Abstract
Description
Technical Field
[0001] This utility model relates to the field of LED manufacturing technology, and in particular to a partitioned LED bracket. Background Technology
[0002] LEDs have many advantages such as high luminous efficacy, long lifespan, energy saving, and environmental friendliness, and are increasingly widely used in many fields, such as indoor lighting, outdoor lighting, and backlighting.
[0003] In the existing technology, LEDs need to be encapsulated on an LED bracket. The conventional LED bracket is cup-shaped, with an insulating plastic material flush with the bottom of the cup to distinguish the positive and negative terminals of the LED. However, because the insulating plastic material is flush with the bottom of the cup, this structure can only perform one dispensing operation during encapsulation, and cannot distinguish the dispensing operation, resulting in many process limitations, which in turn affects the performance of the encapsulated LED. Utility Model Content
[0004] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a partitioned LED bracket. This aims to solve the problem that in existing technologies, the LED bracket is bowl-shaped with an insulating plastic material flush with the bottom of the bowl to distinguish the positive and negative terminals of the LED. However, because the insulating plastic material is flush with the bottom of the bowl, this structure can only perform one dispensing operation during encapsulation, making it impossible to distinguish between different dispensing operations. This results in many limitations in the process and affects the performance of the encapsulated LED.
[0005] To achieve the above objectives, this utility model is implemented through the following technical solution:
[0006] A partitioned LED bracket has a bowl bottom and bowl walls. The bowl walls are stepped from the inside out to form a set of steps. The set of steps includes multiple steps, and a stepped platform is formed between adjacent steps. The bowl bottom has one or more spacers. The spacers are used to form multiple independent partitions in the bowl bottom. The stepped platforms and the spacers are used to isolate the adhesive layer. Each independent partition is used to accommodate an LED chip and the adhesive layer.
[0007] According to one aspect of the above technical solution, the stage group includes a first stage and a second stage from bottom to top, and both the first stage and the second stage are inclined from the inside to the outside.
[0008] According to one aspect of the above technical solution, there is one partition, and a first independent partition and a second independent partition are formed between the partition and the bowl wall.
[0009] According to one aspect of the above technical solution, the top surface height of the spacer is consistent with the top surface height of the stepped platform formed between the first stage and the second stage.
[0010] According to one aspect of the above technical solution, the height of the spacer is 200μm-350μm.
[0011] According to one aspect of the above technical solution, the first independent partition is provided with a positive electrode pad, and the second independent partition is provided with a negative electrode pad.
[0012] According to one aspect of the above technical solution, the partitioned LED bracket also includes a bowl-shaped surface, the surface of which is recessed to form a foolproof notch, which is used to distinguish the positive and negative electrodes of the independent partitions.
[0013] According to one aspect of the above technical solution, the spacer is made of insulating plastic material.
[0014] According to one aspect of the above technical solution, there are two partitions, which are perpendicular to each other, and the two partitions form four independent zones with the bowl wall.
[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0016] By arranging the bowl wall in a stepped manner from the inside out, a stepped platform can be formed between adjacent steps. At the same time, one or more spacers are provided in the bottom of the bowl to form multiple independent zones. When LED chips need to be installed in the bottom of the bowl, different LED chips can be installed independently according to the independent zones. Each independent zone has its own positive and negative pads. When dispensing and encapsulating LED chips, this application can perform the dispensing process separately in each independent zone through the isolation effect of the spacers, which facilitates the control of the amount of glue. Unlike the prior art, which can only perform dispensing in a single operation at the bottom of the bowl, if adjacent LED chips are covered with different fluorescent glues, a single dispensing operation will cause the adjacent fluorescent glues to interfere with each other, thereby affecting the quality of the finished LED.
[0017] Meanwhile, the spacer can also block the light emitted by adjacent LED chips, better control the light-emitting effect of the LEDs, and avoid the light from the LED chips affecting each other.
[0018] Finally, the combination of the stepped platform and the spacer can confine the adhesive in the fluorescent glue below the top surface of the stepped platform and the spacer. If the stepped platform is not set, the adhesive will climb up, making it easier for the adhesive layer to peel off from the LED bracket after the adhesive has cured, which will lead to the failure of the LED product.
[0019] The partitioned LED bracket in this invention features a simple structural design, focusing solely on the injection mold. Unlike conventional multi-unit structures that require separate positive and negative electrodes for each cup, which leads to excessively small solder pad areas, this design suffers from several drawbacks: ① inability to precisely process the metal structure, resulting in significant disadvantages in airtightness; ② small individual solder pad areas lead to poor heat dissipation, reducing overall reliability; and ③ complex structures and difficult manufacturing processes increase costs. Therefore, the simple structure of this invention improves airtightness, reliability, and cost, while also simplifying the packaging process. Attached Figure Description

[0026] The following detailed description, in conjunction with the accompanying drawings, will further illustrate this utility model. Detailed Implementation
[0027] To facilitate understanding of this utility model, a more complete description will be given below with reference to the accompanying drawings. Several embodiments of this utility model are shown in the drawings. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of this utility model will be more thorough and complete.
[0028] It should be noted that when a component is said to be "fixed to" another component, it can be directly on the other component or there may be an intervening component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.
[0029] 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 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.
[0030] Please see Figures 1 to 3 The image shows a partitioned LED bracket 100 according to the first embodiment of the present invention, which has a bowl bottom 10 and a bowl wall 30. The bowl wall 30 is stepped from the inside to the outside to form a set of steps. The set of steps includes multiple steps, and a stepped platform 33 is formed between adjacent steps. The bowl bottom 10 is provided with one or more spacers 20. The spacers 20 are used to form multiple independent partitions in the bowl bottom 10. The stepped platform 33 and the spacers 20 are used to isolate the adhesive layer. Each independent partition is used to accommodate an LED chip and the adhesive layer.
[0031] Understandably, this utility model, by setting the bowl wall 30 in a stepped manner from the inside out, can form a stepped platform 33 between adjacent steps. At the same time, one or more spacer platforms 20 are provided in the bowl bottom 10. The spacer platforms 20 are used to form multiple independent partitions in the bowl bottom 10. When it is necessary to install LED chips in the bowl bottom 10, different LED chips can be installed independently according to the independent partitions. Each independent partition has its own positive and negative electrode pads. When dispensing and encapsulating LED chips, this application can perform the dispensing process separately in each independent partition through the isolation effect of the spacer platforms 20, which facilitates the control of glue amount. Unlike the prior art, which can only perform dispensing in the bowl bottom 10 in a single operation, if adjacent LED chips are covered with different fluorescent glues, a single dispensing operation will cause the adjacent fluorescent glues to affect each other, thereby affecting the quality of the finished LED.
[0032] Meanwhile, the spacer 20 can also block the light emitted by adjacent LED chips, better control the light-emitting effect of the LED, and avoid mutual interference between the light of the LED chips;
[0033] Finally, the cooperation between the stepped platform 33 and the spacer 20 can confine the adhesive in the fluorescent adhesive to below the top surface of the stepped platform 33 and the spacer 20. If the stepped platform 33 is not set, the adhesive will climb up, making it easier for the adhesive layer to peel off from the LED bracket after the adhesive has cured, which will lead to the failure of the LED product.
[0034] The partitioned LED bracket 100 in this invention features a simple structural design, focusing solely on the injection mold. Unlike conventional multi-unit structures that require separate positive and negative electrodes for each cup, which leads to excessively small solder pad areas, this design suffers from several drawbacks: ① inability to precisely process the metal structure, resulting in significant disadvantages in airtightness; ② small individual solder pad areas lead to poor heat dissipation and reduced overall reliability; ③ complex structure and difficult manufacturing processes result in increased costs. Therefore, the simple structure of this invention improves airtightness, reliability, and cost, while also simplifying the packaging process.
[0035] Specifically, in this embodiment, the stage group includes a first stage 31 and a second stage 32 from bottom to top, and both the first stage 31 and the second stage 32 are inclined from the inside to the outside; there is one spacer 20, and a first independent partition 11 and a second independent partition 12 are formed between the spacer 20 and the bowl wall 30; the first independent partition 11 is provided with a positive electrode pad, and the second independent partition 12 is provided with a negative electrode pad.
[0036] Understandably, this embodiment uses two independent partitions as an example. Each independent partition has an LED chip. The first independent partition 11 has a positive pad, and the second independent partition 12 has a negative pad. Then the LED chip and the pad are wired together. The first stage 31 and the second stage 32 are both tilted from the inside to the outside so that the light emitted from the LED chip can be refracted back when it hits the bowl wall 30, which fully improves the light intensity inside the bowl bottom 10.
[0037] It should be noted that, as Figure 4 As shown, in other embodiments, two spacer platforms 20 may be provided, which are perpendicular to each other. The two spacer platforms 20 and the bowl wall 30 form four independent partitions 50, with positive and negative pads arranged sequentially.
[0038] Furthermore, the top surface height of the spacer 20 is consistent with the top surface height of the stepped platform 33 formed between the first stage 31 and the second stage 32.
[0039] Understandably, for example, if it is necessary to apply fluorescent adhesive doped with yellow phosphor to the LED chip in the first independent zone 11 and fluorescent adhesive doped with green phosphor to the LED chip in the second independent zone 12, then the top height of the spacer 20 can be designed to be consistent with the top height of the stepped platform 33 formed between the first stage 31 and the second stage 32. The fluorescent adhesive doped with yellow phosphor and the fluorescent adhesive doped with green phosphor can be at the same height as the spacer 20 or lower than the height of the spacer 20, which can effectively reduce the light mixing / reabsorption phenomenon of the zones.
[0040] Preferably, the height of the spacer stage 20 is 200μm-350μm (which can be adjusted according to factors such as chip height, line arc height, and specific product type, and may exceed this range).
[0041] Understandably, by changing the injection mold structure, the spacer 20, which was originally flush with the pads, can be made to have a certain height. This height depends on different products, different chip heights, and the arc of the wire used. For example, in the commonly used 2835 bracket, the height of the spacer 20 is recommended to be set between 200μm and 350μm.
[0042] Furthermore, the partitioned LED bracket 100 also includes a bowl 40, the surface of which is recessed to form a foolproof notch 41, which is used to distinguish the positive and negative poles of the independent partitions.
[0043] It is understandable that, for example, if the industry convention is to place the foolproof opening 41 at the negative terminal, then in this embodiment, the foolproof opening 41 is provided on the bowl surface 40 at the second independent partition 12.
[0044] Preferably, the spacer 20 is made of insulating plastic material.
[0045] In addition, the shape of the LED partition bracket includes, but is not limited to, square cups, such as round cups, medium cups, oval cups, etc. The above design for independent partitions takes 55 points as an example, including but not limited to the size ratio of 55 points of solder pads. The size of each independent partition can be adjusted according to the specific scheme. When there are more than two independent partitions: ① it can be designed as a double solder pad structure (i.e., only distinguishing between positive and negative poles); ② it can be designed as a single bowl cup with a single solder pad (only one positive pole and one negative pole are designed); ③ it can be designed as a single bowl cup with a single solder pad (multiple positive poles and multiple negative poles are designed).
[0046] In summary, the partitioned LED bracket in the above embodiments of this utility model has a simple structural design, which divides the bottom of the bowl into multiple independent partitions, thereby improving the dispensing quality.
