[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.
[0025] The anti-glare educational lighting fixture disclosed in this invention is mainly applied to scenarios where the existing light shield structure of lighting fixtures cannot adaptively control according to the ambient light intensity.
[0026] Reference Figures 1-8 An anti-glare educational lighting fixture, comprising:
[0027] Lampshade 3;
[0028] The bracket 1 has a base 2 bolted to its bottom. The end of the bracket 1 away from the base 2 is bolted to the upper side of the lampshade 3. A light bulb 4 is installed on the inner wall of the lampshade 3.
[0029] Connecting ring 5, the upper side of connecting ring 5 is connected to the bottom of lamp cover 3 by bolts;
[0030] Four light sensors 9 are located outside the lamp cover 3 and are distributed equidistantly in a circle.
[0031] Four light-shielding plates 8 are located outside the lampshade 3 and are distributed equidistantly in a circle. The light-shielding plates 8 are all located below the connecting ring 5.
[0032] The adaptive light control module 6 is located outside the lamp cover 3. The adaptive light control module 6 is used to enable the lamp to automatically reduce the light transmittance in a strong light environment and increase the light transmittance in a weak light environment.
[0033] Specifically, the luminaire utilizes the adaptive light control module 6 to determine the intensity or brightness of the optical fiber in the environment. This allows the luminaire to automatically reduce light transmittance and glare in strong light environments, and increase light transmittance in low light environments to ensure clear vision, thereby improving the user's viewing experience and reducing eye fatigue.
[0034] Reference Figure 3 , Figure 4 , Figure 5 and Figure 6In a preferred embodiment, the adaptive light control module 6 includes a mounting ring 601. The upper side of the mounting ring 601 is fitted to the bottom of the connecting ring 5. A fixing ring 602 is bolted to the upper side of the mounting ring 601. The fixing ring 602 is located outside the lamp cover 3. Three circumferentially distributed protrusions are bolted to the bottom of the mounting ring 601. Each protrusion is rotatably connected to a round shaft via a bearing. A light-blocking plate 603 is rotatably connected to the outside of each round shaft via a bearing. A torsion spring 604 surrounds the outside of each round shaft. One end of each torsion spring 604 is bolted to the outside of the light-blocking plate 603 on the same side, and the other end is bolted to the outside of the protrusion on the same side. The outside of each light-blocking plate 603 is bolted to... A contact rod 605 is attached; an annular pad 606 is bolted to the bottom of the mounting ring 601, and a ramp block 607 is bolted to the bottom of the annular pad 606. The outer surface of the ramp block 607 contacts the outer surface of the contact rod 605 on the same side. A rack 608 is bolted to the bottom of the annular pad 606. A circular hole is formed at the bottom of the mounting ring 601, and a motor 609 is bolted into the circular hole. The output end of the motor 609 is connected to a gear 610 via a coupling. The gear 610 meshes with the rack 608. A groove 611 is formed on the inner wall of the mounting ring 601. A fixing frame 613 is slidably connected to the inner wall of the groove 611. The fixing frame 613 is on the side opposite to the inner wall of the groove 611. Each of the four light-shielding plates 8 has a recessed hole, and a magnetic absorbing piece 614 is bolted into each recessed hole. The opposite sides of two magnetic absorbing pieces 614 on the same side are fitted together. The top inner wall of the recess 611 has three circumferentially spaced fine holes, and the top inner wall of each fine hole is bolted to a protruding rafter 616. The end of the spring 612 near the fixing frame 613 contacts the outside of the fixing frame 613. The inner wall of the fixing frame 613 is bolted to a frosted light-transmitting plate 615, and the bottom of the fixing frame 613 is bolted to three circumferentially spaced protruding rafters 616. The outside of each of the four light-shielding plates 8 is rotatably connected to the outside of the mounting ring 601 via bearings. The outside of each light-shielding plate 8 has a sliding groove 617, and the sliding groove 617 contains... A sliding block 618 is slidably connected. Each sliding block 618 is rotatably connected to a rotating seat via bearings. A lead screw 619 is rotatably connected to the upper side of one of the rotating seats via bearings. Round rods 620 are bolted to the upper sides of the other three rotating seats. The same connecting ring 622 is bolted to the upper sides of the three round rods 620. The connecting ring 622 is located outside the lampshade 3. The upper side of the lead screw 619 is rotatably connected to the bottom of the connecting ring 622 via bearings. A common annular platform 621 is provided outside the lead screw 619 and the three round rods 620. The inner wall of the annular platform 621 is bolted to the outer side of the fixed ring 602. The four light sensors 9 are all bolted to the side opposite to the fixed ring 602.A second gear 623 is externally mounted on the lead screw 619. The bottom of the second gear 623 is rotatably connected to the upper side of the annular platform 621 via a bearing. A second motor 625 is bolted to the upper side of the annular platform 621. The output end of the second motor 625 is connected to a third gear 624 via a coupling. The third gear 624 meshes with the second gear 623. A quick-connect module 7 is mounted on the connecting ring 5.
[0035] Specifically, when the light sensor 9 detects a strong light environment, motor 609 is started. Motor 609 drives gear 610 to rotate, causing rack 608 to rotate and annular pad 606 to rotate. This causes inclined block 607 to gradually push contact rod 605 along the inclined plane, allowing light-blocking plate 603 to overcome the torque of torsion spring 604 and rotate towards frosted light-transmitting plate 615, thereby increasing the degree of light blocking by light-blocking plate 603 against light emitted by bulb 4. Motor 625 is then started, driving gear 623 to rotate and mesh with gear 624. This causes lead screw 619 to rotate and descend on annular platform 621, allowing lead screw 619 and round rod 620 to push slider 618 downward on slide groove 617, causing the four light-blocking plates 8 to gradually retract inward, thereby reducing the light transmittance of the device. When the light sensor 9 detects a dim ambient light, the above steps are reversed.
[0036] In specific application scenarios, the adaptive light control module 6 is mainly used in the adaptive light control process. That is, the adaptive light control module 6 can soften the light emitted by the bulb 4 by using the frosted surface of the frosted light-transmitting plate 615 to reduce the chance of glare. The fixed frame 613 and magnetic 614 can be used to quickly replace the frosted light-transmitting plate 615. The contact rod 605 and inclined block 607 can control the light emitted by the bulb 4 and adjust the light output of the bulb 4. The slider 618, lead screw 619 and connecting ring 622 can realize the synchronous control of the light shield 8, thereby reducing manual intervention and reducing the workload of the staff.
[0037] Reference Figure 7 and Figure 8In a preferred embodiment, the quick-connect module 7 includes pins 701. The connecting ring 5 has three circumferentially equidistant slots, the inner walls of which are respectively inserted into the outer surfaces of the three pins 701. The mounting ring 601 has three circumferentially equidistant circular grooves, each containing a stabilizing seat 702 connected by bolts, with the outer surface of the pin 701 inserted into the inner wall of the stabilizing seat 702 on the same side. Each stabilizing seat 702 has three circumferentially equidistant cutting grooves 704 on its upper side, each containing a locking rod 705 slidably connected. Each pin 701 has an annular groove 703 on its outer surface, the outer surface of which engages with the inner wall of the annular groove 703 on the same side. Each locking rod 705 has a short shaft 706 bolted to its upper surface, and the pins 701... All three rotating frames 707 are slidably connected to the outside of the three rotating frames 707. The outside of the three rotating frames 707 is slidably connected to the inner wall of the circular groove on the same side. The bottom of the rotating frame 707 is rotatably connected to the upper side of the stabilizing seat 702 through bearings. The upper side of the rotating frame 707 is provided with three circumferentially distributed curved grooves 708. The inner wall of the curved grooves 708 is slidably connected to the outside of the short shaft 706 on the same side. The top inner wall of the rotating frame 707 is bolted with a coil spring 709. The end of the coil spring 709 away from the rotating frame 707 is bolted to the upper side of the stabilizing seat 702 on the same side. The outside of the pin 701 is surrounded by a return spring 710. One end of the return spring 710 is bolted to the outside of the pin 701, and the other end is bolted to the upper side of the connecting ring 5.
[0038] Specifically, when connecting the lampshade 3 to the device, the connecting ring 5 is aligned with the mounting ring 601, and the return spring 710 is pressed down to overcome its elasticity, thereby inserting the return spring 710 into the stabilizing seat 702. The rotating frame 707 is rotated to overcome the torque of the coil spring 709, so that the curved groove 708 can push the locking rod 705 connected to the short shaft 706 to slide outwards from the stabilizing seat 702. After the pin 701 is fully inserted into the stabilizing seat 702, the rotating frame 707 is released. Under the torque of the coil spring 709, the curved groove 708 pushes the locking rod 705 to quickly return to its original position, so that one end of the locking rod 705 is inserted into the annular groove 703 and locks the pin 701, thereby completing the connection between the device and the lampshade 3.
[0039] In specific application scenarios, the quick connection module 7 is mainly used for quick connection modules. That is, the quick connection module 7 can achieve the effect of quickly connecting the connecting ring 5 and the mounting ring 601 by using the annular groove 703 and the locking rod 705. The curved groove 708 and the coil spring 709 can ensure that the short shaft 706 can always maintain the locking state of the locking rod 705 and the annular groove 703, thereby avoiding the risk of the device falling off the lamp cover 3 when it is impacted, and improving safety.
[0040] Working principle: When connecting the lampshade 3 to the device, align the connecting ring 5 with the mounting ring 601, overcome the elastic force of the return spring 710 and press it down, so that the return spring 710 is inserted into the stabilizing seat 702. Overcome the torque of the coil spring 709 and rotate the rotating frame 707, so that the curved groove 708 can push the locking rod 705 connected to the short shaft 706 to slide outward of the stabilizing seat 702. After the pin 701 is fully inserted into the stabilizing seat 702, release the rotating frame 707. Under the torque of the coil spring 709, the curved groove 708 pushes the locking rod 705 to quickly return to its original position, so that one end of the locking rod 705 is inserted into the annular groove 703 and locks the pin 701, thus completing the connection between the device and the lampshade 3. When the light sensor 9 detects a strong light environment, start the motor 609. 609 drives gear 610 to rotate, causing rack 608 to rotate and annular pad 606 to rotate. This causes inclined block 607 to gradually push contact rod 605 along the inclined plane, allowing light-blocking plate 603 to overcome the torque of torsion spring 604 and rotate towards frosted light-transmitting plate 615, thus increasing the degree of light blocking by light-blocking plate 603 against light emitted by bulb 4. Motor 625 is then activated, driving gear 623, which meshes with gear 624, to rotate. This causes lead screw 619 to rotate and descend on annular platform 621, allowing lead screw 619 and round rod 620 to push slider 618 downwards on groove 617, causing the four light-blocking plates 8 to gradually retract inwards, thereby reducing the light transmittance of the device. When light sensor 9 detects dim ambient light, the above steps are reversed.
[0041] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
