Abstract
Description
Technical Field
[0001] This utility model relates to the field of flexible LED device packaging technology, specifically a packaging structure for flexible LED devices. Background Technology
[0002] Flexible LED device packaging refers to the process of protecting and integrating LED chips through specific processes, making them independent devices that can be directly applied to circuits or lighting fixtures.
[0003] Traditional flexible LED device packaging structures typically involve fixing the flexible LED device to the top of a substrate and then using a protective soft shell to shield it. However, while protecting the flexible LED, traditional methods often compromise its cooling stability by reducing moisture and oxygen permeability, thus impacting its lifespan. Furthermore, traditional methods make it difficult to easily remove the protective shell for maintenance, hindering reliable upkeep. Utility Model Content
[0004] To address the shortcomings of existing technologies, this invention provides a packaging structure for flexible LED devices, thereby solving the problems mentioned in the background section.
[0005] This utility model provides the following technical solution: a packaging structure for flexible LED devices, including a substrate, a flexible LED device body disposed on the top of the substrate, a side frame fixedly mounted on the top of the substrate, a copper heat sink fixedly mounted on the inner wall of the side frame, a thermally conductive and insulating elastic rubber rod fixedly mounted on the inner wall of the copper heat sink, and the side of the thermally conductive and insulating elastic rubber rod being connected to the side of the flexible LED device body, an auxiliary block fixedly mounted on the top of the side frame, and a protective soft shell disposed on the top of the flexible LED device body.
[0006] As a preferred embodiment of this utility model, the top of the substrate is coated with a flexible LED strip adhesive layer, and the top of the flexible LED strip adhesive layer is fixedly assembled with the bottom of the flexible LED device body.
[0007] As a preferred embodiment of the present invention, the auxiliary block has a sliding groove on its side, a slider is slidably connected to the inner wall of the sliding groove, and a clamping frame is fixedly mounted on the side of the slider.
[0008] As a preferred technical solution of this utility model, the side of the clamping frame is provided with a slot, and the inner wall of the slot is engaged with a clamping rod, and the side of the clamping rod is fixedly assembled with the side of the protective soft shell.
[0009] As a preferred embodiment of this utility model, the number of auxiliary blocks is four, and each of the four auxiliary blocks has a sliding groove on both sides near the inner wall of the side frame, and a slider is slidably connected to the inner wall of each of the eight sliding grooves.
[0010] As a preferred embodiment of this utility model, the number of copper heat sinks is four, and the sides of the four copper heat sinks are respectively fixedly assembled with the inner walls of the side frame near the four sides. The number of thermally conductive and insulating elastic rubber rods is four, and the four thermally conductive and insulating elastic rubber rods are arranged in pairs facing each other on the top of the substrate.
[0011] Compared with the prior art, the present invention has the following beneficial effects:
[0012] 1. The encapsulation structure for flexible LED devices uses a copper heat sink and a thermally conductive and insulating elastic rubber rod in combination. When the protective soft shell and side frame encapsulate and protect the flexible LED device body, the thermally conductive and insulating elastic rubber rod assists the flexible LED device body in conducting heat and supplies the heat to the copper heat sink. The copper heat sink then assists in dissipating heat externally, thereby preventing the heat from being concentrated and stored during the operation of the flexible LED device, which would affect its service life.
[0013] 2. Furthermore, the packaging structure for flexible LED devices, through the cooperation of the clamping frame and the auxiliary block, allows the clamping frame to move on the side of the auxiliary block, thereby assisting the slider to slide in the inner wall of the groove, and thus assisting the inner wall of the clamping frame to move away from the side of the protective soft shell, thereby facilitating the movement of the protective soft shell away from the flexible LED device body, thereby facilitating the maintenance of the flexible LED device body, and thus improving the maintenance efficiency of the device.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] Please see Figures 1-6 A packaging structure for flexible LED devices includes a substrate 1, a flexible LED device body 2 disposed on the top of the substrate 1, a side frame 4 fixedly mounted on the top of the substrate 1, a copper heat sink 5 fixedly mounted on the inner wall of the side frame 4, a thermally conductive and insulating elastic rubber rod 6 fixedly mounted on the inner wall of the copper heat sink 5, and the side of the thermally conductive and insulating elastic rubber rod 6 connected to the side of the flexible LED device body 2, an auxiliary block 8 fixedly mounted on the top of the side frame 4, and a protective soft shell 12 disposed on the top of the flexible LED device body 2. Through the cooperation of the side frame 4 and the copper heat sink 5, the side frame 4 assists in the stable mounting of the copper heat sink 5, thereby facilitating the external heat conduction of the copper heat sink 5 in conjunction with the thermally conductive and insulating elastic rubber rod 6, thus assisting the flexible LED device body 2 in stable use.
[0023] like Figure 2 As shown, in a preferred embodiment, the top of the substrate 1 is coated with a flexible LED strip epoxy layer 3, and the top of the flexible LED strip epoxy layer 3 is fixedly assembled with the bottom of the flexible LED device body 2. The addition of the flexible LED strip epoxy layer 3 helps to stably mount the flexible LED device body 2 and the substrate 1.
[0024] like Figure 5 and Figure 6 As shown, in a preferred embodiment, the auxiliary block 8 has a groove 9 on its side, and a slider 10 is slidably connected to the inner wall of the groove 9. A clamping frame 7 is fixedly mounted on the side of the slider 10. By using the groove 9 and the slider 10 together, the side of the slider 10 slides on the inner wall of the groove 9, thereby using the slider 10 to drive the clamping frame 7 for convenient position adjustment.
[0025] In a preferred embodiment, the clamping frame 7 has a slot 11 on its side, and a clamping rod 13 is engaged with the inner wall of the slot 11. The side of the clamping rod 13 is fixedly assembled with the side of the protective soft shell 12. Through the cooperation of the clamping rod 13 and the slot 11, the side of the clamping rod 13 is engaged with the inner wall of the slot 11, thereby assisting the clamping rod 13 in driving the protective soft shell 12 to be stably erected.
[0026] In a preferred embodiment, there are four auxiliary blocks 8, and each of the four auxiliary blocks 8 has a sliding groove 9 on both sides near the inner wall of the side frame 4. Each of the eight sliding grooves 9 has a slider 10 slidably connected to its inner wall. By adding the four auxiliary blocks 8, the four clamping frames 7 can be conveniently adjusted in position.
[0027] In a preferred embodiment, there are four copper heat sinks 5, and the sides of the four copper heat sinks 5 are fixedly assembled to the inner walls of the side frame 4 near the four sides. There are also four thermally conductive and insulating elastic rubber rods 6, which are arranged in pairs facing each other on the top of the substrate 1. By adding the four copper heat sinks 5, the internal heat conduction of the encapsulated device can be stably conducted to the outside. By adding the four thermally conductive and insulating elastic rubber rods 6, the flexible LED device body 2 can be assisted in heat conduction while being limited, thereby further improving the stable use of the device.
[0028] Working principle: When the device is in use, when the protective soft shell 12 and the side frame 4 encapsulate and protect the flexible LED device body 2, the thermally conductive and insulating elastic rubber rod 6 assists the flexible LED device body 2 in conducting heat and supplying the heat to the copper heat sink 5. The copper heat sink 5 then assists in dissipating heat externally, thus preventing the flexible LED device from accumulating heat during operation and affecting its lifespan. The clamping frame 7 moves to the side of the auxiliary block 8, thereby assisting the slider 10 in sliding within the inner wall of the groove 9. This helps the inner wall of the clamping frame 7 move away from the side of the protective soft shell 12, facilitating the movement of the protective soft shell 12 away from the flexible LED device body 2. This makes it easier to maintain the flexible LED device body 2 and improves the maintenance efficiency of the device.
