strip grooves 54, and the slide bar 55 is rotatably sleeved with the bottom end of the connecting ear 46. When the connecting ear 46 moves, the slide bar 55 rotatably sleeved with the connecting ear 46 moves synchronously along the strip groove 54. In this process, the force applied by the slide bar 55 to the LED light board 5 drives the LED light board 5 to rotate about the bearing 52, thereby realizing the change of the inclination angle of the LED light board 5. When the light source of the LED light board 5 just enters from both sides of the student's field of vision, the adjustment of the angle of the LED light board 5 is stopped.
