Description

Technical Field

[0001] The utility model relates to the technical field of optical lenses, in particular to an optical lens assembly for an LED light box. Background Art

[0002] Large-size LED light boxes use more backlight sources, and the existing backlight sources are all low-power LEDs plus LED secondary optical lenses. The LED light strips are connected by wires or steel wires, and the spacing between the light strips is small. The brightness requirements are met by the number of LEDs.

[0003] The lens assembly needs to be baked to solidify the glue. However, since the spacer that plays a light-shielding role in the optical lens is easy to deform during the baking process, when the deformation of the spacer is too large, glare is easy to form at the deformed position. When the overall area of ​​the optical lens is large, when the lens is partially damaged, the entire lens needs to be replaced, which increases the cost of using the lens. Summary of the invention

[0004] The purpose of the utility model is to provide an optical lens assembly for an LED light box to solve the above-mentioned defects caused by the prior art.

[0005] An optical lens assembly for an LED light box comprises a frame body and an optical lens. A fin plate is arranged inside the frame body. A limiting mechanism is arranged inside the frame body. The limiting mechanism positions the outer side of the optical lens and separates and assembles multiple groups of optical lenses of the same size. A positioning mechanism is arranged directly above the frame body. The positioning mechanism positions the installed optical lens to prevent the optical lens from loosening after installation.

[0006] Preferably, the limiting mechanism includes a separator, an optical lens, a lens support, an air hole and a positioning hole. The separator is evenly spaced inside the frame body, lens supports are symmetrically provided on the outside of the separator, positioning holes are penetrated on the outside of the lens support, the top of the lens support is connected to the optical lens, and air holes are penetrated on both sides of the frame body.

[0007] Preferably, the lens support is connected to the bottom end of the optical lens by a positioning hole extending therethrough.

[0008] Preferably, the positioning mechanism includes side guide grooves, a sealing cover plate, fasteners and hard rubber strips, the side guide grooves are symmetrically opened on both sides of the separator, multiple groups of the separators are symmetrically welded to the inner end of the frame body, the sealing cover plate is arranged at the top end of the frame body, the outer side of the sealing cover plate is rectangularly distributed with fasteners, and the bottom end of the sealing cover plate is evenly spaced with hard rubber strips.

[0009] Preferably, the separator is connected to both sides of the lens support through symmetrically arranged side guide grooves.

[0010] Preferably, the sealing cover plate is connected to the side guide groove via hard rubber strips connected at equal intervals at the bottom end.

[0011] Compared with the prior art, the utility model has the following advantages:

[0012] 1. During use, multiple groups of optical lenses with the same size are positioned by means of equally spaced separators. When one group of optical lenses is damaged, the individual optical lenses can be positioned and disassembled, thereby reducing the cost of repairing damaged optical lenses during use. By inserting a hard rubber strip into the side guide groove, the two sides of the lens support are squeezed and limited to prevent the lens support from shaking.

[0013] 2. The optical lens and the lens support are glued together to avoid the glare caused by the deformation of the separator during baking, which affects the imaging quality of the lens. At the same time, a single optical lens and lens support assembly is used for rapid assembly, thereby ensuring the optical performance of the lens. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] like Figures 1 to 4As shown, an optical lens assembly for an LED light box includes a frame body 1 and an optical lens 5. A fin plate 12 is arranged inside the frame body 1. A limiting mechanism 6 is arranged inside the frame body 1. The limiting mechanism 6 positions the outer side of the optical lens and separates and assembles multiple groups of optical lenses of the same size. A positioning mechanism 8 is arranged directly above the frame body 1. The positioning mechanism 8 positions the installed optical lens 5, thereby preventing the optical lens 5 from loosening after installation.

[0022] In this embodiment, the limiting mechanism 6 includes a separator 2, an optical lens 5, a lens support 7, an air vent 10 and a positioning hole 13. The separator 2 is evenly spaced inside the frame body 1. The lens support 7 is symmetrically provided on the outer side of the separator 2. The positioning hole 13 is penetrated through the outer side of the lens support 7. The top of the lens support 7 is connected to the optical lens 5. Air vents 10 are penetrated on both sides of the frame body 1.

[0023] In this embodiment, the lens support plate 7 is connected to the bottom end of the optical lens 5 by a positioning hole 13 formed therethrough. After the bottom end of the optical lens 5 is bonded through the positioning hole 13, the LED light is directly emitted through the optical lens 5.

[0024] In this embodiment, the positioning mechanism 8 includes a side guide groove 3, a sealing cover plate 4, a fastener 9 and a hard rubber strip 11. The side guide groove 3 is symmetrically opened on both sides of the separator 2. Multiple groups of the separators 2 are symmetrically welded to the inner end of the frame body 1. The sealing cover plate 4 is arranged at the top of the frame body 1. The outer side of the sealing cover plate 4 is rectangularly distributed with fasteners 9. The bottom end of the sealing cover plate 4 is evenly spaced with hard rubber strips 11. The sealing cover plate 4 and the frame body 1 are assembled and positioned by the fasteners 9.

[0025] In this embodiment, the separator 2 is connected to both sides of the lens support 7 through symmetrically provided side guide grooves 3. The side guide grooves 3 are used to position both sides of the lens support 7 to prevent the lens support 7 from loosening.

[0026] In this embodiment, the sealing cover plate 4 is connected to the side guide groove 3 via hard rubber strips 11 connected at equal intervals at the bottom end. The hard rubber strips 11 are used to squeeze and position the two sides of the lens support plate 7 connected inside the side guide groove 3 to prevent the lens support plate 7 from loosening.

[0027] The actual application of this optical lens assembly for LED light boxes includes the following work contents:

[0028] Step 1: The operator first aligns the lens support 7 with the optical lens 5, and aligns the positioning hole 13 provided through the lens support 7 with the center point of the optical lens 5, and glues the optical lens 5 and the lens support 7 together, and solidifies the glue of the optical lens 5 and the lens support 7 with an ultraviolet lamp, and then inserts the lens support 7 into the side guide grooves 3 provided on both sides, and positions the lens support 7 and the optical lens 5 through the symmetrically provided separators 2;

[0029] Step 2: The operator inserts the hard rubber strips 11 at the bottom end of the sealing cover plate 4 with equal intervals, so that the hard rubber strips 11 at the bottom end of the sealing cover plate 4 are inserted into the corresponding side guide grooves 3, and the hard rubber strips 11 are inserted into both sides of the lens support 7 for compression to prevent the lens support 7 and the optical lens 5 from loosening. The operator can also bond the glass to one side of the frame body 1 to protect the optical lens 5;

[0030] Step 3: Then, the sealing cover plate 4 is attached to the top of the frame body 1, and the fastener 9 is inserted into the inside of the sealing cover plate 4, so that the fastener 9 locks the sealing cover plate 4 and the frame body 1. At the same time, the operator can install the LED light panel at the bottom of the sealing cover plate 4, and the light is emitted by the LED light panel, and is directly irradiated through the optical lenses 5 arranged at equal intervals;

[0031] Step 4: The air from the outside is introduced into the interior of the frame body 1 through the air vent 10 opened on one side, and the air is transported through the hollow cavity set inside the frame body 1 to accelerate the removal of the heat generated by the operation inside the frame body 1, and the heat of the LED lamp panel is absorbed through the fin plate 12, so as to facilitate the transfer and cooling of the heat inside the frame body 1.

[0032] Therefore, the embodiments disclosed above are only illustrative in all aspects and are not exclusive. All changes within the scope of the present invention or within the scope equivalent to the present invention are included in the present invention.
