Description

Technical Field

[0001] This utility model belongs to the technical field of laser engraving display lights, specifically relating to an LED laser engraving display light that prevents panel collapse. Background Technology

[0002] LED laser engraving display lights are lighting devices used to display the three-dimensional images inside laser-engraved crafts (such as transparent media like crystal, glass, and acrylic). Through built-in LED light sources, light guide structures, and control circuits, they illuminate the engraved area evenly from the bottom or side, enhancing the three-dimensionality, transparency, and visual impact of the engraved pattern. They are commonly used in art exhibitions, souvenir displays, and commercial displays.

[0003] Our company has designed a box-type LED laser-engraved display light with a light guide plate in the center of the panel, which is glued to a notch in the panel. To improve aesthetics, the design requires the top surfaces of the panel and the light guide plate to be flush. Since the light guide plate is transparent while the display light body and panel are black, if the light guide plate is fitted into the panel from top to bottom, the glue marks between the light guide plate and the supporting parts will be visible, reducing the product's aesthetics, especially noticeable when the light guide plate is translucent. If the light guide plate is designed to be embedded into the notch in the panel from bottom to top, the glue line will be located at the bottom of the panel, achieving the aesthetic requirement. However, when laser-engraved crystal crafts are placed on the light guide plate and panel, because the light guide plate is embedded from bottom to top, the direction of gravity is consistent with the peeling direction of the adhesive interface, causing the adhesive layer to be subjected to combined shear and peel stress, making the adhesive interface prone to fatigue and delamination. This results in the light guide plate easily detaching from the panel after the laser-engraved crystal crafts are placed on it.

[0004] Meanwhile, the panel is made of plastic and is relatively thin. The insertion of the light guide plate weakens the overall strength. Long-term pressure may cause local deformation or collapse, thus affecting the overall structural stability and service life of the display light. Utility Model Content

[0005] To address the aforementioned shortcomings of existing technologies, this invention aims to solve the problem that in conventional LED laser engraving display lights, the light guide plate is embedded from bottom to top into the panel's notch. While this satisfies the aesthetic requirement of concealing adhesive residue, the light guide plate is prone to detachment under the weight of laser-engraved crystal crafts. Furthermore, the thin panel with the notch is prone to collapse after prolonged use. The purpose of this invention is to provide an LED laser engraving display light that prevents panel collapse. A support block is provided below the panel's insertion opening, and the light guide plate is fitted into the opening from top to bottom. At the contact point between the light guide plate and the support block, a coating identical to that on the panel is screen-printed onto the light guide plate, concealing adhesive residue. Simultaneously, crisscrossing reinforcing ribs are provided at the bottom of the panel, and multiple evenly spaced support rods are installed within the housing to support the panel. This significantly reduces the risk of the light guide plate detaching and the panel collapsing, while maintaining a residue-free appearance.

[0006] To achieve the above objectives, the utility model adopts the following technical solution: an LED laser engraving display light for preventing panel collapse, comprising:

[0007] The lamp body has an internal cavity containing a light-emitting panel. Multiple evenly arranged support rods are mounted on the bottom plate of the lamp body cavity, with the upper surface of the support rods fitting against the lower surface of the panel.

[0008] The panel has clips for insertion into the lamp body. A support block is located below the panel's insertion opening, with the support block having the same shape as the edge of the insertion opening. The support block includes a support portion for supporting the light guide plate and a connecting portion for connecting to the bottom surface of the panel. The lower surface of the panel also has crisscrossing reinforcing ribs, at least some of which are connected to the support block.

[0009] The light guide plate is installed inside the panel recess and is supported at the bottom by the panel support block in contact with it. The part of the light guide plate in contact with the support block is coated with a coating of the same color as the panel.

[0010] According to another embodiment of the utility model or any of the foregoing embodiments, the support block has a width of not less than 4mm and a thickness of not less than 1.2mm. As a reinforcing structure, the support block, through repeated experiments, has parameters suitable for the weight of the laser-engraved crystal, resulting in the best support effect.

[0011] According to another embodiment of the utility model or any of the foregoing embodiments, the display lamp is wherein the support block, the reinforcing rib and the panel are integrally injection molded, and the support rod and the lamp body are integrally injection molded.

[0012] According to another embodiment of the utility model or any of the foregoing embodiments, the display lamp has at least three support rods, which are hollow structures.

[0013] According to another embodiment of the utility model or any of the foregoing embodiments, the display lamp body has at least four evenly arranged anti-slip pads on its bottom to prevent the lamp body from easily sliding on the placement surface.

[0014] According to another embodiment of the utility model or any of the foregoing embodiments, the shielding coating of the light guide plate is a screen-printed layer or a heat transfer film.

[0015] Beneficial effects of the utility model:

[0016] 1. This utility model forms a multi-point force-bearing structure by using multiple evenly distributed support rods and longitudinal and transverse reinforcing ribs, which improves the load-bearing capacity of the panel and prevents significant deformation when heavy crystals are placed there for a long time.

[0017] 2. The structural design of this utility model, with the light guide plate embedded from the top and supported by the bottom support block, ensures that the force direction of the light guide plate is consistent with the embedding direction, preventing it from being pushed out due to heavy pressure or vibration, thus making the structure more reliable. A coating of the same color as the panel is printed or transferred at the contact area between the light guide plate and the support block, effectively hiding transparent adhesive residue and resulting in a smooth and consistent overall appearance, significantly improving the product's aesthetics.

At least four evenly arranged anti-slip pads 8 are installed on the bottom of the light body 3 to prevent the light body 3 from easily sliding on the placement surface.

[0028] like Figure 3 , 4 As shown in Figure 5, panel 1 is provided with a buckle for insertion into lamp body 3. A support block 6 is provided below the insertion opening of panel 1, and the support block 6 has the same shape as the edge of the insertion opening. The support block 6 includes a support part that supports the light guide plate 2 and a connecting part that connects to the bottom surface of panel 1. The lower surface of panel 1 is also provided with crisscrossing reinforcing ribs 7, at least some of which are connected to the support block 6. There are at least three support rods 5, and they are hollow structures. The width of the support block 6 is not less than 4mm, and the thickness is not less than 1.2mm. As a reinforcing structure, the parameters of the support block 6 suitable for the weight of the laser-engraved crystal were obtained through repeated experiments, resulting in the best support effect. The support block 6, reinforcing ribs 7, and panel 1 are integrally injection molded, and the support rods 5 and lamp body 3 are integrally injection molded.

[0029] like Figure 4 , 5 As shown in Figure 6, the light guide plate 2 is installed inside the recess of the panel 1, and its bottom is supported by the support block 6 of the panel 1 in contact with it. The part of the light guide plate 2 in contact with the support block 6 is coated with a coating of the same color as the panel 1. The shielding coating 9 of the light guide plate 2 is a screen-printed layer or a heat transfer film.

[0030] The working principle of this utility model:

[0031] The panel 1 of this utility model is the upper surface component of the display lamp, with an insertion opening in the middle. The light guide plate 2 is made of transparent acrylic or high-transmittance PC material, with its upper surface flush with the panel 1 and its lower surface tightly attached to the support block 6. After the light guide plate 2 is inserted into the insertion opening of the panel 1 from top to bottom, it is fixed by adhesive. The adhesive area is printed with a coating of the same color as the panel 1 to form a masking layer to prevent adhesive residue from being exposed. The light-emitting plate 4 is installed at the bottom of the lamp body 3 to support the LED light source.
