Description

Technical Field

[0001] This invention relates to the field of lighting technology, and more specifically, to a lighting fixture with an adjustable light emission angle. Background Technology

[0002] High bay lights are common indoor lighting products. Different application scenarios require different beam angles. Typically, these strip high bay lights change the beam angle by changing the lens. This method is not only complex but can also lead to uneven lighting in extreme cases. Furthermore, the long, strip-shaped lens is relatively fragile and easily damaged during movement. Summary of the Invention

[0003] The purpose of this invention is to provide an adjustable light-emitting angle lighting device that can achieve different light emission angles, ensure the light emission angle and light uniformity of the product, ensure the strength of the lens structure, prevent lens damage, and avoid blocking the light emission.

[0004] To achieve the above objectives, the present invention provides an adjustable light-emitting angle lighting device, including a lamp body assembly and a lens assembly. The lamp body assembly includes a lampshade and a light source, with the light source disposed inside the lampshade and facing the lens. The lens assembly includes a lens, a driving member, and a reinforcing strip. The lens is located inside the lampshade, and the driving member drives the lens to move closer to or away from the light source. The lampshade, lens, and reinforcing strip are all elongated strips. The reinforcing strip is made of metal material and extends along the length direction of the lens. The reinforcing strip is disposed at the end of the lens in the width direction.

[0005] As can be seen from the above solution, by setting a push button on the lens, pushing the button moves the lens closer to or further away from the light source, thereby changing the distance between the lens and the LED, thus achieving the adjustment of different light emission angles. The structure is simple, enabling rapid adjustment of the emission angle while maintaining a horizontal light-emitting surface, ensuring uniform illumination and significantly improving the product's market competitiveness. Furthermore, by installing a reinforcing strip made of metal on the lens, lens deformation can be prevented, ensuring the product's light emission angle and uniformity. Simultaneously, since the reinforcing strip is usually opaque, placing it at both ends of the lens's width direction avoids obstructing the light emission.

[0006] A preferred embodiment is that the lens has a mounting groove extending along the length of the lens, and the reinforcing strip is located in the mounting groove and can be inserted into the mounting groove along the length of the lens.

[0007] It can be seen that the sliding fit between the reinforcing strip and the lens facilitates the installation of the reinforcing strip while preventing it from falling out of the mounting groove.

[0008] A further option is to provide a mounting groove on the side of the lens in the width direction, and to provide at least one reinforcing strip in the mounting groove.

[0009] A further embodiment involves an opening on the sidewall of the lens in the width direction, which communicates with a mounting groove. The height of the opening in the normal direction of the lens is less than the height of the mounting groove; and / or the width of the mounting groove in the width direction of the lens is less than its height in the normal direction of the lens; and / or the reinforcing strip is clearance-fitted with the mounting groove. Alternatively, mounting grooves may be provided on both sides of the lens in the width direction, and at least one reinforcing strip may be provided in each mounting groove.

[0010] Therefore, the height of the opening is less than the height of the mounting groove, which facilitates the limiting of the reinforcing strip in the width direction of the lens, preventing it from falling out of the mounting groove. The width of the mounting groove is less than its height, meaning the reinforcing strip is arranged vertically, further reducing light obstruction and ensuring the light-emitting effect. The gap fit between the reinforcing strip and the mounting groove ensures the stability of the reinforcing strip installation, preventing it from wobbling within the mounting groove, and also further guarantees the overall structural strength of the lens. The presence of reinforcing strips on both sides of the lens's width direction further enhances the overall strength of the lens assembly, preventing lens deformation.

[0011] A preferred embodiment is that the reinforcing strip includes a main body, a first bent portion, and a second bent portion. The main body is plate-shaped, and its normal is parallel to the width direction of the lens. The first bent portion and the second bent portion are respectively disposed at both ends of the main body in the width direction. In the thickness direction of the main body, the first bent portion and the second bent portion are located on the same side of the main body.

[0012] It is evident that by designing the reinforcing strip into a U-shaped structure, not only can the amount of material used be reduced and the cost lowered, but the obstruction of light output can also be reduced, while ensuring the overall strength of the lens.

[0013] In a preferred embodiment, the lamp body assembly further includes an inner support member disposed at the end of the lampshade along its length; the driving member includes a push button disposed at the end of the lens along its length, the push button being correspondingly disposed to the inner support member, at least a portion of the push button extending outside the lampshade, and the push button being forced to move the lens closer to or away from the light source.

[0014] Therefore, it can be seen that the inner support can limit the lens assembly in the length direction of the lens, preventing the lens assembly from moving in the length direction.

[0015] A further embodiment includes a spring-loaded latch at the end of the lens, extending parallel to the length of the lens and elastically deformable along the width of the lens. An inner support member has a second positioning hole extending through the lens along its length, and the spring-loaded latch passes through this hole and connects to a push button. The spring-loaded latch and the second positioning hole slide in a sliding engagement along the extension direction of the second positioning hole. Alternatively, there may be two or more inner support members and push buttons, with two inner support members positioned at opposite ends of the lampshade's length and two push buttons positioned at opposite ends of the lens's length, corresponding to the inner support members on the same side.

[0016] Therefore, the spring-loaded design can improve the stability of the connection between the mounting base, the inner support, and the push button, ensuring the smooth movement of the lens assembly.

[0017] A further option is to provide two or more positioning parts in the second positioning hole, with each positioning part arranged sequentially along the extension direction of the second positioning hole; adjacent positioning parts are connected by a transition part, the minimum width of the transition part is less than the minimum width of the positioning part; when the spring clip is located in the transition part, the transition part forces the spring clip to undergo elastic deformation, and when the spring clip is located in the positioning part, the spring clip returns to its natural state; or the deformation of the spring clip when it is located in the transition part is greater than the deformation of the spring clip when it is located in the positioning part.

[0018] As can be seen, by setting positioning parts and transition parts of different widths, when the spring clip moves to the transition part at the narrow position, the spring clip will undergo greater elastic deformation. When it moves to the positioning part at the wide position, the spring clip will restore its deformation or restore the deformation of the component. Therefore, during the adjustment process, the feel of the two positions is different, and the user can clearly feel that it has been adjusted to the right position, thereby improving the user experience.

[0019] A further embodiment is that the second positioning hole has a first sidewall and a second sidewall arranged opposite to each other. The first sidewall and the second sidewall each include two or more arc-shaped recesses. The number of arc-shaped recesses on the first sidewall is equal to the number of arc-shaped recesses on the second sidewall. The arc-shaped recesses on the first sidewall and the arc-shaped recesses on the second sidewall are arranged in a one-to-one correspondence. The two opposite arc-shaped recesses form a positioning part. An arc-shaped protrusion is formed between the two arc-shaped recesses on the same sidewall. The arc-shaped protrusion on the first sidewall and the arc-shaped protrusion on the second sidewall are arranged in a one-to-one correspondence. The two opposite arc-shaped protrusions form a transition part.

[0020] As can be seen, the alternation of the arc-shaped concave and arc-shaped convex parts achieves a smooth movement effect, further enhancing the user experience.

[0021] A preferred embodiment is that the spring clip includes a first cantilever and a second cantilever arranged along the width direction of the lens, with a deformation groove between the first and second cantilever, and both the first and second cantilever can elastically deform along the width direction of the lens.

[0022] It can be seen that by setting up a spring clip composed of two opposing cantilever arms, it is easy to realize the deformation and reset of the spring clip in the width direction of the lens.

[0023] In a preferred embodiment, the lens assembly further includes two mounting bases, which are respectively located at both ends of the lens along its length. The mounting bases have positioning grooves on the side facing the lens, and the ends of the lens and the reinforcing strip extend into the positioning grooves. Each mounting base has a spring clip located on the side of the corresponding mounting base facing away from the lens.

[0024] A further option is that the mounting base is also equipped with a buckle, and the reinforcing strip is equipped with a locking hole, with the buckle engaging and securing with the locking hole; and / or the mounting base is also equipped with a mounting protrusion on the side facing away from the lens, with the push button having a slot, and the mounting protrusion engaging with the slot.

[0025] As can be seen, after metal reinforcing strips are installed on both sides of the lens, the fixing base is fixed by engaging with the locking holes on the reinforcing strip through buckles. The fixing bases at both ends of the lens firmly fix the lens and the reinforcing strip to form a whole, so as to ensure that the left and right sides can be adjusted synchronously when the lens is adjusted, thereby ensuring the smoothness of adjustment.

[0026] A further embodiment is that the inner support has a first positioning hole extending through the lens along its length. The first positioning hole extends along the normal of the lens. After the mounting protrusion passes through the first positioning hole, it engages with the push button. The mounting protrusion and the first positioning hole slide in cooperation along the extension direction of the first positioning hole.

[0027] As can be seen, the first mounting protrusion is connected to the push button, ensuring the stability of the connection between the lens and the push button, and facilitating the movement of the lens by pushing the push button.

[0028] A further option is to have two or more spring clips, each spring clip being located on both sides of the mounting protrusion in the width direction of the lens; the number of second positioning holes is greater than or equal to the number of spring clips, with one spring clip slidingly engaging with one second positioning hole.

[0029] Therefore, multiple spring clips can further improve the user experience while ensuring smooth and stable movement.

[0030] A preferred embodiment is that the lighting fixture includes two or more lamp body assemblies and two or more lens assemblies, with each lamp body assembly and lens assembly arranged in a one-to-one correspondence, and each lamp body assembly arranged sequentially along the width direction of the lens.

[0031] Therefore, multiple lamp body components can increase the illumination range of lighting fixtures, and can also make two lamp body components form the same or different light emission angles as needed.

[0032] In a preferred embodiment, the lighting fixture further includes a mounting mechanism disposed at the top of the lighting fixture; the mounting mechanism includes at least one of a chain mounting structure, a rod mounting structure, and a ceiling mounting structure.

[0033] Therefore, it can be seen that the three installation methods—chain mounting structure, rod mounting structure, and ceiling mounting structure—can be selected for different locations, offering strong versatility, simple overall structure, and high reliability. Attached Figure Description

[0051] The present invention will be further described below with reference to the accompanying drawings and embodiments. Detailed Implementation

[0052] See Figures 1 to 5 In this embodiment, the adjustable-angle lighting fixture is a high-bay lamp. The high-bay lamp includes a power supply box 1, a mounting mechanism 2, two or more lamp body assemblies 3, and two or more lens assemblies 4. The lamp body assemblies 3 and lens assemblies 4 are arranged in a one-to-one correspondence, and each lamp body assembly 3 is arranged sequentially along the width direction of the lens 41. The power supply box 1 is elongated and is located between two of the lamp body assemblies 3. In this embodiment, the high-bay lamp includes two lamp body assemblies 3, two lens assemblies 4, and a power supply box 1. The power supply box 1 is located between the two lamp body assemblies 3 and is used to provide power to each light source 32. A sensor 11 is provided on the power supply box cover at the bottom of the power supply box 1. By setting the sensor 11, the high-bay lamp can be activated by sensing a human body, thus turning on when a person arrives and turning off when the person leaves.

[0053] See Figures 5 to 8 Each lamp body assembly 3 includes a lampshade 31, a light source 32, two inner support members 33 and two end caps 34. The light source 32 is disposed inside the lampshade 31 and faces the lens 41. In this embodiment, the light source 32 is a lamp plate, which is disposed on the top wall of the lampshade 31. In addition, the inner surface of the lampshade 31 is sprayed with high reflective powder.

[0054] See Figure 10 and Figure 11Each lens assembly 4 includes a lens 41, a driving member, two reinforcing strips 42, and two fixing seats 43. The lens 41 is located inside the lamp cover 31. The driving member includes two push buttons 44, which are respectively located at both ends of the lens 41 along its length. Each push button 44 corresponds to an inner support member 33. At least a portion of each push button 44 extends outside the lamp cover 31. When the push button 44 is subjected to force, it causes the lens 41 to move closer to or away from the light source 32. In this embodiment, the push part 443 of the push button 44 extends outside the lamp cover 31.

[0055] The lampshade 31, lens 41 and reinforcing strip 42 are all long strips, and two push buttons 44 are respectively located at both ends of the length of the lens 41.

[0056] The reinforcing strip 42 is made of metal and extends along the length of the lens 41. Mounting grooves 411 are provided at both ends of the lens 41 in the width direction. These grooves extend along the length of the lens 41 and penetrate it. One reinforcing strip 42 is located within one mounting groove 411, with a clearance fit. The reinforcing strip 42 can be inserted into the corresponding mounting groove 411 along the length of the lens 41. By installing the metal reinforcing strip 42 on the lens 41, deformation of the lens 41 can be prevented, ensuring the product's light emission angle and light uniformity. Furthermore, the sliding fit between the reinforcing strip 42 and the lens 41 facilitates installation, while the mounting grooves 411 limit the reinforcing strip 42 in the width direction of the lens 41, preventing it from falling out. Additionally, the presence of reinforcing strips 42 on both sides of the lens 41 in the width direction further enhances the overall strength of the lens assembly 4 and prevents lens 41 deformation.

[0057] An opening 412 is provided on the side wall of the lens 41 in the width direction. The opening 412 communicates with the mounting groove 411. In the normal direction of the lens 41, the height of the opening 412 is less than the height of the mounting groove 411. The width of the mounting groove 411 in the width direction of the lens 41 is less than the height of the mounting groove 411 in the normal direction of the lens 41. The height of the opening 412 being less than the height of the mounting groove 411 facilitates the limiting of the reinforcing strip 42 in the width direction of the lens 41, preventing the reinforcing strip 42 from falling out of the mounting groove 411. The width of the mounting groove 411 being less than its height ensures that the reinforcing strip 42 is arranged vertically within the mounting groove 411, further reducing light obstruction and guaranteeing the light emission effect.

[0058] The reinforcing strip 42 includes a main body 422, a first bent portion 423, and a second bent portion 424. The main body 422 is plate-shaped and vertically arranged within the mounting groove, meaning the normal of the main body 422 is parallel to the width direction of the lens 41. The first bent portion 423 and the second bent portion 424 are respectively located at both ends of the main body 422 in the width direction. In the thickness direction of the main body 422, the first bent portion 423 and the second bent portion 424 are located on the same side of the main body 422. By designing the reinforcing strip 42 as a U-shaped structure, not only can the material usage be reduced and the cost lowered, but the obstruction of light output can also be reduced, while ensuring the overall strength of the lens 41.

[0059] Two mounting bases 43 are respectively disposed at both ends of the lens 41 along its length. Each mounting base 43 has a positioning groove 431 on the side facing the lens 41, and the ends of the lens 41 and the reinforcing strip 42 extend into the corresponding positioning groove 431. Each mounting base 43 is also provided with a buckle 432, and the reinforcing strip 42 is provided with a locking hole 421 located on the main body 422 of the reinforcing strip 42. The buckle 432 and the locking hole 421 are fastened together along the width direction of the lens 41. Each mounting base 43 has a mounting protrusion 433 and a spring clip 434 on the side facing away from the lens 41. The extension direction of the mounting protrusion 433 and the spring clip 434 is parallel to the length direction of the lens 41, and the spring clip 434 can elastically deform along the width direction of the lens 41. After metal reinforcing strips 42 are installed on both sides of lens 41, the fixing seat 43 is engaged and fixed with the locking hole 421 on the reinforcing strip 42 by the buckle 432. The fixing seats 43 at both ends of lens 41 firmly fix lens 41 and reinforcing strip 42 to form a whole, so as to ensure that the left and right sides can be adjusted synchronously when lens 41 is adjusted, thereby ensuring smooth adjustment.

[0060] like Figures 6 to 9As shown, the two inner support members 33 of the lamp body assembly 3 are respectively disposed at both ends of the lamp cover 31 along the length direction. Each inner support member 33 is provided with a first positioning hole 331 and a second positioning hole 332 through the lens 41 along the length direction. The first positioning hole 331 extends along the normal of the lens 41, and the extension direction of the second positioning hole 332 is parallel to the first positioning hole 331. The push button 44 has a slot 441 and a limiting hole 442. The slot 441 is located inside the push part 443 of the push button 44 and extends from the push button 44 toward the side wall of the inner support member 33 and away from the inner support member 33. The mounting protrusion 433 passes through the first positioning hole 331 and engages with the slot 441 of the push button 44. The mounting protrusion 433 and the first positioning hole 331 slide in engagement along the extension direction of the first positioning hole 331. The spring buckle 434 passes through the second positioning hole 332 and extends into the limiting hole 442. The spring buckle 434 and the second positioning hole 332 slide in engagement along the extension direction of the second positioning hole 332. The inner support member 33 can limit the lens assembly 4 in the length direction of the lens 41 to prevent the lens assembly 4 from moving in the length direction.

[0061] Two or more positioning parts 3321 are provided inside the second positioning hole 332. The positioning parts 3321 are arranged sequentially along the extension direction of the second positioning hole 332. Adjacent positioning parts 3321 are connected by transition parts 3322. The minimum width of the transition parts 3322 is smaller than the minimum width of the positioning parts 3321. In this embodiment, there are three positioning parts 3321 and two transition parts 3322. The second positioning hole 332 has a first sidewall 333 and a second sidewall 334 arranged opposite to each other. The first sidewall 333 and the second sidewall 334 each include two or more arc-shaped recesses 335. The number of arc-shaped recesses 335 on the first sidewall 333 is equal to the number of arc-shaped recesses 335 on the second sidewall 334. In this embodiment, the number of arc-shaped recesses 335 on the first sidewall 333 and the number of arc-shaped recesses 335 on the second sidewall 334 are both three. The arc-shaped recesses 335 on the first sidewall 333 and the arc-shaped recesses 335 on the second sidewall 334 are arranged in a one-to-one correspondence. The two opposite arc-shaped recesses 335 form a positioning part 3321. An arc-shaped protrusion 336 is formed between two arc-shaped recesses 335 on the same sidewall. The arc-shaped protrusions 336 on the first sidewall 333 and the arc-shaped protrusions 336 on the second sidewall 334 are arranged in a one-to-one correspondence. The two opposing arc-shaped protrusions 336 form a transition portion 3322.

[0062] When the spring clip 434 is located at the transition section 3322, the transition section 3322 forces the spring clip 434 to undergo elastic deformation. When the spring clip 434 is located at the positioning section 3321, the spring clip 434 returns to its natural state. By setting the positioning section 3321 and the transition section 3322 with different widths, when the spring clip 434 moves to the narrow position of the transition section 3322, the spring clip 434 will undergo greater elastic deformation. When it moves to the wide position of the positioning section 3321, the spring clip 434 will restore its deformation or the deformation of the component. Therefore, during the adjustment process, the feel of the two positions is different, and the user can clearly feel that it has been adjusted to the correct position, thereby improving the user experience. The alternating arc-shaped concave portion 335 and arc-shaped convex portion 336 can achieve a smooth movement effect, further improving the user experience. In this embodiment, when the spring clip 434 is located at the positioning part 3321 closest to the light source 32, the distance between the lens 41 and the light source 32 is 2 mm, and the light emission angle of the high bay light is 90 degrees; when the spring clip 434 is located at the positioning part 3321 relatively close to the light source 32, the distance between the lens 41 and the light source 32 is 5.5 mm, and the light emission angle of the high bay light is 60 degrees; when the spring clip 434 is located at the positioning part 3321 furthest from the light source 32, the distance between the lens 41 and the light source 32 is 9.0 mm, and the light emission angle of the high bay light is 45 degrees.

[0063] The spring clip 434 includes a first cantilever 4341 and a second cantilever 4342 arranged along the width direction of the lens 41. A deformation groove 4343 is provided between the first cantilever 4341 and the second cantilever 4342. Both the first cantilever 4341 and the second cantilever 4342 can be elastically deformed along the width direction of the lens 41. By setting the spring clip 434 composed of two opposing cantilever arms, it is convenient to realize the deformation and reset of the spring clip 434 in the width direction of the lens 41.

[0064] There are two or more spring clips 434, each spring clip 434 being respectively disposed on both sides of the mounting protrusion 433 in the width direction of the lens 41. The number of second positioning holes 332 is greater than or equal to the number of spring clips 434. Each spring clip 434 is slidably engaged with one second positioning hole 332. In this embodiment, there are two second positioning holes 332 and two spring clips 434, with the two spring clips 434 respectively disposed on both sides of the mounting protrusion 433, and the two second positioning holes 332 respectively disposed on both sides of the two first positioning holes 331. The spring clips 434 on the fixing base 43 are slidably engaged with the second positioning holes 332 on the inner support member 33, which can limit the movement direction of the lens assembly 4.

[0065] like Figures 3 to 5 As shown, the two end caps 34 are respectively provided with the two ends of the lampshade 31 and are respectively covered by the inner support member 33 at the same end. The end cap 34 is provided with a clearance opening 341, and the push part 443 of the push button 44 extends from the clearance opening 341 to the outside of the end cap 34 for easy operation by the user.

[0066] See Figures 12 to 17 The mounting mechanism 2 is located at the top of the high bay light. The mounting mechanism 2 includes at least one of a chain mounting structure 21, a rod mounting structure 22, and a ceiling-mounted mounting structure 23. In this embodiment, the mounting mechanism 2 includes a chain mounting structure 21, a rod mounting structure 22, and a ceiling-mounted mounting structure 23. Figure 12 and Figure 13 As shown, the chain mounting structure 21 includes a chain mounting hole 211 provided on the end cap 34 and a chain 212 for fastening into the chain mounting hole 211. Figure 14 and Figure 15 As shown, the boom mounting structure 22 includes a mounting bracket 221 mounted on the power supply box 1 and a boom 222 mounted on the mounting bracket 221. The mounting bracket 221 has a boom mounting hole 2211 located on the top wall of the mounting bracket 221. Figure 16 and Figure 17 As shown, the ceiling-mounted structure 23 includes a mounting bracket 231 mounted on the power supply box 1 and screws 232 mounted on the mounting bracket 231. The mounting bracket 231 has ceiling-mounted holes 2311 and screws 232 for mating with the ceiling-mounted holes 2311. The three installation methods—chain mounting structure 21, rod mounting structure 22, and ceiling-mounted structure 23—allow for selection of one method for different applications, offering strong versatility, a simple overall structure, and high reliability. Optionally, in other embodiments, the rod mounting structure 22 and the ceiling-mounted structure 23 can use the same mounting bracket, which has rod mounting holes and ceiling-mounted holes. The rod mounting holes are located in the middle of the top wall of the mounting bracket, and the ceiling-mounted holes are located on both sides of the rod mounting holes.

[0067] As can be seen from the above, by setting a push button on the lens, the lens can be moved closer to or away from the light source by pushing the push button, thereby changing the distance between the lens and the lamp bead to achieve the adjustment of different light emission angles. The structure is simple and can achieve the purpose of quickly adjusting the light emission angle. At the same time, the light emission surface can be kept horizontal while changing the light emission angle, ensuring the uniformity of product lighting and greatly improving the product's market competitiveness.

[0068] Furthermore, each mounting slot can also contain two or more reinforcing strips, which can be arranged along the length of the lens, or along the depth or width of the mounting slot. When the spring clip is located at the positioning part, it can also be in a slightly deformed state, and the deformation of the spring clip when it is located at the transition part is greater than the deformation of the spring clip when it is located at the positioning part. The number and size of the inner support, reinforcing strips, spring clip, first positioning hole, and second positioning hole can all be changed as needed. The shape of the lampshade, lens, and light source can also be changed as needed. The driving component can also include a motor and a driving rod, with the driving rod connected to the lens. The motor drives the driving rod to move up and down, realizing the movement of the lens relative to the light source. Each lens assembly can also include only one push button or two or more push buttons, which are located at the end of the lens along its length. The above modifications can also achieve the purpose of the present invention.
