Description

Technical Field

[0001] This invention relates to the field of LED lighting technology, and more particularly to an LED lighting fixture with an anti-glare light-shielding grille. Background Technology

[0002] LED lights are a new type of lighting equipment that uses light-emitting diodes as the light source. They have advantages such as low energy consumption, long lifespan, fast response speed, and environmental friendliness. They are widely used in various fields such as indoor and outdoor building lighting, industrial production lighting, and road lighting.

[0003] To prevent glare from direct LED light sources and thus avoid eye strain, LED lights are typically equipped with light-shielding grilles. These grilles generally consist of a frame, an installation structure, and multiple parallel light-shielding blades. The blades limit the angle of light, preventing direct light from entering the eyes and causing strong light stimulation, thus reducing glare intensity.

[0004] However, for double-sided folding LED lights, which include two LED light-emitting surfaces that can rotate relative to each other, although the fixed installation of grilles on the light-emitting surfaces can achieve the anti-glare effect, the angle of the grilles will also change when the angle of the LED light-emitting surfaces is adjusted. This causes the gap between the grilles to no longer face the front of the lamp body. In this case, the grilles will significantly block the light, affecting the brightness and lighting effect of the LED light. Summary of the Invention

[0005] The purpose of this invention is to solve the problem that, although the existing double-sided folding LED lights can achieve an anti-glare effect after the grille is installed, the grille will block the light after the angle is adjusted. Therefore, this invention proposes an LED light fixture with an anti-glare and light-shielding grille.

[0006] To achieve the above objectives, the present invention employs the following technology: an LED lamp with an anti-glare and light-shielding grille, comprising a frame, wherein two rotating shafts are rotatably connected to one side of the frame, and a mounting frame is rotatably connected to the rotating shafts via connectors; a plurality of LED light strips are equidistantly and parallelly installed inside the mounting frame; and further comprising:

[0007] The grid unit, the deflection mechanism, and the adjustment structure that can limit the rotation of the shaft are arranged in pairs in parallel inside the mounting frame. The grid unit includes a blade, and both ends of the blade are fixed with a rotating seat that is rotatably connected to the mounting frame. One end of the rotating seat is fixed with a gear.

[0008] When adjusting the angle of the mounting frame, the deflection mechanism drives each blade to deflect synchronously through gear one and rotating seat. The blades deflect in opposite directions and at the same speed as the mounting frame, so that the gap between the blades always faces the front of the lamp body.

[0009] As a further description of the LED lamp with anti-glare and light-shielding grille of the above-mentioned technology: the deflection mechanism includes a second gear fixed on a rotating shaft, the second gears on the two rotating shafts meshing with each other, a third gear meshing with the second gear is rotatably connected inside the mounting frame, a rack meshing with the third gear is slidably connected inside the mounting frame, and the rack is connected to a gear frame that meshes with the first gear through a T-shaped rod.

[0010] As a further description of the LED lamp with anti-glare and light-shielding grille mentioned above: the gear three is composed of an upper gear and a lower gear fixed together, the upper gear is the same model as gear one, and the lower gear is the same model as gear two.

[0011] As a further description of the LED lamp with anti-glare and light-shielding grille mentioned above: the connector is rotatably connected to the rotating shaft and has convex teeth on its surface, and engages with the two connectors fixed to the mounting frame through the convex teeth.

[0012] As a further description of the LED lamp with anti-glare and light-shielding grille mentioned above: the adjustment structure includes a sleeve fixed to the top of the frame, a rotating head rotatably connected inside the sleeve and slidably connected to the top of the rotating shaft, a friction sleeve fixed outside the rotating head, and a spring provided at the bottom of the friction sleeve.

[0013] As a further description of the LED luminaire with anti-glare shading grille mentioned above: the grille unit also includes reflectors and matte sheets respectively fixed to both sides of the blade.

[0014] As a further description of the LED lamp with anti-glare and light-shielding grille mentioned above: a toothed frame is provided inside the mounting frame, and a switching mechanism is installed at the bottom of the toothed frame.

[0015] As a further description of the LED lamp with anti-glare and light-shielding grille mentioned above: both sides of the inner wall of the second toothed frame are provided with tooth grooves, and one end of the second toothed frame is provided with a T-shaped groove that cooperates with the T-shaped rod.

[0016] As a further description of the LED lamp with anti-glare and light-shielding grille mentioned above: the switching mechanism includes a strip frame slidably connected inside the mounting frame, both toothed frame one and toothed frame two are slidably connected inside the strip frame, a pair of sliders are slidably connected inside the mounting frame, a threaded rod is hinged between the sliders and the strip frame, and a threaded rod that is threadedly connected to the two sliders is rotatably connected inside the mounting frame.

[0017] As a further description of the LED luminaire with anti-glare and light-shielding grille mentioned above: the mounting frame is fixed with an elastic buckle on the side near the frame.

[0018] In summary, due to the adoption of the above-mentioned technology, the beneficial effects of this invention in providing an LED lamp with an anti-glare and light-shielding grille are as follows:

[0019] 1. In this application, when adjusting the angle of the mounting frame to make the light emitted by the LED light strip more focused and improve the lighting effect, the mounting frame rotates around the pivot through the connector, driving gear three to make a circular motion around gear two. While gear three is making a circular motion, it also rotates, driving the rack to push the gear frame one through the T-shaped rod. Then, through gear one and the rotating seat, it drives each blade to deflect synchronously in the same direction. The blades rotate in opposite directions to the mounting frame and the angle is always consistent. The gap between the blades always faces the front of the lamp body. Compared with the existing device, this application can not only reduce the glare of the double-sided folding LED lamp in a wide range of lighting modes and avoid irritating the eyes, but also automatically deflect the grid unit through the deflection mechanism when the lamp is folded to achieve a focusing effect. This prevents glare while avoiding significant light obstruction and ensuring the lighting effect of the lamp.

[0020] 2. Press down and rotate the rotating head to drive the rotating shaft to rotate. Through the deflection mechanism, the gear 1, rotating seat and blades are driven to deflect, which can realize the manual adjustment of the blade angle and control the gap width between the blades, thereby controlling the degree of light blocking by the blades and adjusting the anti-glare effect to adapt to different usage scenarios and improve the applicability of the device.

[0021] 3. Reflectors and matte sheets are provided on both sides of the blade. When the matte sheets face the LED light strip, they can block the light to achieve an anti-glare effect. When the reflectors face the LED light strip, the switching mechanism drives the gear frame 2 and gear frame 1 to rise, so that gear frame 2 replaces gear frame 1 and meshes with gear 1. Then, through the adjustment structure and deflection mechanism, the grid units on both sides in front of the LED light strip are deflected and opened in the opposite direction. This design can ensure the light intensity and further expand the light illumination range when the lamp provides large-area illumination, thereby improving the effect of large-area illumination.

[0045] The following will describe, with reference to the accompanying drawings of the embodiments of the present invention, a clear and complete description of an LED lamp with an anti-glare light-shielding grille. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0046] like Figures 1-16 As shown, the present invention provides an LED lamp with an anti-glare light-shielding grille: including a frame 10, two rotating shafts 11 are rotatably connected to one side of the frame 10, and a connector 14 is rotatably connected to the rotating shaft 11. A mounting frame 12 is fixed to one side of the connector 14. The two mounting frames 12 are rotatably connected to the two rotating shafts 11 respectively through the connector 14. The surface of the connector 14 is provided with protruding teeth, and the connectors 14 fixed to the two mounting frames 12 are engaged by the protruding teeth. The two mounting frames 12 are symmetrically arranged and a plurality of LED light strips 13 are installed in parallel at equal intervals inside.

[0047] The two mounting frames 12 are arranged at a 180-degree angle, with their backs fitting against the frame 10. The two mounting frames 12 can be deflected relative to each other, making the light emitted from the LED strip 13 more focused and improving the lighting effect. Considering the lighting effect of the LED strip 13, the optimal deflection angle of the mounting frames 12 is 30 degrees or less. Figure 14 As shown, the two mounting frames 12 are deflected relative to each other by 30 degrees.

[0048] Under the transmission action of the connector 14, manually adjusting the angle of one of the mounting frames 12 can drive the other mounting frame 12 to deflect synchronously in the opposite direction, so that the two mounting frames 12 can open and close synchronously, so as to facilitate the angle adjustment of the LED light strip 13.

[0049] The mounting frame 12 is fixed with an elastic buckle 15 on the side near the frame 10. When the two mounting frames 12 are fully open, that is, when they are at an angle of 180 degrees, the elastic buckle 15 on the back of the mounting frame 12 engages with the slot on the frame 10, so that the mounting frame 12 remains stable.

[0050] Reference Figure 6 and Figure 7Each mounting frame 12 has several pairs of parallel grid units 20 inside. Each grid unit 20 includes a blade 21. Both ends of the blade 21 are fixed with a rotating seat 24 that is rotatably connected to the mounting frame 12. One end of the rotating seat 24 is fixed with a gear 25. Each pair of two blades 21 are located on both sides in front of the LED light strip 13 to block the light, so that the light emitted by the LED light strip 13 can only be emitted forward, avoiding the light from directly entering the eyes and achieving the anti-glare effect.

[0051] Reference Figure 4 , Figure 5 and Figure 10 To prevent the blade 21 from moving along with the mounting frame 12 and blocking the LED light strip 13 from the front of the lamp body after the mounting frame 12 is adjusted, thus reducing the lighting effect of the LED light strip 13, a deflection mechanism 30 is provided inside the mounting frame 12. The deflection mechanism 30 includes a second gear 31 fixed on the rotating shaft 11. The two gears 31 on the rotating shaft 11 mesh with each other. A third gear 32 that meshes with the second gear 31 is rotatably connected inside the mounting frame 12. A rack 33 that meshes with the third gear 32 is slidably connected inside the mounting frame 12. A T-shaped rod 34 is fixed to one end of the rack 33 that extends into the mounting frame 12. A gear frame 35 that meshes with the first gear 25 is slidably connected to the end of the T-shaped rod 34.

[0052] like Figure 11 The specific shape of the gear frame 35 is shown. One side of the inner wall of the gear frame 35 is provided with a tooth groove, which meshes with all the gears 25 through the tooth groove. Therefore, when the gears 25 move laterally, they can drive all the gears 25 to deflect synchronously in the same direction.

[0053] When the mounting frame 12 rotates around the rotating shaft 11 via the connector 14, the mounting frame 12 drives the gear 32 to make a circular motion around the gear 21. Since the gear 32 meshes with the gear 21, the gear 32 rotates while making a circular motion, which drives the rack 33 to slide towards the inside of the mounting frame 12. The rack 33 pushes the gear frame 35 through the T-shaped rod 34, thereby driving each gear 25 to rotate synchronously in the same direction. Through the rotating seat 24, each blade 21 is deflected synchronously in the same direction, and the rotation direction of the blade 21 is opposite to the deflection direction of the mounting frame 12.

[0054] Among them, gear 32 is composed of an upper gear and a lower gear. The upper gear is the same model as gear 25, and the lower gear is the same model as gear 21. When the mounting frame 12 rotates around the rotating shaft 11, the deflection angle of the mounting frame 12 is always the same as the rotation angle of gear 32. The deflection angle of the upper gear is the same as that of gear 25. Therefore, the deflection angle of the mounting frame 12 is always the same as the rotation angle of the blade 21. The rotation directions of the mounting frame 12 and the blade 21 are opposite, so that the gap between the blades 21 always faces the front of the lamp body and will not block the light of the LED light strip 13. Figure 14 The state shown.

[0055] Compared to existing devices, the above design not only reduces glare from LED light strips 13 by using the grille unit 20 to block light, but also works in conjunction with the angle adjustment of the two mounting frames 12. When the two mounting frames 12 deflect relative to each other to concentrate the light from the LED light strips 13 and improve the lighting effect, the blade 21 deflects in coordination to avoid blocking the light, thereby effectively improving the performance of the device.

[0056] Reference Figure 3 and Figure 13 To further improve the performance of the grid unit 20, an adjustment structure 60 is provided at the top of the frame 10. The adjustment structure 60 includes a sleeve 61 fixed to the top of the frame 10. A rotating head 62 is rotatably connected inside the sleeve 61 and slidably connected to the top of the rotating shaft 11. A friction sleeve 64 is fixed outside the rotating head 62. The friction sleeve 64 is located inside the sleeve 61. A spring 63 is provided at the bottom of the friction sleeve 64. The spring 63 is always in a compressed state. Under the elastic force of the spring 63, the top surface of the friction sleeve 64 contacts the inner wall of the sleeve 61 and there is friction on the contact surface. The friction restricts the relative rotation of the friction sleeve 64 and the sleeve 61, thereby restricting the rotation of the rotating head 62 and the rotating shaft 11. Since the gears 31 on the two rotating shafts 11 mesh with each other, the rotating shaft 11 that is slidably connected to the rotating head 62 and restricted from rotation will restrict the rotation of the other rotating shaft 11 through the gear frame 41, so as to prevent the rotating shaft 11 from rotating on its own when the mounting frame 12 rotates around the rotating shaft 11 through the connector 14.

[0057] Manually pressing down the rotating head 62 further compresses the spring 63. The rotating head 62 drives the friction sleeve 64 to move downward, causing the top surface of the friction sleeve 64 to disengage from the inner wall of the sleeve 61. Then, manually rotating the rotating head 62 drives the connected rotating shaft 11 to rotate, causing the rotating shaft 11 to drive the gear 2 31 to rotate. This, in turn, through the gear 3 32, rack 33, T-shaped rod 34, and gear frame 35, drives the gear 25, rotating seat 24, and blade 21 to deflect, thus achieving manual adjustment of the blade 21 angle. Figure 15As shown, the gap width between adjacent blades 21 can be controlled by manually adjusting the angle of the blade 21, thereby controlling the degree to which the blade 21 blocks light and adjusting the anti-glare effect to adapt to different usage scenarios.

[0058] Reference Figure 7 Although the grille unit 20 can reduce glare, it reduces the lighting range and light intensity, making it difficult to meet the needs of large-area lighting. To compensate for this deficiency, reflectors 22 and matte sheets 23 are fixed on both sides of the blade 21.

[0059] When the matte sheet 23 on each pair of blades 21 faces the LED light strip 13, it can reduce glare by blocking the light and limiting the angle of light illumination. When a large area of ​​light is needed, the reflective sheet 22 on each pair of blades 21 can face the LED light strip 13, and the light from the LED light strip 13 can be reflected by the reflective sheet 22 to ensure light intensity and expand the illumination range.

[0060] Based on the above design, the positions of reflector 22 and matte sheet 23 can be switched by rotating blade 21 by 180 degrees. Since the position of the rotating seat 24 and the middle section of the blade 21 is fixed, the distance between adjacent blades 21 needs to be greater than the width of blade 21 in order to meet the switching conditions.

[0061] Reference Figure 10 and Figure 12 To maximize the illumination range using the reflector 22, a gear frame 21 is provided inside the mounting frame 12. Both sides of the inner wall of the gear frame 21 have toothed grooves. Several gears 1 25 interlock and mesh with the toothed grooves on both sides of the inner wall of the gear frame 21. When the gear frame 21 moves axially, each pair of gears 1 25 moves synchronously in the opposite direction, allowing the leaf plates 21 located on both sides of the LED light strip 13 to drive the reflector 22 to open. Figure 16 As shown, the light emitted by the LED light strip 13 is reflected to expand the lighting range. One end of the toothed frame 41 is provided with a T-shaped groove that cooperates with the T-shaped rod 34.

[0062] Reference Figures 8-10 The bottom of the gear frame 41 is equipped with a switching mechanism 50 for meshing the gear frame 41 with the gear 25. The switching mechanism 50 includes a strip frame 51 that is vertically slidably connected inside the mounting frame 12. The gear frame 35 and the gear frame 41 are both slidably connected inside the strip frame 51. A pair of sliders 52 are slidably connected laterally inside the mounting frame 12. A support plate 54 is hinged between the two sliders 52 and the strip frame 51. The two support plates 54 are symmetrically arranged. A threaded rod 53 is rotatably connected inside the mounting frame 12. The threads at both ends of the threaded rod 53 are opposite in direction. The two sliders 52 are respectively connected to the opposite threads at both ends of the threaded rod 53.

[0063] Manually turning the head 62 causes the blade 21 to rotate 180 degrees via the shaft 11 and deflection mechanism 30, switching the positions of the reflector 22 and matte sheet 23. The T-shaped rod 34 is then positioned above the T-shaped groove of the gear frame 41. Then, rotating the threaded rod 53 causes the two sliders 52 to slide towards each other, supporting the frame 51 upwards via the support plate 54. The upward movement of the frame 51 causes the gear frame 35 and gear frame 41 to move upwards. The gear frame 35 disengages from the gear 25, while the gear frame 41 engages with the gear 25, and the T-shaped groove engages with the T-shaped rod 34. Afterward, manually turning the head 62 causes the gear frame 41 to move axially via the shaft 11, gear 31, gear 32, rack 33, and T-shaped rod 34, allowing the blades 21 on both sides of the LED light strip 13 to open the reflector 22, reflecting light and expanding the illumination range.

[0064] Working principle: In the initial state, the spring 63 is in a compressed state. The elastic force of the spring 63 causes the top surface of the friction sleeve 64 to abut against the inner wall of the sleeve 61. The friction between the sleeve 61 and the friction sleeve 64 restricts the rotation of the rotating head 62 and the rotating shaft 11. The rotating shaft 11 restricts the rotation of another rotating shaft 11 through the gear 31. The matte blades 23 on each pair of blades 21 face between the two blades 21.

[0065] When the angle of the mounting frame 12 is manually adjusted so that one of the mounting frames 12 deflects around the pivot 11, the mounting frame 12 drives the other mounting frame 12 to deflect synchronously in the opposite direction through the connector 14 and the protruding teeth on the connector 14, thereby achieving relative deflection of the two mounting frames 12, which makes the light emitted by the LED light strip 13 installed inside the mounting frame 12 more focused.

[0066] When the mounting frame 12 rotates around the rotating shaft 11 via the connector 14, it drives the gear 32 to make a circular motion around the gear 21. Since the gear 32 meshes with the gear 21, the gear 32 rotates on its own while making a circular motion, which drives the rack 33 to slide towards the inside of the mounting frame 12. The rack 33 pushes the gear frame 35 through the T-shaped rod 34, thereby driving each gear 25 to rotate synchronously in the same direction. Through the rotating seat 24, each blade 21 is deflected synchronously in the same direction. The blade 21 and the mounting frame 12 deflect in opposite directions and at the same speed, so that the gap between the blades 21 always faces the front of the lamp body and does not block the light of the LED light strip 13.

[0067] Manually rotate one of the mounting frames 12 in the opposite direction to unfold it. Similar to the transmission principle described above, both mounting frames 12 return to a 180-degree position and are engaged with the frame 10 via elastic buckles 15 to ensure stability.

[0068] When the anti-glare effect needs to be adjusted, manually press down the rotating head 62 to further compress the spring 63. The rotating head 62 drives the friction sleeve 64 to move down, causing the top surface of the friction sleeve 64 to disengage from the inner wall of the sleeve 61. Then, manually rotating the rotating head 62 can drive the connected rotating shaft 11 to rotate, causing the rotating shaft 11 to drive the gear 2 31 to rotate. This, in turn, drives the gear 1 25, rotating seat 24 and blade 21 to deflect through the gear 3 32, rack 33, T-shaped rod 34 and gear frame 1 35, thus realizing the manual adjustment of the angle of the blade 21. By manually adjusting the angle of the blade 21, the gap width between adjacent blades 21 can be controlled, thereby controlling the degree to which the blade 21 blocks light and adjusting the anti-glare effect.

[0069] When it is necessary to enhance the illumination range, the blade 21 is rotated 180 degrees by adjusting the structure 60, which switches the positions of the reflector 22 and matte sheet 23 on the blade 21. At this time, the T-shaped rod 34 is located above the T-shaped groove of the gear frame 41. Then, the threaded rod 53 is rotated to drive the two sliders 52 to slide relative to each other. The support plate 54 lifts the frame 51 upward. The upward movement of the frame 51 causes the gear frame 35 and the gear frame 41 to move upward, and the gear frame 35 disengages from the gear 25. The gear frame 41 meshes with the gear 25 and the T-slot engages with the T-bar 34. Then, by manually turning the rotating head 62, the gear frame 41 can be moved axially through the rotating shaft 11, gear 31, gear 32, rack 33 and T-bar 34. This allows the blades 21 on both sides of the LED light strip 13 to open the reflector 22 to reflect light and expand the lighting range. The opening angle of the reflector 22 can also be adjusted by turning the rotating head 62 to control the adjustment range.
