Description

Technical Field

[0001] This invention relates to the field of LED lighting technology, specifically to a lighting fixture with a glue-coated lens and its manufacturing process. Background Technology

[0002] LEDs are commonly used light-emitting devices that release light through the recombination of electrons and holes, and are widely used in the lighting field. LEDs can efficiently convert electrical energy into light energy and have a wide range of applications in modern society, such as lighting, flat panel displays, and medical devices.

[0003] In the LED packaging process, a lens plate is usually designed on the LED light board to adjust the light field distribution or improve luminous efficiency. The lens plate has lens structures that correspond one-to-one with the LED chips; however, there will be gaps between the lens structures and the LED chips. The air in the gaps will cause interface loss, resulting in a decrease in the light emission efficiency of the LED chips; on the other hand, it will cause the LED chip pins to lack protection. Once moisture enters, the LED chip pins will be prone to sulfidation.

[0004] Therefore, during the LED lighting encapsulation process, protective adhesive needs to be injected into the lens structure to expel air from the lens, thereby protecting the LED chip and improving luminous efficiency. Currently, the conventional method for injecting protective adhesive into the lens structure involves creating injection holes and venting holes on both sides of each lens structure, and then connecting the dispensing machine to the injection holes of each lens structure sequentially to inject the protective adhesive. However, this injection method is very cumbersome, thus prolonging the LED encapsulation process time; more importantly, this method is prone to situations where the protective adhesive fails to completely fill the lens structure. Summary of the Invention

[0005] The purpose of this invention is to improve and innovate upon the shortcomings and problems existing in the prior art, and to provide a lamp with a glue-filled lens and its manufacturing process.

[0006] According to a first aspect of the present invention, a lamp fixture with a glue-filled lens is provided, comprising a lamp housing, a lamp plate mounted on the lamp housing, a lens plate mounted on the lamp plate, a plurality of lens structures disposed on the lens plate, lamp beads corresponding one-to-one with the lens structures disposed on the lamp plate, a sealing strip disposed between the edges of the lamp plate and the lens plate, the lamp plate being fixedly connected to the lens plate by screws, a recess being formed on the side of the lens structure opposite to the lamp plate, the recess being filled with a first protective adhesive, a glue-filling hole and a vent hole being provided on the lens plate, a second protective adhesive being filled in the gap between the lamp plate and the lens plate, the second protective adhesive being injected into the gap between the lamp plate and the lens plate through the glue-filling hole, and the vent hole being used to expel air from the gap between the lamp plate and the lens plate.

[0007] A further embodiment is that the LED bead is a multi-color LED bead, which includes light-emitting chips of four colors: red, yellow, blue, and green. The first protective adhesive and the second protective adhesive have different refractive indices. The first protective adhesive is prepared by mixing the A and B components of LED encapsulation adhesive in a 1:1 weight ratio. The second protective adhesive is prepared by first mixing the A and B components of LED encapsulation adhesive in a 1:1 weight ratio, and then adding LED diffusion powder to the mixed LED encapsulation adhesive. The added LED diffusion powder accounts for 0.5%-10% of the total mass.

[0008] A further embodiment is that an annular groove is provided between the lamp housing and the lamp plate, and an annular protrusion is provided on the edge of the lens plate to match the annular groove. A sealing groove for accommodating a sealing strip is opened on the annular protrusion, and the screw passes through the annular protrusion on the lens plate and is screwed into the threaded hole on the bottom wall of the annular groove.

[0009] A further embodiment is that the lamp plate has several grooves in the middle, and the lens plate has a sealing ring corresponding to the groove on the side opposite to the lamp plate. The screw passes through the sealing ring and is screwed into the threaded hole on the bottom wall of the groove.

[0010] A further option is to have the top of the first protective adhesive at the same level as or above the surface of the lens plate.

[0011] According to a second aspect of the present invention, a manufacturing process for a luminaire with a glue-coated lens is provided, specifically including the following steps: Prepare a first protective adhesive and fill the recess formed on the side of the lens structure opposite to the lamp board with the first protective adhesive; wherein, the lens structure is evenly distributed on the lens board, and the lens structure corresponds one-to-one with the lamp beads on the lamp board. After the first protective adhesive has solidified, install the lens plate onto the lamp plate; Prepare a second protective adhesive and inject it into the gap between the lens plate and the lamp plate through the injection hole on the lens plate until the second protective adhesive fills the gap between the lens plate and the lamp plate; during the filling process of the second protective adhesive, air is discharged from the vent hole. After the second protective adhesive has solidified, seal the injection hole and the vent hole.

[0012] A further solution is that filling the recess formed on the side of the lens structure opposite to the lamp panel with the first protective adhesive specifically includes: Prepare a grid plate that matches the lens structure. The mesh on the grid plate corresponds one-to-one with the lens structure. Fill the corresponding recesses of the lens structure with the first protective adhesive through the mesh on the grid plate. After the first protective adhesive has solidified, remove the mesh panel.

[0013] A further option is that the lamp bead is a multi-color LED lamp bead, which includes light-emitting chips of four colors: red, yellow, blue and green, and the first protective adhesive and the second protective adhesive have different refractive indices for light; Specifically, the preparation of the first protective adhesive includes: Mix the A and B components of the LED encapsulating adhesive in a 1:1 weight ratio. Thoroughly stir the mixed LED encapsulating adhesive A and B components until they are evenly mixed, and then place them in a vacuum machine for vacuum degassing. The preparation of the second protective adhesive specifically includes: Mix LED encapsulation adhesive A and B in a 1:1 weight ratio; Add LED diffusion powder to the prepared LED encapsulating adhesive, with the added LED diffusion powder accounting for 0.5%-10% by mass; The LED encapsulating adhesive and LED diffusion powder are thoroughly mixed, and then placed in a vacuum machine for vacuum degassing.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: The present invention discloses a lamp with a glue-filled lens and its manufacturing process. Before the lens plate is installed on the lamp plate, a first protective adhesive is pre-filled into the recess formed on the side of the lens structure opposite to the lamp plate. After the first protective adhesive solidifies, the lens plate is then installed on the lamp plate. Next, a second protective adhesive is injected into the gap between the lens plate and the lamp plate through the glue-filling hole on the lens plate until the second protective adhesive completely fills the gap. Thus, because the first protective adhesive is pre-filled into the recess corresponding to the lens structure, the second protective adhesive injected into the glue-filling hole can completely fill the gap between the lens plate and the lamp plate, preventing any gaps from being filled by the second protective adhesive. Furthermore, compared to the prior art where each lens structure is individually opened using a glue-filling machine, this method achieves a more efficient and comprehensive manufacturing process. This invention significantly improves glue injection efficiency compared to the cumbersome glue injection method using traditional injection holes. Furthermore, it eliminates the need for precise control of the glue volume, enhancing the flexibility and adaptability of the injection process and making the overall process more efficient and easier to implement. In addition, the first and second protective adhesives have different refractive indices. When the light emitted by the multi-color LED chip passes through the first and second protective adhesives sequentially, it is refracted at different angles. This facilitates the full mixing of red, yellow, blue, and green light emitted by the four-color LED chips, avoiding color separation. Moreover, with the addition of LED diffuser powder, the light emitted by the LED chip is scattered when it passes through the first protective adhesive, resulting in a more uniform light distribution and achieving uniform light mixing.

[0018] To make the objectives, features, and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0019] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0020] Example 1 Please see Figure 1-3This invention provides a lamp with a glue-filled lens. In this embodiment, the lamp can be a street lamp or an indoor lamp, depending on the specific circumstances. The lamp includes a lamp housing 1, on which a lamp plate 2 is mounted, and a lens plate 4 is disposed. The lamp plate 2 has evenly distributed LED beads 3. In this embodiment, the LED beads 3 are multi-color LED beads, each containing red, yellow, blue, and green light-emitting chips. The red, yellow, blue, and green light emitted by these chips are mixed to synthesize white light. The lens plate 4 has lens structures 41 corresponding to each LED bead 3. These lens structures 41 can adjust the light field distribution of the light source and improve luminous efficiency.

[0021] It should be noted that the side of the lens structure 41 facing away from the lamp panel 2 is convex outwards, while the side opposite to the lamp panel 2 is concave.

[0022] To allow the lens plate 4 to be mounted on the lamp plate 2 while preventing rainwater from entering the lamp plate 2, an annular groove 21 is provided between the lamp plate 2 and the lamp housing 1. An annular protrusion 42 is provided on the side of the lens plate 4 opposite to the lamp plate 2, and an annular sealing groove 43 is formed on the annular protrusion 42. The sealing groove 43 is used to accommodate a sealing strip (not shown in the figure). After the lens plate 4 and the lamp plate 2 are precisely aligned, screws are passed through the annular protrusion 42 to fix the lens plate 4 and the lamp plate 2 together. At this time, the sealing strip fits tightly against the edges of the lens plate 4 and the lamp plate 2, preventing rainwater from seeping in. To securely fix the lens plate 4 to the lamp plate 2, several grooves 22 are formed in the middle of the lamp plate 2. A sealing ring 5 is provided in the middle of the side of the lens plate 4 opposite to the lamp plate 2. Screws are then passed through the sealing ring 5 to fix the lens plate 4 and the lamp plate 2 together. At this time, the sealing ring 5 fits tightly against the middle of the lens plate 4 and the lamp plate 2, preventing rainwater from seeping in through the screw holes.

[0023] To prevent interference between the lens plate 4 and the LED beads 3 on the lamp plate 2, a receiving groove 44 is provided on the side of the lens plate 4 opposite to the lamp plate 2. After the lens plate 4 is installed on the lamp plate 2, the LED beads 3 on the lamp plate 2 are located in the receiving groove 44. It should be noted that when there is no filler between the lens plate 4 and the lamp plate 2, moisture will enter and cause oxidation of the LED bead 3 leads, resulting in sulfidation of the LED bead 3 leads, which will affect the performance of the LED bead 3. In addition, the light emitted by the LED light-emitting chip will pass through the air medium during the propagation process, which will cause interface loss and reduce the light emission efficiency of the LED light-emitting chip. Therefore, in this application, the recess formed on the side of the lens structure 41 opposite to the lamp plate 2 is filled with a first protective adhesive in advance. That is, the top of the first protective adhesive is at the same level as the surface of the lens plate 4, or higher than the surface of the lens plate 4 but does not affect the installation of the lens plate 4 on the lamp plate 2. After the first protective adhesive solidifies, the lens plate 4 and the lamp plate 2 are then fixed together with screws. Furthermore, this application pre-fabricates the lens plate 4 with an injection hole 6 and an vent hole 7; preferably, the injection hole 6 and the vent hole 7 are located at both ends of one diagonal line of the lens plate 4. After the lens plate 4 is installed on the lamp plate 2, the injection hole 6 is connected to the injection machine, which injects the second protective adhesive into the receiving groove 44 through the injection hole 6. At the same time, the air in the receiving groove 44 is discharged from the vent hole 7 until adhesive overflows from the vent hole 7, at which point the second protective adhesive fills the receiving groove 44. Since the first protective adhesive is pre-filled in the recess corresponding to the lens structure 41, the second protective adhesive injected into the injection hole 6 can fill the gap between the lens plate 4 and the lamp plate 2. This avoids light propagation in the air, thereby improving the luminous efficacy of the LED light-emitting chip by more than 10%; on the other hand, it can prevent moisture from entering the lamp plate 2 and causing sulfidation of the LED bead 3.

[0024] It should be noted that, since the LED bead 3 in this application is a multi-color LED bead, which includes light-emitting chips of four colors: red, yellow, blue, and green, and since it is white light synthesized by mixing the red, yellow, blue, and green light emitted by the four light-emitting chips, if the light emitted by the entire LED bead 3 is not uniformly mixed, obvious color separation will occur. Therefore, in this invention, the first protective adhesive is LED encapsulating adhesive, which is used to fill the pits corresponding to the lens structure 41. The A and B components of the LED encapsulating adhesive are mixed in a 1:1 weight ratio, and then the A and B components are thoroughly stirred. After being stirred evenly, the mixture is placed in a vacuum machine for vacuum degassing to obtain the first protective adhesive. The second protective adhesive of this invention is an adhesive obtained by uniformly mixing LED encapsulating adhesive and LED diffusion powder. To prepare the second protective adhesive, the A and B components of the LED encapsulating adhesive are first mixed in a 1:1 weight ratio. Then, LED diffusing powder is added to the LED encapsulating adhesive at a mass ratio of 0.5%-10%. The LED encapsulating adhesive and LED diffusing powder are then thoroughly stirred. After uniform mixing, the mixture is placed in a vacuum chamber for degassing, thus obtaining the second protective adhesive. This process results in two advantages: firstly, the first and second protective adhesives have different refractive indices. When light emitted from the multi-color LED chip passes through the first and second protective adhesives sequentially, it is refracted at different angles, which helps to achieve uniform mixing of the multi-color light and avoids color separation. Secondly, the addition of LED diffusing powder causes scattering of light emitted from the LED chip when it passes through the first protective adhesive, resulting in a more uniform light distribution and achieving uniform light mixing.

[0025] Example 2 Please see Figure 4 The present invention also provides a manufacturing process for a lamp with a glue-filled lens, specifically including the following steps: Step S1: Prepare the first protective adhesive and fill the pit formed on the side of the lens structure 41 opposite to the lamp plate 2 with the first protective adhesive; wherein, the lens structure 41 is evenly distributed on the lens plate 4, and the lens structure 41 corresponds one-to-one with the lamp beads 3 on the lamp plate 2. Specifically, the first protective adhesive of the present invention is LED encapsulating adhesive, which is used as the adhesive to fill the pits corresponding to the lens structure 41. The A and B components of the LED encapsulating adhesive are mixed in a 1:1 weight ratio. First, the A and B components of the LED encapsulating adhesive are thoroughly stirred. After being stirred evenly, they are placed in a vacuum machine for vacuum degassing to obtain the first protective adhesive.

[0026] It should be noted that the side of the lens structure 41 facing away from the lamp panel 2 is convex outwards, while the side opposite to the lamp panel 2 is concave.

[0027] After the first protective adhesive is prepared, prepare a grid plate that matches the lens structure 41. The mesh on the grid plate corresponds one-to-one with the lens structure 41. Fill the pit with the first protective adhesive through the mesh on the grid plate. After the first protective adhesive has solidified, remove the grid plate.

[0028] Step S2: After the first protective adhesive has solidified, install the lens plate 4 onto the lamp plate 2; It should be noted that the lamp board 2 is pre-installed on the lamp housing 1 before the lens plate 4 is installed on the lamp board 2. Lamp beads 3 are evenly distributed on the lamp board 2; in this embodiment, the lamp beads 3 are multi-color LED beads, which include light-emitting chips of four colors: red, yellow, blue, and green. The red, yellow, blue, and green light emitted by the four-color light-emitting chips mix to synthesize white light.

[0029] In this embodiment, the lens plate 4 is fixed to the lamp plate 2 by screws. After the screws pass through the edge of the lens plate 4, they are threaded into the threaded holes on the lamp plate 2. A sealing strip is provided between the edges of the lens plate 4 and the lamp plate 2. When the screws fix the lens plate 4 and the lamp plate 2 together, the sealing strip is tightly fitted to the edges of the lens plate 4 and the lamp plate 2, which can prevent rainwater from seeping in.

[0030] In some preferred embodiments, in order to securely fix the lens plate 4 to the lamp plate 2, a plurality of grooves 22 are provided in the middle of the lamp plate 2. The bottom wall of the grooves 22 is provided with threaded holes. On the side of the lens plate 4 opposite to the lamp plate 2, a sealing ring 5 is provided that corresponds to the groove 22. The screw passes through the sealing ring 5 and is threadedly connected to the threaded hole in the bottom wall of the groove 22, thereby fixing the lens plate 4 and the middle of the lamp plate 2 together. At this time, the sealing ring 5 fits tightly with the middle of the lens plate 4 and the lamp plate 2, which can prevent rainwater from seeping in through the screw hole.

[0031] Step S3: Prepare the second protective adhesive. Inject the second protective adhesive into the gap between the lens plate 4 and the lamp plate 2 through the injection hole 6 on the lens plate 4 until the second protective adhesive fills the gap between the lens plate 4 and the lamp plate 2. During the filling process of the second protective adhesive, air is discharged from the exhaust hole 7. Specifically, the second protective adhesive of the present invention is selected from LED encapsulating adhesive and LED diffusion powder, which are mixed evenly and used as adhesive to fill the gap between lens plate 4 and lamp plate 2. First, the A and B components of LED encapsulating adhesive are mixed in a 1:1 weight ratio. Then, LED diffusion powder is added to the LED encapsulating adhesive, and the added LED diffusion powder accounts for 0.5%-10% of the mass. Then, the LED encapsulating adhesive and LED diffusion powder are thoroughly stirred. After being stirred evenly, the mixture is placed in a vacuum machine for vacuum degassing to obtain the second protective adhesive.

[0032] During the filling of the second protective adhesive, the injection hole 6 is connected to the adhesive injection machine. The adhesive injection machine injects the second protective adhesive into the gap between the lens plate 4 and the lamp plate 2 through the injection hole 6. At the same time, the air in the gap between the lens plate 4 and the lamp plate 2 is discharged from the vent hole 7 until adhesive overflows from the vent hole 7. At this time, the second protective adhesive fills the gap between the lens plate 4 and the lamp plate 2. Since the first protective adhesive is filled in the corresponding recess of the lens structure 41 in advance, the second protective adhesive injected through the injection hole 6 can fill the gap between the lens plate 4 and the lamp plate 2, and there will be no gaps that the second protective adhesive cannot fill. In this way, the light emitted by the LED light-emitting chip does not pass through the air medium when it travels from the lamp plate 2 to the lens plate 4, which can improve the luminous efficacy of the LED light-emitting chip by more than 10%. At the same time, the second protective adhesive can prevent moisture from entering the lamp plate 2 and causing sulfidation of the LED bead 3.

[0033] It should be noted that during the second protective adhesive dispensing process, the dispensing process needs to be continuous, and the amount of adhesive stored in the dispensing cylinder of the dispensing machine should be greater than the amount of adhesive to be dispensed.

[0034] It should be further explained that, due to the different formulations of the first and second protective adhesives in this invention, the refractive indices of the first and second protective adhesives are different. When the light emitted by the multi-primary-color light-emitting chip passes through the first and second protective adhesives in sequence, it will be refracted at different angles, which is beneficial to achieve uniform mixing of multi-primary-color light and avoid color separation. On the other hand, after adding LED diffuser powder, when the light emitted by the light-emitting chip passes through the second protective adhesive, the light will be scattered, making the light distribution more uniform, thereby achieving the purpose of uniform light mixing.

[0035] Step S4: After the second protective adhesive has solidified, seal the injection hole 6 and the vent hole 7; Specifically, after the second protective adhesive has solidified, the injection hole 6 and the vent hole 7 are sealed with glue.

[0036] In summary, this invention discloses a manufacturing process for a lamp with a glue-filled lens. Before the lens plate 4 is installed on the lamp plate 2, a first protective adhesive is pre-filled into the recess formed on the side of the lens structure 41 opposite to the lamp plate 2. After the first protective adhesive solidifies, the lens plate 4 is then installed on the lamp plate 2. Next, a second protective adhesive is injected into the gap between the lens plate 4 and the lamp plate 2 through the glue-filling hole 6 on the lens plate 4 until the gap is completely filled. Thus, because the first protective adhesive is pre-filled into the recess corresponding to the lens structure 41, the second protective adhesive injected into the glue-filling hole 6 can completely fill the gap between the lens plate 4 and the lamp plate 2, preventing any gaps from being filled. Furthermore, compared to the cumbersome method of individually filling each glue-filling hole on each lens structure 41 using a glue-filling machine in the prior art, this invention significantly improves glue-filling efficiency. Moreover, this invention eliminates the need for precise control of the glue amount, thereby enhancing the flexibility and adaptability of the glue-filling process, making the overall process more efficient and easier to implement.

[0037] It should be understood that those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims. Parts not described in detail in this specification are prior art known to those skilled in the art.
